Why is a Thermal Mangement Plan for Enclosures Important?

Thermal Management Plan for Electrical Enclosures 

Manufacturing facilities have many electrical enclosures housing hundreds of thousands of dollars in high performance drives and electronics that are critical to production processes.  These critical electrical components generate a significant amount of heat and if not managed properly the high heat leads to premature aging and eventually failure, shutting down systems and resulting in downtime.  No manufacturing facility can afford downtime.

 

While having thermal management for your enclosures is important, having the correct cooling technology for your specific application that takes into account the cooling requirements and the ambient conditions is critical  The considerations to appropriate thermal management include heat load, ambient temperature range, the presence of particulates or debris, enclosure location and material among others.  Unfortunately, most manufacturing facilities lack a proper Thermal Management Plan to protect and extend the life of their equipment.  As a result, manufacturers suffer significant financial losses each year as a result of enclosures overheating. In many cases, this is preventable with a well-designed Thermal Management Plan.

Pfannenberg can Help Develop a Thermal Management Plan

Pfannenberg has over 65 years of experience keeping enclosures cool with our thermal management solutions and working with manufacturers to reduce costs and improve up time.  A good thermal management plan starts with a plant survey or thermal audit to evaluate the needs of the specific facility. Our Service and Support team offers a number of programs to gather the required information to determine if the correct cooling technology is in place and functioning properly to meet the needs of that particular facility.  A thermal management program from Pfannenberg can help:

Get Ready for Summer! 3 Steps to Prepare Your Enclosure Cooling Units for the Stress of the Summer Heat

Don’t Wait Until it’s Too Late!

With the summer heat just around the corner we want to help you prepare your electronics enclosure cooling units to stay up and running.

We put this Preventative Maintenance Video together to help you get ready.

Avoid critical component failures by following these 3 simple steps to ensure your enclosure cooling units stay up and runing all summer.

STEP 1: Make Sure Your Condenser Coils are Clean

The condenser coils are one of the most important components of your Cooling Unit, they ensure the reliable, cost efficient and long-term operation of your unit. When dirt, dust or debris builds up on your condenser coils, it can have a major negative effect on the performance of your cooling unit leading to increased run time and energy consumption.

STEP 2: Check Your Fan Motors and Inside/Outside Electrical Components

In order to prevent failure, the cooling unit’s fan motor and fan blades need to be inspected to determine wear and damage.  All the electrical components in the control box also need to be checked to make sure all connections aren’t damaged or loose.

STEP 3: Set Your Unit to the Recommended Proper Temperature

Pfannenberg sets the dip-switches on the control board to 95°F/35°C in the factory, and recommends that the dip switch settings are not altered.

Having the dip-switch temperature set to a lower point can cause damage not only to the cooling unit, but to the enclosure as well.  Changing the set point can cause the cooling unit to run excessively, possibly causing damage to the compressor and other components.  It can also cause the enclosure to produce condensate, possibly damaging electrical components inside the cabinet.

Thermal Management Protection Solutions For Battery Energy Storage Systems

By Adam Wells, Solutions Engineer, Pfannenberg USA

Cooling systems help achieve better battery performance, durability, and safety

Battery energy storage systems (BESS) are helping to transform how the world generates and consumes electricity as we transition from large-scale fossil fuel plants to renewable sources. The market for BESS is projected to grow at a compound annual growth rate (CAGR) of 30 percent from 2023-2033 according to IDTechEx. What’s more, the global cumulative stationary battery storage capacity is expected to reach 2 terawatt hours (TWh) within ten years.

What’s the catch? The market is challenged by the basic fact that electrochemical energy storage is notoriously vulnerable to overheating, risking sudden fire and explosion, in addition to causing degraded performance and shortened lifetime. Cooling systems are critically important for BESS, providing the thermal stability that is crucial for battery performance, durability, and safety. If applied correctly, the solutions will reduce battery degradation and damage, and minimize downtime.

Thermal Stability and Uniform Temperature 

In general, it is best to keep batteries at a moderate, consistent temperature to ensure their optimal performance and longevity. Exposure to extreme temperatures, either hot or cold, can damage batteries and cause hazardous events.

The specific temperature range that batteries require to operate safely varies depending on battery type and design. While new battery technologies are being developed every day, lithium-ion batteries continue to dominate energy storage systems due to falling battery costs and increased performance with less weight and space requirements giving better energy density compared to other battery types. It is likely that lithium-ion will continue to be the most common BESS technology for the foreseeable future.

According to the US National Renewable Energy Laboratory, the optimal temperature range for lithium-ion is between 15 °C and 35 °C. An ambient temperature of about 20°C or slightly below (“room temperature”) is ideal; if a battery operates at 30°C, its lifetime is reduced by 20 percent. At 40°C, the losses in lifetime approach 40 percent, and if batteries are charged and discharged at 45°C, the lifetime is only half of what can be expected at 20°C.

It is also equally important to maintain uniform temperature throughout the system. Avoiding hot spots is crucial to preventing damage and mitigating the risk of triggering a chain reaction that leads to catastrophic thermal runaway.

Causes of Battery Overheating

One key factor contributing to overheating is use in applications that require rapid charging/ discharging. These are referred to as having a high C-rate, defined as the charging or discharging current divided by the capacity (the amount of energy the battery can hold). Applications with a  high C-rate and frequent cycling generate more heat.

Another factor is high ambient temperature, which can damage batteries in several ways. Elevated temperatures lead to an increased rate of side reactions, causing attrition of active material and resulting in a build-up of resistance at the electrode surface. Operation of lithium-ion batteries at high temperatures will also accelerate the aging process and lead to performance degradation.

Paradoxically, low ambient temperatures can cause more problems with internal overheating than high ambient temperatures. Cold temperatures can result in viscosity changes in the electrolyte that lead to sluggish ion transport, resulting in higher resistance and heat generation.

Designing an Optimal Cooling Solution – Liquid or Air Cooling?

BESS thermal management solutions include liquid and air cooling; the optimal solution depends primarily on the application’s C-rate and environmental conditions. The most demanding thermal management applications, such as large-scale BESS installation and high C-rate applications, require active liquid cooling. Smaller installations with low C-rate applications can be safely and efficiently operated with air cooling.

Liquid cooling

Liquid cooling is extremely effective at dissipating large amounts of heat and maintaining uniform temperatures throughout the battery pack, thereby allowing BESS designs that achieve higher energy density and safely support  high C-rate applications.

Multiple versions of chillers are available to optimize the layout of the cooling system. For example, Pfannenberg offers two layout options: A stand-alone chiller can be placed inside the BESS. Each unit provides up to 12kW of cooling, and multiple units can be easily combined to support the highest cooling load requirements. Alternatively, a compact version is designed to be mounted outdoors on the cabinet door, for a small footprint that allows easy integration inside battery cabinets and enclosures. Both solutions safely operate between -25 and +50°C and offer up to 800 V DC power supply to directly connect with the battery system, all while not needing any power conversion.

Air cooling

Air cooling systems provide a cost-effective cooling solution for smaller stationary energy storage systems operating at a relatively low C-rate.

For example, Pfannenberg’s DTS Cooling Unit seals out the ambient air, and then cools and re-circulates clean, cool air through the enclosure. The closed loop design isolates the external ambient air from the internally conditioned air eliminating the risk of contaminants entering the cabinet. Thehermetically sealed compressor guarantees 100 percent cooling capacity efficiency.

For applications where the ambient air is always cooler than the temperature required inside the enclosure, filter fans, which use natural convection of the air to circulate air and dissipate heat, are extremely cost-effective.

Energy storage plays an important role in the transition towards a carbon-neutral society. BESS systems depend on cooling systems that provide the thermal stability that is crucial for battery performance, durability, and safety. and if applied correctly, will reduce battery degradation and damage, and minimize downtime.

Thermal Management Protection Solutions For Edge Computing Environments

By Jonathan LaPorta, Pfannenberg USA

Select the right option to ensure continuous operation of senstive electronics

Edge computing – placing application logic as close to the source of data as possible – reduces latency, optimizes bandwidth usage, and minimizes costs, all while increasing visibility and control, speeding up processing, and enhancing user experience. The challenge is that enclosures used to protect distributed computer equipment from the immediate environment oftentrap heat generated by the electronics. Read on to learn about thermal protection solutions that ensure continuous operation of sensitive electronics in edge computing environments.

Edge computing graphic

 

Benefits of Edge Computing Fuels Explosive Growth

The adoption of edge computing is accelerating for mission-critical computer components in factories, warehouses, retail stores, hospitals, and college campuses – and indeed in most other sectors. The explosive growth is fueled by megatrends like digitization, the internet of things (IoT), and automation.

Key examples include high-definition video cameras that generate masses of data; machine vision systems used in manufacturing to perform imaging-based automatic inspections; hospitals, which have to store and process medical sensor data and digital health records; and warehouses and retail stores running inventory and point-of-sale systems.

All that data needs to be processed somewhere, and it is usually much faster and more efficient to do it close to the edge where people and things produce and use that information. Keeping and processing data at the edge can also enhance reliability, security, and privacy by minimizing the transmission of sensitive information and exposure to network failures and malicious attacks.

 

Protecting Distributed Components is Critical

In edge computing environments, computing equipment is located outside of a climate-controlled data center. Servers and networking gear are often placed in crowded factory floor spaces, up in warehouse rafters, or in closets. They may be located in inhospitable environments, with high ambient temperatures, or dust- and oil-filled air. That is why distributed computer equipment is typically placed in enclosures for protection. Unfortunately, the enclosures themselves trap heat generated by the electronics, so they require protection from overheating.

 

Simple, Proven Cooling Solution 

A variety of cooling methods have proven effective for thermal management of electrical enclosures. Filter fans are an economical solution when the ambient temperature is always lower than the temperature required by the computer components inside. One example is Pfannenberg’s new Datawind Filterfan®, which has a temperature indicator and is mounted externally to the enclosure to enable full use of all racks within the bays.

 

More Challenging Cooling Applications 

Some applications require enclosures specially designed for challenging environments, from weather and impact-resistant outdoor enclosures to tightly sealed stainless steel enclosures for food production facilities that must withstand high pressure cleaning.

A closed loop cooling system is required when the interior air of the electrical enclosure must be protected from the exterior environment. Air to air technology is one of the more energy efficient technologies to use when there is a temperature difference between the internal target temperature and the surrounding temperature (∆T≥10°C). Pfannenberg’s Kinetic System™ (PKS) Series Air to Air Heat Exchangers remove heat from inside of the enclosure to the cooler environment using the least amount of energy while still providing a closed loop ingress protection.

If the electronics generate a high heat load and/or the ambient air is too warm to provide adequate cooling, an active cooling system such as the Pfannenberg DTS Series of side mounted cooling units may be required. These air conditioning systems utilize a compressor for cooling in a closed loop design that isolates the interior of the enclosure from the exterior environment.

Ideal for extremely demanding industrial and outdoor applications, Pfannenberg’s DTS units provide NEMA 4 level of protection from washdown conditions and caustic air and can operate in ambient temperatures up to 140° F (60° C).

By implementing the optimal cooling solution for distributed components operators can take advantage of edge computing’s many benefits while protecting mission critical IT infrastructure from overheating.
