Cooling Plate Guide: Basics for EV and BESS Buyers
Cooling Plate Guide: Basics for EV and BESS Buyers
A cooling plate is a thermal management component that removes heat from battery cells in electric vehicles (EVs) and battery energy storage systems (BESS). For procurement professionals entering the EV and energy storage supply chain, understanding the fundamentals of cooling plates—materials, designs, and manufacturing approaches—is essential for making informed sourcing decisions. This guide provides a fact-based introduction to cooling plates, focused on the product range and capabilities of Trumony Aluminum Limited, a manufacturer with relevant experience and certifications.
What Is a Cooling Plate?
A cooling plate, also called a cold plate or liquid cooling plate, is a heat exchanger that transfers thermal energy from battery cells to a circulating coolant. Trumony Aluminum Limited produces a range of cooling plates and cooling tubes designed for battery thermal management in electric vehicle, energy storage system, and powertrain industries. The company's cooling plates are made of Aluminum 3003, a widely used aluminum alloy for heat exchange applications. Typical models include the stamped cooling plate (TR-20260227), the brazing cooling plate (TR-20260220), and the liquid cooling plate for EV (TR-20260225). All share a common feature: customizable thickness and cooling efficiency to match specific project requirements.
Why Cooling Plates Matter for EV and BESS
Battery packs in EVs and BESS generate significant heat during operation, especially under high-temperature conditions or fast charging. Without effective cooling, cell temperatures rise, reducing performance and accelerating degradation. Liquid cooling plates provide a reliable method to maintain temperature uniformity across modules. According to Trumony's application data, cooling plates are used in 24/7 battery pack thermal management projects for both electric vehicles and energy storage systems. For example, an EV cooling plate (model TR-20260225) is commonly applied in France under high-temperature conditions, while an energy storage system cooling plate (model TR-20260226) serves similar scenarios in Andorra.
Key Product Types and Manufacturing Approaches
Trumony's cooling plate portfolio includes several structural configurations, each suited to different battery layouts and cooling requirements. Below is a summary based on verified product data:
Stamped Cooling Plate (TR-20260227)
A stamped cooling plate is formed by stamping aluminum sheets to create channels for coolant flow. It is lightweight and suitable for high-volume production. Trumony's stamped cooling plate is made of Aluminum 3003 with customized thickness and cooling efficiency.
Brazing Cooling Plate (TR-20260220)
Brazing cooling plates are fabricated by joining multiple aluminum layers under high temperature to form internal flow paths. This method enables complex channel designs and high structural integrity. Trumony's brazing cooling plate also uses Aluminum 3003 and supports custom dimensions.
Serpentine Cooling Tube (TR-20260230) and Snake Cooling Tube (TR-20260232)
These products are tubular cooling components—often called cooling tubes—designed for insertion between battery cells or modules. They offer a compact form factor and flexible layout. Both are made of Aluminum 3003 with customizable thickness and cooling efficiency.
Liquid Cooling Plate for Energy Storage (TR-20260228)
Specifically designed for stationary energy storage systems, this plate handles the thermal demands of large-format battery racks. It shares the same material (Aluminum 3003) and customization options as the EV variants.
Step-by-Step Selection Process
- Define thermal requirements: Determine the heat load, target temperature difference, and coolant flow rate for your battery pack.
- Choose a structural type: Select between stamped, brazed, or tube-based cooling plates based on your module geometry and production volume.
- Specify dimensions: Work with the supplier to define plate thickness, flow channel pattern, and inlet/outlet positions. Trumony offers customized thickness and cooling efficiency.
- Confirm material compatibility: Trumony uses Aluminum 3003, which is compatible with water-glycol coolants and provides good corrosion resistance.
- Verify manufacturing capabilities: Check that the supplier can meet your production schedule and quality standards. Trumony operates a 100,000 m² facility with an annual output of 600,000 units.
Use Cases in EV and BESS
Trumony cooling plates have been deployed in real-world projects. In the electric vehicle sector, a liquid cooling plate for EV (model TR-20260225) is used for battery pack heat dissipation in France under high-temperature conditions, operating continuously. In the energy storage sector, an energy storage system cooling plate (model TR-20260226) serves similar 24/7 applications in Andorra. These case studies illustrate the product's suitability for demanding thermal environments.
