In today’s world of electric vehicles, renewable energy and portable electronic devices, battery technology is developing at a rapid pace. However, as battery performance improves, temperature management has become a challenge that cannot be ignored. Batteries are susceptible to damage in high-temperature environments, while their performance may be affected at low temperatures. Therefore, battery cooling methods have become one of the key areas of research and development.
Passive Cooling
Passive cooling is the simplest way to conduct and dissipate heat by designing heat sinks, thermally conductive materials and structures. This method requires no external energy source, instead relying on natural heat conduction and convection to cool the battery. Although passive cooling is simple and easy to implement, it has limited effectiveness in high-temperature or high-power applications. In Trumonytechs, we can provide thermal conductive pad, gel, potting glue as passive cooling
Active Air Cooling
Active air cooling uses fans or airflow systems to draw ambient air into the battery pack to lower temperatures. This method is relatively low cost and suitable for most light-duty applications. However, in extreme environments, such as high temperatures or high humidity, air cooling may not provide sufficient heat dissipation.
Liquid Cooling
Liquid cooling technology is one of the methods currently widely used in electric vehicles and large-scale energy storage systems. Heat is absorbed and conducted by circulating a coolant, such as water or ethylene glycol, around the battery module. The liquid cooling system provides stable cooling over a wide temperature range and can adjust the temperature as needed. In Trumony, we can provide various liquid cooling solutions and components from design to manufacturing for you.
Phase Change Material Cooling
Phase change material cooling takes advantage of the material’s ability to absorb or release heat through phase changes when the temperature changes. This method is commonly used in smaller-scale electronic devices such as smartphones and tablets. Phase change material cooling systems can provide higher heat dissipation efficiency than traditional air cooling, but are typically more costly and require higher material selection and design requirements.
