Regis Heat sink Technology Co., Ltd. is a professional manufacturer of heat dissipation processing. Regis's products and services include various heat sinks, structural parts, heat dissipation analysis and heat dissipation scheme design. Our products are widely used in telecommunications, aerospace, automotive, industrial control, power electronics, medical equipment, security electronics, LED lighting and multimedia/consumer fields.
In the power battery system, excess heat is generated by the battery operation, and the heat is transferred through the contact between the battery or the module and the surface of the plate-shaped aluminum device, and is finally taken away by the cooling liquid passing through the internal flow channel of the device. This plate-type aluminum device is a liquid-cooled plate.
The weight of the cold plate has strict requirements, which comes from the pursuit of energy density in the power battery system. The cooling system that seriously reduces the energy density of the system is completely unacceptable to both customers and designers.
High reliability, working in road vehicle environment, vibration, shock, high and low temperature alternating environment, are relatively harsh working conditions for most products, and the power battery voltage is often hundreds of volts, coolant leakage is a serious problem, even if you use Coolant with good insulation performance, but after encountering external impurities, the insulation performance will be reduced immediately, therefore, the reliability of cold plate sealing is very important;
The heat dissipation power is large, and the excess heat generated during the working process of the power battery can be exported in time to avoid the occurrence of excessive temperature rise;
Liquid cold plates are responsible for transferring heat from surfaces with high thermal loads to the fluids used in liquid cooling systems. The performance of these components is critical to the overall effectiveness of the liquid system.
Cold plates are usually made of metal with flow paths machined in them for the heat transfer fluid to flow through. As the plates absorb electrical waste heat, they use liquid cooling to dissipate it through the flow path.
Cold plates provide local cooling by transferring heat from the equipment to a liquid that flows to a remote heat exchanger and dissipates into the environment or another liquid in a secondary cooling system.
