Important applications of Liquid Cold plate in power batteries

With the rapid development of the electric vehicle market, the performance and safety of power batteries have attracted much attention. Liquid Cold plate plays a vital role in power batteries.

Liquid Cold plate can effectively manage the temperature of power batteries. During the operation of the vehicle, the battery will generate a lot of heat. If the heat is not dissipated in time, the excessive temperature will affect the performance and life of the battery and even cause safety problems. Liquid Cold plate is in close contact with the battery to quickly take away the heat and keep the battery in a suitable operating temperature range.

Liquid Cold plate

It has efficient heat dissipation performance. Liquid media can quickly absorb and transfer heat. Compared with air cooling and other methods, liquid cooling can more evenly reduce the battery temperature and reduce the temperature gradient, thereby improving the consistency of the overall battery performance.

In addition, Liquid Cold plate can also improve the reliability of the power battery system. A stable temperature environment helps to reduce battery aging and attenuation and extend the battery life. At the same time, under extreme working conditions, such as fast charging and driving in high temperature environments, Liquid Cold plate can ensure the safe operation of the battery and reduce the risk of thermal runaway.

When designing and applying Liquid Cold plate, many factors need to be considered. For example, the material selection of Liquid Cold Plate should take into account both thermal conductivity and corrosion resistance; the layout and pipeline design of the liquid cooling system should be reasonable to ensure the smooth flow and uniform distribution of the coolant.

Methods to deal with poor heat dissipation performance of Copper Heat Pipe Heat Sink

Aluminum vapor chamber

High-efficiency two-phase heat spreaders with lightweight aluminum construction. Designed for GPU, CPU, IGBT & power electronics and energy storage systems. Features: ultra-thin profile, high thermal conductivity, customizable size and shape.

Pulsating Heat Pipe (PHP)

Pulsating Heat Pipe (PHP, or Oscillating Heat Pipe) is advanced thermal management tech for high-power electronics, delivering high-efficiency, reliable heat sinks for aerospace, satellites, military equipment and VPX cooling chassis. Different from conventional heat pipes, PHP adopts a simple closed capillary loop charged with working fluid. Driven by fluid phase change, internal oscillation transfers heat rapidly with low flow resistance, requiring no pumps or moving components. Our optimized PHP heat sinks fit compact, mission-critical systems. Lightweight and miniaturized, they run stably and prolong device service life under extreme conditions such as microgravity and severe military environments. Core merits include outstanding heat conductivity, quick thermal response, robust environmental adaptability, low upkeep and broad operating temperature range.

Liquid Cooling Plate (LCP)

Liquid cold plates capture heat through the contact surface and remove heat via precision-engineered internal flow channels. Equipped with dedicated inlet and outlet ports, the liquid cold plate connects to external coolant pumps and cooling loop systems through tubing. The cooling liquid circulates continuously within the internal channel structure, rapidly and efficiently transferring heat away from heat sources.Our liquid cold plates are widely adopted for thermal management and heat dissipation in BESS energy storage systems, EV battery packs, high-power IGBT modules, industrial CPUs, GPUs and other high-power heat-generating equipment.

3DVC Cooler

The 3DVC cooler is developed based on conventional copper vapor chambers and copper heat pipes. It adopts an intercommunicated layout to form an integrated 3D vacuum cavity, with cooling fins welded between individual heat pipe units.
