Core requirements for liquid cooling plate technical quality

Liquid cooling plate is a form of indirect transfer of heat from the heating device to the cooling liquid enclosed in the circulation pipeline through a cold plate (usually a closed cavity made of thermally conductive metal such as copper and aluminum), and the heat is taken away through the cooling liquid .

liquid cooling plate

There are generally four core requirements for the technical quality of Liquid cooling plates: first, large heat dissipation power; second, high reliability to ensure the sealing of the cold plate; third, accurate heat dissipation design to avoid excessive temperature differences within the system; fourth, strict control of the weight of the cold plate , to avoid cooling systems that seriously reduce the energy density of the system.

The production process of tube Embedded liquid cooling plate is much more complicated than that of air-cooled radiator. The Liquid cooling plate process mainly includes raw material stamping - cleaning - fluxing - riveting - brazing - testing - sealing and other main processes. The general Liquid cooling plate production technology includes buried pipe process, profile + welding, machining + welding, Die casting + welding.

In addition, cold plate liquid cooling system equipment should undergo relevant tests and meet relevant national and industry standards and design requirements before leaving the factory, including testing and verification of appearance quality, performance, water quality performance, environmental adaptability, working methods, etc.

The development history of Thermosiphon

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.
