The working principle of cold plate liquid cooling server is to indirectly transfer the heat of heat-generating components to the cooling liquid enclosed in the circulation pipeline through a cold plate (usually a closed cavity made of high thermal conductivity metals such as copper and aluminum), and take away the heat through the cooling liquid.

Specifically, cold plate liquid cooling technology uses working fluid as the medium for intermediate heat transfer, transferring heat from the hot zone to the far end before cooling.

In this process, the working fluid is separated from the cooled object and does not come into direct contact with the electronic device. Instead, the heat of the cooled object is transferred to the coolant through efficient heat conduction components such as liquid cold plates.

Therefore, cold plate liquid cooling technology is also called indirect liquid cooling technology.

Water Block is abbreviated as cold plate, also known as heat absorbing head or heat absorbing box. Its function is to transfer the heat of the heat-generating components to the water-cooling liquid.

The water-cooling head is an important part of the CPU water-cooling radiator and is used to dissipate the heat of the CPU. The performance impact on the entire water cooling system is second only to the radiator. The bottom surface of the cold head is made of metals such as copper, aluminum, and silver with good heat absorption and thermal conductivity, so that the bottom surface directly contacts the heat-generating components to absorb heat, and then transfers the heat to the water-cooling liquid. According to the design characteristics of the internal water channel, we can roughly divide the cold head into four categories: flat plate type, conventional water channel type, micro-channel type, and jet type.

A complete PC water cooling system mainly includes:

water cooling plate, water pump, water tank, radiator, water pipe, and joints. From today on, we will mainly introduce water cooling plates. In fact, the principle of water cooling is basically the same as that of heat pipes. The function of the water cooling plate is to absorb heat and transfer it to the radiator for heat dissipation through the flow of water.

Due to the rapid development of computer hardware, the heat generated by various devices is getting bigger and bigger. Water cooling plates are no longer only used for CPUs.

Nowadays, there are corresponding water cooling blocks for GPU, north bridges, south bridges, and even hard disks and memory.
