Description
Technical Field
The invention relates to the field of server heat dissipation, in particular to a whole plate structure of a GPU cold plate radiator.
Background
Along with the increase of power consumption of various server products, the design of a radiator of a server is more and more complex, but aiming at the increase of high-power-consumption components such as product chips, the traditional air-cooling heat dissipation method cannot meet the requirements of the current products. Therefore, our engineers abandon the traditional air-cooling heat dissipation method and then use a novel cold plate heat dissipation method. The cold plate heat dissipation system generally comprises a water cooling plate, a circulating liquid pump pipeline and a heat exchanger, wherein each part has a unique function, for example, a liquid cooling plate radiator is an internal water channel radiator made of aluminum or copper-aluminum composite, circulating liquid flows in a pipeline in a circulating mode under the action of a water pump, when the liquid absorbs heat of a device, the liquid flows away from a water cooling block on the device, and new low-temperature circulating liquid continuously absorbs the heat of the device.
After the Delta GPU board published by Nvidia, the traditional air-cooled heat dissipation still cannot meet the heat dissipation requirement of a single 500W GPU on the Delta board when the traditional air-cooled heat dissipation reaches the limit design, and the heat dissipation problem of 8 GPUs on the whole board GPU board is not considered. The problems of difficult installation and positioning, complex operation, labor and labor waste and low working efficiency exist in the fixation of a cold plate radiator of an Nvidia Delta GPU plate. The main reasons are the following: the Delta GPU board is a whole PCB, and 8GPU chips and 6 NV switch chips are uniformly arranged on the PCB. Firstly, after various devices are welded on a PCB, the PCB can deform to different degrees; in addition, each GPU chip and NV switch chip may have manufacturing-related dimensional errors. The heights of each GPU chip and SWITCH chip will vary, i.e. not on the same plane. So our cold plate whole plate heat spreader has no way to use one whole cold plate heat spreader to fit GPU chips of different heights and switch chips. Secondly, the devices such as the GPU chip and the switch chip have higher requirements on installation precision and are extremely sensitive to the contact between the bottom of the radiator and the chip. And the heat dissipation margin of the high-power consumption chip is not much. Once the contact is slightly poor, the temperature rise of the chip is greatly changed, and then the packet loss of data or signals is caused.
