Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and more specifically to a heat dissipation structure for computing chips. Background Technology

[0002] Current status of heat dissipation technology: (1) Traditional open-type air cooling has a heat density limit of 500W. With the continuous increase in power consumption of computing chips, the traditional fan air cooling technology has reached a bottleneck and can no longer adapt to the higher power consumption conditions. On the other hand, the air will bring in dust, and the accumulation of dust is not conducive to heat dissipation and affects the long service life of the device. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heat dissipation structure for computing chips.

[0004] The technical solution of this utility model is as follows: A heat dissipation structure for computing chips, comprising: Heat sink assembly: includes 3D_VC and heat sink fins. The 3D_VC consists of a VC vapor chamber and multiple heat pipes fixed to the VC vapor chamber. The heat pipes are hollow and their internal chambers are connected to the VC vapor chamber. The multiple heat pipes are respectively embedded in the heat sink fins and welded together. Radiator housing: The radiator assembly is installed inside the radiator housing. Multiple heat-conducting blocks are sealed on the bottom surface of the radiator housing, and the inner surface of the heat-conducting blocks is in close contact with the VC heat spreader. The radiator housing has an opening on its side, and an intake fan and an exhaust fan are installed outside the opening. The intake fan is located next to the heat dissipation fins on one side, and the exhaust fan is located next to the heat dissipation fins on the other side.

[0005] A baffle plate is installed between the air intake fan and the air outlet fan.

[0006] The heat pipe and the VC vapor chamber contain a certain amount of phase change fluid.

[0007] The radiator housing is made of thermally conductive material, and an auxiliary heat pipe is installed between the VC vapor chamber plate and the bottom surface of the radiator housing to enhance heat conduction.

[0008] The radiator housing is equipped with a baffle plate and several air guide mounting columns. The air guide mounting columns are set in the direction of the wind, which can facilitate the smooth flow of air and also serve as mounting columns for the radiator housing cover.

[0009] The technical effects and advantages of this utility model are as follows: The chip is separated from the internal heat dissipation structure. The heat sink in contact with the chip uses air cooling, eliminating the need for air to flow through the chip. This not only effectively dissipates heat from the chip but also prevents dust from accumulating inside the computing device. On the chip heat dissipation side, a combination of 3D_VC and fins is used. 3DVC integrates the base plate and heat pipe, optimizes the circulation efficiency of the phase change fluid, and accelerates the heat transfer to the fins. Setting up deflectors and several air guide columns can improve convective heat dissipation efficiency. Attached Figure Description
