Description

[Technical field]

[0001] The present invention relates to a liquid cooling and heat dissipation device, and more particularly to a dual liquid pump liquid cooling and heat dissipation device for use in servers to cool processors. [Background technology]

[0002] Conventional server processors emit heat during operation, so a liquid cooling system with better cooling effect must be used. A known liquid cooling system (for example, according to Patent Document 1) is a closed liquid circulation system that combines a liquid cooling head, a radiator, a liquid port, and liquid tubes connecting the liquid cooling head, the radiator, and a liquid pump, and has a diversion box on the radiator, a return box, a heat dissipation radiator connected between the diversion box and the return box, and heat dissipation fins, and generally, the inside of the diversion box is divided into a heat liquid chamber and a cooling liquid chamber by a metal partition plate.

[0003] [Patent Document 1] US Patent Publication No. US20090044929 Summary of the Invention [Problem to be solved by the invention]

[0004] The radiator tube of the above-mentioned known liquid cooling radiator is short, and only one liquid pump can flow the liquid therein. However, because the heat dissipating radiator tube is short, the liquid cannot be lowered to a desired low temperature after it flows into the radiator tube. If it is returned to the liquid cooling head, problems remain such as a decrease in cooling efficiency and heat accumulation in the liquid. To solve this problem, in addition to lengthening the radiator tube and heat dissipating fins, the number of fans is increased, so that the liquid flows longer inside the radiator tube to lower the temperature. However, this approach may result in an insufficient amount of liquid cooling inside the radiator tube, which may result in overloading of any one of the liquid ports in the liquid cooling radiator.

[0005] In addition, the hot liquid is transferred to the cooling liquid in the cooling chamber through the metal partition plate in the hot liquid chamber, resulting in the cooling liquid being heated after cooling. Meanwhile, since the space between the hot liquid chamber and the cooling liquid chamber in the prior art is the same, the hot liquid cannot pass through the hot liquid chamber quickly and flow to the heat dissipation radiator, so the thermal energy of the hot liquid is accumulated in the shunt box and transferred to the front of the cooling radiator (including the front of the heat dissipation radiator), causing the cooling liquid to be heated again after heat dissipation. [Means for solving the problem]

[0006] The present invention has been made in view of the above, and has an object to provide a dual liquid pump radiator and a liquid cooling heat dissipation device. The dual liquid pump radiator includes a first liquid box, a second liquid box, and a first radiator tube set and a second radiator tube set connected between the first liquid box and the second liquid box, and the first liquid box and the second liquid box each have a liquid port portion provided inside, so that the liquid port portions of the first liquid box and the second liquid box flow the working liquid and dissipate heat.

[0007] The objective of the present invention is to provide a dual fluid pump liquid cooling heat dissipation device radiator and a liquid cooling heat dissipation device, in which the air-blocking space inside the first liquid box of the dual fluid pump radiator is designed so that the heat liquid flowing into the first liquid box cannot be transferred to the cooling liquid that has already dissipated heat.

[0008] Another object of the present invention is to provide a dual fluid pump liquid cooling heat dissipation device radiator and a liquid cooling heat dissipation device, in which the spatial design of the first liquid box of the dual fluid pump radiator allows the hot liquid flowing into the first liquid box to flow quickly to the first radiator tube group. Effect of the Invention

[0009] (1) The dual liquid pump liquid cooling and heat dissipation device of the present invention improves the overall heat dissipation effect by increasing the total length of the first radiator tube set and the second radiator tube set and the number of fans, and avoids the flow rate reduction and excessive load on a single liquid pump caused by the first radiator tube set and the second radiator tube set being too long.

[0010] The air-blocking space of the present invention prevents the hot liquid in the hot liquid chamber from being transferred to the cooling liquid in the cooling liquid chamber, prevents the cooled cooling liquid from being reheated, and improves the cooling effect of the liquid cooling head.

[0011] (2) The dual fluid pump liquid cooling and heat dissipation device of the present invention can prevent the thermal energy of the heating fluid from being transferred to the cooling fluid, preventing the cooling fluid from being heated again, and improving the cooling effect of the entire liquid cooling and heat dissipation device on the processor.

[0012] (3) The dual fluid pump liquid cooling heat dissipation device of the present invention allows the hot liquid flowing into the first liquid box to quickly flow into the first radiator tube group to dissipate heat, thereby avoiding the heat accumulation phenomenon caused by the hot liquid stagnation in the first liquid box.

A first liquid pump 50 is provided inside the first hot liquid chamber 12 or the first cooling liquid chamber 13 of the first liquid box 10, and when the first liquid pump 50 is operated, it flows the cooling liquid (hot liquid) that has been heated inside the liquid cooling head 200 through one of the liquid tubes 300 and the liquid inlet hole 14 into the first hot liquid chamber 12, and then again into the flat tubes 31 of the first radiator tube set 30, and from each flat tube 31 to the second liquid box 20. In this process, the first radiator tube group 30 is used to dissipate heat for the first time to lower the temperature, and when the first liquid pump 50 is operated, the cooling liquid inside the second liquid box 20 flows through the flat tube 41 of the second radiator tube group 40 to the first cooling liquid chamber 13, and then the second radiator tube group 40 is used to dissipate heat for the second time to lower the temperature, and the cooling liquid (cooling liquid) that has dissipated heat and lowered the temperature is transported again through the liquid outlet hole 15 and another liquid tube 300 to the liquid cooling head 200, to cool the processor 500 again.

The second liquid box 20 is a hollow sealed metal box, and a second partition plate 21 is provided inside the second liquid box 20, which divides the inside of the second liquid box 20 into a second hot liquid chamber 22 and a second hot liquid chamber 23. A second liquid pump 60 is provided inside the second liquid chamber 22 or the second cooling liquid chamber 23, and the second liquid pump 60 operates to flow the cooling liquid (the hot liquid whose temperature has been lowered the first time) inside the flat tubes 31 of the first radiator tube set 30 into the second hot liquid chamber 22, and the cooling liquid in the second cooling liquid chamber 23 into the flat tubes 41 of the second radiator tube set 40, and then the second radiator tube set 40 is used to dissipate heat a second time, lower the temperature, and turn the liquid into cooling liquid, which then flows into the first cooling chamber 13 of the first liquid box 10. In an embodiment of the present invention, by using the first liquid pump 50 and the second liquid pump 60 to operate simultaneously, the flow rate reduction and excessive liquid pump load that occur after the radiator tube set is lengthened can be overcome, and the lengths of the first radiator tube set 30 and the second radiator tube set 40 can be increased, and more fans 80 can be installed in parallel.

Since the thermal conductivity of air is 0.025 W / mK while the thermal conductivity of aluminum is 237 W / mK, the air blocking space 11 of the present invention can effectively prevent the hot liquid in the first cooling liquid chamber 12 from being transferred to the cooling liquid in the first cooling liquid chamber 13 of the partition wall, prevent the cooling liquid from being heated again after its temperature is reduced, and ensure the efficiency of the cooling liquid when it flows into the liquid cooling head 200.
