Description

TECHNICAL FIELD

[0001] The present application relates to the field of liquid cooling radiator, and particularly relates to a double-pump double-circulation integrated liquid cooling radiator for cooling a processor. BACKGROUND

[0002] There are two types of heat sinks for computer processors, air cooling heat sink and liquid cooling heat sink. The liquid cooling head of the liquid cooling heat sink is attached to the surface of the processor, and the heat generated by the processor during operation is removed through the flow of cold liquid through the liquid cooling head. The heated liquid is then flowed to the radiator, and the heat is dissipated through the radiator to cool the liquid, which is then returned to the liquid cooling head. In this way, the cooling and heat dissipation efficiency of the liquid cooling heat sink is higher than that of the traditional air cooling heat sink. There are many types of conventional liquid cooling heat sinks, one of which is an integrated liquid cooling heat sink with the advantages of small size and easy installation. For example, in the prior art, a pump is provided in the liquid box of the radiator, and the lower end of the radiator is provided with a liquid cooling head. When the integrated liquid cooling heat sink is installed, the liquid cooling head is attached to the surface of the processor, and the internal liquid is circulated through the liquid cooling head by the pump to achieve the function of cooling and dissipating heat of the processor.

[0003] The operation of the liquid cooling heat sink relies on the pump to drive the circulation of the liquid through the liquid cooling head to cool the processor and bring the heated liquid to the radiator for heat dissipation. If the pump slows down due to aging, the cooling and heat dissipation efficiency will be reduced, but the user cannot detect it. In particular, when the pump fails completely, the entire liquid cooling heat sink cannot operate, resulting in the user's computer being unable to boot up. Therefore, how to make the liquid cooling heat sink continue to operate even if one of the pumps is aging or fails, so as to avoid inconvenience to the user or computer failure, is a problem to be actively overcome by the present application.

Through the double-circulation flow channel structure of the radiator of the integrated liquid cooling heat sink and the flow channel structure design inside the liquid cooling head, two pumps can be installed in the integrated liquid cooling heat sink. The two pumps independently drive the circulation of the liquid in the double-circulation flow channels of the radiator, and the liquid flows into the internal flow channel of the liquid cooling head and mixes together. In this way, even if one of the pumps is aging or fails completely, the other pump can still make the integrated liquid cooling heat sink continue to operate.

The first pipes 31 and the second pipes 32 have a rectangular cross section corresponding to the pipe insertion holes 171 and 271, or can have a circular or elliptical cross section.

[0092] Referring to Figure 4 to Figure 7 As shown, the two liquid pumps 40 are installed in the liquid pump chambers 161 of the two first chambers 12 of the heat dissipation pipe group 100, so that the two liquid pumps 40 are used to independently circulate the liquid in the two liquid circulation systems of the heat dissipation pipe group 100. The specific flow circuit is shown in Figure 12 As shown, the cold liquid flowing through the liquid cooling head 50 is cooled to become hot liquid, which flows into the two hot liquid chambers 24 of the second liquid box 20, and then flows to the two liquid inlet chambers 14 of the first liquid box 10 through the plurality of first pipes 31.

[0093] Referring to Figure 7As shown, the preferred embodiment of the liquid pump 40 has a liquid pump housing 41, a stator 42 and a rotor 43. The liquid pump housing 41 has an end cap 411 which is screwed to a groove 19 on the outside of the first liquid box 10 so that the end cap 411 of the liquid pump housing 41 closes the liquid pump cavity 161.

[0094] Referring to Figure 9 to Figure 11 As shown, the liquid cooling head 50 is used to contact the processor for cooling and has a liquid cooling head body 51 and a heat dissipation base 52. The liquid cooling head body 51 is fixed to the bottom surface of the second liquid box 20 by screws. The bottom surface of the liquid cooling head body 51 is provided with a liquid cavity 511 which is concave upward and two second cold liquid inlets 512 which respectively communicate with the two first cold liquid inlets 251 and two second hot liquid outlets 513 which respectively communicate with the two first hot liquid outlets 241. The heat dissipation base 52 has a bottom plate 521 and a plurality of micro water channels 522 which are formed on the top surface of the bottom plate 521. The bottom plate 521 is screwed to the bottom surface of the liquid cooling head body 51 and seals the liquid cavity 511 so that the micro water channels 522 are located in the liquid cavity 511 and the cold liquid can flow through the micro water channels 522 for balanced cooling (heat exchange).

[0095] The preferred embodiment of the liquid cooling head 50 further includes a liquid partition plate 53 which is arranged in the liquid cavity 511 of the liquid cooling head body 51. The liquid partition plate 53 is provided with a strip-shaped through hole 531 in the middle and on both sides. The flow direction of the micro water channels 522 is perpendicular to the strip-shaped through hole 531 so that the cold liquid flows into the center of the micro water channels 522 through the strip-shaped through hole 531 in the middle of the liquid partition plate 53 and then flows to both sides of the strip-shaped through hole 531 on both sides of the liquid partition plate 53 through the micro water channels 522, thereby achieving the effect of sufficient and balanced cooling of the heat dissipation base 52. The top wall of the liquid cavity 511 of the liquid cooling head body 51 has a protrusion 514 which is concave downward and has a strip-shaped groove 515 which is concave upward.

A ring-shaped flow channel 516 is formed between the protrusion 514 and the inner wall of the liquid cavity 511. The two second hot liquid outlets 513 respectively communicate with the ring-shaped flow channel 516.

[0096] Referring toFigure 4 and Figure 12 As shown, when the liquid flows, the cold liquid in the two cold liquid chambers 25 of the second liquid box 20 enters the liquid chamber 511 of the liquid cooling head 50 through the first cold liquid inlet 251 and the second cold liquid inlet 512, respectively. The cold liquid then flows through the strip-shaped through-hole 531 and the strip-shaped through-hole 531 in the middle of the liquid baffle 53 to the numerous microchannels 522 on the heat sink 52, which are used to cool the processor (heat exchange) and become hot liquid. See also Figure 13 As shown, the hydrothermal fluid flows into the surrounding annular flow channel 516, then through two second hydrothermal outlets 513 to the hydrothermal chambers 24 of the second liquid box 20, then through the aforementioned plurality of first row pipes 31 to the first liquid box 10, and then through the plurality of second row pipes 32 back to the two cold liquid chambers 25 of the second liquid box 20 (e.g., Figure 4 and Figure 12 As shown in the figure, this completes a cooling and heat dissipation cycle.

[0097] Additionally, please refer to Figure 1 to Figure 3 As shown, two outer frames 60 are provided between the first liquid box 10 and the second liquid box 20 of the heat dissipation pipe 100. The two outer frames 60 are located on both sides of the pipe assembly 30, so that a fan 70 can be locked between the two outer frames 60 on the front and rear sides of the heat dissipation pipe 100 respectively. The fan 70 blows air through the pipe assembly 30, so that the air flowing through the first pipe 31 and the second pipe 32 can dissipate heat quickly.

[0098] In use, this invention employs a dual-liquid pump and dual-liquid circulation system design. Two liquid pumps 40 drive the liquid in each of the two liquid circulation systems of the heat sink 100 to circulate into the liquid cooling head 50. Therefore, even if one liquid pump 40 ages and its operating speed decreases or it malfunctions, the liquid can still circulate to the liquid cooling head 50 through the liquid cooling system of the other liquid pump 40, ensuring that the liquid cooler can perform both cooling and heat dissipation functions. Furthermore, through the flow channel structure design of the microchannels 522, the strip-shaped through-holes 531 of the baffle plate 53, and the annular flow channel 516 inside the liquid cooling head 50, this invention allows the liquid in the dual-liquid circulation system within the heat sink 100 to flow into the liquid cooling head 50 and fill the entire microchannel 522, achieving the goal that both liquid pumps 40's liquid circulation systems have the function of cooling and heat dissipating the processor. Furthermore, the present invention is a dual-liquid pump and dual-liquid circulation system, which can increase the flow rate of liquid through the liquid cooling head 50, and can effectively solve the cooling efficiency required when the processor is overclocked or operating at high speed.

[0099] In summary, the double liquid pump double circulation integrated liquid cooling radiator of the present application has practicality and creativity, the use of technical means is undoubtedly new, and the function and design purpose are indeed consistent, which is a reasonable progress. Therefore, an invention patent application is proposed according to the law, and the bureau is sincerely requested to examine in detail and grant a patent, which is grateful.
