Description
Technical Field
[0001] This invention relates to the technical field of liquid cooling radiators, and more particularly to a liquid cooling box used in liquid cooling radiators, and a dual-liquid pump liquid cooling radiator assembled using the liquid cooling box. Background Technology
[0002] Modern liquid cooling radiators are primarily installed on the processors (CPUs) of desktop computers or servers to cool and dissipate heat from the processor. A typical discrete liquid cooling radiator includes a liquid cooling head mounted on the processor for cooling, a liquid cooling radiator housed within the chassis for heat dissipation, and two liquid tubing connecting the liquid cooling head and the liquid cooling radiator. The circulation of liquid within the liquid cooling head, liquid cooling radiator, and the two liquid tubing effectively cools and dissipates heat from the processor.
[0003] The aforementioned conventional liquid-cooled heatsink consists of a heatsink assembly, a first liquid reservoir, a second liquid reservoir, and a liquid pump. The liquid pump includes a motor and an impeller. The heatsink assembly comprises multiple parallel pipes and heat dissipation fins welded between the pipes, serving as the main component for liquid cooling. The first and second liquid reservoirs are respectively assembled at both ends of the heatsink assembly, with each end of the pipes penetrating into its respective reservoir. The liquid pump is located within the first liquid reservoir, and its motor drives the impeller to rotate. During operation, the hot liquid from the liquid cooling head enters the liquid-cooled heatsink through a liquid pipe, circulates once within the heatsink, and dissipates as cool liquid. The cool liquid then flows through another liquid pipe back to the liquid cooling head to cool the processor.
[0004] However, the first and second liquid boxes in conventional liquid-cooled radiators, being assembled at both ends of the heat dissipation pipe assembly, have different functions and purposes: one primarily allows hot liquid to flow in and cold liquid to flow out, while the other allows liquid to circulate through the heat dissipation pipe assembly. Because the two liquid boxes require different structural designs to provide liquid flow, conventional techniques necessitate the use of two different molds for molding, followed by drilling through-holes to meet their respective functional requirements. This not only increases the complexity and processing time of the manufacturing process but also significantly raises the manufacturing cost of the two liquid boxes, negatively impacting overall product cost control and production efficiency. Therefore, overcoming the shortcomings of the aforementioned conventional techniques is the challenge that this invention aims to address. Summary of the Invention
[0005] The main objective of this invention is to provide a liquid cooling box. Through the structural design of this liquid cooling box, a single mold can be used to form the liquid cooling box blank. Subsequently, by simply changing the direction of the drilling, the liquid cooling box can be manufactured for assembly at both ends of the heat dissipation pipe assembly, thereby simplifying the front-end forming and manufacturing process and reducing costs.
[0006] A secondary objective of this invention is to provide a dual-liquid-pump liquid-cooled radiator, which consists of two liquid-cooled boxes that have been drilled and processed, each assembled with a partition, a cover, and a liquid pump, and then assembled at both ends of a heat dissipation pipe assembly.
[0007] To achieve the above objectives, the present invention proposes a liquid cooling box, the preferred technical solution of which includes: the liquid cooling box is an integrally formed single-opening rectangular box, the liquid cooling box having a back plate and a peripheral side plate surrounding the four sides of the back plate. A partition positioning part is provided in the middle of the inner surface of the back plate and the peripheral side plate for installing a partition to divide the interior of the liquid cooling box into a first liquid chamber and a second liquid chamber. A liquid pump seat is protruding from the inner surface of the back plate corresponding to the first liquid chamber, and a liquid pump cavity is provided on the outer surface of the back plate recessed into the liquid pump seat. The liquid pump cavity has a second liquid inlet hole penetrating the center of the liquid pump seat, allowing the liquid pump cavity to be used to install a liquid pump. A first connecting block protruding from the side of the liquid pump seat and connecting to the inner surface of the peripheral side plate is provided, and a second connecting block protruding laterally from the side of the liquid pump seat is also provided, the end face of the second connecting block extending beyond the middle partition positioning part to the space of the second liquid chamber. A first liquid outlet hole can be drilled in the first connecting block, with one end of the first liquid outlet hole connected to the liquid pump chamber and the other end connected to the outside of the peripheral side plate; or a second liquid outlet hole can be drilled in the second connecting block, with one end of the second liquid outlet hole connected to the liquid pump chamber and the other end connected to the end face of the second connecting block.
[0008] In one preferred technical solution, in the liquid cooling box described above, a first protruding post is provided on the inner surface of the peripheral side plate corresponding to the second liquid chamber. The first protruding post can be drilled with a first liquid inlet hole. One end of the first liquid inlet hole is connected to the second liquid chamber, and the other end is connected to the outside of the peripheral side plate.
[0009] In one preferred technical solution, in the liquid cooling box described above, a second protruding post is provided on the inner surface of the second liquid chamber corresponding to the back plate. The second protruding post can be drilled with a liquid injection hole. One end of the liquid injection hole is connected to the second liquid chamber, and the other end is connected to the outside of the back plate. The liquid injection hole can be screwed with a plug. The plug is used to seal the liquid injection hole after the injected liquid enters the liquid cooling box.
[0010] In one of the preferred technical solutions, in the liquid cooling box described above, the back plate is provided with a number of protruding ribs on the inner surface of the second liquid chamber.
[0011] In one of the preferred technical solutions, in the liquid cooling box described above, the inner surface of the back plate is provided with four third protrusions located around the liquid pump seat, the outer surface of the back plate is provided with a positioning recess, and the bottom surface of the positioning recess is provided with four screw holes extending to the third protrusions.
[0012] In one preferred embodiment, the liquid cooling box further includes a partition and a cover. The partition has a notch corresponding to the cross-sectional outline of the second connecting block. The bottom edge and side edges of the partition are fitted into the partition positioning portion, and the notch is closely fitted to the periphery of the second connecting block. The cover covers the single opening of the liquid cooling box and has multiple pipe insertion holes corresponding to the multiple pipes of the heat dissipation pipe assembly, with the pipe insertion holes penetrating the cover.
[0013] In one preferred embodiment, the liquid cooling box further includes two quick connectors, which are screwed onto the first liquid outlet and the first liquid inlet from the outside of the liquid cooling box, respectively.
[0014] In one preferred embodiment, the liquid cooling box further includes a liquid pump, which is installed into the liquid pump chamber from outside the back plate.
[0015] To achieve the above objectives, the present invention proposes a dual-liquid pump liquid-cooled radiator with a liquid-cooled box, comprising a heat dissipation pipe assembly having a plurality of spaced-apart pipes arranged side by side, and a heat dissipation fin welded between each of the pipes; and two liquid-cooled boxes, wherein the two ends of the pipes are respectively inserted into and welded to the pipe insertion holes of the box cover of the liquid-cooled box.
[0016] In one of the preferred technical solutions, the aforementioned dual-liquid-pump liquid-cooled radiator with a liquid-cooling box further includes two fan brackets, which are welded to both sides of the heat dissipation pipe assembly, and one or more fans are combined on one or both sides of the two fan brackets.
[0017] This invention discloses a liquid cooling box and a dual-liquid-pump liquid-cooled radiator with the liquid cooling box. Through the structural design of the liquid cooling box, a single mold can be used for molding the box. A first connecting block, connected to the inner surface of the peripheral side plate, protrudes from the side of the liquid pump base. A second connecting block, laterally protruding from the side of the liquid pump base, is also formed. Therefore, during subsequent drilling, a first liquid outlet hole can be drilled in the first connecting block of one liquid cooling box, with one end connected to the liquid pump cavity and the other end connected to the outside of the peripheral side plate. A second liquid outlet hole can be drilled in the second connecting block of the other liquid cooling box, with one end connected to the liquid pump cavity and the other end connected to the end face of the second connecting block. Thus, by simply changing the drilling direction, liquid cooling boxes for assembly at both ends of a heat dissipation pipe assembly can be manufactured, simplifying the initial molding and manufacturing process, reducing time, and lowering costs.

[0070] The technical features, structure, method steps, and other functions, purposes, and effects of the present invention will be described in detail below with reference to the accompanying drawings and embodiments:
[0071] See Figure 1 and Figure 2 As shown, the present invention provides a liquid cooling box and a dual-liquid pump liquid cooling radiator with the liquid cooling box. The liquid cooling box 10 is used to assemble with components such as a box cover 30, and then install it at both ends of a heat dissipation pipe assembly 60 to form a dual-liquid pump liquid cooling radiator 100. It can be assembled with existing liquid cooling heads and liquid pipes to form a liquid cooling system for desktop computers or servers.
[0072] See Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the liquid cooling box 10 of the present invention is a single-opening rectangular box integrally formed from aluminum alloy or other metal material. The liquid cooling box 10 has a rectangular back plate 11 and a peripheral side plate 12 surrounding the four sides of the back plate 11. A partition positioning part 13 is provided in the middle of the inner surface of the back plate 11 and the peripheral side plate 12. The partition positioning part 13 includes two positioning protrusions 131 and a positioning groove 132, and extends from the center of the back plate 11 and the inner surface of the peripheral side plate 12, and can be used to install a partition 20 in the positioning groove 132 (e.g., ...). Figure 11 and Figure 14 As shown), the partition positioning part 13 in the middle is used to divide the interior of the liquid cooling box 10 into a first liquid chamber 101 and a second liquid chamber 102.
[0073] See Figure 3 , Figure 7 and Figure 8 As shown, a pump seat 14 protrudes from the inner surface of the back plate 11 corresponding to the first liquid chamber 101, and a pump chamber 141 is recessed into the pump seat 14 on the outer surface of the back plate 11. The pump chamber 141 is provided with a second inlet hole 142 penetrating the center of the pump seat 14, thereby enabling the pump chamber 141 to be used to install a pump 50 (e.g., Figure 11 and Figure 14 As shown), when the liquid pump 50 is running, it draws liquid from the first liquid chamber 101 into the liquid pump chamber 141 through the second liquid inlet 142. See also... Figure 3 and Figure 5 As shown, the present invention is particularly characterized by a first connecting block 15 protruding from the side of the pump base 14 and connected to the inner surface of the peripheral side plate 12, and a second connecting block 16 protruding laterally from the side of the pump base 14. The end face 161 of the second connecting block 16 extends beyond the partition positioning part 13 in the middle to the space of the second liquid chamber 102.
[0074] By means of the above-described structural design of the liquid cooling box 10, after a blank of the liquid cooling box 10 is manufactured using a mold, such as Figure 9 and Figure 10 As shown, a hole is drilled from the outside of the liquid cooling box 10 to drill a first liquid outlet hole 151 in the first connecting block 15. One end of the first liquid outlet hole 151 is connected to the liquid pump chamber 141, and the other end is connected to the outside of the peripheral side plate 12. See also... Figure 12 and Figure 13 As shown, a second liquid outlet hole 162 can be drilled in the second connecting block 16 of another liquid cooling box 10 blank, so that one end of the second liquid outlet hole 162 is connected to the liquid pump chamber 141 and the other end is connected to the end face 161 of the second connecting block 16. In this way, two liquid cooling boxes 10 with the same structure can be selectively drilled with different drilling directions to make liquid cooling boxes that can be installed at both ends of the heat dissipation pipe assembly 60.
[0075] See also Figure 3 , Figure 5 and Figure 8 As shown, in one preferred embodiment of the liquid cooling box 10 described above, a first protrusion 17 is provided on the inner surface of the peripheral side plate 12 corresponding to the second liquid chamber 102. The first protrusion 17 can provide a first liquid inlet hole 171 (e.g., ...). Figure 9 and Figure 11 As shown, the first liquid inlet 171 is connected at one end to the second liquid chamber 102 and at the other end to the outside of the peripheral side plate 12. Furthermore, the back plate 11 has a second protrusion 18 protruding from the inner surface of the second liquid chamber 102. The second protrusion 18 provides a drilling hole 181. One end of the liquid inlet 181 is connected to the second liquid chamber 102 and the other end is connected to the outside of the back plate 11. A plug 40 can be screwed into the liquid inlet 181. The plug 40 can be used to seal the liquid inlet 181 after the liquid is injected into the liquid cooling box 10 when the dual liquid pump liquid cooling radiator 100 is manufactured.
[0076] See also Figure 3 and Figure 5 As shown, the back plate 11 of the liquid cooling box 10 has several protruding ribs 111 on the inner surface corresponding to the second liquid chamber 102, which can be used to improve the structural strength of the liquid cooling box 10. The inner surface of the back plate 11 has four third protruding pillars 19 located around the liquid pump seat, which are also shown in the attached diagram. Figure 4 and Figure 6 As shown, a positioning recess 143 is recessed on the outside of the back plate 11, and the bottom surface of the positioning recess 143 is provided with four screw holes 191 extending to the third protrusion 19, which can be used to lock the liquid pump 50 installed in the liquid pump cavity 141 and the positioning recess 143.
[0077] See Figure 11 and Figure 14As shown, a preferred embodiment of the liquid cooling box 10 of the present invention further includes a partition 20 and a lid 30. The partition 20 has a notch 21 corresponding to the cross-sectional outline of the second connecting block 16, for example, a square notch. The bottom edge and two side edges of the partition 20 are fitted into the partition positioning part 13 of the liquid cooling box 10, so that the notch 21 is in close contact with the periphery of the second connecting block 16. The lid 30 covers the single open end of the liquid cooling box 10. The lid 30 has a plurality of pipe insertion holes 31 corresponding to the plurality of pipes 61 of the heat dissipation pipe assembly 60. The pipe insertion holes 31 penetrate the lid 30 and are used for inserting the pipes 61 for in-furnace welding. In this way, two liquid cooling boxes 10 can be installed at both ends of the heat dissipation pipe assembly 60.
[0078] See also Figure 1 and Figure 11 As shown, after drilling holes for a first liquid outlet 151 and a first liquid inlet 171 in the liquid cooling box 10, a quick connector 70 can be respectively locked or welded to it. The two quick connectors 70 are screwed or welded from the outside of the liquid cooling box 10 to the first liquid outlet 151 and the first liquid inlet 171, respectively. This liquid cooling box 10 with quick connectors 70 can be installed at the first end of the heat dissipation pipe assembly 60, providing conventional liquid pipe connections to each quick connector 70, thereby allowing hot liquid to enter from the first liquid inlet 171, and the cooled liquid, after being cooled by the heat dissipation pipe assembly 60, to flow out from the first liquid outlet 151. See also... Figures 12 to 14 As shown, the other liquid cooling box 10 has a second liquid outlet hole 162 drilled in the second connecting block 16. This liquid cooling box 10 is used to install at the second end of the heat dissipation pipe assembly 60, so that the liquid flows out from the second liquid outlet hole 162 and then flows through the heat dissipation pipe assembly 60 to the direction of the first liquid outlet hole 151.
[0079] See also Figure 1 and Figure 2 As shown, the present invention further proposes a dual-liquid-pump liquid-cooled radiator 100 having the liquid-cooled box 10, which includes a heat dissipation pipe assembly 60. The heat dissipation pipe assembly 60 has a plurality of spaced-apart pipes 61 and a heat dissipation fin 62 welded between each of the pipes 61. Two liquid-cooled boxes 10 are thus positioned at both ends of the heat dissipation pipe assembly 60, with both ends of the pipes 61 respectively inserted into and welded to the pipe insertion holes 31 of the box cover 30 of the liquid-cooled box 10, thereby forming a dual-liquid-pump liquid-cooled radiator 100. Additionally, two fan brackets 80 can be implemented, which are welded to both sides of the heat dissipation pipe assembly 60, and one or more fans 90 are attached to one or both sides of the two fan brackets 80.
[0080] In summary, the liquid cooling box and the dual liquid pump liquid cooling radiator with the liquid cooling box of the present invention are indeed practical and inventive. The application of its technical means is also undoubtedly novel, and its efficacy and design purpose are indeed in line with the present invention. It can be called a reasonable and clear advancement.
