Description

Technical Field

[0001] This utility model relates to a water cooling device, and more particularly to a short-flow-path water cooling head device. Background Technology

[0002] Existing water cooling blocks are generally mounted on a heat source to absorb heat. A water cooling block typically includes a chamber where the working fluid is injected and exchanges heat through fins or meandering channels before exiting the chamber to dissipate heat. In these existing cooling methods, the working fluid heats up as it stays in the chamber, reducing the temperature difference between the fluid and the water cooling block, thus decreasing heat exchange efficiency. Therefore, the heat exchange efficiency varies across different parts of existing water cooling blocks, making it difficult to achieve optimal overall cooling efficiency.

[0003] In view of this, the creator has devoted himself to studying the aforementioned existing technologies and applying theoretical principles to try his best to solve the above-mentioned problems, which has become the creator's goal for improvement. Utility Model Content

[0005] This utility model provides a water-cooled head device, which includes a housing, a partition plate, and a partition wall. The housing has an inlet and an outlet. The partition plate is disposed inside the housing, dividing the internal space of the housing into a heat exchange chamber and an inlet / outlet chamber. The partition plate has at least one water inlet and at least one water outlet. The partition wall is disposed inside the inlet / outlet chamber, dividing the inlet / outlet chamber into an inlet water chamber and an outlet water chamber, and the partition wall separates the at least one inlet water outlet and the at least one outlet water outlet. The inlet water chamber is connected to the inlet and communicates with the heat exchange chamber through the at least one inlet water outlet, and the outlet water chamber is connected to the outlet and communicates with the heat exchange chamber through the at least one outlet water outlet.

[0006] In one embodiment of this utility model, there are several inlet ports and several outlet ports. The inlet ports are arranged along several first columns, and the outlet ports are arranged along several second columns.

[0033] See Figures 1 to 3 The first embodiment of this utility model provides a water-cooling head device, which includes a housing 100, a partition plate 200, and a partition wall 300. The housing 100 is provided with an inlet 111 and an outlet 112. In this embodiment, the housing 100 includes a relatively closed upper cover 110 and a lower cover 120. The inlet 111 and the outlet 112 are both disposed on the upper cover 110, but this utility model is not limited thereto. The partition plate 200 is disposed inside the housing 100.

[0034] Figure 4 This is a schematic diagram of the partition plate 200 and partition wall 300 of the water-cooled head device according to the first embodiment of this utility model. (See attached diagram) Figure 4 In this embodiment, the partition wall 300 is integrally formed on one side of the partition plate 200. Figure 5This is a schematic diagram of the partition plate 200 and the support structure 400 of the water-cooled head device according to the first embodiment of this utility model. (See attached diagram) Figure 5 The support structure 400 is integrally formed on the other side of the partition plate 200. (See also...) Figures 3 to 5 The partition plate 200 is provided with at least one water inlet 210 and at least one water outlet 220. In this embodiment, the at least one water inlet 210 includes several water inlets 210, and the at least one water outlet 220 includes several water outlets 220. Furthermore, both the water inlets 210 and the water outlets 220 are perforated. (See reference...) Figures 4 to 5 Specifically, the inlet ports 210 are arranged along several first columns 201, and the outlet ports 220 are arranged along several second columns 202. The first columns 201 and the second columns 202 are arranged side by side and interspersed.

[0035] Figure 6 This is an elevation sectional view of the water-cooled head device according to the first embodiment of this utility model. Figure 7 This is a cross-sectional view of the water-cooling head device according to the first embodiment of this utility model. (See also...) Figure 6 The partition plate 200 divides the internal space of the outer shell 100 into a heat exchange layer cavity 130 and an inlet / outlet cavity 140, and a groove 121 is provided on an outer surface (i.e., the bottom surface) of the outer shell 100 corresponding to the heat exchange layer cavity 130. The support structure 400 is disposed within the heat exchange layer cavity 130 and is connected between the partition plate 200 and the inner wall of the outer shell 100.

[0036] See Figure 1 and Figure 2 A partition wall 300 is disposed within the inlet / outlet cavity 140. The top and bottom edges of the partition wall 300 are respectively connected to the inner wall of the outer shell 100 and the partition plate 200. Specifically, the top edge of the partition wall 300 is connected to the upper cover 110 of the outer shell, and the bottom edge of the partition wall 300 is connected to the partition plate 200. A first sidewall 101 and a second sidewall 102 are respectively provided on two opposite sides of the outer shell 100. Specifically, both the first sidewall 101 and the second sidewall 102 are defined on the lower cover 120, and a groove 121 is also provided on the lower cover 120. The two ends of the partition wall 300 are respectively connected to the first sidewall 101 and the second sidewall 102, and the partition wall 300 extends in a tortuous manner between the first sidewall 101 and the second sidewall 102.

[0037] Thus, the partition wall 300 divides the inlet / outlet cavity 140 into an inlet water cavity 141 and an outlet water cavity 142. The partition wall 300 separates the water inlet port 210 on the partition plate 200 into the inlet water cavity 141, and the water outlet port 220 on the partition plate 200 into the outlet water cavity 142. The inlet water cavity 141 is connected to the heat exchange cavity 130 through the water inlet port 210, and the outlet water cavity 142 is connected to the heat exchange cavity 130 through the water outlet port 222.

[0038] Figure 7 This is a cross-sectional view of the water-cooling head device according to the first embodiment of this utility model. (See also...) Figure 6 and Figure 7 The water-cooling head assembly is attached to a circuit board 11, which has a heat source 12, such as an electronic component attached to the circuit board 11. The heat source 12 is attached to the housing 100 and housed in a groove 121 on the outer surface of the housing 100. Specifically, the working fluid is injected into the water inlet chamber 141 from the inlet 111 and guided longitudinally into each of the first columns 201 by the partition wall 300. The working fluid enters the heat exchange layer chamber 130 through the water inlet 210. After entering the heat exchange layer chamber 130, the working fluid directly impacts the inner surface of the bottom of the housing 100 and absorbs heat energy from the heat source 12. After impacting the inner surface of the bottom of the housing 100, the working fluid reverses and enters laterally into at least one adjacent second column 202. The working fluid enters the water outlet chamber 142 through the water outlet 220 and is then discharged through the outlet 112.

[0039] The above structure allows the working fluid to flow directly to the heat source 12 after entering the heat exchange chamber 130 and then be discharged in reverse after heat exchange. Therefore, the working fluid flows in the heat exchange chamber 130 with a shorter path to maintain a larger temperature difference with the heat source 12, and can shorten the residence time of the working fluid in each part of the heat exchange chamber 130 to achieve the effect of uniform temperature.

In this embodiment, the housing 100 includes a relatively closed upper cover 110 and a lower cover 120, with both the inlet 111 and outlet 112 disposed on the upper cover 110; however, this utility model is not limited to this. The partition plate 200 is disposed within the housing 100. In this embodiment, the combination of the housing 100, the partition plate 200, and the partition wall 300 still defines a water-cooling head device.
