Abstract

This utility model discloses a water-cooled head with an interlaced fin structure, comprising a shell, first fins, second fins, a fluid inlet, and a fluid outlet. The shell includes a lower shell base and an upper shell cover that is tightly sealed to the lower shell base, forming a cavity between the lower shell base and the upper shell cover. The first fins extend from the lower shell base and are located within the cavity, with a first fluid channel formed between any two adjacent first fins. The second fins extend from the upper shell cover and are located within the cavity, with a second fluid channel formed between any two adjacent second fins, wherein each second fin is interlaced with each first fin. The fluid inlet is located on the upper shell cover and communicates with the cavity; the fluid outlet is located on the upper shell cover and communicates with the cavity. This eliminates the gap between the boundaries of the lower shell base and the upper shell cover, thereby reducing fluid backflow and resisting pressure from fin bending deformation.

Description

Technical Field

[0001] This utility model relates to the technical field of a water cooling head, and more particularly to a water cooling head with an interlaced fin structure. Background Technology

[0002] With the development and progress of technology, heat dissipation devices using aluminum extruded fins, fins combined with fans, or fins combined with heat spreaders and fans can no longer meet the heat dissipation needs of products in different stages. As the efficiency of existing electronic heat sources continues to improve, the heat they generate also continues to increase. If this heat cannot be effectively dissipated and accumulates on the electronic heat source, it may be damaged due to the continuously rising temperature.

[0003] To address the aforementioned issues, manufacturers have developed various water-cooled heat dissipation devices with different performance levels. These devices are mainly composed of multiple pipes, water cooling heads, and pumps, or are formed by connecting cooling modules (such as water cooling radiators) in series. Among these, the method of contacting the water cooling head with the electronic heat source to help dissipate heat from the electronic heat source is the most widespread.

[0004] The water cooling head mainly includes a lower housing and an upper housing that is tightly sealed to the corresponding lower housing. A fluid cavity is formed between the lower housing and the upper housing. A plurality of fins are arranged in the fluid cavity, and a fluid channel is formed between any two adjacent fins.

[0005] However, while existing water cooling blocks have good heat conduction and heat dissipation performance, they have the following problems that need to be solved in actual use. Because the thickness of each fin is quite thin, they are very easy to deform under pressure during the assembly process, which will cause a gap or gap between the upper end face and the inner surface of the upper shell. Such gaps or gaps will cause various adverse conditions such as backflow or turbulence of the fluid entering the fluid cavity, thereby reducing its heat conduction and heat dissipation performance. Utility Model Content

[0011] In some embodiments, the upper shell is provided with a stepped groove formed around each of the second fins, and the lower shell seat is embedded in the stepped groove.

[0012] In some embodiments, an annular flow channel is formed between the outer periphery of each of the first fins and each of the second fins and the stepped groove, the annular flow channel being in communication with each of the first fluid channels and each of the second fluid channels, and the fluid outlet being formed in the annular flow channel.

[0013] In some embodiments, each of the first fluid channels is parallel to each other, each of the second fluid channels is parallel to each other, and each of the first fluid channels and each of the second fluid channels is orthogonally configured.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Please see Figures 1 to 4As shown, this utility model provides a water cooling head with an interlaced fin structure, which mainly includes a shell 10, a plurality of (two or more) first fins 20, a plurality of second fins 30, a fluid inlet 40 and a fluid outlet 50.

[0026] The housing 10 mainly includes a lower housing seat 11 and an upper housing cover 12. The lower housing seat 11 and the upper housing cover 12 are made of materials with good thermal conductivity, such as copper, aluminum, magnesium or their alloys. The upper housing cover 12 is in close contact with and sealed to the lower housing seat 11, so as to form a fluid cavity A between the lower housing seat 11 and the upper housing cover 12.

[0027] Each first fin 20 extends upward from the inner surface of the lower housing 11 and is located in the fluid cavity A. A first fluid channel 21 is formed between any two adjacent first fins 20. Each first fin 20 is parallel to each other, and each first fluid channel 21 is also parallel to each other.

[0028] Each second fin 30 extends downward from the inner surface of the upper shell 12 and is located in the fluid cavity A. A second fluid channel 31 is formed between any two adjacent second fins 30. The second fins 30 are parallel to each other, and the second fluid channels 31 are also parallel to each other. The second fins 30 and the first fins 20 are staggered. In this embodiment, the second fins 30 and the first fins 20 are orthogonally arranged. Similarly, the first fluid channels 21 and the second fluid channels 31 are also orthogonally arranged.

[0029] The fluid inlet 40 is located in the middle of the upper shell 12 and is connected to the aforementioned fluid cavity A.

[0030] The fluid outlet 50 is located at the periphery of the upper housing 12 and is connected to the aforementioned fluid cavity A.

[0031] In one embodiment, the height H1 of each first fin 20 is greater than the height H2 of each second fin 30, and the end face of each first fin 20 is in close contact with and tightly joined to the end face of each second fin 30.

[0032] In one embodiment, the water cooling head of the present invention has an interlaced fin structure and further includes a first connector 60, which is connected to the aforementioned fluid inlet 40.

[0033] In one embodiment, the water cooling head of the present invention has an interlaced fin structure and further includes a second connector 70, which is connected to the aforementioned fluid outlet 50.

[0034] In one embodiment, the upper shell 12 is provided with a stepped groove 121, which is formed in the outer periphery of each second fin 30, and the lower shell seat 11 is embedded in the stepped groove 121. Furthermore, an annular flow channel B is formed between the outer periphery of each first fin 20 and each second fin 30 and the stepped groove 121. This annular flow channel B is interconnected with the aforementioned first fluid channels 21 and each second fluid channel 31, and the aforementioned fluid outlet 50 is formed in the annular flow channel B.

[0035] In use, the working fluid is injected through the first connector 60 and enters the fluid cavity A through the fluid inlet 40. Since the end faces of each first fin 20 and each second fin 30 are in contact, there are no gaps or gaps between their boundaries. Therefore, the working fluid can smoothly and quickly enter each first fluid channel 21 and each second fluid channel 31, and carry away the heat of each first fin 20 and each second fin 30. Then, it is quickly output from the second connector 70 through the fluid outlet 50, thereby improving the heat conduction and heat dissipation efficiency of the water cooling head.

[0036] Please see Figure 5 As shown, the water cooling head with an interlaced fin structure of this utility model, in addition to the above embodiments, differs from the aforementioned upper shell 12A in that the second fins 30 formed on the upper shell 12A are arranged at an angle, thereby making the first fins 20 and the second fins 30 obliquely intersecting, thus achieving the same effect as the aforementioned embodiments. Similarly, the first fluid channels 21 and the second fluid channels 31 are also obliquely intersecting. As for the lower shell 11, second fins 30, second fluid channels 31, fluid inlet 40, fluid outlet 50, first connector 60, second connector 70, fluid cavity A, and annular flow channel B in the aforementioned embodiments, they are the same as the relevant components in this embodiment, and therefore will not be described again.

[0037] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model, or reasonable combinations of features and solutions from various embodiments, are all within the protection scope of the present utility model.
