Description

Technical Field

[0001] The utility model relates to the technical field of water cooling, and in particular to a water cooling module that improves heat exchange efficiency. Background Art

[0002] Water-cooling modules use a continuous, variable flow of cooling water to remove heat from objects in contact with the module, preventing them from being damaged by overheating. Current water-cooling modules typically have winding channels, increasing the water flow path and improving heat exchange efficiency. However, this structure is typically used for larger water-cooling modules. For smaller modules, adding more winding channels would require reducing the channel width, which would in turn reduce water flow and affect heat exchange efficiency. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a water cooling module that improves the heat exchange efficiency. By modifying the flow channel structure, a wider flow channel can also have sufficient heat exchange efficiency.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The utility model provides a water-cooling module for improving heat exchange efficiency, comprising a shell, a water inlet, and a water outlet. The shell is provided with a flow channel structure, which is respectively connected to the water inlet and the water outlet. The flow channel structure includes a connecting portion and two flow channels. The flow channels include an external connection portion and a plurality of widening portions. The plurality of widening portions are arranged in sequence, and a connecting portion is provided between adjacent widening portions. The widening portion at one end is connected to the water inlet and the water outlet through the connecting portion, and the widening portion at the other end is connected to the connecting portion.

[0006] A block is provided in the widened portion, and the block is used to force water in the flow channel to flow through the space between the widened portion and the block, and the width of the widened portion is greater than the width of the connecting portion.

[0007] Furthermore, the stopper is an arc-shaped structure, and the middle portion of the stopper faces one end of the widened portion where water flows into;

[0008] The width of the widened portion gradually increases from one end where water flows into the widened portion to the other end.

[0009] Furthermore, arc-shaped inner side walls are provided on both sides of the widened portion corresponding to the stopper.

[0010] Furthermore, the bottom height of the end of the external connection portion connected to the water inlet / outlet is lower than the bottom height of the end of the external connection portion connected to the widened portion;

[0011] A drainage slope is provided between the two ends of the external connection part.

[0012] Furthermore, the stopper is integrally formed with the housing.

[0013] Furthermore, the shell is provided with a heat dissipation groove, and the flow channel structure is located in the heat dissipation groove; the shell is welded with a top cover for covering the heat dissipation groove, and the top cover is in conflict with the stopper.

[0014] Furthermore, the width of one end of the heat dissipation slot close to the water inlet and the water outlet is smaller than the width of the other end, and the shape of the top cover is adapted to the shape of the heat dissipation slot.

[0015] The beneficial effects of the present invention are as follows: the present invention improves the efficiency of heat exchange by setting the widened portion and the block, that is, when water flows to the block, the block forces the water to split into two streams, flowing from both sides of the widened portion and merging at the other end of the widened portion, thereby changing the water flow path.

DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0020] like Figure 1 and Figure 2 As shown, the utility model provides a water-cooling module for improving heat exchange efficiency, including a shell 1, a water inlet 2 and a water outlet 3. The shell 1 is provided with a flow channel structure 4, which is respectively connected to the water inlet 2 and the water outlet 3. The flow channel structure 4 includes a connecting portion 5 and two flow channels 6. The flow channel 6 includes an external portion 61 and a plurality of widening portions 62. The plurality of widening portions 62 are arranged in sequence, and a connecting portion 63 is provided between adjacent widening portions 62. The widening portion 62 at one end is connected to the water inlet 2\water outlet 3 through the connecting portion 5, and the widening portion 62 at the other end is connected to the connecting portion 5.

[0021] A block 64 is provided in the widened portion 62 . The block 64 is used to force the water in the flow channel 6 to flow through the space between the widened portion 62 and the block 64 . The width of the widened portion 62 is greater than the width of the connecting portion 63 .

[0022] That is, water enters the external portion 61 of the flow channel 6 from the water inlet 2, and enters the widened portion 62 after passing through the external portion 61; since there is a block 64 in the widened portion 62, the water is forced to flow to both sides of the widened portion 62, thereby increasing the path of water flowing in the widened portion 62 to achieve the effect of heat exchange for a longer time. At the same time, since the width of the widened portion 62 is greater than the width of the connecting portion 5, the flow rate of water in the widened portion 62 is smaller than the flow rate in the connecting portion 5. Therefore, the water can stay in the widened portion 62 for a longer time to carry out heat exchange, further improving the efficiency of heat exchange.

[0023] In this embodiment, the stopper 64 is an arc-shaped structure, and the middle portion of the stopper 64 faces one end of the water-inflow widened portion 62;

[0024] The width of the widened portion 62 gradually increases from one end where water flows into the widened portion 62 to the other end.

[0025] The stopper 64 is an arc-shaped structure, with the middle portion of the arc pointing in the direction of water inflow from the widened portion 62. That is, the widened portions 62 of the two flow channels 6 are oriented 180 degrees opposite to each other. This structure allows the arc-shaped structure of the stopper 64 to guide water flow in both directions, preventing water from being retained by the stopper 64. This prevents untimely water flow and the resulting excessive water pressure in certain areas within the utility model.

[0026] Specifically, the widened portion 62 is provided with arc-shaped inner side walls 65 on both sides corresponding to the block 64, so that the shape of the widened portion 62 is similar to the shape of a heart, that is, the flow rate of water will decrease as it enters the widened portion 62 until it is guided by the block 64 and stopped by the block 64, causing the flow rate to increase again, thereby achieving the effect of controlling the variable speed flow of water and making the heat exchange efficient.

[0027] In this embodiment, the bottom height of the end of the external connection portion 61 communicating with the water inlet 2 / water outlet 3 is lower than the bottom height of the end of the external connection portion 61 communicating with the widened portion 62;

[0028] A drainage slope 66 is provided between the two ends of the external connection portion 61 .

[0029] That is, there is a height difference between the two ends of the external connecting portion 61, so that after water enters the external connecting portion 61, the flow rate increases as the volume of the path becomes smaller, realizing a gradual speed-increasing process, thereby preventing the water from flowing too fast at the beginning and causing deformation of the block 64 in the widened portion 62 connected to the external connecting portion 61.

[0030] In this embodiment, the stopper 64 is integrally formed with the housing 1 , which makes the structure of the present invention more stable and the stopper 64 less likely to fall off, thereby ensuring the effect of guiding the flow of water.

[0031] In this embodiment, the housing 1 is provided with a heat dissipation slot 11 , and the flow channel structure 4 is located in the heat dissipation slot 11 ; a top cover 7 for covering the heat dissipation slot 11 is welded to the housing 1 , and the top cover 7 abuts against the stopper 64 .

[0032] In actual use, the width of the heat dissipation slot 11 near the water inlet 2 and the water outlet 3 is smaller than that of the other end. In this embodiment, the shape of the top cover 7 is adapted to the shape of the heat dissipation slot 11.

[0033] That is, the flow channel structure 4 is formed in the heat dissipation groove 11 by CNC or laser welding, and then the top cover 7 is covered on the heat dissipation groove 11, and then a fixed connection between the two is achieved by welding, thereby preventing the top cover 7 from being separated from the shell 1, and also ensuring the sealing of the utility model to avoid water leakage.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
