Description

Technical Field

[0001] This utility model relates to the field of water cooling technology, specifically to a side-entry water cooling device. Background Technology

[0002] With the continuous improvement of electronic device performance, especially the widespread application of high-performance computers, servers, graphics cards, and other devices, heat dissipation has become a crucial factor restricting the stability and performance of these devices. Traditional water cooling systems typically consist of components such as cooling fans, radiators, and water blocks. The radiator uses a one-end inlet and one-outlet water design, with coolant flowing from one end of the radiator to the other.

[0003] While this design can meet heat dissipation requirements to some extent, this type of water-cooling radiator has high requirements for installation space and cannot be used in small-space installation scenarios. Although there are some side-inlet / outlet water-cooling radiators, the side-inlet / outlet design can easily lead to uneven flow of coolant in the heat dissipation channels, resulting in poor heat dissipation in some areas and affecting the overall heat dissipation efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a side-entry water cooling heat dissipation device that can achieve side water inlet and outlet while ensuring the heat dissipation efficiency of the water cooling heat dissipation device.

[0005] This utility model is achieved through the following technical solution:

[0006] A side-entry water-cooled heat dissipation device includes a first water chamber, a second water chamber opposite to the first water chamber, and a plurality of heat dissipation channels connecting the first water chamber and the second water chamber. Located outside the heat dissipation channels, an inlet / outlet component, a first water channel communicating with the first water chamber, and a second water channel communicating with the second water chamber are also connected between the first water chamber and the second water chamber. The inlet / outlet component is provided with an inlet communicating with the first water channel and an outlet communicating with the second water channel. A partition is also provided in the first water chamber. When liquid enters the first water chamber from the first water channel, the liquid flows from the side of the first water chamber closest to the first water channel to the other side of the first water chamber under the obstruction of the partition, and then flows in the opposite direction from the other side of the first water chamber to the plurality of heat dissipation channels.

[0007] The partition is disposed in the first water chamber and divides the first water chamber into upper and lower layers. A through hole is provided on the side of the partition away from the first water channel.

[0008] The heat dissipation channel is arranged side by side with the first water channel and the second water channel. The cross-section of the heat dissipation channel is rectangular, and the cross-sectional area of ​​the first water channel and the second water channel is larger than the cross-sectional area of ​​the heat dissipation channel.

[0009] The first waterway and the second waterway are arranged symmetrically with respect to the inlet and outlet water components.

[0010] The inlet and outlet water components, the first water channel, and the second water channel are all externally connected to a cover plate.

[0011] A pressure relief valve is also installed on the side of the first water chamber closest to the first water channel.

[0012] The beneficial effects of this utility model are:

[0013] This utility model discloses a side-entry water-cooled heat dissipation device. By setting a first water channel, an inlet / outlet water assembly, and a second water channel between a first water chamber and a second water chamber, it meets the requirements of side-entry / outlet water dissipation. At the same time, a baffle is set in the first water chamber. When liquid enters the first water chamber from the first water channel, the liquid is blocked by the baffle and flows from the side of the first water chamber closest to the first water channel to the other side of the first water chamber, and then flows in the opposite direction from the other side of the first water chamber to several heat dissipation channels. This achieves uniform flow of coolant in the heat dissipation channels and improves the overall heat dissipation efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] With the continuous improvement of electronic device performance, especially the widespread application of high-performance computers, servers, graphics cards, and other devices, heat dissipation has become a crucial factor restricting the stability and performance of these devices. Traditional water cooling systems typically consist of components such as cooling fans, radiators, and water blocks. The radiator uses a one-end inlet and one-outlet water design, with coolant flowing from one end of the radiator to the other.

[0024] While this design can meet heat dissipation requirements to some extent, this type of water-cooling radiator has high requirements for installation space and cannot be used in small-space installation scenarios. Although there are some side-inlet / outlet water-cooling radiators, the side-inlet / outlet design can easily lead to uneven flow of coolant in the heat dissipation channels, resulting in poor heat dissipation in some areas and affecting the overall heat dissipation efficiency.

[0025] To address the aforementioned problems, this embodiment discloses a side-entry / exit type water-cooling heat dissipation device, the structure of which is as follows: Figures 1 to 3As shown, the heat dissipation device includes a first water chamber 101, a second water chamber 102 disposed opposite to the first water chamber 101, and a plurality of heat dissipation channels 103 connecting the first water chamber 101 and the second water chamber 102. Heat dissipation fins are disposed between adjacent heat dissipation channels 103, and the coolant in the heat dissipation channel 103 is exchanged for heat through the heat dissipation fins to achieve the heat dissipation effect of the heat dissipation device.

[0026] Located outside the heat dissipation channel 103, the first water chamber 101 and the second water chamber 102 are also connected by an inlet / outlet water assembly 104, a first water channel 105 communicating with the first water chamber 101, and a second water channel 106 communicating with the second water chamber 102. The inlet / outlet water assembly 104 is provided with an inlet 111 communicating with the first water channel 105 and an outlet 112 communicating with the second water channel 106. A partition 107 is also provided inside the first water chamber 101. When liquid enters the first water chamber 101 from the first water channel 105, the liquid flows from the side of the first water chamber 101 near the first water channel 105 to the other side of the first water chamber 101 under the obstruction of the partition 107, and flows in the opposite direction from the other side of the first water chamber 101 to several heat dissipation channels 103.

[0027] In this embodiment, the water inlet / outlet assembly 104 is an integrally formed structure. By setting a first water channel 105, the water inlet / outlet assembly 104, and the second water channel 106 between the first water chamber 101 and the second water chamber 102, the scenario requirement of side water inlet / outlet is met. At the same time, a partition 107 is set in the first water chamber 101. Specifically, the partition 107 is set in the first water chamber 101 and divides the first water chamber 101 into upper and lower layers. A through hole 108 is set on the side of the partition 107 away from the first water channel 105. When liquid enters the first water chamber 101 from the first water channel 105, the liquid flows from the side of the first water chamber 101 near the first water channel 105 to the other side of the first water chamber 101 under the obstruction of the partition 107, and then flows in the opposite direction from the other side of the first water chamber 101 to several heat dissipation channels 103, thereby achieving uniform flow of coolant in the heat dissipation channels 103 and improving the overall heat dissipation efficiency.

[0028] It should be noted that in this embodiment, the inlet 111 and outlet 112 are named according to the flow direction. In the case of another flow direction, the positions of the inlet 111 and outlet 112 are interchanged, and the path of the coolant flow in the heat dissipation device is not affected.

[0029] Furthermore, the heat dissipation channel 103 is arranged side by side with the first water channel 105 and the second water channel 106. The cross-section of the heat dissipation channel 103 is rectangular, and the cross-sectional areas of the first water channel 105 and the second water channel 106 are both larger than the cross-sectional area of ​​the heat dissipation channel 103, thereby ensuring the flow efficiency of the coolant. Preferably, the first water channel 105 and the second water channel 106 are symmetrically arranged with respect to the inlet and outlet water assembly 104.

[0030] Furthermore, the inlet / outlet water assembly 104, the first water channel 105, and the second water channel 106 are externally connected to a cover plate 109, thereby ensuring the overall structural strength of the heat dissipation device.

[0031] Furthermore, a pressure relief valve 110 is provided on the side of the first water chamber 101 near the first water channel 105, which can relieve pressure when the internal air pressure of the heat dissipation device is too high, so as to avoid leakage or explosion.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
