Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment technology, and in particular to a heat sink. Background Technology

[0002] Existing radiators include liquid cooling plates, which have channels for the flow of heat exchange medium. The liquid cooling plates have inlets and outlets that communicate with the channels. The heat exchange medium flows in from the inlet, flows through the entire channel, and flows out from the outlet. Heat exchange is completed during the flow process in the channel to cool down the components to be cooled. However, the heat exchange efficiency of this type of liquid cooling plate is not high, and it is also prone to uneven heat exchange. Utility Model Content

[0003] In view of the above-mentioned technical problems, this utility model provides a heat sink.

[0028] Please see Figures 1-5 The present invention provides a radiator 100, including a heat sink 101. The heat sink 101 has multiple first flow channels 10 and second flow channels 20 arranged alternately along the thickness direction to make the heat exchange more uniform and the heat exchange efficiency higher.

[0029] The heat sink 101 has a first flow channel 10 and a second flow channel 20 for the flow of medium. The heat sink 101 has a first direction and a second direction that are set at an angle. The first flow channel 10 extends along the first direction and the second flow channel 20 extends along the second direction. The heat sink 101 has a thickness direction that is perpendicular to both the first direction and the second direction. The first flow channel 10 and the second flow channel 20 are spaced apart in the thickness direction and are not directly connected.

[0030] In this way, the first flow channel 10 and the second flow channel 20 can evenly distribute the heat exchange medium, and the first direction and the second direction are staggered in the thickness direction, which can effectively avoid local temperature being too high or too low, thereby achieving a more uniform temperature distribution and improving the stability and efficiency of heat exchange.

[0031] It should be explained that, in this embodiment, the first flow channel 10 and the second flow channel 20 being spaced apart in the thickness direction means that the first flow channel 10 and the second flow channel 20 are not on the same plane. The first direction refers to the length direction of the heat sink 101, and the second direction refers to the width direction of the heat sink 101. The two are perpendicular to each other, that is, the first flow channel 10 and the second flow channel 20 are on the thickness direction of the heat sink 101.

[0032] Furthermore, multiple first flow channels 10 are configured, each extending along a first direction and evenly spaced along a second direction. The multiple first flow channels 10 improve the uniformity of heat exchange medium distribution and also make the temperature on the heat sink 101 more uniform.

[0033] Furthermore, multiple first flow channels 10 are spaced apart along the thickness direction of the heat sink 101 to form multiple layers of first flow channels 10. At least some of the first flow channels 10 are staggered along the thickness direction of the heat sink 101, meaning that the projections of each layer of first flow channels 10 do not overlap along the thickness direction of the heat sink 101. In this way, the first flow channels 10 themselves form a multi-layer heat dissipation structure along the thickness direction, thereby improving heat dissipation uniformity and efficiency.

[0034] In other embodiments, the multiple first channels 10 can also be arranged one-to-one in the thickness direction of the heat sink 101, that is, the projections of the multiple first channels 10 in the thickness direction of the heat sink 101 overlap, which can also achieve the effect of uniform heat dissipation, and is not limited to the staggered arrangement described above.

[0035] Similarly, multiple second flow channels 20 are configured, each extending along a second direction and evenly spaced along a first direction. In this way, multiple second flow channels 20 can improve the uniformity of heat exchange medium distribution and make the temperature on the heat sink 101 more uniform.

[0036] Multiple second flow channels 20 are configured, and these multiple second flow channels 20 are spaced apart in the thickness direction of the heat sink 101 to form a multi-layer second flow channel 20. At least some of the second flow channels 20 do not overlap in the thickness direction of the heat sink 101, and the first flow channel 10 and the second flow channel 20 are staggered in the thickness direction. In this way, the second flow channels 20 themselves form a multi-layer heat dissipation structure in the thickness direction to improve heat dissipation uniformity and efficiency.

[0037] Preferably, in this embodiment, the heat sink 101 is rectangular, and multiple first flow channels 10 are evenly spaced along the length and thickness directions of the heat sink 101. Multiple second flow channels 20 are also evenly spaced along the width and thickness directions of the heat sink 101, and the first flow channels 10 and the second flow channels 20 are perpendicular to each other in the thickness direction.

[0038] The heat sink 101 is connected to at least one inlet pipe 30 and at least one outlet pipe 40. Both ends of the first flow channel 10 and the second flow channel 20 are connected to the inlet pipe 30 and the outlet pipe 40, respectively. In this way, the heat exchange medium flows into the multiple first flow channels 10 and multiple second flow channels 20 through the inlet pipe 30, and then flows out from the other end of the first flow channel 10 and the second flow channel 20, and flows out through the outlet pipe 40.

[0039] To facilitate the collection of heat exchange media at the ends of the first flow channel 10 and the second flow channel 20, this utility model also provides a flow collection cavity.

[0040] Please see Figures 1-3 In Embodiment 1, the heat sink 101 is constructed with a first collecting cavity 50, a second collecting cavity 60, a third collecting cavity 70, and a fourth collecting cavity 80. The two ends of the first flow channel 10 are connected to the first collecting cavity 50 and the second collecting cavity 60, respectively. The two ends of the second flow channel 20 are connected to the third collecting cavity 70 and the fourth collecting cavity 80, respectively. One of the first collecting cavities 50 and 60 is connected to at least one inlet pipe 30, and the other is connected to at least one outlet pipe 40. Similarly, one of the third collecting cavities 70 and 80 is connected to at least one inlet pipe 30, and the other is connected to at least one outlet pipe 40. Thus, the four collecting cavities independently control the entry and exit of the heat exchange medium, resulting in better structural stability. Furthermore, the heat exchange medium in the first flow channel 10 or the second flow channel 20 can be adjusted according to actual conditions, flexibly adjusting the heat dissipation efficiency of the radiator. For example, the heat exchange medium flows into the first manifold 50 from the inlet pipe 30. Multiple and multi-layered first flow channels 10 are connected to the first manifold 50. The heat exchange medium simultaneously enters multiple first flow channels 10, then enters the second manifold 60 from the other end of the first flow channel 10, and then flows out from the outlet pipe 40. Similarly, on the other side, the heat exchange medium flows into the third manifold 70 from the inlet pipe 30. Multiple and multi-layered second flow channels 20 are connected to the third manifold 70. The heat exchange medium simultaneously enters multiple second flow channels 20, then enters the fourth manifold 80 from the other end of the second flow channel 20, and then flows out from the outlet pipe 40.

[0041] It should be explained that the first collection cavity 50, the second collection cavity 60, the third collection cavity 70 and the fourth collection cavity 80 are not directly connected. However, not being directly connected does not mean that they cannot be connected. In other embodiments, the above collection cavities can be connected through other pipelines.

[0042] Please see Figures 4-5In Embodiment Two, the radiator 100 is constructed with a first collecting cavity 50 and a second collecting cavity 60. One end of the first flow channel 10 and one end of the second flow channel 20 are both connected to the first collecting cavity 50, and the other end of the first flow channel 10 and the other end of the second flow channel 20 are both connected to the second collecting cavity 60. One of the first collecting cavity 50 and the second collecting cavity 60 is connected to at least one inlet pipe 30, and the other is connected to at least one outlet pipe 40. Thus, compared with Embodiment One, Embodiment Two has a simpler structure, is easier to manufacture, and still allows the heat exchange medium to flow in and out smoothly.

[0043] Furthermore, the heat sink 101 is rectangular, the first collection cavity 50 is located on the adjacent two sides of the heat sink 101, and the second collection cavity 60 is located on the other adjacent two sides of the heat sink 101.

[0044] Furthermore, the first flow channel 10 includes multiple first sub-flow channels, which are spaced apart along a second direction; and / or, the second flow channel 20 includes multiple second sub-flow channels 15, which are spaced apart along a first direction, to improve the uniformity of heat exchange medium distribution. Specifically, the first sub-flow channels in the first flow channel 10 and the second sub-flow channels 15 in the second flow channel 20 form a first path 11, a second path 12, and a third path 13, which are spaced apart along the thickness direction of the heat dissipation plate 101. This further improves the uniformity of heat exchange medium distribution. The first flow channel 10 and the second flow channel 20, by dividing into three paths, are configured as microchannel flow channel structures with smaller hydraulic diameters and thinner boundary layers. The flow state of the fluid in the pipe is closer to laminar flow, resulting in faster and more efficient heat transfer, and the heat transfer coefficient is significantly improved compared to traditional flow channel structures.

[0045] In this embodiment, a fourth channel 14 can be added to make the heat exchange medium distribution more balanced.

[0046] Furthermore, the first flow channel 10 and the second flow channel 20 are provided with protruding internal teeth, which increase the contact area between the inner wall of the first flow channel 10 and the second flow channel 20 and the heat exchange medium, thereby improving the heat exchange efficiency.

[0047] Compared to existing technologies, this invention effectively avoids localized excessively high or low temperatures by using staggered first flow channels 10 and second flow channels 20, thereby achieving a more uniform temperature distribution and improving the stability and efficiency of heat exchange. Furthermore, the layout and structure of the first flow channels 10 and second flow channels 20 are optimized to further enhance the heat exchange capacity of the radiator 100.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
