Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power supply packaging structures, in particular to a heat dissipation structure of a power supply component. Background Art
[0002] The power supply component usually has a water cooling plate inside, which absorbs the heat of the heating element and transfers it to the liquid to take away the heat. It can play a good role in cooling protection.
[0003] However, the flow channels of existing water-cooled plates are mostly arranged evenly, which are not closely matched with the specific heating positions of the corresponding heating modules. The flow channel design is unreasonable, and the flow of the flow channel cannot be reasonably distributed, which reduces the heat exchange performance of the water-cooled plate, and further reduces the heat dissipation performance of the power supply components, which also has an adverse impact on safety of use.
[0004] At the same time, the inlet of the flow channel cannot distribute the flow, which reduces the heat exchange efficiency and increases the heat dissipation cost. Utility Model Content
[0005] The utility model aims to provide a heat dissipation structure of a power supply component to solve the problems existing in the background technology.
[0006] The purpose of this utility model is achieved through the following technical solutions:
[0007] A heat dissipation structure of a power supply component, comprising a power supply component, a water-cooling plate and a mounting seat in sequence, wherein the power supply component comprises a first heating area, a second heating area and a third heating area, and the water-cooling plate comprises an inflow end, an outflow end, a first flow channel, a second flow channel and a third flow channel;
[0008] The first flow channel is located at a position corresponding to the first heating zone, the second flow channel is located at a position corresponding to the second heating zone, and the third flow channel is located at a position corresponding to the third heating zone. The area of the first flow channel is larger than the area of the second flow channel, and the area of the second flow channel is larger than the area of the third flow channel. Ribs are provided in the first flow channel, the second flow channel, and the third flow channel.
[0009] The inlet and outlet ends have the same size specifications, the inlet includes a first inlet, a second inlet and a third inlet, the first inlet is connected to the first flow channel, the second inlet is connected to the second flow channel, the third inlet is connected to the third flow channel, the first inlet is larger than the second inlet, and the second inlet is larger than the third inlet.
[0010] Furthermore, the number of ribs in the first flow channel, the second flow channel and the third flow channel decreases successively.
[0011] Furthermore, the middlemost rib plate in the first flow channel is a U-shaped structure, and the middlemost rib plate in the first flow channel divides the first inlet into two parts.
[0012] Furthermore, the rib plate in the third flow channel is provided with a protrusion, and the shape of the protrusion is adapted to the shape of the third flow channel.
[0013] The beneficial effects of the utility model are:
[0014] 1) Each flow channel is adapted to the shape of the corresponding heating area to increase the heat dissipation area and heat dissipation effect. Setting different flow channels according to the heat generation of different areas can effectively and reasonably dissipate heat and improve the heat exchange effect of the water cooling plate.
[0015] 2) The vertical arrangement of the ribs has a heat conduction effect. The heat is conducted through multiple ribs and then dissipated through the flow channels on both sides of the ribs, thereby improving the heat dissipation effect. At the same time, the flow in each flow channel is separated by the ribs to ensure uniform flow and improve the heat exchange effect.
[0016] 3) Setting inlets of different sizes according to heat dissipation requirements can help to reasonably distribute flow and reduce waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:
[0024] like Figure 1-Figure 4 As shown, a heat dissipation structure of a power supply component, a water cooling plate 1 and a power supply component 5 are fixed on a mounting base in sequence, and the water cooling plate 1 is in contact with the heating surface of the power supply component 5. The power supply component 5 in this embodiment includes a first heating area, a second heating area and a third heating area, the first flow channel 21 of the water cooling plate 1 is located below the corresponding first heating area, the second flow channel 22 is located below the corresponding second heating area, and the third flow channel 23 is located below the corresponding third heating area.
[0025] It can be known that the heat generation of the first heating zone is greater than that of the second heating zone, and the heat generation of the second heating zone is greater than that of the third heating zone, so the area of the first flow channel 21 is greater than that of the second flow channel 22, and the area of the second flow channel 22 is greater than that of the third flow channel 23. At the same time, each flow channel is adapted to the shape of the corresponding heating zone to increase the heat dissipation area and heat dissipation effect. Setting different flow channels according to the heat generation of different areas can efficiently and reasonably dissipate heat and improve the heat exchange effect of the water-cooled plate 1.
[0026] At the same time, rib plates 24 are provided in the first flow channel 21, the second flow channel 22 and the third flow channel 23. The rib plates 24 are used to separate the flow channels so that the liquid can be evenly distributed in the flow channels. At the same time, the vertical arrangement of the rib plates 24 can also play a heat conduction effect. The heat is conducted through multiple rib plates 24, and then dissipated through the flow channels on both sides of the rib plates 24, thereby improving the heat dissipation effect.
[0027] In this embodiment, the inflow end 3 and the outflow end 4 are located on the same side, and the inflow end 3 and the outflow end 4 have the same structure. The inflow end 3 includes a first inlet 31, a second inlet 32 and a third inlet 33. The first inlet 31 is connected to the first flow channel 21, the second inlet 32 is connected to the second flow channel 22, and the third inlet 33 is connected to the third flow channel 23. Since the first flow channel 21 requires a large flow rate, the second flow channel 22 requires the second flow rate, and the third flow channel 23 requires the least flow rate. Therefore, the corresponding sizes of the first inlet 31, the second inlet 32 and the third inlet 33 are reduced in sequence. Setting inlets of different sizes according to heat dissipation requirements can play a role in reasonably allocating flow and reducing waste.
[0028] Furthermore, the number of ribs 24 in the first flow channel 21 , the second flow channel 22 and the third flow channel 23 decreases successively.
[0029] Through the above technical solution, five evenly arranged ribs 24 are provided in the first flow channel 21, two evenly arranged ribs 24 are provided in the second flow channel 22, and one rib 24 is provided in the third flow channel 23. The flow in each flow channel is separated by the ribs 24 to ensure uniform flow and improve heat exchange effect.
[0030] Furthermore, the middlemost rib plate 24 in the first flow channel 21 is a U-shaped structure, and the middlemost rib plate 24 in the first flow channel 21 divides the first inlet 31 into two parts.
[0031] Through the above technical solution, the first inlet 31 is divided into two parts by the U-shaped rib plate 24, and the flow entering the first flow channel 21 is divided into two directions through the inlet and then subdivided by the rib plate 24, thereby ensuring that the flow in the first flow channel 21 is uniform and improving the heat exchange effect.
[0032] Furthermore, the rib plate 24 in the third flow channel 23 is provided with a protrusion 25 , and the shape of the protrusion 25 is adapted to the shape of the third flow channel 23 .
[0033] Through the above technical solution, according to the heating area of the power supply component 5, the flow path of the third flow channel 23 can be adjusted by setting the protrusion 25 to better fit the heating area and improve the heat exchange effect.
[0034] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be protected by the claims attached to the utility model.
