Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical equipment, in particular to a radiator and electrical equipment. Background Art
[0002] Air cooling is often used for heat dissipation of radiators. The core idea of heat dissipation is to use a fan to exchange heat between the radiator and the outside air, where the outside air is the low-temperature side. After heat exchange, the heat is transferred from the inside of the radiator to the outside environment.
[0003] At present, the conventional heat sink includes multiple electrical components (heat sources), a substrate and a heat dissipation fin group. The electrical components and the heat dissipation fin group are respectively mounted on a pair of oppositely disposed end surfaces of the substrate. After the heat dissipation fin group is mounted on the substrate in a manner perpendicular to or parallel to the edge of the substrate, the heat dissipation area where any electrical component is located is evenly divided by multiple heat dissipation channels, that is, the heat dissipation area where any electrical component is located is equally divided by multiple heat dissipation channels, resulting in the same degree of temperature rise generated by the air branches in each heat dissipation channel after the outside air flows through any electrical component in each heat dissipation channel under the action of the fan, resulting in poor heat dissipation effect.

[0010] Beneficial effect: Through the setting of the air guide plate group, the air at the fan group and flowing to one side or both sides thereof can be guided, thereby increasing the utilization of the air and allowing the outer edge heat dissipation teeth at the outer edge of the heat dissipation tooth group to also undergo sufficient heat exchange, that is, making full use of each heat dissipation tooth, thereby enhancing the heat dissipation effect.

[0033] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment 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.
[0034] A traditional radiator includes a plurality of electrical components (heat sources), a substrate, and a heat dissipation fin group. The electrical components and the heat dissipation fin group are respectively installed on a pair of oppositely arranged end surfaces of the substrate. After the heat dissipation fin group is installed on the substrate in a manner perpendicular to or parallel to the edge of the substrate, the heat dissipation area where any electrical component is located is evenly divided by a plurality of heat dissipation channels, that is, the heat dissipation area where any electrical component is located is equally divided by a plurality of heat dissipation channels, resulting in that when the outside air flows in each heat dissipation channel under the action of a fan, after flowing through any electrical component, the temperature rise degree generated in each heat dissipation channel is the same, resulting in poor heat dissipation effect. To this end, the utility model arranges the heat dissipation channels obliquely, not only adding a heat dissipation channel for heat exchange of the electrical components, but also generating a temperature gradient between adjacent heat dissipation channels, so that adjacent heat dissipation channels participate in heat exchange, thereby achieving improved heat dissipation effect.
[0035] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.
[0036] In a first aspect, this embodiment provides a heat sink. Specifically, Figure 1 and Figure 2 As shown, the heat sink includes a substrate 1, an electrical component 2 and a heat sink fin group 3. The substrate 1 is provided with a pair of mounting surfaces 101 arranged opposite to each other; a plurality of electrical components 2 are provided, and the plurality of electrical components 2 are mounted on one of the mounting surfaces 101; the heat sink fin group 3 includes a plurality of heat sink fins 301, and the plurality of heat sink fins 301 are evenly arranged in the other mounting surface 101 at a fixed interval to form a plurality of parallel heat sink channels. During installation, any heat sink fin 301 is installed perpendicular to the substrate 1, and the extension direction of any heat sink channel is arranged to intersect with the outer edge of the substrate 1, so that any heat sink channel is arranged obliquely on the substrate 1.
[0037] By using the technical solution of this embodiment, the number of heat dissipation channels corresponding to each electrical component 2 can be increased, and the heat dissipation areas set for the same electrical component 2 in adjacent heat dissipation channels can be different, so that the temperature rise degree of the air in each heat dissipation channel is different when passing through the electrical component 2, thereby making the temperature gradient of each heat dissipation channel different, so that heat exchange is performed between adjacent heat dissipation channels, and then the electrical component 2 is fully exchanged, thereby enhancing the heat dissipation effect of the radiator. Therefore, the problem of poor heat dissipation effect caused by the same temperature rise degree in each heat dissipation channel in the prior art radiator is solved.
[0038] like Figure 1 As shown, the heat sink further includes a fan group 5 , which is arranged on the same mounting surface 101 of the base plate 1 as the heat dissipation fin group 3 , and the heat dissipation fin group 3 is arranged in pairs and respectively arranged on two opposite sides of the fan group 5 .
[0039] By utilizing the technical solution of this embodiment, air is made to flow in opposite directions toward the two groups of heat dissipation channels formed by the two groups of heat dissipation fin groups 3, shortening the heat dissipation path of each heat dissipation channel and reducing the temperature difference between the inlet and outlet ends of the heat dissipation channel, so that the heat dissipation degree of each heat source is more uniform, thereby further enhancing the heat dissipation effect of the radiator.
[0040] It can be explained that the number of fans in the fan group 5 is not specifically limited and can be flexibly selected according to the sizes of the radiator, such as one, two, three or more.
[0041] As one of the implementation methods, Figure 1 , Figure 2 and Figure 5 As shown, three fans are provided in the radiator. Of course, in other optional embodiments, such as Figure 3 As shown, there are two fans inside the radiator.
[0042] Since the fan tends to dissipate cold air to both sides when it is working, it is necessary to Figure 3 The fan group 5 shown in the figure is provided with an air guide structure on both sides of the horizontal direction. Figure 1 and Figure 3 As shown, the radiator further includes an air guide plate group 4. The air guide plate group 4 encloses an air guide chamber 401, the air inlet end of the air guide chamber 401 is connected to at least one cold air dissipation outlet of the fan group, and the air guide end of the air guide chamber 401 is connected to at least one heat dissipation channel inlet.
[0043] By utilizing the technical solution of this embodiment, the cold air escaping from the fan group is guided into at least one heat dissipation channel inlet, thereby realizing the reuse of the cold air, improving the heat exchange degree of the air in the heat dissipation channel, and further enhancing the heat dissipation effect of the radiator.
[0044] It can be explained that the structure of the air guide plate group 4 is not specifically limited.
[0045] As one of the embodiments, the air guide plate group 4 includes at least a first plate body 402 and a second plate body 403, both of which are perpendicular to the mounting surface 101, one end of the first plate body 402 is connected to an outer edge heat dissipation fin 301 of a heat dissipation fin group 3, and the other end of the first plate body 402 extends in a direction away from the mounting surface 101, one end of the second plate body 403 is connected to the other end of the first plate body 402, and the other end of the second plate body 403 extends in the direction of an outer edge heat dissipation fin 301 of another heat dissipation fin group 3 to enclose an air guide chamber 401.
[0046] By using the technical solution of this embodiment, the air at the fan group 5 and flowing to both sides thereof can be guided to increase the utilization of the air. Figure 1 and Figure 3 As shown, the cold air is first directed to the outer edge heat dissipation fins of the heat dissipation fin group 3, and sufficient heat exchange is performed on the outer edge heat dissipation fins, that is, each heat dissipation fin 301 is fully utilized to enhance the heat dissipation effect.
[0047] Likewise, there is no specific limitation on the wind guide direction.
[0048] Specifically in this embodiment, Figure 3 As shown, the included angle between the second plate body 403 and any heat dissipation channel is A, and the value of A satisfies 90°≥A≥45°, so as to facilitate the introduction of the escaped air back into the heat dissipation channel.
[0049] Preferably, A=90°.
[0050] Furthermore, if Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the air guide plate group 4 also includes a third plate body 404, which is perpendicular to the mounting surface 101, one end of the third plate body 404 is connected to the other end of the second plate body 403, and the other end of the third plate body 404 is connected to the outer edge heat dissipation fin 301 of another heat dissipation fin group 3.
[0051] In addition, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the air guide plate group 4 also includes a fourth plate body 405, which is parallel to the mounting surface 101, preferably coplanarly arranged, and the fourth plate body 405 is connected to the first plate body 402, the second plate body 403 and the third plate body 404, and the first plate body 402, the second plate body 403, the third plate body 404 and the fourth plate body 405 enclose an air guide chamber 401, and the air guiding direction of the air guide chamber 401 is toward the heat dissipation channel of another heat dissipation fin group 3.
[0052] By utilizing the technical solution of this embodiment, the degree of air guidance is improved and the heat dissipation effect is further enhanced.
[0053] It can be explained that there is no specific limitation on the molding method of the first plate body 402 , the second plate body 403 , the third plate body 404 and the fourth plate body 405 .
[0054] As one implementation manner, the first plate body 402, the second plate body 403, the third plate body 404 and the fourth plate body 405 are split structures and are welded and fixed in sequence during installation.
[0055] Of course, in other optional implementations, the first plate body 402, the second plate body 403, the third plate body 404 and the fourth plate body 405 are integrally formed. For example, a plate blank is selected and presents a multi-section bending structure after stamping.
[0056] In addition, aluminum can also be selected and extruded.
[0057] It can be explained that, in order to further improve the heat dissipation effect of the radiator, the air guide plate groups 4 are arranged in pairs and symmetrically distributed on both sides of the fan group 5, such as one pair, two pairs or more pairs.
[0058] As one embodiment, a pair of air guide plate groups 4 are provided.
[0059] By utilizing the technical solution of this embodiment, the heat dissipation fins 301 in each heat dissipation fin group 3 are all involved in heat exchange, thereby further enhancing the heat dissipation effect and the uniformity of heat dissipation.
[0060] It can be explained that there is no specific limitation on the structure of the substrate 1. It can be a square plate or a circular plate.
[0061] As one embodiment, the substrate 1 is a square plate. Figures 1 to 6 As shown, the base plate 1 at least includes a horizontal outer edge 103; the angle between the extension direction of any heat dissipation fin 301 and the extension direction of the horizontal outer edge 103 is B, 60°≥B≥30°. Preferably, B=45°.
[0062] Furthermore, the base plate 1 is a square plate, so the base plate 1 further includes a vertical outer edge 104. At this time, the vertical outer edge 104 and the horizontal outer edge 103 are arranged perpendicularly in the plane.
[0063] That is, the extension direction of any heat dissipation channel is arranged crosswise with the extension direction of any edge of the substrate 1, so that the heat dissipation fins 301 are arranged obliquely, and the area of the heat dissipation area generated by any heat dissipation channel on the electrical component 2 projected onto the mounting surface 101 is different from the area of the heat dissipation area covered by the adjacent heat dissipation channel on the electrical component 2. Figure 4 As shown, the heat dissipation area of a heat dissipation channel covering an electrical component is S1, and the heat dissipation area of an adjacent heat dissipation channel covering an electrical component is S2, S1<S2, and the temperature rise after passing through S1 is less than the temperature rise after passing through S2, so that a temperature gradient is generated between the two adjacent heat dissipation channels, thereby allowing heat exchange between the two heat dissipation channels.
[0064] It can be explained that there is no specific limitation on the composition of the substrate 1. It can be composed of a single piece, or can be composed of two, three or more pieces spliced together.
[0065] As one of the implementation methods, Figure 1and Figure 3 As shown, the base plate 1 includes two fifth plate bodies 102 , and the two fifth plate bodies 102 are welded and fixed.
[0066] In a second aspect, the utility model further provides an electrical device, comprising the radiator in the first aspect.
