[0028] The utility model provides a heat dissipation device and an electronic device. Figures 1 to 5 A specific embodiment of a heat dissipation device and an electronic device provided by the utility model.
[0029] like Figure 1 and Figure 3 As shown, an embodiment of the utility model provides a heat dissipation device 100, including a main body 1 and a connecting portion 2 for connecting a wire, the main body 1 having a first side and a second side opposite to each other, the first side of the main body 1 is provided with a mounting hole for mounting a circuit board 300, and the first side is formed with a heat dissipation area for heat dissipation of the heat-generating components of the circuit board 300, the connecting portion 2 is provided at one end of the main body 1 to electrically connect the main body 1 to the wire.
[0030] It should be noted that the main body 1 and the connecting part 2 are made of conductive materials, but the heat dissipation area is not conductive, so as to prevent the current on the main body 1 from affecting the normal operation of the components on the circuit board 300 .
[0031] In the present invention, the main body 1 has a first side and a second side opposite to each other. The circuit board 300 is installed on the first side of the main body 1 through the installation hole. The first side forms a heat dissipation area at the position of the heat-generating component corresponding to the circuit board 300. The heat of the heat-generating component is conducted out through the heat dissipation area. At the same time, the connecting part 2 is connected to the wire, so that the main body 1 is electrically connected to the wire. Both the connecting part 2 and the main body 1 can conduct electricity. When the second side of the main body 1 is connected to an electrical device, the current of the wire can be transmitted to the electrical device. The heat dissipation device 100 takes into account the functions of heat dissipation and conduction. Compared with the existing heat dissipation devices, the use of wires is reduced, thereby reducing the assembly cost.
[0032] Since the main body 1 is conductive, the circuit board 300 needs to maintain a certain distance from the main body 1 to prevent the current in the main body 1 from affecting the normal operation of the components on the circuit board 300. Therefore, a gap needs to be left between the heat-generating components on the circuit board 300 and the heat-dissipating area on the main body 1. However, the thermal conductivity of air is poor, which will affect the heat dissipation of the heat-generating components. Therefore, in some embodiments, Figure 5 As shown, the main body 1 is provided with a heat dissipation portion 11 protruding from the heat dissipation area for the heat dissipation of the heat generating component. In this way, since the heat dissipation portion 11 is protruding and abuts against the heat generating component, the heat of the heat generating component can be conducted to the main body 1 through the heat dissipation portion 11.
[0033] Furthermore, there is still a gap between the heat dissipation portion 11 and the heat generating component, and the heat dissipation portion 11 is integrally formed with the main body 1. The thermal conductivity of the heat dissipation portion 11 is limited by the main body 1 and may not meet the heat dissipation requirements. Therefore, in some embodiments, Figure 5 As shown, the heat dissipation portion 11 is covered with a heat conducting portion 12 so that the heat of the heat generating component is transferred to the heat dissipation portion 11. Since the heat conducting portion 12 is arranged between the heat dissipation portion 11 and the heat generating component, the heat conducting portion 12 is made of fluid or elastic material, and can fill the gap between the heat dissipation portion 11 and the heat generating component, and the heat conducting portion 12 has a good thermal conductivity, which can meet the heat dissipation requirements of the heat generating component.
[0034] Specifically, the heat conducting portion 12 includes thermal conductive silicone grease or other materials known to those skilled in the art that have good thermal conductivity but are not electrically conductive.
[0035] It should be noted that the present invention also includes a technical solution in which the heat dissipation portion 11 is removed and the space between the heat dissipation area and the heat-generating component is only filled with the heat conduction portion 12 .
[0036] Since the main body 1 and the connecting part 2 have a conductive function, when the second side of the main body 1 is connected to an electrical device, the current in the wire can be delivered to the electrical device. In some embodiments, such as Figure 1As shown, a connector 3 is provided on the second side of the main body 1 at the position corresponding to the heat dissipation area, and the heat dissipation device 100 also includes a heat dissipation component 4 having one end for connecting to the heating core, and the other end of the heat dissipation component 4 is connected to the connector 3, so that the heating core is electrically connected to the wire. The heating core is an electrical device. With such a configuration, on the one hand, the connector 3 and the heat dissipation component 4 can act as wires, avoiding the need for additional wire laying, and reducing production and assembly costs. On the other hand, the connector 3 is provided at the heat dissipation area, which can extract the heat from the heat dissipation area, avoiding serious heat accumulation, temperature rise, and reduced heat dissipation capacity in the heat dissipation area after long-term use.
[0037] Furthermore, in some embodiments, Figure 1 As shown, the main body 1 is provided with two connecting members 3 at intervals in the length direction thereof, and the heat dissipation assembly 4 includes two heat dissipation bars 41, each of which is connected to the connecting member 3 in a one-to-one correspondence, and the two heat dissipation bars 41 extend along the length direction of the heating core to dissipate heat from the heating core. In this arrangement, the two heat dissipation bars 41 can not only dissipate heat from the heating core, but also extract the heat transferred from the heat dissipation area to the connecting member 3.
[0038] Specifically, the two heat dissipation strips 41 are respectively connected to the positive and negative poles of the heating core. After the current flows in from the wire, it flows through the connecting part 2, the main body 1, the connecting piece 3 and the heat dissipation strip 41, flows in from the positive pole of the heating core, flows out from the negative pole, and then flows through the other heat dissipation strip 41 and the connecting piece 3 to the main body 1, and finally flows out from the wire connected to the other connecting part 2, forming a current loop.
[0039] Since the main body 1 and the heat dissipation strip 41 connected by the connecting member 3 need to dissipate heat for the heating component and the heating core respectively, heat is accumulated near the connecting member 3. In order to avoid the temperature of the connecting member 3 being too high and affecting the service life for a long time, in some embodiments, as Figure 2 As shown, the connector 3 is connected with a heat sink 5, and the heat sink 5 extends along the length direction of the main body 1. In this way, the heat of the connector 3 is conducted out through the heat sink 5, the temperature of the connector 3 is reduced, and the service life of the connector 3 is increased.
[0040] Specifically, the heat sink 5 is disposed between the two connectors 3 and is connected to the two connectors 3 at the same time, which can, on the one hand, dissipate the heat of the two connectors 3 and, on the other hand, improve the connection stability of the connectors 3 .
[0041] Furthermore, the specific shape of the heat sink 5 is not limited, as long as the heat sink 5 can extract the heat of the connector 3. For example, in some embodiments, Figure 2 As shown, a plurality of heat dissipation blocks 6 are protruded from the side of the heat dissipation member 5 facing away from the connecting member 3, and the plurality of heat dissipation blocks 6 are arranged at intervals in the length direction of the heat dissipation member 5. Such arrangement increases the contact area between the heat dissipation member 5 and the air, and improves the heat dissipation effect of the heat dissipation member 5.
[0042] In addition, if Figure 4 As shown, the utility model also provides an electronic device 1000, including a shell 200, a circuit board 300, a heating core and any one of the above-mentioned heat dissipation devices 100, the heat dissipation device 100 including a main body 1 and a connecting portion 2 for connecting a wire, the main body 1 having a first side and a second side opposite to each other, the first side of the main body 1 is provided with a mounting hole for mounting the circuit board 300, and the first side is formed with a heat dissipation area for heat dissipation of the heating components of the circuit board 300, the connecting portion 2 is provided at one end of the main body 1 to electrically connect the main body 1 with the wire, the circuit board 300, the heating core and the heat dissipation device 100 are all provided in the shell 200, and the circuit board 300 and the heating core are respectively installed on the first side and the second side of the main body 1 in the heat dissipation device 100.
[0043] Since all components of the electronic device 1000 are arranged in the housing 200, the temperature in the housing 200 rises after long-term use, resulting in a decrease in the heat dissipation effect of the heat dissipation device 100. Therefore, in some embodiments, an air inlet and an air outlet are provided on the housing 200, and the air inlet and the air outlet are provided corresponding to the second side of the main body 1 so that air can take away the heat of the main body 1. Since the main body 1 and the heat dissipation strip 41 dissipate heat to the heat-generating components and the heat-generating core respectively, the heat is accumulated near the connecting member 3, that is, near the second side of the main body 1. The air inlet and the air outlet are provided corresponding to the second side of the main body 1, so that the second side of the main body 1 is located in the air duct, and the heat accumulated on the second side of the main body 1 can be taken away by the cold air from the outside.
[0044] In some embodiments, the circuit board 300 is provided with a fixing hole at a position corresponding to the mounting hole of the main body 1, and a threaded connection structure is provided through the mounting hole and the fixing hole, and the circuit board 300 and the heat sink 100 are fixed to the housing 200 through the threaded connection structure. Such a setting is more stable than fixing methods such as buckles, and is also easy to disassemble when parts are damaged and need to be replaced.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
