Referring to fig. 2, the heat sink 100 includes a heat dissipation housing 120 and heat dissipation fins 130, wherein the heat dissipation fins 130 are disposed inside the heat dissipation housing 120. The heat dissipation housing 120 may be a rectangular housing, two opposite surfaces of which are an air inlet end and an air outlet end, the heat dissipation housing 120 may also be a cylindrical structure, an upper circular surface and a lower circular surface of which are opposite are an air inlet end and an air outlet end, and the heat dissipation housing 120 may also be in other shapes.

Preferably, the heat dissipation case 120 includes a first side plate 121 and a second side plate 122 which are oppositely disposed, and the first side plate 121 and the second side plate 122 are disposed in parallel. The first end of the heat sink 130 is fixedly connected to the first side plate 121, and the second end of the heat sink 130 is fixedly connected to the second side plate 122.

Preferably, the insulation gap may be parallel to the first side plate 121.

The heat dissipation fins 130 in the fourth heat dissipation area 114 may be disposed perpendicular to the fourth side plate 124, or may be disposed obliquely toward the first side plate 121 or the second side plate 122. One end of the heat sink fin 130 in the fourth heat dissipation area 114, which is away from the fourth side plate 124, has an insulation gap with the heat sink fin 130 in the first heat dissipation area 111 and the second heat dissipation area 112, which is close to the fourth side plate 124, of which, of course, an insulation board may be further disposed in the insulation gap to prevent thermal coupling between the heat generating elements 300 in the first heat dissipation area 111, the second heat dissipation area 112 and the fourth heat dissipation area 114, which affects the heat dissipation efficiency.

Of course, the heat dissipation plate may be provided in plural, and provided on the second side plate 122, the third side plate 123, and the fourth side plate 124, respectively.

Preferably, the heat dissipation plate and the first side plate 121 of the heat dissipation housing 120 are integrally formed, that is, the first side plate 121 directly serves as the heat dissipation plate, and the heating element 300 is mounted on the outer side surface thereof, so that the volume of the heat dissipation system can be reduced, and the heat dissipation efficiency can be improved. The second side plate 122, the third side plate 123 and the fourth side plate 124 may be used as heat dissipation plates to dissipate heat of different heat generating elements 300.

Because of the limited installation space in the photographic equipment, some heating elements may have a certain distance from the heat dissipation system, and in some embodiments, the heat dissipation system further comprises a heat pipe; a space is provided between the heat dissipation plate and the first side plate 121; the first end of the heat pipe is fixedly connected with the first side of the heat dissipation plate, and the second end of the heat pipe is inserted into the second heat dissipation area 112, so that the heat dissipated by the heating element is guided to the heat dissipation plate through the heat pipe for heat dissipation.

The present invention is not particularly limited to this, and those skilled in the art can set the mounting positions of the respective components in the image pickup apparatus. Preferably, the extending direction of the heat conduction pipes in the heat dissipation area intersects with the heat dissipation air channel 131, for example, the heat conduction pipes are perpendicular to the heat dissipation air channel 131, so as to ensure that the air flow in each heat dissipation air channel 131 passes through the heat conduction pipes, and ensure the heat dissipation efficiency.

Referring to fig. 1 to 3, the heat dissipation system of the present embodiment further includes: a heat dissipation support assembly 140; the first side of the heat dissipation support assembly 140 is fixedly connected to the second side plate 122; the heat dissipation support assembly 140 is provided with a slot 141 for mounting a pluggable heating element. The heat dissipation system of the present embodiment is advantageous for heat dissipation while realizing the installation thereof by disposing the pluggable heating element in the slot 141 of the heat dissipation support component 140. The heat dissipation support assembly 140 may be fixedly connected to the second side plate 122 by a fastener such as a screw, and the first side of the heat dissipation support assembly 140 may be integrally formed with the second side plate 122.

For example, the heat dissipation support assembly 140 may be fixedly connected to the third side plate 123, as shown in fig. 2, but the invention is not limited thereto.

The pluggable heating element can be an SSD card, and the SSD card not only needs to meet the allowable working temperature, but also needs to meet the contact temperature during plugging, so the heat dissipation requirement is relatively high. Optionally, the heat dissipation area of the heat dissipation fins 130 in the second heat dissipation region 112 is larger than the heat dissipation area of the heat dissipation fins in the first heat dissipation region 111. Specifically, the length of the heat dissipation fins 130 in the second heat dissipation area 112 along the direction of the heat dissipation air duct 131 is greater than the length of the heat dissipation fins 130 in the first heat dissipation area 111 along the direction of the heat dissipation air duct 131; and/or the distance between the heat insulation gap and the second side plate 122 is greater than the distance between the heat insulation gap and the first side plate 121, so that the heat dissipation efficiency in different heat dissipation areas is different, and heat dissipation of heating elements with different temperatures is realized.

It should be noted that, in the present invention, the heat dissipation areas of the heat dissipation fins 130 in the heat dissipation areas, such as the first heat dissipation area 111, the second heat dissipation area 112, the third heat dissipation area 113, and the fourth heat dissipation area 114, are set according to the heat generating components that actually dissipate heat, wherein the heat dissipation area of the heat dissipation fins 130 in a certain heat dissipation area is relatively large as required by the heat generating components in the certain heat dissipation area.

In other embodiments, a space is formed between the heat dissipation plate and the first side plate 121 of the heat dissipation housing 120, and the heat dissipation plate dissipates heat of the heating element 300 through a heat pipe, at this time, the heat dissipation support assembly 140 of the heat dissipation system may also be located in the space, and the heat dissipation support assembly 140 is fixedly connected with the first side plate 121; the heat dissipation support assembly 140 is provided with a slot 141 for mounting a pluggable heating element. The heat generating elements 300 are all located at one side of the first side plate 121 in the present embodiment. At this time, the second heat dissipation area 112 is formed by, for example: a main control board 310, a power supply board and the like for heat dissipation; the first heat dissipation area 111 couples the pluggable heat-generating component with the heat dissipation support assembly, for example: SSD cards, etc., for heat dissipation. Also, in this case, the heat dissipation area of the heat dissipation fins in the first heat dissipation region 111 is larger than the heat dissipation area of the heat dissipation fins 130 in the second heat dissipation region 112.

It is understood that the heat pipe, the heat dissipation plate, and the heat dissipation support assembly may be disposed on different side plates of the heat dissipation housing 120, and those skilled in the art may set the heat pipe, the heat dissipation plate, and the heat dissipation support assembly according to the specific installation position of the heat generating element in the image capturing apparatus.
