[0002] In existing cameras, in order to achieve heat dissipation, heat is generally dissipated by conducting heat through a single heat dissipation aluminum block, or a heat dissipation aluminum block and a small air volume fan (4010 or less) are set to exhaust air for heat dissipation. However, this method has many problems:

[0004] 2. Low heat dissipation efficiency, high temperature or above 50 degrees, directly affects the life of the camera and shooting, etc.;

[0005] 3. It is difficult for users to clean and replace the fan.

[0006] 4. The heat dissipation aluminum block may be too large, so the camera will inevitably be bulky and heavy. Utility Model Content

[0009] In one embodiment, the heat source plate and the contact heat dissipation plate are both in multiple pieces; the multiple contact heat dissipation plates are arranged separately, and the heat source plate is provided between adjacent contact heat dissipation plates.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] The utility model provides a novel heat dissipation camera, which can be implemented as follows: Figure 1 and Figure 2 As shown, the housing 10 includes a heat source plate 20 , a contact heat dissipation plate 30 , a liquid-cooled heat dissipation plate 40 and a fan 50 arranged in the housing 10 .

[0033] Regarding the housing 10, Figure 1 and Figure 2 As shown, the housing 10 of this embodiment is a rectangular frame structure, which is hollow inside so as to have a larger space to accommodate the heat source plate 20, the contact heat dissipation plate 30, the liquid cooling heat dissipation plate 40, the fan 50, and other related components.

[0034] Among them, the two opposite side covers 11 of the casing 10 are both provided with ventilation holes 12, so that the internal heat can be discharged to the outside of the casing 10 through the ventilation holes 12 in time; and this embodiment also arranges a detachable screw connection between the side cover 11 and the casing 10, and the side cover 11 can be threadedly connected with the threaded holes on the casing 10 by only using screws to pass through the through holes at its four end corners. This connection method is simple and convenient, so that the user can disassemble and clean the camera easily.

[0035] Regarding the heat source block 20, Figures 2 to 5 As shown, the heat source plate 20 is actually a device or circuit board that generates heat. For example, the heat source plate 20 in this embodiment is a PCA circuit board. The heat generated by it needs to be sent to the outside of the housing 10 in time. Therefore, in this embodiment, the heat source plate 20 is arranged between the contact heat dissipation plate 30 and the liquid-cooled heat dissipation plate 40, and the two opposite surfaces of the heat source plate 20 are kept in contact with the contact heat dissipation plate 30 and the liquid-cooled heat dissipation plate 40 respectively, so as to ensure that the heat generated by the heat source plate 20 can be transferred to the contact heat dissipation plate 30 and the liquid-cooled heat dissipation plate 40 in time.

[0036] Among them, since there are usually multiple devices and circuit boards that can generate heat in the camera, that is, there will be multiple heat source areas inside the camera, in order to ensure that the heat is fully and efficiently discharged, it should be ensured that the heat generated by each heat source area can be delivered to the contact heat dissipation plate 30 and the liquid-cooled heat dissipation plate 40 in time.

[0037] For example, the heat source plate 20 and the contact heat dissipation plate 30 provided in this embodiment are both multiple, and the multiple contact heat dissipation plates 30 are arranged separately, and heat source plates 20 are provided between adjacent contact heat dissipation plates 30, so that it is ensured that both sides of the heat source plate 20 can efficiently transfer heat to the contact heat dissipation plate 30, thereby realizing all-round heat dissipation inside the camera.

[0038] This embodiment also provides a heat source plate 20 between the liquid-cooled heat dissipation plate 40 and the rear cover 13 of the casing 10. The heat source plate 20 abuts against the liquid-cooled heat dissipation plate 40, thereby ensuring that the two opposite surfaces of the liquid-cooled heat dissipation plate 40 can receive the heat emitted by the heat source plate 20, thereby further improving the utilization efficiency of the liquid-cooled heat dissipation plate 40.

[0039] In addition, since the contact heat dissipation plate 30 and the liquid-cooled heat dissipation plate 40 also cooperate with the fan 50 to achieve air-cooled heat dissipation, in order to ensure that the heat can be promptly sent to the outside of the casing 10 by air cooling, this embodiment is provided with a ventilation channel 60 on the contact heat dissipation plate 30 and the liquid-cooled heat dissipation plate 40. The ventilation channel 60 is connected to the ventilation holes 12 on both sides of the casing 10, so the fan 50 can send air through the ventilation channel 60, and the heat generated in the casing 10 is discharged through the ventilation holes 12 in time.

[0040] In order to ensure smooth heat transfer, this embodiment provides multiple ventilation channels 60 on the contact heat dissipation plate 30 and the liquid cooling heat dissipation plate 40. The multiple ventilation channels 60 are arranged along a straight line (such as Figure 3This method not only increases the ventilation area and the heat dissipation area, but also helps to reduce the weight of the contact heat dissipation plate 30 and the liquid-cooled heat dissipation plate 40.

[0041] Furthermore, the heat dissipation principles of the contact type heat dissipation plate 30 and the liquid cooling type heat dissipation plate 40 have their own characteristics, so the configuration methods of the two are also different.

[0042] For example, the contact heat dissipation plate 30 of this embodiment is an aluminum part. The contact heat dissipation plate 30 made of aluminum will have the characteristics of fast heat dissipation and light weight, so it not only ensures the high heat dissipation efficiency of the camera, but also helps to reduce the weight of the camera.

[0043] Similarly, this embodiment provides a liquid-cooled heat dissipation plate 40 including an aluminum plate 41 and a liquid cooling tube 42; the aluminum plate 41 also has the characteristics of high heat dissipation efficiency and light weight, and a ventilation channel 60 is provided on the aluminum plate 41, which also ensures high efficiency during air-cooled heat dissipation; and the liquid cooling tube 42 is filled with coolant, and the liquid cooling tube 42 is respectively abutted against the two opposite surfaces of the aluminum plate 41, and the liquid cooling tube 42 is also abutted against the heat source plate 20, so that liquid cooling heat dissipation is also achieved.

[0044] It should also be pointed out that in order to ensure that the liquid-cooled heat dissipation plate 40 can better obtain heat, in this embodiment, a planar abutment plate 43 is connected to the outer surface of the liquid cooling tube 42 , and the planar abutment plate 43 abuts against the heat source plate 20 .

[0045] On the one hand, since the surface of the planar abutment plate 43 is flat, the planar abutment plate 43 can better fit with the heat source plate 20. On the other hand, the use of the planar abutment plate 43 and the heat source plate 20 in abutment can also ensure that the contact area between the two is large enough; therefore, after adding the planar abutment plate 43, the heat transfer between the heat source plate 20 and the liquid-cooled heat dissipation plate 40 is more efficient and stable.

[0046] Regarding the fan 50, Figure 2 and Figure 3 As shown, in this embodiment, the fan 50 is disposed between the ventilation hole 12 and the ventilation channel 60 , so that the fan 50 can take away the heat in the ventilation channel 60 in time, ensuring that the heat can be discharged through the ventilation hole 12 in time.

[0047] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
