Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a protective heat dissipation device for an outdoor depth camera, comprising a protective shell 1 and a support frame 2. A back cover 10 is installed on one side of the protective shell 1, a heat dissipation block 6 is installed at the bottom of the inner wall of the protective shell 1, and an air outlet fan 61 is fixedly installed on the inner wall of the heat dissipation block 6. An aluminum plate 7 is installed on the outside of the heat dissipation block 6 and located on the inner wall of the protective shell 1, and a copper plate 8 is installed on the outside of the aluminum plate 7 and located on the inner wall of the protective shell 1. At the same time, a silicone plate 9 is installed on one side of the aluminum plate 7 and the copper plate 8. Positioning grooves 4 are provided on the left and right sides of the protective shell 1, bolts 5 are installed inside the two positioning grooves 4, and threaded holes 23 are provided on the left and right ends of the top of the support frame 2, the bolts 5 are sleeved on the inner walls of the threaded holes 23, and a fin 21 is fixedly installed on the top of the support frame 2, and pads 22 are fixedly installed on the left and right sides of the fin 21 and located on the top of the support frame 2. At the same time, a DC fan 11 is installed on the top of the support frame 2 and at the bottom of the fin 21.

[0023] The heat dissipation block 6, aluminum plate 7, copper plate 8 and silicone plate 9 can be installed respectively through the protective shell 1 and the support frame 2. Since the inner wall of the heat dissipation block 6 is fixedly installed with an air outlet fan 61, starting the air outlet fan 61 can accelerate the internal air circulation of the protective shell 1. Since the aluminum plate 7, copper plate 8 and silicone plate 9 all have good thermal conductivity, the protective shell 1 can be dissipated when the outdoor temperature is too high. The protective shell 1 can be installed through the support frame 2. Since the top of the support frame 2 is fixedly installed with fins 21, pads 22 are fixedly installed on the left and right sides of the fins 21 and located at the top of the support frame 2. At the same time, a DC fan 11 is installed on the top of the support frame 2 and at the bottom of the fins 21. Therefore, the fins 21 can flow the heat of the protective shell 1 from the temperature gradient to the fins 21, and by starting the DC fan 11, the DC fan 11 can accelerate the heat dissipation rate of the fins 21, thereby avoiding the high heat inside the protective shell 1 causing the camera life to be shortened, the structural parts to be burned, and the structural parts to be deformed.

[0024] See Figure 1 、 Figure 2 The upper and lower ends of the protective shell 1 are both provided with heat dissipation vents 3, and the upper and lower ends of the heat dissipation block 6 are both provided with heat dissipation vents 2 62. At the same time, the heat dissipation vents 1 3 and the heat dissipation vents 2 62 are kept overlapped. The heat dissipation block 6 is installed on the inner wall of the protective shell 1, and the air outlet fan 61 is fixedly installed on the inner wall of the heat dissipation block 6. At the same time, a triangular block is installed on the inner wall of the heat dissipation block 6 and on the top of the air outlet fan 61.

[0025] The heat sink 6 can be installed through the protective shell 1. Since the upper and lower ends of the heat sink 6 are provided with heat dissipation ports 2 62, and the air outlet fan 61 is fixedly installed on the inner wall of the heat sink 6, a triangular block is installed on the inner wall of the heat sink 6 and on the top of the air outlet fan 61, thereby driving the air outlet fan 61. The air outlet of the air outlet fan 61 can dissipate heat to the inner wall of the protective shell 1 through the triangular block, and since the heat dissipation port 1 3 and the heat dissipation port 2 62 remain overlapped, the circulation of air inside the protective shell 1 and the external air can be accelerated.

[0026] See Figure 1 、 Figure 3 The fin 21 is located at the bottom of the protective shell 1 and is in contact with the heat dissipation port 3 opened at the bottom of the protective shell 1. At the same time, the two pads 22 are in contact with the bottom of the protective shell 1. There are three DC fans 11, and the three DC fans 11 are all installed on the top of the support frame 2 and are located at the bottom of the fin 21.

[0027] The three DC fans 11, the fins 21 and the two pads 22 can be installed through the support frame 2. The two pads 22 are in contact with the bottom of the protective shell 1, thereby supporting the protective shell 1. Since the fins 21 are located at the bottom of the protective shell 1 and are in contact with the heat dissipation port 3 opened at the bottom of the protective shell 1, when the outdoor temperature is too high, the fins 21 can flow the heat inside the protective shell 1 to the fins 21 through the temperature gradient. By driving the three DC fans 11, the three DC fans 11 can accelerate the heat dissipation efficiency of the fins 21 on the protective shell 1, thereby avoiding the problems of shortening the camera life, burning of structural parts and deformation of structural parts caused by high heat inside the protective shell 1.

[0028] See Figure 3 、 Figure 4 A rectangular notch is provided at the bottom of the support frame 2, and a filter 12 is installed inside the rectangular notch. At the same time, the bottoms of the three DC fans 11 are in contact with the bottom of the rectangular notch. The air outlets of the three DC fans 11 are located at the top of the support frame 2, and the air exhaust ports of the three DC fans 11 are located at the bottom of the support frame 2.

[0029] The filter 12 can be installed through the rectangular slot opened at the bottom of the support frame 2. Since the air outlets of the three DC fans 11 are located at the top of the support frame 2, and the air exhaust ports of the three DC fans 11 are located at the bottom of the support frame 2, when the temperature inside the protective shell 1 is too high, the three DC fans 11 are driven, and the three DC fans 11 can accelerate the efficiency of the fins 21 in dissipating heat to the protective shell 1. Moreover, through the filter 12, it can prevent the three DC fans 11 from working, and prevent tiny particles such as dust, hair, and dandruff from entering the interior of the protective shell 1, causing the heat dissipation holes and heat sinks to be blocked.

[0030] During operation, the heat dissipation block 6, aluminum plate 7, copper plate 8 and silicone plate 9 can be installed respectively through the protective shell 1 and the support frame 2. Since the inner wall of the heat dissipation block 6 is fixedly installed with an air outlet fan 61, starting the air outlet fan 61 can accelerate the internal air circulation of the protective shell 1. Since the aluminum plate 7, copper plate 8 and silicone plate 9 all have good thermal conductivity, the protective shell 1 can be dissipated when the outdoor temperature is too high. The protective shell 1 can be installed through the support frame 2. Since the top of the support frame 2 is fixedly installed with fins 21, pads 22 are fixedly installed on the left and right sides of the fins 21 and located at the top of the support frame 2. At the same time, a DC fan 11 is installed on the top of the support frame 2 and at the bottom of the fins 21, so that the fins 21 can flow the heat of the protective shell 1 from the temperature gradient to the fins 21, and by starting the DC fan 11, the DC fan 11 can accelerate the heat dissipation rate of the fins 21, thereby avoiding the high heat inside the protective shell 1 causing the camera life to be shortened, the structural parts to be burned and the structural parts to be deformed.

[0031] The heat sink 6 can be installed through the protective shell 1. Since the upper and lower ends of the heat sink 6 are provided with heat dissipation ports 2 62, and the air outlet fan 61 is fixedly installed on the inner wall of the heat sink 6, a triangular block is installed on the inner wall of the heat sink 6 and on the top of the air outlet fan 61, thereby driving the air outlet fan 61. The air outlet of the air outlet fan 61 can dissipate heat to the inner wall of the protective shell 1 through the triangular block, and since the heat dissipation port 1 3 and the heat dissipation port 2 62 remain overlapped, the circulation of air inside the protective shell 1 and the external air can be accelerated.

[0032] The three DC fans 11, the fins 21 and the two pads 22 can be installed through the support frame 2. The two pads 22 are in contact with the bottom of the protective shell 1, thereby supporting the protective shell 1. Since the fins 21 are located at the bottom of the protective shell 1 and are in contact with the heat dissipation port 3 opened at the bottom of the protective shell 1, when the outdoor temperature is too high, the fins 21 can flow the heat inside the protective shell 1 to the fins 21 through the temperature gradient. By driving the three DC fans 11, the three DC fans 11 can accelerate the heat dissipation efficiency of the fins 21 on the protective shell 1, thereby avoiding the problems of shortening the camera life, burning of structural parts and deformation of structural parts caused by high heat inside the protective shell 1.

[0033] The filter 12 can be installed through the rectangular slot opened at the bottom of the support frame 2. Since the air outlets of the three DC fans 11 are located at the top of the support frame 2, and the air exhaust ports of the three DC fans 11 are located at the bottom of the support frame 2, when the temperature inside the protective shell 1 is too high, the three DC fans 11 are driven, and the three DC fans 11 can accelerate the efficiency of the fins 21 in dissipating heat to the protective shell 1. Moreover, through the filter 12, it can prevent the three DC fans 11 from working, and prevent tiny particles such as dust, hair, and dandruff from entering the interior of the protective shell 1, causing the heat dissipation holes and heat sinks to be blocked.

[0034] In summary, the fins 21 of the device are installed at the bottom of the protective shell 1, so that the heat inside the protective shell 1 can flow to the fins 21 through the temperature gradient, and by driving three DC fans 11, the three DC fans 11 can accelerate the heat dissipation efficiency of the fins 21 to the protective shell 1, thereby avoiding the problems of shortening the camera life, burning of structural parts and deformation of structural parts caused by high heat inside the protective shell 1.
