Description

Technical Field

[0001] This utility model relates to the field of camera heat dissipation technology, and more specifically, to a heat dissipation device for a fire monitoring camera. Background Technology

[0002] In relatively enclosed spaces where there are heat sources and fire hazards inside the equipment room, surveillance cameras are usually installed to monitor for open flames inside the equipment room. This allows operators and managers to detect the fires in a timely manner and take appropriate measures to prevent major fire accidents.

[0003] However, traditional cameras do not have effective heat dissipation capabilities and are not suitable for the above-mentioned situations. Therefore, how to provide a camera heat dissipation device that can adapt to the above-mentioned situations is an urgent problem to be solved in this field. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation device for fire monitoring cameras to solve the problem that traditional cameras do not have a strong heat dissipation function.

[0005] This utility model is achieved through the following technical solution:

[0006] A heat dissipation device for a fire monitoring camera includes a housing installed on the side wall of an equipment room. A monitoring window is located on the side of the housing facing the equipment room. The camera is installed inside the housing and monitors the interior of the equipment room through the monitoring window. An air inlet is located on the side of the housing opposite the monitoring window, and an exhaust window is located on each of the two adjacent opposite sides of the housing. Each exhaust window is equipped with an exhaust fan for expelling air from inside the housing to the outside. The exhaust fans draw cool air from outside through the air inlet into the housing to cool the camera and expel hot air from the housing, thus achieving heat dissipation for the camera. This device can be used in relatively enclosed environments where there are heat sources inside the equipment room and fire hazards.

[0007] Optionally, the exhaust window is provided with heat dissipation fins, which increase the heat exchange area inside the shell and facilitate improved heat dissipation efficiency. The heat dissipation fins include a base plate and a number of fins spaced apart on one side of the base plate. The base plate is fixedly connected to the shell, and the fins face the exhaust fan. The grooves between adjacent fins are all connected to the air inlet, which can effectively reduce wind resistance.

[0008] Optionally, a gap is left between one end of the heat dissipation fins and the side wall of the housing where the air inlet is located.

[0009] Optionally, one end of the heat dissipation fins abuts against the side wall of the housing where the air inlet is located, and the air inlet can cover all the grooves between adjacent fins.

[0010] Optionally, the monitoring window is equipped with transparent heat-insulating glass, which can effectively isolate the internal heat source of the equipment room and reduce the internal temperature of the casing while monitoring is being carried out.

[0011] Optionally, the air inlet is equipped with louvers, which can reduce the entry of dust and prevent larger debris from being sucked into the housing, thus avoiding affecting the heat dissipation effect.

[0012] Optionally, the housing has a cable outlet on the side adjacent to the monitoring window.

[0013] Optionally, the air inlet is circular in shape.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0015] 1. In this utility model, by setting two exhaust fans, external cold air can be drawn into the housing from the air inlet to cool the camera, and hot air can be discharged to the outside of the housing to achieve heat dissipation of the camera. Traditional cameras can be used in relatively enclosed places where there are heat sources inside the equipment room and fire hazards.

[0016] 2. In this utility model, the exhaust window is provided with heat dissipation fins, which increases the heat exchange area inside the shell and facilitates the improvement of heat dissipation efficiency. Moreover, the fins face the exhaust fan and the grooves between adjacent fins are connected to the air inlet, which can effectively reduce wind resistance.

[0017] 3. In this utility model, a louver is provided at the air inlet. It is easy to understand that the louver is composed of several blades with the same tilt angle. The gap between adjacent blades is small, which can reduce the entry of dust and at the same time, it is easy to block larger debris from being sucked into the housing, thus avoiding affecting the heat dissipation effect.

[0018] 4. In this utility model, the monitoring window is equipped with transparent heat-insulating glass, which can effectively isolate the internal heat source of the equipment room and reduce the internal temperature of the casing while monitoring is achieved. Attached Figure Description

[0025] Example 1

[0026] refer to Figures 1-4 A heat dissipation device 100 for a fire monitoring camera includes a housing 1. In practical applications, refer to... Figure 5 Mounting holes are provided on the side wall of the equipment room 200, and the housing 1 is installed at the mounting holes (it should be understood that the housing 1 is located on the outside of the side wall of the equipment room 200). A monitoring window 101 is provided on the side of the housing 1 facing the equipment room 200. The camera 2 is installed inside the housing 1 and monitors the inside of the equipment room 200 through the monitoring window 101. In this embodiment, a transparent heat-insulating glass (not shown in the figure) is provided in the monitoring window 101, which facilitates monitoring while effectively isolating the heat source inside the equipment room 200 and reducing the internal temperature of the housing 1.

[0027] An air inlet 102 is provided on the side of the housing 1 opposite to the monitoring window 101. An exhaust window is provided on each of the two adjacent opposite sides of the housing 1 and the monitoring window 101. An exhaust fan 3 is provided in the exhaust window. The two exhaust fans 3 can draw cold air from the outside into the housing 1 through the air inlet 102 to cool the camera 2 and exhaust hot air out of the housing 1 to achieve heat dissipation of the camera 2. The traditional camera 2 can be used in relatively enclosed places where there are heat sources inside the equipment room 200 and fire hazards.

[0028] The housing 1 has a cable outlet 104 on the side adjacent to the monitoring window 101. All cables (i.e., the cable of the camera 2 and the cable of the exhaust fan 3) are led out from the cable outlet 104. In some embodiments, the cable outlet 104 is located on the lower side of the housing 1 to prevent dust from falling into the cable outlet 104. In some embodiments, the cable outlet 104 is located on other sides of the housing 1 and dustproof measures are taken at the cable outlet 104.

[0029] The exhaust window is equipped with heat dissipation fins 5, which increases the heat exchange area inside the housing 1 and facilitates improved heat dissipation efficiency. Furthermore, the heat dissipation fins 5 include a base plate 501 and a plurality of fins 502 spaced apart on one side of the base plate 501. The base plate 501 is fixedly connected to the housing 1 (e.g., bonded). The fins 502 face the exhaust fan 3 and the grooves between adjacent fins 502 are all connected to the air inlet 102, which can effectively reduce wind resistance.

[0030] Alternatively, in this embodiment, the grooves between adjacent fins 502 are all connected to the air inlet 102 as follows: a gap is left between one end of the heat dissipation fin 5 and the side wall of the housing 1 where the air inlet 102 is located (see reference). Figure 4 ).

[0031] refer to Figure 1 In this embodiment, the air inlet 102 is provided with louvers 4. It is worth noting that the louvers are composed of several blades with the same tilt angle. The gap between adjacent blades is small, which can reduce the entry of dust and at the same time, it is easy to block larger debris from being sucked into the housing 1, so as to avoid affecting the heat dissipation effect.

[0032] Furthermore, in the accompanying drawings, the monitoring window on the housing is rectangular, while the air inlet, air outlet, and cable outlet are all circular. It is easy to understand that the shapes shown in the figures are just one option, not a limitation. In other embodiments, the monitoring window, air inlet, air outlet, and cable outlet can of course also adopt other shapes.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the grooves between adjacent fins 502 are connected to the air inlet 102 in a different way. In this embodiment, one end of the heat dissipation fin 5 abuts against the side wall of the housing 1 where the air inlet 102 is located, and the air inlet 102 can cover all the grooves between adjacent fins 502. That is, on the projection plane perpendicular to the line connecting the monitoring window 101 and the air inlet 102, all the grooves between adjacent fins 502 are located in the air inlet 102.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
