Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a camera temperature control device and a camera. Background Technology

[0002] Some cameras operate in extreme high and low temperature environments. At extreme high temperatures, cameras may experience problems such as aging and failure of electronic components and decreased image quality; at extreme low temperatures, camera startup time may be prolonged, or they may even freeze, affecting normal operation.

[0003] In existing technologies, some cameras use semiconductor cooling devices to cool their internal components. However, this method can only cool cameras that operate in high-temperature environments and is relatively expensive. Utility Model Content

[0004] Therefore, it is necessary to provide a camera temperature control device and a camera to address the above problems, so as to achieve cooling or heating of the camera.

[0005] This utility model provides a camera temperature control device for a camera. The camera includes a housing, comprising: a casing for being disposed on the outer side wall of the housing; and a solar panel, comprising an evaporator, a first pipe, an absorber, and a second pipe connected in sequence. The evaporator is used to contain a cooling solution. One of the first pipe and the second pipe is disposed on the side wall of the casing away from the housing, and the other is disposed on the side wall of the housing close to the housing. The solar panel also includes a connecting pipe assembly with both ends respectively connected to the evaporator and the absorber.

[0006] In the aforementioned camera temperature control device, when the first pipe is located on the side wall of the housing away from the outer shell, the low-temperature liquid refrigerant flowing through the second pipe gradually absorbs heat and evaporates into a high-temperature gaseous refrigerant, which can cool the outer shell and interior of the camera, enabling the camera to operate in extreme high-temperature environments and preventing the aging and failure of the camera's electronic components or affecting the camera's image quality. When the first pipe is located on the side wall of the housing close to the outer shell, the high-temperature gaseous refrigerant flowing through the first pipe gradually cools into a low-temperature liquid refrigerant after heat exchange, which can heat the outer shell and interior of the camera, enabling the camera to operate in extreme low-temperature environments or to perform cold start preheating of the camera, preventing the camera from freezing. This camera temperature control device achieves cooling or heating of the camera through the rational conversion of solar energy, which is low-cost, and the stronger the solar radiation, the better the cooling and heating effect of the solar panel on the camera.

[0007] In one embodiment, the solar module further includes a first four-way valve, two of which are connected to the end of the first pipeline near the evaporator, and the other two of which are connected to the end of the second pipeline near the absorber.

[0008] With this setup, the flow direction of the refrigerant in the first and second pipelines can be adjusted by the first four-way valve, so as to achieve the switching of the solar panel for cooling and heating the camera.

[0009] In one embodiment, the solar module further includes a connecting pipe, the two ends of which are respectively connected to the end of the first pipe away from the evaporator and the end of the second pipe away from the absorber, and the connecting pipe is provided with a throttling valve.

[0010] With this configuration, the temperature of the cryogenic liquid refrigerant can be further reduced when it passes through the throttling valve, thereby improving the heat absorption effect of the cryogenic liquid refrigerant in the second pipeline. At the same time, it can also prevent the high-temperature gaseous refrigerant from entering the second pipeline due to incomplete heat exchange in the first pipeline.

[0011] In one embodiment, the solar panel further includes a fan disposed within the housing, the fan being capable of blowing air toward the first conduit and / or the second conduit.

[0012] With this configuration, the fan can provide forced convection when it is working, improving the heat exchange between the first pipe and the external environment, as well as the heat exchange between the second pipe and the outer casing.

[0013] In one embodiment, the solar module further includes a plurality of heat collection pipes in communication with the evaporator, the heat collection pipes being disposed on the side wall of the housing and used to contain a refrigerant solution.

[0014] This configuration increases the area of ​​the refrigerant solution in the heat collection pipe that receives solar radiation, thereby improving the heat absorption and heating effect and efficiency of the refrigerant solution.

[0015] In one embodiment, the evaporator is disposed on the top wall of the housing, and the absorber is disposed on the bottom wall of the housing; the connecting pipe assembly includes a spray pipe and a return pipe, the two ends of the spray pipe are respectively connected to the evaporator and the absorber, the two ends of the return pipe are respectively connected to the absorber and the evaporator, and a pump body is provided on the return pipe.

[0016] With this configuration, the dilute refrigerant in the evaporator can be sprayed into the absorber through the spray pipe under the action of gravity. When the pump is working, it can pump the concentrated refrigerant in the absorber into the evaporator through the return pipe to realize the circulation of the refrigerant in the solar module. The circulation structure is simple and easy to process and assemble.

[0017] In one embodiment, the first conduit and / or the second conduit is configured as a coil.

[0018] This design simplifies the structure of the coil, makes it easy to process and assemble, reduces costs, and increases the contact area between the first and second pipes and the outer casing and external environment, thereby improving heat exchange efficiency.

[0019] In one embodiment, the camera temperature control device further includes a wind power component disposed on the top of the housing. The wind power component includes a vortex tube and a third pipe. The vortex tube is provided with an air inlet, a cold air outlet and a hot air outlet. The third pipe is disposed on a side wall of the housing near the housing and is connected to the cold air outlet or the hot air outlet.

[0020] With this configuration, when the third pipe is connected to the cold air outlet, the cold air flowing from the cold air outlet to the third pipe can cool down the camera's casing and interior; when the third pipe is connected to the hot air outlet, the hot air flowing from the hot air outlet to the third pipe can heat up the camera's casing and interior. This camera temperature control device achieves cooling or heating of the camera through the rational conversion of wind energy, which is low-cost, and the higher the wind energy intensity, the better the cooling and heating effect of the wind energy component on the camera.

[0021] In one embodiment, the wind power assembly further includes a second four-way valve, the four ports of which are respectively connected to the cold air outlet, the hot air outlet, the third pipeline and the outside; and / or, the wind power assembly further includes an air collecting hood connected to the air inlet, the cross-sectional area of ​​which gradually increases from the air inlet toward the end away from the vortex tube.

[0022] With this setup, the third pipe can be connected to either the cold air outlet or the hot air outlet via the second four-way valve, enabling the wind power unit to switch between cooling and heating the camera. The air collector can gather air and accelerate the airflow entering the air inlet, making the airflow entering the vortex tube through the air collector and air inlet a high-speed airflow.

[0023] This utility model embodiment also provides a camera, including a housing and a camera temperature control device as described above.

[0024] This configuration enables the camera to operate in extreme high and low temperature environments. Attached Figure Description

[0034] Some cameras operate in extreme high and low temperature environments. At extreme high temperatures, cameras face problems such as aging and failure of electronic components and decreased image quality; at extreme low temperatures, camera startup time is prolonged, and they may even freeze, affecting normal operation. In existing technologies, some cameras use semiconductor cooling devices to cool their internal components, but this method can only cool cameras operating in high-temperature environments and is costly.

[0035] To solve the above problems, such as Figures 1 to 2 As shown, this utility model provides a camera temperature control device and a camera to achieve cooling or heating of the camera.

[0036] like Figure 1As shown, specifically, the camera temperature control device is used in the camera. The camera includes a housing 4, and the camera temperature control device includes a housing 1 and a solar panel 2. The housing 1 is used to be disposed on the outer wall of the housing 4. The solar panel 2 includes an evaporator 21, a first pipe 23, an absorber 22, and a second pipe 24 connected in sequence. The evaporator 21 is used to contain a refrigerant solution. One of the first pipe 23 and the second pipe 24 is disposed on the side wall of the housing 1 away from the housing 4, and the other is disposed on the side wall of the housing 1 close to the housing 4. The solar panel 2 also includes a connecting pipe group 25 with both ends that can be connected to the evaporator 21 and the absorber 22, respectively.

[0037] The refrigeration solution is a binary solution composed of two substances with different boiling points that can dissolve in each other. The substance with the higher boiling point is the absorbent, and the substance with the lower boiling point is the refrigerant. Examples include ammonia-water absorption refrigeration solutions and water-lithium bromide absorption refrigeration solutions.

[0038] In the camera temperature control device provided in this embodiment of the utility model, the cooling solution in the evaporator 21 heats up after absorbing solar radiation. The refrigerant in the cooling solution absorbs heat and evaporates into a high-temperature liquid refrigerant, which flows into the first pipe 23. The high-temperature gaseous refrigerant exchanges heat in the first pipe 23 and gradually cools into a low-temperature liquid refrigerant, which flows into the second pipe 24. The low-temperature liquid refrigerant gradually absorbs heat in the second pipe 24 and evaporates into a high-temperature gaseous refrigerant, which flows into the absorber 22. At the same time, the concentration of the cooling solution in the evaporator 21 gradually decreases. The dilute cooling solution can flow into the absorber 22 through the connecting pipe group 25 and absorb the high-temperature gaseous refrigerant in the absorber 22 to become a concentrated cooling solution. The concentrated cooling solution can flow back into the evaporator 21 through the connecting pipe group 25 to achieve circulation. When the first pipe 23 is located on the side wall of the housing 1 away from the outer shell 4, and the second pipe 24 is located on the side wall of the housing 1 close to the outer shell 4, the low-temperature liquid refrigerant flowing through the second pipe 24 gradually absorbs heat and evaporates into a high-temperature gaseous refrigerant, which can cool the outer shell 4 and the interior of the camera, enabling the camera to operate in extreme high-temperature environments and preventing the aging and failure of the camera's electronic components or affecting the camera's image quality. When the first pipe 23 is located on the side wall of the housing 1 close to the outer shell 4, and the second pipe 24 is located on the side wall of the housing 1 away from the outer shell 4, the high-temperature gaseous refrigerant flowing through the first pipe 23 gradually cools into a low-temperature liquid refrigerant after heat exchange, which can heat the outer shell 4 and the interior of the camera, enabling the camera to operate in extreme low-temperature environments or to perform cold start preheating of the camera and prevent the camera from freezing. This camera temperature control device achieves cooling or heating of the camera through the rational conversion of solar energy, which is low-cost, and the stronger the solar radiation, the better the cooling and heating effect of the solar panel 2 on the camera. Among them, the coefficient of performance (COP) of solar module 2 can reach 3 or higher, and its cooling efficiency is much higher than that of semiconductor cooling devices; its coefficient of performance (COP) can reach 2 or higher, and its heating efficiency is much higher than that of heating directly using solar energy.

[0039] like Figure 1 As shown, the first pipe 23 and the second pipe 24 are configured as coils. The coil structure is simple, easy to process and assemble, and has a low cost. Furthermore, the user can adjust the shape of the coil according to the structure of the housing 1 and the camera, thereby increasing the contact area between the first pipe 23 and the second pipe 24 and the housing 4 and the external environment, improving the heat exchange effect.

[0040] like Figure 1As shown, in one embodiment, the evaporator 21 is disposed on the top wall of the shell 1, and the absorber 22 is disposed on the bottom wall of the shell 1; the connecting pipe assembly 25 includes a spray pipe 251 and a return pipe 252, the two ends of the spray pipe 251 are respectively connected to the evaporator 21 and the absorber 22, the two ends of the return pipe 252 are respectively connected to the absorber 22 and the evaporator 21, and a pump body 253 is provided on the return pipe 252. The refrigerant solution in evaporator 21 heats up after absorbing solar radiation. The refrigerant in the solution absorbs heat and evaporates into a high-temperature liquid refrigerant, which flows into the first pipe 23. Simultaneously, the concentration of the refrigerant solution in evaporator 21 gradually decreases. The dilute refrigerant solution can be sprayed into absorber 22 through spray pipe 251 under the action of gravity, allowing the sprayed dilute refrigerant solution to better absorb the high-temperature gaseous refrigerant in absorber 22 and become a concentrated refrigerant solution. When pump body 253 is working, it can pump the concentrated refrigerant solution in absorber 22 into evaporator 21 through return pipe 252 to realize the circulation of refrigerant solution in solar module 2. The circulation structure is simple and easy to process and assemble. Of course, in other embodiments, evaporator 21 and absorber 22 can also be set in other positions of housing 1 as needed. The same pipe can be used for the dilute refrigerant solution in evaporator 21 to flow into absorber 22 and the concentrated refrigerant solution in absorber 22 to flow into evaporator 21. The flow direction of cold solution in pipe can be controlled by controlling the forward and reverse rotation of the pump on the pipe.

[0041] like Figure 1As shown, the solar module 2 also includes a first four-way valve 26. Two ports of the first four-way valve 26 are connected to the end of the first pipe 23 near the evaporator 21, and the other two ports are connected to the end of the second pipe 24 near the absorber 22. Thus, the flow direction of the refrigerant in the first pipe 23 and the second pipe 24 can be adjusted by the first four-way valve 26 to switch between cooling and heating the camera using the solar module 2. For ease of description, the following example illustrates the situation where the first pipe 23 is located on the side wall of the housing 1 away from the outer casing 4, and the second pipe 24 is located on the side wall of the housing 1 close to the outer casing 4. When cooling is required for the camera, the refrigerant flows sequentially through the evaporator 21, the first pipe 23, and the second pipe 24 into the absorber 22. This allows the low-temperature liquid refrigerant flowing through the second pipe 24 to gradually absorb heat and evaporate into a high-temperature gaseous refrigerant, thus cooling the outer casing 4 and the interior of the camera. When heating is required for the camera, the refrigerant solution in the evaporator 21 absorbs solar radiation and heats up. The refrigerant in the refrigerant solution absorbs heat and evaporates into a high-temperature liquid state. The refrigerant flows to the end of the first pipe 23 connected to the evaporator 21. The high-temperature gaseous refrigerant flows into the second pipe 24 through the first four-way valve 26. After exchanging heat with the outer casing 4 in the second pipe 24, it gradually cools into a low-temperature liquid refrigerant and flows back to the first pipe 23. The low-temperature liquid refrigerant gradually absorbs heat and evaporates into a high-temperature gaseous refrigerant in the first pipe 23. It then flows into the end of the second pipe 24 connected to the absorber 22 through the first four-way valve 26 and finally into the absorber 22. Thus, the high-temperature gaseous refrigerant flowing through the second pipe 24 can heat the outer casing 4 and the interior of the camera by gradually cooling into a low-temperature liquid refrigerant after exchanging heat with the outer casing 4.

[0042] like Figure 1 As shown, the solar module 2 also includes a connecting pipe 27, with its two ends connected to the end of the first pipe 23 away from the evaporator 21 and the end of the second pipe 24 away from the absorber 22, respectively. A throttling valve 271 is installed on the connecting pipe 27. When cooling the camera, the high-temperature gaseous refrigerant gradually cools into a low-temperature liquid refrigerant after heat exchange in the first pipe 23 and flows through the connecting pipe 27 to the second pipe 24. The low-temperature liquid refrigerant's temperature is further reduced by the throttling valve 271, improving its heat absorption effect in the second pipe 24. This also prevents incomplete heat exchange in the first pipe 23 from causing some of the high-temperature gaseous refrigerant to enter the second pipe 24.

[0043] like Figure 1As shown, the solar panel 2 also includes a fan 28 disposed within the housing 1. In one embodiment, there are two fans 28, one of which blows air towards the first pipe 23, and the other blows air towards the second pipe 24. When the fans 28 are working, they can provide forced convection, improving the heat exchange effect between the first pipe 23 and the external environment, as well as the heat exchange effect between the second pipe 24 and the housing 4, thereby improving the cooling and heating effect on the camera without occupying too much space within the housing 1. Of course, in other embodiments, there can also be only one fan 28, which blows air towards either the first pipe 23 or the second pipe 24, or the number of fans 28 can be set to three, four, or more as needed.

[0044] like Figures 1 to 2 As shown, the solar module 2 also includes multiple heat collection pipes 29 connected to the evaporator 21. These heat collection pipes 29 are located on the side wall of the outer casing 4 and are used to contain the refrigerant solution. Before the solar module 2 operates, the refrigerant solution is contained within the heat collection pipes 29. After absorbing solar radiation, the refrigerant solution in the heat collection pipes 29 heats up and converges in the evaporator 21. The refrigerant solution in the evaporator 21 continues to absorb solar radiation and heats up. The refrigerant in the refrigerant solution absorbs heat and evaporates into a high-temperature liquid refrigerant, which flows into the first pipe 23. After the solar module 2 operates, the concentrated refrigerant solution in the evaporator 21 returns to the heat collection pipes 29. The side wall area of ​​the outer casing 4 is larger than that of the evaporator 21, thereby increasing the area of ​​the refrigerant solution in the heat collection pipes 29 that receives solar radiation, improving the heat absorption and heating effect and efficiency of the refrigerant solution, and thus improving the cooling and heating effect of the solar module 2 on the camera. In this embodiment, heat collection pipes 29 can be provided on one, two, three or four side walls of the outer casing 4, and multiple heat collection pipes 29 can be provided on each side wall at intervals, as long as it does not affect the normal operation of the camera. No specific limitation is made here.

[0045] like Figure 1As shown, the camera temperature control device also includes a wind power component 3 located on the top of the housing 4. The wind power component 3 includes a vortex tube 32 and a third pipe 33. The vortex tube 32 has an air inlet 321, a cold air outlet 322, and a hot air outlet 323. The third pipe 33 is located on one side wall of the housing 1 near the housing 4 and is connected to the cold air outlet 322 or the hot air outlet 323. After the outside air enters the vortex tube 32 through the air inlet 321, it forms a free vortex inside the vortex tube 32. The angular velocities between the free vortex layers are different, generating frictional heat transfer, thereby achieving energy separation. The temperature of the airflow in the middle layer decreases, and a cold airflow with a lower temperature than the ambient temperature is drawn out from the cold air outlet 322 of the vortex tube 32. The temperature of the airflow in the outer layer increases, and a hot airflow with a higher ambient temperature is drawn out from the hot air outlet 323 of the vortex tube 32. When the third pipe 33 is connected to the cold air outlet 322, the cold air flowing from the cold air outlet 322 to the third pipe 33 can cool the camera's outer casing 4 and its interior, enabling the camera to operate in extreme high-temperature environments and preventing the camera's electronic components from aging and failing or affecting the camera's image quality. When the third pipe 33 is connected to the hot air outlet 323, the hot air flowing from the hot air outlet 323 to the third pipe 33 can heat the camera's outer casing 4 and its interior, enabling the camera to operate in extreme low-temperature environments or to perform cold start preheating of the camera, preventing the camera from freezing. This camera temperature control device achieves cooling or heating of the camera through the rational conversion of wind energy, with low cost, and the higher the wind energy intensity, the better the cooling and heating effect of the wind energy component 3 on the camera.

[0046] like Figure 1 As shown, the third pipe 33 is configured as a coil. The coil has a simple structure, is easy to manufacture and assemble, and has a low cost. Furthermore, the user can adjust the shape of the coil according to the structure of the housing 1 and the camera, thereby increasing the contact area between the third pipe 33 and the outer casing 4 and improving the heat exchange effect. The third pipe 33 can be staggered with the second pipe 24 to ensure the contact area between the third pipe 33 and the second pipe 24 and the outer casing 4, while avoiding interference between the third pipe 33 and the second pipe 24.

[0047] like Figure 1As shown, the wind power unit 3 also includes a second four-way valve 34. The four ports of the second four-way valve 34 are respectively connected to the cold air outlet 322, the hot air outlet 323, the third pipe 33, and the outside environment. Thus, the connection between the third pipe 33 and the cold air outlet 322 or the hot air outlet 323 can be adjusted via the second four-way valve 34 to switch between cooling and heating the camera. When cooling the camera is required, the second four-way valve 34 is adjusted so that the cold air outlet 322 is connected to the third pipe 33, and the hot air outlet 323 is connected to the outside environment; when heating the camera is required, the second four-way valve 34 is adjusted so that the hot air outlet 323 is connected to the third pipe 33, and the cold air outlet 322 is connected to the outside environment.

[0048] like Figure 1 As shown, the wind power assembly 3 also includes a wind collector shroud 31 connected to the air inlet 321. The cross-sectional area of ​​the wind collector shroud 31 gradually increases from the air inlet 321 toward the end away from the vortex tube 32. The wind collector shroud 31 can concentrate the wind, and according to the Venturi effect, the airflow velocity is inversely proportional to the cross-sectional area of ​​the flow path. Therefore, the wind collector shroud 31 can also accelerate the airflow entering the air inlet 321, making the airflow entering the vortex tube 32 through the wind collector shroud 31 and the air inlet 321 a high-speed airflow, further improving the cooling and heating effect of the wind power assembly 3 on the camera.

[0049] like Figure 1 As shown, this embodiment of the utility model also provides a camera, including a housing 4 and the aforementioned camera temperature control device. Specifically, the camera also includes a lens (not shown) and other electronic components disposed within the housing 4. Preferably, the housing 1 is disposed on the rear side wall of the housing 4 to ensure cooling and heating effects while avoiding interference with the normal shooting of the lens. The camera temperature control device can achieve cooling or heating of the camera through the rational conversion of solar and wind energy, enabling the camera to operate in extreme high and low temperature environments.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
