Description
Technical Field
[0001] The present invention relates to the technical field of cameras with heat dissipation function, in particular to a camera with heat dissipation function. Background Art
[0002] A camera is a video input device that is widely used in real-time monitoring and other aspects. Cameras can be divided into two categories: digital cameras and analog cameras. Cameras generally have basic functions such as video recording / transmission and static image capture. After the lens captures the image, the photosensitive component circuit and control components in the camera process the image and convert it into a digital signal that can be recognized by the computer. It is then input into the computer through the parallel port and the image is restored by the software.
[0003] With the continuous development of society, the monitoring clarity of cameras is getting higher and higher, so the image data that needs to be processed and the transmission data are also getting larger and larger. Therefore, a large amount of heat will be generated when the processor processes a large amount of data and reads and writes the data. A Chinese patent discloses a gun-type camera with a heat dissipation function (publication number: CN111741205B). The patent can drive the heat dissipation fan blades to rotate after the heat dissipation motor is started. When the heat dissipation fan blades rotate, air can be pumped from the air inlet into the hose, transmitted from the left side of the bottom of the camera to the right side, and then turned upward from right to left, and then discharged from the air outlet, so that the gas is in contact with the camera for a longer time, and the heat on the camera can be better taken away, but the cooling effect of it only by air cooling is limited.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] See also Figure 1-Figure 5As shown, the present invention is a camera with heat dissipation function, comprising a shell 1, a camera 10 located in the shell 1 and a mounting frame 3 installed on the wall, the mounting frame 3 is hollow, the bottom of the mounting frame 3 is fixedly connected with a connecting block 2, the top of the shell 1 is fixedly connected with a connecting plate 4 for connecting the mounting frame 3, the inner surface of the shell 1 is fixedly connected with a support ring 6, the top of the support ring 6 is fixedly connected with a plurality of support rods 7, a mounting plate 8 for placing a circuit board is fixedly connected between the tops of the plurality of support rods 7, the support ring 6 and the mounting plate 8 are connected by the support rods 7, and a space for air circulation can be formed between the mounting plate 8 and the support ring 6, two connecting pipes 15 are arranged in the shell 1, the bottom ends of the two connecting pipes 15 are connected with a heat absorbing block 5 for absorbing heat, the heat absorbing block 5 is used to press on the chip and memory particles on the circuit board, and the top end of the connecting pipe 15 on one side passes through the shell 1 and is connected with a heat dissipation pipe 17 , the heat dissipation pipe 17 can be made of metal material with good heat dissipation effect. A circulating pump 16 is fixedly connected to the top of the inner cavity of the shell 1. One end of the connecting pipe 15 located on the other side is connected to the water inlet end of the circulating pump 16. The water outlet end of the circulating pump 16 is connected to one end of the heat dissipation pipe 17 through an extension pipe, and a control valve body can be set at the connection to avoid the mixing of heated coolant and unheated coolant. When the coolant that has absorbed heat needs to be replaced, the circulating pump 16 and the control valve body can be opened. The heat dissipation pipe 17 and the connecting pipe 15 are filled with coolant. The outer surface of the heat dissipation pipe 17 is fixedly connected with a plurality of heat dissipation fins 18. The surface of the heat dissipation fins 18 is fixedly connected to the inner surface of the mounting frame 3. The surface of the mounting frame 3 is provided with a plurality of heat dissipation holes 19 for ventilation. The heat on the heat dissipation fins 18 can be dissipated through the heat dissipation holes 19. Through this structure, the heat in the shell 1 can be absorbed and sent to the outside of the shell 1 for heat dissipation.
[0027] In order to make the heat absorbing block 5 as close as possible to the chips and memory particles on the circuit board that generate more heat, a plurality of threaded holes 14 are provided through the top of the mounting plate 8, and the front and back sides of the heat absorbing block 5 are fixedly connected with mounting sleeves 12, and the inner surface of the mounting sleeve 12 is provided with connecting bolts 13, and the outer surface of the connecting bolts 13 is threadedly connected to the inner surface of the threaded hole 14.
[0028] In order to further improve the heat dissipation effect, a plurality of ventilation holes 11 are opened on the surface of the shell 1, and a filter 20 for blocking dust is provided on the inner surface of the ventilation hole 11. A heat dissipation fan 29 is fixedly connected to the inner surface of the shell 1 and located on one side of the ventilation hole 11, and the hot air in the shell 1 is sent to the outside through the heat dissipation fan 29.
[0029] In order to introduce external airflow into the interior of the shell 1, a plurality of limit columns 22 are fixedly connected to the circumference of the inner wall of the shell 1, a connecting ring 23 is slidably connected to the inner surface of the shell 1, and the inner surface of the connecting ring 23 is rotatably connected to the surface of the camera 10. A servo motor 9 for driving the camera 10 to rotate is fixedly connected to the bottom of the mounting plate 8. A plurality of sliding grooves 24 are provided on the outer surface of the connecting ring 23. The inner surface of the sliding groove 24 is slidably connected to the outer surface of the limit column 22. Both sides of the bottom of the support ring 6 are fixedly connected to electric telescopic rods. 21, the output end of the electric telescopic rod 21 is fixedly connected to the top of the connecting ring 23 through a hanging plate, and a rotating groove 25 is provided on the inner surface of the connecting ring 23. The inner surface of the rotating groove 25 is slidably connected to the surface of the camera 10. The surface of the camera 10 is arranged in a stepped shape. Since the surface of the camera 10 is gradually deformed, when the electric telescopic rod 21 is shortened, a gap is formed between the connecting ring 23, the camera 10 and the surface of the housing 1, and air can enter from the gap. When the cooling fan 29 rotates, it can introduce air at normal temperature outside the housing 1.
[0030] In order to increase the height of the connecting ring 23 without affecting the rotation of the camera 10, a connecting sleeve 26 is fixedly connected to the top of the camera 10, and limiting grooves 28 are provided on both sides of the inner wall of the connecting sleeve 26. A fixing bar 27 is slidably connected to the inner surface of the limiting groove 28, and one side of the fixing bar 27 is fixedly connected to the surface of the output end of the servo motor 9. When the connecting ring 23 moves upward, the fixing bar 27 on the output end of the servo motor 9 can slide inside the connecting sleeve 26. At this time, the rotation of the servo motor 9 can still drive the camera 10 to rotate on the inner surface of the rotating groove 25.
[0031] The heat absorption block 5 includes a hollow plate 51, and a plurality of partition plates 52 for separating water flows are staggeredly arranged on the inner surface of the hollow plate 51. The partition plates 52 form flow channels inside the hollow plate 51, thereby avoiding excessive mixing when replacing the hot coolant with the coolant at normal temperature.
[0032] The working principle of the present invention is as follows: during installation, the circuit board is fixed on the mounting plate 8, and then the heat absorbing block 5 is placed on the chips and memory particles where the heat of the circuit board is concentrated. At this time, the connecting bolts 13 are sequentially passed through the inside of the mounting sleeve 12 and the threaded hole 14, and pressed on the top of the circuit board. When the camera 10 needs to rotate, the rotation of the servo motor 9 is controlled at this time. Due to the limiting relationship between the fixing bar 27 and the limiting groove 28, the camera 10 is driven to rotate, thereby obtaining video information from multiple angles. When the surface of the circuit board generates more heat, the internal coolant of the hollow plate 51 can absorb the heat from the surface of the circuit board, thereby taking away part of the heat from the chips and memory particles. When the temperature of the coolant inside the hollow plate 51 rises, the circulating pump 16 is started at this time to pump the coolant in the hollow plate 51 to the inside of the heat dissipation pipe 17, and the original coolant in the heat dissipation pipe 17 is evenly injected into the hollow plate through the connecting pipe 15 on one side and the partition plate 52. 51, absorbs heat again, and the high-temperature coolant in the heat pipe 17 is on the surface of the heat dissipation fins 18 and dissipated through the heat dissipation holes 19. At the same time, the heat dissipation fan 29 is started to blow out the heat accumulated on the surface of the circuit board through the ventilation holes 11. When the camera 10 needs to be cooled quickly, the connecting ring 23 can be driven to move upward inside the shell 1 by shortening the electric telescopic rod 21, and the limiting column 22 slides on the surface of the sliding groove 24. At this time, the connecting sleeve 26 also slides on the output end surface of the servo motor 9, thereby retracting the camera 10 into the shell 1. At this time, a gap is generated between the connecting ring 23, the camera 10 and the shell 1, so that when the heat dissipation fan 29 cools the inside of the shell 1, an air flow circulating with the outside is generated. At this time, the gap generated between the connecting ring 23, the camera 10 and the shell 1 is an air inlet, and enters the shell 1 in an upward manner to bring out the hot air of the shell 1, thereby better dissipating the heat inside the shell 1.
[0033] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
