Technical Field

[0001] The utility model belongs to the technical field of circulation detection devices, and in particular relates to a circulation detection device for sensor testing. Background Art

[0002] The sensor cycling tester is designed to evaluate the performance stability and reliability of sensors under varying environmental conditions. By simulating the temperature and humidity fluctuations experienced in actual use, the sensor cycling tester can assess sensor performance in extreme environments, ensuring proper functioning under a wide range of conditions.

[0003] At present, the existing circulation detection device for sensor testing generates a large amount of heat due to long-term use when performing circulation detection on the sensor. Ventilation heat dissipation is generally used to dissipate heat. However, during the heat dissipation process, external dust will enter the interior of the device and adhere to the surface of the components, affecting the heat dissipation of the components themselves, causing the components to overload and reduce the service life of the components. For this reason, we propose a circulation detection device for sensor testing. Utility Model Content

[0004] The purpose of the present utility model is to provide a circulation detection device for sensor testing to solve the existing problems raised in the above background technology.

[0006] Preferably, a sealing plate is fixedly installed at the opening of the heat dissipation slot by gluing, and an air inlet and an exhaust port are respectively provided at both ends of the sealing plate, and a heat dissipation fan is provided inside the air inlet and the exhaust port.

[0007] Preferably, a heat conducting rod is provided on the periphery of the heat conducting plate, and the heat conducting rod is arranged around the heat conducting plate. Both sides of the heat conducting rod are in close contact with the heat conducting plate and the heat dissipation fins respectively.

[0008] Preferably, dustproof nets are provided inside the air inlet and the exhaust port, and the four sides of the dustproof nets are fixedly installed inside the air inlet and the exhaust port by gluing.

[0009] Preferably, a heat insulating layer is filled between the heat conducting plate and the heat dissipating fins, and the heat insulating layer wraps around the periphery of the cooling plate and the heat conducting rod but does not affect the contact between the two and the heat conducting plate and the heat dissipating fins.

[0010] Preferably, an operating table is provided at the bottom of the main body of the circulation detection device, and the operating table is fixedly mounted on the top of the operating table by mounting screws.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. By setting a heat dissipation groove on the back of the main body of the circulation detection device, using a heat conduction plate, cooling plate and heat dissipation fins, the internal heat is transferred to the inside of the heat dissipation groove by heat transfer, and finally the heat is discharged through the cooling fan in the air inlet and exhaust port, thereby achieving the purpose of heat dissipation. This design effectively prevents the entry of external dust while ensuring heat dissipation efficiency.

[0013] 2. By setting a heat conducting rod on the periphery of the cooling plate, the contact area on both sides of the cooling plate is increased, thereby improving the efficiency of heat transfer and achieving the purpose of improving heat dissipation efficiency. By setting a heat insulation layer, the two sides of the cooling plate are isolated to prevent the heat inside the heat dissipation slot from affecting the normal operation of the cooling plate.

[0019] See also Figure 1-3 The utility model provides a technical solution of a circulation detection device for sensor testing: it includes a circulation detection device body 1, a cooling plate 5 and a heat dissipation fin 8. A heat dissipation groove 3 is opened on the back of the circulation detection device body 1, and a heat conduction plate 4 is embedded on one side surface of the inner side of the heat dissipation groove 3. One side of the heat conduction plate 4 is placed inside the shell of the circulation detection device body 1 and contacts the components inside it. The other side of the heat conduction plate 4 is placed inside the heat dissipation groove 3. A cooling plate 5 is provided on one side surface of the heat conduction plate 4 extending to the inside of the heat dissipation groove 3. The heat absorbing end of the cooling plate 5 is fixedly connected to the heat conduction plate 4 by thermal grease, and the heat releasing end of the cooling plate 5 is fixedly connected to the heat dissipation fin 8 by thermal grease. The heat dissipation fin 8 is placed inside the heat dissipation groove 3.

[0020] Specifically, a sealing plate 9 is fixedly installed at the opening of the heat dissipation slot 3 by gluing. An air inlet 10 and an exhaust port 11 are respectively provided at both ends of the sealing plate 9. A heat dissipation fan 12 is provided inside the air inlet 10 and the exhaust port 11.

[0021] Specifically, a heat conducting rod 6 is provided on the outer periphery of the heat conducting plate 4 . The heat conducting rod 6 is arranged around the heat conducting plate 4 . Both sides of the heat conducting rod 6 are in close contact with the heat conducting plate 4 and the heat dissipation fins 8 respectively.

[0022] Specifically, dustproof nets 13 are provided inside the air inlet 10 and the air outlet 11 . The dustproof nets 13 are fixed to the inside of the air inlet 10 and the air outlet 11 by gluing.

[0023] Specifically, a heat insulating layer 7 is filled between the heat conducting plate 4 and the heat dissipating fins 8 , and the heat insulating layer 7 wraps around the periphery of the cooling plate 5 and the heat conducting rod 6 but does not affect the contact between the two and the heat conducting plate 4 and the heat dissipating fins 8 .

[0025] The heat generated by the operation of the internal components of the circulation detection device body 1 is transferred to the interior of the heat dissipation tank 3 through the heat conduction plate 4, and is absorbed by the heat absorption end of the cooling fin 5 on the other side of the heat conduction plate 4, and then released to the heat dissipation fin 8 through the heat release end of the cooling fin 5. At the same time, the heat conduction rod 6 is used to increase the contact area on both sides of the cooling fin 5, thereby improving the efficiency of heat transfer and achieving the purpose of improving the heat dissipation efficiency. The heat dissipation fin 8 then diffuses the absorbed heat to the interior of the heat dissipation tank 3, and finally draws air from the outside through the heat dissipation fan 12 in the air inlet 10, and after being filtered through the dustproof net 13, it is injected into the interior of the heat dissipation tank 3.

This design effectively prevents external dust from entering the shell of the circulation detection device body 1 while dissipating heat.
