Description

Technical Field

[0001] The utility model relates to an infrared detection and capture device, in particular to a multi-layer structure micro-infrared detection and capture device, belonging to the technical field of infrared detection. Background Art

[0002] The multi-layer structure micro-infrared detection and capture device is a device with advanced technology, which uses a multi-layer structure to achieve efficient detection and capture of infrared radiation. Generally, its working principle involves the following aspects: through specific material and structure design, selective absorption and detection of infrared radiation with different wavelengths are carried out. When infrared radiation irradiates the detector, the sensitive materials in the multi-layer structure will undergo physical or chemical changes, thereby generating electrical signals or other measurable responses. These responses are processed and analyzed to determine information such as the intensity and wavelength of the infrared radiation;

[0003] For example, in the prior art, the invention with the application number 202111192789.1 discloses a preparation method of a multi-layer structure infrared microbridge detector and an infrared microbridge detector, which realizes the integrated preparation of a CMOS measurement circuit system and a CMOS infrared sensing structure on a CMOS production line by using CMOS technology. Compared with MEMS technology, CMOS does not have process compatibility problems, solves the technical difficulties faced by MEMS technology, and using a CMOS production line process to prepare an infrared microbridge detector can also reduce transportation costs and reduce risks caused by transportation and other problems; the infrared microbridge detector prepared by the integrated CMOS process can achieve the goals of high chip yield, low cost, high production capacity and large-scale integrated production, providing a broader application market for the infrared microbridge detector.

[0004] The similar applications currently have the following deficiencies:

[0005] During use, heat dissipation is carried out through the air holes on the detector housing, and it cannot dissipate heat quickly independently. Excessive temperature will affect the sensitivity and accuracy of the detector, and the sensitive materials and electronic components in the infrared detector may undergo performance changes at high temperatures, resulting in inaccurate detection results;

[0006] Therefore, a multi-layer structure micro-infrared detection and capture device is designed to optimize the above problems. Content of the Utility Model

In addition, a rubber telescopic tube is provided at the exhaust port of the cooling fan, which can directly guide the discharged hot air to the outside of the equipment box through the rubber telescopic tube, and the heat dissipation effect is better. By arranging a positioning mechanism composed of a fixed block, a slider, a fastening screw and a rectangular frame plate at the end of the rubber telescopic tube on the top of the fixing plate, the use length of the rubber telescopic tube can be adjusted during the use process, and the end of the rubber telescopic tube is aligned with the exhaust port to ensure the discharge effect of the hot air.

[0026] General working principle: During use, the catcher body 1 is installed inside the housing, and heat dissipation holes are provided on the housing. When the device is in operation, the cooling fan 7 starts simultaneously to accelerate the air exchange rate inside and outside the housing. At the same time, the heat generated by the catcher body 1 is transferred to the heat sink 4 by means of contact transfer, and the flowing air takes away the heat on the surface of the heat sink 4. By using the methods of contact heat dissipation and air cooling heat dissipation, the temperature of the catcher body 1 is reduced simultaneously, ensuring the stable operation of the catcher body 1.

[0027] In this embodiment, the fixing assembly includes a fixing plate 10 and rubber columns 11. The fixing plate 10 is arranged in parallel at the bottom of the mounting plate 2, and rubber columns 11 are fixed between the four corners of the top of the fixing plate 10 and the mounting plate 2.

By using the positioning mechanism 9, the discharge port of the rubber telescopic tube 8 is directly aligned with the heat dissipation hole of the housing, improving the heat dissipation effect inside the housing.

[0031] In this embodiment, mounting holes are provided at the four corners of the top of the fixing plate 10, and a rubber pad is arranged at the bottom of the fixing plate 10.

[0032] Local working principle: During the fixing process, screws pass through the mounting holes to directly fix the four corners at the bottom of the fixing plate 10, and the rubber pad at the bottom can ensure close contact with the housing.

[0033] In this embodiment, the positioning mechanism 9 includes a rectangular frame plate 12, a fixing block 13, a sliding rod 14, and a fastening screw 15.

[0035] In this embodiment, anti - detachment blocks are fixed to the ends of the sliding rods 14 far away from the rectangular frame plate 12.

[0036] Local working principle: The use of the anti - detachment blocks can limit the moving length of the sliding rods 14 and prevent the separation between the sliding rods 14 and the fixing blocks 13.
