Abstract
The invention provides a cooling-type infrared core and a manufacturing method therefor, and solves the problems of pool cooling effect, bigger core size and bigger mass in the prior art. The cooling-type infrared core comprises a core housing, a cooling infrared detector, a detector circuit board, a first heat conduction plate, a secondary TEC thermoelectric cooler, a second heat conduction plate, a TEC drive circuit board, an image processing circuit board and an interface converting circuit board, wherein the cooling infrared detector, the detector circuit board, the first heat conduction plate, the secondary TEC thermoelectric cooler, the second heat conduction plate, the TEC drive circuit board, the image processing circuit board and the interface converting circuit board are locatedinside the core housing. One side of the first heat conduction plate is connected with the bottom of the housing of the cooling infrared detector, and the other side is connected with a cold end of the secondary TEC thermoelectric cooler. The hot end of the secondary TEC thermoelectric cooler is connected with one side of the second heat conduction plate, and the second heat conduction plate is connected with the core housing. The TEC drive circuit board, the detector drive circuit board, the image processing circuit board and the interface converting circuit board are sequentially installed from the top to the bottom in a cavity below the second heat conduction board. The secondary TEC thermoelectric cooler is connected with the TEC drive circuit board.
Description
technical field [0001] The invention belongs to cooling infrared imaging technology, and in particular relates to a cooling infrared core and a manufacturing method thereof. Background technique [0002] Infrared cores are developing in the direction of miniaturization, all-weather, long-distance, high-definition, high performance, and low power consumption. Existing cooling infrared cores generally use a first-class TEC thermoelectric cooler, but the cooling effect is poor and cannot Meet the established requirements, or use the Dewar structure to achieve the cooling effect, but this structure is large in size and heavy in weight, which is not easy to carry and transport. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies in the prior art, such as poor refrigeration effect, large core volume and heavy weight, and provide a refrigeration type infrared core and a manufacturing method thereof. [0004] To achieve the above o...
