Refrigeration infrared detector

The refrigeration infrared detector comprises a Dewar shell, a cold shield assembly, an infrared detection chip and a refrigerator, the Dewar shell comprises a Dewar window and a window frame, the Dewar window and the window frame are made of the same material and are integrally formed, the cold shield assembly comprises a heat conduction substrate, and the infrared detection chip is arranged on the heat conduction substrate. The infrared detection chip is fixed on the heat conduction substrate of the cold shield assembly, the refrigerator is fixed on the heat conduction substrate of the cold shield assembly, compared with a traditional Dewar shell made of germanium and metal, the manufacturing complexity is reduced, the high consistency of products is improved, and therefore the high reliability of batch products is improved. 本申请实施例公开了一种制冷红外探测器，包括杜瓦外壳、冷屏组件、红外探测芯片和制冷器，所述杜瓦外壳部件包括杜瓦窗口和窗框，所述杜瓦窗口与所述窗框使用相同材料且一体成型，所述冷屏组件包括导热基板，所述红外探测芯片固定于所述冷屏组件的导热基板上，所述制冷器固定于所述冷屏组件的导热基板上，相比传统的锗加金属的杜瓦外壳相比，降低了制作复杂度和提高了产品的高一致性，从而提高了批量
