Problems solved by technology
Although the three parts have different degrees of heating problems, the sensors in the sealed spherical shell are the densest, have the most serious heating and have the most obvious impact on product performance. Therefore, it becomes the place where the present invention will focus on cooling and cooling, but is limited by its Due to space constraints, airtightness requirements, and superimposed motion characteristics, the relevant domestic turrets still mainly control the temperature by limiting the working time of the sensor and increasing the air convection velocity in the sealed spherical shell, which has not really solved the external heat dissipation problem of the sensor in essence. , so there is an urgent need for a high-efficiency refrigeration device that can face the airborne stabilized aiming turret
