The utility model relates to a new type of radar cooling system, the air outlet end is connected with the inner ring of the bearing of the air conditioning, the bearing outer ring is connected with the cover plate; the air outlet is placed in the center of the bearing hole; the receiver antenna arm cavity receiver is the same core hole of the radiating surface of bearing. Therefore, when the air conditioning works, the air conditioning produces air flow through the bearing center hole to the receiver. The inner ring of the bearing and the air conditioner can be rotated relative to the outer ring of the bearing. The bottom of the air conditioner is equipped with counterweights, the counterweight is installed at the bottom of the air conditioner, so that the center of gravity of the air conditioner deviates from the center of the bearing rotation, and the torque of the center of gravity of the air conditioner to the center of the bearing rotation is greater than the friction torque between the inner and outer parts of the air conditioner. This method can ensure that the antenna arm is moving in the range of 0 to 90 degrees, and the air conditioning can still be in the original working state. The guard plate A is installed on the cover plate, the guard plate B is installed on the outer circle of the air conditioner, the guard plate A and the guard plate B form the labyrinth seal, prevents the dust and the water to enter the bearing and the support arm cavity.

一种新型的雷达冷却系统
本技术涉及一种雷达冷却系统,属于机械电子结构领域。
技术介绍
随着技术不断进步及成本不断降低,全固态发射机技术逐渐应用到天气雷达,进而为研制全固态天气雷达提供技术支撑。全固态发射机具有体积小重量轻优点,这就为发射机置于天线座支臂上提供了技术基础。发射机置于天线座支臂不但可以减少信号损耗,还可避免使用波导旋转关节,进而可以提高雷达性能,同时降低成本。因发射机置于天线座支臂,所以为取得最佳性能需将接收机同样置于天线座支臂,这就为接收机的冷却带来了困难。因为天线座支臂既在0°至90°的范围内进行俯仰(沿平行于地面轴的转动)运动,又进行360°方位(沿垂直于地面的轴旋转)旋转运动。而普通压缩机的空调虽然能随方位进行360°旋转运动,但只能在-15°至15°范围内摆动工作。而热电空调虽然可以随方位360°旋转,又可在0度至90度范围内进行俯仰运动,但在实际使用中制冷效果达不到要求,且可靠性较低,故障率高。这就需要一种结构解决压缩机空调不能进行俯仰运动工作的问题,还可避免使用热电空调制冷效果不足,可靠性低的问题。
