In addition, ordinary water cooling protection is often directly achieved by introducing tap water for cooling protection. It is not easy to automatically adjust the cooling temperature and achieve active temperature control cooling treatment, which leads to the cooling effect of the device is not good enough. Based on this, we propose a new type of air compressor water channel cooling structure to better meet the operational needs. Utility Model Content
