AI Technical Summary

Technical Problem

In compact scroll air compressors, the heat exchange efficiency between the motor and the water cooling channel is low due to the thin-walled main unit casing, which makes the motor prone to heat accumulation, and existing technologies have limited improvement.

Method used

It adopts a direct-connect design, with water-cooling components and heat-absorbing adjustment components inside the casing. It uses heat-absorbing expansion fluid to absorb and store the heat of the motor, increases the heat exchange area through heat-conducting lifting plates, and uses a spiral cooling cavity to improve the turbulence of the cooling water.

Benefits of technology

It improves the heat transfer efficiency of the motor, avoids heat accumulation, reduces the overall energy consumption, and enhances the heat dissipation effect and operational stability.

Abstract

本发明涉及空气压缩机技术领域,具体地说,涉及一种直连式水冷无油涡旋空压机。其包括机壳,所述压缩腔内部由高到低依次设有驱动电机和涡盘本体;所述机壳内部在涡盘本体高度处外围开设有水冷组件,所述水冷组件内部通入低温水用于导走涡盘本体周围产生的热量,所述机壳内部在驱动电机高度处外围开设有若干个吸热调位组件,位于涡盘本体高度处外围的机壳记为第一散热壳,位于驱动电机高度处外围的机壳记为第二散热壳;吸热膨胀液根据驱动电机发热量实现自适应膨胀与收缩,带动L形的导热升降板上下移动,增加与第一散热壳的贴合换热面积,提升电机热量向水冷组件的传导效率,解决了传统薄壁机壳有效换热面积小、散热能力有限的问题。
