一种具有风冷功能的交流emi滤波器

Exchange EMI wave filter with forced air cooling function

Abstract

The utility model provides an exchange EMI wave filter with forced air cooling function. This wave filter includes sealed shell, is fixed in filtering body and air cooling pipeline in the shell, be equipped with first pipeline inserted hole and second pipeline inserted hole on shell one side, air cooling pipeline one end links to each other with air -cooled control system air outlet, and the other end links to each other with air -cooled control system return air inlet after passing first pipeline inserted hole and second pipeline inserted hole. The utility model discloses a three -phase AC EMI wave filter has air -cooled function, and air cooling pipeline adopts the good metal material of heat transfer performance, can in time conduct away the heat of reactor, electric capacity to reduce the whole temperature rise of wave filter, have reliable long -term serviceability, prolonged the bulk life time of wave filter simultaneously.
本实用新型提供了一种具有风冷功能的交流EMI滤波器。该滤波器包括密封的外壳、固定于外壳内的滤波本体和风冷管道,所述外壳一侧上设有第一管道插入口和第二管道插入口,所述风冷管道一端与风冷控制系统出风口相连,另一端穿过第一管道插入口和第二管道插入口后与风冷控制系统回风口相连。本实用新型的三相交流EMI滤波器具有风冷功能,风冷管道采用传热性能良好的金属材料,能将电抗器、电容的热量及时传导出去,从而降低滤波器的整体温升,具有可靠的长期运行能力,同时延长了滤波器的整体寿命。
