Description

一种防尘车载逆变器 技术领域
本实用新型属于充电设备技术领域，尤其涉及一种防尘车载逆变器。
背景技术
逆变器是把直流电能(电池、蓄电瓶)转变成定频定压或调频调压交流电(一般为220V,50Hz正弦波)的转换器。
随着社会的发展和人民生活水平的提高，人们使用汽车外出工作、旅游的情况正逐渐增多，通过逆变器连接蓄电池可以在车上使用各种电器及各种工具工作，带来了极大的便利。逆变器在使用过程中会产生热量，为了不影响逆变器的正常使用，现有的逆变器一般都是使用散热风扇对逆变器进行散热降温，在散热风扇工作的时候，会将外部的灰尘等杂质带入逆变器内部，所以现有的逆变器都会安装有防尘组件。
现有车载逆变器的防尘组件一般由防尘板以及粘贴在防尘板上的防尘网组成，这种防尘组件由于防尘板和防尘网不可拆分，当车载逆变器使用了一段时间，防尘组件上积累了较多灰尘杂质需要清洗时，需要将整个防尘组件拆卸下来，将防尘板和防尘网一起清洗，十分麻烦，且现有的防尘板都是塑料材质的，频繁清洗很容易将防尘板刮花甚至损坏，降低了防尘组件的使用寿命，进而影响了车载逆变器的正常使用。
因此，需提供一种防尘车载逆变器，以解决现有技术的不足。
