本发明的工作原理和有益效果为：
使用过程中电气控制柜100内产生的热量会传导到吸热板200上，吸热板200在将热量传导到导热片201上，导热片201的热量会传导到导热管202上，过程中可以开启水泵205，水泵205能够将水箱204中的水抽出并通过导热管202流通，水在流过导热管202的过程中会带走导热管202的热量，实现热交换，最终水会在通过导热管202的另外一端回到水箱204内，实现循环使用，水箱204内水会在持续的换热过程中逐渐升温，水的温度会传导到导温板207上，过程中可以开启半导体制冷片208，利用半导体制冷片208的特性在开启时 能够使其一面制冷一面制热，半导体制冷片208的制冷面与导温板207贴合，从而为导温板207进行降温，进而对与导温板207接触的水进行降温，而半导体制冷片208的制热面则与导热铜板209贴合，使其热量传导到散热管210与散热鳍片211上，配合开启风机314，风机314输出端会朝导风管305上的连通孔320内吹风，使得气流通过连通孔320上的第三出风口308输送到分流管309中，之后在通过分流管309进入导风罩310，从导风罩310吹出，过程中气流会吹过导风罩310内的散热鳍片211与散热管210，从而带走散热鳍片211与散热管210的热量，为半导体制冷片208的制热面进行散热，提升半导体制冷片208制冷面的制冷效果，另一方面，风机314吹出的部分气流会通过第二出风口307进入其中一个伸缩波纹管303，最终从第二出风槽312中吹出到通风口101内，使得空气能够快速从两个通风口101中流通，对电气控制柜100内进行换热。
换热过程中开启电机213能够使其输出端带动第一皮带轮214转动，第一皮带轮214转动时会通过与皮带215的配合带动两个第二皮带轮216进行转动，转动的第二皮带轮216则会带动联动轴217转动，而联动轴217则会带动叶片218在水箱204内搅动，使水箱204内水能够流动，使水能够与导温板207充分接触，提升对水的降温效果，且持续转动的联动轴217会带动第一锥形齿轮318转动，第一锥形齿轮318转动时会通过与第二锥形齿轮319的啮合而带动正反牙丝杆301转动，转动的正反牙丝杆301会在两个连接座300上转动，持续转动的正反牙丝杆301会通过与螺纹孔317的配合带动安装座316往复水平滑动，从而使得往复滑动的安装座316带动出风盒302滑动，出风盒302滑动时会拉伸伸缩波纹管303并带动第二出风槽312滑动，第二出风槽312往复滑动的过程中能够使空气均匀的吹入通风口101内，提升换热效果。
在冬季环境温度较低的情况下使用时可以单独开启风机314与电热管411，气流在经过电热管411时会被加热，最终通过第二出风槽312吹到电气控制柜100内，对电气控制柜100内的电气元件进行加热，冬季使用时金属防护棚403能够用来挡雪，若金属防护棚403上积雪较多可以开启调节气缸412，调节气缸412的输出端会推动联动齿条413移动，移动的联动齿条413则会通过与调节齿环414的啮合而带动调节齿环414转动，转动的调节齿环414会在带动导风管305在导风盒304内转动，导风管305转动的过程中会带动第三出风口308与第二出风口307移动，第三出风口308与第二出风口307分别断开与伸缩波纹管303、分流管309的连通，同时导风管305会带动第一出风口306与靠近第一出风槽311一侧的伸缩波纹管303连通，此时第一出风口306与伸缩波纹管303、第一出风槽311处于连通状态，而第二出风槽312则处于关闭状态，然后在开启风机314与电热管411，使得热气流通过第一出风槽311吹到金属防护棚403底侧，为金属防护棚403进行加热，加速积雪的融化，过程中配合开启电机213能够使出风盒302往复移动，使热气被均匀吹到金属防护棚403上，出风盒302往复移动的同时可以开启挤压气缸406，挤压气缸406的输出端会带动固定架407移动，使得移动的固定架407带动滚轮408与连接板404接触，在出风盒302往复移动的过程中滚轮408会跟随移动，往复移动的滚轮408会挤压在弧形抵块405上，弧形抵块405受到挤压时会带动连接板404与对应的活动撑杆402移动，使得活动撑杆402通过与金属防护棚403的配合带动另外一侧的活动撑杆402移动，活动撑杆402滑动的过程中会通过导向滑孔409在导向杆401上滑动，进而限制了活动撑杆402的移动方向，两侧的活动撑杆402在移动的过程中会拉伸或者挤压对应的弹簧410，当移动的滚轮408从弧形抵块405上脱离时，弧形抵块405不在受到挤压，处于拉伸或者压缩状态的弹簧410会在拉动对应的活动撑杆402移动复位，进而在滚轮408的往复挤压下，能够使金属防护棚403实现往复晃动的效果，以便将金属防护棚403上的积雪晃掉，进一步提升除雪效果。
