Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, in an embodiment of the present invention, an air cooling device for heat dissipation of a wind power converter cabinet includes: rack body 1, windshield 2 and fan 3, its characterized in that: 1 both sides of rack body are equipped with air intake and air exit respectively, 2 fixed mounting of windshield are at the air intake, 3 fixed mounting of fan are at the air exit, be equipped with outside outstanding cavity 21 in the middle of the windshield 2, be equipped with a plurality of wind gaps 211 on the cavity 21, wind gap 211 is from last down evenly distributed, and the wind gap 211 outside is equipped with dust cover 22, dust cover 22 covers in the wind gap 211 outside, shelters from wind gap 211, and dust cover 22 left side, right side and upside and cavity 21 fixed connection are as an organic whole, and the uncovered setting in bottom, simultaneously wind gap 211 is equipped with dust guard 212.
The area of wind gap 211 is less than the area of dust cover 22, dust cover 22 and dust guard 212 can play dustproof effect, prevent that the dust from getting into cabinet body 1 inside, simultaneously because the area of dust guard 212 is less than the area of wind gap 211, therefore dust cover 22 bottom is uncovered to and the space between dust guard 212 and the wind gap 211 can form the ventiduct and be used for the heat dissipation.
