Abstract
The invention relates to a ventilation heat abstractor of an inverter, comprising a fan and a fan cover. The fan is arranged at the bottom in a box body, the fan cover is arranged on an air outlet ofthe fan and is fixed on the outer side of the box body, the bottom of the fan cover is provided with a plurality of concentric ring-shaped sink grooves, the side walls of the ring-shaped sink groovesare provided with a plurality of ventilation holes, and sponge blocks are attached to the outer side surface of the box body in the fan cover. The ventilation heat abstractor of the inverter can not only resist water and dust, but also can better ensure the ventilation and the heat abstraction of the inverter.
Description
Technical field
The present invention relates to the ventilation heat abstractor of photovoltaic/wind generator, be specifically related to the ventilation heat abstractor of the advancing of a kind of inverter/air outlet waterproof and dustproof.
Background technology
Photovoltaic/wind power grid-connected generating technology is the important component part of renewable energy technologies development, has also obtained tremendous development in recent years, and the part technology has realized commercialization, but also comes with some shortcomings.At present, in order to solve outdoor inverter heat dissipation problem, some adopts and on the casing of inverter fan is installed is that air cooling way dispels the heat; , Wai Mian water and dust are easy to enter in the casing by the fan fresh air inlet like this, thereby influence the serviceability of complete machine, even cause the damage of device.Therefore, designing a kind of excellent waterproof dustproof aeration structure is the problem that inverter producer must solve.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, designed and developed out a kind of can water proof and dust proof again can fine ventilation structure.
The present invention is achieved by the following technical solutions:
A kind of ventilation heat abstractor of inverter, comprise the fan that is installed in the casing inner bottom part, be installed in the fan guard that fan outlet is fixed on the casing outside, described fan guard bottom has the circular deep gouge of several concentrics, and the sidewall of annulus deep gouge has a plurality of ventilation holes.
A kind of ventilation heat abstractor of inverter is attached with sponge block on the inherent casing lateral surface of described fan guard.
Fan guard of the present invention top has the circular deep gouge of several concentrics, and its sidewall has several ventilation holes, can't see ventilation hole from the front of fan guard.From formed in mould angle, ventilation hole is worn technology by bumping of mould and is realized, can avoid rainwater directly to enter fan guard by bumping the ventilation hole of wearing technological forming; Fan is covered with certain thickness, guarantees that several ventilation holes at fan guard top and fan have certain distance, even if there is a spot of water to enter in the fan guard, plays buffer action by foam-rubber cushion, also can not arrive the position of blower fan; Under the effect of gravity, these a spot of water all can ooze out by several ventilation holes of fan guard, and play the effect of waterproof and dustproof, ventilation.
