Description

Air inlet of outdoor air cooling equipment

Technical Field

The utility model belongs to the technical field of dustproof equipment, and particularly relates to an air inlet of outdoor air cooling equipment.

Background

With the continuous reduction of the price of the centralized inverter, the container type inverter scheme is gradually eliminated by the market due to higher cost price, higher maintenance rate and the like. In order to improve profit margins of centralized inverters, various inverter manufacturers have introduced outdoor high-power photovoltaic inverters. The high-power centralized outdoor photovoltaic inverter slowly occupies the market leading position due to the advantages of small occupied area, high power density, low cost, convenience in transportation and installation and the like.

Since the high-power centralized outdoor inverter is directly placed in the external environment to work, the protection requirement of the whole shell on dust and water is very high. For dust prevention, the dust prevention requirement can be met only by completely isolating important veneers, components and the like from the main air duct (dust has no influence on electromagnetic elements in the main air duct). But the waterproof performance is difficult to realize, especially the air inlet position of the high-power outdoor air-cooled inverter.

The heat dissipation mode of the main power part of the high-power outdoor air cooling equipment in the current market mainly comprises an upper air inlet mode, a lower air outlet mode, a lower air inlet mode and an upper air outlet mode. For most manufacturers, a heat dissipation mode of upper air inlet and lower air outlet is selected (mainly, the dust at the position higher than the ground is less). Therefore, the waterproof design of the air inlet of the outdoor equipment is very important.

The waterproof air inlet structure of the outdoor high-power air cooling equipment produced by various manufacturers in the market at present has the following two modes.

An elbow is added at the position of an air inlet of the outdoor light high-power air cooling equipment to improve the waterproof performance (consistent with the container scheme), and the air inlet of the elbow faces downwards; a fixed air inlet shutter is added at the position of an air inlet of outdoor high-power air cooling equipment, namely, the outdoor equipment is provided with a top cover independently, and the air inlet is arranged on the top cover.

The above two protection methods have the following problems.

The elbow is added at the air inlet of the outdoor high-power air cooling equipment, so that the depth size of the equipment is increased, the elbow is difficult to assemble and disassemble and difficult to maintain, and the elbow is easy to collide during transportation; the top cover is additionally arranged at the top of the outdoor high-power air cooling equipment, and the fixed air inlet shutter is additionally arranged in the front and at the back or on the left and right of the top cover, so that although the waterproof requirement of the outdoor equipment is met, the shutter part of the air inlet cannot be detached and cannot be maintained.
