Resistive load air guide cover

Abstract

The invention relates to an air guide cover, in particular to a resistive load air guide cover. The resistive load air guide cover comprises a housing, a front blocking strip and a rear blocking strip, the housing is divided into an air inlet section, a bending cavity and an air outlet section, and the included angle a of the central lines of the air inlet section and the air outlet section is 105-110 degrees; the air outlet section is internally provided with several air guide sheets, the tail ends of the air guide sheets are bent upward to form opening grooves, and the housings at the two sides of each opening groove are provided with lateral drainage holes; the front blocking strip is located at the top of the air outlet section, and is connected with the air outlet section in a sealing mode, the rear blocking strip is located at the tail end of the air outlet section, and is connected with the air outlet section in a sealing mode, and the bottom of the housing of the left side of the rear blocking section is provided with several bottom drainage holes. Outlet air of the air guide cover tilts upward, even under strong wind and lower pressure, the heat can be dissipated away from a large distance of an air suction opening of a load box, rainwater down from the top of the air outlet section falls into a tail end groove of the air guide sheet through the front blocking strip, and the rainwater splashed from the air guide sheet is drained out through the drainage holes in front of the rear blocking strip. The resistive load air guide cover is reasonable in structural design, high in wind resistant capacity and good in heat dissipation effect.

Description

[0001] Technical field: [0002] The invention relates to a wind deflector, in particular to a resistance load wind deflector. [0003] Background technique: [0004] Resistance load box In order to ensure the normal operation of the load box, it is necessary to quickly discharge the heat of the resistance module to achieve the purpose of heat dissipation. If the air outlet is set on the top of the resistance load box, then when it is used outdoors in rainy weather, the deflector installed at the air outlet can effectively block the rainwater and discharge the heat after diversion. [0005] There are mainly two types of existing shrouds. The first is to discharge air along the horizontal direction of the load box, the air outlet surface is inclined upwards, and the tail end of the deflector has a reverse fold (CN201846556U); the second is to discharge the air downward along the horizontal slope of the load box. Although the two methods mostly or completely block the rainwater...

Problems solved by technology

Although the two methods mostly or completely block the rainwater from entering, they also lead to a large amount of heat that cannot be drifted away when the air volume and pressure of the fan remain unchanged, especially in strong winds or when there are buildings within 3 to 5 meters away from the load box. Dissipates quickly, and is easy to be sucked in from the air inlet again, and the cycle repeats, resulting in poor heat dissipation, which may cause overheating damage to the load resistor module or shorten the service life
