Description
Technical field:
the invention relates to a guide sleeve, in particular to a resistance load guide sleeve.
The background technology is as follows:
the resistance load box is in order to ensure that the load box operates normally, and the heat of the resistance module needs to be rapidly discharged to achieve the purpose of heat dissipation. If the air outlet is arranged at the top of the resistance load box, the heat can be discharged after diversion and diversion through the air guide cover arranged at the air outlet when the resistance load box is used in outdoor open air.
The existing air guide sleeve mainly has two types. The first is to discharge air along the horizontal direction of the load box, the air discharge face is inclined upwards, and the tail end of the guide vane is provided with a reverse folded edge (CN 201846556U); the second is to wind downwards along the horizontal inclination of the load box. The two modes can prevent rainwater from entering mostly or completely, but lead to buildings in strong wind weather or 3-5 meters away from the load box especially under the condition that the wind quantity and the wind pressure of the fan are unchanged, a large amount of heat cannot float far and dissipate quickly, and is easily sucked from the air inlet again, and the heat dissipation effect is poor, so that the overheat damage or the shortened service life of the load resistor module can be caused. Therefore, it is necessary to design a resistive load pod.
The invention comprises the following steps:
the invention overcomes and improves the defects of the prior art, and designs the resistance load guide cover with simple structure, strong wind resistance and good heat dissipation effect aiming at the design defects of the prior structure.
The invention adopts the technical scheme that: the resistance load air guide sleeve comprises a shell, a front barrier strip and a rear barrier strip, wherein the shell is divided into an air inlet section, a bent cavity and an air outlet section, and an included angle a of a central line between the air inlet section and the air outlet section is 105-110 degrees; a plurality of guide vanes are arranged in the air outlet section, the tail ends of the guide vanes are bent upwards to form an open slot, and side drain holes are arranged on the shells at the two sides of the open slot; the front barrier strip is positioned at the top of the air outlet section and is in sealing connection with the air outlet section, the rear barrier strip is positioned at the tail end of the air outlet section and is in sealing connection with the air outlet section, and a plurality of bottom drainage holes are formed in the bottom of the shell on the left side of the rear barrier strip.
The intervals among the guide sheets are 80-100 mm.
The length of the plurality of guide vanes is equal, the length of the guide vanes is two thirds of the length of the air outlet section, and the plurality of guide vanes are parallel to each other and parallel to the shell of the air outlet section.
The bottom of the side drain hole is consistent with the bottom of the open slot in height.
The front barrier strip is positioned obliquely above the guide vane, and the section of the front barrier strip is inverted concave; the section of the rear baffle strip is concave, and the rear baffle strip surrounds both sides and the bottom of the air outlet section.
The air outlet end face of the air outlet section is a vertical face, and the air inlet end face of the air inlet section is a horizontal face.
The distance between the guide vane and the tail end of the air outlet section is 80-100 mm, and the left end of the guide vane is level with the left end of the shell.
The invention has the beneficial effects that: simple structure, reasonable in design, the wind-resistant ability is strong, and the radiating effect is good, low cost, safe and reliable easily promotes on a large scale and uses. Under the prerequisite that effectively stops most rainwater entering load case inside, the slant discharges heat upward, and is farther from load case inlet scoop, and the heat is easily dissipated, and the radiating effect is good, satisfies the outdoor rainwater weather of resistance load case well and uses under, has prolonged resistance module's life, simple structure, has saved area when many load cases are arranged side by side.

The specific embodiment is as follows:
referring to the figures, the resistance load air guide sleeve comprises a shell 1, a front barrier strip 2 and a rear barrier strip 3, wherein the shell 1 is divided into an air inlet section 5, a bent cavity 4 and an air outlet section 7, and an included angle a of a central line between the air inlet section 5 and the air outlet section 7 is 105-110 degrees; a plurality of guide vanes 9 are arranged in the air outlet section 7, the tail ends of the guide vanes 9 are bent upwards 10 to form an open slot 11, and side drain holes 8 are arranged on the shell 1 at two sides of the open slot 11; the front barrier strip 2 is positioned at the top of the air outlet section 7 and is in sealing connection with the air outlet section 7, the rear barrier strip 3 is positioned at the tail end of the air outlet section 7 and is in sealing connection with the air outlet section 7, and a plurality of bottom drainage holes 6 are formed in the bottom of the shell 1 at the left side of the rear barrier strip 3; the intervals among the plurality of guide vanes 9 are 80-100 mm, the lengths of the plurality of guide vanes 9 are equal, the lengths of the plurality of guide vanes are two thirds of the lengths of the air outlet section 7, and the plurality of guide vanes 9 are parallel to each other and parallel to the shell 1 of the air outlet section 7; the bottom ends of the side drain holes 8 are in height with the bottom ends of the open grooves 11; the front barrier strip 2 is positioned obliquely above the guide vane 9, and the section of the front barrier strip 2 is inverted concave; the section of the rear barrier strip 3 is concave; the air outlet end face of the air outlet section 7 is a vertical face, and the air inlet end face of the air inlet section 5 is a horizontal face.
The air outlet section 7 of the air guide sleeve inclines 15-20 degrees upwards relative to the horizontal plane of the air inlet section 5, the air outlet surface is a vertical plane, a plurality of equal-length air guide sheets 9 in the air outlet section 7 are parallel to each other and the air outlet section, the upper wall and the lower wall of the air outlet section 7 are parallel, the inclination angle of the air outlet section 7 can ensure that the distance of blowing away after heat is downwards pressed in a high-wind environment is far, and the load box air inlet is not easy to get close to. The tail ends of the guide sheets 9 are curled upwards or folded to form open grooves, and side drainage holes 8 are formed in two sides of the air outlet section opposite to the bottom of the open groove 11 at the tail end of each guide sheet 9, so that most of rainwater flows into the open groove 11 of each guide sheet 9 and is drained from the side drainage holes 8; the interval between the guide vanes 9 and the interval distance between the guide vanes 9 and the air outlet section 7 are both 80-100 mm, the interval enables most of rainwater to fall into the tail end along the guide vanes 9 and be discharged from the drain holes 8 on the two sides, if the interval is too large, the rainproof effect is poor, the air outlet resistance is too small, and meanwhile, the processing is convenient. The front baffle strip 2 is positioned at the top of the air outlet section 7 and above the front slope of the guide vane 9, is inversely concave and is in sealing connection, so that rainwater falling along the top can be ensured to fall into an open groove 11 at the tail end of the guide vane 9 and then be discharged from the drain holes 8 at two sides. The rear baffle strip 3 is positioned at the tail end of the air outlet section 7, surrounds the two sides and the bottom of the air outlet section 7, is in sealing connection, and a row of bottom drainage holes 6 are formed in the shell 1 in front of the bottom of the rear baffle strip 3, so that rainwater splashed from the tail end of the diversion 9 can be effectively prevented from falling into the load box.
