Description

Technical Field

[0001] The utility model belongs to the technical field of inverters, and in particular relates to an inverter control box which is convenient for heat dissipation. Background Art

[0002] An inverter is a converter that converts DC power into constant frequency and voltage or frequency and voltage regulated AC power. It consists of an inverter bridge, control logic and filter circuit. The inverter is usually placed in an inverter box, which protects it.

[0003] The current inverter box is mainly used to protect the inverter from external influences. The inverter will generate a large amount of heat energy in the process of converting DC power into AC power. The existing inverter box that can dissipate heat cannot adjust the air intake according to the ambient temperature. When the inverter box is placed in a non-constant temperature environment, it is easy to cause the temperature inside the inverter box to be too high or too low, which increases the probability of inverter failure. Utility Model Content

[0004] In view of this, the utility model provides an inverter control box that is easy to dissipate heat, which is used to solve the technical problem that the existing inverter box capable of dissipating heat cannot adjust the air intake according to the ambient temperature, which easily leads to the temperature inside the inverter box being too high or too low.

[0005] The utility model is achieved in this way:

[0006] The utility model provides an inverter control box for heat dissipation, comprising a box body, wherein an air outlet is provided on the top wall of the box body, air inlet holes are provided on the left and right side walls of the box body, fixed ring frames are fixedly installed on the left and right outer side walls of the box body and at positions corresponding to the air inlet holes, dustproof nets are fixedly installed on the ends of the fixed ring frames on both sides away from each other, and fans are fixedly installed in the fixed ring frames;

[0007] Two groups of air volume adjustment components are mirror-imaged in the box body, and the air volume adjustment components include an adjustment frame fixedly installed in the box body, and rotating blades are longitudinally distributed inside the adjustment frame, and a flow channel is formed between any two adjacent rotating blades. A rotating shaft is fixedly installed on the rotating blades, and the rotating shaft is rotatably connected to the inner wall of the adjustment frame, and the ends of the rotating blades are hinged with adjustment rods.

[0008] On the basis of the above technical solution, the inverter control box for heat dissipation of the utility model can also be improved as follows:

[0009] Furthermore, through holes are provided at positions corresponding to the top wall of the box body and the adjusting rod, the adjusting rod is slidably connected in the through holes, and a plurality of adjusting holes are equidistantly provided on the upper portion of the adjusting rod.

[0010] Furthermore, two adjusting columns are fixedly installed on the top wall of the box body, and the two adjusting columns are symmetrically arranged between the through holes. One end of the limiting column is slidably connected to the adjusting column, and the other end of the limiting column is slidably connected to the adjusting hole.

[0011] The beneficial effect of adopting the above further solution is: the adjustment rod is limited by providing the adjustment hole, the adjustment column and the limit column.

[0012] Furthermore, a cover plate is hinged on one end of the fixed ring frame on both sides that is away from each other, a cleaning piece is rotatably provided on the inner end surface of the cover plate, and a rotating mechanism for driving the cleaning piece to rotate is provided on the cover plate.

[0013] Furthermore, the rotating mechanism comprises a handle and a transmission rod, the transmission rod and the cover plate are arranged perpendicular to each other, and the transmission rod is rotatably arranged at the center of the cover plate.

[0014] Furthermore, the handle is fixed to the outer end of the transmission rod, and the inner end of the transmission rod is fixed at the center of the cleaning piece.

[0015] When the cover plate is closed on the air inlet hole, the cleaning piece contacts the dustproof net.

[0016] Compared with the prior art, the utility model provides an inverter control box that is easy to dissipate heat, which has the beneficial effect that by setting an air volume adjustment component, the air intake volume can be adjusted according to the ambient temperature by changing the size of the circulation channel, thereby changing the temperature inside the box.

[0017] The dustproof net is provided to filter dust in the air and prevent dust in the air from entering the inside of the fan, thereby reducing blade wear and dust accumulation inside the fan; the cover plate is provided to protect the dustproof net when the fan is not in use to avoid damage and prevent a large amount of dust from adhering to the surface of the dustproof net due to long-term storage, thereby ensuring the air intake; the cleaning part provided on the cover plate is used to clean the dustproof net when there is a lot of dust on the dustproof net. The dustproof net can be cleaned by rotating the handle to drive the transmission rod to rotate, which is convenient to clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Two sets of air volume adjustment components are mirror-imaged in the box body 1, and the air volume adjustment components include an adjustment frame 2 fixedly installed in the box body 1, and rotating blades 21 are longitudinally distributed inside the adjustment frame 2, and a flow channel 20 is formed between any two adjacent rotating blades 21.

[0032] The rotating shafts 22 are evenly distributed in the adjusting frame 2 and embedded in the adjusting frame 2;

[0033] The air outlet ends of the fans 13 are all facing the air inlet holes 10 , and the fixed ring frame 11 is larger than the air inlet holes 10 .

[0034] Optionally, in the above technical solution, a through hole 31 is opened at the top wall of the box body 1 and at positions corresponding to the adjusting rod 23, the adjusting rod 23 is slidably connected in the through hole 31, and a plurality of adjusting holes 24 are opened at equal intervals on the upper part of the adjusting rod 23.

[0035] Optionally, in the above technical solution, two adjustment columns 32 are fixedly installed on the top wall of the box body 1, and the two adjustment columns 32 are symmetrically arranged between the through holes 31. One end of the limiting column 33 is slidably connected to the adjustment column 32, and the other end of the limiting column 33 is slidably connected to the adjustment hole 24.

[0039] Working principle:

[0040] When working, the fan 13 is started, and the fan 13 draws the outside air into the fixed ring frame 11, and acts on the box body 1 through the circulation channel 20, so that the temperature in the box body 1 is reduced, and the heat is discharged to the outside air through the air outlet 30 on the top wall of the box body 1;

[0041] When the air intake volume needs to be adjusted, the angle of the rotating blade 21 is adjusted to change the size of the circulation channel 20. By moving the adjusting rod 23, the rotating blade 21 is driven by the adjusting rod 23 to rotate, thereby adjusting the angle at which the wind generated by the fan 13 acts on the box body 1.

[0042] When the ambient temperature is low, the adjusting rod 23 is moved downward to reduce the circulation channel 20, thereby reducing the circulation speed of the wind generated by the fan 13; when the ambient temperature is high, the adjusting rod 23 is moved upward to enlarge the circulation channel 20, thereby increasing the circulation speed of the wind generated by the fan 13 to ensure the heat dissipation efficiency in the box 1;

[0043] When the adjusting rod 23 moves up and down, the limiting column 33 is pulled out from the adjusting hole 24 , and when it moves to a suitable position, the limiting column 33 is inserted into the corresponding adjusting hole 24 .
