Description

Technical Field

[0001] The utility model relates to the technical field of resistors, in particular to an air-cooled resistor. Background Art

[0002] A resistor box is a variable resistor that can adjust the resistance value. A large number of resistors are placed in the resistor box for resistance adjustment. It is widely used in energy consumption control systems powered by variable frequency motors. It generally includes a box body and a resistor component arranged inside the box body. The function of the box body is to protect the resistor from external influences during use, and the modular resistor is to divide the resistor component into multiple independent modules.

[0003] However, it still has the following disadvantages in actual use:

[0004] A wind-cooled module resistor with the publication number CN219457252U is retrieved, comprising a resistor body, a box door, and a resistor row. An air outlet baffle is fixedly installed on the top outer wall of the resistor body, and an air inlet filter is arranged on the bottom outer walls of both sides of the resistor body. The utility model drives the air inlet fan to rotate through the air inlet motor, so that the external air enters the inner cavity at the bottom of the resistor body through the air inlet filter, and blows into the inner cavity of the resistor body through the air inlet plate to cool the resistor row. At the same time, the hot air emitted from the inside drives the fan blades to rotate through the air outlet motor, and blows out of the air outlet net, so that air circulation is formed in the inner cavity of the resistor body, which solves the problem that the existing module resistor has poor heat dissipation effect and flying insects easily enter the inside of the resistor through the heat dissipation holes, causing damage to the resistor row inside the resistor, and achieves the effect of rapid heat dissipation and cooling, and prevents dust and mosquitoes from entering, thereby improving the cleanliness of the working environment of the resistor row.

[0005] However, the resistor banks of the above device are arranged and installed, and the hot air is exchanged only through one outlet, so the cooling effect on the resistor banks is poor, and all the resistor banks cannot be evenly dissipated and cooled, which affects the normal use of the resistor banks. Utility Model Content

[0006] The purpose of the utility model is to provide an air-cooled resistor to solve the problem raised in the above-mentioned background technology that hot air is exchanged only through one outlet, the cooling effect on the resistor array is poor, all resistor arrays cannot be evenly dissipated and cooled, and the normal use of the resistor array is affected.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is an air-cooled resistor, comprising:

[0009] A main body structure, the main body structure comprising a frame;

[0010] A cooling mechanism, the cooling mechanism comprising a mounting frame fixedly connected to the top of the frame;

[0011] A uniform mechanism, the uniform mechanism includes an output frame fixedly connected to the inner wall of the top of the frame, the outer wall of the output frame is fixedly connected to a first connecting tube, the first connecting tube is fixedly connected to the inner wall of the frame, the first connecting tube is fixedly connected to a second connecting tube symmetrically on the left and right, and the outer walls of the first connecting tube and the second connecting tube are equidistantly provided with output holes.

[0012] Furthermore, first heat dissipation holes are equidistantly provided on the outer walls of both sides of the frame, mounting frames are symmetrically fixedly connected to the inner wall of the frame, a resistor row is fixedly connected between the two mounting frames, and a first movable door is hingedly connected to the outer wall of the frame;

[0013] Furthermore, a fixing plate is fixedly connected to the inner wall of the installation frame, a motor is fixedly connected to the inner wall of the fixing plate, a fan is fixedly connected to the output end of the motor, and a second movable door is hingedly connected to the outer wall of the installation frame;

[0014] Furthermore, the installation frame is fixedly connected with an oil inlet pipe, the end of the oil inlet pipe is close to the connection between the motor and the fan, and the output frame corresponds to the output end of the installation frame;

[0015] Furthermore, it also includes an anti-blocking mechanism, which includes a slide groove provided on the outer wall of the installation frame, a spring is fixedly connected to the inner wall of one end of the slide groove, and a sliding block is fixedly connected to the other end of the spring;

[0016] Furthermore, the sliding block is slidably connected to the inner wall of the sliding groove, the outer wall of the sliding block is fixedly connected to a connecting shaft, the outer wall of the connecting shaft is symmetrically fixedly connected to a cleaning rack, and the cleaning rack corresponds to the second heat dissipation hole;

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. The utility model turns on the motor to drive the fan to rotate. The fan exchanges the heated air around the upper resistor row with the outside air through the output frame, thereby cooling and protecting the upper resistor row. The output frame extends to the resistor row position far away from the output frame through the first connecting tube and the second connecting tube, and exchanges the air around other resistor rows with the outside air through the output hole, thereby achieving uniform cooling of the resistor rows at various positions, avoiding the situation where the temperature of the resistor rows at other positions is not significantly cooled, affecting the use of the resistor rows.

[0019] 2. Based on beneficial effect 1, manually pull the sliding block, slide the sliding block to the end of the slide slot and stretch the spring. After releasing the sliding block, the spring rebounds and drives the sliding block to slide along the slide slot. The linear motion of the sliding block drives the connecting shaft to move linearly along the slide slot. The linear motion of the connecting shaft drives the cleaning rack to move. The cleaning rack is inserted into the second heat dissipation hole for cleaning to prevent the second heat dissipation hole from being blocked and affecting the cooling effect of the resistor row.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
