Technical Field

[0001] The utility model relates to the technical field of rectifier cabinets, in particular to a rectifier cabinet heat dissipation structure. Background Art

[0002] Rectifier cabinet is a kind of device based on the principle of diode and thyristor rectification. It is combined into a whole through a certain connection method by integrating thyristors, heat sinks, fuses, AC and DC busbars, and insulating plates. Its function is to convert AC into DC. It can be used in the fields of DC motor speed regulation, generator excitation regulation, electrolysis and electroplating. Since most of the existing rectifier cabinets are high-power, the current passing through the components in the cabinet is relatively large. In this way, the heating of the components caused by the loss is relatively serious. In order to make the components work normally, it is necessary to dissipate heat and cool the components inside the rectifier cabinet.

[0003] The existing rectifier cabinet heat dissipation structure generally includes an induced draft fan, a vent and a filter plate. When in use, the hot air inside the rectifier cabinet is sucked out by the induced draft fan, and at the same time, the outside air will enter the rectifier cabinet through the vent, and the filter plate can prevent external impurities from entering the rectifier cabinet.

[0004] The disadvantages of the existing rectifier cabinet heat dissipation structure are that: since the filter plate can only prevent larger impurities from entering the rectifier cabinet, some smaller dust and impurities can easily pass through the mesh holes of the filter plate and enter the rectifier cabinet, resulting in poor filtering effect, and fine impurities and dust can easily damage the electrical components in the rectifier cabinet. Therefore, it is necessary to propose a rectifier cabinet heat dissipation structure to solve the above-mentioned problems. Utility Model Content

[0007] The right sides of the two positioning rods are both provided with a tensioning mechanism.

[0008] In order to facilitate tightening the two positioning rods to the left, as a preferred rectifier cabinet heat dissipation structure of the utility model, the two tightening mechanisms include screws respectively fixedly connected to the left ends of the two positioning rods, and the outer walls of the two screws are threadedly connected with tightening blocks that are squeezed with the left ends of the two connecting blocks.

[0009] In order to facilitate improving the positioning effect when installing the installation frame and the filter screen, and to allow the two screws to smoothly pass through the inside of the two positioning holes, as a preferred rectifier cabinet heat dissipation structure of the utility model, the two positioning rods are respectively matched with the inside of the two positioning holes, and the maximum diameters of the two screws are respectively smaller than the diameters of the two positioning rods.

[0010] In order to facilitate the installation of the induced draft fan, as a preferred heat dissipation structure of a rectifier cabinet of the utility model, a support plate is fixedly connected to the left side of the rectifier cabinet body, and the induced draft fan is fixedly connected to the upper side of the support plate.

[0011] In order to achieve an anti-skid effect when the two tightening blocks are rotated, as a preferred heat dissipation structure of a rectifier cabinet of the utility model, the outer walls of the two tightening blocks are provided with anti-skid patterns.

[0012] In order to facilitate supporting the device, as a preferred rectifier cabinet heat dissipation structure of the utility model, the left and right sides of the rectifier cabinet body are fixedly connected with horizontal plates located below the support plate, and the lower ends of the two horizontal plates are fixedly connected with support frames.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The filter screen can prevent larger impurities in the outside air from entering the interior of the rectifier cabinet body, while the filter cotton can prevent smaller impurities and dust in the air from entering the interior of the rectifier cabinet body, thereby improving the filtering effect to prevent damage to the electrical components in the rectifier cabinet body;

[0015] When the filter cotton needs to be installed, cut it and put it into the frame, then insert the two positioning rods into the two positioning holes. At this time, the installation frame is in contact with the filter cotton, and then the two positioning rods are tightened to the left by two tensioning mechanisms respectively, and the installation frame squeezes and fixes the filter cotton. When the filter cotton needs to be taken out, just follow the reverse steps to achieve the effect of disassembling, cleaning or replacing the filter cotton. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the filter screen 8 can prevent larger impurities in the outside air from entering the inside of the rectifier cabinet body 1, and the filter cotton 6 can prevent smaller impurities and dust in the air from entering the inside of the rectifier cabinet body 1, thereby achieving the effect of improving the filtering effect to prevent damage to the electrical components in the rectifier cabinet body 1;

[0037] When the filter cotton 6 needs to be installed, the filter cotton 6 needs to be cut into a shape matching the interior of the frame 4, and then it is placed in the interior of the frame 4, and then the two positioning rods 17 are respectively inserted into the interior of the two positioning holes 11. At this time, the left side of the installation frame 7 is located in the interior of the frame 4 and contacts with the filter cotton 6. Then the two tightening blocks 13 are screwed into the outer walls of the two screws 12, and then they are squeezed with the two connecting blocks 10, so as to facilitate the two positioning rods 17 to be tightened to the left.
