Description

Technical Field

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

[0002] A rectifier cabinet is a device used to convert alternating current into direct current. It can be used in the fields of DC motor speed regulation, generator excitation regulation, electrolysis and electroplating. Since most existing rectifier cabinets are high-power, the current passing through the components in the cabinet is large, so the rectifier components heat up seriously. In order to make the rectifier components work normally, it is necessary to cool the components. Current rectifier cabinets are generally equipped with a heat dissipation structure, which can quickly discharge the heat generated by the electronic components inside the rectifier cabinet.

[0003] For example, the patent with publication number CN220042770U specifically discloses a rectifier cabinet that is easy to dissipate heat and prevent dust. By setting a filtering structure in the filtering area of ​​the peripheral wall, the filter element filters the dust to prevent dust from entering the cabinet and causing short circuits in components, thereby extending the service life of the cabinet.

[0004] In the above patent, the device extracts the hot air inside the rectifier cabinet by setting up an exhaust fan to achieve the purpose of heat dissipation of the rectifier cabinet, but the heat dissipation structure can only keep the temperature inside the rectifier cabinet at room temperature. When the weather is hot, the temperature in the air also increases. At this time, the exhaust fan may not be able to effectively discharge the hot air in a high temperature environment. Especially when the external air temperature is close to or higher than the internal temperature of the rectifier cabinet, the heat dissipation efficiency is greatly reduced. Therefore, it is necessary to provide a rectifier cabinet heat dissipation structure with a refrigeration device to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a heat dissipation structure for a rectifier cabinet to achieve the effect of making the heat dissipation efficiency of the rectifier cabinet higher.

[0007] The technical solution adopted by the present application to solve its technical problems is: a rectifier cabinet heat dissipation structure, including a main cabinet; a sub-cabinet, which is detachably arranged on the top of the main cabinet, and a receiving cavity is arranged in the sub-cabinet, and the bottom of the receiving cavity is connected with the interior of the main cabinet; a heat dissipation component, which is arranged inside the sub-cabinet, and the heat dissipation component includes a connecting block, which is arranged in the receiving cavity, and the connecting block is provided with a through hole from the top to the bottom; a clamping block, which is slidably installed on the top of the connecting block, and a fan is fixedly installed at the center of the clamping block; an air hole, which is arranged on the top of the sub-cabinet; a mounting frame, which is arranged on one side of the connecting block, and a water cooling pipe is arranged on the mounting frame.

[0008] Furthermore, an installation cavity connected to the main cabinet is provided on one side of the main cabinet, and an auxiliary fan is provided in the installation cavity.

[0009] Furthermore, a notch is provided on one side of the connecting block, a pull-out plate is slidably installed in the notch, and a penetrating installation groove is provided at the center of the pull-out plate, and the installation groove is used to install the filter.

[0010] Furthermore, the water cooling pipe has a water inlet pipe and a water outlet pipe, and both the water inlet pipe and the water outlet pipe run through the auxiliary cabinet.

[0011] Furthermore, the wind directions of the fan and the auxiliary fan can be adjusted in reverse.

[0012] The beneficial effect of the present application is that the heat dissipation structure of the rectifier cabinet provided by the present application enables the staff to switch freely according to the external temperature conditions by setting water cooling pipes, fans and auxiliary fans, so that the main cabinet can save energy under suitable temperature conditions and effectively control and reduce the temperature inside the main cabinet at high temperatures, so that the main cabinet can maintain the best working state under different climatic conditions, thereby improving adaptability and stability.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] like Figure 1-Figure 3 As shown, the present application provides a rectifier cabinet heat dissipation structure, including a main cabinet 1, which is arranged in a machine room and is used to rectify alternating current and convert it into direct current. At the same time, a sub-cabinet 2 is arranged on the top of the main cabinet 1, and the sub-cabinet 2 is used to timely dissipate heat for the equipment in the main cabinet 1 to prevent it from being damaged due to excessive temperature;

[0024] The sub-cabinet 2 can be detachably mounted on the top of the main cabinet 1, so that the maintenance of the sub-cabinet 2 is more convenient, and the bottom of the sub-cabinet 2 is connected to the inside of the main cabinet 1, and a receiving cavity is provided in the sub-cabinet 2, and a heat dissipation component 3 is provided inside the receiving cavity. The heat dissipation component 3 includes a connecting block 31, and the connecting block 31 is fixedly mounted on the bottom of the receiving cavity. The connecting block 31 is provided with a through hole from the top to the bottom, and two groups of card blocks 32 are slidably mounted on the top of the connecting block 31, and a fan 33 is fixedly mounted at the center of the card block 32. When the fan 33 needs to be cleaned or replaced, the card block 32 can be controlled to slide on the top of the connecting block 31, so that the card block 32 is quickly moved to the outside of the sub-cabinet 2, and the fan 33 in the card block 32 can be replaced or cleaned at this time;

[0025] Compared with traditional fixed fans, this replacement method enables maintenance personnel to clean or replace the fan 33 more quickly, reducing downtime during maintenance and improving equipment availability and stability. This installation method also reduces interference with other equipment or systems and is suitable for installation in a relatively limited space such as the sub-cabinet 2.

[0026] At the same time, a plurality of air holes 36 are provided on the top of the auxiliary cabinet 2, and the fan 33 is used to extract the hot air inside the main cabinet 1, so that the inside of the main cabinet 1 maintains a suitable temperature;

[0027] At the same time, a slot 34 is provided on one side of the connecting block 31, and a pull-out plate 35 is slidably installed in the slot 34. A penetrating installation slot is provided at the center of the pull-out plate 35, and the installation slot is used to install a filter screen, which is used to filter the air in the main cabinet 1, thereby preventing dust, fine particles or other impurities from entering the fan 33, reducing pollution and dust accumulation inside the equipment, and helping to keep the equipment clean and operating efficiency. In addition, since the filter screen is installed in the pull-out plate 35, the pull-out plate 35 can be easily taken out of the slot 34, so that the staff can quickly clean or replace the filter screen, thereby preventing the air flow from being weakened or the fan 33 from being overloaded due to excessive clogging of the filter screen, thereby extending the life of the equipment inside the rectifier cabinet;

[0028] At the same time, an installation cavity 4 connected to the main cabinet 1 is provided on one side of the main cabinet 1, and an auxiliary fan 41 is provided in the installation cavity 4. The auxiliary fan 41 is used to introduce external air into the main cabinet 1, thereby promoting air circulation and ventilation, effectively increasing the air circulation volume, and then stabilizing the working temperature of the equipment and preventing overheating.

[0029] In order to reduce the internal temperature of the main cabinet 1 in hot weather, improvements are made in the auxiliary cabinet 2, specifically:

[0030] like Figure 2-Figure 3 As shown, a mounting frame 5 is provided at the top of the fan 33 in the sub-cabinet 2, and a water cooling pipe 51 is provided on the mounting frame 5. The water cooling pipe 51 is used to store the cooling medium, and the water cooling pipe 51 has a water inlet pipe 52 and a water outlet pipe 53, and the water inlet pipe 52 and the water outlet pipe 53 both penetrate the sub-cabinet 2, wherein the water inlet pipe 52 is connected to an external liquid storage device, and is used to introduce the cooling medium into the water cooling pipe 51, and the water outlet pipe 53 is used to discharge the coolant in the water cooling pipe 51, and make it cool down again after being cooled by the external cooling system, and then be recycled again;

[0031] When the outside temperature is relatively suitable, the water cooling pipe 51 is closed, and the outside air flows into the main cabinet 1 through the auxiliary fan 41, and is discharged from the fan 33 after circulating in the main cabinet 1, thereby achieving natural ventilation and temperature regulation;

[0032] When the outside temperature is relatively hot, the water cooling pipe 51 is first opened to allow the coolant to circulate in the water cooling pipe 51, and then the output wind directions of the fan 33 and the auxiliary fan 41 are reversed, so that the cooled air enters the main cabinet 1 from the fan 33, and is discharged from the auxiliary fan 41 after circulating in the main cabinet 1, so as to enhance the cooling effect.

[0033] To sum up, the device provides a water cooling pipe 51, a fan 33 and an auxiliary fan 41, so that the staff can switch freely according to the external temperature conditions, so that the main cabinet 1 can save energy under suitable temperature conditions, and can effectively control and reduce the temperature inside the main cabinet 1 at high temperatures, so that the main cabinet 1 can maintain the best working state under different climatic conditions, thereby improving adaptability and stability.

[0034] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
