Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and particularly relates to an air-cooled housing for a transformer. Background Art

[0002] The air-cooled housing for a transformer is an auxiliary cooling device designed specifically for oil-immersed transformers. Its main function is to improve the heat dissipation efficiency of the transformer and prevent the transformer from being affected by excessive temperature and thus affecting its normal operation. Such a housing usually includes heat sinks or heat pipes, as well as corresponding fans and control systems.

[0003] The characteristics of the air-cooled housing for a transformer are that heat sinks or heat pipes, these components are welded to the box wall of the transformer to increase the surface area of the transformer in contact with the outside air, thereby improving the heat dissipation efficiency, and then the fan is used to force the air flow to enhance the heat dissipation effect. The fan is usually installed around the heat sink or heat pipe to accelerate the dissipation of the heat of the heat sink.

[0004] Through the housing with such an air-cooled structure, although it can accelerate the dissipation of the heat of the heat sink to a certain extent, its heat dissipation capacity is still limited under extremely high loads or extreme ambient temperatures. And the heat sinks or heat pipes in the air-cooled housing will generate air resistance, resulting in the fan needing to consume more power to maintain the required air flow speed. Moreover, in a dusty or humid environment, when the heat sinks or heat pipes of the air-cooled housing are easily affected by dust, dirt, etc., the heat dissipation efficiency will be reduced.

[0005] Therefore, it is very necessary to invent an air-cooled housing for a transformer to solve the above problems. Content of the Utility Model

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the accompanying drawings.

[0027] The present utility model provides a Figures 1-5 shown air - cooled housing for a transformer, including a housing 1. An air - cooling mechanism 2 is provided on one outer wall of the housing 1. A plurality of connecting pipes 11 are fixedly installed on one outer wall of the housing 1. A plurality of evenly distributed heat - dissipation tubes 6 are fixedly installed on the other side of the housing 1. The housing 1 serves as a protective housing for the transformer, welding heat - dissipation fins or heat - dissipation tubes to increase the surface area in contact with the outside air and improve the heat - dissipation efficiency, which is beneficial to accelerating the dissipation of heat from the heat - dissipation fins to a certain extent;

[0028] The air - cooling mechanism 2 includes:

[0029] The frame 21 is arranged on the outer side of one side of the housing 1, and there is a certain distance between the frame 21 and the outer wall of one side of the housing 1. A partition 23 is arranged on the side of the frame 21 facing the outer wall of the housing 1. The front surface of the frame 21 is sealed by the partition 23 to prevent too much dust from entering the fan 22 from the front of the frame 21;

[0030] A plurality of fans 22 are installed inside the frame 21 and are located on the back of the partition 23. A plurality of air ducts 24 are horizontally and fixedly installed on the front surface of the partition 23 and at the corresponding positions of the plurality of fans 22. The number and positions of the plurality of air ducts 24 correspond to those of the plurality of connecting pipes 11 one by one. Air is supplied by the plurality of fans 22, passes through the plurality of air ducts 24, and is conveyed to the inside of the housing 1 by the connecting pipes 11, thereby adding to the heat flow of the transformer components inside the housing 1.

[0031] Further, in the above technical solution, the front end of the air duct 24 is sleeved on the tail end of the connecting pipe 11. The outer diameter of the air duct 24 is adapted to the outer diameter of the connecting pipe 11. A rubber sleeve 8 is sleeved at the connection between the connecting pipe 11 and the air duct 24. The air duct 24 and the connecting pipe 11 are detachably connected. Since the number of the air ducts 24 and the connecting pipes 11 is large, this connection structure enables the air duct 24 and the connecting pipe 11 to be quickly butted and installed when installing the air cooling mechanism 2, avoiding the use of traditional connection methods such as bolts and nuts, which makes the installation too cumbersome and extremely inconvenient for subsequent disassembly and maintenance.

[0032] Further, in the above technical solution, a groove 3 is formed on the front surface of the frame 21. A filter screen 31 is embedded in the groove 3. The filter screen 31 is located in front of the fan 22. The partition 23 is covered in front of the filter screen 31. The partition 23 is fixedly connected to the frame 21 by bolts. Since the plurality of fans 22 are installed inside the frame 21, in order to enable the fans 22 to work normally and at the same time not affect the heat dissipation of the motors of the fans 22, the back surface of the frame 21 is a hollow structure. Therefore, dust is easily introduced into the position of the back surface of the fan 22. By providing the filter screen 31 on the front surface of the frame 21, it is possible to prevent the fan 22 from transporting dust into the air duct 24 through the air outlet end and then into the inside of the housing 1. Moreover, without affecting the normal operation of the fan 22 and the heat dissipation state of the motor of the fan 22, a filter component can also be installed on the back surface of the frame 21 to improve the dust prevention effect.

[0033] Furthermore, in the above technical solution, a base 7 is provided at the bottom of the housing 1. At both ends of the bottom of the base 7, cushion blocks 4 are installed. Above one end of the frame 21, a support rod 41 is fixedly installed on the cushion block 4. The support rod 41 has an L-shaped structure, and a thread is provided at the front end of the support rod 41. A connecting piece is fixedly installed on the upper end of the housing 1 and on one side of the frame 21. By sleeving the support rod 41 with the support block at the lower end of the frame 21, the bottom of the frame 21 is supported and fixed, the position of the frame 21 is stabilized, and the breakage of the connection between the air duct 24 and the connecting pipe 11 is prevented, so as to avoid affecting the air supply of the fan 22 to the inside of the housing 1.

[0034] Furthermore, in the above technical solution, support blocks 5 are fixedly installed at both ends above and below the frame 21. The support block 5 above the frame 21 is fixedly connected to the connecting piece on one side of the housing 1 by bolts. The support block 5 below the frame 21 is slidably sleeved on the front end of the support rod 41. A nut is installed outside the support block 5 at the front end of the support rod 41. Since the support block 5 below the frame 21 is sleeved on the front end of the support rod 41, the support block 5 below the frame 21 is prevented from falling off the support rod 41 by installing the nut.

[0035] Furthermore, in the above technical solution, both ends of the heat dissipation pipe 6 are connected to the inner wall of the housing 1 in a penetrating manner. A number of evenly distributed heat dissipation holes 61 are formed on the front surface of the heat dissipation pipe 6. The aperture of the heat dissipation holes 61 is not greater than 5 mm. The heat dissipation holes 61 improve the heat dissipation efficiency of the heat dissipation pipe 6. Then, the heat flow caused by the fan 22 inside the housing 1 can be discharged through the heat dissipation holes 61, achieving the purpose of rapid heat dissipation.

[0036] When the air-cooled housing of the transformer provided by the present utility model is in use, its working process is as follows:

[0037] By welding the heat dissipation pipe 6 on the outer wall of one side of the housing 1, the surface area of the transformer housing in contact with the outside air is increased, thereby effectively improving the heat dissipation efficiency. An air-cooling mechanism 2 is provided outside the outer wall of one side of the housing 1, including components such as a frame 21, a fan 22, and an air duct 24, which is used to force air flow and accelerate heat dissipation. The wind generated by the fan 22 is guided by the air duct 24 and enters the inside of the housing 1 through the connecting pipe 11. The rubber sleeve 8 sleeved at the connection between the connecting pipe 11 and the air duct 24 can improve the sealing performance of the connection between the two, and at the same time does not affect the quick disassembly and assembly of the two.

[0038] When the fan 22 conveys cold air into the interior of the housing 1 through the air duct 24 and the connecting pipe 11, conducts heat exchange with the transformer element, and then discharges the hot air through the heat dissipation holes 61 on the heat dissipation pipe 6 to achieve rapid heat dissipation. This air-cooled housing design takes into account the influence of a multi-dust or humid environment, reduces the risk of reduced heat dissipation efficiency through the structural design of the filter screen 31, and allows maintenance and cleaning without affecting the normal operation of the fan 22.

[0039] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
