Description

Technical Field

[0001] This utility model belongs to the field of transformer rectifier technology, and more specifically, it relates to a transformer rectifier device with high-efficiency heat dissipation. Background Technology

[0002] A rectifier transformer is a power transformer used in rectifier equipment. The characteristic of rectifier equipment is that the primary side receives AC input, while the secondary side outputs DC after passing through rectifier elements. Converter technology encompasses three operating modes: rectification, inversion, and frequency conversion, with rectification being the most widely used.

[0003] Application number CN202420092987.3 discloses an integrated transformer rectifier device. An air intake component is located at the lower part of the housing, and an exhaust component is located at the upper part of the housing. Transformer rectifier components are located in the middle of the housing. A filter component with a replaceable filter screen is located on one side of the housing, and the filter component covers the air inlet of the air intake component. The advantages of this invention are: This integrated transformer rectifier device draws in air through the air intake component and blows it upwards, carrying away heat from the components before being drawn out of the housing by the exhaust component. Before being drawn in by the air intake component, the air passes through the filter component to remove most of the dust, ensuring that the inside of the device is not contaminated by dust. The structure of blowing air from below and drawing air from above maximizes the removal of hot air, forming a bottom-to-top airflow without dead zones, ensuring efficient and stable heat dissipation.

[0004] Based on the above patent searches and understanding of the application of existing transformer rectifier devices:

[0005] Although some devices use a bottom-up airflow cooling method, the cooling position is relatively singular, mainly relying on the airflow formed by bottom air intake and top exhaust, which is difficult to fully cover all areas of the rectifier transformer, especially for parts such as the sides of the transformer, where the cooling effect is poor.

[0006] On the other hand, the installation and removal of some heat dissipation components are not convenient enough. When it is necessary to maintain or replace the heat dissipation components, the operation is complicated, which affects the maintenance efficiency of the equipment. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a high-efficiency heat dissipation transformer rectifier device. This addresses the issue that while some existing devices employ a bottom-up airflow cooling method, the heat dissipation location is relatively singular, relying mainly on airflow formed by bottom air intake and top exhaust. This makes it difficult to comprehensively cover all areas of the rectifier transformer, especially for parts such as the sides of the transformer, where the heat dissipation effect is poor. Furthermore, the installation and disassembly of some heat dissipation components are not convenient, and when maintenance or replacement of heat dissipation components is required, the operation is complicated, affecting the maintenance efficiency of the equipment.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A high-efficiency heat dissipation transformer rectifier device includes a rectifier transformer; the top middle position of the rectifier transformer is attached to the bottom middle position of the heat dissipation frame, a copper pipe is inserted into the inside of the heat dissipation frame, and a cooling fan is fixedly installed at the front and rear ends of the top of the heat dissipation frame, and an adjusting frame is fixedly installed on the left and right sides of the heat dissipation frame. The two adjusting frames are symmetrically designed, and a through groove is opened in the middle of the top of each adjusting frame. A sliding plate is slidably connected in the groove of each adjusting frame, and the two sliding plates are symmetrically designed.

[0010] According to one embodiment of the present invention, each of the adjustment frames is rotatably connected to an adjustment rod at the inner middle position, and each adjustment rod has a threaded shaft.

[0011] According to one embodiment of the present invention, each of the sliding plates has a threaded hole at the middle position of the upper side, and two adjusting rods are respectively inserted into the threaded hole of one sliding plate. The two sliding plates are located on the left and right sides of the rectifier transformer.

[0012] According to one embodiment of the present invention, each of the sliding plates has a mounting groove in the middle of its side, and an auxiliary fan is fixedly installed in the mounting groove of each sliding plate. The two auxiliary fans are located on the left and right sides of the rectifier transformer.

[0013] According to one embodiment of the present invention, the left and right sides of the rectifier transformer are respectively attached to the inner side of a sliding plate, and the inner sides of the two auxiliary fans are respectively located at the middle of the left and right sides of the rectifier transformer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This device creates a multi-position heat dissipation structure by installing a heat sink with copper pipes and a cooling fan on the top of the rectifier transformer, and sliding plates with auxiliary fans on its left and right sides. The copper pipes on the top can quickly absorb the heat from the rectifier transformer, and the cooling fan accelerates heat dissipation. The auxiliary fans on both sides blow air directly onto the sides of the transformer, enhancing airflow and effectively removing heat from the sides. This multi-directional synergy significantly improves the overall heat dissipation effect and avoids localized overheating.

[0016] The sliding plate and the adjusting frame in the device are assembled by sliding connection and threaded connection of adjusting rod. When it is necessary to add or remove auxiliary fans or other components, simply rotate the adjusting rod to make the sliding plate slide along the slide groove of the adjusting frame, so as to separate or fit the sliding plate with the rectifier transformer. The operation is simple and convenient, which reduces the difficulty of maintenance and replacement of components and improves the maintenance efficiency of the equipment.

[0017] The position of the sliding plate can be adjusted by rotating the adjusting rod, so that the sliding plate can fit the left and right sides of rectifier transformers of different widths and specifications, ensuring that the auxiliary fan can always blow air towards the middle of the side of the transformer, thus enhancing the adaptability of the device to rectifier transformers of different specifications.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a high-efficiency heat dissipation transformer rectifier device, including a rectifier transformer 1; the top middle position of the rectifier transformer 1 is attached to the bottom middle position of the heat sink 2, a copper pipe 201 is inserted through the inside of the heat sink 2, and a cooling fan 202 is fixedly installed at the front and rear ends of the top of the heat sink 2, and an adjusting bracket 203 is fixedly installed on the left and right sides of the heat sink 2. The two adjusting brackets 203 are symmetrically designed, and a through groove is opened in the middle of the top of each adjusting bracket 203. A sliding plate 204 is slidably connected in the groove of each adjusting bracket 203, and the two sliding plates 204 are symmetrically designed.

[0029] Each adjusting frame 203 has an adjusting rod 205 rotatably connected to its inner center position, and each adjusting rod 205 has a threaded rod body.

[0030] Each sliding plate 204 has a threaded hole at the center of its upper side, and two adjusting rods 205 are respectively inserted into the threaded holes of one sliding plate 204. The two sliding plates 204 are located on the left and right sides of the rectifier transformer 1.

[0031] Each sliding plate 204 has a mounting groove in the middle of its side, and an auxiliary fan 206 is fixedly installed in the mounting groove of each sliding plate 204. The two auxiliary fans 206 are located on the left and right sides of the rectifier transformer 1.

[0032] The rectifier transformer 1 is attached to the inner side of a sliding plate 204 on its left and right sides, and the inner sides of the two auxiliary fans 206 are located in the middle of the left and right sides of the rectifier transformer 1, respectively.

[0033] When using:

[0034] Place the rectifier transformer 1 in a suitable position, and attach the bottom center of the heat sink 2 to the top center of the rectifier transformer 1 to complete the initial positioning of the heat sink 2.

[0035] Next, rotate the two adjusting rods 205 respectively, and use the threaded transmission to drive the sliding plate 204 to slide along the sliding groove of the adjusting frame 203 until the inner side of the sliding plate 204 is in contact with the left and right sides of the rectifier transformer 1, thus completing the positioning and clamping of the sliding plate 204. The heat sink 2 is then clamped and fixed above the rectifier transformer 1 for easy disassembly.

[0036] When the device is working, part of the heat generated by the rectifier transformer 1 is transferred to the heat sink 2 at the top. The copper tube 201 inside the heat sink 2 quickly absorbs the heat. At the same time, the cooling fans 202 at the front and rear ends of the top of the heat sink 2 start, accelerating the airflow around the heat sink 2 and quickly dissipating the heat absorbed by the copper tube 201 to the outside.

[0037] The auxiliary fans 206 on the left and right sides start simultaneously, blowing air onto the left and right sides of the rectifier transformer 1 to accelerate the air circulation on the sides of the transformer, and promptly remove the heat generated on the sides. Together with the heat dissipation structure on the top, they work to achieve efficient heat dissipation at multiple locations.

While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments.
