Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer equipment technology, specifically a heat dissipation device for dry-type transformers. Background Technology
[0002] Dry-type transformers are a widely used type of transformer in power systems. They are extensively used in distribution transformers, prefabricated substations, and other fields to provide reliable power supply to users. In industrial enterprises, dry-type transformers are used to provide power to various production equipment, such as machine tools, cranes, and injection molding machines. Commercial centers, office buildings, hotels, and other places require large amounts of power. Due to their fire resistance, environmental friendliness, and ease of installation, dry-type transformers are highly valued. However, because they need to handle large amounts of power, their continuous operation can lead to overheating and potential explosions or combustion due to heat dissipation issues and external temperatures. Therefore, heat dissipation is extremely important for transformers. Current transformer heat dissipation devices are usually integrated with the transformer itself, resulting in a larger transformer size and more complicated disassembly and maintenance, which presents technical defects and requires improvement. Utility Model Content
[0003] To address the aforementioned issues, this invention provides a heat dissipation device for dry-type transformers that is easy to assemble and disassemble, has more efficient heat dissipation, is easier to maintain, and can be installed and processed independently.
[0004] To achieve the above objectives, this utility model provides a heat dissipation device for a dry-type transformer, including a fixed frame. Multiple heat dissipation ribs are arranged horizontally from top to bottom within the front and rear ends of the fixed frame. A fixing device protrudes from the upper end of the fixed frame. The fixing device includes a fixing plate with a groove in the middle. Mounting plates extend from both sides of the groove, and mounting holes are provided on the mounting plates. A heat-conducting pipe is installed in the groove. Both ends of the heat-conducting pipe extend downwards along both sides of the fixed frame. The extended ends of the heat-conducting pipe penetrate and are embedded in the heat dissipation ribs on both sides of the fixed frame. A cover plate is provided at the upper end of the groove, positioned above the heat-conducting pipe. A fan is provided in the middle of the fixed frame, positioned between the heat dissipation ribs on both sides.
[0005] Preferably, the fixing frame is a rectangular frame structure with openings at both the front and rear ends and a hollow interior.
[0006] Preferably, positioning plates protrude from the four corners of the inner side of the fixed frame, and a fan is installed through the positioning plates. The fan includes a support frame, with fan blades installed in the middle of the support frame. Multiple connecting plates corresponding to the positioning plates protrude from the circumference of the support frame. The support frame is connected to the positioning plates through the connecting plates and is placed in the middle of the fixed frame. Preferably, the heat dissipation ribs are respectively arranged on the front and rear sides of the fixed frame and embedded between the fixed frame bodies, and the multiple heat dissipation ribs are arranged sequentially from top to bottom.
[0007] Preferably, there are at least three heat pipes, all of which extend downwards continuously. The extension tubes of the heat pipes are embedded in the heat dissipation ribs on both sides of the fixed frame, and the cover plate is a heat-conducting plate.
[0008] The beneficial effects of this utility model are as follows: by setting heat pipes and heat dissipation fins, the contact area between the object and the surrounding environment can be increased, thereby improving heat dissipation efficiency. The shape and array layout of the heat dissipation fins can promote the convection of air or other fluids and accelerate the transfer of heat. The heat dissipation fins themselves have a certain thermal conductivity. Through the contact between the heat pipes and the transformer, heat is conducted to the heat dissipation fins. Then, the fan installed in the middle of the fixed frame promotes air circulation and allows the heat dissipation fins to dissipate heat in the form of radiation. The heat dissipation fins can evenly distribute heat on the surface of the object, avoid local overheating, improve the stability of heat dissipation, and make heat dissipation more uniform. At the same time, the addition of a mounting plate at the upper end of the fixed frame makes it easier to install this device and the transformer. During installation, it can be installed at the lower end of the transformer to avoid the transformer occupying volume laterally. Disassembly is more convenient and maintenance is more convenient.

[0015] Combination Figure 1-3This utility model provides a heat dissipation device for a dry-type transformer, including a fixed frame 1. Multiple heat dissipation ribs 2 are arranged horizontally from top to bottom within the front and rear ends of the fixed frame 1. A fixing device protrudes from the upper end of the fixed frame 1. The fixing device includes a fixing plate 3. A groove 302 is provided in the middle of the fixing plate 3. Mounting plates 301 extend from both sides of the groove 302. The mounting plates 301 have mounting holes. A heat-conducting pipe 5 is installed in the groove 302. Both ends of the heat-conducting pipe 5 extend downwards along both sides of the fixed frame 1. The extended ends of the heat-conducting pipe 5 penetrate and are embedded in the heat dissipation ribs 2 on both sides of the fixed frame 1. A cover plate 4 is provided at the upper end of the groove 302, positioned above the heat-conducting pipe 5. A fan is provided in the middle of the fixed frame 1, positioned in the middle of the heat dissipation ribs 2 on both sides.
[0016] Furthermore, the fixed frame 1 is a rectangular frame structure with openings at both the front and rear ends and a hollow interior.

The support frame 6 is connected to the positioning plates 101 through the connecting plates 601 and is placed in the middle of the fixed frame 1.
[0018] Furthermore, the heat dissipation ribs 2 are respectively arranged on the front and rear sides of the fixed frame 1 and embedded between the fixed frame 1, and multiple heat dissipation ribs 2 are arranged sequentially from top to bottom.

The extension tubes of the heat pipes 5 are embedded in the heat dissipation ribs 2 on both sides of the fixed frame 1, and the cover plate 4 is a heat-conducting plate. By setting the heat pipes 5 and the heat dissipation ribs 2, the contact area between the object and the surrounding environment can be increased, thereby improving the heat dissipation efficiency. The shape and array layout of the heat dissipation ribs 2 can promote the convection of air or other fluids and accelerate the heat transfer. The heat dissipation ribs 2 themselves have a certain thermal conductivity. Through the contact between the heat pipes 5 and the transformer, the heat is conducted to the heat dissipation ribs 2. Then, the fan installed in the middle of the fixed frame 1 promotes air circulation and causes the heat dissipation ribs 2 to dissipate the heat in the form of radiation. The heat dissipation ribs 2 can evenly distribute the heat on the surface of the object, avoid local overheating, improve the stability of the heat dissipation effect, and make the heat dissipation more uniform. At the same time, the addition of the mounting plate 301 at the upper end of the fixed frame 1 makes it easier to install this device and the transformer.
