Description

A transformer heat dissipation device Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, specifically to a transformer heat dissipation device. Background Technology

[0002] In power systems, transformers are the core equipment for realizing the transmission and distribution of electrical energy. They achieve voltage level conversion through the principle of electromagnetic induction, and inevitably generate a lot of heat during their operation.

[0003] According to relevant research, when the transformer temperature rises by 8-10℃, the aging rate of its insulation material doubles. In terms of performance, the increase in temperature leads to an increase in winding resistance, further aggravating power loss and reducing the transformer's operating efficiency. The insulation material ages faster at high temperatures, its mechanical strength decreases, leading to deterioration of insulation performance, increasing the risk of winding short circuits, and shortening the transformer's service life. Therefore, a cooling structure should be designed to improve the heat dissipation effect of the transformer in order to maintain its operating performance and service life. In view of this, we propose a transformer heat dissipation device. Summary of the Invention

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please refer to Figures 1-6. The present invention will describe the above technical solution in detail through the following embodiments:

[0031] The transformer heat dissipation device in this embodiment is applicable to the transformer body 1 with an external protective box 3 installed on the outside. Most of the current external protective boxes 3 are equipped with ventilation windows 31 on the box body, and exhaust fans are used to exhaust heat. However, the temperature environment inside the box body is uniform, and the exhaust efficiency and effect of a single exhaust fan are not high.

[0032] As shown in Figures 1-3, the heat dissipation unit 2 is installed on the side and rear panel inside the outer protective box 3. It should be noted that there is a height difference between the heat dissipation unit 2 and the ventilation window 31. They are generally located at the upper and lower ends of the transformer body 1, respectively, to obtain airflow over the surface of the transformer body 1, thereby effectively removing heat.

[0033] Specifically, as shown in Figures 2 and 4-6, the heat dissipation part 2 specifically includes a mounting plate 23 that can be detachably installed inside the side rear plate, and an outer cover plate 21 that can be detachably installed outside the mounting plate 23. In this embodiment, there are outwardly protruding locking blocks 231 at both ends of the mounting plate 23, and there are locking grooves 211 on the upper and lower sides of the outer cover plate 21. The outer cover plate 21 can be slidably inserted into the locking blocks 231 through the locking grooves 211, that is, installed on the outside of the mounting plate 23.

[0034] To further absorb internal heat and improve heat exchange efficiency, this embodiment has the structure shown in Figures 5 and 6. A heat-conducting fin 24 is horizontally installed between the outer cover plate 21 and the mounting plate 23. A heat-conducting copper tube 26 with a continuous S-shaped structure is installed on the heat-conducting fin 24 through the mounting vertical hole 241. The outer cover plate 21 has air outlets 214 on both sides corresponding to the positions of the heat-conducting fins 24. That is, the flowing air can enter the air outlets 214 through the heat-conducting fins 24 and then be discharged from the exhaust duct 25.

[0035] In this embodiment, for ease of assembly and disassembly, the exhaust duct 25 is detachably installed at the air outlets 214 on both sides, and the air outlets of the exhaust duct 25 are located outside the outer protective box 3. To improve airflow efficiency, a cavity cover 213 for installing the exhaust fan 22 is provided on the outer cover plate 21, and the outer cover plate 21 has through holes 212 corresponding to the heat-conducting fins 24. In this embodiment, two exhaust fans 22 are provided. In other embodiments, they can be installed in the middle of the outer cover plate 21. The purpose is to allow airflow to pass over the surface of the heat-conducting copper pipe 26 and the heat-conducting fins 24 after heat conduction, so that heat is quickly carried away, thereby improving the heat dissipation efficiency. Combined with the heat conduction of the heat-conducting copper pipe 26 and the heat-conducting fins 24 to the ambient temperature, the internal heat dissipation effect can be improved.

[0036] In this embodiment, to further improve the heat dissipation effect, the heat-conducting copper pipe 26 is designed with external liquid-conducting hoses 27 at both ends. A coolant tank equipped with a liquid pump can be installed separately inside the outer protective box 3, so that the coolant can enter the heat-conducting copper pipe 26 for circulation and heat exchange under the action of the liquid pump. This part of the liquid pump can operate intermittently to maintain a good heat conduction effect.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
