Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a high-efficiency heat dissipation transformer with multi-layer heat dissipation fins. Background Technology

[0002] As the "power hub" within the factory, the transformer's core function is to convert electrical energy into different voltage levels, providing safe and suitable power to various production equipment, lighting, and auxiliary systems within the factory, thus ensuring the normal operation of the factory.

[0003] As a core piece of equipment in the power system, transformers generate a lot of heat during operation due to core and winding losses. If the heat cannot be dissipated in time, the internal temperature of the transformer will rise, which will not only affect the stability of power supply, but may also cause serious faults such as insulation aging and winding burnout.

[0004] A related technology (announcement number: CN203799787U) discloses a finned heat dissipation transformer. The disclosed technical solution is as follows: a capillary wick is provided inside the tube, and the capillary wick contains an evaporation-condensation working fluid. One end of the copper tube is the evaporation end, and the other end is the condensation end. When one end of the copper tube is heated, the liquid in the capillary wick evaporates rapidly. The vapor flows to the other end under a small pressure difference and releases heat, then condenses back into liquid. The liquid then flows back to the evaporation end along the capillary wick by the action of capillary force. This cycle continues, and heat is transferred from one end of the heat pipe to the other end.

[0005] The aforementioned disclosed technical solutions reveal the following problems: Currently, most transformers employ a single-layer heat dissipation fin structure with a relatively large fin spacing (typically 15-20mm), resulting in a heat dissipation area sufficient only for low-load conditions (e.g., below 60% of rated load). When the transformer operates under high load (e.g., during peak summer electricity consumption, with a load rate of 80%-100%), the heat dissipation area of ​​the single-layer fins cannot quickly conduct heat, leading to a rapid increase in the transformer's body temperature. To address this, we propose a high-efficiency heat dissipation transformer with multi-layer heat dissipation fins.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0007] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the transformer heat dissipation problem in the prior art, this utility model provides a high-efficiency heat dissipation transformer with multi-layered heat dissipation fins. It employs a multi-layered, stacked heat dissipation fin combination and a heat dissipation fin heat conduction circulation structure to improve the transformer's heat dissipation effect. The specific technical solution is as follows: A high-efficiency heat dissipation transformer with multi-layer heat dissipation fins includes a transformer body. The outer wall of the transformer body is uniformly provided with main layer heat dissipation fins, and a secondary layer heat dissipation fin connected to the transformer body is embedded between every two adjacent main layer heat dissipation fins. A refrigerant pipe is spirally laid on the outer wall of the transformer body, penetrating all the main layer heat dissipation fins. The transformer body is provided with a refrigeration system for providing circulating refrigerant into the refrigerant pipe. All the secondary layer heat dissipation fins are uniformly distributed on both sides of the refrigerant pipe.

[0008] In the above technical solution, heat dissipation microchannels are opened on the surface of the main heat dissipation fins and the secondary heat dissipation fins. A ventilation duct is sleeved on the outside of the transformer body, and branch pipes corresponding to the heat dissipation microchannels are evenly fixed on the ventilation duct. A fan that provides airflow to the ventilation duct is fixed on the top of the transformer body.

[0009] The outer wall where the refrigerant pipe meets the main heat dissipation fins is uniformly provided with micro-protrusion roughening points.

[0010] The surfaces of both the main heat dissipation fins and the secondary heat dissipation fins are coated with a black anodized coating.

[0011] The refrigeration system includes a liquid storage tank fixed to the outer wall of the transformer body, and a compressor, a condenser, a throttling valve and an evaporator connected in sequence are fixed on the liquid storage tank.

[0012] The refrigeration system is a compression refrigeration system.

[0013] The evaporator has a coil structure and is detachably embedded in the inner wall of the liquid storage tank.

[0014] The outer wall of the evaporator coil is integrally formed with spiral-shaped turbulence ribs.

[0015] The spacing between two adjacent heat dissipation fins of the main layer is 8-10 mm.

[0016] Compared with the prior art, the beneficial effects of this utility model are: First, the main heat dissipation fins and the secondary heat dissipation fins are arranged in an alternating pattern, which brings significant heat dissipation advantages to the main transformer. The main heat dissipation fins are fixed evenly in sequence on the middle of the circumferential outer wall of the transformer body. The secondary heat dissipation fins are cleverly embedded in the interlayer formed between every two main heat dissipation fins. This design greatly increases the heat dissipation area, allowing the transformer to dissipate heat more efficiently during operation, thereby improving the overall heat dissipation effect.

[0017] Second, the refrigerant inside the liquid storage tank circulates along the refrigerant pipes, allowing it to circulate through all the main heat dissipation fins. This process is similar to the human circulatory system, where the refrigeration system continuously removes heat from the transformer body, ensuring that the transformer is always at a suitable operating temperature.

[0018] Third, once the fan is connected to the power supply, the airflow is exhausted through the ventilation ducts and branch pipes, blowing towards the corresponding heat dissipation microchannels. This is like building a highly efficient air-cooling system for the transformer, accelerating the airflow speed on the surface of the heat dissipation microchannels. The rapidly flowing air can quickly carry away the heat from the heat dissipation fins, further improving the transformer's heat dissipation effect. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0022] A high-efficiency heat dissipation transformer with multi-layer heat dissipation fins includes a transformer body 1. Main heat dissipation fins 2 are uniformly arranged circumferentially on the outer wall of the transformer body 1, and a secondary heat dissipation fin 3, connected to the transformer body 1, is embedded between every two adjacent main heat dissipation fins 2. The main heat dissipation fins 2 are uniformly fixed sequentially to the center of the circumferential outer wall of the transformer body 1. A secondary heat dissipation fin 3 is embedded in the interlayer formed between every two main heat dissipation fins 2. The two secondary heat dissipation fins 3 in each interlayer are located on the upper and lower sides of a refrigerant pipe 4. The heat dissipation area is expanded by the main heat dissipation fins 2 and secondary heat dissipation fins 3 covering the surface of the transformer body 1. The staggered space between the main heat dissipation fins 2 and secondary heat dissipation fins 3 achieves a heat dissipation effect.

[0023] The outer wall of the transformer body 1 is circumferentially spirally covered with refrigerant pipes 4 that run through all the main heat dissipation fins 2. A refrigeration system is installed on the transformer body 1 to supply circulating refrigerant to the refrigerant pipes 4. All secondary heat dissipation fins 3 are evenly distributed on both sides of the refrigerant pipes 4. A sleeve fixed to the outer wall of the refrigerant pipes 4 is fitted onto the outer wall of the transformer body 1. The refrigeration system allows the refrigerant to circulate along the refrigerant pipes 4. Through the refrigerant pipes 4 that are in contact with the main heat dissipation fins 2, the heat dissipation effect of the main heat dissipation fins 2 is further improved.

[0024] Among them, the surface of the main heat dissipation fin 2 and the secondary heat dissipation fin 3 are provided with heat dissipation microchannels 5, and some of the heat dissipation microchannels 5 on the main heat dissipation fin 2 and the secondary heat dissipation fin 3 are connected to each other. The transformer body 1 is fitted with a ventilation duct 6, and the ventilation duct 6 is uniformly fixed with branch pipes 7 corresponding to the heat dissipation microchannels 5. The top of the transformer body 1 is fixed with a fan 8 that provides airflow to the ventilation duct 6.

[0025] After the fan 8 is connected to the power supply, the air provided is discharged through the ventilation duct 6 and the branch pipe 7, and blown from the outlet of the branch pipe 7 to the corresponding heat dissipation microchannel 5, which improves the surface flow effect of the heat dissipation microchannel 5, thereby improving the heat dissipation effect of the transformer.

[0026] Micro-protrusions are evenly distributed on the outer wall where the refrigerant pipe 4 fits into the main heat dissipation fins 2. These micro-protrusions further fill the tiny gaps and enhance heat conduction.

[0027] Both the main heat dissipation fin 2 and the secondary heat dissipation fin 3 are coated with a black anodized coating. A porous black oxide film is formed on the surface of the aluminum heat dissipation fins through electrochemical oxidation. The film thickness is typically 5-15 μm, the surface roughness Ra is 0.8-1.6 μm, and the corrosion resistance can be improved by sealing the pores.

[0028] It is worth noting that the refrigeration system includes a liquid storage tank 9 fixed to the outer wall of the transformer body 1. A compressor 10, a condenser 11, a throttling valve 12, and an evaporator 13 are sequentially connected and fixed to the liquid storage tank 9. A circulation pump connected to the refrigerant pipe 4 is installed at the top of the liquid storage tank 9. The circulation pump causes the refrigerant inside the liquid storage tank 9 to circulate along the refrigerant pipe 4, allowing the refrigerant to circulate through all the main heat dissipation fins 2, thus improving the transformer's heat dissipation effect.

[0029] The refrigeration system is a compression refrigeration system.

[0030] The evaporator 13 has a coil structure and is detachably embedded in the inner wall of the liquid storage tank 9.

[0031] In addition, the outer wall of the coil of the evaporator 13 is integrally formed with spiral turbulence ribs. The height of the turbulence ribs is 1-3mm, which are used to increase the contact area between the evaporator 13 and the liquid in the liquid storage tank and to break the liquid flow boundary layer, thereby improving the heat exchange efficiency.

[0032] In addition, the spacing between two adjacent main heat dissipation fins 2 is 8-10mm, and the secondary heat dissipation fins 3 are installed in the gap between adjacent main heat dissipation fins in an interleaved manner. The secondary heat dissipation fins 3 are higher than the main heat dissipation fins 2. The secondary heat dissipation fins 3 and the main heat dissipation fins 2 cover the surface of the transformer body 1 by extending in a staggered manner, increasing the heat dissipation area and thus improving the heat dissipation effect of the transformer.
