Description

Technical Field

[0001] This application relates to the field of heat dissipation technology for power equipment, and in particular to a heat dissipation structure for a box-type transformer. Background Technology

[0002] Power equipment heat dissipation refers to the process of transferring the heat generated by power loss during operation to the external environment in a timely and efficient manner through specific technical means and structural design, so as to maintain the core components of the equipment within a safe and stable operating temperature range.

[0003] Existing box-type transformers mostly rely on natural heat dissipation or simple fan cooling. When the transformer is under high load in summer, the rate of heat accumulation is much greater than the rate of heat dissipation, which can easily cause the temperature of the core components inside the box to exceed the safety threshold, leading to problems such as accelerated insulation aging and reduced equipment operating efficiency. To address these issues, we propose a heat dissipation structure for box-type transformers. Utility Model Content

[0025] Example 2,

[0026] The heat dissipation assembly 2 includes a cavity 201, which is located inside the transformer box body 1. A circulation pipe 202 is fixedly installed on the inner wall of the cavity 201. A support plate 203 is fixedly connected to the outer surface of the transformer box body 1. A pump body 204 is fixedly installed on the upper surface of the support plate 203. The input end of the pump body 204 is fixedly connected to a first pipe 205. One end of the first pipe 205 is fixedly connected to one end of the circulation pipe 202. The output end of the pump body 204 is fixedly connected to a second pipe 206. A heat exchanger 207 is fixedly installed on the upper surface of the support plate 203. The input end of the heat exchanger 207 is connected to the second pipe... The other end of 206 is fixedly connected, the output end of heat exchanger 207 is fixedly connected to the third pipe 208, the upper surface of support plate 203 is fixedly installed with a cooler 209, the other end of the third pipe 208 is fixedly connected to the input end of cooler 209, the output end of cooler 209 is fixedly connected to the fourth pipe 210, the upper surface of support plate 203 is fixedly installed with a water tank 211, the other end of the fourth pipe 210 is fixedly connected to the outer surface of water tank 211, the outer surface of water tank 211 is fixedly connected to the fifth pipe 212, and the other end of the fifth pipe 212 is fixedly connected to the other end of circulation pipe 202.

[0027] In the heat dissipation assembly 2, the cavity 201 inside the transformer box body 1 provides installation space for the circulation pipe 202. The coolant in the circulation pipe 202 can quickly absorb the heat inside the box. The support plate 203 stably supports components such as the pump body 204 and the heat exchanger 207. The pump body 204 drives the coolant to circulate through the first pipe 205 and the second pipe 206. The heat exchanger 207 initially cools the coolant after absorbing heat. The cooler 209 further cools the coolant through the third pipe 208 and the fourth pipe 210. The water tank 211 stores the coolant and achieves circulation back through the fifth pipe 212, forming a high-efficiency liquid cooling heat dissipation circuit.

[0028] The auxiliary component 3 includes a frame 301, which is located on the upper surface of the transformer box body 1. A cooling fan 302 is fixedly installed on the inner wall of the frame 301, and a filter screen 303 is fixedly installed on the inner wall of the frame 301. Two heat dissipation plates 304 are provided on the outer surface of the transformer box body 1. A water inlet pipe 8 is fixedly connected to the upper surface of the water tank 211. A sealing cap 9 is threadedly connected to the outer surface of the water inlet pipe 8. Four support blocks 10 are fixedly connected to the bottom surface of the transformer box body 1.

[0029] In auxiliary component 3, frame 301 fixes cooling fan 302, cooling fan 302 accelerates air circulation inside and outside the box, helps to reduce the temperature inside the box, filter screen 303 prevents dust and impurities from entering the box and affecting equipment operation, two heat dissipation plates 304 increase the heat dissipation area of ​​the outer surface of transformer box body 1 and improve the natural heat dissipation effect, water pipe 8 and sealing cover 9 facilitate the replenishment of coolant and ensure sealing, four support blocks 10 keep transformer box body 1 away from the ground to avoid moisture and corrosion, and heat dissipation indicator light 11 can indicate the working status of the heat dissipation system and improve the ease of use.

[0030] The working principle of this application is as follows:

[0031] The heat generated by the transformer tank body 1 during operation is first absorbed by the coolant in the circulation pipe 202 within its internal cavity 201. The control panel 6 activates the pump 204 on the tray 203. The pump 204 pumps the cooled coolant through the first pipe 205 to the second pipe 206. The coolant then enters the heat exchanger 207 for initial heat dissipation through the second pipe 206, and then flows into the cooler 209 through the third pipe 208 for further cooling. The cooled coolant is then sent to the water tank 211 for temporary storage through the fourth pipe 210, and then flows back to the circulation pipe 212 from the water tank 211. Pipe 202 completes the circulating heat dissipation. At the same time, the cooling fan 302 inside the upper frame 301 of the transformer box body 1 starts to accelerate the air flow inside the box to assist in heat dissipation. The filter screen 303 prevents dust from entering. The heat dissipation plate 304 on the outer surface further increases the heat dissipation area. Two temperature sensors 4 monitor the temperature inside the box in real time and transmit the data to the temperature display board 5. The heat dissipation indicator light 11 indicates the heat dissipation status. The water pipe 8 and the sealing cover 9 facilitate the replenishment of coolant. The support block 10 keeps the transformer box body 1 away from the ground to avoid moisture. The whole system achieves efficient heat dissipation through the synergistic effect of the heat dissipation component 2 and the auxiliary component 3.
