Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a power transformer with rapid heat dissipation. Background Art

[0002] A power transformer is a static electrical device that is used to convert an AC voltage (current) of a certain value into another or several different voltages (currents) of the same frequency. When AC is passed through the primary winding, an alternating magnetic flux is generated. The alternating magnetic flux induces an AC electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns. Its main function is to transmit electrical energy. The power transformer needs to generate a lot of heat during operation. Excessive temperature will affect the efficiency of voltage conversion and cause increased losses. Therefore, the design of the power transformer attaches great importance to heat dissipation performance.

[0003] A Chinese invention patent with publication number CN112635164A discloses an electric transformer, including a heat dissipation mechanism and a dustproof mechanism, wherein the shielding mechanism includes a heat dissipation frame, a heat dissipation motor, a pulley shaft and a fan blade, the heat dissipation motor is fixedly connected to the right end of the heat dissipation frame, the pulley shaft is fixedly connected to the output shaft of the heat dissipation motor, the fan blade is fixedly connected to the left end of the pulley shaft, and the pulley shaft is rotatably connected to the heat dissipation frame, the dustproof mechanism includes a dustproof plate, a friction rod and a friction wheel, the friction rod is fixedly connected to the upper end of the dustproof plate, the friction rod and the friction wheel are frictionally transmitted, and a sliding rod is provided on the friction rod. The device can quickly dissipate heat when the temperature of the electric transformer is too high to prevent the temperature of the electric transformer from being too high, and can also close the heat dissipation holes when rapid heat dissipation is not required to prevent a large amount of garbage, dust and small animals from entering the device.

[0004] However, in the above technical solution, the dustproof plate can only close the heat dissipation holes when the heat dissipation is stopped to achieve the dust-proof effect. During heat dissipation, the friction between the fan blades and the air will make the fan blades charged. The charged blades will capture the tiny dust particles in the air. The dust will gradually accumulate on the fan blades, causing the fan speed to slow down. Over time, even after the dust is cleaned, the fan blades will have different degrees of residual dust for a long time, resulting in different dust weights, and finally causing the fan motor to deviate axially, affecting the heat dissipation effect of the fan blades. At this time, the fan blades often need to be cleaned or replaced regularly, increasing the workload. Utility Model Content

[0005] Based on this, in order to solve the problem that the long-term dust accumulation of the fan blades will affect the heat dissipation effect of the fan blades during heat dissipation, and the fan blades need to be cleaned or replaced regularly, which increases the workload, the purpose of the utility model is to provide a power transformer with rapid heat dissipation, and its specific technical solution is as follows:

A plurality of heat dissipation fins 11 are evenly distributed around the transformer body 1, which can effectively dissipate heat; the heat dissipation box body 2 is fixedly connected to the bottom end of the transformer body 1. By setting the heat dissipation box body 2, it cooperates with the heat dissipation fins 11 on the transformer body 1 to achieve the effect of fast heat dissipation. A heat dissipation cavity 21 is arranged in the heat dissipation box body 2. The heat dissipation cavity 21 comprises a liquid inlet passage 211, a heat dissipation passage 212 and a liquid discharge passage 213. The liquid inlet passage 211, the heat dissipation passage 212 and the liquid discharge passage 213 are connected in sequence.

When blockage occurs, unscrew the blocking piece 22 to dredge it, making the dredging process more convenient and quick. When heat dissipation is needed, tighten the blocking piece 22, and pass chilled water. The chilled water enters from the liquid inlet passage 211 and reaches the drainage passage 213 through the heat dissipation passage 212 for discharge; when the heat dissipation is completed, unscrew all the blocking pieces 22, and the chilled water quickly flows out from the penetration and the drainage passage 213. The whole operation process is simple and quick, and the effect of rapid heat dissipation is achieved.
