Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a high-frequency transformer resistant to high temperatures. Background Art

[0002] The high-frequency transformer is the most important component of the switching power supply. The existing patent is a high-temperature resistant high-frequency transformer, and the patent publication number CN214672132U includes an outer iron core and an inner iron core connected in one piece, and a coil winding wound on the inner iron core. The inner wall of the coil winding is provided with a heat-conducting copper strip, and the surface of the coil winding is wrapped with heat-conducting silica gel. The outer side of the outer iron core is provided with a foam heat sink, and the surface of the foam heat sink is provided with a concave wind slot, and the inner wall of the foam heat sink is provided with a claw. The heat in the coil winding is dissipated, and the heat resistance effect is improved.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: although the effective heat dissipation of the coil windings inside the transformer can be achieved, the dissipated heat will eventually be discharged through the cooling fins on the transformer housing. However, since the cooling fins are generally arranged and installed in a concentrated manner, the heat on the cooling fins is relatively concentrated and cannot be dissipated, resulting in the temperature of the transformer housing gradually increasing, which in turn easily causes the transformer to have poor high temperature resistance. Therefore, we propose a high-temperature resistant high-frequency transformer to solve the above-mentioned problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5 The utility model provides a technical solution: a high-frequency transformer resistant to high temperature, comprising:

[0030] The transformer body 100 includes a transformer housing 101 and a coil winding arranged inside the transformer housing 101, and heat dissipation fins 102 are arranged on four outer surfaces of the transformer housing 101;

[0031] The shell heat dissipation component 200 includes a water tank 201 fixed on the lower surface of the transformer shell 101, and a serpentine heat exchange coil 202 respectively coiled on the four inner walls of the transformer shell 101 for absorbing the heat dissipated by the transformer shell 101, and two adjacent serpentine heat exchange coils 202 are connected. The shell heat dissipation component 200 also includes a water pump 203 fixed at the bottom of the water tank 201, and the liquid outlet end of the water pump 203 is provided with a liquid outlet pipe 204 extending to the upper surface of the water tank 201, and the end of the liquid outlet pipe 204 away from the water pump 203 extends to the interior of the transformer shell 101 and is connected to a serpentine heat exchange coil 202. The outer surface of the transformer shell 101 is provided with a return pipe 205 extending to the interior of the water tank 201, and the top end of the return pipe 205 extends to the interior of the transformer shell 101 and is connected to a serpentine heat exchange coil 202.

[0032] Among them, by setting up the shell heat dissipation component 200, the high-frequency transformer can start the water pump 203 during actual use to transport the cooling water in the water tank 201 into the four serpentine heat exchange coils 202 through the liquid outlet pipe 204 to effectively exchange the heat generated by the transformer shell 101, thereby effectively solving the defect of the prior art that the transformer shell 101 cannot be cooled.

[0033] See also Figure 2 , Figure 3 The inner wall of the transformer housing 101 is provided with a thermal insulation pad 206, and the material of the thermal insulation pad 206 is melamine foam. The four outer surfaces of the thermal insulation pad 206 are provided with serpentine mounting grooves interconnected with each other, and the four serpentine heat exchange coils 202 are respectively fixed on the inner walls of the four serpentine mounting grooves; the thermal insulation pad 206 can prevent the heat generated by the transformer housing 101 from being transferred to the inside of the transformer body 100.

[0034] See also Figure 1 , Figure 4 The outer surface of the return pipe 205 is equidistantly provided with a plurality of heat sinks 207 for dissipating heat from the liquid passing through the return pipe 205, and the material of the heat sink 207 is pure copper; when the cooling water after heat exchange passes through the return pipe 205, the heat sink 207 can make the cooling water with increased temperature exchange heat with the outside air, thereby achieving the purpose of cooling the cooling water after heat exchange, thereby reducing the temperature of the cooling water entering the water storage tank 201, ensuring that the cooling water can circulate and dissipate heat to the transformer housing 101.

[0035] See also Figure 2-5 The outer surface of the transformer housing 101 is provided with a blowing assembly 300 for dissipating the heat derived from the heat dissipation fins 102 .

[0036] The blowing assembly 300 includes an annular tube 301 fixed on the outer surface of the top end of the transformer housing 101, and four groups of blowing pipes 302 embedded in the lower surface of the annular tube 301. The surfaces of the liquid outlet pipe 204 and the return pipe 205 are both provided with a first connecting tube 303, and the outer surface of the first connecting tube 303 is embedded with a second connecting tube 304.

[0037] An air delivery pipe 305 is embedded in the end of the second connecting tube 304 , and both ends of the air delivery pipe 305 are respectively connected to the second connecting tube 304 and the annular tube 301 .

[0038] The inner wall of the first connecting tube 303 is rotatably provided with a rotating shaft 306 extending into the second connecting tube 304, the outer surface of the rotating shaft 306 is fixedly provided with an impeller 307, and the end of the rotating shaft 306 is provided with a blowing fan blade 308, and the outer surface of the second connecting tube 304 is provided with a plurality of air inlet holes 309 in a circular array.

[0039] Among them, by setting up the blowing component 300, when the water pump 203 inputs the cooling water in the water tank 201 into the liquid outlet pipe 204, the cooling water can drive the blowing fan blades 308 to rotate, thereby blowing air toward the cooling fins 102 through the blowing pipe 302 on the annular tube 301, effectively accelerating the flow of air around the cooling fins 102, thereby effectively improving the heat dissipation performance of the cooling fins 102.

[0040] When working, in actual use, the high-frequency transformer can start the water pump 203 to transport the cooling water in the water tank 201 into the four serpentine heat exchange coils 202 through the liquid outlet pipe 204 to effectively exchange heat generated by the transformer housing 101. At the same time, when the cooling water after heat exchange passes through the return pipe 205, the cooling water with increased temperature can exchange heat with the outside air under the action of the heat sink 207, so as to achieve the purpose of cooling the cooling water after heat exchange, thereby reducing the temperature of the cooling water entering the water tank 201, ensuring that the cooling water can circulate and dissipate heat for the transformer housing 101. In addition, when the water pump 203 inputs the cooling water in the water tank 201 into the liquid outlet pipe 204, the cooling water can first enter the first connecting cylinder 303, The impeller 307 in the first connecting tube 303 is driven to rotate, and the rotation of the impeller 307 drives the rotating shaft 306 to rotate, and the rotation of the rotating shaft 306 drives the fan blades 308 to rotate, so that airflow is generated in the second connecting tube 304 and transported into the interior of the annular tube 301 through the air supply pipe 305, and finally blows air toward the heat dissipating fins 102 through the air blowing pipe 302 on the annular tube 301, effectively accelerating the flow of air around the heat dissipating fins 102, thereby effectively improving the heat dissipation performance of the heat dissipating fins 102. At the same time, when the cold zone water passes through the return pipe 205, it can drive another impeller 307 to rotate, so that the other air supply pipe 305 sends the airflow into the annular tube 301, thereby making the transformer body 100 have good high temperature resistance.
