Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a transformer cooling frame. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux interlinked with the coil changes. This is the principle of mutual induction; a transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.

[0003] The existing cooling method of transformers is usually self-cooling. In a high temperature environment, the heat generated by the loss of the coil and the core will cause the temperature of the transformer body to rise sharply, thereby causing the internal insulation material of the coil to age rapidly and the insulation performance to drop sharply, which will cause the transformer to burn out due to the degradation of insulation performance. For this reason, we propose a transformer heat sink. Utility Model Content

[0004] In view of the above problems, the utility model provides a transformer heat sink, which can solve the problems existing in the above background technology.

[0005] The technical solution of the utility model is:

[0006] A transformer cooling frame comprises a transformer, wherein a fan frame is arranged on the outside of the transformer, a temperature control switch is arranged on the inside of the transformer, a connection terminal is arranged on the surface of the fan frame, and a cooling fan is arranged on the inside of the fan frame.

[0007] In a further technical solution, a filtering mechanism is provided on the surface of the fan frame.

[0008] In a further technical solution, the temperature control switch and the heat dissipation fan are connected in series.

[0009] In a further technical solution, the connection line between the temperature control switch and the heat dissipation fan is connected to the wiring terminal, and the input end of the wiring terminal is connected to the mains.

[0010] In a further technical solution, the filtering mechanism comprises a limit block, the inner side of which is movably connected to a movable filter plate, the surface of which is symmetrically provided with connecting positioning blocks, and a positioning bolt is connected between the connecting positioning block and the limit block.

[0011] In a further technical solution, the outer side of the edge surface of the movable filter plate is in contact with the inner side of the limit block, and one side of the movable filter plate is in contact with the surface of the fan frame.

[0012] In a further technical solution, the cross-sectional shape of the connecting positioning block is L-shaped, and the inner side of the connecting positioning block fits with the surfaces of the limiting block and the fixed positioning block.

[0013] The beneficial effects of the utility model are:

[0014] 1. By supplying power to the transformer input terminals, the transformer output terminal generates voltage and carries the load. After a certain period of operation, the transformer begins to heat up. When the temperature reaches the working temperature of the temperature control switch, the temperature control switch closes, causing the temperature control switch, the cooling fan and the terminals to form a complete loop, and the cooling fan starts to work; because the cooling fan is facing the window between the transformer coils, the wind blows to the surface of the transformer coil to form forced convection, causing the heat continuously generated on the surface of the transformer coil to be blown away by the wind, thereby achieving the purpose of heat dissipation;

[0015] 2. Through the filtering mechanism, the air can be filtered while dissipating heat, which can effectively prevent dust from adhering to the outer surface of the transformer and affecting the overall heat dissipation effect. The overall structure is simple and the operation is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

After a certain period of operation, the transformer 1 begins to heat up. When the temperature reaches the working temperature of the temperature control switch 2, the temperature control switch 2 is closed, so that the temperature control switch 2, the heat dissipation fan 5 and the terminals form a complete loop, and the heat dissipation fan 5 starts to work. Similarly, when the load of the transformer 1 is reduced, the transformer 1 begins to cool down. When the temperature drops below the working temperature of the temperature control switch 2, the temperature control switch 2 is disconnected, so that the temperature control switch 2, the heat dissipation fan 5 and the terminals are disconnected, and the heat dissipation fan 5 stops working.

[0026] In another embodiment, if Figure 1 As shown, a filter mechanism 6 is provided on the surface of the fan frame 3 .

[0027] When the heat dissipation fan 5 is in use, the air can flow. At this time, the filter mechanism 6 can filter the air to prevent dust from covering the surface of the transformer 1 after long-term use, which is easy to operate.

[0028] In another embodiment, if Figure 1 As shown, the temperature control switch 2 and the heat dissipation fan 5 are connected in series.

[0029] The temperature control switch 2 can be connected in series with the heat dissipation fan 5, so that when the temperature control switch 2 is turned on and the circuit is connected, the heat dissipation fan 5 can be started automatically, which is convenient to operate.

[0030] In another embodiment, if Figure 1 As shown, the connection line between the temperature control switch 2 and the heat dissipation fan 5 is connected to the wiring terminal 4, and the input end of the wiring terminal 4 is connected to the mains.

[0031] It is convenient for the whole to form a circuit, easy to switch on and off by itself, and easy to operate.

[0032] In another embodiment, if Figure 2 As shown, the filtering mechanism 6 includes a limit block 7, the inner side of which is movably connected to a movable filter plate 9, and the surface of the movable filter plate 9 is symmetrically provided with connecting positioning blocks 10, and a positioning bolt 11 is connected between the connecting positioning block 10 and the limit block 7.

[0033] When the movable filter plate 9 needs to be disassembled and cleaned, the positioning bolt 11 is rotated and disassembled so that the positioning bolt 11 is disengaged from the inside of the fixed positioning block 8 and the connecting positioning block 10, and then the connecting positioning block 10 is moved laterally to drive the movable filter plate 9 to move laterally so that the movable filter plate 9 is disengaged from the inner side of the limit block 7, so that the movable filter plate 9 can be quickly disassembled and cleaned, and the operation is convenient.

[0034] In another embodiment, if Figure 2 As shown, the outer side of the edge surface of the movable filter plate 9 is in contact with the inner side of the limiting block 7 , and one side of the movable filter plate 9 is in contact with the surface of the fan frame 3 .

[0035] The movable filter plate 9 can be stably placed between the fan frame 3 and the limiting block 7 for use, and the operation is convenient.

[0036] In another embodiment, if Figure 2 As shown, the cross-sectional shape of the connecting positioning block 10 is L-shaped, and the inner side of the connecting positioning block 10 is in contact with the surfaces of the limiting block 7 and the fixed positioning block 8 .

[0037] The connection positioning block 10 can be stably connected with the limiting block 7 and the fixed positioning block 8, thereby improving the connection stability.

[0038] The working principle of the utility model: during use, by supplying power to the wiring terminals at the input end of the transformer 1, the output end of the transformer 1 generates voltage and carries the load. After a certain period of operation, the transformer 1 starts to heat up. When the temperature reaches the working temperature of the temperature control switch 2, the temperature control switch 2 is closed, so that the temperature control switch 2, the heat dissipation fan 5 and the wiring terminals form a complete loop, and the heat dissipation fan 5 starts to work. Similarly, when the load of the transformer 1 is reduced, the transformer 1 starts to cool down. When the temperature drops below the working temperature of the temperature control switch 2, the temperature control switch 2 is disconnected, so that the temperature control switch 2, the heat dissipation fan 5 and the wiring terminals are disconnected, and the heat dissipation fan 5 starts to work. 5 stops working, and during the operation of the heat dissipation fan 5, the air can be filtered through the movable filter plate 9 to prevent dust from covering the surface of the transformer 1 and affecting the heat dissipation effect of the transformer 1. At the same time, when it is necessary to disassemble and clean the movable filter plate 9, the positioning bolts 11 are rotated and disassembled to disengage the positioning bolts 11 from the fixed positioning block 8 and the inside of the connecting positioning block 10, and then the connecting positioning block 10 is moved horizontally to drive the movable filter plate 9 to move horizontally, so that the movable filter plate 9 is disengaged from the inner side of the limiting block 7, so that the movable filter plate 9 can be quickly disassembled and cleaned, and the operation is convenient.
