The center of the iron core forms a cavity for accommodating the winding, and the winding is located in the cavity. The transformer of the welding machine will generate a lot of heat when working continuously, which affects the working efficiency. In addition, since there are many parts inside the transformer, it is difficult to use an ordinary screwdriver inside, which makes it inconvenient to disassemble the transformer and perform maintenance. Utility Model Content

[0003] The main purpose of the utility model is to provide a transformer for welding equipment, which can effectively solve the problems in the background technology.

[0004] To achieve the above object, the technical solution adopted by the utility model is: a transformer for welding equipment, comprising a transformer, the left and right sides of the transformer are connected to the circuit board in the welding machine through a mounting mechanism, and a heat dissipation mechanism is arranged on the upper part of the transformer;

[0006] Preferably, the front and rear ends of the clamping rod are slidably connected inside the clamping slot.

[0007] Preferably, the lower end of the card block is mounted on a circuit board in the electric welding machine.

[0008] Preferably, the heat dissipation mechanism includes a heat absorption tube, a heat dissipation box, heat dissipation fins and a water pump, the heat absorption tube is coiled around the outer periphery of the transformer, both ends of the heat absorption tube extend into the heat dissipation box, the heat dissipation box is installed on the upper part of the transformer through a bracket, the lower part of the water pump is installed on the inner bottom wall of the heat dissipation box, the output end of the water pump is connected to one end of the heat dissipation box, and the heat dissipation fins are installed on the upper part of the heat dissipation box.

[0009] Preferably, a partition is installed on the upper side of the interior of the heat dissipation box, and the end of the heat absorption pipe away from the water pump passes through the middle of the partition.

[0010] Preferably, a plurality of cooling fans are installed at one end of the cooling fins away from the cooling box.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By bending the lever, the lever drives the card rod to rotate around the middle of the lever. Because the spring rod pushes the lever to one side, the spring rod will fix it. Therefore, by bending the lever, the card rod can be stuck in the card slot or away from the card slot, so that the transformer can be easily disassembled and installed, and it is convenient to repair it.

[0013] 2. The coolant inside the heat sink is driven by a water pump to circulate inside the heat sink and the heat absorption tube.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a transformer for welding equipment includes a transformer 3. The left and right sides of the transformer 3 are connected to a circuit board in an electric welding machine through a mounting mechanism 2. A heat dissipation mechanism 1 is arranged on the upper part of the transformer 3.

[0021] In this embodiment, the mounting mechanism 2 includes a mounting seat 201, a lever 202, a clamping rod 203, a spring rod 204, a clamping block 205 and a clamping slot 206. The clamping slot 206 is arranged on the left and right sides of the upper part of the clamping block 205. The middle part of the lever 202 is rotatably connected to the upper wall shell of the mounting seat 201, the lower end of the lever 202 is rotatably connected to the upper end of the spring rod 204, the lower end of the spring rod 204 is rotatably connected to the inner bottom wall of the mounting seat 201, the middle part of the clamping rod 203 is fixedly connected to the lower end of the lever 202, the front and rear ends of the clamping rod 203 are slidably connected to the inside of the clamping slot 206, and the lower end of the clamping block 205 is mounted on the circuit board in the electric welding machine.

[0022] Specifically, when the transformer 3 needs to be disassembled, the lever 202 is moved so that the lever 202 drives the locking rod 203 to rotate around the middle of the lever 202. Because the spring rod 204 pushes the lever 202 to one side, the spring rod 204 will fix it. Therefore, by moving the lever 202, the locking rod 203 can be stuck in the locking slot 206 or away from the locking slot 206, so that the transformer 3 can be easily disassembled and installed, and its maintenance can be facilitated.

[0023] In this embodiment, the heat dissipation mechanism 1 includes a heat absorption tube 101, a heat dissipation box 102, heat dissipation fins 103 and a water pump 104. The heat absorption tube 101 is coiled around the outer periphery of the transformer 3, and both ends of the heat absorption tube 101 extend into the heat dissipation box 102. The heat dissipation box 102 is installed on the upper part of the transformer 3 through a bracket, and the lower part of the water pump 104 is installed on the inner bottom wall of the heat dissipation box 102. The output end of the water pump 104 is connected to one end of the heat dissipation box 102. The heat dissipation fins 103 are installed on the upper part of the heat dissipation box 102. A partition 105 is installed on the upper side of the heat dissipation box 102. The end of the heat absorption tube 101 away from the water pump 104 passes through the middle of the partition 105, and the end of the heat dissipation fin 103 away from the heat dissipation box 102 is installed with multiple cooling fans 106.

[0024] Specifically, the water pump 104 drives the coolant inside the heat sink 102 to circulate inside the heat sink 102 and the heat absorption tube 101, and the heat absorption tube 101 absorbs the temperature generated when the transformer 3 is in operation, and then discharges the coolant after absorbing the heat to the upper part of the partition 105. The partition 105 is close to the top wall of the heat sink 102 to reduce the thickness of the coolant, so that the cooling fan 106 can cool the coolant more quickly through the heat dissipation fins 103, thereby effectively cooling the transformer 3 and improving its working efficiency.

[0025] Working principle:

[0026] When the transformer 3 needs to be disassembled, the lever 202 is moved so that the lever 202 drives the clamping rod 203 to rotate around the middle of the lever 202. Because the lever 202 is pushed to one side by the spring rod 204, the spring rod 204 will fix it, so that the clamping rod 203 can be clamped in the clamping slot 206 or away from the clamping slot 206 by moving the lever 202, so that the transformer 3 can be easily disassembled and installed, and the transformer 3 can be easily repaired. The coolant in the heat sink 102 is driven by the water pump 104 to circulate in the heat sink 102 and the heat absorption tube 101, and the heat absorption tube 101 absorbs the temperature generated when the transformer 3 is in operation, and then the coolant after heat absorption is discharged to the upper part of the partition 105. The distance between the partition 105 and the top wall of the heat sink 102 is close, so that the thickness of the coolant is reduced, so that the heat dissipation fan 106 can cool the coolant more quickly through the heat dissipation fins 103, thereby effectively cooling the transformer 3 and improving its working efficiency.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
