DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Embodiment 1

[0026] Combination Figure 1-5 As shown, this embodiment provides an arc welding machine transformer, including: a main body module 100 and a heat dissipation module 200.

[0027] The main body module 100 includes an iron core 110 and a winding 120 symmetrically sleeved on the iron core 110 . The iron core 110 and the winding 120 cooperate to form the main body of the arc welding machine transformer.

[0028] The heat dissipation module 200 is used to dissipate heat for the iron core 110 and the winding 120, and includes a top shell 210 fixed on the top of the iron core 110, a first water inlet pipe 220 installed on one side of the top shell 210 and connected to the inner cavity of the top shell 210, a bottom shell 250 fixed on the bottom end of the iron core 110, a first water outlet pipe 260 installed on one side of the bottom shell 250 and connected to the bottom shell 250, a heat pipe 230 arranged in an array through the iron core 110 and connected to the top shell 210 at one end and connected to the bottom shell 250 at the other end, a baffle 240 fixed in an array on the inner wall of the heat pipe 230, a heat conducting ring 270 sleeved on the winding 120, a second water inlet pipe 280 installed on the heat conducting pipe 230, and a second water outlet pipe 290 installed on the heat conducting ring 270.

[0029] The top shell 210 is used to deliver cooling water into the heat pipe 230. The first water inlet pipe 220 is connected to the top shell 210 and is used to deliver cooling water into the inner cavity of the top shell 210. The bottom shell 250 is used to deliver the cooling water discharged from the heat pipe 230 that takes away heat into the first water outlet pipe 260. The first water outlet pipe 260 is used to discharge the cooling water.

[0030] The top of the iron core 110 is provided with through holes 111 in an array that penetrate the iron core 110. The heat pipe 230 is embedded in the through hole 111, and insulating paper is provided between the heat pipe 230 and the inner wall of the through hole 111 to prevent the heat pipe 230 from affecting the operation of the iron core 110. The heat pipe 230 is made of a heat-conducting material and is used to absorb the heat generated when the iron core 110 is working. When the cooling water flows through, the heat is exchanged with the cooling water, so that the heat on the heat pipe 230 is taken away by the cooling water, that is, the heat of the iron core 110 is dissipated.

[0031] There is an opening between the baffle 240 and the inner wall of the heat pipe 230, and adjacent baffles 240 are arranged symmetrically with respect to the center, forming an S-shaped flow channel in the inner cavity of the heat pipe 230, extending the flow path of the cooling water in the heat pipe 230, that is, extending the time for the cooling water to pass through the heat pipe 230, so that the cooling water can fully exchange heat with the heat pipe 230, absorb and take away more heat, and improve the heat dissipation efficiency.

[0032] The heat-conducting ring 270 is included on the outside of the winding 120 and is made of a heat-conducting material for absorbing the heat generated when the winding 120 is working. A spiral flow channel 271 is provided inside the heat-conducting ring 270 for cooling water to flow therein, exchange heat with the heat-conducting ring 270, take away the heat on the heat-conducting ring 270, and then dissipate the heat of the winding 120. In addition, insulating paper is provided between the heat-conducting ring 270 and the winding 120 to prevent the heat-conducting ring 270 from affecting the operation of the winding 120.

[0033] The second water inlet pipe 280 is connected to one end of the spiral flow channel 271 for delivering cooling water into the spiral flow channel 271 , and the second water outlet pipe 290 is connected to the other end of the spiral flow channel 271 for discharging the cooling water after absorbing heat.

[0034] In addition, a plurality of heat dissipation fins 272 are arranged in an array on both sides of the heat conductive ring 270 to increase the contact area between the heat conductive ring 270 and the air, so that the air can take away the heat on the heat conductive ring 270 when passing through, thereby increasing the heat dissipation efficiency of the heat conductive ring 270.

[0035] The working principle and use process of the utility model are as follows: when the transformer is working, the heat on the iron core 110 is transferred to the heat conducting pipe 230. After the cooling water enters the top shell 210 through the first water inlet pipe 220, it enters the heat conducting pipe 230 through the top shell 210. When the cooling water flows in the heat conducting pipe 230, it exchanges heat with the heat conducting pipe 230. At the same time, the S-shaped flow channel formed by the baffle 240 prolongs the time for the cooling water to pass through the heat conducting pipe 230, thereby taking away the heat on the heat conducting pipe 230 and dissipating it through the bottom shell 250 and the first water outlet pipe 260, and dissipating the heat of the iron core 110 by water cooling. In addition, the heat on the winding 120 is transferred to the heat conducting ring 270, and the cooling water is sent into the spiral flow channel 271 through the second water inlet pipe 280, and flows in the spiral flow channel 271, and exchanges heat with the heat conducting pipe 230, thereby taking away the heat on the heat conducting ring 270, that is, dissipating the heat of the winding 120.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
