[0002] An electric welder is an electrical device used for welding metal materials.

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] When the utility model is performing cooling work of the welding machine, the high-power transformer 7 is powered on and started, and the high-power transformer 7 converts the high-voltage, low-current power supply into a low-voltage, high-current power supply and transmits it to the welding machine power supply control box 2 for welding transformation and power supply work. The high-power transformer 7 generates heat during the transformation process, and the high-power transformer 7 transfers the heat to the temperature difference power generation sheet 18. The heat of the bonding surface of the temperature difference power generation sheet 18 and the high-power transformer 7 increases, and the bonding surface of the temperature difference power generation sheet 18 and the high-power transformer 7 forms a temperature difference with respect to the bonding surface of the temperature difference power generation sheet 18 and the heat sink 19. The temperature difference power generation sheet 18 converts heat energy into electrical energy by using the thermoelectric effect, and the temperature difference power generation sheet 18 transmits the generated electrical energy to the fan machine 11, so that the motor of the fan machine 11 drives the fan of the fan machine 11 to rotate, and the fan machine 11 inhales the cold air outside the welding machine from the air inlet plate 4 and the ventilation pad 12. At this time, the ventilation pad 12 uses polyurethane The air filtering characteristics of the filter sponge block dust from the outside and prevent dust from being sucked into the welding machine. The fan 11 blows air to the three groups of heat sinks 19. The fan 11 cooperates with the heat sink 19 to cool the upper side of the high-power transformer 7 and the outer side of the temperature difference power generation sheet 18. Then the airflow discharges the remaining heat dispersed in the air from the long through grooves on the left and right sides of the carrier casing 3, completing the cooling of the welding machine. When it is necessary to inspect and repair the high-power transformer 7 in the welding machine, the rotating handle 5 is manually turned, and the rotating handle 5 drives the threaded rod 8 to rotate. Since the threads on the outer side of the threaded rod 8 are engaged with the threaded through holes of the fixed support plate 10, the threaded rod 8 drives the bottom plate 15 carrying the high-power transformer 7 to be lifted upward and extended out from the carrier casing 3 through the threaded through holes of the fixed support plate 10, completing the rapid separation and disassembly of the welding machine casing, which is convenient for the inspection and maintenance of the high-power transformer 7.
[0025] In the disclosed embodiment, a through hole is provided on the upper side surface of the top plate 17, the top end of the threaded rod 8 is rotatably connected in the through hole of the top plate 17, a square through groove is provided on the upper side surface of the top plate 17, the fan 11 is connected in the square through groove of the top plate 17 by bolts, the square through groove of the top plate 17 is opposite to the heat sink 19 on the upper side surface of the high-power transformer 7, the fan 11 can blow the external cold air flow directly onto the heat sink 19 to cool the high-power transformer 7.
[0026] In the disclosed embodiment, a threaded through hole structure that passes through the fixed support plate 10 from top to bottom is provided at the center portion of the fixed support plate 10, and the threads on the outer side of the threaded rod 8 are engaged and connected in the threaded through hole of the fixed support plate 10. When the handle 5 is turned to drive the threaded rod 8 to rotate in the threaded through hole of the fixed support plate 10, the threaded rod 8 can drive the top plate 17 and the bottom plate 15 to be lifted vertically up and down, thereby completing the rapid opening of the welding machine casing.
[0027] In the disclosed embodiment, the ventilation pad 12 is made of polyurethane filter sponge material, and the high airflow permeability of the polyurethane filter sponge is utilized to ensure that air can circulate inside and outside the welding casing, thereby preventing external dust from being sucked into the welding casing by the fan 11 and gathering inside the welding casing, thereby avoiding dust contamination that may cause a short circuit and fire in the high-power transformer 7.
[0028] In the disclosed embodiment, the carrier casing 3 is a rectangular box structure with openings on the front side and the upper side. The left side and the right side of the carrier casing 3 are provided with twelve groups of long through grooves. The carrier casing 3 cooperates with the fan 11 in the square through groove of the top plate 17 to form an air flow passage to accelerate the heat discharge of the high-power transformer 7.
[0029] In the disclosed embodiment, there are three groups of heat sinks 19, each group of heat sinks 19 is made of copper metal, and a large number of heat sinks are densely distributed on the heat sinks 19. The heat sinks of the heat sinks 19 perform convection heat exchange with the air blown by the fan 11, transferring heat from the heat sinks to the air, thereby reducing the temperature of the heat source of the high-power transformer 7.
[0030] In the disclosed embodiment, there are two groups of thermoelectric power generation sheets 18, which are tightly connected to the left and right sides of the high-power transformer 7 by bolts, and are connected to the fan 11 by wires. The temperature difference between the contact surface of the thermoelectric power generation sheet 18 with the high-power transformer 7 and the non-contact surface outside the thermoelectric power generation sheet 18 is utilized to generate electricity, convert the heat energy of the high-power transformer 7 into electrical energy, and drive the fan 11 to rotate.
[0031] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The power control box 2, high-power transformer 7, fan 11, and temperature difference power generation sheet 18 used above are all common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.
