Detailed Description
The following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
Example 1:
as shown in fig. 1-2, an electric welding machine comprises an electric welding machine body, wherein the electric welding machine body is of a hollow cubic structure, a front panel is provided with a front air outlet 2 and a control panel, a back panel is provided with an air inlet 8, and two sides of the back panel are provided with side air outlets 4; a control circuit connected with a control panel is integrated in the control panel 1, and the control panel 1 is positioned on one side of the electric welding machine body; the radiator 7 connected with the control panel 1 is fixed at the rear part of the electric welding machine body by the radiator support 5, the heat dissipation working surface of the radiator 7 is over against the air inlet 8, the main transformer 6 and the capacitor bank 2 are arranged in parallel, and the two are positioned in the middle of the electric welding machine body.
Under cooling fan's effect, the air that air intake 8 produced passes through radiator 7 earlier, flows through main transformer 6 and electric capacity group 2 again, finally flows out by preceding air outlet 3 and side air outlet 4 and takes away the heat, and can not flow through the control panel, ensures that the surface of control panel 1 can not accumulate dust and steam, and then the life-span of extension electric welding.
The heat generated during the operation of the electric welding machine is mainly from the main transformer 6 and the capacitor bank 2, and the heat is also partly from the control board 1, and the heat radiator 7 of the control board 1 can ensure the stable operation temperature.
