Abstract

The utility model relates to an oil cooling electric welding machine which comprises a shell; an inner chamber of the shell is provided with cooling oil, an iron core and a coil, and the iron core and the coil are submerged in the cooling oil. The iron core is fixed at the lower part of the inner chamber; the input end and the output end of the coil are connected with outer joints of the shell by wires; the upper part of the shell is provided with a pressure relief hole and an oil filling opening; the iron core and the coil are submerged in the cooling oil filled in the shell and cooling fins are arranged on the outer part of the shell; the heat generated in the use of the electric welding machine can be released by the cooling oil, the heat-conductive shell and the cooling fins, thus solving the problem that the overheat results in the abnormal operation of the electric welding machines or even affects the welding quality; the power consumption is little for no fans are required for cooling; compared with other electric welding machines of the same power, less materials are required owing to adopting the cooling oil for cooling and reaching higher current with less coil. The cooling oil electric welding machine has the advantages of reasonable structure, low power consumption and convenient use, and is applicable to various electric welding machines.

Description

Oil cooling is electric welding machine but

[technical field]

The utility model relates to a kind of electric welding machine, relates in particular to a kind of oil that adopts as but electric welding machine of cooling fluid and the oil cooling that can cut down the consumption of energy.

[background technology]

At present, electric welding machine commonly used is long or when using electric current big between in use, electric welding machine generates heat easily, will influence the operate as normal of electric welding machine when overheated and influence welding quality, so some powerful electric welding machines all adopt the blower fan method of cooling to cool off, this cooling means had not only consumed energy, cooling effect but also poor.

[utility model content]

For overcoming the above-mentioned shortcoming of prior art, the utility model provides a kind of oil of using as cooling fluid, and has but electric welding machine of oil cooling rational in infrastructure, that energy consumption is low and easy to use.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of oil cooling is electric welding machine but, comprise housing, in the described housing inner chamber cold oil, iron core and coil are housed, iron core and coil are immersed in the cold oil, this iron core is fixed on the bottom of inner chamber, described coil input end and output link by lead and housing coupling, are provided with relief hole and oil filler on housing top.

Between described joint and housing, insulator is housed.

Outside described housing, fin is housed.

The beneficial effects of the utility model are: iron core and coil are immersed in the housing that cold oil is housed, and fin is housed in outside, the heat that electric welding machine in use produces is distributed by cold oil and heat conduction shell and fin, solved owing to overheated and caused electric welding machine work undesired, influenced the problem of welding quality even; Owing to do not need fan cooled, so little power consumption; Employing cold oil cooling can reach bigger electric current with less coil, with to compare needed material with the electric welding machine of constant power few.Have advantage rational in infrastructure, that energy consumption is low, easy to use, be suitable for various electric welding machines and use.

[description of drawings]

Fig. 1 is the utility model structural representation;

Fig. 2 is a vertical view of the present utility model.

Among the figure: 1-housing, 2-fin, 3-power connection, 4-out splice going splice, 5-relief hole, 6-coil, 7-iron core, 8-cold oil, 9-oil filler.

[embodiment]

Below in conjunction with drawings and Examples the utility model is further specified:

Referring to Fig. 1 and Fig. 2, a kind of oil cooling is electric welding machine but, comprise housing 1, this housing 1 is a heat carrier, iron core 7 and coil 6 are installed in housing 1 inner chamber that is provided with fin 2, and this iron core 7 is fixed on the bottom of housing 1 inner chamber, and the input of coil 6 and output link by lead and housing coupling, at joint and 1 of housing insulator is housed, is provided with relief hole 5 and oil filler 9 on housing 1 top.The heat that electric welding machine when work iron core 7 and coil 6 are produced is delivered on the housing 1 that Heat Conduction Material makes through cold oil 8, and the fin 2 that is located at housing 1 outer surface can be dispersed into heat in the air rapidly, reaches cool effect; Oily temperature rise because of cold oil 8 in the inner chamber produces pressure, the relief hole 5 on housing 1 top can play the effect of pressure release and exhaust, after using certain hour, reduce as cold oil 8 amounts, add cold oil 8 in can be from oil filler 9 toward inner chamber,, can reach bigger electric current with less coil 6 because of adopting cold oil 8 coolings, with compare with the constant power electric welding machine, the material of required use is few.Have characteristics rational in infrastructure, that energy consumption is low and easy to use, be suitable for various electric welding machines and use.

Claims

1, but electric welding machine of a kind of oil cooling, comprise housing, it is characterized in that: in the described housing inner chamber cold oil, iron core and coil are housed, iron core and coil are immersed in the cold oil, this iron core is fixed on the bottom of inner chamber, described coil input end and output link by lead and housing coupling, are provided with relief hole and oil filler on housing top.
