The invention provides a cooling mechanism for a welding machine and belongs to the technical field of machines. In the cooling mechanism for the welding machine, the welding machine comprises a machine shell and a circuit board horizontally and fixedly arranged in the machine shell; the cooling mechanism comprises a cooling draught fan arranged on one side of the circuit board, and a cooling aluminum plate attached to the bottom face of the circuit board; an air outlet of the cooling draught fan is right opposite to the circuit board; two cooling holes formed side by side are formed in the cooling aluminum plate; one cooling hole is located between the cooling draught fan and the other cooling hole; a right-angle-U-shaped gas feeding pipe is arranged outside the machine shell, and is fixedly connected with the machine shell; the two ends of the gas feeding pipe stretch into the machine shell and are inserted and connected into the other ends of the two cooling holes correspondingly; a gas inflow pipe is arranged in the gas feeding pipe, and is located outside the machine shell; one end of the gas inflow pipe is communicated with an inner cavity of the middle portion of the gas feeding pipe; the other end of the gas inflow pipe is fixedly connected with the machine shell; and a gas sucking fan capable of sucking external air into the gas inflow pipe is fixed in the gas inflow pipe. The cooling mechanism for the welding machine has the beneficial effect that a cooling effect can be improved.
Description
technical field [0001] The invention belongs to the technical field of machinery, and relates to an electric welding machine, in particular to a heat dissipation mechanism of the electric welding machine. Background technique [0002] The electric welding machine uses the high-temperature arc generated when the positive and negative poles are short-circuited instantaneously to melt the solder on the electrode and the material to be welded, so as to combine the objects to be contacted. Its structure is very simple, it is a high-power transformer. [0003] Generally, electric welding machines can be divided into two types according to the type of output power supply, one is AC power supply and the other is DC power supply. They use the principle of inductance, the inductance will produce a huge voltage change when it is turned on and off, and use the high-voltage arc generated when the positive and negative poles are short-circuited instantaneously to melt the solder on the w...
