How to deal with the excess heat of resistance welding equipment?

resistance welding equipment excess heat how to deal with? I believe that many friends are more interested in the following science and technology Xiaobian to explain in detail.

resistance welding equipment connects the welded parts to the electrode, and uses high current to form resistance heat through the contact part. It is widely used in various industries, such as aerospace, electronic components, automobiles and other industries. An indispensable part of technology.

The whole machine covers a three-phase bridge rectifier circuit, filter circuit, full-bridge inverter circuit, intermediate frequency transformer, secondary single-phase full-wave rectifier circuit and its load circuit composed of the main circuit and 32-bit TMS320F28335DSP digital controller, PWM drive circuit, external input circuit and its current sampling circuit composed of the control loop.

The input signal of the DSP is the sampling value and the set value of the welding current. After a series of arithmetic processing, the deviation value of the two is output to make the inverter work.

Therefore, when developing such components, it is not only necessary to ensure its own parameter requirements, but also to consider its heat dissipation and cooling system-water cooling and cooling water channel. Some equipment has poor heat dissipation effect due to poor design of cooling water channel, and may cause damage to spot welding machine and cannot be used. Therefore, cooling system plays an important role in spot welding machine.
