Laser Welding Machine Heat Exchanger

Welding machines need heat sinks because the welding process generates a lot of heat, and if this heat is not effectively distributed, it can lead to overheating of the welding machine and even damage to the equipment or reduce the welding effect.

Heat in the welding process comes from two main sources:

The welding arc generated by the current through the welding electrode and the workpiece releases a large amount of heat energy. In this process, the welding current generates resistance, causing the contact area between the welding electrode and the workpiece to heat up, generating a high-temperature welding arc.

The contact resistance between the welding electrode and the workpiece also generates heat. When the welding current passes through the contact surface between the electrode and the workpiece, a certain amount of heat is generated due to the contact resistance.

To maintain the normal operating temperature of the welding machine and to avoid overheating, the heat sink plays a key role. By increasing the contact area between the welding machine and its surroundings, the radiator uses conduction, convection and radiation to disperse heat quickly and keep the temperature of the welding machine within a controlled range.

A heat exchanger is a type of radiator, which usually consists of a set of metal sheets or tubes that conduct heat through a heat-conducting material in contact with the heat source of the welding machine, and then carry the heat away through the flow of air or liquid. This effectively reduces the temperature of the welding machine and ensures its proper operation.

In short, welding machines need heat sinks to effectively distribute the heat generated during the welding process to ensure the normal working temperature of the equipment and avoid problems caused by overheating.
