High frequency eddy current welding station heating principle

High-frequency eddy current heating is a kind of heating method that converts electrical energy into magnetic energy, so that the heated iron tip (which must be plated with iron) senses magnetic energy to generate heat, that is, the electrical energy is converted into magnetic energy and then converted into thermal energy. In this way, it fundamentally solves the problem of inefficient heating of resistive heating elements such as electric heating films and electric heating coils, and the power saving efficiency is as high as 40% to 80%.

• Heating tube - resistive heating principle

• The principle of resistive heating is to heat the resistance wire through electrical energy, and heat the tip to heat up. The heating method is from outside to inside, and energy is easily dissipated.

High-frequency eddy current heating features:

1, high efficiency and energy saving

Electrical energy - The thermal energy conversion efficiency is over 96%. Under the same conditions, it saves electricity by about 40-80% compared to the resistance heating method.

2, stable operation

High-frequency welding station, micro-electronic control, multi-channel intelligent closed-loop control system and powerful and complete protection function can fully ensure long-term safe and stable operation of the equipment.

3, shorten the warm-up time

Because of the external heating method, the resistance heating method can only conduct heat to the heating body when it touches the inner resistance circle of the heating body, resulting in low heating efficiency and long heating time. The energy-efficient heating method adopts the internal heating method. The internal molecules of the heating body directly induce magnetic energy and generate heat, and the average preheating time is shortened by 2/3 than the resistance wire heating method.

4, intelligent temperature control

Most high-frequency eddy current soldering stations use digital tube or LCD screen to display the current real-time temperature and set temperature. The built-in chip can intelligently control the heating speed and output power, and can be flexibly adjusted according to actual production conditions. It is more power-saving and reliable than manual control. , Facilitate frequent customer refueling production.

5, heating temperature range

The resistance heating method has a low power density and fast heat dissipation to the peripheral space, and is generally difficult to heat above 400°C. The efficient energy-saving method uses internal heat, high power density, and can be heated to temperatures above 600°C.

6, increase the power transformer wide margin

The energy-efficient heating method only uses the installed power of 30-50% of the total power of the original resistance ring, and it can be normally produced, greatly reducing the actual load of the main transmission transformer, greatly increasing the user's power margin, and installing more Production equipment.

7, reduce the partition, modular and quick installation, easy to disassemble

Energy-efficient equipment is customized according to customer's parameters, all adopt modular structure, divided into three modules: chassis, load and temperature control, and according to the required temperature of each part of the heating body for flexible partitioning, through the ring structure to achieve uniform heating, through Switching to achieve partition control, the resistive ring heating method can save partitions and facilitate disassembly.

8, improve the working environment

The energy-efficient heating method adopts the internal heating method. The heat accumulates inside the heating body. There is almost no external heat dissipation. The surface of the device can be touched by the human body. The ambient temperature is reduced from above 100° C. when the original resistance ring is heated to room temperature, which greatly improves the production site. The working conditions will effectively increase the enthusiasm of workers for production and reduce the cost of ventilation and cooling in the factory.

9, reduce maintenance costs

The heating part adopts an annular cable structure, the cable itself does not generate heat, and can withstand high temperatures above 500° C., and its service life is up to 5 years. No maintenance, no maintenance costs during the period.
