Description

Heat conduction cylinder assembly and heat exchanger

Technical Field

The utility model relates to an electromagnetic induction heating technical field especially relates to a heat conduction section of thick bamboo subassembly and heat exchanger.

Background

The electromagnetic induction heating mode is a heating mode which converts electric energy into magnetic energy to enable a heated steel body (a heat conduction barrel assembly) to induce the magnetic energy to generate heat. In the mode of using electromagnetic induction heating as an electric heat source, the heat-conducting cylinder is made of iron. Because iron has good magnetic conductivity and belongs to a magnetic material, the heat conduction barrel is usually in a barrel shape, the heating coil surrounds the barrel body, and a layer of heat preservation and insulation cotton is arranged between the barrel body and the heating coil. To increase the heat conducting area and to effectively transfer the heat of the tub wall to the inner wall and the central periphery. Generally, iron plate components which are radially shaped from the center of the barrel to the inner wall of the barrel are welded in the barrel of the barrel. The heat conducting cylinder is heated by electromagnetic induction, and the heat of the heat conducting cylinder is uniformly transferred to the inside by the iron plate assembly welded inside the heat conducting cylinder. The heated medium is as follows: the air and the liquid material exchange heat with the heat conducting cylinder through the heat conducting cylinder, so that the heated medium reaches the required temperature.

The traditional heat exchanger is made of iron, so that the equipment investment cost is low. The use cost is high because the corrosion resistance of iron is poor. The corrosion resistance is further reduced in a high temperature environment, and the entire heat exchanger must be replaced within 2 years of normal use. Because the welding form of the heat-conducting fin and the inner wall of the barrel needs to reserve the welding space, each iron plate cannot be too long, and the space between every two iron plates cannot be too small. The welded heat exchanger can not be disassembled for cleaning and maintenance, and the service life of the heat exchanger is further shortened. In addition, the heat exchanger has simple internal structure, small quantity of heat conducting fins and poor heat conducting effect, the temperature of the inner wall of the drum cannot be fully transferred to the center inside the drum, and the problems of unsatisfactory heat conducting effect and slow temperature rise occur.
