An electromagnetic heating device with water cooling

Abstract

The invention discloses an electromagnetic heating device with a water cooling function. The electromagnetic heating device comprises an electromagnetic coil and a coil support. The electromagnetic coil is evenly wound on the outer surface of the coil support, the surface where the electromagnetic coil and the coil support are in contact with each other is evenly wrapped with a layer of heat conduction silica gel insulation sheet, and a magnetic tube is further arranged in the coil support. The magnetic tube is fixedly connected by a magnetic tube supporting pillar arranged on the coil support, the two ends of the magnetic tube supporting pillar are each provided with a special water hole, and the two ends of the magnetic tube supporting pillar are further in small clearance fit connection with a water inlet nozzle and a water outlet nozzle. The water inlet nozzle and the water outlet nozzle are connected with the coil support through threads. According to the electromagnetic heating device with the water cooling function, cooling water channels need to be formed in the water inlet nozzle and the water outlet nozzle, the water holes are formed in the magnetic tube supporting pillar, the purpose is that cooling water led in by the water inlet nozzle can be split, the inner surface and the outer surface of the electromagnetic coil and the magnetic tube or a magnetic ring can be cooled at the same time, and the electromagnetic coil and the magnetic tube can both maintain a low temperature.

Description

technical field [0001] The invention relates to a heating coil device, in particular to an electromagnetic heating device with water cooling. Background technique [0002] The principle of electromagnetic heating is to generate an alternating magnetic field through the components of the electronic circuit board. When a ferrous container is placed on it, the surface of the container cuts the alternating magnetic force lines and generates an alternating current (ie eddy current) at the metal part of the bottom of the container. Make the iron atoms at the bottom of the container move at high speed and irregularly, and the atoms collide and rub against each other to generate heat energy; thus, the effect of heating the object is achieved. At present, the heat dissipation problem of the electromagnetic heating coil disk of any electromagnetic product has always been a very important problem. The heat dissipation method with better heat dissipation performance has always been the ...

Problems solved by technology

At present, the heat dissipation problem of the electromagnetic heating coil disk of any electromagnetic product has always been a very important problem. The heat dissipation method with better heat dissipation performance has always been the need of the market, especially when the electromagnetic heating coil disk is in a position that is unfavorable for heat dissipation (such as placing When inside the tube), the heat dissipation problem is more serious, and sometimes the product structure has to be changed, which has a very adverse effect on product development, so there is an urgent need for a better heat dissipation method
