Efficient heating device

Abstract

The invention relates to an efficient heating device which is characterized in that an induction coil is wound on an outer drum, a plurality of hollow inner heating pipes are arranged in the outer drum, two ends of the outer drum are fixedly connected with supporting frames respectively, the inner heating pipes are fixedly connected with the supporting frames, and the induction coil is electrically connected with a power supply. During use, alternating current is input into the induction coil, temperature of the outer drum and the inner heating pipes rises simultaneously, fluid flowing through the inside of the outer drum and the inside and the outside of the inner heating pipes is heated in contact mode directly, a purpose that a fluid section of large-flow fluid is heated with high power through electromagnetic induction is achieved, and a purpose of separating the heated fluid and an outer circuit is achieved. The efficient heating device has the advantages of being high in operation safety and reliability, small in maintaining workload, high in heat efficiency, high in power, small in fluid pressure loss and the like. The efficient heating device can be widely used for heating air, water, crude oil in oil conveying pipelines and chemical reaction kettles and the like.

Description

technical field [0001] The invention relates to heating equipment, which is a high-efficiency heating equipment using electromagnetic induction heating. Background technique [0002] At present, there are electric heaters with electric resistance refueling, electric water heaters with gas heating water, and geothermal or radiators for central heating. The existing electric heating has the disadvantages of small heat dissipation area, and the resistance must have a waterproof and electrical isolation layer, which reduces the energy conversion efficiency. Moreover, the use of resistance heating tubes to heat water in a closed container is also prone to fouling, which seriously causes the entire equipment to be useless. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency heating device capable of applying electromagnetic induction to the fluid section of a...
