Heating unit for electromagnetic heating type instant water heater

Abstract

The invention discloses a heating unit for an electromagnetic heating type instant water heater. A heating portion is connected with a cooling portion through a joint pipeline. The heating portion comprises water flow passages, an integral aluminum casting layer and inductive heating tubes, the water flow passages and the inductive heating tubes are combined through the integral aluminum casting layer by means of aluminum casting, the integral aluminum casting layer is in an integrally hollow cylindrical structure, and the water flow passages surround the inductive heating tubes. The cooling portion comprises a magnetic tube supporting column, a coil support tube, outer end covers, a cooling water inlet nozzle and a cooling water outlet nozzle, the outer end covers are provided with through holes and mounted at two ends of the integral aluminum casting layer, the coil support tube is arranged on the outer end covers through the through holes and connected with the integral aluminum casting layer, the magnetic tube supporting column is mounted in the coil support tube, and two ends of the coil support tube are provided with the cooling water inlet nozzle and the cooling water outlet nozzle.

Description

technical field [0001] The invention relates to an electromagnetic heating unit, in particular to a heating unit of an instant water heater for electromagnetically heating water. Background technique [0002] With the gradual popularization of electromagnetic induction heating water heaters, especially in the field of instant water heaters, compared with conventional electric water heaters, gas water heaters, and solar water heaters, they have the advantages of high energy efficiency, water and electricity isolation, and rapid heating. The heating body of the core component of the water heater often has unreasonable structural design, the complex heat conduction process leads to low heat transfer efficiency, the heat emitted by the coil is completely dependent on the high-power fan blowing out, resulting in loud noise of the whole machine, and the heat is not fully utilized, etc. Inadequacies. Contents of the invention [0003] In view of the above problems, the present i...
