Abstract

A fluid heating device comprises a magnetic core 101, a primary coil 102 wound around the magnetic core, and a secondary coil 104 wound around the magnetic core. The secondary coil has a fluid channel passing through it so that when a varying electrical voltage is applied to the primary coil, a large current is induced in the secondary coil causing heating of the coil, and therefore heating of the fluid passing therethrough. A temperature sensor 108 detects the fluid temperature and can control a power control device 103 for adjusting input power from the primary winding 102. <IMAGE>

SUMMARY OF THE INVENTION The present invention relates to a fluid heating device formed by a secondary winding with fluid line close loop, comprising an interconnected metal core, a primary winding to get input AC or pulse electric energy, and a loop made of conductive materials and permitted for conductive or nonconductive to pass thereof, and heating the fluid therein with thermal energy produced from low-voltage major current, and characterized as follows: 1. The secondary winding having an inlet to allow fluid to flow in and an outlet to allow it to flow out thereof, said inlet and outlet appearing a non-interference close structure to insure fluid flowing in said inlet continuously thereof, and thus to form a heating loop during the transit of fluid flowing out.

2. The secondary winding itself appearing a close loop consisted in conductors being connected together or welded or one-piece-made to encase a magnetic circuit to form a current loop so as to be engaged in high efficiency and direct heating up the internal fluid with thermal energy produced by the current.

A comparison to various traditional heating means shown below: (1) Comparing to the type of heating indirectly by means of resistance wire, the present invention has the advantages -- high efficiency, long life span, low voltage major current, high safety.

(2) Comparing to magnetic-inductive heating for non circular object being heated, such as electric induction furnance heating water, the interconnection of the latter is lower due to incomplete magnetic circuit.

With above-mentioned characteristics, we can apply the present invention for heating gas or liquid type fluid passing through said loop, such as chemical fluid heating device for industrial purpose, or household water heater, flask or other kind of fluid heating; further, we may set up a temperature sensor at the portion of heating source for manipulating a power control device between the primary winding and power supply so as to promote safety and heating function as well as to overcome the defects of existing electric heater devices.
