Description
Technical field
It the utility model is related to a kind of coal and change electric heating apparatus, be specifically a kind of two-pass highly-efficient rate electromagnetic induction heating
Device.
Background technology
At present, traditional heating be essentially all using coal-burning boiler, it is environmentally friendly but with the getting worse of pollution that caused by coal burning
It is required that more and more stringenter, the cry that coal changes electricity is also just higher and higher, has gone out various coals therewith and has changed electric installation, its
In, having a kind of coal of electromagnetic induction heater to change, electric installation using effect is preferable, and kind is also more, but its existing maximum
The shortcomings that be exactly that the thermal efficiency is low.
The content of the invention
The purpose of this utility model is to solve the problems, such as that the existing electromagnetic induction heater thermal efficiency is low, and is provided a kind of
Two-pass highly-efficient rate electromagnetic induction heater.
The utility model is achieved by the following technical solution：
A kind of two-pass highly-efficient rate electromagnetic induction heater, including insulation tube and metal tube calandria, the top of insulation tube
And bottom lock, electromagnetic induction coil is wound with along its axial direction on the outer wall of insulation tube；Metal tube calandria is set in insulation tube
Interior, the two is coaxially disposed；The bottom nozzle of metal tube calandria is sealingly fastened in the tube bottom of insulation tube, metal tube calandria
Gap sky is left between top nozzle and the tube top of insulation tube and between the outer wall of metal tube calandria and the inner wall of insulation tube
Between；The tube bottom of insulation tube is equipped with water inlet and water outlet, wherein, between water inlet and metal tube calandria and insulation tube between
Gap space communicates, and water outlet is communicated with space in the pipe of metal tube calandria.
The course of work of the utility model heater is：Electromagnetic induction coil heats metal tube calandria, water at low temperature from
Water inlet enters, in the clearance space for proceeding to metal tube calandria outer wall before this between the inside pipe wall that insulate, by metal tube plus
Hot external wall absorbs heat, is then entered again by the clearance space between metal tube calandria top nozzle and insulation tube tube top
To in the pipe of metal tube calandria in space, by the double absorption heat of metal tube calandria inner wall, finally from water outlet stream
Go out, it is achieved thereby that double-flow endothermic process, is greatly improved the thermal efficiency.
As preferable technical solution, the electromagnetic induction coil is connected with frequency conversion control unit.Frequency conversion control unit
50HZ frequency alternating currents are changed to 20KHZ--40KHZ, pass through electromagnetic induction by also known as electromagnetic heating controller, frequency conversion control unit
Coil produces high-frequency alternating magnetic field, and metal tube calandria cutting alternating magnetic field produces alternating current and is vortexed, and vortex flow makes metal tube
The iron molecule high speed random motion of calandria, molecule, which collides with each other, produces thermal energy, is circulated using its caused heat
Water, realizes heating.
It is the utility model heater design science, of simple structure and low cost, easy to use, it is provided with double-flow heat absorption
Process, is greatly improved heat transfer efficiency.The utility model product since launch, has been highly commended by customers deeply through development and production.
