Abstract

The utility model discloses an external heating electromagnetic heat exchanger; the heating surface of a traditional electromagnetic heat exchanger is generally limited at one bottom surface or one side surface of a heating body, and a coil and iron oxygen bodies are flatly paved at the bottom part or one side surface of the heating body, when heating, the heating of the product to be heated can only be carried out from the bottom surface or the side surface, so the thermal efficiency is low and the shape is single; the heating body of the utility model is arranged at the outmost layer, the cylindrical coil is arranged in the periphery of the inner wall of the heating body, and two blocks or more strip-shaped iron oxygen bodies are affixed on the inner wall of the coil; as the heating body is arranged at the outmost layer and the heating surface can be directly contacted with the liquid to be heated, the thermal efficiency is high; the coil is cylindrically enclosed at the inner wall of the heating body, the high frequency current can generate a magnetic field by a coil circuit, the vortex can be generated on the heating body to heat the heating body, the heating area is increased, the heating is fast, and the shape of the whole product can be designed into a plurality of shapes; the utility model can be widely applicable to various large and medium-sized water heaters.

Description

External heating type electromagnetism heat exchanger

Technical field

The utility model relates to a kind of electromagnetism heat exchanger, particularly a kind of external heating type electromagnetism heat exchanger.

Background technology

Electromagnetism heat exchanger product in the past is because limitation of design, the heating area of product is little, the heating face of such heat exchanger generally is confined to a bottom surface or side of heater, coil and ferrite also all are bottom or sides that is tiled in heater, can only be during heating from the bottom surface or the side give and need heated products to heat, the heat efficiency is low; In addition, also have a kind of internal heat generation formula electromagnetism heat exchanger and since heater be confined to peripheral around coil within, volume has certain limit, can not apply to large and medium-sized heater.

Summary of the invention

At the problems referred to above, the utility model provides the external heating type electromagnetism that a kind of face that generates heat is big, the heat efficiency is high heat exchanger.

The technical scheme that its technical problem that solves the utility model adopts is:

External heating type electromagnetism heat exchanger comprises heater, coil, ferrite and insulating material, and heater is installed in outermost layer, and the periphery of inner wall of heater by the built-in coil of one deck insulating material, is posted two or above ferrite on the inwall of coil.

The beneficial effects of the utility model are: because heater is installed in outermost layer, heating face directly contacts with needing heated liquid, heat efficiency height, coil is trapped among the periphery of inner wall of heater with tubular, high-frequency current produces magnetic field by wire loop, produces eddy current and make the heater heating on heater, and heating area increases, heating is fast, and entire product can be installed in various large, medium and small type heaters inside.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Embodiment

With reference to Fig. 1, external heating type electromagnetism heat exchanger, comprise heater 1, coil 2, ferrite 3 and insulating material 4, heater 1 is wrapped in the outermost layer of whole heat exchanger, the periphery of inner wall of heater 1, by one deck insulating material 4 built-in coils 2, post two or above ferrite 3 on the inwall of coil 2.Because heater 1 is installed in outermost layer, can be directly installed on various big after entire product is packaged, in, in the small-sized heater, heating face directly contacts with needing heated liquid, it is fast to conduct heat, heat efficiency height, high-frequency current produces magnetic field by coil 2 loops, on heater 1, produce eddy current and make heater 1 heating, because coil 2 is trapped among the periphery of inner wall of heater by one deck insulating material 4, and ferrite 3 is attached to bar shape on the inwall of coil 2, and whole field circuit is shielded between coil 2 and the heater 1, and heating area increases, heating is fast, makes the heat efficiency of whole heat exchanger improve.

With reference to Fig. 2, be the convenience of producing and installing, the shape of coil 2 of the present utility model is preferably designed as the garden tubular, because the coil 2 of garden tubular not only coiling is convenient, and the magnetic field that produces, energising back can be centered around fully heater 1 around, it is next to make heater 1 can send maximum heat in the shortest time, thereby improves the heat efficiency, the minimizing energy consumption of product from another aspect.

With reference to Fig. 1, Fig. 2, because the novel coil 2 of this reality is designed to the garden tubular, height is on the point of electric current and is produced magnetic field by coil 2 loops, the effect of ferrite 3 mainly is the shielding action of the magnetize line of force, in order to play best shielding action, the shape of ferrite 3 of the present utility model is preferably bar shaped, length just can be attached to all magnetic lines of force of coil 2 external shields, coil 2 sizes are big more, coil 2 number of turns are many more, in order to play shielding action completely, the quantity of ferrite 3 also should increase along with the increase of coil 2 sizes.
