Abstract
The utility model relates to a heating device of a heat supply system. The heating device of the heat supply system is characterized by comprising a heat conduction device and a temperature control circuit, wherein the heat conduction device is cylindrical and composed of a cylinder body, an electric heating cable and an asbestos sleeve, the electric heating cable is formed by connection of a hot wire and a cold wire through a cold-wire hot-wire junction box, the cold-wire hot-wire junction box is molded on the cylinder body, the cold wire and the hot wire are firmly welded in the cold-wire hot-wire junction box, resinous insulating materials are poured in the box and sealed, the hot wire winds the inner wall of the cylinder body and fixes the multi-circle electric heating cable and winds the outer wall of the cylinder body to wrap the asbestos sleeve, a water outlet and a water return opening are formed in the cylinder body, and one end of the cold wire extends out of the cold wire hot wire junction box to be connected with a power source. The heating device of the heat supply system with an encirclement-type conduction heating method has the advantages of being high in insulating property, without electromagnetic interference, good in flexibility of electric heating cable, light in weight, long in service life and wide in application range.
Description
Technical field
The utility model relates to electric calorifie installation, particularly a kind of heater of heating system.
Background technology
At present, the heater of heating system has various ways, and the Electric heating of electric heating apparatus is wherein a kind of, and electrical heating is comparatively general with resistance wire/quartz heating.But resistance wire/quartz heating, its thermal efficiency is very low, and also has the shortcoming of a lot of other sides.This mode of heating, mainly be to be abutted against to touch to conduct transferring heat energy, various heating plates, the circle made with resistance wire only have a face to touch the position that needs heat supply, although a big chunk thermal dissipation is arranged in air, but the influence of temperature change to environment is little, if electrothermal method and water warm combination can be improved area of heat-supply service and efficient greatly.
How by electrothermal method and device structure are improved, just can overcome the defective of prior art, become the problem that those skilled in the art will study and solve.
Summary of the invention
In view of the prior art above shortcomings, the utility model provides a kind of design of heater of heating system, heater structurally adopts circulating type conduction mode of heating, calandria adopts the heating cable that is tightly connected,, realize homogeneous heating, overcome heat dissipation and the unbalanced defective of water temperature around the water in the heated container of contact by Heat Conduction Material, the hot water of constant temperature is provided for water circulation pipe, with electrothermal method and water warm combination, improve the efficiency of heating surface.
The technical scheme that the utility model is taked for achieving the above object is: a kind of heater of heating system, it is characterized in that, consisted of by heat transfer device and temperature-control circuit, heat transfer device is cylindrical tubular, heat transfer device is made of cylindrical shell, heating cable and asbestos cover, and heating cable is tightly connected by cold and hot line terminal box by hot line and cold line and forms; Cold and hot line terminal box is injection-moulded on the cylindrical shell; Cold line and hot line in cold and hot line terminal box firm welding and in box the sealing resin insulating materials;
Hot line coats the asbestos cover around the fixing multi-turn shape heating cable of the inwall of cylindrical shell around cylinder body outer wall; Cylindrical shell is provided with delivery port and water return outlet;
Cold line is drawn termination power in cold and hot line terminal box;
Temperature-control circuit comprises single-chip microcomputer and temperature sensor, and temperature sensor is installed in the cylindrical shell, and the signal end of temperature sensor connects single-chip microcomputer.
The cavity cuboid that cold and hot line junction box structure is makrolon material.
Advantage of the present utility model: structurally adopt circulating type conduction mode of heating, calandria adopts the heating cable that is tightly connected, and, realizes homogeneous heating, overcomes heat dissipation and the unbalanced defective of water temperature around the heated container of contact by Heat Conduction Material.Its insulating properties are high, and heating cable has the loop of one's own, without electromagnetic interference; The heating cable pliability is good, lightweight, long service life and applied widely.
