Abstract
The utility model relates to an electric heater which is mainly used for heating in liquids. The utility model is mainly composed of an electric heating tube which has a hollow tubular structure, wherein, one end of the electric heating tube is provided with an electrode. The utility model is characterized in that an inner tube for heat conduction is embedded in a hollow tube of the electric heating tube, wherein, the inner tube is closely contacted with the surface of the inner cavity of the electric heating tube, an outer tube for heat conducting is also sheathed outside the heating tube, and an insulating layer for heat conducting is arranged between the heating tube and the outer tube. The utility model has the advantages of simple structure, and convenient and safe use. The utility model can improve the heat exchanging efficiency and the service life of the electric heating tube.
Description
The utility model is a kind of electric heater that heats in liquid that is mainly used in, and it relates to the raising on structural improvement of existing product and the performance.
A lot of to the mode that it heats at liquid internal, it is modal a kind of adopting electrically heated means.When utilizing electric heating, using electric heating tube is again a kind of device that generally adopts.Electric heating tube in use, its thermal conversion efficiency is a key issue.The present electric heating tube device that uses, be that electric heating tube is encapsulated in the heat conduction copper sheathing of a tape insulation layer, because liquid does not directly contact with electric heating tube, the heat of the outer surface of electric heating tube must just can be delivered in the liquid through insulating barrier and this double-layer structure of copper sheathing and go, and that the transmission of its surface of internal cavity heat just becomes is more difficult, like this, not only caused the reduction of the heat exchanger effectiveness of electric heating tube, but also can be because of the electric heating tube surface of internal cavity owing to the bad temperature that causes of heat radiation is too high, therefore electric heating tube can burst, and has directly influenced the useful life of electric heating tube.So, the key technical problem that the heat exchanger effectiveness of raising electric heating tube is to use this kind device to solve.
The purpose of this utility model designs the electric heater that a kind of new structure is provided at the problems referred to above just, its heating element also is to adopt electric heating tube, but this electric heater is compared with present device, improve the heat exchanger effectiveness of electric heating tube widely, increased the useful life of electric heating tube.
The purpose of this utility model realizes by following measure:
This kind electric heater, it mainly is to be made of an electric heating tube, electric heating tube is a hollow tubular structure, one end has electrode, its structural design features is, the interior pipe of a heat conduction of setting-in in the hollow tube of electric heating tube, and interior pipe closely contacts with the surface of internal cavity of electric heating tube, the also outer tube of suit one heat conduction in the outside of heating tube is provided with the insulating barrier of a heat conduction between the two.In the use, liquid can flow through outer tube-surface and interior pipe at circulation time, directly contacts with its generation, and particularly the heat on interior tube cavity surface can directly be absorbed by liquid, and like this, it is much better that the heat radiation of electric heating tube just becomes, and improved its heat exchanger effectiveness widely.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a kind of structural representation of implementing state of the utility model product
Below with reference to drawings and Examples the utility model is described in further detail:
Shown in accompanying drawing 1, this kind electric heater, it mainly is to be made of an electric heating tube 4, electric heating tube 4 is a hollow tubular structure, be coated with conductive coating on the outer surface of pipe, one end has electrode 2, the structural design features of this electric heater is, the interior pipe 1 of a heat conduction of setting-in in the inner chamber hollow tube of electric heating tube 4, interior pipe 1 closely contacts with the surface of internal cavity of electric heating tube 4, the also outer tube 10 of suit one heat conduction in the outside of heating tube 4, interior pipe 1 and outer tube 10 all adopt copper pipe, between the outer surface of heating tube 4 and the outer tube certain interval is set, size is 2mm, and the insulating barrier 5 of a heat conduction is set in this gap.This insulating barrier 5 adopts the magnesia town to fill and makes, and its bottom 6 and top 3 all adopt sealing device to seal.In addition, the upper end of interior pipe 1 exceeds electric heating tube 4 tops, and the bottom of electric heating tube 4 or concordant with the bottom is hanged down in its lower end.When using this electric heater, put it in the required heated liquid, shown in accompanying drawing 2, liquid is installed in the container 8, electric heater is installed in the top of this container 8 with mounting disc 7, and the top of interior pipe 1 connects the water inlet of container 8, processes an apopore 9 in addition on the top of container 8.Apopore 9 and interior pipe 1 form the circulation of current, and water injects from the top of interior pipe 1, flow out from apopore 9.After the energising, because water can flow through from the interior pipe 1 that is arranged on electric heating tube 4 inner chambers, the heat that surface of internal cavity produces can be absorbed with direct contact of interior pipe effectively by water, like this, the heat that produces of the electric heating tube surface of internal cavity in the existing apparatus problem that is difficult for passing has just obtained solving effectively.And the heat that outer surface produces of electric heater also can be passed by the insulating barrier 5 of heat conduction.By these the two kinds approach that transmit heat, the heat exchanger effectiveness of this kind electric heater has been improved widely, and also just can prolong widely the useful life of electric heating tube.
The utility model compare with existing product have simple in structure, easy to use, safety can Lean on, can improve widely heat exchanger effectiveness and the service life of electrothermal tube.
