Description

A kind of electrothermal tube for adding hot liquid
[technical field]
The present invention relates to a kind of electrothermal tube, particularly to the electrothermal tube for adding hot liquid.
[background technology]
Electrothermal tube is mainly used on kettle, water heater, water dispenser etc..The electricity of existing film heating Heat pipe generally comprises earthenware or quartz ampoule, is coated with heating outside earthenware or quartz ampoule Film, heating film is supplied power for by electrode, and when accessing electric current, heating film generates heat, by heat On the liquid that earthenware or quartz ampoule are delivered in pipe, thus in earthenware or quartz ampoule Liquid (such as water etc.) heats such that it is able to heated by liquid faster.Due to earthenware and stone The material characteristic of English pipe is determined, when contacting hot tube wall in the liquid stream of cold conditions flows through pipe The temperature difference is relatively big, and suddenly cold and hot can make earthenware or quartz ampoule explosion, once earthenware or quartz ampoule Explosion, liquid will directly contact with heating film, and what heating film was switched on, thus cause leakage Electricity, uses the people of liquid to have Danger Electric shock risk.
[summary of the invention]
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of security performance is high For adding the electrothermal tube of hot liquid.
In order to solve the problems referred to above, the present invention by the following technical solutions:
A kind of electrothermal tube for adding hot liquid, it is characterised in that: include metal tube, described Metal tube is externally provided with insulating barrier, is provided with heat conduction between described metal tube and described insulating barrier Layer, described insulating barrier is externally provided with heating film, and described heating film is provided with and is linked into by electric current The electrode of described heating film.
A kind of electrothermal tube for adding hot liquid, it is characterised in that: described is exhausted Edge layer is the hollow cylindrical bodies being sleeved on outside described metal tube.

[detailed description of the invention]
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
Embodiment 1, as shown in Figure 1 to Figure 2, a kind of electrothermal tube for adding hot liquid, bag Including metal tube 1, flow through for liquid to be heated in metal tube 1, metal tube 1 can be stainless Steel pipe, aluminum pipe or copper pipe, it is also possible to for other metal tube, its pipe thickness is less than or equal to 2mm, So can ensure that its heat transfer efficiency.Metal tube 1 is externally provided with insulating barrier 2, and insulating barrier 2 is main Playing insulating effect, it can be that earthenware, quartz glass tube or crystallite madreporic canal etc. play insulation The material of effect, insulating barrier 2 can be insulator, and it can be to be sleeved on outside metal tube 1 Hollow cylindrical bodies, is so sleeved on metal tube by the insulating barrier 2 of hollow cylindrical bodies.Metal Being provided with heat-conducting layer 3 between pipe 1 and earthenware 2, heat-conducting layer 3 is heat conduction oil reservoir, and conduction oil is again Claiming heat-transfer oil, canonical name is heat medium oil, can be coated with between metal tube 1 and insulating barrier 2 Cover conduction oil, make metal tube 1 can preferably thermally contact with insulating barrier 2, improve heat transmission Efficiency, insulating barrier 2 is externally provided with heating film 4, can use Patent No. 201220241801.3 In heating film layer material or other heat generating pastes, insulating barrier 2 can use pottery therein Enamel layer.Heating film 4 is provided with the electrode 5 that electric current is linked into heating film 4, and electrode 5 can To be located at heating film 4 two ends, electric current is linked into heating film 4 by electrode 5, makes heating film 4 lead to Heat after electricity, in its heat conduction to metal tube 1, liquid is heated.During installation, can will lead Deep fat is coated in outside metal tube 1 or insulating barrier 2 inwall, is then overlapped ordinatedly by insulating barrier 2 It is contained on metal tube.
Embodiment 2, as shown in Figs. 3-4, the difference with embodiment one is, insulating barrier 2 Different, specifically insulating barrier 2 is the plates being trapped among metal tube 1 outer wall, can be one Sheet or multiple plates are trapped among metal tube 1 outer wall, can use 2,3,4,6 Sheets etc., preferred forms is for using two panels, and metal tube 1 can be hollow circular pipe, two panels Insulating barrier 2 can be to be sticked at the left arc-like sheet 21 of metal tube 1 outer wall and right arc-like sheet 22, Metal tube 1 outer wall is wrapped up by left arc-like sheet 21 and right arc-like sheet 22 substantially.Insulating barrier 2 uses The sheet composition of two semicircular arcs, mainly for insulating in different size ranges of expanding with heat and contract with cold Layer 2 effectively can contact with metal tube 1 outer wall, improves the thermal efficiency, and insulating barrier 2 is not easy Explosion.Owing to insulating barrier 2 is multi-disc, can before and after the conductive electrode of the heating film 4 on so every With series winding, in parallel or connection in series-parallel allotment uses.During installation, can be by respectively at left arc-like sheet 21 and right arc-like sheet 22 internal coat conduction oil, then it is sticked at metal tube 1 outer wall, installs Complete rear left arc-like sheet 21 and metal tube 1 outer wall is wrapped up by right arc-like sheet 22 substantially.
