Abstract

An far-infrared electric heating thermotube with a fin is provided, which mainly comprises a heating element, a jacket pipe suited outside the heating element, an enclosed cavity is formed between the heating element and the jacket pipe, the cavity is additionally arranged with a heat conducting medium and is vacuumed, and a spiral fin is enwinded and fixed outside the jacket pipe. The spiral fin and the jacket pipe are coated with the far-infrared coating externally. The utility model simplifies the structure of the enclosed cavity; due to the additional spiral fin and the far-infrared coating outside the jacket pipe, the flow velocity of heat conducting medium is increased, the outer surface area of the thermotube is enlarged, thereby greatly improving the heating efficiency and heating effect of the thermotube.

Description

Band fin infrared ray heating heat pipe

Affiliated technical field

The utility model relates to a kind of heating, specifically refers to a kind of finned infrared ray heating heat pipe.

Background technology

A kind of heat pipe is arranged in the prior art, and its structure is outside heater element, adds the spirality heat transmission fin, puts outer tube again, forms a closed chamber between heater element and outer tube, and add heat-conducting medium in this closed chamber.During use, heat that heater element sends heating closed chamber makes the medium vaporization the chamber in, and follows the helical flow path that the spirality fin forms and flow, and externally heats.Because the spirality fin is unfavorable for heat-conducting medium and flows fast in closed chamber, and the heat-delivery surface of outer tube is less, is unfavorable for external heat transfer, therefore influenced the efficiency of heating surface of heat pipe, and the processing more complicated of this heat pipe, production cost is higher.

Summary of the invention

The purpose of this utility model is with the efficiency of heating surface of effective raising heat pipe, and to simplify its production technology by the improvement to existing heat pipe structure, reduces production costs.

The technical scheme that the utility model adopted is: former spirality fin between heater element and outer tube is changed be located at outside the outer tube, make and form a simple column cavity in the closed chamber, and closed chamber is evacuated, be coated with the last layer far ultrared paint at its outer surface simultaneously.Heat-conducting medium is heated is able to unhinderedly to flow in described closed chamber fast after the vaporization, the outer spirality fin of its outer tube has not only enlarged heat transfer area, and its outside far ultrared paint, has also improved its heating efficiency.

A kind of band fin infrared ray heating heat pipe of the present utility model, mainly comprise a heater element, one is placed in the outer sleeve pipe of heater element, forms a closed chamber between heating and the sleeve pipe, be added with heat-conducting medium in this chamber, it is characterized in that: closed chamber is pumped into vacuum state; Outside sleeve pipe, twine and be fixedly connected with the spirality fin.

Outside described spirality fin and sleeve pipe, scribble the far infrared coating.

The beneficial effects of the utility model are: simplified the structure of closed chamber, the flow rate of heat-conducting medium is increased, thereby improved the heat exchange efficiency of heat pipe; It is long-pending to have strengthened heat pipe outer surface, has improved to add thermal effect; The far ultrared paint of heater appearance has improved heating efficiency; Owing to simplified product structure, therefore simplify production technology simultaneously, reduced production cost.

Description of drawings

Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.

Fig. 1 is the organigram of infrared ray heating heat pipe of the present utility model.

Among the figure: 1 binding post, 2 heater elements, 3 sleeve pipes, 4 closed chamber, 5 spirality fins, 6 annular rings, 7 far infrared coatings, 8 heat-conducting mediums.

The specific embodiment

Among Fig. 1, heater element 2 one ends are provided with binding post 1, establish an annular ring 6 on its cylinder, the openend of sleeve pipe 3 and this annular ring soldering and sealing, the other end sealing of sleeve pipe 3 makes and forms closed chamber 4 between heater element 2 and the sleeve pipe 3, adds the heat-conducting medium 8 and the state that is evacuated in this closed chamber 4, the sleeve pipe 3 outer spirality fins 5 that are welded with scribble the far infrared coating outside spirality fin 5 and sleeve pipe 3.

Described spirality fin 5 can be the monolithic winding type or biplate spiral.

During use, binding post 1 is connected with power supply, after heater element 2 energisings, to closed chamber 4 heating, make heat-conducting medium 8 vaporizations in this chamber, and in this closed chamber 4, reflux, heat passes to around its outside spirality fin 5 by sleeve pipe 3, because sleeve pipe 3 scribbles far ultrared paint with the surface of fin 5, so the electromagnetic wavelength of its emission is based on far infrared, and its heating efficiency is higher than the heat pipe of no far ultrared paint.

Claims

1. be with fin infrared ray heating heat pipe for one kind, mainly comprise a heater element, one is placed in the outer sleeve pipe of heater element, form a closed chamber between heater element and the sleeve pipe, be added with heat-conducting medium in this closed chamber, it is characterized in that described closed chamber is pumped into vacuum state, outside described sleeve pipe, be provided with the spirality fin.

2. band fin infrared ray heating heat pipe according to claim 1 is characterized in that scribbling the far infrared coating outside described spirality fin and sleeve pipe.

3. band fin infrared ray heating heat pipe according to claim 1 and 2 is characterized in that described spirality fin twines and is fixedly connected on the described sleeve pipe, and this fin is that monolithic winding type or biplate winding type are wound on the described sleeve pipe.
