Abstract

The utility model provides a portable electric heater which comprises a case box body. An air inlet is formed in a rear plate of the box body. The inner side of the rear plate is provided with a fan. A heater is installed in the box body and electrically connected with a circuit control assembly. The interior of a pipe cavity is a vacuum environment, and low-boiling-point liquid is poured into the pipe cavity. The outer wall of the pipe cavity of a heating pipe is connected with heat dissipating fins. The heater comprises a heating plate and a liquid runner plate. The heating plate comprises a metal base plate. One side of the metal base plate is covered with an electric heating film layer. The liquid runner plate and the heating plate are sealed and fixedly connected to form a heater pipe cavity. According to the scheme, the electric heater is simple in structure, high in heat conversion efficiency and capable of being arranged indoors at will.

Description

Portable electric heater

Technical field

The utility model relates to a kind of electric heater, especially relates to a kind of Portable electric heater, belongs to " the F24D: domestic-heating system or space-heating system, for example central heating system in International Patent Classification (IPC); Domestic hot-water supply system; Its used unit or member " technical field.

Background technology

The commercially available electric heater for warming oneself, adopts electrical heating element as thermal source mostly at present.A kind of electric heater that Chinese patent CN90219715 announces, there is one group of above flange-cooled heating tube inside, and one termination has the heating with heat-insulation layer, also has the fan towards heating tube work in shell.Because the available heat conductance of heating tube own is low, air heat process is long, thereby efficiency is lower, not ideal enough for indoor heating effect.

Chinese patent CN92207684 has announced another rapid electric heater, after being connected, loads onto heating wire form in its one end by the heat pipe of a S-type layout of transverse curvature with fin.Although its thermal efficiency is high, but the arrangement of this single heat pipe requires must have capillary porous material or fibrous material layer in this metal tube, so that condensed fluid flows back to fire end, its complex manufacturing technology, and when run-off the straight, because the condensate liquid in heat pipe can not be got back to heating position fast, so that affect the normal work of heat pipe in using, therefore the inconvenience of the electric heater of this technology is mobile, can only fixedly lay.

Summary of the invention

In view of this, the purpose of this utility model is to provide a kind of simple in structure, and thermal conversion efficiency is high, can be at the indoor Portable electric heater of laying arbitrarily.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of Portable electric heater, comprise container body of outer cover, plate on have air inlet thereafter, blower fan is equipped with in rear plate inner side, heater is installed in casing, heater is electrically connected with circuit controling assembly, in its tube chamber for vacuum environment and be marked with low-boiling point liquid, heating tube tube chamber outer wall connects fin, wherein, described heater comprises heating board, flow channel for liquids plate, this heating board comprises a metallic matrix, this metallic matrix one side is coated with electric membranous layer, flow channel for liquids plate and heating board are sealedly and fixedly connected and are combined into heater lumen.

Preferably, above-mentioned Portable electric heater, wherein: described low-boiling point liquid is sodium acetate.

Again preferably, above-mentioned Portable electric heater, wherein: described bottom half is equipped with humidifier, the nozzle of humidifier is to the air flow outlet of fin.

More preferably, above-mentioned Portable electric heater, wherein: described heating board and flow channel for liquids panel edges position seal welding.

In addition, above-mentioned Portable electric heater, wherein: S-type the arranging of tube chamber on described flow channel for liquids plate.

The utility model technique effect is mainly reflected in: (1) heater adopts electric membranous layer heating, flow channel for liquids plate and the synthetic heater lumen of the fixing soldering group of heating board sealing, tube chamber any part all can be heated, therefore in pipe, need not establish porous material layer, heated by electrothermal film is even in addition, the thermal efficiency is high, and more common conventional Resistant heating is effective; (2) in tube chamber for vacuum environment and be marked with low-boiling point liquid, abandoned employing water or oil and made heat-conducting medium, adopt low-boiling point liquid, preferably sodium acetate can reach the effect of heat radiation heating in a short period of time, and has accumulation of heat effect; (3) bottom half is equipped with humidifier, and the nozzle of humidifier is to the air flow outlet of fin, can be under air dried environment selectable regulating environmental humidity.

Brief description of the drawings

Fig. 1: the utility model structural front view;

Fig. 2: the utility model structure rearview;

Fig. 3: heater structure schematic diagram in the utility model.

In figure, the implication of each Reference numeral is: 1-container body of outer cover, 2-air inlet, 3-blower fan, 4-heater, 40-heating board, 401-metallic matrix, 402-electric membranous layer, 41-flow channel for liquids plate, 410-tube chamber, 5-circuit controling assembly, 6-low-boiling point liquid, 7-fin, 8-humidifier.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, so that technical solution of the present invention is easier to understand and grasp.

As shown in Figure 1, Portable electric heater, comprises container body of outer cover 1, thereafter on plate, have air inlet 2, blower fan 3 is equipped with in rear plate inner side, and humidifier 8 is equipped with in casing 1 bottom, the nozzle of humidifier 8 is to the air flow outlet of fin, for selectable regulating environmental humidity under air dried environment.

Heater 4 is installed in casing 1, heater 4 is electrically connected with circuit controling assembly 5, heater 4 comprises heating board 40, flow channel for liquids plate 41, flow channel for liquids plate 41 and the synthetic heater lumen 410 of the heating board fixing soldering group of 41 edge sealing, tube chamber 410 is S-type arranges for it, increased heating area, heating board 40 comprises a metallic matrix 401, and these metallic matrix 401 1 sides are coated with electric membranous layer 402.In tube chamber 410, be vacuum environment, and be marked with low-boiling point liquid 6, heating tube tube chamber 410 outer walls connect fin 7.

Can find out by above description, circuit controling assembly starts, Electric radiant Heating Film starts to heat to low-boiling point liquid, low-boiling point liquid reaches boiling point, after being further heated, becomes steam flow to tube chamber, and release heat reaches fin by the air heat between fin, because low-boiling point liquid is sealed in tube chamber, although become steam by liquid constantly, then have steam to become liquid, can't be consumed.

Certainly, the above is the exemplary illustration of the utility model typical case application only, by the combination to same or similar technical characterictic and replacement, can form multiple concrete scheme, within these schemes all drop on protection domain of the present utility model.
