Abstract
The utility model discloses a closed-loop water cycle electric heater comprising an electrothermal set consisting of heat exchange vanes. The heat exchange vanes are filled with liquid, and the lower part of the inside of the electrothermal set is provided with an electrothermal pipe. The liquid is covered with a dehydration decompression solution, the density of which is smaller than that of the liquid. The utility model mainly uses the decompression solution to seal the steam produced by the liquid in the chamber of the electric heater, thus preventing the stream from floating to the space of an upper flow layer to form the expansion pressure. The stream pressure is greatly relieved, and the service life of the product is prolonged, so the decompression solution can be widely used in the manufacture of the closed-loop water cycle electric heaters.
Description
Technical field
The utility model relates to a kind of electric heater, particularly a kind of close loop hydrologic cycle electric heater.
Background technology
Present close loop hydrologic cycle electric heater on the market, comprise the warm group of the electricity of forming by several heat-exchanger fins that is interconnected, be perfused with water liquid in the blade, water perfusion amount generally is about the 70-85% of the warm group of electricity volume, the inner below of the warm group of electricity is provided with electrothermal tube, the surface of electrothermal tube and water liquid carry out thermal energy exchange, and by vane heat dissipating to air and reach heating effect, but after water liquid slowly heats, water liquid can begin the gasification of phase transformation gradually, and the steam after the gasification can up waft in the space of supreme fluid layer and form the bulbs of pressure, also can get more and more with the more and more higher steam formation of water liquid temp amount, can produce great vapour pressure after the steam accumulation is a certain amount of, draw from actual experiment: when water liquid was heated to 110 ℃, the pressure of electric heater inner chamber was about 0.16MPa; When water liquid is heated to 130 ℃; the pressure of inner chamber can increase to 0.3MPa; obtain good heating effect and be generally; all can take the high temperature mode of heating; but because the chamber pressure problems of too that the high temperature mode of heating is caused; cause electric warm group expansion blast crisis easily, in the easier service life that seriously causes product, put on people's the research schedule so how effectively to alleviate the vapour pressure of close loop hydrologic cycle electric heater generation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of close loop hydrologic cycle electric heater that effectively alleviates vapour pressure.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of close loop hydrologic cycle electric heater of effective decompression, comprise the warm group of the electricity of forming by heat-exchanger fin, be perfused with water liquid in the blade, water perfusion amount generally is about the 70-85% of the warm group of electricity volume, the inner below of the warm group of electricity is provided with electrothermal tube, is coated with the dried up property decompression liquid of one deck density less than water liquid on the described water liquid;
As improvement of the technical scheme, the viscosity of described decompression liquid is big than water liquid, and boiling point is greater than water liquid, and cladding thickness is 5～15mm.
As further improvement in the technical proposal, described decompression liquid can be oil.
The beneficial effects of the utility model are: this product mainly is to utilize steam envelope dirt that decompression liquid produces electric heater inner chamber water liquid and in the space of the supreme fluid layer that wafts on unlikely and form the bulbs of pressure, vapour pressure is alleviated greatly, prolong the service life of product, thereby can be widely used in the making of close loop hydrologic cycle electric heater.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1; a kind of close loop hydrologic cycle electric heater of effective decompression; comprise the warm group 1 of the electricity of forming by heat-exchanger fin 11; the warm group of electricity 1 can be made into flat or vane type according to actual needs; no matter adopt which kind of form; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model in a word.Be perfused with water liquid 2 in the described blade 11, water perfusion amount generally is about the 70-85% of the warm group of electricity volume, and the warm group of electricity 1 inner below is provided with electrothermal tube 3, is coated with the dried up property of one deck decompression liquid 4 on the described water liquid 2.Under static state, decompression liquid 4 can float on the top of water liquid 2 automatically less than the event of water liquid because of density, because decompression liquid 4 has dried up property and the little characteristic of density, so when the water liquid 2 of below carries out flow circuit, decompression liquid 4 can remain on the top of water liquid 2 forever, and can not flow with water liquid 2 reaches the purpose of envelope dirt steam.
The viscosity of the decompression liquid 4 that this product adopts is big than water liquid, because the decompression liquid 4 that viscosity is big has bigger surface tension, bigger surface tension can effectively block steam and bubble and form vapour pressure from lower to upper, in addition, the cladding thickness of decompression liquid 4 is 5～15mm, boiling point is best more than 180 ℃ greater than water liquid.
Draw from actual experiment: when being coated with one deck density less than the dried up property decompression liquid 4 of water liquid as water liquid 2, when water liquid was heated to 110 ℃, the pressure of electric heater inner chamber was about 0.08MPa; When water liquid was heated to 130 ℃, the pressure of inner chamber just was 0.15MPa.Decompression liquid 4 can adopt hydraulic oil, edible oil, lubricated wet goods when reality is used.
This product mainly is to utilize steam envelope dirt that decompression liquid 4 produces electric heater inner chamber water liquid and in the space of the supreme fluid layer that wafts on unlikely and form the bulbs of pressure, vapour pressure is alleviated greatly, prolong the service life of product, thereby can be widely used in the making of close loop hydrologic cycle electric heater.
