Abstract
The utility model discloses an electric heater with superconductive media, which is provided with a casing (1) in which superconductive media (2) and an electric heating element (3) are arranged. The casing (1) is connected with a cavity plate (4), and a through hole (5) is arranged between the casing (1) and the cavity plate (4). All superconductive media have smaller thermal expansion coefficient, and the superconductive media are heated by the electric heating element, and then the heated superconductive media enter the cavity plate through the through hole after expanded to directly emit the heat externally. The cavity plate self can be used as a floor and a window sill which save space and the radiation effect is good. The cavity plate can also be used as a door frame, particularly a door frame of a refrigerator, therefore the phenomenon that the door of the refrigerator can not be opened at low temperature can be avoided.
Description
Technical field:
The utility model relates to a kind of electric heater unit, especially a kind of superconductive medium electric heater that can be applicable to occasions such as floor, windowsill, doorframe experimental bench.
Background technology:
At present, the heating system in residential building, public place has following two kinds basically: a kind of is that this kind mode thermal conversion efficiency is low with coal, combustion gas or the fuel oil mode to the water heating, and the fuel combustion process environmental pollution is serious, fuel used all is natural resources, and its storage capacity is limited; Also having a kind of is exactly for overcoming the electric heating mode that first kind of deficiency that mode had advocated, air-conditioning, Electric radiant Heating Film, electric heating water heater, electric heater etc. are arranged, but all exist problems such as thermal conversion efficiency is low, power consumption is big, product operating cost is very high, and the user is difficult to accept.Electric heater as is well known, its structure all is that water, wet goods heat medium are housed in housing, with electrical heating elements medium is heated, by a plurality of solid fin heat radiations of joining with housing.Because the space is limited in the housing, the thermal coefficient of expansion of water, oil is bigger in addition, so heating-up temperature must remain under the medium boiling temperature, this needs could guarantee to reach heating temperature often to its heating that it is bigger to consume energy.In addition, the conventional electric heating device all exists the big problem that takes up room, and can't be applied to positions such as doorframe.
Summary of the invention:
The utility model be for solve the existing in prior technology big energy-consuming, the problem such as big that takes up room, provide a kind of energy-conservation and take up room the superconductive medium electric heater little.
Technical solution of the present utility model is: a kind of superconductive medium electric heater, housing 1 is arranged, and superconductive medium 2 and electrical heating elements 3 are arranged in the housing 1, be connected to cavity plate 4 with described housing 1, between housing 1 and the cavity plate 4 through hole 5 is arranged.
Described electrical heating elements is an electric heating tube.
Described through hole 5 is at least three.
The used superconductive medium thermal coefficient of expansion of the utility model is less, by electrical heating elements superconductive medium is heated, and the superconductive medium that is heated enters in the cavity plate by through hole after expanding, directly externally heat radiation.Cavity plate itself can be used as floor, windowsill, saves space, good heat dissipation effect; Also can be with it as doorframe, especially the freezer doorframe avoids occurring at low temperatures the phenomenon that cold-storage door can't be opened.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: in metal housing 1, fill the fast superconductive medium of making by potassium bichromate, potassium sulfate 2 of heat-transfer rate, and will place in the housing 1 with the electrical heating elements 3 (electric heating tube, electric heating film) that power supply joins.Also be connected to cavity plate 4 with housing 1, the vestibule plate 4 material of handy good heat conduction effect is made, and as metal etc., through hole 5 is arranged between housing 1 and the cavity plate 4, and through hole 5 can be 1,2,3 even more.Whole device can also be provided with power supply indicator, temperature-control circuit etc.
The course of work:
After electrical heating elements connected power supply, electrical heating elements heated superconductive medium, superconductive medium be heated to expand in the back and by through hole to cavity plate and outwards heat radiation.Because it is little that potassium bichromate, potassium sulfate such as make at superconductive medium thermal coefficient of expansion in high temperature (150～300 ℃) district, can not produce the overvoltage phenomenon, no potential safety hazard.
Claims (3)
1. a superconductive medium electric heater has housing (1), and superconductive medium (2) and electrical heating elements (3) are arranged in the housing (1), it is characterized in that: be connected to cavity plate (4) with described housing (1), between housing (1) and the cavity plate (4) through hole (5) arranged.
2. superconductive medium electric heater according to claim 1 is characterized in that: described electrical heating elements is an electric heating tube.
3. superconductive medium electric heater according to claim 1 and 2 is characterized in that: described through hole (5) is at least three.
