Abstract
The utility model relates to an electrothermal film heater. The utility model is characterized in that the utility model comprises at least one electrothermal membrane pipe and a header sealing connected to both ends of the electrothermal membrane pipe. The two headers are respectively provided with a water inlet and a water outlet. One header is furnished with a water level sensor and a temperature sensor inside. The part close to both ends of each electrothermal membrane pipe is respectively provided with an electric pole. The electric pole is connected with both ends of the electrothermal membrane pipe's electrothermal membrane. The utility model makes use of the electrothermal membrane pipe as a calandria. Medium heated flows through the pipe. Heat exchange area is very big. In the case, the utility model largely increases the heat efficiency. The electrothermal membrane is sealed in the glass tube without contacting air. Therefore, the electrothermal membrane is not easy to oxygenize, which prolongs the service life. The utility model has simple structure. Multiple electrothermal membrane pipes can be paralleling connected between two headers as required with strong applicability.
Description
Technical field
The utility model relates to a kind of electric heater, particularly a kind of electrothermal film heater, any utensil that can be used for various water heaters, electric heater and liquid is heated.
Background technology
Existing electric heater generally adopts heating wire or bar to place in the heated medium or outside the container, its shortcoming is that the contact area of electric heating element and heated medium is little, and intensification is slow and the heat efficiency is lower; The easy oxidation of electric heating element, useful life is short.
Summary of the invention
The purpose of this utility model just provides a kind of electrothermal film heater, to solve the easy oxidation that existing electric heating element exists, the problem that useful life is short, the heat efficiency is lower.
The technical solution of the utility model is: comprise at least one electric heating membrane pipe and the header that is sealedly connected on its two ends, on two headers, be respectively equipped with water inlet and delivery port, in a header, level sensor and temperature sensor are installed, the outside, place, close two ends at every electric heating membrane pipe is provided with electrode, and this electrode is connected with the Electric radiant Heating Film two ends of electric heating membrane pipe.
By the silicagel pad sealing, the nut by connecting rod and two ends thereof between two headers is fastenedly connected between the header at described electric heating membrane pipe and its two ends.
The utility model utilizes electric heating membrane pipe as calandria, and heated medium flows through in the pipe, and heat exchange area is very big, has improved the heat efficiency and programming rate greatly.Electric radiant Heating Film is difficult for oxidation, long service life.Simple in structure, a plurality of electric heating membrane pipes in parallel between two headers as required, applicability is very strong.
Description of drawings
Fig. 1 is the structural representation that the utility model has the embodiment of an electric heating membrane pipe;
Fig. 2 is the structural representation that the utility model has the embodiment of two electric heating membrane pipes.
Embodiment
Referring to Fig. 1, this embodiment of the utility model comprises an electric heating membrane pipe 7 and is sealedly connected on the header 1 at its two ends, is respectively equipped with water inlet and delivery port on two headers 1, and level sensor 2 and temperature sensor 3 are installed in a header 1.Electric heating membrane pipe 7 is by insulation tube wall (generally being made by glass) and be compounded in its surperficial Electric radiant Heating Film (hyaline membrane) formation, also can be at the compound layer protecting film in the Electric radiant Heating Film outside.Electric radiant Heating Film two ends in the outside of every electric heating membrane pipe 7 are provided with electrode 6, are connected with the power end of controller during use.By silicagel pad 5 sealings, nut 4 and packing ring by connecting rod 8 and two ends thereof between two headers 1 are fastenedly connected between the header 1 at electric heating membrane pipe 7 and its two ends.
Referring to Fig. 2, this embodiment is provided with two electric heating membrane pipes 7 between two headers 1, and other structure is identical with a last embodiment.
The quantity of electric heating membrane pipe 7 of the present utility model can be provided with many as required, can set or become regular polygon or any layout in a row.The utility model also can be provided with casing according to the needs of concrete application and be enclosed in the outside, electric heating membrane pipe 7 is shielded, and have decorative effect.
The utility model connects temperature controller on temperature sensor 3 when using, on demand control water temperature.Level sensor 2 is used for controlling the break-make of electric heating membrane pipe 7 power supplys, cuts off the power supply of electric heating membrane pipe 7 when water level is lower than this position, prevents that dry combustion method from causing Electric radiant Heating Film to damage.
Claims (2)
