Fig. 3 is a schematic diagram of electric heater of the present invention;
Fig. 4 is the schematic diagram of electrical heater applications of the present invention in heat-exchange system.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, an embodiment of electric heater of the present invention is provided with the square box of a flat, is provided with a storage tank 1 and an electric heater unit 2 that is flat in the casing, is provided with water inlet pipe 4 and outlet pipe 5 on storage tank.Described storage tank comprises a square substrate 11, and the both sides on the substrate 11 are equipped with labyrinth type water channel 12, and the intake-outlet at water channel two ends links to each other with outlet pipe 5 with water inlet pipe 4 respectively.
In the present embodiment, electric heater unit 2 comprises two identical square substrate 21, and substrate surface all is coated with 22, two substrates of Electric radiant Heating Film 21 and links to each other by lead 3, and is provided with an attaching plug 6.Described substrate 21 can have very big selectivity for various dielectrics such as simple glass, conventional ceramic, enamel, mica, quartz glass, devitrified glass, micro-crystalline ceramic, carborundum, preferred devitrified glass or micro-crystalline ceramic.Method in electric heater unit substrate 21 surface plating Electric radiant Heating Film 22 is on the books in the patent application " a kind of Electric radiant Heating Film and manufacture method thereof " (number of patent application 200910108880.3) that the applicant has submitted to.Described Electric radiant Heating Film 22 electricity connection methods are on the books in the patent application " electricity connection method for electric heating film " (number of patent application 200910105806.6) that the applicant has submitted to, its connect electrode be regardless of positive and negative, straight alternating current all can, voltage can be the arbitrary value between 3-400V.
In the present embodiment, two square substrate 21 surfaces of the sidewall of storage tank 1 and described electric heater unit 2 fit tightly.
Certainly, also can only offer labyrinth type water channel 12 on a side of storage tank 1, like this, the electric heater unit 2 that fits tightly with it also only needs to dispose 1 square substrate 21 and gets final product.
The electrode 23,24 that connects of described Electric radiant Heating Film 22 is located at substrate 21 two ends.Described electrode 23,24 fusing points that connect are lower than the Electric radiant Heating Film maximum operating temperature, for guaranteeing to connect electrode safety, reliable, the described electrode inboard that connects also is provided with buffering heat insulating strip 25,26, this heat insulating strip is all the silver oxide coat, reduce silver fully through high temperature and be one with electric membranous layer fusion, described heat insulating strip resistance is minimum, can ignore.Described heat insulating strip is 1～2cm with to connect electric electrode spacing less, and the resistance between them is little, and when electric current was flowed through Electric radiant Heating Film between them, the heat that is produced was few, thereby protection electrothermal film electricity electrode is not burnt out by the heat of Electric radiant Heating Film generation itself.
Electric heater of the present invention can have multiple use, uses very extensive.Can be used as water heater, can be used as the heater of the usefulness of having a bath, can also be as warmer, or the like.Purpose according to different can set different ancillary equipment.As warmer, can be installed on the body of wall that needs the heating room, the floor or any position, very convenient.
Fig. 3 is that of electric heater of the present invention uses schematic diagram.As shown in the figure,, comprise that one has the electric heater 10 of water inlet pipe 4, outlet pipe 5, on outlet pipe 5, be connected with a gondola water faucet 40 as the heater of the usefulness of having a bath.
Fig. 4 is exactly the further application of the invention schematic diagram.As shown in the figure, this heat-exchange system, the electric heater 10 and that has water inlet pipe 4, outlet pipe 5 has radiator 51 compositions one heat-exchange system of water inlet pipe 52, outlet pipe 53, as radiator, can be used for heating of house.Certainly, as the product of a maturation, should also include filling pipe, air bleeding valve and attemperating unit etc. (not indicating among the figure).
Should use among the embodiment, described electric heater 10 is provided with casing, is provided with storage tank and the electric heater unit of bringing the mouth of a river and delivery port in the casing, and described electric heater unit comprises a planar substrates, substrate surface is coated with Electric radiant Heating Film, and described storage tank sidewall and described planar substrates surface fit tightly.
Should be in use with invention, it is static relatively that water in the storage tank keeps when electric heater 10 initial heating, rising along with temperature, the movement rate of hydrone is accelerated gradually, when to uniform temperature, water begins to flow, and enters radiator 51 by storage tank outlet pipe (mouth), and the water at low temperature in the radiator 51 enters storage tank and heats through its outlet pipe, storage tank water inlet pipe (mouth), forms a complete heating, heat dissipation circulating system.
Among the embodiment of this heat-exchange system, because the water channel in the electric heater 10 in the storage tank fits tightly the planar substrates that electric heater unit is coated with Electric radiant Heating Film, and bigger heating surface is not only arranged, and, because the electric conversion efficiency of Electric radiant Heating Film surpasses 95%, the water in the energising rear channel can be heated fast.Therefore the energy consumption of whole heat-exchange system is very low, and energy-conserving and environment-protective are compared with existing heat-exchange system, and the volume of whole system can significantly dwindle, and manufacturing, maintenance cost also significantly reduce.
Although the present invention is described to particularity to a certain degree, please understands current disclosure information and only adopt diagram.Under the situation of not deviation affects spiritual essence of the present invention and scope, when making and arranging the details of various parts, can take a series of change measure.
