A kind of through type electric water-heating apparatus
A kind of through type electric water-heating apparatus of the present utility model is applicable to the various occasions that need heat water in life and the production field.With this through type electric water-heating apparatus is domestic hot water's water heater that core parts are made, and has the advantage of domestic gas-fired water heater and storage-type domestic, electric water heater, has overcome both shortcomings, uses safer, more convenient.The little heating of composite semiconductor that has the PTC semiconductor heater element of high electric conversion efficiency or a DZR when use also has remarkable energy saving effect during as the heating of this through type electric water-heating apparatus.
To the heating of water, various methods were arranged, general common method mainly contains three classes in the past: a class is the fuel combustion heating; One class is electrical heating; Another kind of is the chemical reaction heating.In the heating means of these types to water heating, what have substantial connection with masses is preceding two classes.And along with the progress of society, electricity consumption is very general to the method for water heating.Single with regard to the situation of the present family expenses storage-type electric water heater of China, just there are a lot of enterprises of the various places that spread all over the country to produce in a large number.But the electric heater of these storage-types all has shortcoming, must preheating before its uses, and preheating time is long, and the capacious electric heater of storage tank is longer its preheating time, and power consumption is big, the use cost height, and can't the long-time continuous hot-water supply, use very inconvenient.Fuel combustion heating class water heater is at present also in a large amount of productions, but the safety problem that the pernicious gas that fuel combustion produces causes is the hidden danger of this series products always; This class water heater volume is big, the subsidiary container that charges, and it is big to take up room.Development and production through type electric heater is attempted by some enterprise in addition, also since its structure and principle can't reach electric and do not accepted by people by the requirement of full use.
A kind of through type electric water-heating apparatus of the present utility model can overcome above shortcoming, and providing that a kind of volume is tiny can be by the complete convenient electric water-heating apparatus that uses.Its use cost is also relatively low.
A kind of through type electric water-heating apparatus of the present utility model, be undulatory metallic water pipe to be made in bending weld respectively or closely be crimped on the face of two metallic plates, perhaps on thicker sheet metal, leave the intensive hole parallel, as the heat conduction with to the hot structure of water man with metal flat; Have the hole of consistency from top to bottom on the metal heat-conducting plate, use when fastening heater element in these holes; After heater element is isolated with resistant to elevated temperatures heat conduction good insulation performance material, be positioned on the electrode of two gold dollar spares and draw lead, water pipe on the thermal conductive metal plate is connected with the penstock of running water, open valve, connect the power supply of heater element, heater element generates heat rapidly, and by the metal heat-conducting plate heat is transmitted to water pipe the water in the heater water pipe of flowing through is directly heated, and obtains hot water continuously.When the electrical power of discharge that flows through heater and heating cooperates when appropriate, connect about 30 seconds behind the power supply, can obtain hot water.
A kind of electric water-heating apparatus of the present utility model, its structure be as shown in the figure: 1 is heating among the figure; The 2nd, metal electrode; The 3rd, the thermostable heat-conductive insulating materials; The 4th, the metal heat-conducting plate; The 5th, bend to undulatory metallic water pipe; The 6th, contact conductor; The 7th, holding screw; The 8th, inlet valve.
Be that to implement a kind of through type electric water-heating apparatus of the present utility model be one of scheme of the electric heater made of core parts below: use structure as shown in the figure, design power is 10% for the 2000W error; Wherein 1 heating is with PTC semiconductive ceramic heater; The parameter request of this heater is, more than the withstand voltage 400V, 200～300 ℃ of surface temperatures, normal temperature resistance value are 0.8～5K, and monolithic is of a size of 24MM * 15MM * 2.5MM or other similar sizes; Its power is by average every 100W configuration; 2 metal electrode is decided according to the virtual electrode contact-making surface of PTC element with fine aluminium or low-alloy aluminum, its size, is 110MM * 15MM * 0.4MM in this programme.3 conduction insulating materials pi film; 4 metal heat-conducting plate brass sheet, thickness is greater than 1MM; 5 metallic water pipe bends with copper tube, and the copper pipe internal diameter is 5MM; 6 the contact conductor high temperature resistant wire of sectional area more than or equal to 1 square of MM; 7 holding screw CARBURIZING FURNACE FOR STAINLESS FASTENER and nut; After a kind of through type electric water-heating apparatus of the present utility model installation, connecting corresponding water power control section, add shell, has been exactly a complete through type electric heater.The appearance and size of the electric heater material object of this programme is 15CM * 20CM * 6CM; Can be when environment temperature is 20 ℃ with the about 50 ℃ hot water of the continuous output temperature of the flow of 1L/MIN; Being fit to kitchen, shower or other occasion uses.
Comprehensively above-mentioned, utilize a kind of through type electric water-heating apparatus of the present utility model to be core component The various water heaters of making, it is little, easy to use to have a volume, installs easily, and security performance is good Etc. advantage; When its heating uses PTC element or the little heating of DZR, also have very Good energy-saving effect. A kind of electric water-heating apparatus of the present utility model has good application prospect.
