During the utility model work, by base the utility model is fixed on the storage tank, electric heating unit that makes external splint and clamping thereof etc. stretches in the storage tank, connect storage tank by water inlet with external pipeline, the heat-generating units heating power after the water heat absorption of the absorber plate of flowing through heats up, enters storage tank from delivery port, by continuous circulation, the water in the storage tank is heated; Outermost electric heating unit can be given water in the storage tank with thermal energy transfer by external splint, and the coolant-temperature gage in the storage tank is raise, and forms the hot water that meets instructions for use; The utility model heat-transfer area is big, and compared with prior art, under the situation of equal-wattage, the utility model can have littler size, and its structure is compact more; Under the washing away of current, less scaling in the absorber plate, it uses reliable, and the heat transfer efficiency height is difficult for short circuit dischange, and security is good.The utility model can be used in family, hotels and other places, is fit to make high-power water heater, hot-water boiler etc.
Above-mentioned absorber plate has following two kinds of technical schemes: one: described absorber plate comprises that some are set up in parallel into flat rectangular metal endothermic tube, and rectangular metal endothermic tube two ends stretch out in respectively outside base and the upper sealing plate.Its two: described absorber plate comprises top panel and the lower panel that be arranged in parallel, and top panel is sealed by side plate mutually with the lower panel both sides, is provided with plurality of support between top panel and the lower panel.Above-mentioned two technical schemes all have advantage simple in structure, easily manufactured.
Heat absorbing units can adopt following several structure: one: described electric heating unit comprises two-layer micarex, and clamping has the mica gripper shoe between the two-layer micarex, and mica gripper shoe surface order is wound with heating.Its two: described electric heating unit comprises two-layer micarex and heating, and described heating is between two micarexs in a zigzag back and forth to be arranged.Heating can be the rounded heating wire in cross section, also can be the rectangular electric heating piece in cross section.
Further improve as the utility model, described external splint is provided with reinforcement outward.Reinforcement can play booster action, makes clamping stronger, simultaneously, itself has the effect of strengthening heat radiation.
