Abstract
The invention provides a novel helix-tube type forced circulation electric heater composed of a ceramic heat-emitting tube, a helical fin heating tube, a flow-limiting tube and a silica gel heat insulating sleeve. According to the specific structure which is shown as a picture of the abstract, the ceramic heat-emitting tube is installed in the helical fin heating tube, the helical fin heating tube is tightly sleeved with the flow-limiting tube, and the flow-limiting tube is tightly sleeved with the silica gel heat insulating sleeve. In the practical use, firstly, the helical fin heating tube is heated by the ceramic heat-emitting tube arranged in the middle of the heater, then water is heated by the heating tube, due to limitation of the flow-limiting tube, the heated water is continuously heated and rises along a helix tube formed by fins and the flow-limiting tube, and finally the water reaches to the top layer of a water tank. If the instant-heating mode is applied, the hot water in the top layer can be directly conveyed out. Normally, the optimal installation mode is that the heater is perpendicularly installed, so that pollution discharge is facilitated. If a water inlet of the flow-limiting tube specially faces downwards and a water outlet of the flow-limiting tube specially faces upwards, the heater can be horizontally installed on different layers of the water tank, and therefore layered heating can be achieved.
Description
Affiliated field: the heater of electric heater
Technical background: what storage-type electric water heater generally adopted at present is that stainless steel electrical heating adds directly heating water body of pipe, because the type heater heated surface area is less, easily fouling, and the problems such as power is non-adjustable, be subject in actual use a lot of restrictions, if immediately do not clear up incrustation scale, easily do not caused the fusing of heating tube hot-spot heating wire that the accidents such as electric leakage occur.
Summary of the invention: in order to solve with first-class problem, the present invention adopts the ceramic electric heating Manifold technology, helical fin heat transfer technology of current comparative maturity and unique current limiting tube and collet etc. through integrated innovation, form Novel spiral forced circulation heater, make heater realize electricity separation truly, heating surface (area) (HS increases more than 5 times, current limiting tube makes to be subject to hot water to force uninterrupted heating fast in helix tube, and high-temperature-hot-water reaches rapidly top layer.Because water body flows at heater surfaces fast, heater surfaces non flouling behaviour, ceramic heating pipe surface area is larger, adopts many small power electric heated filaments to heat side by side, reaches power adjustable, and unit are caloric value is little, is not prone to the problems such as hot-spot.
The technical solution adopted in the present invention: this heater is comprised of ceramic heating tube (figure-1), helical fin water body heating tube (figure-2), current limiting tube (figure-3) and silica gel collet (figure-4) four parts.Concrete structure is as shown in figure-5, and ceramic heating pipe is installed in the middle of helical fin heating tube, and current limiting tube is tightly placed on helical fin heating tube, and silica gel collet is tightly enclosed within the outside of current limiting tube.Heat-generating pipe heating spiral fin coil in heater center, spiral fin coil heats water body again, is subject to hot water under the restriction of current limiting tube, to force laser heating in helix tube, and makes water body rapid flow, forces high-temperature-hot-water to be transported to water tank top layer.
The technical problem underlying that this heater solves:
(1) safety of ceramic heating tube and life-span, solution is that heating wire is wrapped on ceramic base tube side by side, and then wraps one deck hard-paste slurry sintering, and heating wire is all wrapped up by pottery, not only insulate but also protect heating wire not oxidized.
(2) thermal efficiency problem, solution is that helical fin heating tube is formed with aluminum alloy rolled or casting, aluminium alloy heat transfer efficiency is high.
(3) aluminium alloy helical fin heating tube with heat-generating pipe cooperation, solution is the taper that heat-generating pipe and helical fin heating tube inner tube are all processed into identical tapering.
(4) current limiting tube is with the cooperation of helical fin heating tube, solution is to make full use of the aluminium alloy larger advantage of swollen system of splashing, by the two being installed together after heating current limiting tube and cooling spiral fin heating tube, after normality, make the two reach interference fit, between fin and current limiting tube, form the continuous helical pipeline without overflow, water laser heating conveying are caused to top layer (automatically upwards mobile after water heating), silica gel collet is contained in the outside of current limiting tube, main purpose is to reduce to greatest extent the outside heat radiation of current limiting tube, to improve the temperature of in-pipe flow speed and top layer water.
Beneficial effect: it is completely separated that this electric heater can reach water power, heating tube non-scaling, safety, the thermal efficiency is high, power is adjustable, and high-temperature-hot-water reaches rapidly top layer, can be in a machine realizes water storage and two kinds of mode commons of instant heating with same heating tube in the situation that.Current limiting tube makes water in heat exchange, form fixing circulation, incrustation scale can be taken to heating tube water inlet below, is convenient to periodic cleaning.
