Abstract
Electric tubular liquid heater for electric boiler, electric shower bath and other liquid heating equipment has several cascade thin hollow metal plate heat absorbers having squered pipes inside it to constitute one communicated pipeline with water inlet and outlet in two ends; and heating bodies between two adjacent heat absorbers and with metal electrodes connected via edge terminals to power supply and insulated from heat absorbers. The present invention has the features of large heating area, high heat converting efficiency, fast temperature raise, high reliability, etc. and excellent power saving and environment protecting effect.
Description
The present invention relates to a kind of liquid heater that is used for liquid heating apparatus such as electric boiler, electric shower-bath, particularly relate to a kind of electric tubular liquid heater.
At present, water heater mainly contains following two big classes: a class is that combustion gas is Instant heating type, and this class water heater causes its thermal conversion rate low because of its mode of heating, can produce pernicious gas in the use, contaminated environment, and inflammable, explosive, easily cause human casualty accident.This for this reason water heater is eliminated.And during the current forced-ventilated gas water heater exhaust of generally using, easily produce negative pressure, and noise is big.So only should use, but central hot water apparatus mode causes water resource waste serious as central heater; Another kind of is the electric heating storage-type.Its defective is that volume is big, and it is many to take up room, and preheating time is long, can not use continuously, and heat leaks very big.Existing electric thermostatic type water heater is owing to using traditional exothermic material to cause thermal conversion rate low, and service life is not long, and problem such as in use, corrosion can appear in heating, easily leaks electricity, and safety coefficient is not high.Since the semiconductor exothermic material comes out, multiple semiconductor liquid heater has also appearred, and its great majority are small-sized water tank type.Can't produce in batches owing to its design problem.Therefore in fact the semiconductor liquid heater is not fully used.
The object of the present invention is to provide a kind of heating surface (area) (HS big, thermal conversion rate height, liquid heat up rapidly, and be safe and reliable, has the electric tubular liquid heater of good energy-conservation and environment protecting.
For achieving the above object, the invention provides a kind of electric tubular liquid heater, this heater is linked to each other by a plurality of ultrathin hollow slab shape metal sink 1 stacks, be provided with the square waveform pipeline in each heat dump, pipeline in a plurality of heat dumps is linked to be a pipeline that communicates, the two ends of pipeline are entery and delivery port 11,12, be provided with a heater 2 between per two adjacent heat dumps, the two sides of heater is provided with metal electrode 3, its edge is provided with the binding post 4 with used for electric power connection, is separated by insulating materials 5 between metal electrode and the heat dump.
Pipeline in the described metal sink 1 is separated with housing by multi-disc reinforcement, heat absorbing sheet 15, and cross-section of pipeline can be square, circular or other shape.
A plurality of metal sinks 1 stack back is connected and fixed with bolt.
Described heater 2 adopts the semiconductor heating board.
Good effect of the present invention is, owing to adopted current state-of-the-art exothermic material-semiconductor heating sheet, and above-mentioned heating sheet is close between adjacent two heat dumps, thereby make thermal conversion rate significantly improve.Because the pipeline in the metal sink is separated into the square waveform pipeline by the metal reinforced sheet, not only increased the endotherm area of water, and convection current is better.Increase the intensity of heat dump simultaneously, reduced the thickness of metal material, made thermal conversion rate higher, reached energy-conservation purpose.Because water is at short notice, through a plurality of heat dumps, absorbed a large amount of heats, water temperature is risen rapidly, reaching is thermal effect.So, and can use hot water continuously without preheating.Because of it does not need storage tank,, realized ultrathin type so volume is little.Simultaneously, during the heating of this heater, the flames of anger is not burnt, and does not have waste gas to discharge, and is pollution-free; Do not have mechanical oscillation, therefore noiseless is the environment-friendly type heater.This heater has adopted novel heating element heater, and its metal electrode does not contact with water in the square waveform tube type metal heat dump pipeline, by encapsulation process, keeps dry between adjacent two heat dumps, accomplishes that really water power isolates, and has avoided electric leakage, reaches safety standard.Therefore, be not subjected to the restriction of installation site, can be installed in from the nearest place of usefulness water out, thus can using water wisely.This heater die forming, technology is simple, exquisiteness is attractive in appearance, cost is low, practicality is high, can be mass-produced.
The invention will be further described below in conjunction with accompanying drawing and a preferred embodiment.
