Description

A kind of heating element device
[technical field]
The present invention relates to electric-heating technology field, particularly relate to a kind of heating element device.
[background technology]
Boiler the most on the market, various in style, but universal functionality is single, the especially core distribution of boiler Hot body, uses circulating electrically heated structure mostly, inserts boundling electric heating tube in the heating standpipe that a kind of band is imported and exported Structure, carries out heat exchange by fluid and cluster type electric heating tube and reaches the heated purpose of liquid, but because itself structure designs The drawback such as unreasonable, cause consumer usually to occur when using boiler work burning the problems such as pipe, booster.
According to current technology, existing heat-generating pipe is generally U-shaped heat-generating pipe, all overall heating during energising, but outside heating wire The U-shaped heat-generating pipe tube wall of bending is the most relatively thin, makes outer end, inflection point become thinner in the end of bending because of bending deformation, heating Herein, long-term fever easily makes heat-generating pipe burn pipe to silk, and booster etc., damage rate is high.
And existing heater general the most all at the tube wall of standpipe lower end wire connect and be loaded on the heating wire within heat-generating pipe, Connect water inlet pipe and water outlet pipe at standpipe tube wall opening, thus make to produce on the tube wall of standpipe multiple connection welding, due to stainless The tube wall of steel standpipe is relatively thin, and tube wall is easily produced and damages, to greatly reduce rustless steel water storage by the welding on tube wall The corrosion resistance of pipe, life-time service is susceptible to fistulae, makes be greatly shortened the service life of boiler, and this kind of mounting structure is extremely Complexity, working (machining) efficiency is low, and cost is high, and when high temperature, high pressure occasion use, problem is the most prominent.
In a word, the cold end of the heating wire of existing heat-generating pipe does not modulate, easily burns pipe；And heating wire, retainer ring and tube wall It is required for welding, damages stainless corrosion resistance greatly；Water side is required for freezing with water inlet end being connected and fixes, and installs pole Inconvenience, the popularization and application to current boiler create strong influence, how to solve the difficulty that this industry presently, there are, Become the problem that this field is new at present.
[summary of the invention]
The present invention provide a kind of simple in construction, install easy to connect, whole heater heat-generating pipe and standpipe tube wall solderless Point, heat-generating pipe two ends have the high reliability heating element device of cold end.
For achieving the above object, the present invention provides following technical scheme:
A kind of heating element device, including water inflowing box, standpipe, heat-generating pipe and outlet component, heat-generating pipe is installed on standpipe In, outlet component is installed on the water outlet of standpipe upper end, and water inflowing box is installed on the water inlet of standpipe lower end；Described Heat pipe be use the integrally formed U-tube body of stainless steel material, U-tube body in install be made into integration for heat-generating pipe heating Toroidal helical shape heating wire；The end of described heating wire is athermic linearity and coordinates composition heat-generating pipe with U-tube body Two cold ends in end, two cold ends in end are provided with the wire connecting ends of heat-generating pipe；Described heating wire and the U-tube of heat-generating pipe Body U-bend turns the heater using straight line U-bend of not generating heat bent at cooperation, bent the sending out of straight line U-bend that this heating wire does not generate heat Hot body turns the cold end of U-shaped coordinating composition heat-generating pipe with U-tube body U-bend, constitutes between the cold end of described U-shaped and two cold ends in end The hot zone of this heat-generating pipe linearity.
Preferably, described water inflowing box is provided with enterprising water cutting grafting port and water inlet.
Preferably, described heat-generating pipe is installed in standpipe by retainer ring, and the water inlet sleeve of standpipe lower end is in entering On the enterprising water cutting grafting port of water box, the upper end outlet sleeve of standpipe forms a through water in the lower port of outlet component Circulation road.
Preferably, it is additionally provided with outlet component junction periphery after the wire connecting ends of described heat-generating pipe connects wire and is easy to The high-temperature insulation fluid sealant being sealedly connected and fixed between the two.
Preferably, described water inflowing box and outlet component are high temperature resistant food grade plastic part.
The invention has the beneficial effects as follows:
Relative to existing heating element device, the most all at the tube wall of standpipe lower end, wire connection is loaded on inside heat-generating pipe Heating wire, standpipe tube wall opening connect water inlet pipe and water outlet pipe, the connection control mode of the present invention is by standpipe bottom Arranging water inflowing box, the enterprising water cutting grafting port on water inflowing box is directly socketed on the water inlet of standpipe bottom, thus avoids Standpipe tube wall upper shed and welding water inlet pipe, additionally the end of the heating wire of the present invention be athermic linearity and with U-shaped heat-generating pipe body coordinates two cold ends in end of composition heat-generating pipe, and the wire arranging heat-generating pipe outside two cold ends in end connects End connects heat-generating pipe power supply, thus has stopped at the tube wall of standpipe lower end welding lead attachment means within electric heating tube Heating wire, makes tube wall no-welding-spot and the imperforation of whole heat-generating pipe and standpipe, it is to avoid produce multiple at the U-tube wall of heat-generating pipe Connection welding, it is to avoid tube wall is easily produced and damages by welding, thus ensure that the integrity of rustless steel body, improves rustless steel Heat-generating pipe and the corrosion resistance of standpipe, make be greatly improved the service life of heat-generating pipe.
Use one annular spiral helicine it addition, turn place compared to heat-generating pipe U-tube body U-bend in current heating element device Heating wire, during energising heat-generating pipe entirety heating, but because of heating wire outside heat-generating pipe tube wall the most relatively thin, heat-generating pipe U-bend roll over Place, kink outer end becomes thinner due to bending deformation, and herein, long-time heating causes heat-generating pipe the most easily to heating wire Producing and burn pipe, spoilage is high；Heating wire of the present invention have employed, owing to turning place in U-bend, the heating that straight line U-bend of not generating heat is bent Silk, and turn with U-shaped heat-generating pipe body U-bend coordinates form heat-generating pipe the cold end of U-shaped so that herein kink outer end due to Bending deformation becomes the thinner cold end that partially changes into and does not generates heat, and heat-generating pipe tube wall weakness herein is not produced high cause thermal damage, enters The U-bend protecting heat-generating pipe of one step turns place, prevents hot-spot, can more preferably protect heat-generating pipe, extend the heat-generating pipe use longevity Life, well control current boiler and easily burn pipe, service life short problem.
Meanwhile, the outlet component of water side of the present invention is all to use resistant to elevated temperatures food grade plastic with the water inflowing box of water inlet end Part, safety and sanitation, produce installation simple and convenient.
