Description
(1) technical field: the present invention is the electric heater with the electrical heating water, and belonging to has heat source fluid heater class (F24H) directly not contact switching equipment class (F28D) with heat exchange medium.
(2) background technology: existing electric heater access node structure branch has storage-type and flow-type, and both directly are fixed on electrothermal device in tank or the cavity to contact with water, and cold water is heated through the electrothermal device surface.Electrothermal device has resistance-type, infrared type, PTC formula etc.Resistance-type is enclosed electrothermal tube, is divided into three layers: internal layer is a resistive heater, and the middle level is the insulating materials of parcel, and is outer for isolating anti-creeping metal tube.Thisly directly put electric heater in the what water with electrothermal tube, have following defective: 1. heat makes the thermal efficiency reduce about 25% because of the transmittance process loss.2. electrothermal tube put in the what water long-time, the easily fouling of shell surface, shadow noon heating efficiency, and also can produce the corrosion electric leakage.
It is 60%-80% that the general width of cloth is penetrated element thermal radiation efficient, and the thermal radiation efficient of infrared type electrothermal device can reach 90%.The far infrared radiation temperature can reach about 700 ℃, and novel gluing formula far infrared device then can be competent at more high power high-temperature heating.The infrared type electrothermal device is because the good water channel design that does not match and do not utilize and give full play to benefit, and thus, it is that the electric heater of thermal source has practical value very much that design is penetrated the source with the width of cloth.
(3) summary of the invention: the infrared type electrical water heater with combined water way that the present invention proposes solves existing the conducting heat and the uneasy congruent problem of corrosion electric leakage with the influence of insulation parcel heater that electrothermal tube exists in the what water of directly putting exactly.Its technical scheme is as follows:
Infrared type electrical water heater with combined water way is characterized in that electric heater is provided with around two of infrared type electrothermal device to do and above whenever do the whole water channel that water channel combines; Lumen centers infrared type electrothermal device 4 two end supports are on the axial two ends of water channel; Whenever do and establish internals 1 and outer part 3 in the water channel, both stack peripheral seal welding or nut 7a is tightly connected, and both form water channel between the interlayer; Part outside water channel water (flow) direction two ends is or/and drive delivery port 3a on the internals, connections that match with fixing threeway in this place or two logical side mouth of a river 9a whenever adjacent two done between water channel by adjacent two threeways or two general nut 7b and be tightly connected.
Above-mentioned internals, outer part can all adopt spill, are called indent part or outer recessed, and the cross section that both form between the interlayer is an arc, claims arc water channel 2; Waterway wall can be waveform or profile of tooth along water (flow) direction.
Above-mentioned internals heating surface can be the face of slightly making a list; And can be coated with infrared high-temperature energy-saving coating material.
In above-mentioned inner chamber, can establish vertically a plurality of with respectively do the supports insulative plate 5 that water channel matches, the infrared type electrothermal device passes every insulation board centre bore, and supports onboard, has the through hole 5a of distribution on the supports insulative plate.In above-mentioned inner chamber, the internals heating surface can be established many ribs 11; Outer part outer surface is established many muscle 10.In above-mentioned arc water channel, indent part outer surface is established many fins 12.
Above-mentioned whole water channel is done placate and is generally elected 2～4 as and do.Adopt two do composition whole water channel can be described as a unit, whole electric heater can adopt the overlapping composition of multiple-unit.The above-mentioned water channel of whenever doing all adopts aluminum alloy die casting.Can adopt quartz ampoule infrared type, red far infrared radiation formula or gluing formula far infrared type electrothermal device in the above-mentioned infrared type electrothermal device.Above-mentioned adjacent two do periphery can overlappingly place, or suitably reserves the gap.
Beneficial effect of the present invention:
I. adopt the combination water channel of the periphery that adapts with the infrared type electrothermal device, realize the infrared ray electric thermal device of high efficiency heating can be applied in the electric heater.Solved low, the uneasy congruent problem of the existing electric heater thermal efficiency.Ii. adopt the heater periphery to establish the combination channel structure, help to use multiple following augmentation of heat transfer facility: 1. water (flow) direction adopts wave or profile of tooth to flow in the water channel, increases the flow path and the width of cloth and penetrates face; And be in turbulence state in the water channel, its convection heat transfer' heat-transfer by convection effect is best.2. the internals heating surface adopts rough surface, and absorptance is big, and the favorable for absorption width of cloth is penetrated heat.3. the internals outer surface lays fin in the water channel, increases heat-transfer area, heat output.Iii. the internals inner surface is coated with infrared high-temperature energy-saving coating material, can save energy 20%～28%, (this material is used widely on worker's stove at home).Iv. electrical heating element and water are isolated fully, and is safe and reliable.V. adopt multiple facility, guarantee the water channel mechanical strength: be respectively equipped with muscle and rib at internals inner surface and outer part outer surface, and the supports insulative plate that is provided with, all can be in order to hydraulic pressure resistance and increase mechanical strength.Vi. whenever do water channel and adopt the integral Al-alloy die casting, easily manufactured cost is low.Vii. use maintenance side to make: can get final product from the extraction of magnetic cap if infrared tube is changed in light maintenance.If overhaul, can turn on nut, respectively do water channel separately, but just convenient for maintaining.In sum, this patent is the efficient energy-saving electrothermal hydrophone that high efficiency heater element and efficient heat transfer structure combine, and safe in utilization, make simple, cost is low, easy to maintenance.
