Summary of the invention

The object of the present invention is to provide a kind of fluid heater to substitute the instantaneous heat hydrophone, it can become hot water, hot gas to cold water, cold air.For achieving the above object, the present invention has adopted following technical scheme: a kind of fluid heater, it is characterized in that it is connected and composed by two coaxial interior pipes and the outer tube pipe cap component by two tube ends, pipe cap component seals ends of tubes, heating wire is contained in the interior pipe, form a chamber in described between pipe and the outer tube, on pipe cap component, be provided with heating wire lead fairlead, an inflow entrance and flow export are set on outer tube wall at interval.

The insulation division of the connecting portion that links to each other with outer tube of pipe and the heating wire wire insulation that interior pipe is drawn to the outside in above-mentioned pipe cap component is divided into; Connecting portion be provided with one insert in effective through hole, around through hole, establish one and the coaxial outer tube of through hole and insert cannelure, in insulation division is provided with the pipe patchhole and with this in the pipe patchhole is communicated with also coaxial lead fairlead.

Above-mentioned connecting portion and insulation division are separated.

Above-mentioned interior pipe, outer tube are all made by clear glass.

Above-mentioned outer tube also can be made of metal.

In the chamber in above-mentioned between pipe and the outer tube rectification part is housed.

According to the present invention, when needed as long as can obtain hot water or hot gas rapidly once switching on, so can not waste energy, structure is also simple, can also pack it in the very narrow slit into by the change shape, is applicable to lavatory hot water, the first-class various uses of gas blowout.

If pipe cap component is divided into the connecting portion that connects inner and outer pipes and makes interior pipe guide to the insulation division of outside heating wire conductor insulation, then can solve the problem of the sealing of leaking.

If inside and outside two pipes all are transparent glass tubes, then the red heat of heating wire and the flow regime of water are come into plain view, be convenient to grasp.

If the periphery at interior pipe encloses a rectification element, can improve rate of heat exchange again.

The specific embodiment

As shown in Figure 1 and Figure 2: present embodiment is the straight pipe type heater.The heating wire 1 of spiral form is equipped with in inside, has coaxially adorned a transparent glass inner tube 2, and its two ends are sealed.Also having adorned one is transparent glass outer tube 3 equally, and its diameter is bigger than interior pipe 2, and its end is uncovered.The pipe cap parts that the end of two pipes 2,3 makes of synthetic resin couple together.Pipe 2 is from sealed at both ends lead 1a that draws heating wire 1 respectively in above-mentioned.The insulation division 4b of the connecting portion 4a that links to each other with outer tube of pipe and the heating wire lead that interior pipe is drawn to the outside in pipe cap component is divided into; Connecting portion has one to insert interior effective through hole 5.Around this through hole 5, establish one and through hole 5 coaxial outer tubes and insert cannelure 6.Pipe patchhole 7 in insulation division is provided with, with should in pipe patchhole 7 be communicated with the lead fairlead 8 of also coaxial formation.The end of interior pipe 2 is inserted in the above-mentioned interior pipe patchhole 7.Connecting portion 4a and insulation division 4b are separation configuration.The both ends open of outer tube 3 is sealed by the mode in the cannelure 6 that inserts connecting portion 4a, and lead 1a is insulated by seal 9 in insulation division 4b.Outer tube 3 touches at length direction on the wall of both end sides and is provided with an inflow entrance 10 and flow export 11, and the chamber between interior pipe 2 and the outer tube 3 plays the effect of cold cover.So when heating wire 1 was in running order, water or gas flow to flow export 11 from inflow entrance 10, are heated in process of flowing.

The heater inner and outer pipes of embodiment all is transparent glass tube, so can be easy to confirm from the outside red heat of heater and the mobility status of water.When breaking down, can judge its reason immediately, have a power failure with decision and still cut off the water supply.

Also utilized the form that pipe cap component 4 is divided into connecting portion 4a and insulation division 4b in addition.So it plays the effect of cold water jacket, even connecting portion leaks, be seeped into pipe cap component inside or surperficial water and also can be prevented from the line of demarcation portion of connecting portion 4a and insulation division 4b, can not soak lead.

The heater of this structure be we can say except the small-sized and straight tube and can also be selected arbitrary shape, and it is packed in the very narrow slit, just can obtain hot water immediately, so it can provide the hot water of lavatory hot-water nozzle aequum.If utilize inflow entrance 10 and flow export 11 as air scoop, can also blow out hot blast.So load onto two water heaters of hot water and hot blast, it is higher that the value in the lavatory will become.

In the foregoing description, entry and water outlet are located at respectively on the two ends wall on the length direction, and which is all right as water inlet.Append a mouth again on the wall in the middle of being positioned at, the water that injects from the both sides mouth is flowed out from middle port.Otherwise the water that injects from middle port also can flow out from the both sides mouth.In order to improve rate of heat exchange, position of each mouthful and quantity can be changed arbitrarily.Fluid as heating target is not limited only to water, as the air example that we enumerate, also has other all liquid, gas to use.

The variation of rate of heat exchange not only contains position and the quantity that influences inflow and outflow, and flowing of fluid also can change.Below, we are to passing through flowing of control fluid, and the embodiment that improves rate of heat exchange once illustrates.As shown in Figure 3: the chamber between the inner peripheral surface of the outer peripheral face of interior pipe 2 and outer tube 3 has been installed a commutator segment 12 as the continuous helical shape of rectification element.

The present invention is transparent glass is made except interior pipe and outer tube, can also adopt metal or pottery to make.If make outer tube with metal.So outer tube is carried out tapping processing, be screwed into pipe joint etc. again, just can establish inflow entrance and flow export simplyr, moreover can also make the root of inflow and outflow mouth have very strong rigidity.

Interior pipe is irrelevant with material, and the inside can also the filling inert gas.The rectification object also may not form spiral helicine commutator segment continuously in interior pipe, can or intermittently establish some commutator segments or the shape that heating wire is rolled into coiled type is got final product at the outer tube inner face.
