Background technology:

At present, the heat exchanger of domestic heat pump water heater is if there are serious problems such as fouling, perforation in direct and water contact heat-exchanging, if then there are the low problem of heat exchange efficiency in indirect and water heat exchange.

Summary of the invention:

The purpose of this utility model is to provide a kind of superconducting fluid high-efficiency heat pump heat-exchanging water tank that has double-layer inner containers and all be provided with heat exchange coil in inner water tank internal layer bottom surface and side, it is the double-layer inner containers interlayer to be vacuumized, inject superconducting fluid and inner bag internal layer bottom surface and side thereof heat exchange coil is set, not only thoroughly overcome problems such as heat exchanger coils fouling, perforation, and improved heat exchange efficiency.

Formation of the present utility model: form by inner bag internal layer, inner bag skin, outer courage, superconducting fluid, coil heat exchanger, polyurethane thermal insulation layer, water inlet pipe, outlet pipe and superconducting fluid ascending pipe.At the upper base 6 and cylinder type inner bag internal layer 7 outsides of going to the bottom between 16 is inner bag skin 8, the outside of inner bag skin 8 is outer courage skins 10, the all or part of winding coil pipe 5 of bottom surface and side at inner bag internal layer 7 noncontact water, form coil heat exchanger 17, compressor 19 is connected with coil heat exchanger 17 imports by high-voltage tube 1, outlet is connected with compressor 19 with evaporimeter 2 by expansion valve 3, form between inner bag internal layer 7 and the inner bag skin 8 and press from both sides into space 11, superconducting fluid 12 is arranged in pressing from both sides into space 11, inner bag internal layer 7, form outside the inner bag and between the outer courage skin 10 and press from both sides into space 13, polyurethane foaming layer 14 is arranged in pressing from both sides into the space, stretch out outer courage outer 10 outer outlet pipe 4 and water inlet pipe 18 installing up and down of inner bag internal layer 7, install on the layer 8 outside the tank stretch out outer courage skin 10 and with the superconducting fluid ascending pipe 9 that presss from both sides into space 11 connections.

Compared with the prior art, the beneficial effects of the utility model: the one, coil heat exchanger can scaling, does not exist because of the scaling corrosion and causes copper pipe perforation, degradation problem under the heat exchange efficiency, the stability and the life-span of having improved heat pump water-heating machine greatly; The 2nd, heat exchange efficiency is greatly improved, be delivered to the bottom surface and the side of inner bag internal layer rapidly by superconducting fluid because of the heat in the coil pipe, and the area of inner bag inner layer cylinder side and bottom surface is the several times of coil pipe heat transfer area, be equivalent to enlarge the heat exchange area of several times coil pipes by superconducting fluid, so heat exchange efficiency has obtained increasing substantially.

The specific embodiment:

As Fig. 1, shown in Figure 2, at the upper base 6 and cylindrical shape inner bag internal layer 7 outsides of going to the bottom between 16 is inner bag skin 8, the outside of inner bag skin 8 is outer courage skins 10, the all or part of winding coil pipe 5 of bottom surface and side at the noncontact water of inner bag internal layer 7, form coil heat exchanger 17, compressor 19 is connected with coil heat exchanger 17 imports by high-voltage tube 1, the coil pipe outlet is connected with compressor 19 with evaporimeter 2 by expansion valve 3, form between the bottom surface of the bottom surface of inner bag internal layer 7 and side and inner bag skin 8 and the side and press from both sides into space 11, by superconducting fluid ascending pipe 9 the airtight space 11 that presss from both sides into is vacuumized, in pressing from both sides into space 11, pour into superconducting fluid 12 then, inner bag internal layer 7, form between inner bag outer 8 and the outer courage skin 10 and press from both sides into space 13, press from both sides into space 13 and outside on the courage between top and the upper base 6, and outer courage is gone to the bottom and is gone to the bottom and pours into polyurethane foaming layer 14 between 16, form the insulation layer, inner bag internal layer 7 outlet pipe 4 and the water inlet pipe 18 stretch out outer courage skin 10 be installed up and down, install on the layer 8 outside the tank stretch out outer courage skin 10 and with the superconducting fluid ascending pipe 9 that presss from both sides into space 11 connections.

Operation principle: during compressor 19 runnings, output HTHP Working medium gas enters coil heat exchanger 17 from high-voltage tube 1, coil heat exchanger 17 is with heat transferred superconducting fluid 12, superconducting fluid 12 is evaporated rapidly the bottom surface and the side of heat transferred inner bag internal layer 7, inner bag internal layer 7 is again the water in the heat transferred inner bag 15, thereby heats water to about 55 ℃.

After coil heat exchanger 17 heat exchange, by coil pipe 5 output cryogenic high pressure working medium, this working medium enters evaporimeter 2 after expansion valve 3 step-downs, absorb in the air and flash to the low-temp low-pressure Working medium gas rapidly behind the heat, this Working medium gas is inhaled into compressor 19 by the compressor return air pipe, be compressed into the output of HTHP Working medium gas once more, such process is back and forth carried out, and produces hot water thereby constantly produce heat.
