Abstract
A horizontal water tank heat exchanger of a heat pump water heater, comprises a heat exchange tube which is provided with a gas phase working substance inlet, a liquid phase working substance outlet,a phase change heat exchange area, a hydraulic seal area and a transfusion area; and is characterized by further comprising a seal cover fixing the heat exchange tube; wherein the transfusion area isa straight tube; the phase change heat exchange area is a spirally coiled tube, with flow passage height thereof continuously descending along a heat pump working substance flowing direction; and thehydraulic seal area is a circular tube, with an included angle +/- alpha between the plane of the flow passage thereof and the vertical direction being 0 to +/-25 DEG. The heat exchanger has the advantages of easy mounting and demounting and fully using all the heat exchange surface of the heat exchanger so as to help to improve the efficiency of the heat exchanger and the like.
Description
Technical field: the present invention relates to a kind of horizontal water tank heat exchanger of heat pump water heater, it is applicable in the horizontal water tank that product such as storage-type Teat pump boiler uses.
Background technology: the Teat pump boiler of the horizontal water tank of known employing, its heat exchanger is generally the prepackage type structure, in the water tank manufacture process, heat exchanger is fixed on the water tank exactly, in water tank completion back or use, if heat exchanger needs repairing, it is local or all disassemble to water tank just to have to, not only workload is big but also maintenance cost is high, and some similar structure is actually and can't keeps in repair.Because most prepackage type heat exchangers have some zones to touch water tank wall or heat insulation layer, have only heat exchange surface and water about half to carry out effective exchange heat usually, so heat exchange efficiency are lower.In addition, the residing spatial altitude of heat exchanger is less in the horizontal water tank, some heat exchanger tubes are because its structure fails to guarantee that the runner height of phase inversion hot-zone descends continuously along the heat pump fluid flow direction, thereby the unusual viscous flow clogging that occurs liquid refrigerant in this zone, stable operation to heat pump assembly causes harmful effect, reduces operational efficiency simultaneously.In order to overcome these defectives, horizontal water tank heat exchanger of heat pump water heater is developed.
Summary of the invention: technical problem to be solved by this invention is that a kind of horizontal water tank heat exchanger of heat pump water heater will be provided, and it can be convenient to installation and removal effectively, and makes full use of whole heat exchange surfaces of heat exchanger, thereby helps improving efficiency of heat exchanger.
The technical solution adopted for the present invention to solve the technical problems is:
It comprises heat exchanger tube, heat exchanger tube is provided with the import of gas phase working medium, liquid phase working fluid outlet, phase inversion hot-zone, wet seal area and transfusion zone, it also comprises the fixedly capping of heat exchanger tube, described transfusion zone is a straight tube, the phase inversion hot-zone is the helical form coil pipe, phase inversion hot-zone runner height descends continuously along the heat pump fluid flow direction, and wet seal area is an arc tube, and the angle α between plane, wet seal area runner place and the vertical direction is 0～± 25 °.
It also comprises guide rod base, guide rod, guide rod fixture, and the guide rod base is fixed on the inner water tank, and the guide rod fixture is installed in the capping, and the two ends of guide rod are respectively by guide rod fixture and guide rod base location.
Angle α between plane, wet seal area runner place and the vertical direction be ± 3 °, ± 7 °, ± 12 °, ± 15 °, ± 20 ° etc.
The present invention compares the beneficial effect that is produced with background technology:
1, because the present invention adopts the fixedly capping of heat exchanger tube, the transfusion zone of heat exchanger tube is a straight tube, the phase inversion hot-zone of heat exchanger tube is the helical form coil pipe, phase inversion hot-zone runner height descends continuously along the heat pump fluid flow direction, the wet seal area of heat exchanger tube is an arc tube, angle α between plane, wet seal area runner place and the vertical direction is 0～± 25 °, all heat exchange surfaces fully contact with water and carry out exchange heat, so it can be convenient to installation and removal effectively, and make full use of whole heat exchange surfaces of heat exchanger, thereby help improving efficiency of heat exchanger.
Description of drawings: Fig. 1 is a structural representation of the present invention.
Fig. 2 is the schematic diagram of the angle ± α between wet seal area 8 planes, runner place and the vertical direction among Fig. 1.
The specific embodiment: shown in accompanying drawing 1, the present invention includes heat exchanger tube 1, heat exchanger tube 1 is provided with gas phase working medium import 5, liquid phase working fluid outlet 3, phase inversion hot-zone 7, wet seal area 8 and transfusion zone 6, gas phase working medium import 5 is communicated with the top of phase inversion hot-zone 7, the end of phase inversion hot-zone 7 is communicated with the top of wet seal area 8, the end of wet seal area 8 is communicated with the top of transfusion zone 6, and the end of transfusion zone 6 is communicated with liquid phase working fluid outlet 3.
The present invention also can comprise the fixedly capping 2 of heat exchanger tube 1, described transfusion zone 6 is a straight tube, phase inversion hot-zone 7 is the helical form coil pipe, phase inversion hot-zone 7 runner height descend continuously along the heat pump fluid flow direction, wet seal area 8 is an arc tube, and the angle α between wet seal area 8 planes, runner place and the vertical direction is 0～± 25 °.
The spiral coil structure is adopted in phase inversion hot-zone 7, its runner height descends continuously along the heat pump fluid flow direction, to prevent owing to the liquid heat pump fluid that condenses in heat transfer process remains in a standstill in this zone, thereby and cause occurring the proper flow that vent plug hinders heat pump fluid, the heat exchanging process causes harmful effect.Wet seal area 8 is an arc-shaped structure, its plane, runner place be the approximate vertical state (the angle α between wet seal area 8 planes, runner place and the vertical direction can be ± 2 °, ± 3 °, ± 5 °, ± 6 °, ± 7 °, ± 8 °, ± 9 °, ± 10 °, ± 11 °, ± 12 °, ± 15 °, ± 20 ° etc.), be convenient to form stable liquid phase surface, prevent that bubble from entering transfusion zone 6.In the present embodiment, because the height of horizontal water tank inner space is less, being not suitable for heat exchanger vertically installs, heat exchanger need be in tilted layout, so keep the dimensionally stable of heat exchanger tube 1 with guide rod 9, guide rod base 10 and guide rod fixture 4 are used for location, guide rod 9 two ends, descend continuously along the heat pump fluid flow direction with the runner height of guaranteeing phase inversion hot-zone 7, and this is to guarantee that heat pump can be stablized, the efficiently important measures of operation.Heat exchanger tube 1 and guide rod fixture 4 are installed in the capping 2, are convenient to installation and removal.
