Abstract
The utility model relates to a composite heat exchange and water storage type heat pump water heater, which belongs to the technical field of domestic electric appliances. The water heater comprises a liner with a water inlet and a water outlet and a heat exchange tube, both ends of the heat exchange tube are respectively connected with a heat pump system, and the heat exchange tube consists of an external section and an internal section; the external section is wound on the outer wall of the liner; the internal section is arranged in the lower part of the liner; and the external section is communicated with the internal section. During operation, the heat exchange medium of the heat pump system first enters the external section to indirectly exchange heat with the water in the liner via the liner wall, and after being cooled, the heat exchange medium enters the internal section to directly exchange heat with the water in the liner via the tube wall. Since the high-temperature high-pressure gaseous heat exchange medium exhausted by a compressor fulfills sensible heat exchange outside the liner and then enters the liner to carry out condensation heat exchange, the heat exchange temperature of the tube wall directly contacted with the water in the liner is decreased, and under the circumstance of high heat exchange efficiency, scaling is remarkably reduced.
Description
Technical field
The utility model relates to a kind of Teat pump boiler, and especially a kind of compound heat exchange storage-type Teat pump boiler belongs to household electrical appliance technical field.
Background technology
Teat pump boiler has good energy-saving effect, is therefore promoted rapidly.Understand according to the applicant, the heat-exchange tube of existing Teat pump boiler and the combination of water heater water storage liner have two classes: a class is an external, and promptly the heat exchange pipe is coiled in inner bladder outer wall, with the water indirect heat exchange in the inner bag; Another kind of is built-in, and promptly the heat exchange pipe is placed in the inner bag, with the water direct heat-exchange in the inner bag.The former shortcoming is that heat exchanger effectiveness is relatively low, and the latter's shortcoming then is because the initial temperature of the interior medium of heat-exchange tube is higher, and therefore easy tube wall incrustation causes heat exchanger effectiveness to descend.In addition, existing built-in heat-exchange tube is also deposited in use for some time, and medium has the possibility of leakage in the pipe, and the result can cause the water generates in the inner bag to be polluted.
The utility model content
Primary and foremost purpose of the present utility model is: at the shortcoming that above-mentioned prior art exists, it is high and be not easy the compound heat exchange storage-type Teat pump boiler of fouling to propose a kind of heat exchange efficiency.
The further purpose of the utility model is: propose a kind of compound heat exchange storage-type Teat pump boiler that can effectively avoid dielectric leakage.
In order to reach above purpose, compound heat exchange storage-type Teat pump boiler of the present utility model comprises the inner bag with entery and delivery port and the condenser heat-exchange tube of heat pump, and it is characterized in that: described heat-exchange tube constitutes by external section and built-in section; Described external section is fitted in described inner bladder outer wall; Described built-in section is placed in the described inner bag; Described external section with the described built-in section connection of connecting.
The utility model further improves, and when the described external section length setting with built-in section was work, perfect condition was for being steam state heat exchange medium (being mainly the steam state heat exchange medium usually gets final product), formation sensible heat transfer section in described external section; Be vapour-liquid mixed state heat exchange medium in described built-in section, form the condensing heat-exchange section.
During work, the heat exchange medium of heat pump at first enters external section, with water in the inner bag by courage wall indirect heat exchange, enter built-in section after the cooling, with water in the inner bag by the tube wall direct heat transfer.Owing to outside courage, finished sensible heat transfer from the HTHP gaseous state heat transferring medium that compressor is discharged, and then enter and carry out condensing heat-exchange in the courage, therefore reduced the tube wall heat exchange temperature that in inner bag, directly contacts,, significantly reduced fouling having under the situation of higher heat exchange efficiency with water.
In order to reach the further purpose of the utility model, the described built-in section inner and outer pipe with mutual applying has at least one between described interior pipe and the outer tube and leads to the outer drainage trough of inner bag.In case built-in section interior pipe leaks, heat exchange medium will be drawn, and can not pollute the water in the inner bag like this.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the local structure for amplifying schematic diagram in A of the present utility model place.
Fig. 3 is the D-D cross-sectional view of Fig. 2.
The specific embodiment
Embodiment one
A kind of compound heat exchange storage-type Teat pump boiler of present embodiment as shown in Figure 1, the inner bag 1 of water storage comprises water inlet 2 and delivery port (not shown), heat-exchange tube constitutes by external section 3 and built-in section 5, and two ends connect heat pump by air inlet pipe 4 and liquid back pipe 6 respectively.External section 3 by air inlet pipe 4 beginning, from high to main frame around inner bag 1 bottom outer wall, built-in section 5 bottom that is placed in the inner bag 1 coiled shape in the shape of a spiral from bottom to top, end connects liquid back pipe 6.Series connection is communicated with between external section 3 and built-in section 5, be the steam state heat exchange medium in external section when the external section length ratio with built-in section set according to work, be the policy setting of vapour-liquid mixed state heat exchange medium in built-in section, thereby form sensible heat transfer section and condensing heat-exchange section respectively.In the present embodiment, external section length ratio with built-in section be 1: 6 (usually can be: the 5-7 scope) 1.
Therefore and form four between the outer tube 5-2 and lead to the outer drainage trough 5-5 of inner bag 1 as shown in Figures 2 and 3, built-in section 5 inner and outer pipe 5-1 and the 5-2 with mutual applying, the outer surface of interior pipe 5-1 have four grooves that extend vertically.The outer surface of outer tube 5-2 is coated with enamel layer 5-3, and end and inner bag 1 are welded on the inner bag 1 by weld seam C.The expanding end of interior pipe 5-1 inserts external section termination, and B is tightly connected by soldering.
Like this, in case built-in section 5 interior pipe leaks, heat exchange medium 5-4 will be drawn, and can not pollute the water in the inner bag.During work, air inlet pipe feeds the gaseous refrigerant of HTHP, through the sensible heat transfer section, enters the condensing heat-exchange section after the condensation.At last, the cold-producing medium of liquid state enters the throttling arrangement of heat pump through liquid back pipe.
Owing to gaseous refrigerant part outside courage of the HTHP of discharging from compressor has been finished sensible heat transfer, and then the heat exchanger that enters part in the courage carries out condensing heat-exchange, therefore reduce the heat exchange temperature of the inner heat exchanger that directly contacts with water of inner bag, significantly reduced fouling.
Facts have proved, after adopting the composite heat exchanger of present embodiment, compare with the heat exchanger of existing inner bladder outer wall winding pipeline, not only can obviously reduce the possibility that immerses heat exchanger generation fouling in the inner bag, and heat exchanger effectiveness also significantly improves, and also avoided ducted cold-producing medium to leak pollution to water generates simultaneously, therefore possessed the characteristics of omnidistance double wall heat exchange, function admirable, safe and reliable.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
