Abstract

The utility model discloses an air source heat pump water heater, which comprises a condenser, wherein the condenser is formed by a heat exchange water pipe and a coolant passage. The air source heat pump water heater is characterized in that the heat exchange water pipe has a spiral shape and is arranged inside the coolant passage; the coolant passage is formed by a cylindrical shell, an inner cylinder with an upper opening and a lower opening and a coolant conduit, the upper end and the lower end of the inner cylinder are respectively and fixedly connected with the upper bottom and the lower bottom of the cylindrical shell, the joints are sealed, the upper end of the cylindrical shell is provided with an air intake, the lower end of the inner cylinder is provided with an air lead port, and the coolant conduit extends into the lower part of the inner cylinder from the top of the cylindrical shell; and the heat exchange water pipe is sleeved on the inner cylinder and is positioned between the cylindrical shell and the inner cylinder.With the structure, the water air source heat pump water heater conveys water in the heat exchange water pipe, conveys coolant outside the heat exchange water pipe, is difficult to be corroded, overcomes the defect that the coolant passage is scaled in the prior art, and increases heat exchange area and improves heat exchange efficiency due to the fact that the heat exchange water pipe is wrapped by the coolant. So the water air source heat pump water heater can effectively prevent scaling and has high heat exchange efficiency.

Description

Air source hot pump water heater
Technical field
The utility model relates to a kind of air source hot pump water heater.
Background technology
Present prior art, as shown in Figure 5, air source hot pump water heater comprises condenser, evaporimeter, compressor, expansion valve, described condenser comprises water pipe 1, refrigerant passage 2, refrigerant passage 2 is installed in the water pipe 1, also stretch out from water pipe 1 at two ends, and water inlet, delivery port are arranged on the water pipe 1, and refrigerant import, refrigerant exit are arranged on the refrigerant passage 2.Existing problems are: in the long-term immersion of refrigerant passage, and scaling on the refrigerant passage outer wall, if water quality is bad, also corrosion easily influences heat exchange effect and service life.
Summary of the invention
The purpose of this utility model is: a kind of air source hot pump water heater is provided, and it can prevent the heat exchanging water pipe's scaling in the condenser effectively, and the heat exchanger effectiveness height.
The utility model is achieved in that a kind of air source hot pump water heater comprises condenser, and condenser is made of heat exchanging water pipe, refrigerant passage, and its special character is: described heat exchanging water pipe is positioned at refrigerant passage twist, and refrigerant passage is stretched out at the water pipe two ends; Described refrigerant passage is by cylindrical outer casing, inner core and refrigerant conduit with upper and lower opening constitute, the inner core upper and lower end is fixedly connected with the upper and lower end of cylindrical outer casing respectively and seals, the upper end of cylindrical outer casing has the lower end of air inlet, inner core that air guide port is arranged, and the refrigerant conduit stretches into the inner core bottom by the cylinder shell top; The heat exchanging water pipe is enclosed within on the inner core, between cylindrical outer casing and inner core.
Described air source hot pump water heater, its special character is: described heat exchanging water pipe has fin for outer surface, and inner surface has screw thread.
A kind of air source hot pump water heater of the utility model owing to adopt such structure, is leaked water in the heat exchanging water pipe, walks refrigerant outside the pipe, and is not perishable; Overcome in the prior art the incrusted defective of refrigerant passage; Refrigerant parcel heat exchanging water pipe increases heat exchange area, has improved heat exchange efficiency.So it can prevent scaling effectively, and the heat exchanger effectiveness height.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of air source hot pump water heater comprises condenser, and condenser is made of heat exchanging water pipe 1, refrigerant passage 2, and described heat exchanging water pipe 1 is positioned at refrigerant passage 2 twist, and refrigerant passage 2 is stretched out at water pipe 1 two ends; Delivery port 12 is positioned at the top of refrigerant passage 2, and water inlet 11 is positioned at the bottom of refrigerant passage 2.As shown in Figure 3, Figure 4, described refrigerant passage 2 is by cylindrical outer casing 21, inner core 22 and refrigerant conduit 23 with upper and lower opening constitute, inner core 22 upper and lower ends are fixedly connected with the upper and lower end of cylindrical outer casing 21 respectively and seal, the upper end of cylindrical outer casing 21 has the lower end of air inlet 211, inner core 22 that air guide port 221 is arranged, and refrigerant conduit 23 stretches into inner core 22 bottoms by cylinder shell 21 tops; Heat exchanging water pipe 1 is enclosed within on the inner core 22, between cylindrical outer casing 21 and inner core 22.
Described heat exchanging water pipe 1 is for outer surface has fin, and inner surface has screw thread, has realized bigger heat exchange area in less space;
Refrigerant is entered between cylindrical outer casing 21, the inner core 22 by air inlet 211, and the air guide port 221 through inner core 22 bottoms enters in the inner core 22, after refrigerant conduit 23 is discharged refrigerant passage 2.
