Specific implementation mode
As shown in figure 5, water-heater water tank proposed by the present invention includes inner water tank 4, at least side of inner water tank 4 coats
There is heat exchanger, can select to wrap in the even more sides in one side or both sides according to the concrete shape of inner water tank in actual use
Cover the heat exchanger.
Heat exchanger includes：First header 1, the second header 2 and set of heat exchange tubes, set of heat exchange tubes are alternatively arranged by several
Heat exchanger tube 3 between the first header 1 and the second header 2 is constituted, and one end of heat exchanger tube 3 connect phase with the first header 1
Logical, the other end of heat exchanger tube 3 connect with the second header 2 and communicates.
The inside of first header 1 is in hollow state, and the inside of the second header 2 is also in hollow state, the first header 1
It is equipped with refrigerant inlet 11, the second header 1 is equipped with refrigerant exit 21, and refrigerant enters the first header 1 from refrigerant inlet 11
It flow in heat exchanger tube 3, the refrigerant in heat exchanger tube 3 then flows into the second header 2, is finally flowed out from refrigerant exit 21.In heat exchanger
Refrigerant from the first header to the direction of the second header flow, avoid refrigerant from frequently exchanging heat with external agency, improve exchange heat
The heat exchange efficiency of device.
In a preferred embodiment, the first header 1, the second header 2 and the heat exchanger tube 3 of heat exchanger are respectively positioned in water tank
The same side of courage 4, and the first header 1 is located at the upper lateral part of inner water tank 4, the second header 2 is located at being somebody's turn to do for inner water tank 4
Side lower part, heat exchanger tube 3 are bonded the outer wall of inner water tank 4, and the benefit being arranged in this way is to be conducive to the water temperature delamination of water in water tank, heat exchange
Pipe 3 preferably uses flat tube, the outer wall of the flat horizontal surface fitting inner water tank 4 of flat tube, heat exchange efficiency higher.
As shown in Fig. 6 to 9, the appearance of inner water tank 4 is similar to cylinder, 4 horizontal placement of inner water tank, the first header
1 and second header 2 be of a straight line type, heat exchanger tube 3 is in the arc that is bonded with 4 side of inner water tank.More preferably, inner water tank 4
Front and rear sides be respectively provided with a heat exchanger, two heat exchangers be symmetrical arranged and be connected in parallel, the refrigerant of two heat exchangers
