As shown in fig. 1, 2 and 3, an embodiment of the present invention provides a water heater 100, which includes a water tank liner 10, a heat exchange mechanism 20 and a heat conduction structure 30. The heat exchange mechanism 20 is sleeved on the water tank liner 10, and includes a heat exchange pipeline 22 and an anti-drop groove formed on the surface of the heat exchange pipeline 22 facing the water tank liner 10. As shown in fig. 2 or fig. 3, the heat conducting structure 30 is disposed between the tank liner 10 and the heat exchange pipeline 22 and is partially embedded in the anti-drop groove, and is made of yb-ba-cu oxide.
According to an embodiment of the present invention, the water heater 100 replaces the existing heat conducting structure formed by the heat conducting silicone grease by the heat conducting structure 30 formed by the yb-ba-cu oxide, and since the heat conducting efficiency of the yb-ba-cu oxide (the heat conducting coefficient is usually around 6000W/m K) is higher than the heat conducting efficiency of the heat conducting silicone grease (the heat conducting coefficient is usually 1-10W/m K), the heat conducting structure 30 that can be formed by the yb-ba-cu oxide has higher heat conducting efficiency. And since the yb-ba-cu oxide has a characteristic of being not easily aged, the heat conductive structure 30 formed of the yb-ba-cu oxide also has a longer service life. Also, the heat conduction structure 30 formed by the yb-ba-cu oxide has the advantages of higher heat conduction efficiency and longer service life, etc., so that it can greatly improve the heat exchange efficiency between the heat exchange pipeline 22 and the tank liner 10 for a long time, and ensure that the water heater 100 has higher heat efficiency and longer service life. The water heater 100 has the advantages of simple structure, easy assembly, safe and reliable use and convenient implementation, popularization and application.
In this embodiment, heat transfer pipeline 22 includes the flat heat transfer pipe 22a that is parallel to each other and communicates in proper order, all is equipped with at least one anticreep recess that extends along its length direction on every flat heat transfer pipe 22a towards water tank inner container 10's the surface, and every anticreep recess homoenergetic independently holds a heat conduction structure 30. Therefore, each heat exchange flat tube 22a of the heat exchange pipeline 22 can be ensured to be in contact with the water tank liner 10 through at least one heat conduction structure 30, and the heat exchange efficiency between the heat exchange pipeline 22 and the water tank liner 10 is improved more uniformly and comprehensively. It should be noted that, on each flat heat exchange tube 22a, the number of the anti-drop grooves may be one as shown in fig. 2, or may be multiple as shown in fig. 3. When only one anti-falling groove is arranged on each heat exchange flat tube 22a, the length of the anti-falling groove is the same as that of the heat exchange flat tube 22a, but the width of the anti-falling groove is preferably 9/10-19/20 times that of the width of the heat exchange flat tube 22 a. When a plurality of anti-falling grooves are formed in each heat exchange flat tube 22a, the length of each anti-falling groove is equal to that of each heat exchange flat tube 22a, and the sum of the widths of the anti-falling grooves is 1/2-3/4 times that of each heat exchange flat tube 22 a.
In order to improve the heat exchange efficiency between the heat exchange pipeline 22 and the heat conducting structure 30, the fit between the heat conducting structure 30 and the anti-drop groove is preferably an interference fit. More preferably, the cross sections of the heat conducting structure 30 and the anti-dropping groove are rectangular, but the thickness of the heat conducting structure 30 is greater than the depth of the anti-dropping groove, so as to ensure that the heat conducting structure 30 can make better surface contact with the water tank liner 10 and the heat exchange pipeline 22 when the two are in contact with each other.
In this embodiment, the cross section of the tank liner 10 is circular, elliptical, polygonal, or the like.

In this embodiment, the tank liner 10 is made of steel, aluminum, or copper. However, steel is preferred as a material for manufacturing the tank liner 10 because steel has the advantages of low cost, good ductility and good pressure resistance. Preferably, in order to improve the corrosion resistance of the water tank liner 10, an enamel material may be further coated on the surface of the water tank liner 10 to serve as a protective layer. The material for manufacturing the heat exchange pipeline 22 may be steel, aluminum, or copper, but aluminum is preferred as the material for manufacturing the heat exchange pipeline 22 because aluminum has the advantages of low cost, good corrosion resistance, and high heat conduction efficiency.
In the present embodiment, the water heater 100 is an air-powered water heater. The air energy water heater pressurizes and heats a heat exchange medium through a compressor, and then transfers heat to the water tank inner container 10 through the heat exchange pipeline 22 through the heat conduction structure 30, so that water is heated. Heat exchange line 22 is preferably a microchannel heat exchanger.
