Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a heat exchange mechanism for an air source heat pump hot water unit comprises an isolation cover 1 and a water tank 2, wherein a mineral cotton layer 7 is embedded in the isolation cover 1 to reduce heat loss, four corners of the bottom of the isolation cover 1 are welded with fixing plates 11 through supporting legs 10, the fixing plates 11 are provided with threaded holes 12 which are convenient to fix, the top ends of the threaded holes 12 are communicated with a circular groove 13, the bottom of the circular groove 13 is glued with an elastic rubber gasket 14, the elastic rubber gasket 14 is arranged to enhance bolt tightening strength, supporting columns 3 at four corners of the bottom of the water tank 2 are welded with the bottom of the isolation cover 1, an inner container of the water tank 2 is made of SUS304 chrome-nickel alloy stainless steel, the top of the water tank 2 is communicated with a water inlet pipe;
the heat exchange tube 4 is wound on the outer wall of the water tank 2, the heat exchange tube 4 is a copper tube, the outer wall of the heat exchange tube 4 is sleeved with the fixing sleeve 17, the fixing sleeve 17 is welded on the outer wall of the water tank 2 to assist in fixing the heat exchange tube 4, the heat exchange tube 4 is provided with the heat dissipation fins 5, the water tank 2 is correspondingly provided with the heat conduction grooves 6, the heat dissipation fins 5 are positioned in the heat conduction grooves 6, the contact area between the heat dissipation fins 5 and the outer wall of the water tank;
