[0002] Usually, a heat pump water heater heats the water inside the water tank through heat exchange between the water tank and the coil. The important indicators that determine the heat exchange effect in the heat exchange process are: heat exchange form, contact area, and the inlet and outlet temperatures of the two heat exchange fluids. When the heat exchange form is certain, increasing the contact area and adjusting the inlet and outlet temperatures of the fluid become the main solutions to improve the heat exchange effect.

[0003] At present, the coil water tank in the industry generally winds a single or double-circuit larger diameter coil (generally above ф7) around the inner tank of the water tank. This has the following problems: since the diameter of the copper tube is relatively thick, and the contact area between the copper tube and the inner tank accounts for a small proportion of the outer surface area of ​​the copper tube, the copper tube utilization rate is low, the heat transfer coefficient is low, and it is not environmentally friendly.
