Abstract

The invention relates to a heat storage water tank. The heat storage water tank comprises a shell, a heat exchange assembly and a heat storage assembly. The heat exchange assembly comprises a heat exchange pipeline. The heat exchange pipeline and the heat storage assembly are both arranged in an inner cavity formed by the shell. According to the heat storage water tank, a tube and shell type heat exchanger is adopted, and the heat storage water tank and the heat exchanger are integrated, so that the size of the heat storage water tank is reduced. Meanwhile, a corrugated baffle plate is adopted, so that the heat exchange coefficient between water and heat storage materials is increased. Meanwhile, as the heat exchange area is increased, the heat releasing speed of the heat storage materials is greatly improved. The heat storage water tank further has the characteristic that the shell and tube type heat exchanger has high pressure bearing capacity.

Description

technical field

[0001] The invention relates to the related technical field of heat pump water heaters, in particular to a heat storage tank and a heat pump water heater. Background technique

[0002] Most of the heat storage tanks of existing heat pump water heaters are large in size, such as 200L, 150L, ​​etc., which brings a lot of inconvenience to the installation, and the water tank is very heavy and inconvenient to be placed on the external wall of the building, especially in the building that has been renovated , often give up the use of such energy-saving and environmentally friendly products because of the volume and weight of the water tank.

[0003] Regenerative materials are widely used in industrial heat exchange due to their excellent heat storage performance, but their slow heat release rate is currently the biggest problem in the application of heat storage materials in small products, so most traditional regenerative heat exchangers are bulky Larger, poor h...
