Heat exchange water tank and water heater

Abstract

The invention provides a heat exchange water tank and a water heater. The heat exchange water tank comprises a liner and a heat exchange part, wherein a first heat exchange area is formed at the upperpart in the liner, and a second heat exchange area is formed at the lower part; and the heat exchange part comprises a first current collecting pipe, a second current collecting pipe and multiple heat exchange pipes. In the heat exchange water tank and the water heater, the first current collecting pipe is arranged in the first heat exchange area, and the second current collecting pipe is arranged in the second heat exchange area; when a refrigerant enters the heat exchange part, the refrigerant exchanges heat with the second heat exchange area after heat exchange with the first heat exchangearea, so that the heat exchange of the refrigerant with the first heat exchange area again after heat exchange with the second heat exchange area can be prevented, and the condensation and heat exchange performance in channel heat exchange is effectively improved; and meanwhile, the first current collecting pipe is arranged on the upper side, and the second current collecting pipe is arranged onthe lower side, so that the flowing direction of the refrigerant and the distribution direction of the water temperature in the liner from low to high are opposite, the countercurrent heat exchange isrealized, and the heat exchange performance is further improved.

Description

technical field [0001] The invention relates to the technical field of air energy heat exchange equipment, in particular to a heat exchange tank and a water heater. Background technique [0002] The air energy water heater uses the reverse Carnot principle to drive the compressor with a part of the electric energy. Through the thermal cycle, it absorbs heat from the low-grade energy (air) in the surrounding environment, sends it to the water tank heat exchanger, and releases it to the water in the water tank. Heating it is a new type, high-efficiency, energy-saving, and environmentally friendly water heater product; at present, the water tank of air-energy water heaters generally uses a single liner, and the heat exchanger mostly uses a micro-channel heat exchanger, which is generally made of It is composed of two collecting pipes and many flat pipes containing micropores. The collecting pipes are installed at both ends of the flat tubes, and the multiple flat tubes are str...
