Abstract
The invention belongs to the technical field of heat exchange, and particularly relates to a heat exchanger and a heat pump water heater. The problem that the actual heat exchange area of an existing heat exchanger is reduced due to an invalid heat exchange area, and the heat exchange efficiency is affected is solved. According to the heat pump water heater, a heat exchanger is arranged on the outer side of a water tank of the heat pump water heater and comprises two collector plates and a plurality of micro-channel flat pipes, each collector plate comprises a first layer plate and a second layer plate, the first layer plate is provided with a groove structure and a welding area, and the welding area is welded to the second layer plate; a refrigerant channel is formed by the groove structure and the part, opposite to the groove structure, of the second layer plate, the two ends of the micro-channel flat pipe are welded to the two collector plates respectively, and the micro-channel flat pipe communicates with the refrigerant channel. Due to the double-layer plate structure of the collector plate, the interval between the end of the micro-channel flat pipe and the water tank is reduced, the length of the non-contact micro-channel flat pipe is reduced, the area of an invalid heat exchange area is greatly reduced, the heat exchange area is increased, and the heat exchange efficiency is improved.
Description
technical field [0001] The application belongs to the technical field of heat exchange, and in particular relates to a heat exchanger and a heat pump water heater. Background technique [0002] Heat pump water heater is a device that uses refrigerant to absorb low-temperature heat energy in the air and transfer it to the water tank to make hot water. It has the advantages of energy saving and high efficiency. [0003] combine figure 1 , the heat exchanger of the heat pump water heater is coated on the outside of the water tank 20. The existing heat exchanger includes two headers 10 and several microchannel flat tubes 200 connected with the headers 10, mainly relying on the microchannel flat tubes 200 Contact with the outside of the water tank 20 enables heat exchange. The high-temperature and high-pressure refrigerant enters the heat exchanger, condenses and releases heat, and exchanges heat with the water in the water tank, thereby heating the water in the water tank. ...
