Description

Variable flow dividing structure of outdoor heat exchanger Technical Field The utility model relates to the technical field of air conditioner heat exchangers, in particular to a variable flow dividing structure of an outdoor heat exchanger. Background In the design process of the air conditioner, the optimal design of the flow path of the heat exchanger is an important direction for improving the performance of the air conditioner, and the flow path arrangement has a great influence on the performance of the heat exchanger and the whole air conditioner under the condition of determining the size of the air conditioner. When the air conditioner is used for refrigerating, the outdoor heat exchanger is used as a condenser, the less the split is, the better, when the air conditioner heats, the more the outdoor condenser is, the better. The refrigerating and heating operation of the air conditioner is different from the optimal design of the heat exchanger of the outdoor unit, the proper condensation supercooling design is favorable for improving the refrigerating performance of the air conditioner, but is unfavorable for heating, and in order to give consideration to the optimal refrigerating and heating performance of the heat pump air conditioner unit, the design rationality of a system flow path is improved.
