Title:
REFRIGERANT DISTRIBUTER, HEAT EXCHANGER, HEAT EXCHANGER UNIT, AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/005682
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain a refrigerant distributer, a heat exchanger, a heat exchanger unit, and a refrigeration cycle device that are capable of suppressing imbalance in the distribution of refrigerant to heat exchanger tubes in relation to a change in refrigerant dryness or refrigerant flow rate that is dependent on the operation state of the refrigeration cycle device. The refrigerant distributer, heat exchanger, heat exchanger unit, and refrigeration cycle device according to the present invention comprise a first refrigerant inlet, a second refrigerant inlet, a plurality of merging parts disposed spaced apart from each other in a first direction, a first dividing flow path that extends in the first direction and distributes the refrigerant having flowed in from the first refrigerant inlet to the plurality of merging parts, and a second dividing flow path that extends in the first direction and distributes the refrigerant having flowed in from the second refrigerant inlet to the plurality of merging parts. The first dividing flow path includes a first flow path part which extends in the first direction and through which a refrigerant flows, and a plurality of first flow path holes which are formed at positions corresponding to the plurality of merging parts and allow communication between the first flow path part and the plurality of merging parts. The second dividing flow path includes a second flow path part which extends in the first direction and through which a refrigerant flows, and a plurality of second flow path holes which are formed at positions corresponding to the plurality of merging parts and allow communication between the second flow path part and the plurality of merging parts. The plurality of first flow path holes include a third flow path hole that connects to a first merging part which is one of the plurality of merging parts. The plurality of second flow path holes include a fourth flow path hole that connects to the first merging part. The path length from the first refrigerant inlet to the third flow path hole is different from the path length from the second refrigerant inlet to the fourth flow path hole.
