Title:
HEAT EXCHANGER AND REFRIGERANT DEVICE HAVING HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2019/150852
Kind Code:
A1
Abstract:
In order to inhibit accumulation of a liquid refrigerant, this outdoor heat exchanger (15) has: a heat exchange unit (40) including a plurality of heat transfer tubes (41); a diverter (90); and a plurality of second header internal space forming members (78) that form refrigerant flow passages between the heat exchange unit (40) and the diverter (90). The diverter (90) has: an inlet/outlet tube (91); a plurality of first fine tubes (93); and a diverter body (95) having a body internal space (SP3) that communicates with the inlet/outlet tube (91) and the first fine tubes (93) and allows the refrigerant to flow from one side to the other side. The second header internal space forming members (78) have second header internal spaces (SP1) that communicate with the corresponding heat transfer tubes (41) and first fine tubes (93) and allow the refrigerant to flow from one side to the other side. In an installed state, three of more of the second header internal spaces (SP1) are arranged side by side along the vertical direction, and the number of the heat transfer tubes (41) communicating with a middle-stage second header internal space (SB) is less than the number of the heat transfer tubes (41) communicating with a lower-stage second header internal space (SC).
