Document Type and Number:
WIPO Patent Application WO/2019/215837
Kind Code:
A1
Abstract:
An inflow-side header (3a), into which refrigerant flows from the outside, is provided with: a gas-liquid mixing part (4) provided to an inlet pipe (36) for refrigerant (L), refrigerant in both gas and liquid phases flowing into the gas-liquid mixing part (4); a refrigerant distribution chamber (30) to which heat-transfer pipes (5) are connected in a space outside of the gas-liquid mixing part (4); and the communication pipes (5), which are flat heat-transfer pipes of which one-end side is present in the gas-liquid mixing part (4) and the other-end side is connected to the refrigerant distribution chamber (30). The communication pipes (5) are provided with a plurality of refrigerant flow paths extending in the longitudinal direction. An opening part (52) for taking in refrigerant (L) into the refrigerant flow paths is formed in one-end side in the gas-liquid mixing part (4). A supply hole for supplying the refrigerant (L) to one of the heat-transfer pipes (5), or to a plurality of the heat-transfer pipes (5) that are arranged in a continuous row in parallel directions, passes through the refrigerant flow paths.
