EVAPORATOR AND REFRIGERANT CIRCUIT
Document Type and Number:
Japanese Patent JP2018059664
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress lubricant from being accumulated in a header, in a structure including a plurality of heat transfer pipes.SOLUTION: A heat exchanger 10A includes: a plurality of heat transfer pipes 11 that is provided with intervals in a vertical direction, and where refrigerant circulates toward an end part on one side; and a header 20A that extends in the vertical direction, to which the end parts on the one side of the heat transfer pipes 11 are each connected, and where refrigerant circulates from a lower end part 20s toward an upper end part 20t to which a refrigerant pipe 4 is connected. For the header 20A, a flow passage cross sectional area of a portion to which a heat transfer pipe 11A positioned at a lowermost stage among the plurality of heat transfer pipes 11 is made smaller than a flow passage cross sectional area at the upper end part 20t.SELECTED DRAWING: Figure 1
