Title:
A heat exchanger and a refrigerating cycle device using the heat exchanger
Document Type and Number:
Japanese Patent JP6214670
Kind Code:
B2
Abstract:
An object of the invention is to provide a heat exchanger capable of reducing an amount of refrigerant stagnated in heat-transfer tubes and decreasing a pressure loss in heat-transfer tubes of the heat exchangers as a whole. A heat exchanger including a first heat exchanger 101 disposed on upstream side of a heat exchange fluid and a second heat exchanger 102 disposed on downstream side of the heat exchange fluid, which are connected in series in a flow path of a heat medium, wherein the heat medium flows from the first heat exchanger 101 to the second heat exchanger 102 so as to be parallel to the flow of the heat exchange fluid when the heat exchanger serves as an evaporator, the heat medium flows from the second heat exchanger 102 to the first heat exchanger 101 so as to be opposed to the flow of the heat exchange fluid when the heat exchanger serves as a condenser, and a sum of flow path volume of first heat-transfer tubes of the first heat exchanger 101 is smaller than a sum of flow path volume of second heat-transfer tubes of the second heat exchanger.
