In the heat exchanger unit of the heat pump device, the heat exchanger unit includes an air heat exchanger that exchanges heat between air and the refrigerant, and a spirally wound heat medium exchanger that exchanges heat between the heat medium and the refrigerant. The outer circumferential surface of the heat medium exchanger has a conical shape and substantially contacts at least two mutually adjacent inner surfaces of the housing, so that the bottom surface of the heat medium exchanger and the other inner surface of the housing are in contact with each other. A heat exchanger unit for a heat pump device is obtained, which is characterized in that a space for maintenance is provided between the heat exchanger unit and the heat exchanger unit.
