A heat exchanger includes a pipe made of aluminum, a thermistor, and an attaching portion with which the thermistor is attached to the pipe. The pipe carries a flow of refrigerant. The thermistor detects a temperature of the refrigerant. The pipe includes a sacrificial layer provided on a part of a surface of the pipe. The sacrificial layer is lower in potential than the aluminum of the pipe. The attaching portion is higher in potential than the sacrificial layer. At least one part of the attaching portion is attached to the surface of the pipe where the sacrificial layer is not provided. The attaching portion includes a brazed portion that is higher in potential than the sacrificial layer. The thermistor is attached to the pipe with the brazed portion.

Heat exchanger, indoor unit for air-conditioner, and refrigeration device

A heat exchanger includes: a main body; and a tube sheet that is bonded to the main body with a brazing material and is used to fix the main body to a support by a fixing member. The tube sheet includes: a bonding surface to which the brazing material is applied; a rising portion that rises from the bonding surface; and a through-hole through which the fixing member is passed. The through-hole is opened at the rising portion, penetrates the tube sheet, and has an inner peripheral surface to which the brazing material is not applied. The main body includes heat transfer tubes through which refrigerant flows, and the tube sheet is bonded to surface of the heat transfer tube.

Heat exchanger

A refrigeration apparatus includes: a casing that includes first and second spaces; a heat exchanger housed in the casing and including a heat exchange portion and a header collecting tube. The heat exchange portion includes a plurality of heat transfer tubes through which a refrigerant flows, is disposed in the first space, and causes the refrigerant to exchange heat with an air flow. The header collecting tube is connected to the heat transfer tubes and disposed in the second space. The refrigeration apparatus also includes a wind shielding plate including a wind shielding surface that shields the second space from the air flow, where the header collecting tube includes a header body portion that extends in a longitudinal direction of the header collecting tube, and the wind shielding plate is fixed to the header collecting tube and fixed to the casing or a component disposed in the casing.
