Abstract
A spiral heat exchanger includes a spiral unit, a case member, and a bracket. The spiral unit includes thin metal plates. The thin metal plates are spaced away from each other and spirally wound. The thin metal plates define flow paths. A portion or all of the flow paths are provided with a coolant flowing therein. The case member is attached to a vehicle and contains the spiral unit. The bracket is fixed to the case member and holds the spiral unit. The bracket includes a holding portion and a fixed portion. The holding portion holds a first end, a second end, or both of the spiral unit in an axial direction. The fixed portion is disposed between an outer peripheral surface of the spiral unit and an inner peripheral surface of the case member. The fixed portion is fixed to the inner peripheral surface of the case member.
