Abstract: A heat exchanger includes a core portion including a plurality of tubes, and header tanks located on opposite ends in the longitudinal direction of the plurality of tubes and communicate with the plurality of tubes. A first fluid flows through a first tank chamber and a first tube group of the plurality of tubes. A second fluid different in temperature range from the first fluid flows through a second tank chamber and a second tube group of the plurality of tubes connected to the second tank chamber. The heat exchanger includes a flow rate limiting portion. The flow rate limiting portion is configured to reduce a flow rate of the first fluid or the second fluid supplied to at least first one tube of the plurality of tubes from a boundary portion provided by the partition wall.

Abstract: A thermomagnetic cycle device has a plurality of element beds including a magneto-caloric effect element that demonstrates a magneto-caloric effect. A magnetic field modulation device modulates a magnetic field applied to the magneto-caloric effect element. A heat transport device generates a reciprocating flow of a heat transport medium which performs heat-exchange with the magneto-caloric effect element. A variable flow path mechanism activates a part of the plurality of element beds and deactivates a remaining part. A controller determines an active bed number according to a required capacity. The active element bed is arranged to suppress torque fluctuations.
