Abstract: A thermomagnetic cycle device includes: a magneto-caloric element; a magnetic field modulation device that modulates an external magnetic field applied to the magneto-caloric element; a heat transport device that generates a both-way flow of heat transport medium; a phase controller that adjusts a phase difference between a magnetic field phase of change in the external magnetic field generated by the magnetic field modulation device and a flow phase of the both-way flow generated by the heat transport device; and a control device that controls the phase controller. The control device includes: a phase acquisition part that acquires the flow phase of the both-way flow of the heat transport medium or a reaction phase represented by change in heat emitted or absorbed by the magneto-caloric element; and a control part that controls the phase controller based on the flow phase or the reaction phase.

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.
