Abstract
A heat exchanger passage switching device according to an embodiment includes: a communication tube having an internal passage communicating with a heat exchange passage for performing heat exchange inside a heat exchanger, and one or more communication holes communicating with the internal passage; and at least one chamber having an insertion hole into which the communication tube is inserted to slidably support the communication tube inserted in the insertion hole. The communication tube is capable of switching a communication state between the one or more communication holes and the at least one chamber by a relative position of the communication tube to the at least one chamber in an axial direction.
