副導管とに接続したことを特徴とする熱交換器。[Claims for Utility Model Registration] A heat exchanger having a heat exchanger main body 11 formed with a fluid passage through which a heat medium such as a refrigerant flows and an air circulation part where heat is exchanged by the heat medium, each having a U-shape. A plurality of pairs of turn passages forming a shape are formed in the heat exchanger body 11 in communication with each other, and fluid is guided to two locations 20 and 21 of a series of passages formed by the entire plurality of pairs of turn passages. A sub-conduit 25 for fluid guidance is connected to at least one of the connecting portions 22 between the turn passages, and the heat is transferred from one end of the series of passages to the other end. A switching means that operates to switch between a continuous turn position in which the medium is circulated and a parallel turn position in which the heat medium is simultaneously circulated from one end of at least two of the turn passages toward the other end of the main conduit and the sub-conduit. A heat exchanger characterized in that it is connected to.
