<P>PROBLEM TO BE SOLVED: To provide a structure with which the temperature of a gas-liquid two-phase state can be measured accurately in a device containing a side-flow type parallel-flow heat exchanger. <P>SOLUTION: A heat exchanger 1 includes: two vertical header pipes 2 and 3; a plurality of horizontal flat tubes 4 arranged between the header pipes 2 and 3 and in the interior of which refrigerant passages 5 that communicate with the interiors of the header pipes 2 and 3; and fins 6 arranged between the adjacent flat tubes 4. A thermosensor element 11 for detecting the refrigerant temperature is arranged in the flat tube 4 in which the refrigerant flows in a gas-liquid two-phase state among the plurality of flat tubes 4, or in the fins 6 sandwiched between those flat tubes 4. The flat tubes 4 are structured to form at least two turns, and the flat tubes 4 other than the flat tubes 4 those which form the flow path prior to the first turn and the flow path after the last turn are treated as the flat tubes 4 through which the gas-liquid two-phase refrigerant flows. <P>COPYRIGHT: (C)2013,JPO&INPIT |
