Title:
HEAT EXCHANGER AND HEAT PUMP TYPE REFRIGERATION CYCLE USING THE SAME
Document Type and Number:
Japanese Patent JP2020190378
Kind Code:
A
Abstract:
To provide a heat exchanger that is suitably used as an outdoor heat exchanger of a heat pump type refrigeration cycle, and can restrain an increase in pressure loss and a decrease in heat exchange performance at the time of cooling and heating.SOLUTION: A first header tank 31 of an outdoor heat exchanger 4 of a heat pump type refrigeration cycle 1 comprises a first header part 38 into which a refrigerant flows through a refrigerant inlet 36, and a second header part 39 adjacent to the first header part 38. A second header tank 32 comprises a third header part 41 to which heat exchange pipes 33 leading to the first header part 38 and the second header part 39 lead. A movable partition member 43 separating the first header part 38 and the second header part 39 is arranged between the header parts 38 and 39 so as to be movable in a longitudinal direction of the first header tank 31. The movable partition member 43 moves in the longitudinal direction of the first header tank 31, and thereby the number of the heat exchange pipes 33 leading to the first header part 38 and the second header part 39 is changed.SELECTED DRAWING: Figure 2
