PURPOSE:To increase the heat-collection operation efficiency by connecting a plurality of heat-collecting portion by heat collecting medium flowpaths and providing a mixer which amalgamates heat-collecting medium to a heat- collecting medium flowpaths and rebranches the same. CONSTITUTION:A coolant reduced in pressure by an expansion valve 3 flows along heat-collecting medium flowpaths 10 and 10 branched in parallel. Now, provided that external heat-collecting conditions, which are external factors, are locally making contact with respective flowpaths 10 and 10 have the same heat-collecting members in common, and hence the heat-collecting amounts becomes equivalent. Further, the entire heat collection amount are equal in respective heat collection medium flowpaths because a plurality of heat- collecting portions 12, 12... are connected to each other. Then, in a case where branching flow amounts of the coolants flowing through parallel flowpaths 10 and 10 by the internal factors are different from each other, the coolants are amalgamated by a mixer 13 provided on the and rebranched, whereby the difference in the initial branch flow amounts is corrected from the mixer 13 and so on, and hence the heat collector can be effectively used.
