Heat exchanger unit and heat pump unit

摘要

Problem to be solved: to provide a heat exchanger unit having a small pressure loss in the outer tube, excellent in heat insulation performance and excellent heat efficiency.The first outer tube 12 isEach forms an independent fluid pathAt least two first pipes 12aIt consists of 12B andFirst piping 12a12b isEach of the first piping 12a12b is spirally wound around the outer periphery of the first inner tube 11 in an adjacent stateEach of the first piping 12aInThe second fluid branches and flows.A second outer tubeEach forms an independent fluid pathAt least two second piping 22aConsists of 22b andThe second piping 22a22bEach second piping 22a22b is spirally wound around the outer periphery of the second inner tube 21 in an adjacent stateEach second piping 22aInThe second fluid branches and flows.First heat exchanger 10The second heat exchangerFirst fluid communication part 30And the second fluid communication sectionHoused in one storage container 80.Diagram
