摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger capable of combining easily a flow passage for water with a flow passage for a refrigerant.
SOLUTION: Header tank parts 23, 24 of the first flat tube 21 are arranged in the same side with respect to a width direction of a plurality of second flat tubes 22. Slots 27a of header tanks 25, 26 are thereby engaged with both end sides of the plurality of second flat tubes 22 to form the flow passage for the refrigerant, and the flow passage for the water is easily combined with the flow passage for the refrigerant, by inserting respective fluid passing parts 21A in the water flow passage layered with the first flat tube 21, between the second flat tubes 22, from a width-directional one side face of the second flat tubes 22. The slots 27a of the header tanks 25, 26 get easy to be engaged with the both end sides of the second flat tubes 22 when engaged, since a positioning jig can be inserted to position the each second flat tube 22 instead of the first flat tube 21, by assembling the flow passage for the water separately from the flow passage for the refrigerant.

摘要： PROBLEM TO BE SOLVED: To secure a space 32 with a prescribed clearance between flat perforated tubes 14 adjacent when the flat perforated tubes 14 are layered along a thickness direction with the same orientation.
SOLUTION: This flat perforated tube 14 for heat exchange formed with a refrigerant passage 141 penetrated along a longitudinal direction in its inside is provided in a flat face with a big protrusion 142 as a function part for securing the space 32 with the prescribed clearance between the flat perforated tubes 14 adjacent when layered along the thickness direction with the same orientation. The big protrusion 142 serves thereby as a role of a spacer when the flat perforated tubes 14 are layered along the thickness direction with the same direction to secure the space 32 with the prescribed clearance between the adjacent flat perforated tubes 14. Dispersion of the tube clearance in manufacturing is thereby restrained to restrain dispersion in heat exchange performance, a pressure loss or the like.

摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger capable of reducing a bias of temperature of a heating medium without increasing pressure loss due to a turn in a flow of the heating medium when heating air conditioned air by using CO
2 as the heating medium in a heat exchanger carrying out only heating of an indoor heat exchanger (a heater core) 3 of an automobile air conditioner.
SOLUTION: The indoor heat exchanger 3 is provided with a front core 4 arranged in an upstream side of an air conditioned air flow, and a rear core 5 arranged in a downstream side in parallel with the front core 4, and the heating medium (CO
2 ) flows from the rear core 5 toward the front core 4. By setting a pitch of fins 52 provided on the rear core 5 more sparse than a pitch of fins 42 provided on the front core 4, a rate of heat transfer quantity of the front core 4 is set larger than a rate of heat transfer quantity of the rear core 5. By this, rapid temperature drop of the heating medium in an inlet vicinity of the rear core 5 can be prevented, and the bias of temperature of the heating medium can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger capable of reducing the weight and the cost thereof by providing an adequate pressure-proof structure.
SOLUTION: The pressure-proof structure against the internal fluid pressure of a header tank 13a or a flat tube 11A in the vicinity of a refrigerant inlet 14 with the refrigerant of carbon dioxide of high temperature and high pressure flowing therefrom is higher than that of header tanks 13b and 13c of other parts or a flat tube 11a. The pressure-proof strength is high only a part in the vicinity of the refrigerant inlet 14 with the refrigerant of high temperature and high pressure flowing therefrom so as to adapt the refrigerant of large temperature difference between an inlet and an outlet such as carbon dioxide. On the other hand, the wall thickness of other parts can be reduced. Therefore, the weight and the cost of the heat exchanger can be reduced.
