A tube for a heat exchanger, and more particularly, a tube for a heat exchanger, which has a first reinforcement portion corresponding to a curved section of a tube and a second reinforcement portion attached to the first reinforcement portion formed at both ends of an inner fin so as to increase the strength of both ends in the air flow direction of the tube.

Tube for heat exchanger

The present invention relates to the heat exchangerof refrigerant circuitry of an air-conditioning system for a vehicle, which enables a bidirectional pass flow. The air-conditioning system is configured to perform a combined operation of cooling device mode and heat pump mode, the heat exchangeris formed in the form of a multi-pass, and the flow direction of a refrigerant varies depending on operation mode. The first heat exchangerformed in the form of a multi-pass includes header pipesand, flow paths assigned to respective passes, and means configured to partition an internal volume space of one or more header pipesandinto independent regions. A first pass of the heat exchangerhas a greater flow cross section and greater heat exchange surface than the last pass.

Heat exchanger for refrigerant circuitry

A device for a heat exchanger has a hollow cylindrical header and a plurality of flat tubes. A wall of the header includes a plurality of through openings. The flat tubes are received in the through openings through the wall into the inner cross-section of the header tube, and are aligned with the width of the flat tubes parallel to the direction of the inner dimension. A width of the flat tubes is greater than an inner dimension of the inner cross-section and is smaller than the outer dimension of the header tube, wherein the through openings are embodied as having grooves that continue in the wall of the header tube into the inner cross-section. The flat tubes, which are guided in the through openings through the wall, are arranged in the grooves.
