The present invention relates to a cold reserving heat exchanger, and more particularly; to a cold reserving heat exchanger capable of improving cooling comfortableness of a user and minimizing energy and a time consumed at the time of again performing cooling by storing a cold reserving material in a second-row tube among tubes disposed in three rows in a width direction and allowing a cooling fluid moving in a first-row tube and a third-row tube among the tubes to be movable between the first-row tube and the third-row tube to effectively store cold air of the cooling fluid and discharge the cold air at the time of stopping an engine to thus prevent a rapid rise in an internal temperature of a vehicle.

An evaporator for an air conditioning system includes a plurality of clamshell plates stacked in series along a longitudinal axis and a plurality of core tubes coupled with the stacked clamshell plates. In an upper region of the evaporator, the stacked clamshell plates form an inlet tank and an outlet tank hydraulically communicated with the core tubes for a refrigerant flow. Each of the clamshell plates includes a pooling ridge on a first surface of the clamshell plate for pooling a liquid refrigerant by gravity such that the liquid refrigerant is evenly distributed to inlet core tubes disposed along the longitudinal axis.

An improved indirect heat exchanger is provided which is comprised of a plurality of coil circuits, with each coil circuit comprised of an indirect heat exchange section tube run or plate. Each tube run or plate has at least one change in its geometric shape or may have a progressive change in its geometric shape proceeding from the inlet to the outlet of the circuit. The change in geometric shape along the circuit length allows simultaneously balancing of the external airflow, internal heat transfer coefficients, internal fluid side pressure drop, cross sectional area and heat transfer surface area to optimize heat transfer.

A heat exchanging apparatus includes one inflow channel having an inflow port via which a liquid refrigerant flows in, one outflow channel having an outflow port via which the liquid refrigerant flowing through the outflow channel flows out, and a plurality of channels arranged in a flow direction of the liquid refrigerant flowing through the inflow channel, the plurality of channels connecting the inflow channel the outflow channel and causing the liquid refrigerant flowing from the inflow channel to flow into the outflow channel. The plurality channels are connected to the inflow channel over a portion from the inflow port to a terminal end of the inflow channel. The inflow channel includes a buffer section disposed between the inflow port and the terminal end, the buffer section configured no reduce a flow rate of the liquid refrigerant flowing through the inflow channel.

The invention relates to a tube (1) for a heat exchange bundle (100) of a vehicle heat exchanger, said tube (1) comprising: two circulation plates (3) configured to be assembled together in a sealed manner and to form at least one conduit (31) in which a first heat transfer fluid circulates between said circulation plates (3), at least one reservoir plate (5) comprising cavities (51), said reservoir plate (5) being configured to be assembled in a sealed manner on a face of one of the two circulation plates (3) so as to close the cavities (51), the cavities (51) being projections on the face of the reservoir plate (5) such that a second heat transfer fluid can circulate between the cavities (51), the tube (1) further containing a phase change material stored in the housings formed by the cavities (51), the phase change material having a solidification temperature between 6 and 8 degrees Celsius.

Mg and Bi are contained in each of a first fillet in a first braze joining portion in which a tube and a fin join, a second fillet in a second braze joining portion in which the tube and a header plate join, and a third fillet in a third braze joining portion in which the header plate and a tank body join. A concentration of Mg of each of the first to third fillets is from 0.2% or more to 2.0% or less by mass. When the tube includes a brazing material layer, a concentration of Mg of the tube at its plate thickness center is from 0.1% or more to 1.0% or less by mass. When the fin includes a brazing material layer, a concentration of Mg of the fin at its plate thickness center is from 0.2% or more to 1.0% or less by mass.

A stacked heat exchanger includes a first passage tube and a second passage tube that are included in a plurality of passage tubes stacked in a stacking direction. The first passage tube has a first projecting pipe, and the second passage tube has a second projecting pipe. The second projecting pipe has a fitted portion fitted into an inner side of the first projecting pipe, and is connected to the first projecting pipe such that the refrigerant can flow therethrough. The first projecting pipe has a joined portion joined to the fitted portion on a radially outer side of the fitted portion. The joined portion has an outer circumferential surface and an end of the first projecting pipe. The outer circumferential surface of the joined portion extends in the stacking direction to the end along an outer circumferential surface of the fitted portion.

A vehicle heat exchange apparatus, including: a heat-exchanger provided rearward of a front-bumper formed with an air-intake-port, and having an air-inlet-member on a front-face of the heat-exchanger; and a passage-forming-member provided between the front-bumper and the heat-exchanger, and forming a passage for passing cooling-air from the air-intake-port of the front-bumper to the air-inlet-member of the heat-exchanger, wherein the heat-exchanger is provided inclined so that an upper-end-portion is positioned rearward of a lower-end-portion, the passage-forming-member has: a duct-member having: a top-member; a bottom-member facing the top-member; and a pair of side-members interconnecting the top-member and the bottom-member, and forming a part of the passage with a space enclosed by the top-member, the bottom-member and the pair of side-members; and a closing-member provided to close a gap between the top-member of the duct-member and the upper-end-portion of the heat-exchanger.

A heat exchanger includes: heat transfer tubes aligned with one another; a header connected to end portions of the heat transfer tubes; and fins joined to the heat transfer tubes. When viewed in a longitudinal direction of the header and when the heat exchanger is used as an evaporator, the header is divided into: a circulation space including a first space in which refrigerant flows in a first direction along the longitudinal direction of the header and a second space in which the refrigerant flows in a second direction opposite to the first direction along the longitudinal direction; and an insertion space into which the heat transfer tubes are inserted. The header includes: a circulation division plate that divides the first space from the second space; and an insertion space forming plate that divides the circulation space from the insertion space.
