  • Patent number: 8596089
    Abstract: A refrigerant distribution system has a plurality of chambers formed inside a refrigerant distribution plate, each of the plurality of chambers extending from one end of the refrigerant distribution plate into the refrigerant distribution plate; and a plurality of holes formed in each of the plurality of chambers, the plurality of holes fluidly communicating each of the plurality of chambers with an outside of the refrigerant distribution place. The evaporator may be oriented such that the refrigerant flows horizontally with respect to gravity. The present invention may improve the thermal performance of the evaporator while the evaporator is oriented sub-optimally. Often, with horizontal flow through an evaporator, the refrigerant phases, liquid and vapor, may separate in the manifold, resulting in poor distribution of refrigerant in the evaporator core. The refrigerant distribution plate of the present invention evenly distributes the refrigerant in the core.

  • Patent number: 8596339
    Abstract: A manifold structure is defined by a pair of stacked plates which define a void: one of these plates has three or more aperture-surrounding bosses which project into the void; the other of these plates has a plurality of protuberances. Each of the protuberances engages between a respective pair of the bosses. A heat exchange element is formed of a plurality of stacked plates, these plates defining a stack of tubes. The tube stack interiorly defines a plurality of U-shaped passages, these passages being distinct from one another. Each tube defines a respective one of the U-shaped passages and is received in plug-fit relation by a respective one of the bosses. The tubes, bosses and protuberances separate the void into a pair of manifolds. Each of the U-shaped passages leads from one of the manifolds to the other of the manifolds.

    Abstract: A heat exchanger includes a tube with a heat-exchange passage and an end piece. The heat-exchange passage directs the flow of a first medium and includes a first flow section and a second flow section arranged in parallel. The end piece has a tube plate that includes a base plate, a diverter plate, and a cover plate. An end of the tube connects to the base plate. The diverter plate has a cutout that forms a diverter passage. The cover plate lies adjacent to the diverter plate and covers the diverter passage in a fluid-tight manner. A second medium flows exterior to the heat-exchange passage.

  • Patent number: 8528629
    Abstract: The invention relates to a heat exchanger (e.g., a charge air cooler) having a cooling body composed of flat tubes arranged at intervals and having corrugated fins positioned in the intervals. The charge air in the flat tubes can be cooled by cooling air flowing through the corrugated fins. The heat exchanger can include a flow connector and an integrated pre-cooler in which a medium, for example charge air, is cooled by means of a coolant. The pre-cooler/post cooler can be integrated into a section of the cooling body. A flow connector composed of at least two tubular parts which can be plugged one into the other, locked and sealed, can include a partitioning wall extending in one of the parts. At least one inlet connection and/or at least one outlet connection can be arranged on one or the other of the parts.
