  • Patent number: 10371464
    Abstract: A tube header for a heat exchanger includes a header plate having two major dimensions defining a header plane. The header plate has a row of oblong passages extending through the header plate. Each passage is bordered by a ferrule monolithically formed with the header plate. The ferrule has a surrounding wall extending perpendicular to the header plane. A transitional area between the ferrule and the header plate has a reduced thickness that is smaller than the wall thickness of the ferrule. This transitional area provides a flexible hinge-like function for compensating dimensional changes during thermal cycles of a heat exchanger.

  • Patent number: 10295167
    Abstract: Novel 3-D super-thermal conducting heat management design and delayed cooling using phase change materials are adopted to lower the temperature inside LEDs and other devices. The cooling mechanism uses a fin structure with hollow fins to dissipate heat to the environment. The hollow space inside the fins is connected to an interior chamber, where a liquid to vapor phase change material (L-V PCM) is provided to transfer heat from the LED chips to the surface of the hollow fins. The LED chips are mounted on an evaporator located at the bottom of the chamber. A liquid reservoir is provided, and the evaporator surface is hydrophilic with an additional wick structure to transport the L-V PCM liquid to the evaporator surface. The fins are parallel to each other and are either parallel or perpendicular to the evaporator surface. This structure has superior performance and is inexpensive to manufacture.

  • Patent number: 9587887
    Abstract: A plate cooler for fluids, such as hydraulic oil, having a parallelepiped-shaped package of plate bodies forming spaced-apart fluid channels and air channels interposed between adjacent plate bodies. The plate bodies communicate on their ends with a fluid channel in a distributor box and a collection box. The distributor and collection boxes have an extruded aluminum profile, a continuous fluid channel, and a ribbed body having lateral ribs with continuous guide grooves for mounting elements and receiving slots for the extruded plate body profile. The fluid channels discharge into a collection chamber, communicating with the continuous fluid channel of the ribbed body. The continuous receiving slots for the plate bodies in the distributor box and in the collection box are configured in circular and conical form, and the inserted plate bodies are connected thereto in fluid-tight fashion in a low-temperature adhesive bonding process.

  • Patent number: 9574806
    Abstract: A heat exchanger includes a plurality of flat tubes, a header collecting tube connected to the flat tubes, and fins joined to the flat tubes. The header collecting tube includes a first partition member partitioning an internal space into upper and lower internal spaces, a second partition member partitioning the upper internal space into first and second spaces, an inflow port formed at a bottom part of the first space, an upper communicating passage, a lower communicating passage. A third partition member partitions the lower internal space into an ascension space and an inflow space. A lower communicating port allows refrigerant to pass from the inflow space to the ascension space. The lower communicating port and the refrigerant passages of the flat tubes that are connected to the lower internal space are arranged so as not to overlap each other as viewed along the longitudinal direction of the flat tubes.

  • Patent number: 9566672
    Abstract: A heat exchanger and a method of manufacturing the same are provided. With the method, a tube may be inserted into a through hole formed in at least one fin coated with a filler metal, and the tube and a fin collar of the at least one fin may be joined through the filler metal by a brazing processing. A flange may not be formed on or at a top of the at least one fin collar, which protrudes vertically from a central longitudinal plane of the at least one fin. The tube may be made of aluminum (Al), and an interval between an outer circumferential surface of the tube and an inner circumferential surface of the fin collar of the at least one fin may be approximately 0.1 mm or less. Accordingly, contact resistance occurring when fabricating a fin-tube heat exchanger using a mechanical tube expansion method may be reduced, and heat transfer performance of the heat exchanger may be improved because grooves formed within the tube may not be deformed.

  • Publication number: 20150129187
    Abstract: In a condenser, an inlet connector to which a refrigerant is supplied is connected to a side wall of a first header. The inlet connector is disposed in the vicinity of an upper end portion of the first header, and is connected to the side wall of the first header through an inclined portion, which is inclined downwardly at a predetermined angle. In addition, when the refrigerant is supplied from the inlet connector into the interior of the first header, the refrigerant is supplied toward a substantially central region in the heightwise direction of the first header through the inclined portion. Therefore, the refrigerant can be made to flow substantially in a uniform manner with respect to a plurality of tubes, which are arranged in parallel in the heightwise direction of the first header, and heat exchange can be carried out.
