  • Patent number: 10119765
    Abstract: An arc-shaped plate heat exchanger, including a cylindrical housing and a heat-exchanging plate assembly. The heat-exchanging plate assembly includes two groups of arc-shaped heat-exchanging plates symmetrically disposed at either side of the axis of the housing. In each group of the arc-shaped heat-exchanging plate, multiple arc-shaped heat-exchanging plates are arranged from the housing center outward and form isolating first and second fluid channels, the plates' diameters increasing outward. During heat exchange, cold fluid enters the heat exchanger from the housing's first fluid inlet, and flows through straight channels of the arc-shaped heat-exchanging plates to exit from a first fluid outlet, while the hot fluid enters the heat exchanger from a second fluid entrance on the side wall of the housing, and flows through arc-shaped channels of the arc-shaped heat-exchanging plates to exit from a second fluid outlet. Heat exchange between the cold and hot fluid is thus achieved.

  • Patent number: 8439104
    Abstract: Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include multichannel tube configurations designed to reduce refrigerant pressure drop through a heat exchanger manifold. In certain embodiments, tubes inserted within the manifold adjacent to a refrigerant inlet have non-rectangular or recessed end profiles configured to increase flow area near the inlet, thereby reducing a pressure drop through the manifold. In further embodiments, insertion depths of the tubes within the manifold vary based on distance from the inlet. This configuration may establish a larger flow area adjacent to the inlet, thus reducing the pressure drop and increasing heat exchanger efficiency.

  • Patent number: 8240365
    Abstract: It is known that corrugated plate heat exchangers can have good thermal and hydraulic performance but limitations with regard to operational pressures whilst conventional tube type heat exchangers can achieve high pressure operation but can have high flow pressure losses due to the configuration of such tubes. By arranging a tube stack comprising respective tubes 2a, 3a arranged in layers typically one upon the other with cross junctions 4 between them and intersticial gaps between tubes it is possible to create swirling spinning motion in the flow possibly inside and at least outside the tubes for improved heat exchange with only limited flow restriction. The swirling flow in the heat exchanger matrix outside of the tubes passes along channels formed by the interconnecting intersticial gaps between the tubes and is guided about those tubes for heat exchange.

  • Patent number: 7812482
    Abstract: By reviewing a material of a forcer housing and an assembly structure of a coil member with respect to the forcer housing, a thrust force is increased, an optimum shape can be easily given to the forcer housing depending on a purpose of use, and a linear motor can be manufactured at low cost. The linear motor includes a magnet rod composed of a large number of magnetic poles arranged with predetermined pitches along an axial direction and a forcer having a through-hole into which the magnet rod is loosely inserted and reciprocatable relatively to the magnet rod according to an applied electric signal. The forcer is composed of a forcer housing in which the through-hole is defined and a coil member which is arranged on an inner peripheral surface of the through-hole of the forcer housing and to which the electric signal is applied. The forcer housing is formed by mold forming with an insulating nonmetal inorganic material.

    Abstract: A method for forming heat exchanger plates (10) comprises formation of a fluid flow channel (28) along the edges (22) of a sheet metal strip or blank, and formation of a pair of raised end bosses. The raised end bosses (32) are elongated in the longitudinal dimension and are formed within the final width dimension of the plate so as to avoid the need for trimming of excess material along the edges of the plate. The method generates less scrap than prior art processes using progressive stamping, and also permits variation of the plate lengths.

  • Patent number: 7398819
    Abstract: A comb-like insert having a body and plurality of tapered fingers is installed with its fingers disposed within respective minichannels. The fingers and their respective minichannels are so sized as to restrict the channels and frictionally hold the insert in place in one dimension while providing for gaps in another dimension such that the flow of refrigerant is somewhat obstructed but allowed to pass through the gaps between the insert fingers and the minichannel walls and then expand as it passes along the tapered fingers to thereby provide a more homogenous mixture to the individual minichannels. A provision is also made to hold the insert in its installed position by way of internal structure within the inlet manifold. In one embodiment, an internal plate is provided for that purpose, and the plate has openings formed therein for the equalization of pressure on either side thereof.
