  • Patent number: 8978745
    Abstract: An exhaust gas heat recovery (EGHR) heat exchanger, for recovering waste heat from the hot exhaust gases of an internal combustion engine, having a housing and a cylindrical body disposed within the housing. The cylindrical body defines a central passageway and together with the housing defines an annular passageway for the flow of hot exhaust gases. A bypass means is disposed within the central passageway and adapted to selectively by-pass at least a portion of the exhaust gas from the central passageway to the annular passageway. The EGHR heat exchanger also includes at least one fluid tube extending along a tube axis and having at least one lobe extending the length of the tube thereby defining a lobed tube. The lobed tube is twisted about the tube axis forming a twisted lobed tube which is then coiled about the longitudinal axis within the annular exhaust gas passageway.

  • Patent number: 8944150
    Abstract: A heat dissipating device includes a chamber with an evaporation portion and a condensation portion, the chamber including a refrigerant. The chamber further includes an evaporation portion scraping brush provided corresponding to the evaporation portion, the evaporation portion scraping brush being able to sweep relative to an inner surface of the evaporation portion. A refrigerant liquid film is formed on the inner surface of the evaporation portion. Since the fluid refrigerant is uniformly applied to an inner surface of the evaporation portion to form a liquid film, the heat dissipating ability of the heat pipe heat dissipating device is improved, and the heat dissipating uniformity of the heat pipe heat dissipating device is enhanced. A heat dissipating method is also provided.

    Abstract: Vapor flow-diverting devices that re-direct upwardly flowing vapor, for example, in a downward direction across condenser tubes disposed in the upper or top section of a vapor-liquid contacting apparatus, are described. These devices are particularly beneficial in tubular condensers within distillation columns and may be used in combination with other associated equipment (e.g., a deflector plate and divider plate) as well as in combination with the tube surface enhancements to improve the heat transfer coefficient.

    Abstract: A chill mold is used to cool molten material to form a casting. A support holds the chill mold so that a bottom of the chill mold is elevated. A baffle is arranged to divert a generally horizontal flow of cooling air upwardly to impinge the bottom of the chill mold. A plurality of chill molds may be aligned generally in a row, and at least one fan may be arranged at an end of the row to direct the flow of cooling air underneath the chill molds. The size and the vertical position of the baffles may be varied along the row, so as to generally equalize convective cooling rates among the chill molds in the row.

  • Patent number: 8894367
    Abstract: Multi-scale turbulation features, including first turbulators (46, 48) on a cooling surface (44), and smaller turbulators (52, 54, 58, 62) on the first turbulators. The first turbulators may be formed between larger turbulators (50). The first turbulators may be alternating ridges (46) and valleys (48). The smaller turbulators may be concave surface features such as dimples (62) and grooves (54), and/or convex surface features such as bumps (58) and smaller ridges (52). An embodiment with convex turbulators (52, 58) in the valleys (48) and concave turbulators (54, 62) on the ridges (46) increases the cooling surface area, reduces boundary layer separation, avoids coolant shadowing and stagnation, and reduces component mass.
