Definitions

  • the present invention relates a heat exchange plate, which is formed of a metallic plate and to be used in combination with the other heat exchange plates having the same structure so that they are combined in parallel and integrally with each other to form a heat exchanger, and especially to such a heat exchange plate that permits to provide an integrally combined state for the heat exchanger in which an appropriate heat exchange can be made between heat exchange fluids under the same heat transfer conditions between them, while causing the heat exchange fluids to flow smoothly along the opposite surfaces of the heat exchange plate, respectively, thus enhancing heat exchange efficiency.
  • a plate-type heat exchanger has conventionally been used widely.
  • the plate-type heat exchanger has a structure in which a plurality of heat transfer plates are placed parallelly one upon another at prescribed intervals so as to form passages, which are separated by means of the respective heat transfer plates.
  • a high temperature fluid and a low temperature fluid flow alternately in the above-mentioned passages to make heat exchange through the respective heat transfer plates.
  • Japanese Patent Provisional Publication No. H3-91695 describes an example of such a conventional plate-type heat exchanger.
  • the conventional plate-type heat exchanger gasket members formed of elastic material are placed between the adjacent two plates to make the distance between them constant and define passages for fluid.
  • a high pressure of the heat exchange fluid flowing between the plates may cause deformation of the gasket member, thus disabling an appropriate separation of the fluids from being ensured or leading to an unfavorable variation in distance between the plates.
  • an effective heat exchange may not be carried out, thus causing a problem.
  • the conventional heat exchanger involves a problem that the heat exchange fluids can be utilized only in a pressure range in which the gasket member withstands.
  • a pattern of irregularity of herringbone type has conventionally and widely applied to the heat transfer plates of the plate-type heat exchanger.
  • a pattern of irregularity could not achieve a balance of decrease in pressure loss and assured resistance to pressure.
  • various kinds of different pattern of irregularities have been proposed.
  • Japanese Patent Provisional Publication No. 2000-257488 describes an example of such different pattern of irregularities.
  • the plates for the above-mentioned conventional heat exchanger has a structure in which the plate includes a plurality of heat transfer sections each of which has a mound configuration provided at its top with a flat portion in a thickness direction of the plate (i.e., a cross section thereof) and a rectangular shape in a plan view of the plate. These plates are combined to each other so as to be placed one upon another to form a single heat exchanger.
  • the conventional heat exchangers (i.e., heat exchange units) have structures as described in Japanese Patent Provisional Publication Nos. H3-91695, 2003-194490 and 2000-257488.
  • the plates are placed one upon another to form a heat exchanger so that alternating plates are turned upside down and upper end portions of heat transfer sections of the plate faces flowing passage-intersections of the adjacent plate.
  • the plates are combined to each other so that the heat transfer sections protrude the same direction, with the result that the flowing passages formed between the adjacent two plates have the same pattern, although the alternating plates are turned by 180 degrees, leading to a reverse positional relationship in a direction perpendicular to the combining direction of the plates.
  • the plate is provided on the lower surface side with the reverse pattern of irregularity to the upper surface side, leading to symmetrical configuration on the opposite surfaces of the plate. Therefore, the same heat transfer conditions cannot been given to fluids on the opposite surfaces of the heat exchange plate, thus making it impossible to cope appropriately with a case in which the heat transfer states between the opposite surfaces of the plate and the respective fluids are kept identical to ensure sufficient heat transfer efficiency between heat exchange fluids.
  • the matching of such a configuration with characteristic property of the respective heat exchange fluids which are brought into contact with the respective surfaces of the plate, or with flowing state thereof makes it possible to enhance independently the heat transfer efficiency between the plate and the respective fluids, so as to improve a general heat exchange efficiency between the fluids, even in case where the heat transfer states on the opposites surfaces of the plate are different from each other.
  • the configuration of the respective plates is specialized for a certain flowing state of each fluid.
  • the heat transfer performance may deviate from the optimum point, thus leading to a severe deterioration in performance and being inferior in general versatility.
