  • Plate type heat exchanger
    Patent number: 6681844
    Abstract: The present invention relates to a plate type heat exchanger having a heat exchange element composed of two plates for exchanging heat between a fluid flowing inside the heat exchange element and a fluid flowing outside the heat exchange element. In the plate type heat exchanger, the two plates (1) have a plurality of depressions (8), and the depressions are brought into contact with and bonded to each other. Peripheral portions of the plates are sealed to form a space in which a fluid flows and constitute a heat exchange element (2) having opening portions (5, 6) at both ends thereof. The heat exchange elements (2) are piled on and bonded to each other so that the opening portions (5, 6) communicate with each other.

  • Absorption refrigerator
    Patent number: 6564572
    Abstract: There is provided an absorption refrigerator comprising a liquid-film type plate heat exchanger structure,. which is improved in terms of installation while maintaining the height of the refrigerator at a practical level. In an absorption refrigerator utilizing a liquid-film type plate heat exchanger for an absorber (A), an evaporator (E), a regenerator (G) and a condenser (C), all the absorber, the evaporator, the regenerator and the condenser, each comprising the liquid-film type plate heat exchanger, are arranged in a horizontal direction. The evaporator, the absorber, the regenerator and the condenser are accommodated in a single can body (1), and the evaporator and the absorber, and the regenerator and the condenser are, respectively, accommodated in different chambers arranged in a lateral direction, which are divided by a partition wall (16) provided in the can body.
