Definitions

  • the present invention relates to a plate heat exchanger, and more particularly to a plate heat exchanger for exchanging heat between two fluids flowing alternately through adjacent fluid passages between piled plates, which is suitable for such cases where at least one of the fluids is a low-pressure vapor, or is evaporated with phase change, or is condensed from a vapor, as an evaporator, a low-temperature generator, or a condenser in a refrigerating machine using a low-pressure refrigerant.
  • FIGS. 10A and 10B are schematic views showing a conventional plate heat exchanger, FIG. 10A is a front view, and FIG. 10B is a side view.
  • FIG. 11 is an exploded explanatory view of FIGS. 10A and 10B.
  • FIGS. 10A, 10B and 11 two plates 3 having opening portions 5 at both ends thereof are piled on each other to form a space therebetween, and the peripheral portions of the plates 3 are sealed to form a heat exchange element 2.
  • the heat exchange elements 2 are piled on and combined with each other in such a state that the opening portions 5 of the plates 3 communicate with each other, thereby producing a heat exchange structure.
  • This heat exchange structure is housed in a shell 20, and fluids flow through the interior and the exterior of the heat exchange elements 2 so as to exchange heat with each other.
  • Such a conventional plate heat exchanger requires not only heat exchange elements composed of plates, but also a shell. Thus, such a conventional plate heat exchanger has been problematic in that manufacturing procedure is complicated and various types of components are required.
  • FIG. 12 shows an example of an absorber and an evaporator utilizing conventional plate heat exchangers.
  • an evaporator 21 and an absorber 22 are disposed on the left side and the right side, respectively.
  • Plate heat exchangers for the evaporator and the absorber have been manufactured separately, and the absorber and the evaporator are different from each other in shape.
  • Many types of components are used for the absorber and the evaporator, and many man-hours are needed to manufacture the absorber and the evaporator.
  • the present invention has been made in view of the above drawbacks. It is therefore an object of the present invention to provide a plate heat exchanger which can easily be manufactured and assembled with a small number of components, can achieve a cost reduction and compactness, and has a high heat exchanging performance.

  • an inlet and an outlet for the second fluid may be provided on a surface of the plate at positions other than the opening portions at the both ends constituting an inlet and an outlet for the first fluid.
  • Two plate heat exchangers described above may be arranged in parallel in a direction of piling of the heat exchange elements, and the passages for the second fluid in the two plate heat exchangers communicate with each other so that a vapor is generated from one of the plate heat exchangers, and condensed or absorbed by the other of the plate heat exchangers.
  • passages curved by projections and depressions are formed inside and outside of heat exchange elements composed of one or two types of components, and the external passages can be formed at a time without use of a shell.
  • a complicated plate heat exchanger for exchanging heat between two fluids having different temperatures can be manufactured at low cost from a small number of components by a simple manufacturing process.
  • a plate heat exchanger characterized in that: a plurality of heat exchange elements are provided, each of the heat exchange elements being composed of two plates opposed to each other as a set, sealed spaces being provided as two systems inside of the two plates, each of the heat exchange elements having two opening portions as an inlet and an outlet for each of the systems; and different fluids flow through internal spaces in the two systems and through passages outside of the internal spaces, respectively.
  • the plurality of the heat exchange elements may be constructed such that the heat exchange elements adjacent to each other communicate with each other, and have peripheral portions which are brought into contact with each other and sealed therebetween.
  • the internal spaces in the two systems may be arranged on a right side and a left side, and portions of communication between the plurality of the heat exchange elements are divided into a plurality of segments in a vertical direction.
  • a plate heat exchanger characterized in that: a plurality of heat exchange elements are provided, each of the heat exchange elements being composed of two plates opposed to each other as a set, sealed spaces being provided as four systems inside of the two plates, each of the heat exchange elements having two opening portions as an inlet and an outlet for each of the systems; among the four systems, a set of a first system and a second system and a set of a third system and a fourth system are arranged on a right side and a left side, respectively; and different fluids flow through internal spaces in the four systems and through passages outside of the internal spaces, respectively.
  • the plurality of the heat exchange elements may be constructed such that the heat exchange elements, adjacent to each other, outside of the set of the first system and the second system and the set of the third system and the fourth system arranged on a right side and a left side communicate with each other, and the peripheral portions of the heat exchange elements adjacent to each other may be brought into contact with each other and sealed therebetween.
  • a single plate heat exchanger can perform two or four types of heat exchange.
  • a fluid flows as a liquid film on an outer surface of the first system, and is heated by the internal fluid, thereby generating a vapor from the liquid film.
  • the second system is utilized for an absorber, the vapor is cooled by the internal fluid, and can hence be condensed on the outer surface of the second system.
  • an absorption solution flows as a liquid film on the outer surface, whereby the vapor can be absorbed.
  • a plate heat exchanger according to a first embodiment of the present invention will be described below in detail.
  • a plate having a shape suitable for meeting the following conditions can be used: Two plates having projections and depressions are piled on each other to form a space therebetween. When the peripheral portions of the two plates are simply piled, the plates are brought into light contact (i.e., line contact) with each other along the whole peripheries. When a force in a direction of piling is increased, the contacting portions are changed in shape to be brought into surface contact with each other. When the force is increased until the projections and depressions of the respective plates are brought into contact with each other, the area of the contact surface is increased, and hence the peripheries of the plates can be sealed by brazing.
  • the present invention can be applied to not only a case of brazing, but also a case where a gasket is interposed between the plates and a force is applied from the outside, and a case where the plates are sealed by welding.
  • the projections and depressions of the plate according to the present invention can be formed as a corrugated pattern extending in a predetermined direction, and hence a complicated passage curved two-dimensionally can be formed with a relatively simple arrangement.
  • a plate heat exchanger is constructed from the above heat exchange elements as follows: A required number of the heat exchange elements are piled in such a manner that the opening portions at both ends and the element peripheral sealing portions which are to form a passage for a second fluid by sealing adjacent heat exchange elements are aligned with each other. The brazing filler material is laid on surfaces on which the opening portions of the heat exchange elements and the element peripheral sealing portions are piled. The heat exchange elements are brazed under heat in such a state that a force is being applied in a direction of piling. Consequently, the heat exchange elements are sealed at their peripheral portions, so that a plate heat exchanger having a sealed portion serving as a shell can be manufactured at a time.
  • One of the opening portions at both ends of the plate is provided with a rising portion, so that positioning of the plates upon piling can be facilitated by the fitting of the opening portions.
  • the two-dimensional positioning of the heat exchange elements can naturally be performed by simply piling the heat exchange elements on each other. Consequently, the manufacturing process can be simplified.
