Definitions

  • the present invention refers to a plate heat exchanger comprising a package of heat exchange plates, each having a peripheral portion and inside of this a heat exchange portion and several port portions with throughflow ports, the heat exchange plates being permanently joined to adjacent heat exchange plates of the package both along their peripheral portions and at many places in their heat exchange portions in such manner that they leave flow passages between adjacent heat exchange plates, the ports of the plates being aligned and forming first inlet and outlet channels through the package for a first heat exchange medium, which communicate with every second flow passage between the heat exchange plates, and second inlet and outlet channels through the package for a second heat exchange medium, which communicate with remaining flow passages between the heat exchange plates, and along each of the inlet and outlet channels the port portions of adjacent heat exchange plates, which form a flow passage separated from the inlet and outlet channel, respectively, being permanently joined around the inlet and outlet channel between an outer line and an inner line located closer to the inlet and outlet channel respectively.
  • Plate heat exchangers of this kind are previously known, for example by US 3 240 268 and GB A 2 005 398. By that the heat exchange plates are permanently joined to each other no separate gaskets are required between the plates and neither any outer frame to hold the plates together. Therefore, it is possible to produce plate heat exchangers of this kind relatively cheap.
  • the expression permanently joined refers mainly to soldering but also for example welding or glueing.
  • the abject of the present invention is to eliminate the above mentioned disadvantages of the previously known permanently joined plate heat exchangers and to provide a plate heat exchanger of the initially described kind which allows a considerably higher pressure load than previously known plate hear exchangers of this kind.
  • a plate heat exchanger of the initially described kind which mainly is characterized in means arranged to keep the port portions of the heat exchange plates together along the inlet and outlet channels, said means being placed along each of the inlet and outlet channels in the plate interspaces communicating with said inlet and outlet channels, respectively, and in each such plate interspace being permanently connected to both of the heat exchange plates delimiting the plate interspace in question in an area around the inlet and outlet channels, respectively, located between said outer line and the inlet or outlet channel itself.
  • the connecting means are arranged in an area round the inlet and outlet channels respectively, located between said inner line and the inlet or outlet channels itselves.

  • the heat exchange plates are made of a thin material and by means of pressing provided with projections on both of their sides, each connecting means comprising a projection being pressed out from the port portion of a heat exchange plate.
  • the port portions of two adjacent plates, which port portions surround an inlet or outlet channel, communicating with the flow passage formed by the plates, are preferably placed in the two end planes of the plates, located furthest from each other, and each of the connecting means is formed of projections from two adjacent plates, which projections are permanently joined to each other.
  • the connecting means placed in the different spaces between the plates is arranged in line with each other perpendicularly to the heat exchange plates along inlet and outlet channels, respectively.
  • Each inlet and outlet channel is open at its one end and closed at its other end, and an end plate placed at the said other end, has a non-penetrated port portion comprising connecting means, which corresponds to said connecting means of the heat exchange places, in areas around inlet and outlet channels, and stiffening projections pressed out inside of said connecting means.
  • each heat exchange plate according to the invention with connecting means also within the above said inner line in each port portion, which means is formed by pressing together with the pressing of the remaining portions of the plate, it can be avoided that the ports of the plate become oval.
  • the above mentioned margine of the area for a sealing ring at the end plate of the heat exchanger can be utilized for the forming of the just mentioned connecting means within said inner line in each port portion.
  • figure 1 shows a perspective view of a plate heat exchanger of the kind referring to the invention
