Abstract A plate heat exchanger comprises a laterally arranged cylindrical container having an inlet and outlet for one of both media and those for the other medium and opening at one end, a plurality of heat exchange units each including a pair of opposite frames and a pack of plate elements therebetween and being inserted in sequence into the container, and a press lid attached to said one opening end of container under condition of thrusting said plurality of heat exchange units. The plate elements are clamped face to face through surrounding sealing surrounding sealing strips respectively to form between the plates interspaces through which the media flow. Every second interspace among the interspaces is closed with respect to the space within the container and communicates with said inlet and outlet for said one medium. The remaining interspaces open suitably with respect to the space within said container through partial cutouts at said sealing strips to thereby communicate with said inlet and outlet for said the other medium. Said one medium may be fluid medium and the other air medium and vice versa, which is determined by the ratio of flow rate of both media for heat exchange.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
96 words
A plate heat exchanger comprising; a cylindrical container having an inlet and an outlet for feeding and discharging one of both media respectively and an inlet and an outlet for the other, and being arranged axially horizontally to open at one end; a plurality of heat exchange units each including a pair of opposite frames and a pack of plate elements clamped face to face therebetween and being inserted in sequence into said container; and a press lid mounted to the open end of said container under condition of thrusting said plurality of heat exchange units.
Claim 2
Dependent Claim
96 words
A plate heat exchanger comprising; a cylindrical container having an inlet and an outlet for feeding and discharging one of both media respectively and an inlet and an outlet for the other, and being arranged axially horizontally to open at one end; a plurality of heat exchange units each including a pair of opposite frames and a pack of plate elements clamped face to face therebetween and being inserted in sequence into said container; and a press lid mounted to the open end of said container under condition of thrusting said plurality of heat exchange units.
Claim 3
Dependent Claim
98 words
A plate heat exchanger according to claim 1, characterized in that said plate elements are clamped face to face through surrounding sealing strips respectively to form between said plate elements interspaces through which the media flow, every second interspace among said interspaces being closed with respect to a space within said container and communicating with said inlet and outlet for the one medium, the remaining interspaces opening properly with respect to the space within said container by way of partial cutouts at said surrounding sealing strips to thereby communicate with said inlet and outlet for the other medium.
Claim 4
Dependent Claim
23 words
A plate heat exchanger according to claim 2, characterized in that the one medium is fluid medium and the other medium is air.
Claim 5
Dependent Claim
23 words
A plate heat exchanger according to claim 2, characterized in that the one medium is air medium and the other medium is fluid.
