The invention relates to a plate heat exchanger (1) including a first and second end plate (2, 3), and a core of heat exchanger plates (4) arranged between the first and second end plate (2, 3), whereby a plurality of threaded tightening bolts (5a, 5b, 5c) extend between the first and second end plate (2, 3) and are arranged, with the aid of nuts (6) or the like, to hold these plates at a desired distance from each other in order to hold the core of heat exchanger plates together, wherein at least one guiding element (7, 7a, 7b) for guiding the first end plate (2) and the heat exchanger plates (4) relatively the second end plate (3) is releasably arranged on at least one of the threaded tightening bolts (5a, 5b), which guiding element (7a) extends through an aperture (8) in the first end plate (2), where the at least one guiding element (7a, 7b) is provided with a through-hole (9) to receive the at least one of the threaded tightening bolts (5a, 5b) and an external geometry (10) corresponding to a cut-out (11) of the heat exchanger plates (4) and the first end plate (2).
A plate heat exchanger comprising first and second end plates, and a core of heat exchanger plates arranged between the first and second end plates, whereby a plurality of threaded tightening bolts extend between the first and second end plates and are arranged, together with nuts, to hold the end plates at a desired distance from each other in order to hold the core of heat exchanger plates together, wherein at least one guiding element for guiding the first end plate and the heat exchanger plates relatively relative to the second end plate is releasably arranged on at least one of the threaded tightening bolts, which guiding element extends through an aperture in the first end plate, and wherein the at least one guiding element is provided with a through-hole to receive the at least one of the threaded tightening bolts and the at least one guiding element has an external geometry corresponding to a cut-out of the heat exchanger plates and the first end plate.
A plate heat exchanger comprising first and second end plates, and a core of heat exchanger plates arranged between the first and second end plates, whereby a plurality of threaded tightening bolts extend between the first and second end plates and are arranged, together with nuts, to hold the end plates at a desired distance from each other in order to hold the core of heat exchanger plates together, wherein at least one guiding element for guiding the first end plate and the heat exchanger plates relative to the second end plate is releasably arranged on at least one of the threaded tightening bolts, which guiding element extends through an aperture in the first end plate, and wherein the heat exchanger plates rest on the at least one guiding element and where the first end plate rests on a guiding rail, upon which guiding rail the at least one guiding element is movably received.
