- a plurality of threaded tightening bolts extend between the first end plate and the second end plate and are arranged to hold with the aid of nuts or the like these plates at a desired distance from each other in order to hold the package of heat exchanger plates together.
- Plate heat exchangers are normally provided with a frame plate, a pressure plate, also called end plates, and a package of heat exchanger plates disposed adjacent to one another and placed between the frame plate and the pressure plate. Gaskets are disposed between the heat exchanger plates. The gaskets are accommodated in gasket grooves on the heat exchanger plate, which are formed during the form-pressing of the heat exchanger plates. Plate heat exchangers further comprise inlet and outlet ports, which extend through the plate package, for handling two or more media in the plate heat exchanger.
- a plurality of threaded tightening bolts extend between the frame plate and the pressure plate and are arranged to hold with the aid of nuts or the like these plates at a desired distance from each other in order to hold the package of heat exchanger plates together and to ensure that the plate heat exchanger does not leak.

- the first and second plate intermediate spaces are disposed alternately in the plate package.
- the design of heat exchanger plate for plate heat exchangers aims to use as much as possible of heat transfer or heat exchange area for the heat exchange between two or more media, but it also needs take in account how the gaskets can be applied on the heat exchanger plate to be securely fastened and to fulfil its seal functionality.
- the location of the threaded tightening bolts are preferably selected to achieve a plate heat exchanger not exposed too much stresses.
- SE-C-171 499 shows a plate heat exchanger with a frame plate, a pressure plate, a package of heat exchanger plates, two tie bars as well as a special supporting device.
- the frame plate and the supporting device are both provided with feet. Through influence from among other things the yokes a pressure is created on the pressure plate and the package of plates is kept together.
- the guiding element is also arranged to be connected to a supporting device situated at a substantial distance from the pressure plate.
- the object of the present invention is to create a construction which is gives an optimal load distribution over the plate heat exchanger still being cheaper and less complicated to manufacture than the one described above.
- the advantages are attained by using at least one guiding element for guiding the first end plate and the heat exchanger plates relatively the second end plate, and where the guiding element is releasably arranged on at least one of the threaded tightening bolts.
- the guiding element extends through an aperture and the at least one guiding element is provided with a through-hole to receive the at least one of the threaded tightening bolts and an external geometry corresponding to a cut-out of the heat exchanger plates and the first end plate.
- the plate heat exchanger is provided with two guiding elements, a first guiding element arranged in an upper portion of the plate heat exchanger and a second guiding element arranged in a lower portion of the plate heat exchanger.
- the first and second guiding element can have an identical cross section profile.
- the second guiding element further is provided with a guiding rail for movably receiving the second guiding element.
- the guiding rail for movably receiving the second guiding element is fully or partially supported by the ground.
- the at least one guiding element includes two separate parts, and the at least one guiding element and the guiding rail is made of an extrudable material.
- a supporting device is releasably arranged at a considerable distance from the first end plate at the end of the upper and lower tightening bolts, and extending between the upper and lower tightening bolts.
- the at least one guiding element is movable along the tightening bolts and where one part of the guiding element can be removed as the heat exchanger plates are pressed together by the first end plate to form the operating plate heat exchanger, where after the removed one part of the guiding element can be arranged on a free portion of the tightening bolt outside the plate heat exchanger.

- Heat exchangers are used for transferring heat between two fluids separated by a solid body. Heat exchangers can be of several types, the most common are spiral heat exchangers, tubular heat exchangers and plate heat exchangers. Plate heat exchangers are used for transferring heat between a hot and a cold fluid that are flowing in alternate flow passages formed between a set of heat exchanger plates. The arrangement of heat exchanger plates defined above is enclosed between end plates that are relatively thicker than the heat exchanger plates. The inner surface of each end plate faces the heat transfer plates.
- Figs. 1 -2 disclose a schematic view of a plate heat exchanger 1 comprising a number of compression-molded heat exchanger plates 4, which heat exchanger plates 4 are provided in parallel to each other and successively in such a way that they form a plate package.
- the plate package is provided between a first end plate 2, also called pressure plate, and a second end plate 3, also called frame plate. Between the heat exchanger plates 4, first plate interspaces and second plate interspaces are formed.
- the end plates 2 and 3 are pressed against the plate package and against one another by tightening bolts or tie bars 5a-c, which extend through the end plates 2 and 3, and which tightening bolts 5a-c are kept in place by nuts 6, 20.
- the plate heat exchanger 1 comprises a first inlet port and a first outlet port for a first medium, and a second inlet port and a second outlet port for a second medium.
- the inlet and outlet ports extend through the second end plate 3 and the plate package. It is of course also possible for the inlet and outlet ports to be disposed on both sides of the plate heat exchanger 1 , i.e. on both end plates 2 and 3.
- the two medium may be led in the same or in opposite directions relative to one another.
- the heat exchanger plates 4 in the shown embodiment are disposed in such a way in the plate package as to form first plate intermediate spaces which communicate with the first inlet port and the first outlet port, and second plate intermediate spaces, which communicate with the second inlet port and the second outlet port.
- the first and second plate intermediate spaces are disposed alternately in the plate package.
- the separation of the plate intermediate spaces may be by gaskets extending in gasket grooves formed during the form- pressing of the heat exchanger plates.
- the gaskets are usually made of a rubber or polymer material.
- the heat exchanger plates 4 are provided with a corrugated pattern to improve the heat exchange between the two fluids.
- the uppermost and lowermost of the tightening bolts 5a, 5b replace the traditional carrying and guiding bar, which otherwise serve to enable the opening/closing of the plate heat exchanger by enabling the first end plate 2 and the heat exchanger plates 4 to be moved along the carrying bar and the guiding bar while the plate heat exchanger is standing.
- the guiding element 7a, 7b is made of an extrudable material to make cheaper to manufacture and to lighten the construction.
- the extrudable material can be plastic, aluminum or any other suitable construction material.
- the guiding element 7a, 7b Since the guiding element 7a, 7b is made of an extrudable material it cannot withstand the same load as a corresponding metal construction. Therefore the load of the heat exchanger plates 4 and the first end plate 2 will be transferred to the ground via a second or lower guiding element 7b and a guiding rail 12.
- the upper guiding element 7a and the lower guiding element 7b are preferably identical to reduce manufacturing costs, but different shapes are also possible.
- the lower external geometry 10 of the guiding element 7b corresponds to an internal shape 16 of the guiding rail 12 enabling the guiding element 7b to be secured to the guiding rail 12 and to be movable along the guiding rail 12.
- the plate heat exchanger 1 is arranged on frame, which fully or partially supports the guiding rail 12.
- the upper guiding element 7a extends through an aperture 8 of uppermost portion of the first end plate 2 so that the first end plate 2 can be movable relative to the upper guiding element 7a.
- the lower guiding element 7b extends the lower guiding element 7b through an aperture 17 of the lowermost portion of the first end plate 2.
- Both the lower guiding element 7b and the upper guiding element 7a only guides the first end plate 2, whereas the load of the first end plate 2 is carried by the guiding rail 12 upon which the first end plate 2 rests.
- the heat exchanger plates 4 rest on the lower guiding element 7b and is guided laterally by the upper guiding element 7a.
- Each guiding element 7a, 7b comprise two parts 13a, 13b; 14a, 14b
- the length of the inner guiding element part 13a, 13b is preferably slightly less than the length corresponding to the total thickness of all the heat exchanger plates 4 in the package of plates and the first end plate 2.
- the length of the outer guiding element part 14a, 14b is preferably slightly less than the remaining free end of the tightening bolt 5a, 5b when the inner guiding element part 13a, 13b has been arranged onto the tightening bolt 5a, 5b.
- the upper guiding element 7a can be provided with wear protection arrangement to reduce the wear from the heat exchanger plates 4.
- the wear protection arrangement can be of a plate or rubber material or any other suitable material, and is preferably clamped onto the upper guiding element 7a.
- the guiding element 7a, 7b has an upper portion formed as an external geometry 19 having a width corresponding to the opening width of the cut-out
- both the upper guiding element 7a and the lower guiding element 7b can guide the first end plate 2 laterally, whereas the load of the first end plate 2 is carried by the guiding rail 12.
- the upper guiding element 7a and the lower guiding element 7b will also guide the heat exchanger plates 4 laterally by the external geometry 19 of the guiding elements 7a, 7b and the lower guiding element 7b will carry the load of the heat exchanger plates 4.
- the load is transferred directly to the guiding rail 12 and further to the ground.
- the external geometry 10 of the lower portion of the upper guiding element 7a guides the heat exchanger plates 4 and serves a tilting protection for the heat exchanger plates 4, when the plate heat exchanger 1 is open. It is also possible that the upper guiding element 7a fully or partially carries the load of the heat exchanger plates 4 by the external geometry 10.
- Figs. 5-6 the guiding element 7a, 7b and the guiding rail 12 is shown in more details, partial enlargement B and C of Fig. 4, as they are arranged in the plate heat exchanger 1.
- One advantage of the suggested guiding profile 7a, 7b is that the same component can be used both as a carrying and guiding bar in the upper section of the plate heat exchanger 1 as well as carrying and guiding bar in the lower section of the plate heat exchanger 1.
- the plate heat exchanger 1 serves as a weight transferring element, which also enables that the lower outer guiding element 14b can be removed when the heat exchanger plates 4 and the first end plate 2 are tighten together so that a nut 6 can be arranged on the lowermost tightening bolt 5b in abutment with the first end plate 2 and to keep the plate heat exchanger 1 in the closed operational mode.
- the plate heat exchanger 1 can also be provided with a support device 15 to enable the plate heat exchanger 1 to be opened in an easy way, which support device 15 is provide at the free end of the tightening bolts 5a, 5b and kept in place by nuts 20.
- the support device 15 extends between the two tightening bolts 5a and 5b, and ensures that distance between the two tightening bolts 5a and 5b is invariable and that forces affecting the upper tightening bolt 5a are transferred to the ground. The further details of function and operation of the support device 15 will be described in connection with the description of the opening and closing process of the plate heat exchanger 1.
- the plate heat exchanger 1 is operational mode. For enabling maintenance such as cleaning, repairing, replacing heat exchanger plates etc., the plate heat exchanger 1 can be opened.
- the nuts 20 are screwed off and the supporting device 15 and the outer guiding elements 14a, 14b are taken away of the tightening bolts 5a, 5b.
- the nuts 6 arranged to the tightening bolts 5a, 5b are screwed off and the outer guiding elements 14a, 14b are again arranged onto the free parts of the tightening bolts 5a, 5b and pushed abutment against the inner guiding elements 13a, 13b.
- the package of heat exchanger plates 4 and the first end plate 2 is still kept together by the further tightening bolts 5c.
- the supporting device 15 is once again mounted onto the free parts of the upper and lower tightening bolts 5a, 5b.
- the supporting device 15 is supported to the ground via the outer guiding element 14b and the guiding rail 12.
- the nuts 20 are brought upon the tightening bolts 5a, 5b and tightened.
- the further tightening bolts 5c are demounted. As the tightening bolts 5c are released the first end plate 2 and the heat exchanger plates 4 may thereafter be moved along the guiding elements 7a, 7b.
- the supporting device 15 is a bar, a plate iron or the like with a sufficient length to be able to hold the uppermost and lowermost tightening bolts 5a, 5b at a correct distance in relation to each other and at the same time in the open mode of service for the plate heat exchanger 1 to be able to serve as a supporting device 15 for the whole plate heat exchanger 1 together with the second end plate 2. It further ensures that forces affecting the upper tightening bolt 5a are transferred to the ground via the lower tightening bolt 5a.
- the guiding element 7a, 7b and the guiding rail 12 are preferably made of an extrudable material such as a plastic or aluminum profile, but can also be made of any other suitable manufacturing method or material.
