Definitions

  • the present invention refers generally to plate heat exchangers allowing a heat transfer between two fluids at different temperature for various purposes.
  • the invention relates to a plate heat exchanger comprising a first end plate, a second end plate and a package of heat exchanger plates placed between the frame plate and the pressure plate.
  • 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.
  • a plate heat exchanger according to the preamble of claim 1 is known from documents GB 2 312 042 A .
  • 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.
  • Heat exchanger plates are normally made by form-pressing of sheet metal and are disposed in the plate package in such a way 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.
  • 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 construction shows the disadvantage that both the supporting device and the pressure plate with necessity are created in the form of a very strong construction. Further on the auxiliary carrying bar to support plates in connection with mounting and demounting of the heat exchanger constitutes an unnecessary complication.
  • EP-B1-1 027 571 is shown another plate heat exchanger, where tightening bolts have been integrated into the carrying bar and the guide bar, and creates a guiding element for the pressure plate and the heat exchanger plates.
  • the localization of the tightening bolts is thereby more optimal to resist the forces laid onto the plate heat exchanger during operation.
  • the guiding element is surrounded by a protecting sleeve extending from the frame plate to the pressure plate and protecting the threads of the guiding element from engagement with the heat exchanger plates.
  • 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.
  • a plate heat exchanger having the features of claim 1
  • 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 arranged to engage 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.
  • the heat exchanger plates rest on the at least one guiding element and wherein the first end plate rests on a guiding rail, upon which guiding rail the at least one guiding element is movably received.
  • 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.

  • 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 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.
