- 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 exchanger plates.
- Figs. 1-2 disclose a plate heat exchanger 1 for treatment of a medium.
- the plate heat exchanger 1 comprises a large number of compression-molded heat exchanger plates 2, which are provided in parallel to each other and successively in such a way that they form a plate package 3.
- the plate package 3 is provided between a first end plate 6, also called frame plate, and a second end plate 7, also called pressure plate. Between the heat exchanger plates 2, first plate interspaces and second plate interspaces are formed.
- the first plate interspaces and the second plate interspaces are provided in an alternating order in the plate package 3 in such a way that substantially each first plate interspace is surrounded by two second plate interspaces, and substantially each second plate interspace is surrounded by two first plate interspaces.

- the first end plate 6 is connected to the support column 32 by the carrying bar 31 , which in one end is fixedly attached to an upper end of the first end plate 6 and in the opposite end fixedly attached to an upper end of the support column 32.
- the second end plate 7, which is movable along the carrying bar 31 is used to press the heat exchanger plates 2 together to form the plate package 3.
- the guide bar 33 that guides the heat exchanger plates 2 in their lower end, connects a lower portion of the support column with a lower part of the first end plate 6.
- the heat exchanger plate 2 discussed above includes in a manner known per se a corrugation or pattern for increasing the heat transfer and a number of port holes 4 for forming a corresponding number of port channels 5 extending through the plate package 3 and being in connection with the flow channels 5 formed between the heat exchanger plates 2.
- On the first end plate 6 is a number of through holes 8 (best shown in
- Fig. 5 and 7 which corresponds to the inlet/ outlet port holes 4 of the heat exchanger plates 2.
- the end plate 6 is provided with four though holes 8, but it can be fewer or more through holes 8 depending on the design of the heat exchanger plates 2. It is also possible to arrange the through holes 8 on the second end plate 7 or that both end plates 6, 7 are provided with a number of through holes 8.
- connection pipes 9 In the shown embodiments the first end plate 6 is provided with through holes 8 and corresponding number of connecting pipes 9, two through holes 8 and corresponding number of connecting pipes 9 are arranged in the lower end of the end plate 6 and two through holes 8 and corresponding number of connecting pipes 9 are arranged in the upper end of the end plate 6.
- connection pipe 9 serves as connection part interconnecting the plate heat exchanger 1 or more precisely the plate package 3 with associated pipes 12 or pipe system 10.
- the connection pipe 9 is formed as a cylindrical part 21 having a through hole 22.
- a flange portion 17 which extends outwardly, substantially perpendicular to the longitudinal extension of the cylindrical part 21.
- an external thread 1 1 is formed in the end opposite to the end of the cylindrical part 21 , which is provided with a flange portion 17, an external thread 1 1 is formed.
- the external thread 1 1 may be formed along the entire length of the cylindrical part 21 , i.e. almost to the end of the cylindrical part 21 , which is provided with an annular flange portion 17, or the external thread 1 1 might only be formed along a portion of the cylindrical part 21.
- the associated pipe 12 or pipe system 10 is formed with a corresponding internal thread 13, which interacts with the external thread 1 1 to create a secure connection between the plate heat exchanger 1 and pipe 12 and/or pipe system 10.
- the connection pipe 9 is inserted in the through hole 8 of the end plate
- connection pipe 9 is now extending from the outside of the end plate, where the outside surface is the surface 14b of the end plate 6 which is turned or directed away from the plate package 3.
- an adhesive means 16 (see Fig. 6) is provided between the flange 17 of the connection pipe 9 and the inside surface 14a of the end plate 6.
- the adhesive means 16 locks the connecting pipe 9 in relation to the end plate 6, both rotationally and axially.
- the adhesive means 16 can be a double-stick tape, a glue or similar.
- the adhesive 16 is arranged on the entire surface of the annular flange 17, but it can also be arranged on selective spots of the flange surface.
- a bushing or sleeve 15 is arranged or threaded on the external threaded portion 1 1 of the connection pipe 9 so that the bushing 15 abuts the outside surface 14b of the end plate 6.
- the bushing 15 locks the connection pipe 9 in relation to the end plate 6, at least axially.
- the flange 17 can be provided with a lip 18 on the outer periphery of the flange 17.
- the Iip18 extends axially or is directed towards the end plate 6.
- the end plate 6 is provided with a corresponding recess 19, which interacts with the lip 18 of the flange 17 so that when the flange 17 abuts the inside surface 14a of the end plate 6 the lip 18 enters the recess 19, and the connection pipe 9 cannot be rotated in relation to the end plate 6.
- the lip 18 can be shaped as a small portion of the flange 17, which is bent up from the flange surface to form a small portion extending from the surface of the flange (see Fig. 10), directed towards the end plate 6, but is can also be shaped as a small pin, peg or similar that is mounted onto the periphery of the flange 17 and extending towards the end plate 6.
- an adhesive means can be used for achieving the same.
- the connection pipe 9 is formed with an external thread 1 1 along the entire length of the connection pipe. This is shown in Fig. 8.
- the transition piece 24 can be configured so that is arranged on a portion of the external thread 1 1 of the connection pipe 9 (not shown), but it can also be shaped so that one end of the transition piece 24 can be arranged abutting the outside surface 14b of the end plate 6, thus locking the connection pipe 9 to the end plate 6.
- the transition piece 24 can accordingly be formed as piece pipe or cylinder as shown in Fig. 7 having an internal thread 13 at least along a portion of its length or having an internal thread 13 along its entire length.
- the external thread 25 is formed at least along a portion of the length of the transition piece 24. It can also be shaped as a bushing 15, see Fig.
- connection pipe 9 having a hexagonal, octagonal or suitable edge head 23 in one end of the bushing 15 and having an external thread 20 along the external surface of the bushing 15.
- the bushing 15 of Fig. 9 provides a locking means for easy locking of the connection pipe 9 to the end plate 6 and a transition piece 15 or 24 for adapting the plate heat exchanger 1 to pipes 12 or pipe systems 10 of various size.
- connection pipe 9 is arranged on the first end plate 6, but it is obvious that the connection pipe 9 can also be arranged on the second end plate 7 or on both end plates 6, 7 simultaneously, all pending on the function and purpose of the plate heat exchanger 1.
- connection pipe has been used for the part that extends through the end plate and which seals off against heat exchanger plates.
- lining has been used for corresponding parts, but where the focus is more the protecting function in relation to the end plate, and where the part substantially not extends from the end plate.
- bushing has been used to the part that locks the connection pipe to the end plate.
- the term bushing includes also sleeves, quill, casing and penetration piece.
- lip which describes the small extending part of the flange periphery of the connection pipes, include pin, peg, tap, stud, tab lug, lap and head.
