Description
Technical Field
The invention relates to a heat exchanger plate comprising: a heat exchange area in the heat transfer plate, a mounting rail guiding area at an edge of the heat transfer plate, a recess in the edge, and an insert mounted in the recess.
Background
Such heat exchanger plates are used to form plate heat exchangers. For this purpose, a stack of such heat exchanger plates is arranged between two end plates. To facilitate stacking of the heat exchanger plates, one or two support rods are used. The heat exchanger plates are mounted on the one or two support rods. The support rods ensure a correct alignment of the heat exchanger plates.
However, the support rods may have different designs or shapes. Depending on e.g. the size of the heat exchanger plates, the number of heat exchanger plates to be assembled or other reasons. Therefore, a support bar must be selected that is always adapted to the guide area of the mounting rail.
Disclosure of Invention
It is an object of the invention to be able to use the same heat transfer plate independently of one or more support bars.
This object is solved by a heat exchanger plate as initially mentioned, wherein the largest width of the recess in a direction parallel to the edge is located at the edge and the mounting rail guide section is provided in the insert.
In this way, the heat exchanger plates can be easily adapted to different shapes or forms of the support rods. The only necessary step is to use a suitable insert, i.e. an insert having a support bar guiding section adapted to the support bar or bars used. Since the largest width of the recess in a direction parallel to the edge is located at the edge, the heat transfer plate itself is not guided directly on the support bars, i.e. the heat transfer plate does not have a geometry engaging the guide support bars. Thus, only the insert has a guiding function. The recess is open to the edge so that the insert can be easily inserted.
In an embodiment of the invention, the recess comprises a boundary having pairs of sections directed away from the edge, wherein each pair of sections are arranged parallel to each other or offset from each other. Thus, the insert may easily move into the recess without being obstructed by any part of the heat transfer plate.
In an embodiment of the invention, at least one pair of sections forms an insert guide. As a result, the insert is guided in the width direction of the recess, so that a precise positioning of the insert on the heat transfer plate is achieved.
In an embodiment of the invention, the insert is in the form of a snap-in member. The insert can be easily mounted on the heat transfer plates simply by snapping it onto the heat transfer plates.
In an embodiment of the invention, the parts of the snap-in member are arranged on both sides of the heat transfer plate. The insert is securely held on both sides of the heat transfer plate. This reduces the risk of separation of the heat transfer plates and the insert even when the heat exchanger plates are stacked on one or more support bars.
In an embodiment of the invention, the heat transfer plate comprises at least one recess, and the snap-in member comprises at least one protrusion extending into the recess. Preferably, more than one recess is provided. When mounting the insert to the heat transfer plate, the protrusion initially contacts a surface of the heat transfer plate and enters the recess upon further movement of the insert towards the heat transfer plate. In this case, the protrusion and the recess form a positive lock.
In an embodiment of the invention, the recess is in the form of a through opening. Thus, it may be checked whether the protrusion has correctly entered the recess and has locked the insert with the heat transfer plate.
In an embodiment of the invention, the recess is arranged in a deepened region. The movement of the protrusion in a direction away from the surface of the heat transfer plate may then be kept small.
In an embodiment of the invention, the heat transfer plate comprises at least one step in the support bar guiding area, wherein the insert abuts against the step. The step portion may be formed by deforming the heat transfer plate or simply by providing another protrusion. The step allows for a precise positioning of the insert relative to the heat transfer plate.
In an embodiment of the invention, the thermal insert is made of a plastic material. Since the insert is located outside the fluid flow path and is therefore not in contact with any fluid, the insert may be made of any suitable inexpensive material, in particular a plastic material.
Drawings
The invention will now be described in more detail with reference to the accompanying drawings, in which:
figure 1 schematically shows the mounting of a plate heat exchanger,
fig. 2 shows a portion of a heat transfer plate with an insert from one side, an
Fig. 3 shows a portion of the heat transfer plate with the insert from the other side.
Detailed Description
Fig. 1 schematically shows an arrangement for mounting a plate heat exchanger. The heat exchanger comprises a front plate 1 and a rear plate 2. A plurality of heat exchanger plates 3 are arranged between the front plate 1 and the rear plate 2. The heat exchanger plates 3 are finally arranged in a plate package 4. The gasket 5 is located between adjacent heat exchanger plates 3.
To facilitate stacking of the heat exchanger plates 3, the front plate 1 and the rear plate 2, support bars are used, namely a top support bar 6 and a bottom support bar 7.
Once all the heat exchanger plates 3 have been stacked between the front plate 1 and the rear plate 2, tie rods 8 are used together with a base profile 9 to secure the stack of plates.
The front plate 4 comprises four connections 10, two of the connections 10 belonging to a first fluid flow path and the other two of the connections 10 belonging to a second fluid flow path. The two fluid flow paths are separated by the heat exchanger plates 3.
In order to screw the heat exchanger plate 3 onto the support rods 6, 7, the heat exchanger plate 3 needs to be adapted to the geometry of the support rods 6, 7. Thus, when the geometry of the support bars 6, 7 is changed or when other support bars 6, 7 are used, the corresponding geometry of the heat exchanger plates 3 has to be changed.
In order not to be limited by the requirement to adapt the entire heat exchanger plate 3 to the respective support bars 6, 7, the heat exchanger plate 3 comprises heat transfer plates 11 (parts of which are shown in fig. 2 and 3) and inserts 12.
The insert 12 is mounted in the recess 13 of the heat transfer plate 11. The recess 13 is arranged at an edge 14 of the heat transfer plate 11. The recess 13 has a maximum width at the edge in a direction parallel to the edge 14. A support bar guide section 15 is provided in the insert 12.
Figures 2 and 3 show the insert provided for the top support bar 6. However, the same arrangement may be provided at the lower part of the heat exchanger plates 3, so that the heat exchanger plates 3 are adapted to the lower support bars 7.
Thus, only the insert 12 serves to guide the heat exchanger plates 3 over the support rods 6. The heat transfer plate 11 does not require any parts to be joined with the support bars 6, 7, so that the same geometry of the heat transfer plate 11 can be used independently of the form of the support bars 6, 7. When using the other support bar 6, 7, only the insert 12 needs to be replaced.
The recess 13 comprises a first pair of sections 16, 17 directed away from the edge 14 and a second pair of sections 18, 19 also directed away from the edge 14. Each pair of sections 16, 17 and 18, 19 is arranged parallel to each other or slightly offset from each other. Therefore, the insert 12 can be inserted into the recess 13 without being obstructed by any portion of the heat transfer plate 11.
The sections 16, 17 form insert guides, such that the insert 12 is guided at these sections 16, 17 when mounting the insert 12 to the heat transfer plate 11.
The insert 12 is in the form of a snap-on member. To this end, the insert comprises joints 20, 21, 22 (fig. 2) on one side of the heat transfer plate 11 and joints 23 to 26 (fig. 3) on the other side of the heat transfer plate 11.
The joints 20 to 22 are provided with projections 27 to 29 visible in fig. 3. The heat transfer plate 11 comprises a plurality of recesses 30 to 32, which plurality of recesses 30 to 32 is in the form of a through opening, so that it can be checked whether the protrusions 27 to 29 have entered the recesses 30 to 32.
The joints 23, 26 comprise protrusions 33, 34, which protrusions 33, 34 have entered recesses 35, 36, also in the form of through openings, in a state in which the insert 12 is mounted to the heat transfer plate 11, so that it is possible to check whether the protrusions 33, 34 have entered the recesses 35, 36.
The insert 12 is made of a plastic material. Thus, the joints 20 to 22, 23 to 26 are slightly deformable, so that when the insert 12 is pushed onto the heat transfer plate 11, the joints 20 to 22, 23, 26 are pushed away from the heat transfer plate 11. The projections 27 to 29, 33, 34 are moved along the surface of the heat transfer plate 11 until they reach the recesses 30 to 32, 35, 36 to snap into the recesses 30 to 32, 35, 36.
The heat transfer plate 11 comprises a step 37 (or any other protrusion), against which step 37 the insert 12 abuts when the insert 12 is mounted to the heat transfer plate 11. Further, the heat transfer plate 11 comprises deepened areas 38 to 40, the recesses 30 to 32 being arranged in the deepened areas 38 to 40. The deepened areas 38 to 40 are slightly deformed out of the plane of the heat transfer plate 11.
In a manner not shown, a deepened area may be provided on the other side of the heat transfer plate 11. In this case, the "deepening" points in the other direction.
