Definitions
- the present invention relates to a plate heat exchanger, Consisting of one behind the other Package connected panels according to the generic terms of Claims 1 and 6.
- the old seal must be removed and then the groove should be cleaned of the adhesive.
- the nipples are said to be opposite the holes Have excess that they press easily into the holes and let it pull out again. It should ensure be that the gasket is securely fixed in place becomes.
- This solution poses problems because of the nipples and the seal as molded parts tolerance fluctuations subject. If the radial oversize of the nipple is too large, these are very difficult or not at all pressed into the holes become. If that succeeds, they will tear Nipples when removing the seal, e.g. B. in inspection or cleaning work, so that the seal by a new seal must be replaced.
- EP 0 123 379 B1 is a plate heat exchanger known in which the seal by means of one piece with her trained elastic projections engage in assigned openings in the base of the groove, on the Plate is attached.
- the openings are designed that they have an insertion and extraction area, in the projections without constraint with the edge of the openings are freely movable in and out of them.
- For this Area are the projections in a restricted area of the openings convertible by moving the projections in the openings in and out of them stronger Resistance by pressing between the protrusions and the Edges of the openings are opposed, the transferability the projections from the insertion and extraction position in the locked position and vice versa the elasticity (compliance) of the seal is possible.
- the object of the present invention is in a Plate heat exchangers of the generic type are a simple solution for the mechanical fastening of the seals to the Provide plates that are still safe Hold and easy removal of the seals allows.
- the nipples are not when they are inserted into the holes pressed on their entire circumference, but only locally the places where they protrude the edge of the holes. There their cross-section is smaller than the passage area of the holes there is still play between in the other places the circumference of the nipples and the edge of the holes. Due to the Elasticity of the nipple can be in the pressed material these vacant spaces dodge, resulting in a decrease the pressure and thus pressing the nipples in the holes relieved. Through this displacement mechanism are over-tolerances in the radial dimensions of the Nipple compensated very well, in other words, it can work with larger radial oversizes than still the state of the art is possible.
- either the holes have a polygonal cross section and the Nipple a circular cross section or vice versa the Nipple a polygonal one and the holes a circular one Have cross-section.
- the edge of the holes is the edge of the holes as one in the direction of insertion Threaded nipple.
- This design of the Holes have several advantages. This is how it is compared to State of the art the contact surface between the nipple and Hole increased. This creates more creative freedom at Optimization of the features essential to the invention in your Exchange ratio. It also immerses you the nipple in the holes eased as the ends of the nipple when inserted into the holes against a circumferential Radius run at the edge of the hole, which is when the Throughput results automatically. This radius allows it also to provide a radius at the transition from the nipple to the seal. On the one hand, this has manufacturing advantages when making the seal and on the other hand it diminishes the danger that the nipple on plate movements on this Point to be sheared off.
- a plate heat exchanger solved the problem in that the edge of the holes as a formed in the insertion direction of the nipple passage is.
- This hole design has several advantages. On the one hand, there is the contact surface between the nipples and hole increased. This can be done according to the prior art required radial oversize of the nipples while maintaining a secure hold of the seal can be reduced. This makes it easier to press the nipples into the holes and pull out. The other is immersion the nipple in the holes eased because the ends of the Nipples when inserted into the holes against a rotating one Radius run at the edge of the hole, which is when the Throughput results automatically.
- This radius allows it also to provide a radius at the transition from the nipple to the seal. On the one hand, this has manufacturing advantages when making the seal and on the other hand it diminishes the danger that the nipple on plate movements on this Point to be sheared off.
- the nipples have a cross section that is smaller than that The cross section of the holes is, but this at several Digits over the scope.
- the nipples a polygonal and the holes a circular cross section or conversely the holes have a polygonal passage cross section and the nipples have a circular cross section exhibit. Because of this development of the invention the nipples are inserted into the holes not pressed on their entire circumference, but only locally in the places where they protrude the edge of the holes. Because their cross-section is smaller than the passage area the hole is, there is still play between in the other places the circumference of the nipples and the edge of the holes.
- Fig. 1 shows a plate 1 of a plate heat exchanger with a heat exchange surface 2 from one to a peripheral Groove 3 inserted seal 4 made of synthetic rubber or framed by another elastic sealing material is. At the corners of the plate 1 there are inlet and outlet openings 5-8 provided for the heat exchange media. While in the plate 1 shown the inlet and outlet openings 5, 6 enclosed by the seal 4 surrounds the seal in the front and rear of the plate 1 arranged, not shown in Fig. 1 plates Inlet and outlet openings 7 and 8. In this way alternating between the plates bundled into a package Flow channels for a heat-emitting and a heat-absorbing Media formed.
- the plate heat exchanger corresponds the structure known from the prior art, so that no further explanation is required are.
- the seal 4 is without the use of any adhesive fixed in the groove 3. These are on the surface of the heat exchanger 2 opposite side in one piece with the groove trained holding parts 9 provided at appropriate intervals arranged from each other on the circumference of the seal 4 and protrude laterally from it.
- FIG. 2 shows an edge section of the plate 1.
- a second plate 1 ' which in the 3-5 is shown in sectional views, has been omitted for the sake of clarity.
- Fig. 2 From Fig. 2 it can be seen that the groove 3 from a level the heat exchange surface 2 sloping inner side wall 10, a groove bottom 11 and one back to the level the heat exchange surface 2 rising outer side wall 12 is formed, with a plate edge on the latter 13 connects.
- This plate edge 13 is not evenly, but alternately up and down as well as outwardly opening channels with a trapezoidal cross section 14 and 15 formed.
- the floors 16 of the channels are located here 14 at the level of the groove floor 11 and the floors 17 of the channels 15 at the level of the heat exchange surface 2.
- This "corrugation" of the plate edge 13 is formed that the channels 14 from the sheet metal plate 1 as Groove 3 closed troughs are pressed down. Thereby remain between the end walls 18 of the channels 14 and the outer side wall 12 of the groove 3 bridges 19 are.
- the connect cavities 20 formed below these bridges 19 the channels 15 that extend to the outer side wall 12 of the Run through groove 3 on the underside of plate 1.
- Each holding part 9 engages in two neighboring ones Channels 14 and an intermediate channel 15. It is across an entire width Web 21 connected to the seal 4, which is in the upper Integrates edge of the seal 4.
- the shape of this web 21 is not apparent from Fig. 2, but reveals itself from a summary of the cross-sectional representations according to the 3 and 4. It follows that the web 21 in the area of the bottom 17 of the channel 15 is thinner than in the area the bridges between the two channels 14 and outer side wall 12 of the groove 3, d. that is, the web 21 is in strengthened these areas.
- Two extensions 22 adjoin the web 21 at its end facing the seal 4 by a cross member 23 are connected to each other, referred to on the plate edge 13, a thinner to the outside, the extensions 22 also connects intermediate part 24, the underside of which forms an extension of the web 19.
- the extensions 22 are in the assigned channels 14, while the intermediate piece 24 on the bottom 17 of the channel 15 arranged therebetween.
- the cross section is of the extensions 22 chosen so that they through the channels 14 of the plate 1 and the channels 15 arranged behind it or, based on the drawing, overlying plate 1 ' completely fill the formed hexagonal cross section, in other words, they lie positively in the assigned, channels 14 and 15 facing each other Channels 14, 15 are open to the outside, i.e. to the environment, the holding parts 9 can expand in this direction, whereby thermal and mechanical stresses are reduced, and so that deformations of the plate edge 13 are avoided.
- FIG. 5 in conjunction with FIG. 3 shows that the bottom 16 of the channel 14 of the plate 1 ', which over the intermediate part 24 lies in the rear area around the strength of the Intermediate part 24 is raised, i. that is, it hugs to a certain extent from above to the intermediate part 24. From Fig. 3 it can also be seen that the cross member 23 in the assembled Condition of the cavity 20 formed under the bridge 19 in essentially fills out.
- the described positive design of the holding parts 9 stabilized with the covering plates 1, 1 ' the alignment of the plates 1, 1 'in the plate pack and prevented or reduced in cooperation with usual the plate formed metallic guide elements Movements of the plates 1, 1 'in the plate plane during operation due to the internal pressure of the heat exchange media.
- This training diminishes to one that acts on the nipple 25 from the edge of the hole 26 Shear forces and on the other hand facilitates the manufacture, because radii are better realized in a mold to let.
- the tip of the nipple 25 is frustoconical.
- the nipple 25 deviates from the circular cross section of the Hole 26 has a trigonal cross section, the edges 29 are rounded.
- This training is best shown in FIG. 6 out.
- a nipple cross section enveloping circle 28 is drawn.
- the diameter D1 of this Circle 28 is larger than the inside diameter D2 of the Hole 26.
- the cross-sectional area of the Nipples 25 smaller than the passage cross section of the hole 26th
- the material of the nipple 25 is thus radial and axially free flow, the indentation and Pulling out the nipple 25 into or out of the hole 26 facilitated. At the same time it is necessary for the press fit of the nipple 25 in the hole 26 taken care of by the the passage 27 created larger inner wall surface of the hole 26 is still improved.
