Definitions
- the invention relates to a heat exchanger sheet with an appertaining packing for use in heat exchangers of the kind in which extruded sheets of thin sheet material are stacked opposite to each other and held against each other between end covers, and where along the edges the sheets have at • least one packing groove pressed into the sheet for reception of a flexible packing whereby flow channels are formed between the sheets for the media between which exchange of heat is to take place.
- the heat exchanger sheet according to the invention is characteristic in that the side walls of the packing groove below the edge of the groove are provided with a number of local recesses opening into the groove so that in the area of the recesses the clear opening of the packing groove is wider than the opening of the packing groove, and so that the packing is shaped with projecting side parts fitting into the said recesses.
- this heat exchanger sheet is based on the recognition that fixation of a packing in the packing groove of a heat exchanger sheet serves exclusively to hold the packing in position when the heat exchanger is assembled or opened for inspection.
- Fixation of the packing for this purpose along the entire length of the packing such as is the case with prior art g_.ueing or use of packings with a continuous trapeziform profile, has appeared to be unnecessary.
- the recesses may have the form of a spherical segment, or they may have the form of a cylinder surface ending in a hemispherical segment at either end. Such a design results in an easily manipulable fixation engagement.
- the trapeziform can be used for fixation purposes as according to the invention opposed recesses may be designed in such a way as to impart a trapeziform cross section to the packing groove over a short distance.
- the packing groove is provided with a suitable number of recesses and that the packing is provided with a suitable number of projecting side parts distributed along the lengths of groove and packing respec ⁇ tively.
- Fig. 1 shows a heat exchanger sheet according to the inven ⁇ tion, viewed from the packing side.
- Fig. 2 shows, on a larger scale, a section through the packing groove of the sheet along the line II-II in
- Fig. 1 shows, on a larger scale, a section along the line
- Fig. 4 shows a biased picture of the embodiment according to Fig. 3, with the packing shown separately.
- Fig. 5 shows part of the sheet stack in a heat exchanger, viewed from one side as indicated by the arrow 13 in
- Fig. 2 and Fig. 6 shows a changed embodiment of the stamped areas in the packing groove where the stamped area has the form of a spherical segment.
- Fig. 1 shows a heat exchanger sheet 1 with a packing 2 placed in a packing groove 3.
- the sheet has corner holes 4, 5, 6 and 7 which are connected in pairs to the flow channels 8 of the heat exchanger which are formed in the spaces between adjacent sheets.
- the flow channel 8 is connected to the holes 4 and 5 while the neighbouring channels on either side are connected to holes-6 and 7.
- the corner holes 4, 5, 6 and 7 form corner channels through the sheet stack when the sheets are stacked.
- One fluid to be heated or cooled may, for example, pass from corner channel 4 through flow channels 8 to corner channel 5, while the other fluid flows correspondingly through flow channels 8 from corner channel 7 to 6.
- the packing groove has recesses in the form of stampings in the side walls of the groove for fixing of the packing.
- Figs. 2 and 3 show packing grooves 3 with packings 2 for two adjacent sheets.
- Fig. 2 shows a section along the line II-II in Fig. 1 through an ordinary section of the groove.
- the packing groove ,3 and the packing 2 have the common rectangular profile shown.
- a corresponding section in Fig. 3 along the line III-III in Fig. 1 has been made at one of the localities 11 and shows that in this place packing 2 and packing groove 3 have been stamped locally to form a trapeziform cross section 11a; see also Fig. 4.
- the packing 2 has been provided locally with projecting side parts 2a. Parts 11a and 2a together constitute engagement according to the press button principle.
- Fig. 6 shows, in a section corresponding to Fig. 3, an embodiment where the recesses in the side walls of the packing groove 3 are shaped as spherical segments lib.
- the projecting side parts 2b of the packing 2 have a corre ⁇ spondingly curved shape 2b.
- the recesses lib may be cylinder surfaces extending in the longitudinal direction of the groove, which surfaces end in hemispherical segments, and the projecting parts of the packing will then have the same embodiment.
- the recesses 11a or lib are made in the side walls of the packing groove 3 below the edge 3a of the groove. It means that the groove edge 3a continues without interruption also at the recesses. So there will be an unbroken, continuous, tight top part, with the groove edge and packing in contact along the entire length of the packing groove.
- the flow channel 8 is located between the sheets, while the outer edge of the sheet 1 is located on the other side.
- This outer edge has a corrugated form 9 which, as shown in Fig. 5, is shaped in such a way that the outer edges of a number of sheets bear against each other and support the outer . side 10 of the packing groove 3. The result is that the heat exchanger can be used for high operating pressures without the outer side 10 of the packing groove 3 being forced outwards so that the packing 2 can be ejected.
- corrugated form 9 generally prevents or limits inclusion of sheet material from the sheet edge in the packing groove.
- the use of the local, limited, stamped recesses according to the invention nevertheless makes it possible to fix the packing 2 in the packing groove 3 without difficulty and at the same time maintain the corrugated form 9 of the sheet edge so that sufficient stiffness is available for making e.g.
- a sheet heat exchanger with a sheet thickness of only 0.8 mm which can work at an operating pressure of 25 kp/cm ⁇ , while the use of 1.1 mm sheet without the corrugated form only permits an operating pressure of 10 kp/cm ⁇ .
- Fig. 5 shows part of the outer side of a heat exchanger where a short section of the three sheets la, lb and lc bear against each other along the sheet edge.
- the corrugated forms 9 of sheets la and lc are offset half a wave width relative to the corrugated form 9 of the sheet lb so that the top of a wave of one sheet bears against the bottom of the wave of the adjacent sheet.
- the production of the localities 11 with recesses in the side walls of the packing groove can take place together with stamping and profiling of the sheet 1. It may, h wever r. _be preferred to stamp the sheet 1 first withqut_ localities 11 with stamped recesses in the ' 3 sides of the packing groove 3, and then to stamp the recesses in t-.cT side walls of the groove at the localities 11 in a subsequent operation. In this way, a simpler tool is obtained for the primary stamping of the sheet 1 and the secondary stamping of the localities 11 can be made with a single tool.
- packings of an unflexible material like e.g. teflon are used which cannot be pressed into a packing groove in the same way as a rubber packing. If the localities 11 are made by secondary stamping, the heat exchanger sheets can be stocked in a form which can be used for both unflexible packings, which are fixed by glueing, and non-glued rubber packings when the secondary stamping of the localities 11 has taken place.
- the packing groove 3 itself is shown with a rectangular profile.
- a packing 2 can also be fixed in packing grooves with different profiles like e.g. a hemispherical profile or a profile with parallel sides and a curved or hemispherical bottom.
- Heat exchangers of the type described here are made extensively of expensive sheet material e.g. acid-proof stainless steel and titanium. It is, therefore, important that the heat exchanger sheets should be made of as thin a sheet material as possible. The effect is twofold as the thin sheet also gives an increased heat transmission.
