- FIG. 11 shows a third embodiment of the present invention.
- the plastic sheets are formed as in FIGS. 1-3 with one sheet containing the flow channel(s) 14 .
- a flexible tubing 24 such as a rubber or polyolefinic tube is inserted into the flow channel(s) 14 before the two sheets 4 , 6 are attached to each other.
- Such tubes are well known in the industry and may be made of silicone, polyethylene, poly propylene, C-Flex® polymer and the like. If desired the tubing may have reinforcement such as a braid of fiberglass or metal to add additional pressure resistance to it.
- FIG. 12 shows a fourth embodiment of the present invention.
- the plastic sheets are formed as in FIGS. 8-9 with each sheet 4 , 6 containing the flow channel(s) 14 .
- a flexible tubing 24 such as a rubber or polyolefinic tube is inserted into the flow channel(s) 14 before the two sheets 4 , 6 are attached to each other.
- Such tubes are well known in the industry and may be made of silicone, polyethylene, polypropylene, C-Flex® polymer and the like. If desired the tubing may have reinforcement such as a braid of fiberglass or metal to add additional pressure resistance to it.
- FIG. 13 shows a fitting 18 A in the tubing 24 contained within the flow channel 14 .
- a hose barb 30 can be used to secure the fitting to the tubing 24 .
- the sheets can be made from a plastic selected from the group consisting of polyolefins, polycarbonates, epoxies, fiberglass reinforced thermosets, carbon reinforced thermosets, carbon composites, polysulphones and polyetherimides.
- the one or more flow channels can be formed in the rigid plastic sheet(s) in a variety of manners.
- it can be vacuum formed by preparing a pattern of the flow channel configuration on a mold, heating the plastic sheet until it is soft and then applying a vacuum to the plastic sheet so as to pull it against the pattern and form the channel configuration.
- the plastic thick enough it may be formed by removing the plastic in the areas of the desired flow path such as by a router or a CNC milling machine, a laser or chemical etching.
- the plastic is melt cast or solvent cast over a pattern containing the pattern of the flow channel configuration (either as a positive or a negative pattern) and it is allowed to cool or evaporate the solvent.
- thermosets a similar process may be used and the thermoset is allowed to cure or set against the pattern to form the device.
- the holes 22 may be formed as part of the process of making the sheets such as when the sheets are cast or they may be formed afterward such as by drilling or laser etching the hole in the desired location.
- the two sheets are aligned and securely held together in a liquid tight manner. This may be accomplished by adhesives that hold the two sheets together, or by solvents that selectively dissolve a portion of the adjoining plastic of each sheet and welds the two together as the solvent is evaporated. Heat sealing and heat or sonic or ultrasonic welding can also be used. Lasers and heat platens can be used for the heat welding. Alternatively, the two sheets can be secured by clamps around their edges. This may in some instances necessitate the use of a peripheral gasket. Likewise, a series of nuts and bolts or rivets, optionally with a peripheral gasket can be used to seal the sheets together.
- the fitting can be an elastomer material that is simply compressed and held in the flow channel as shown in FIG. 3 .
- it may be retained simply by a friction fit between the inner diameter of the flow cannel and the outer diameter of the fitting.
- the use of adhesives, heat or sonic welding or solvent welding may also be used depending upon the material selected.
- the flow channel(s) 14 may be formed with a retention device such as an undercut 100 . While shown as a rectangular undercut, it could be any other shape that retains the fitting.
- a device according to the present invention is made in the following manner.
- a lay out or design of the flow channel is charted and then a mold is formed such as by laying out metal or wood half round pieces.
- the pieces can be bent or cut to the particular configuration desired.
- the pieces are attached to a flat surface such as a vacuum board for a vacuform machine.
- the pieces can be treated with a release agent such as silicone or various machine, mineral or vegetable oils or waxes (natural or synthetic) to ensure the mold does not stick to the plastic sheet.
- a PTFE coating can be applied to the pieces.
- a piece of rigid plastic of a size to fit the board is then either simply placed over the board and pieces and then heated such as by a heat lamp or heat gun or the plastic sheet is heated until it is pliable first and then applied to the board.
- the plastic is clamped in place and a vacuum is drawn to pull the pliable plastic against the mold.
- the plastic is cooled and released from the board.
- both sheets are to contain the channel(s) either a second sheet is simply made or if it is complicated a second mold which mirrors the first (ie is reciprocal to the first) is made and a second sheet is formed in a similar manner to the first.
- the same type of mold can be used with plastic that is formed from molten material which is poured over the mold or fiberglass or other composites by manufacturing the sheets over the mold(s) and using squeegees or rollers to ensure a good molded surface.
- Another method making the device is to simply rout out the channel(s) with a router device or CNC machine or laser or chemical etch as described above.
- the device will contain tubing it is inserted between the sheets before they are secured together. If no separate tubing is used, the end fittings are secured between the sheets before or during when they are secured together. In the case of no separate tubing being in the channel(s), one may want to wash or flush the channel(s) before use to remove any release agent that may be left. Alternatively, this can be done as each sheet is made.
- the fittings are attached to a supply of liquid and a means to hold the processed material such as a bag, tank, and the like.
- the liquid is run through the channel(s) and treated such as by a filter that is in line in the device.
