Definitions
- the invention relates to a heat exchanger based on a flat base body and a film, at least one of the two molded parts having an optionally meandering channel, which forms a closed channel in the composite of the two molded parts, through which the heat transfer medium flows.
- thermoplastic materials instead of metals for the construction of heat exchangers also offers enormous flexibility in terms of shape
- plastic heat exchangers Because of the low thermal conductivity of plastics, known plastic heat exchangers have a large heat exchange surface, for example in the form of tubes or plates, and / or a low material thickness of the exchange surfaces.
- the object of the invention is to realize a simply constructed heat exchanger which is cheaper to manufacture than is possible with conventional designs. Furthermore, due to the increasing complexity of the available installation spaces, there is also the task of converting the heat exchanger into existing plastic components, e.g. in the vehicle - air filter housing, suction modules, valve covers, cooling modules, oil pans - or e.g. to integrate in data technology in housings, circuit boards etc. or in ventilation technology. Another object is to use a heat exchanger for heat removal from decentralized local heat centers such as e.g. within electronic circuits, electromechanical drives, fuel cell drives etc.
- the invention relates to a heat exchanger, at least comprising an in particular flat base body made of thermoplastic material and one the base body applied film made of thermoplastic material and inlet connector and outlet connector for supplying and removing a heat transfer medium, the base body on its underside and / or top side and / or the film having at least one channel which, in conjunction with the base body and the film, has a channel for it forms the passage of the heat transfer medium.
- the channel runs meandering on the top and / or bottom of the base body.
- the channel has a cross-sectional area, in particular when using liquid media, from 1 to 200 mm 2 and, in particular with gaseous media, from 1 to 500 mm 2 .
- thermoplastic film has a thickness in the range of 0.05 to 1.5 mm.
- a polyamide for example polyamide 6.6 or polyamide 6, polycarbonate (PC), polyalkylene terephthalate, in particular polybutylene terephthalate (PBT), acrylonitrile-butadiene-styrene copolymer (ABS), polyethylene (PE), is preferably used as the thermoplastic plastic for the heat exchanger.
- PC polycarbonate
- PBT polybutylene terephthalate
- ABS acrylonitrile-butadiene-styrene copolymer
- PE polyethylene
- PE polyethylene
- PP Polypropylene
- PTFE polytetrafluoroethylene
- TPU thermoplastic polyurethane
- PVDF Polyvinylidene fluoride
- TPE thermoplastic elastomer
- Outlet pegs are preferably connected in one piece to the base body.
- a particularly preferred embodiment consists of a combination of the heat exchanger with a motor vehicle molded part, for example an air collector of a motor vehicle, which is produced using shell technology from thermoplastic material (PA 66). Correspondingly meandering channel segments are formed on the inside of the molded part. A streamlined film is welded on by laser welding. The connections of the heat exchanger are also provided on the outside of the molded part. This creates a heat exchanger integrated in the air collector of the intake manifold, which is adapted to the aerodynamic three-dimensional shape of the intake manifold. In this case, the special cooling capacity is created by the fresh air of the engine intake that blows past the surface of the heat exchanger at high speed. The cooling power thus obtained can be used to cool the engine control electronics (the electronics housing is equipped with the same segment).
- the invention also relates to a method for producing a heat exchanger, the base body, optionally with a channel, first being produced by the injection molding process known per se and a film optionally being vacuum-formed for attachment of the channel, and then the base body and the film to form the channel one above the other placed and connected to each other by laser welding.
- FIG. 1 shows a partial cross section
- FIG. 2 shows a diagonal section of a special embodiment of the heat exchanger shows heat exchanger according to the invention along the line AA in Figure 2, explained in more detail.
- the flat base body 1 of the heat exchanger has a meandering channel 7 or 7 '(FIG. 2) with a semicircular cross section on the top and on the bottom as well as an inlet nozzle 4 and outlet nozzle 9 for the supply and discharge of the heat transfer medium ,
- the meandering channels 7, 7 'from the top and bottom are connected at their intersections 10 via an opening in the base body 1.
- the heat transfer medium can flow on the top and on the bottom of the base plate 1.
- This base body 1 was produced by the injection molding process.
- a laser-formed film 3 or 3 'with a thickness of 0.4 mm is applied by laser welding 5 (FIG. 1), which also has a meandering channel 8 or 8' with a semicircular cross section , Both the base body 1 and the film 3, 3 'consist of polyamide 6.6.
- the trough 8 or 8 'of the film forms the counterpart to the trough 7 or 7' of the base body, so that the welded troughs form the overlying troughs 7, 8 and 7 ', 8', a closed channel 6, through which the heat transfer medium flows.
- the cross section of the channel 6 is approximately 20 mm.
- the heat exchanger is used in the motor vehicle engine compartment and is operated with a 1: 1 water-glycol mixture as a heat transfer medium.
- the size is approx. L x W x H approx. 150 x 100 x 15 mm.
