Definitions
- the invention relates to a heat exchanger, in particular a soldered Heat exchanger according to the preamble of claim 1, as well as a Pipe connecting element.
- Heat exchanger in particular radiator or heating heat exchanger for motor vehicles are the primary side of a fluid, in particular from Coolant flows through a coolant circuit of the motor vehicle, wherein the connection to the coolant circuit via connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- connection piece at Radiator is connected to the pipe connection lines for the coolant become.
- a first flange is provided on the radiator, with a second flange in the vehicle for the coolant connection is connected.
- the flange for brazed radiators, it is known the flange as an aluminum part produce, which is soldered to the radiator.
- the flange in Plastic executed and formed in two parts.
- the plastic flange is made in the form of two molded parts, which are plugged into the metal connecting pieces of the heat exchanger are preferably formed as a radiator for a motor vehicle is. Since the soldered radiator with its connecting piece made of metal, preferably Made of aluminum, would be in one piece Flange example of plastic or aluminum or a Aluminum alloy give tolerance problems concerning the socket distance - This problem is due to the division of the flange in two Flange halves, which are adjustable in their distance, solved.
- the vehicle-side counterflange connected to the radiator flange is connected for fastening the coolant connection pipes, can therefore also be in plastic, aluminum or an aluminum alloy be executed, resulting in a further cost reduction in the heating circuit leads.
- Fig. 1 shows a section of a radiator 1 with a collecting box 2, also called water tank.
- the radiator 1 is designed as a soldered all-aluminum heat exchanger and is used for the heating of air for a vehicle interior of a motor vehicle, not shown.
- the water tank 2 has two connecting pieces 3, 4, which also consist of aluminum and are soldered into corresponding passages 2a, 2b on the water tank 2. Between the two connecting pieces 3, 4 is located in the water tank 2 a partition, not shown, which causes a U-shaped flow through the not fully shown radiator 1 (deflection of the coolant "in width"). One of the two connecting pieces 3, 4 is thus the inflow and the other of the return connection.
- the two connecting pieces 3, 4 each have a not here recognizable annular flange, via which in each case designed as an open ring retaining clip 5, 6 attacks, which is known per se, for. B. in a similar form by the aforementioned DE-A 196 48 162 of the Applicant. Both connecting pieces 3, 4 have a fixed distance a (from nozzle longitudinal axis to nozzle longitudinal axis). As far as this radiator corresponds to the prior art.
- a spectacle-shaped Flange 7 (double flange) made of plastic, which consists of two equally formed flange halves 8, 9, wherein the flange half. 9 only incomplete (dashed) is shown.
- the following description the flange half 8 thus applies mutatis mutandis to the flange half 9.
- Each Flange half 8, 9 has a through hole 8a, 9a, which a the distance a corresponding distance a 'have, d. H. the through holes 8a, 9a are aligned with the connecting pieces 3, 4.
- the Flange half 8 has on the water tank 2 side facing a Connecting piece 8b, which, in a manner not shown in the connecting piece 3 of the radiator 1 plugged by sealing means, not shown sealed and axially fixed by the retaining clip 5.
- a Connecting piece 8b which, in a manner not shown in the connecting piece 3 of the radiator 1 plugged by sealing means, not shown sealed and axially fixed by the retaining clip 5.
- an annular flange 8c (only partially visible), which overlapped parts of the retaining clip 5 becomes.
- the flange 7 with its two flange halves 8, 9 with the radiator 1 mechanically and fluid, d. H. coolant retention connected.
- the flange 7 is in a dividing plane T, indicated by a dashed line is indicated and runs at the height of half the distance a, divided.
- the Flange half 8 has in its peripheral region in the vicinity of the dividing plane T a tab 8d, while the opposite flange half 9 in its corresponding peripheral region has a latching hook 9e, which engages in the tab 8d and locked with this.
- On the opposite, invisible side of both flange halves 8, 9 is a corresponding Provided latching connection, wherein the tab on the flange half 9 and the locking hook on the flange half 8, that is exactly the opposite as above, is provided.
- a metal nut 10 is inserted between the two flange halves 8, 9, which as an abutment for a screw with a not shown Counterflange is used.
- This counter flange does not take the ends of shown coolant connection pipes and connects them with the radiator-side flange 7. This is a simple and quick installation, d. H. a quick coolant connection possible.
- Both flange halves 8, 9 are - as mentioned - as so-called equal parts trained and can therefore be made with the same injection molding tool become.
- the plastic is preferably PPA, PA or another plastic used.
- Fig. 2 shows a modified embodiment of the invention with a radiator 11, consisting of a network 12 and two water boxes 13, 14.
- this radiator 11 has a longitudinal partition wall 15 in the water tank 14, wherein on both sides of the longitudinal partition wall 15 connecting pieces 16, 17 are located.
- the coolant flowing through the radiator 1 is thus deflected "in the depth", ie in or against the flow direction of the air flowing through the network 12.
- the connecting pieces 16, 17 are thus arranged “obliquely” to each other.
- a two-piece flange 18 is provided made of plastic for attachment of coolant connection pipes, not shown, which is in principle formed equal to the flange 7 of FIG.
- the flange is preferably made of PPA consists of two flange halves 19, 20, which are also held together by a unspecified here, but similarly formed locking connection.
- centering means are provided in the region of the graduation plane:
- the flange half 19 or 20 therefore has a molded-on dowel pin 19a and a fitting bore 19b - a dowel pin is also offset on the other flange half 20 (dashed) and a fitting bore (not shown) is provided.
- These centering facilitate the installation of both flange halves and allow an adaptation of the described in the embodiment of FIG. 1 distances a, a '.
- a metal nut 21 is inserted for screwing with the counter flange, not shown.
