Definitions

the invention relates to a water / air cooler for internal combustion engines, in particular for commercial vehicles with the features of the preamble in claim 1.
the water / air cooler designed in this way is known from EP 504 034.
all connections of the side parts to the plastic water tanks are made by means of thread-cutting screws. The screwing operations are time consuming and each screw represents an individual part that must be provided. Therefore there are solutions, such as those from EP 346 602 and EP 504 635, which do not require screw connections.
positive connections are provided, which consist of pegs molded onto the plastic water tank, which snap into openings in the side parts.
the object of the invention is a simple connection, the one under narrow spatial conditions simplified assembly of the side parts with the Permits plastic water tanks and the linear expansion of the cooling network allowed.
the solution according to the invention allows the cooling network to expand in the longitudinal direction of the flat tubes.
the elasticity achieved in this area by the fold ensures additional safety.
elongated holes in the side panels are no longer necessary. However, they can be provided, to some extent, in addition. Threading screws are inserted through the holes, which are used to connect the side parts to the plastic water tanks on the opposite tank.
the screws used for this purpose have a collar formed on the screw head, the diameter of which is slightly smaller than the small diameter of the elongated hole or the hole diameter and the thickness of which corresponds to the thickness of the side part.
the assembly process was simplified in that the side parts can be brought to the cooler both in the longitudinal direction of the plastic boxes and perpendicularly thereto, that is to say from above. This is particularly important in tight spaces.
the pins are first inserted into the openings in the web part, with the locking elements on the tabs of the side parts engaging behind stops on the plastic box. The locking element ensures the temporary fastening of the side parts in their desired position. Then the screw connection can be made on the opposite box.
the arrangement of the pins on the transverse wall of the water box, which point in the direction of the flat tubes, has the additional advantage that the formability of the water box from the injection mold has been simplified and that the tool costs are not significantly increased despite the pins.
Both side parts 6 and 7 serve to support the radiator in the vehicle, for which purpose corresponding brackets 13 are provided. For this reason, their sufficient stability and also a secure connection with the plastic water tanks 1 and 2 is essential.
the upper connection 14 encircled in FIG. 1 has been shown in more detail in FIGS. 2 to 7 in several examples. It is understood that it makes no difference whether the connection 14 is provided at the top or at the bottom. 2 and 3, the pins 15 have been formed directly on the transverse wall 16 of the plastic box 1. They extend in the direction of the flat tubes, i.e. vertically upwards in the picture.
the web part 17 has a bend 18 and three openings 19.
the bend here has an angle 21 of 90 ° because the transverse wall 16 is arranged parallel to the tube sheets 24.
the size of the angle 21 is thus determined by the geometry of the water tank 1 and can easily deviate from the exemplary embodiments shown.
the openings 19 have a collar 20 which is directed upwards in FIGS. 2 and 3. It goes without saying that rounded edges are provided both on the pins 15 and on the openings 19 in order to facilitate the insertion of the pins 15 into these openings 19.
Fig. 3 shows that the pin 15 and the corresponding openings 19 are arranged to each other so that they enclose an equilateral triangle.
the shape of the individual openings 19, which is the same for all openings 19, but two openings 19 are arranged with their longitudinal axis in the direction of the longitudinal axis of the water tank 1 and the third opening with its longitudinal axis transverse to it.
the fixation is achieved in the longitudinal and transverse directions.
the locking elements 22 are semicircular in cross-section, so that when the side parts 6 and 7 are slid on, the tabs 10 bend somewhat using the elasticity and the side parts 6 and 7 can be brought into their desired position, where the locking elements 22 are formed on the water tank 1 behind Stop attacks 23.
the folded web part 17 is located only at one end of the side parts 6 and 7, not at the opposite other end of the side parts 6 and 7.
the side parts 6 and 7 can also be mounted from above by the lower end of the side parts 6 and 7 provided with the elongated holes 11 first grips the upper water tank 1 and then vertically can be moved to the target position below.
pins 15 are individual parts that could be made of metal. These pins 15 also have a cylindrical head 24, which is followed by a thread-cutting screw 25. In the transverse wall 16 of the plastic water tank 1 there are smooth-walled bores or blind holes 27 into which the pins 15 can be screwed with their screws 25. (Fig. 4a) In the exemplary embodiment according to Fig. 4, a smooth-walled pin 28 is formed on the pin 15 , which is simply inserted into the smooth-walled bore 27. Since only forces transverse to the longitudinal axis of the pins 15 have to be absorbed here, such an embodiment is also possible and even more cost-effective. 6 and 7 differ from FIGS.
