Definitions
- the invention relates to a cooler arrangement, each consisting of two header boxes having coolers, for cooling various fluids, whose in at least one Row of flat tubes connecting the header boxes across the fan axis of the radial fan arranged inside the cooler arrangement run with a front wall and a rear wall as well as with inlet and outlet and with inlet and outlet Drain lines for fluid flowing through at least two coolers Collection boxes are connected.
- the cooler arrangement is based on the previously unpublished patent application DE 199 50 753.8 by the applicant.
- the inflow and outflow lines are relatively flat there and therefore save space educated. They connect the two side and the bottom in Fig. 1 there arranged coolers, which are coolant coolers there. Entry and exit the inflow or outflow lines in or out of the collection box are carried out there via the End faces of the collection box. The inlet and outlet of the coolant are on the back wall. With such training, not everyone can Operating and connection conditions are met.
- the object of the invention is to design the cooler arrangement so that it is suitable for other conditions of use or connection, the compact and space-saving design should be retained and an efficient one Heat exchange in the coolers connected to the inlet and outlet pipes can take place.
- the solution according to the invention is that the one inlet or outlet at the Rear, preferably in a corner area of the rear wall, and the other zu-or Drain on the front, preferably in the diagonal corner area of the Front wall, is arranged, the length and the cross section of the inlet and outlet Drain lines for each connected cooler is approximately the same and the inlet and outlet Drain lines are modularly pluggable.
- the arrangement of the inlets and outlets according to the invention ensures a even distribution of the amount of coolant to the cooler without To have to arrange regulatory elements in the lines.
- the length of the Zu and Drain lines to and from the coolers are at least approximately the same size. Consequently the flow resistances are about the same, which means that all connected cooler in about the same amount of coolant and in all connected coolers equal temperature differences between the Cooling air and the coolant are present, creating an efficient heat exchange is reached.
- the cooler arrangement according to the invention is for different types of connection Suitable, the one inlet or outlet on the front wall and the other inlet or Require drain on the rear wall. Because of the modular The inlet and outlet lines can be plugged together differently Circuit variants implemented economically using many identical parts become.
- the inflow or outflow lines have a flat, preferably rectangular, Cross section on, whereby the cooler arrangement remains compact. They consist of Elbows, sleeves, T - pieces and cross pieces made of plastic injection molding and from straight and / or curved line sections, preferably from Aluminum, for example manufactured as an extruded profile.
- the inlet or outlet on the rear wall has two long inlet or outlet lines for the entry or exit of two coolers and a short inlet or outlet line for the third cooler and the inlet or outlet on the front wall has a long inlet or Drain line and two short inlet or outlet lines, the length of the inlet -or drain lines for all three coolers is approximately the same.
- claim 5 stipulates for two coolers that the inlet or outlet Drain on the rear wall has a long and a short inlet or outlet pipe and the inlet or outlet on the front wall as well, the length of the inlet or outlet Drain lines of two coolers is approximately the same.
- the cooler arrangement is box-shaped and is intended for motor vehicles. 1 and 2, the upper cooler 1, a charge air cooler and the two side coolers 2 and 4 and the lower cooler 3 of the cooler arrangement can be seen, as well as a radial fan 7 enclosed by the cooler arrangement with a fan axis V.
- the cooler arrangement has a front wall F and a rear wall R.
- the flat tubes 8 of all coolers 1, 2, 3, 4 run transversely to the fan axis V. They were only partially drawn in in FIG. 1 in the side cooler 2 .
- the coolers 2, 3 and 4 are coolant coolers which are connected by means of the inlet and outlet lines L.
- arrows 6 have been drawn in, which indicate the direction of flow through the lines L and the coolers 2, 3 in the flat tubes 8 .
- the flat tubes 8 thus run in the direction of the arrows 6 shown in the figures in the coolers 2, 3 and 4 and thus transversely to the Vertilatorachse V shown in FIG. 1.
- the inlet Z of the cooling liquid is arranged in the corner region E on the rear wall R.
- the drain A is located in the diagonal corner area E on the front wall F.
- the coolers 1, 2, 3 and 4 each have two collecting tanks 5, whereby two collecting boxes 5 of adjacent coolers 1 and 2, 2 and 3 as well as 4 and 1 form an edge of the cooler arrangement where they lie closely together in order to close off the cooler arrangement and thereby force the cooling air sucked in by the radial fan 10 (FIG. 7) between the flat tubes 8 the cooler to flow through.
- 1 to 6 show the collecting boxes 5 lying one against the other.
- the inlet or outlet lines L have an approximately rectangular cross section. Their length is about the same - related to each individual cooler. In FIG. 1, the vertical inlet or outlet line L leads to the cooler 3 and the horizontal one to the cooler 5. The lengths of the inlet or outlet lines L of these two coolers 3 and 5 are approximately the same. From Fig. 2 it can be seen that the longer curved line 12 is assigned to the cooler 2 , so that overall there are approximately the same line lengths for each cooler 2, 3, 4 .
- the inflow or outflow lines L consist of straight line sections 11, of curved line sections 12, of elbows 13 and cross pieces 14 which are connected by means of connecting sleeves 15 . They can be plugged together using seals 16 .
- the straight and curved line sections 11; 12 consist of extruded aluminum profiles.
- the manifold 13 and the cross pieces 14 are molded plastic parts. With such a design, any circuit variants, ie fluidic connections of several coolers, can be implemented inexpensively.
- the side cooler 2 and the lower cooler 3 are connected by means of the inlet and outlet lines L. These are also provided as coolant coolers.
- the other side cooler 4 can, for. B. serve the oil cooling.
- the vertical line L in FIG. 3 leads to the lower cooler 3.
- a cross piece 14 (FIG. 7) is arranged at the inlet Z so that the cooling liquid can also reach the side cooler 2 via a short line attachment.
- Fig. 4 shows that the longer, curved line 12 leads from the side cooler 2 to the outlet A.
- the lengths of the inlet or outlet lines L assigned to each cooler 2 and 3 are approximately the same.
- One inlet or outlet Z, A can be found in a corner area E of the rear wall R and the other inlet or outlet Z, A can be found in the diagonal corner area E of the front wall F.
- These features common to all variants also have the exemplary embodiment from FIGS. 5 and 6 in which the two side coolers 2 and 4 are connected to one another.
- the rear wall R has not been drawn in FIG. 5 and the front wall F has also been omitted in FIG. 6. This makes the radial fan 7, which is located inside the cooler arrangement, visible.
- FIG. 7 shows a T-piece 14 which can be produced as an injection molded part and FIG. 8 shows an inlet or outlet line L.
- the cross piece has a round inlet or outlet connection and three flat branches which are connected by means of the sleeves 16 (FIG. 8). can be plugged together with the elbows 13 or the straight 11 or curved line sections 12 as required. Seals 16 are used for this.
