Definitions

  • the invention relates to a box-shaped cooling system for motor vehicles, consisting of box-shaped, from a cooling network with flat tubes and fins and collecting tanks havingdefactkeitskühlern, charge air coolers and possibly other coolers or heat exchangers, a rotating inside centrifugal fan and a front - and a rear wall and at least a surge tank.
  • Coolant radiators in the motor vehicle in order to operate effectively, require in their vicinity a space in which the cooling liquid can expand and degas.
  • a separate expansion tank or a separate from the header of the cooling liquid cooler space is used, which is in communication with the cooling circuit.
  • surge tanks usually have a filler neck to fill the cooling system and they also allow air pockets present in the cooling system to escape.
  • the expansion tank has been formed integrally with the jacket of the blower and serves as a support for a radiator.
  • this is not an indication of the way the arrangement of the expansion tank in the mentioned cooling systems.
  • the object of the invention is to provide for the said cooling system a surge tank, which fully complies with the requirements of the users both in terms of the total cost of the cooling system and in terms of its function.
  • the expansion tank is arranged so that its projection surface covers the surface of the cooling network of at least one cooler to a substantial extent and the expansion tank discharges the cooling air.
  • the surge tank is located above the upper horizontal intercooler and is arranged at an optimized distance from the same, wherein the bottom of the surge tank has the function of a baffle or the like.
  • An optimized distance is understood to be such a distance that effectively supports the direction of the cooling air emerging from the cooling network in a desired direction.
  • the expansion tank receives a cheap place at the highest point of the cooling system in order to fulfill its function of degassing of the cooling liquid can. Furthermore, the formation of the bottom of the surge tank as a baffle leads to the existing flow resistance remains within reasonable limits.
  • the expansion tank if it is provided at an optimized distance from the cooling network away, the performance of the radiator only insignificantly, at least only to a reasonable extent diminishes.
  • the cooling air drawn in by the radial fan through the opening in the front panel of the cooling system is deflected radially and forced through the cooling networks of the radiator.
  • the cooling air emerging from the cooling network also reaches the covered area of the cooling network, There to fulfill their cooling function and is directed around the expansion tank around.
  • the cooling effect can advantageously also be supported by air guide elements.
  • the surge tank may be arranged obliquely, so that its bottom surface forms an acute angle with the plane of the cooling network, whereby the expansion tank itself can act as an air guide.
  • the mentioned optimized distance from the cooling network is not constant in this embodiment, but increases according to the slope.
  • the distance on one side may also be 0, i. the expansion tank is supported on the said side directly on the cooling network or it touches the cooling network.
  • the bottom surface of the expansion tank can obtain a fluidically favorable shape, which eliminates the need for separate air guide elements.
  • the performance penalty can be compensated by the use of a centrifugal fan, which has the same power consumption significantly higher air flow rates than an axial fan.
  • the attachment of the expansion tank is preferably made directly on the cooling network.
  • holders are arranged between the flat tubes of the cooling network in corrugations free of corrugated ribs, which are metallically connected to the flat tubes and allow a sufficiently stable attachment and support.
  • the solution according to the invention is very low in terms of the total cost of the cooling system, compared with cooling systems that provide the surge tank on a collecting box, because standard headers can be used for the cooler of the cooling system.
  • the solution according to the invention can also be used very easily equalization tank different size without extensive changes to the other parts of the cooling system are required.
  • the box-shaped cooling system 1 consists of an in the picture above arranged intercooler 2, the collecting tanks 10; 11, a charge air inlet 21, a charge air outlet 22 and a cooling network 8, which has not been drawn.
  • the cooling network 8 is in principle identical to the cooling network 8 of the cooling liquid cooler 3, which is apparent from Fig. 1.
  • the cooling network 8 consists of flat tubes 7 and arranged between the flat tubes 7 corrugated fins 6. The ends of the flat tubes 7 are connected to opposite header boxes 10 and 11. The cooling liquid or the charge air to be cooled flows on the way from the collecting box 10 to the collecting box 11 through the flat tubes 7 and is cooled by means of cooling air flowing through the corrugated fins 6.
  • the cooling air is drawn by a centrifugal fan 14 through an opening 20 located in the front wall 16 with an inlet nozzle 15 ( Figure 3) and conveyed through the cooling nets 8 of all the radiators of the arrangement.
  • the cooling system 1 is closed at the rear by means of the rear wall 17.
  • the expansion tank 4 contains coolant and is fluidically in a manner not shown z. B. connected to the cooling liquid cooler 3 and is part of the circuit. It is located at the highest point of the cooling system 1, so that there can escape gas bubbles from the cooling liquid.
  • a filler neck 13 is arranged on the expansion tank 4.
  • the expansion tank 4 has a distance a from the cooling network 8 of the charge air cooler 2.
  • the expansion tank 4 covers the entire surface of the cooling network 8 in this embodiment.
  • the expansion tank 4 can be designed with the same capacity with less height, whereby the overall height of the cooling system 1 is reduced.
  • the bottom 5 of the surge tank 4 has in this embodiment, no constant distance a to the cooling network 8.
  • the distance a increases from the front to the back of the cooling system 1, whereby the bottom 5 assumes the function of a baffle and the majority of the outflowing cooling air (arrows in Fig. 1) either for further use or to the outside. Where the small distance a is present, it has been found to be advantageous to close this distance a with a cover plate 9 to selectively dissipate the cooling air.
  • Such an arrangement of the surge tank 4 affects the cooling performance only insignificantly and is an excellent compromise in terms of high cooling performance with a compact design of the entire cooling system and the requirement of the arrangement of the surge tank 4, as a prerequisite for a functioning cooling system of the motor vehicle.
  • the expansion tank 4 has been attached by means of holder 12 to the intercooler 2.
  • FIGs. 4 and 5 An advantageous attachment of the surge tank has been shown in Figs. 4 and 5.
  • the two figures show only the intercooler 2 or a part thereof and the expansion tank 4.
  • the attachment shown is mainly used when a surge tank 4 can be used, which covers a smaller part of the surface of the cooling network 8 than in FIG to 3 was shown.
  • 6 shows a cross section through the intercooler 2 in the region of the holder 12.
  • the intercooler 2 has two rows of tubes. The end of the holder 12 extends over both rows of tubes to provide sufficient durability.
