Definitions

  • the invention relates to a heat exchanger, in particular water cooler for a motor vehicle, with two arranged on opposite sides, preferably made of plastic existing collection boxes with longitudinal and end walls or with only one collection box as well with tube sheets, the multiplicity of openings of which each hold a tube which flows a medium, with an entry and an exit and with at least one Partition in a collection box, which contains part of the medium for repeated flow forces to cool the same further.
  • Coolers are known by the arrangement of a partition in a collecting box form a low temperature area within the cooler. Because part of the medium being forced to take a further route through the cooler can improve cooling be achieved.
  • Water coolers are the central element within a cooling module for motor vehicles that not only implement cooling water cooling, but at the same time for cooling or preheating other operating materials, mainly gear oil, hydraulic oil etc. are used.
  • gear oil cooling is only included in automobiles Automatic gearbox necessary, while gearbox oil cooling is used in manual gearboxes Cooling water did not occur.
  • the object of the invention is to provide a heat exchanger, in particular one Water cooler for a motor vehicle, so that the water cooler with and can consist of essentially the same individual parts without a low temperature range. According to the invention, this object is achieved by those specified in the patent claims Features resolved.
  • the partition arranged in the collecting box has at least one inflow opening which is followed by a line running through part of the collecting tank.
  • This line leads to a drain opening, preferably in the end wall of the Collecting box and to an outflow opening, preferably in a longitudinal wall of the collecting box, which leads to a heat exchanger, for example transmission oil cooler, whereupon is not to be discussed in more detail here.
  • a heat exchanger for example transmission oil cooler
  • the plug is configured so that the drain opening and the inflow opening can be closed.
  • This training is provided in the event that the low temperature range of the water cooler is required because, for example, a water-cooled one
  • a transmission oil cooler that passes through the outflow opening Receives cooling water. Since the sealing plug placed in the line is the inflow opening blocks, the medium is caused to flow through the heat exchanger again, enters the pipe through the jacket-side opening and leaves the heat exchanger through the outflow opening.
  • the plug can be screwed into the drain opening, for example, it can but also be designed such that it can be locked.
  • a preferred embodiment has lugs arranged on the circumference of the sealing plug, which in the region of the drain opening engage the provided slots and turn the plug around the Bring the lock along the longitudinal axis.
  • the water cooler 1 has a cooling network 15 which consists of a Bundle of flat tubes 16 and fins 17 arranged between the flat tubes 16 consists. It is immaterial whether this cooling network 15 or the entire water cooler 1 in soldered Execution or as a mechanically joined water cooler 1. Preferred way however, the cooling network 15 is soldered and the header box (s) 14 are made of plastic.
  • the water cooler according to FIGS. 1 and 2 also has a collecting box 14 a cooling water inlet 18 and at the opposite header 14 a cooling water outlet 19. The connection of the flat tubes 16 in the tube sheets 20 does not have to be here To be received. In the left header box 14 of Fig.
  • the internals consist of the partition 3, the has an inflow opening 2 and an adjoining line 4.
  • the line 4 leads to a drain opening 5 arranged in the end wall 21 of the collecting tank 14, which is also useful for completely normal draining of the cooling system.
  • the line is also there 4 with an outflow opening provided in a side wall 22 of the collecting tank 14 6 in connection.
  • the jacket side provided in line 4 can also be seen Opening 7 leading to the tube sheet 20 and the ends of the flat tubes 16 arranged therein points.
  • an inserted plug 8 is also shown, the details of which are explained below. From Fig. 2 it already appears that the lockable Attachment of the plug 8 in the drain opening 5 was selected.
  • To the plug 8 has two lugs 23 on the circumference, which by rotating the Sealing plug 8 are inserted into circumferential slots 24 of the drain opening 5.
  • Fig. 3 shows the plug 8/1, which is for use with a low temperature range is provided and Fig. 4 that 8/2, for use without a low temperature range is thought.
  • the shorter plug 8/2 is the one whose head diameter is larger. This measure bears help to prevent mistakes in the manufacturing process by using the wrong one Sealing plug 8 can arise.
  • the head 25 of the shorter plug 8/2 a protrusion 26 over the inner edge 27 of the drain opening 5.
  • the plug 8/1 is not such a protrusion 26 available. It is now easy to see that, for example, in the variant 6 provides or assembles another component belonging to this variant, the Part 28 protrudes exactly into the area of the above projection 26. Then that's up easily excluded that the plug 8/2 accidentally inserted becomes.
  • FIGS. 3 and 4 or 6 and 7 show that the plug 8/1 from FIGS. 3 and 6 has a peripheral Sealing groove 29 with an O-ring 30 close to its head 25 or near the drain opening 5 to prevent coolant from escaping through the drain opening 5 can.
  • an absolute tightness is not required or the necessary tightness can be achieved only by the plug 31 in the line 4.
  • FIGS. 4 and 7 show that the plug 8/2 has a sealing groove 29 with an O-ring 30 in the area of its stopper 31, further away from the head 25 of the sealing plug 8/2.
