Definitions

  • the invention relates to a heat exchanger with tubes through which a coolant flows and held in a tube sheet, and with a collection space for the coolant adjacent to the tube sheet, in particular a downflow cooler for motor vehicle engines, with a collection container which passes through a partition into the collection space and one next to it running compensation space is divided and provided with a filler neck running transversely to the partition for the coolant.
  • the invention has for its object to find a design for the collecting container in downflow coolers of the type mentioned, which makes the additional arrangement of an expansion tank unnecessary, but still simplifies the filling or refilling of coolant.
  • the partition is provided at the point opposite the filler neck with an opening and on its side facing the compensation chamber with guide devices for inserting an insert which provides the space between the filler neck and the opening bridging tubular connecting piece.
  • claims 4 to 7 allow a very simple implementation, in which the insert can be inserted through the initially open end face of the compensation space and locked in its guides.
  • claims 8 to 12 have the advantage that with the insert to be inserted anyway from one side, a further pipe socket can be positioned, which receives the cooling water punch indicator and is also surrounded by an annular space that influences the Prevents swimmers from currents.
  • a finned tube block (1) which in a known manner consists of parallel tubes (2) which are interconnected by transverse ribs (3), each with an upper Collection container (4) and a lower collection container (5) is connected. These collecting tanks serve to distribute the liquid coolant flowing through the pipes (2) evenly over all pipes and to pass them in the circuit through an internal combustion engine (not shown) for a motor vehicle to be cooled.
  • the finned tube block (1) is attached to the respective collecting containers (4 and 5) with the aid of tube plates (6 and 7).
  • the tube sheets (6) also serve to fasten the individual tubes (2) of the finned tube block (1) in a known manner.
  • the entire radiator shown in FIGS. 1 and 2 can then be connected with the aid of fastening tabs (13) on the one hand to a radiator frame and on the other hand with fastening devices in the engine compartment. It is placed on a corresponding crossbeam in the engine compartment with pins (14) which protrude from the lower collecting container (5).
  • the upper collecting container (4) is designed in a special and inventive manner. It is provided with a partition (15) which extends transversely and longitudinally through the entire interior of the collecting container (4).
  • This partition (15) separates the already mentioned collecting space (12) for the coolant flowing through the nozzle (11) from an equalizing space (16) which is no longer, but somewhat wider than the underlying collecting space (12) and one for strength reasons circular wall (17) is included, the diameter of which remains essentially the same over the entire length of the collecting container (4), but has a lower height towards the inlet connection (11).
  • This insert (24) is pushed from the side of the flange (18), where the compensation space (16) has the greater clear width compared to the other side, in the direction of arrow (47) into the interior of the compensation space (16), as long as the cover (25) has not yet been placed on the open end face in the region of the flange (18).
  • this wall part (17a) there is an opening (30), which is surrounded by a filler neck (31), on which an end cover is provided in a known manner a pressure relief valve can be placed.
  • the connecting piece (29) connects to the opening (30) and therefore establishes a direct connection between the filler neck (31) and the collecting space (12) of the collecting container (4).
  • Side at least one tube (2 ') is arranged, which is directly connected to the compensation chamber (16). The degassed coolant is sucked out of the equalization chamber (16) in a secondary flow through this pipe (2 ') via the outlet connection (10).
  • the connecting piece (29) with its guide ribs (28) is designed as a one-piece insert (24) with a further pipe piece (38) is, which is concentric with the opening (23) and serves to surround a cooling water level indicator, which can be led into the interior of the collecting container (4) through a corresponding connecting flange (39), which is located next to the filler neck (31).
  • the cooling water level indicator in the exemplary embodiment consists of a hollow guide pin (40) welded to the connecting flange (39) for a float (41), the position of which can be scanned contactlessly by means of a sensor pushed into the interior of the hollow guide pin (40).
  • the float (41) is slidably guided on the pin (40).
  • the pipe socket (38) is at its lower end and below the bottom (45) with guide ribs projecting to the side (47) which, similarly to the lower end of the connecting piece (29), form a type of flange and which can be inserted into guide grooves (48) which are located in the region of section (20) on the side of the compensation space (16) facing the Partition (15) is located.
  • guide grooves (48) consist only of two grooves (48) arranged parallel to one another and open towards one another.
  • the entire insert (24) with the cover (25) still open can therefore be moved from the open end face in the direction of the arrow (47) into the compensation space (16).
  • the guide pin (40), which can be pushed in through the flange (39), is not yet in its installed position. Only the float (41) is inserted into the interior of the pipe socket (38). If the insert (24) is therefore introduced in the direction of the arrow (47), then there is no difficulty in pushing it into the desired end position shown in FIG. 3, because the rounded upper edges of the connecting piece (29) and its outer wall (32 ) when inserted on the inside of the wall (17) and thus the ribs (28) also easily enter the guide grooves (26).
  • the ribs (47) are thus guided in the associated grooves (48) in the region of the shoulder (20), so that the end position is reached in the direction of the arrow (47) by pressing the insert (24) the hollow pin (46) engages in the opening (23) and ensures the exact position of the insert (24). If this position is reached, in which the upper edges of the connecting piece (29) and its outer wall (32) form a small gap to the wall (17a) receiving the filler neck (31), then the guide pin (40) can be inserted from above and on the flange (39) are welded. The cover (25) is then placed on and welded tightly to the flange (18), for example.
  • the entire collecting container (4) is thus produced in a simple manner. It allows easy filling of the coolant into the collecting space (12) and it opens up the possibility of determining the cooling water level in a simple and precise manner.
