Definitions

  • the invention relates to a plate heat exchanger with the features of the preamble of claim 1.
  • the plate heat exchanger described in the preamble is from the international Patent application WO 98/59208 known.
  • the levels of the inlet cross section and the outlet cross section are parallel to the plane of the cover plate in this known connection piece. An angle between the two cross-sectional planes is therefore not available, or its degree of angularity is zero.
  • it is difficult to connect a metal connection line to the connecting piece, without losing the compactness of the arrangement.
  • compact arrangements often have to be made because the installation space offered, for example, in the engine compartment of a motor vehicle is very limited.
  • caseless plate heat exchanger which also belongs to the type of plate heat exchangers mentioned here, has arranged on the cover plate inlet or outlet nozzle, which protrude perpendicular to the body of the plate heat exchanger.
  • cover plate inlet or outlet nozzle which protrude perpendicular to the body of the plate heat exchanger.
  • the object of the invention is to expand the application of caseless plate heat exchangers.
  • the invention is an angled spigot, which at first glance may seem very ordinary.
  • this connection piece is made from an approximately flat plate, usually from the cover plate of the plate heat exchanger, by means of deep drawing, which poses some manufacturing problems.
  • the skilled person would in such cases rather resort to elbow and attach and solder this as a single part on the cover plate, which is disadvantageous.
  • This view is followed by the applicant, as long as it is not known such a drawn from a plate elbow in connection with plate heat exchangers.
  • the plate heat exchanger has additional features, which are specified in the subclaims and can expect the additional advantageous effects.
  • the plate heat exchanger has a vent for the cooling circuit to which it is connected. This is advantageous if the installation location of the plate heat exchanger is provided at a geodetically overhead point of the cooling circuit. Such a vent on the plate heat exchanger seems to be easier and less expensive to implement (but equally effective), as for example, a vent valve, which is arranged in a wiring harness. Further features and advantages of the invention will become apparent from the following description of an embodiment.
  • the Fig. 1 shows a perspective view of the plate heat exchanger and the Fig.
  • FIG. 2 shows a plan view of the same.
  • the Fig. 3 shows the in the Fig. 2 drawn section AA and the Fig. 4 shows the section BB from the Fig. 2 ,
  • an oil cooler which is used in a motor vehicle for cooling engine oil by means of the cooling liquid circulating in the cooling circuit of the motor vehicle engine. (Not shown)
  • the inlet channel 5 (also the outlet channel 6, not shown) is connected to the flow channels 4 , so that the cooling liquid can flow from the inlet channel 5 via the flow channels 4 to the outlet channel 6 .
  • the flow channels 3 for the engine oil which are connected in the same way with the inlet channel 7 and the outlet channel 8 .
  • the connecting piece 12 was formed by deep drawing in several stages of production from the cover plate 10 , wherein the connection opening 30 was formed in the connecting piece 12 in the last stage.
  • the angle 20 between the plane of the inlet cross section 13 and the plane of the outlet cross section 14 is about 50 °.
  • the line end 15 was used in the illustrated embodiment.
  • the line end 15 surrounds the connection opening 30 from the outside, which then has a flange approach.
  • the lead end 15 has a bead which constitutes a stop to facilitate insertion and later sealing soldering.
  • the line end 15 also has a slight bend, so that the same can extend in the immediate vicinity above the cover plate 10 , whereby the plate heat exchanger is very compact and space-saving overall, in particular has a low height, as at the left edge of the Fig. 3 was displayed.
  • the bending of the line end 15 can be dispensed with if the angle 20 between the entry plane 13 and the exit plane 14 approaches a right angle.
  • the formation of a 90 ° angle seems to be somewhat more expensive in terms of production, so that the embodiment shown can be designated as preferred.
  • the line end 15 extends at a minimum distance 16 across the cover plate 10 , it is advantageous, in particular for plate heat exchangers used in motor vehicles, when the line end 15 by means of an auxiliary bearing 40th (in Fig. 3 not shown) is supported on the cover plate 10 , because thus the vibration occurring during operation can be better met.
  • the line end 15 is indeed at least partially disposed above the cover plate 10 , but leads away from the plate heat exchanger shortly after the connection piece 12 , so that there is no auxiliary bearing 40 of this type is provided.
  • the line end 15 is arranged in such embodiments, not shown, in which a connection piece 12 is located on the base plate 9 .
  • auxiliary bearing 40 has a head 41 on which the line end 15 is fixed and a foot 42 , with which it is soldered to the cover plate 10 .
  • auxiliary bearing 40 located at the foot 42 a slight depression or the like, which cooperates with a corresponding elevation (knob) on the cover plate 10 .
  • the auxiliary bearing 40 can also be formed by deep drawing from the cover plate 10 and then does not represent a single item. (not shown) Fig.
  • connection piece 12 is directly above the inlet channel 5 and on the vertical 25th
  • the connecting piece 12 is arranged offset to the vertical 25 , but of course remains in hydraulic communication with the inlet channel 5 .
  • On the cover plate 10 is a vent 50 for the coolant circuit.
  • the vent 50 has a sealing screw 51 . To the loosening of the sealing screw 51 can escape gas inclusions contained in the cooling liquid, since the vent 50 is connected via a bore or the like to the upper flow channel 4 for the cooling liquid.
  • the plate heat exchanger has been mounted or soldered onto a mounting plate 45 for mounting to a motor housing, for example by means of screws (not shown) or similar fasteners inserted through holes 46 .
