- the oil and coolant circulate along respective sides of each intermediate plate of the stack of plates.
- the heat exchanger may also comprise a fixation plate for fixation of the stack of plates into the automotive vehicle.
- the stack of plates is for example soldered to the fixation plate which is itself fastened to the vehicle, for example with screws.
- a reinforcement plate between the fixation plate and the stack of plates is also known from US2007084809-A and EP2267390-A .
- EP0623798-A2 discloses a heat exchanger according to the preamble of claim 1.
- One aspect of the invention relates to a heat exchanger comprising a stack of plates comprising a lower plate onto which the other plates are stacked, the said other plates comprising a base plate immediately adjacent to the lower plate, the heat exchanger also comprising a fixation plate, and a reinforcement plate between the fixation plate and the lower plate, wherein the heat exchanger further comprises reinforcing inserts between the base plate and the lower plate, wherein said reinforcing inserts have an arcuate shape.
- the heat exchanger may comprise one, several or any combination of the following technical features:
- FIG. 1 shows a heat exchanger 2 typically used for oil cooling.
- the heat exchanger comprises a stack of plates 4, a fixation plate 6 and a reinforcement plate 8 between the fixation plate 6 and the stack of plates 4.
- the heat exchanger comprises a coolant inlet 10 and coolant outlet 12 going through the top end plate 14 of the stack of plates.
- the coolant is for example a water and glycol based liquid commonly used for engine cooling.
- an oil inlet 16 and an oil outlet 18 can also be seen through the lower plate 20 of the stack of plates 4, through the reinforcement plate 8 and through the fixation plate 6.
- the heat exchanger 2 is thus intended to be used as an oil cooler, for example for cooling the oil of the engine of the automotive vehicle.
- the heat exchanger could also be used for heat exchange between other fluids, such as for example between water and glycol based liquid and a refrigerant fluid such as for example 1234yf.
- the stack of plates 4 of the heat exchanger is designed so that the two fluids circulate alternately between the adjacent pairs of plates. That is to say, each fluid circulates along respective sides of each intermediate plate 22 (also called “base plates”) of the stack of plates.
- the base plates 22 have holes for the circulation of the two fluids through each base plate.
- FIG figures 3 and 5 is shown the first base plate 22' of the stack of plates 4, starting from the side of the lower plate 20.
- the heat exchanger comprises reinforcing inserts 23 ( Figure 2 , Figure 4 & Figure 5 ) between the lower plate 20 and the base plate 22'.
- the reinforcing inserts 23 are frame parts, for example of rectangular cross section. Alternatively, the reinforcing inserts 23 are inserts of any adapted cross section, for example a round cross section.
- the reinforcing inserts 23 extend internally along two corners 26 of the lower plate 20. More generally, the reinforcing inserts 23 extend along only one or more corners of the lower plate.

- the reinforced corners are the one at proximity of the holes for fluid communication 16 and 18 for oil. If the inlet and outlet of water and glycol based coolant were also designed through the reinforcement plate 8 and fixation plate 6, which is also a possible alternative, then the reinforcing inserts would be at proximity of the inlet & outlet for oil, and there would be no reinforcing inserts at proximity of the inlet & outlet for water & glycol based coolant.

- the peripheral edge 36 of each plate receives the external surface of the peripheral edge 36 of the plate above in a tight manner.
- This design is also called a "tub” design wherein each tub plate receives the tub plate above in a tight manner along the peripheral edges 36.

- the inlet & outlet of coolant could also be on the side of the fixation plate 6, in which case, there would be not circulation holes in the top end plate 14.
- the reinforcement plate 8 shown more specifically on Figure 3 is a planar plate having a relatively high thickness.
- the reinforcement plate 8 has fixation holes 70 in regards of corresponding fixation holes 72 of the fixation plate 6, in order to receive for example fixation screws intended to fasten the heat exchanger into the automotive vehicle.
- the reinforcement plate has no fixation hole and the fixation plate 6 is fastened to the automotive by holes that are external to the reinforcement plate.

- the peripheral edge 80 extends along substantially the whole contour of the reinforcement plate 6. In the figures, there is only one small region 82 where the peripheral edge 80 is not present, but the peripheral edge 80 is still present around at least 50% of the contour of the reinforcement plate 8.
