Abstract

Systems are provided for a heat exchanger assembly. In one example the system may include a top plate, a fluid inlet and a fluid outlet, a bottom plate coupled to the top plate, a perforated plate positioned between the top plate and the bottom plate having an underside facing the bottom plate and including perforations shaped to generate an impingement jet onto the bottom plate, and at least one of the following: the top plate comprising a portion being inclined with respect to a longitudinal axis of the heat exchanger assembly; the perforated plate being inclined with respect to the longitudinal axis or a lateral axis of the heat exchanger assembly; and the heat exchanger assembly further comprising a flow control plate.

First claim

The invention claimed is:

1. A heat exchanger assembly, comprising:
a top plate;
a fluid inlet and a fluid outlet;
a bottom plate coupled to the top plate; and
a perforated plate positioned between the top plate and the bottom plate and including perforations shaped to generate an impingement jet onto the bottom plate or the top plate, the perforated plate including a flange and a lip that forms a rim along a perimeter of the perforated plate, wherein the lip divides the perforated plate into the flange and a perforated wall including the perforations,
wherein the perforated plate is inclined with respect to a longitudinal axis or a lateral axis of the heat exchanger assembly.

2. The heat exchanger assembly of claim 1 , wherein the lip is configured to slot into a groove of the heat exchanger assembly.

3. The heat exchanger assembly of claim 1 , wherein the perforated plate is substantially flat.

4. The heat exchanger assembly of claim 1 , wherein the perforated plate is inclined with respect to the longitudinal axis of the heat exchanger assembly, and wherein the top plate and the bottom plate are substantially parallel to the longitudinal axis of the heat exchanger assembly.

5. The heat exchanger assembly of claim 1 , wherein the top plate, the bottom plate, and the perforated plate are rectangular.

6. The heat exchanger assembly of claim 1 , including a second perforated plate, wherein the perforated plate and the second perforated plate are mirror oriented to generate impingement jets on the top plate and the bottom plate of the heat exchanger assembly, and wherein the top plate and the bottom plate are substantially parallel to the longitudinal axis of the heat exchanger assembly.

7. The heat exchanger assembly of claim 6 , wherein the impingement jets on the top plate and the bottom plate of the heat exchanger assembly include a first impingement jet onto the top plate generated by the perforations of the perforated plate and a second impingement jet generated by perforations of the second perforated plate, and wherein the second perforated plate has perforations shaped to generate the second impingement jet onto the bottom plate.

8. The heat exchanger assembly of claim 7 , wherein the second perforated plate is inclined such that the second perforated plate is closer to the bottom plate at a first side of the heat exchanger assembly than at a second side of the heat exchanger assembly, and wherein the perforated plate is inclined such that the perforated plate is closer to the top plate at the first side of the heat exchanger assembly than at the second side of the heat exchanger assembly.

9. The heat exchanger assembly of claim 8 , further comprising an electronic module adjacent a bottom of the bottom plate and one or more plates positioned between the perforated plate and the second perforated plate.

10. The heat exchanger assembly of claim 9 , wherein a height of the heat exchanger assembly is less than a lateral width of the heat exchanger assembly, the lateral width less than a longitudinal length of the heat exchanger assembly, and wherein the perforated plate and the second perforated plate are vertically stacked such that the second perforated plate is positioned intermediate the bottom plate and the one or more plates, and the perforated plate is positioned intermediate the one or more plates and the top plate.

11. A heat exchanger assembly, comprising:
a top plate;
a fluid inlet and a fluid outlet;
a bottom plate coupled to the top plate;
a first perforated plate positioned between the top plate and the bottom plate and including perforations shaped to generate an impingement jet onto the bottom plate or the top plate, the first perforated plate including a lip that forms a rim along a complete perimeter of the perforated plate;
a second perforated plate, wherein the first perforated plate and the second perforated plate are inclined with respect to a longitudinal axis of the heat exchanger assembly, and wherein the top plate and the bottom plate are substantially parallel to the longitudinal axis of the heat exchanger assembly.

12. A system, comprising:
a heat exchanger assembly including a top plate, a fluid inlet and a fluid outlet, a bottom plate coupled to the top plate, a first perforated plate and a second perforated plate positioned between the top plate and the bottom plate, the first perforated plate having a topside facing the top plate and including perforations shaped to generate an impingement jet onto the top plate, and the second perforated plate having an underside facing the bottom plate and including perforations shaped to generate an impingement jet onto the bottom plate, wherein the first perforated plate includes a lip that forms a rim along a complete perimeter of the first perforated plate, and
an electronic module adjacent a bottom of the bottom plate,
wherein the first perforated plate and the second perforated plate are each inclined with respect to a longitudinal axis of the heat exchanger assembly and each other.

13. The system of claim 12 , further comprising one or more plates positioned intermediate the first perforated plate and the second perforated plate, wherein the first perforated plate and the second perforated plate are vertically stacked such that the second perforated plate is positioned intermediate the bottom plate and the one or more plates, and the first perforated plate is positioned intermediate the one or more plates and the top plate.

14. The system of claim 13 , wherein the second perforated plate is inclined such that the second perforated plate is closer to the bottom plate at a first side of the heat exchanger assembly than at a second side of the heat exchanger assembly, and wherein the first perforated plate is inclined such that the first perforated plate is closer to the top plate at the first side of the heat exchanger assembly than at the second side of the heat exchanger assembly.

15. The system of claim 12 , wherein the perforated plate is substantially flat.

16. The system of claim 12 , wherein the top plate and the bottom plate are substantially parallel to the longitudinal axis of the heat exchanger assembly.

17. The system of claim 12 , further comprising a fluid inlet channel captured between a first inlet surface of first perforated plate and a second inlet surface of the second perforated plate, a first fluid outlet channel captured between a first interior surface of the top plate and a first outlet surface of the first perforated plate, and a second fluid outlet channel captured between a second interior surface of the bottom plate and a second outlet surface of the second perforated plate.

18. The system of claim 12 , wherein the fluid inlet and the fluid outlet are part of the top plate.

19. The system of claim 12 , wherein the first perforated plate and the second perforated plate are mirror oriented to generate the impingement jet onto the top plate and the impingement jet onto the bottom plate.
