Abstract

A plate for a heat exchanger includes a substantially planar body having a first end, a second end opposing the first end, a fluid surface, and an outer surface. A first cup extends from the outer surface of the body adjacent the first end of the body. A second cup extends from the outer surface of the body and is spaced from the second end of the body.

First claim

What is claimed is:

1. A plate for a heat exchanger comprising:
a substantially planar body having a first end, a second end opposing the first end, a fluid surface, and an outer surface, wherein a plurality of protrusions extends from the fluid surface;
a first cup extending outwardly from the outer surface of the body and spaced from the first end of the body; and
a second cup extending outwardly from the outer surface of the body adjacent the second end of the body, wherein the plurality of protrusions further comprise a plurality of guiding protrusions, a plurality of restricting protrusions, and a plurality of turbulating protrusions, the plurality of guiding protrusions configured to guide a flow of a coolant between the first cup and the second cup, the plurality of restricting protrusions configured to restrict the flow of the coolant between the first cup and the second cup, the plurality of turbulating protrusions configured to cause a turbulent flow of the coolant flowing between the first cup and the second cup, wherein the plurality of guiding protrusions is elongate and disposed about a perimeter of the second cup, wherein the plurality of guiding protrusions is disposed intermediate the second cup and a side of the body with respect to a width direction of the plate, wherein a first portion of the plurality of turbulating protrusions is disposed between adjacent ones of the plurality of guiding protrusions, wherein a second portion of the plurality of turbulating protrusions is disposed intermediate the first cup and the first end of the body, and wherein a cross-sectional shape of the turbulating protrusions is different from a cross-sectional shape of the guiding protrusions.

2. The plate of claim 1 , wherein the first cup includes an aperture configured as an inlet aperture to convey a coolant from a coolant inlet of the heat exchanger to the plate, and wherein the second cup includes an aperture configured as an outlet aperture to convey the coolant from the plate to a coolant outlet of the heat exchanger.

3. A plate and fin assembly for a heat exchanger comprising:
a plate having a fluid surface, an outer surface, a first end, a second end, a first cup extending outwardly from the outer surface, and a second cup extending outwardly from the outer surface, wherein a plurality of protrusions extends outwardly from the fluid surface, the plurality of protrusions including a plurality of elongate guiding protrusions, a plurality of restricting protrusions, and a plurality of turbulating protrusions, the plurality of guiding protrusions configured to guide a flow of a coolant between the first cup and the second cup, the plurality of restricting protrusions configured to restrict the flow of the coolant between the first cup and the second cup, the plurality of turbulating protrusions configured to cause a turbulent flow of the coolant flowing between the first cup and the second cup, wherein the plurality of guiding protrusions is disposed about a perimeter of the first cup and the second cup, wherein the plurality of guiding protrusions is disposed intermediate the first cup and each of a pair of sides of the body and intermediate the second cup and each of the sides of the body with respect to a width direction of the plate, wherein a first portion of the plurality of turbulating protrusions is disposed between adjacent ones of the plurality of guiding protrusions, wherein a second portion of the plurality of turbulating protrusions is disposed intermediate the first cup and the first end of the body, and wherein a cross-sectional shape of the turbulating protrusions is different from a cross-sectional shape of the guiding protrusions; and
a fin engaging the outer surface of the plate, the fin having a louvre region and a non-louvre region, the non-louvre region engaging the plate adjacent the first cup with respect to a width of the plate, the louvre region engaging the plate intermediate the first cup and the second cup with respect to a length of the plate.

4. The plate and fin assembly of claim 3 , wherein the first cup includes an aperture configured as an inlet aperture to convey a coolant from a coolant inlet of the heat exchanger to the plate, wherein the second cup includes an aperture configured as an outlet aperture to convey the coolant from the plate to a coolant outlet of the heat exchanger, and wherein the plate is substantially planar.

5. The plate and fin assembly of claim 4 , wherein the first cup is spaced from the first end of the plate and the second cup is spaced from the second end of the plate.

6. The plate and fin assembly of claim 4 , wherein the first cup is spaced from the first end of the plate and the second cup is disposed adjacent the second end of the plate.

7. The plate and fin assembly of claim 3 , wherein each of the first cup and the second cup has a collar, and wherein a radius of the collar is variable.

8. The plate and fin assembly of claim 3 , wherein at least one of the plurality of restricting protrusions extends about a perimeter of one of the first cup and the second cup.

9. The plate and fin assembly of claim 3 , wherein the plurality of guiding protrusions extends in an arcuate shape.

10. The plate and fin assembly of claim 3 , wherein the first cup and the second cup each include a planar rim spaced from the outer surface of the plate and a collar extending outwardly from the outer surface of the plate and terminating at the planar rim.

11. The plate and fin assembly of claim 3 , wherein the fin includes a first cutout portion configured to receive the first cup and a second cutout portion configured to receive the second cup.

12. The plate and fin assembly of claim 3 , wherein the plate is symmetric about a widthwise direction extending through a center of a length of the plate.

13. The plate and fin assembly of claim 3 , wherein the plate is asymmetric about a widthwise direction extending through a center of a length of the plate.

14. The plate and fin assembly of claim 3 , wherein the non-louvre region is divided into a first non-louvre portion and a second non-louvre portion, wherein a first portion of the louvre region is disposed intermediate the first non-louvre portion and the second non-louvre portion.

15. The plate and fin assembly of claim 14 , wherein the first portion of the louvre region engages the outer surface of the plate intermediate the first cup and the second cup and a second portion of the louvre region engages the outer surface of the plate intermediate the first cup and the first end.

16. A plate and fin assembly for a heat exchanger comprising:
a plate having a fluid surface, an outer surface, a first end, a second end, a first cup, and a second cup, the plate including a plurality of protrusions extending outwardly from the fluid surface of the plate, wherein the plurality of protrusions includes a plurality of elongate guiding protrusions formed adjacent each of the first cup and the second cup and configured to guide a flow of a coolant between the first cup and the second cup, wherein the plurality of protrusions includes a plurality of restricting protrusions configured to restrict the flow of the coolant between the first cup and the second cup, wherein the plurality of protrusions includes a plurality of turbulating protrusions configured to cause a turbulent flow of the coolant flowing between the first cup and the second cup, and wherein the plurality of guiding protrusions extends in an arcuate shape, the plurality of restricting protrusions is substantially U-shaped in cross-section, and the plurality of turbulat
