Abstract

A side plate for use in a heat exchanger having a width dimension and a first and a second row of parallel arranged tubes extending in the direction of the width dimension. A first and a second header are arranged at one common end of the width dimension to receive the ends of the tubes in the first and second rows, respectively. The side plate includes a first body section joined to and extending from the first header, the first body section defining a first outer periphery. The side plate includes a second body section joined to and extending from the second header, the second body section defining a second outer periphery. The second outer periphery is spaced apart from the first outer periphery such that each one of the first and second body sections is allowed to more relative to the other in the direction of the width dimension.

First claim

We claim:

1. A side plate for use in a heat exchanger, the side plate comprising:
a substantially planar base section having a long dimension between opposing first and second short sides, and a short dimension between opposing first and second long sides;
a first elongated slot extending through the substantially planar base section, and oriented to be aligned with the long dimension, the first elongated slot extending in a long dimension direction from the first short side to a first terminating location positioned a fraction of the long dimension away from the first short side; and
a second elongated slot extending from the first terminating location to a second terminating location at a non-zero angle to the long dimension direction, the second terminating location being located further away from the first short side than the first terminating location,
wherein the first terminating location includes a first breaking point that separates the first elongated slot from the second elongated slot, and
wherein the second terminating location includes a second breaking point between the second elongated slot and the first long side.

2. The side plate of claim 1 , further comprising:
a bent flange joined to the substantially planar base section at the first long side; and
one or more third elongated slots extending through the bent flange from approximately the second terminating location.

3. The side plate of claim 1 , further comprising a third elongated slot extending from the first terminating location to a third terminating location at a non-zero angle to the long dimension direction, the third terminating location being located further away from the first short side than the first terminating location, wherein the third terminating location includes a third breaking point between the third elongated slot and the second long side.

4. The side plate of claim 3 , further comprising:
a first bent flange joined to the substantially planar base section at the first long side;
a second bent flange joined to the substantially planar base section at the second long side;
one or more fourth elongated slots extending through the first bent flange from approximately the second terminating location; and
one or more fifth elongated slots extending through the second bent flange from approximately the third terminating location.

5. The side plate of claim 3 , wherein the first terminating location includes a fourth breaking point that separates the first elongated slot from the third elongated slot.

6. The side plate of claim 5 , wherein the first elongated slot includes a first corner and a second corner at the first terminating location, wherein the second elongated slot includes a third corner at the first terminating location, wherein the third elongated slot includes a fourth corner at the first terminating location, wherein the first breaking point is located between the first corner and the third corner, and wherein the fourth breaking point is located between the second corner and the fourth corner.

7. The side plate of claim 5 , further comprising:
a first body section disposed over a first row of tubes of the heat exchanger;
a second body section disposed over a second row of tubes of the heat exchanger; and
a third body section disposed over the first row and the second row,
wherein the first body section includes a first periphery defined by the first elongated slot, the second elongated slot, the first breaking point, and the second breaking point,
wherein the second body section includes a second periphery defined by the first elongated slot, the second elongated slot, the third breaking point, and the fourth breaking point, and
wherein the third body section includes a third periphery defined by second elongated slot, the third elongated slot, the first breaking point, the second breaking point, the third breaking point, and the fourth breaking point.

8. The side plate of claim 3 , wherein the first elongated slot is at least partially disposed in a short dimension direction between the second elongated slot and the third elongated slot.

9. The side plate of claim 1 , wherein the fraction of the long dimension is no more than one tenth.

10. The side plate of claim 1 , wherein said angle is approximately 45 degrees.

11. The side plate of claim 1 , wherein the first elongated slot extends a first distance in the long dimension direction from the first side to the first terminating location, wherein the second elongated slot extends a second distance in a short dimension direction tranverse to the long dimension direction, and wherein the first distance is greater than the second distance.

12. The side plate of claim 1 , wherein the first elongated slot includes a plurality of first elongated slots.

13. The side plate of claim 1 , wherein the first elongated slot is at least partially located in a short dimension direction between a first row of tubes of the heat exchanger and a second row of tubes of the heat exchanger, wherein the first row of tubes in fluidly connected to the second row of tubes.

14. The side plate of claim 1 , wherein the first breaking point is offset in a short dimension direction from a center location of the side plate.

15. The side plate of claim 1 , wherein the first elongated slot includes a first corner at the first terminating location, wherein the second elongated slot includes a second corner at the first terminating location, and wherein the first breaking point is located between the first corner and the second corner.

16. The side plate of claim 1 , wherein the first terminating location includes a first corner and a second corner spaced apart from the first corner, wherein the first terminating location is at least partially located in a short dimension direction between a first row of tubes of the heat exchanger and a second row of tubes of the heat exchanger, wherein the first corner and the second corner are offset from a center location in the short dimension direction of the side plate, wherein the first corner is located between the first elongated slot and the second elongated slot, and wherein the second corner is located between the first elongated slot and a third elongated slot that extends to a second side of the side plate.

17. The side plate of claim 1 , further comprising:
a first body section disposed over a first row of tubes of the heat exchanger; and
a second body section disposed over the first row of tubes and a second row of tubes of the heat exchanger;
wherein the first body section includes a first periphery defined by a first side of the first elongated slot, a first side of the second elongated slot, the first breaking point, and the second breaking point,
wherein the second body section includes a second periphery defined by a second side of the first elongated slot, a second side of the second elongated slot, the first breaking point, and the second breaking point,
wherein the first body section is joined to a first header of the heat exchanger, and
wherein the second body section is joined to a second header of the heat exchanger.

18. The side plate of claim 1 , wherein the first elongated slot extends beyond the first breaking point extending in a first short dimension direction toward the first long side and extends beyond the first breaking point extending in an opposite, second short dimension direction toward the second long side, wherein the second elongated slot extends beyond the first breaking point extending in the first short dimension direction toward the fir
