Abstract

A manifold for a heat exchanger assembly includes a body with a first end disposed opposite a second end, and a top surface disposed opposite a bottom surface. A first side surface extends between the top and bottom surfaces, and a second side surface extends between the top and bottom surfaces opposite the first side surface. A first plurality of chambers is formed in the body with each chamber of the first plurality of chambers being spaced apart from one another between the first end and the second end of the body. A second plurality of chambers is formed in the body with each chamber of the second plurality of chambers being spaced apart from one another between the first end and the second end of the body.

First claim

The invention claimed is:

1. A manifold for a heat exchanger assembly, the manifold comprising:
a body comprising:
a first end disposed opposite a second end;
a top surface disposed opposite a bottom surface;
a first side surface extending between the top surface and the bottom surface;
a second side surface extending between the top surface and the bottom surface opposite the first side surface;
a first plurality of chambers formed in the body, wherein each chamber of the first plurality of chambers extends from the top surface to the bottom surface and extends between the first side surface and an intermediate plane disposed between the first side surface and the second side surface, and wherein each chamber of the first plurality of chambers is spaced apart from one another between the first end and the second end of the body; and
a second plurality of chambers formed in the body, wherein each chamber of the second plurality of chambers extends from the top surface to the bottom surface and extends between the second side surface and the intermediate plane, and wherein each chamber of the second plurality of chambers is spaced apart from one another between the first end and the second end of the body,
wherein the top surface is parallel to the bottom surface, and the first side surface extends from the bottom surface toward the top surface at an angle selected from the range of approximately 30 degrees to approximately 45 degrees; and
a plate disposed on the top surface of the body.

2. The manifold of claim 1 , wherein the second side surface extends from the bottom surface toward the top surface at an angle selected from the range of approximately 30 degrees to approximately 45 degrees.

3. The manifold of claim 1 , wherein each chamber of the first plurality of chambers comprises:
a first opening extending through the bottom surface; and
a second opening extending through the bottom surface,
wherein the first opening of each chamber of the first plurality of chambers is configured to receive a mini-channel tube, and
wherein the second opening of each chamber of the first plurality of chambers is configured to receive a mini-channel tube.

4. The manifold of claim 3 , wherein each chamber of the second plurality of chambers comprises:
a first opening extending through the bottom surface; and
a second opening extending through the bottom surface,
wherein the first opening of each chamber of the second plurality of chambers is configured to receive a mini-channel tube, and
wherein the second opening of each chamber of the second plurality of chambers is configured to receive a mini-channel tube.

5. The manifold of claim 4 , wherein each chamber of the first plurality of chambers is aligned with a chamber of the second plurality of chambers between the first side surface and the second side surface.

6. The manifold of claim 5 , wherein the body of the manifold further comprises:
a plurality of grooves formed in the top surface of the body such that each groove extends from the first side surface to the second side surface,
wherein each groove of the plurality of grooves is disposed between two chambers of the first plurality of chambers and two chambers of the second plurality of chambers.

7. The manifold of claim 6 , wherein the plate comprises:
a plurality of slots formed in the plate,
wherein each slot of the plurality of slots is positioned over one groove of the plurality of grooves.

8. A heat exchanger assembly comprising the manifold of claim 1 , wherein the heat exchanger assembly comprises:
a second manifold disposed opposite the manifold such that the bottom surface of the manifold faces a bottom surface of the second manifold; and
a plurality of mini-channel tubes extending between the manifold and the second manifold,
wherein each chamber of the first plurality of chambers of the manifold is connected to no more than two mini-channel tubes of the plurality of mini-channel tubes, and
wherein each chamber of the second plurality of chambers of the manifold is connected to no more than two mini-channel tubes of the plurality of mini-channel tubes.

9. A manifold for a heat exchanger assembly, the manifold comprising:
a body comprising:
a first end disposed opposite a second end;
a top surface disposed opposite a bottom surface;
a first side surface extending between the top surface and the bottom surface;
a second side surface extending between the top surface and the bottom surface opposite the first side surface;
a first plurality of chambers formed in the body, wherein each chamber of the first plurality of chambers extends from the bottom surface towards the top surface and extends between the first side surface and an intermediate plane disposed between the first side surface and the second side surface, and wherein each chamber of the first plurality of chambers is spaced apart from one another between the first end and the second end of the body; and
a second plurality of chambers formed in the body, wherein each chamber of the second plurality of chambers extends from the bottom surface towards the top surface and extends between the second side surface and the intermediate plane, and wherein each chamber of the second plurality of chambers is spaced apart from one another between the first end and the second end of the body,
wherein the top surface is parallel to the bottom surface, and the first side surface extends from the bottom surface toward the top surface at an angle selected from the range of approximately 30 degrees to approximately 45 degrees.

10. The manifold of claim 9 , wherein each chamber of the first plurality of chambers and each chamber of the second plurality of chambers extends through both the top surface and the bottom surface of the body.

11. The manifold of claim 10 , wherein the manifold further comprises:
a plate disposed on the top surface of the body.

12. The manifold of claim 11 , wherein each chamber of the first plurality of chambers is configured to be connected to no more than two mini-channel tubes proximate the bottom surface, and each chamber of the second plurality of chambers is configured to be connected to no more than two mini-channel tubes proximate the bottom surface.

13. The manifold of claim 12 , wherein the manifold further comprises:
a fluid channel extending generally parallel to the body, wherein the fluid channel comprises:
a first end disposed opposite a second end;
a fluid channel bottom surface; and
a plurality of openings formed in the fluid channel bottom surface, wherein each opening of the plurality of openings is configured to receive no more than one mini-channel tube.
