Computer systems having heat exchangers for cooling computer components are disclosed herein. The computer systems include a computer cabinet having an air inlet, an air outlet spaced apart from the air inlet, and a plurality of computer module compartments positioned between the air inlet and the air outlet. The air inlet, the air outlet, and the computer module compartments define an air flow path through the computer cabinet. The computer systems also include a heat exchanger positioned between two adjacent computer module compartments. The heat exchanger includes a plurality of heat exchange elements canted relative to the air flow path.

A computer system, comprising: a computer cabinet having a plurality of computer module compartments positioned between an air inlet and an air outlet, wherein the air inlet, the air outlet, and the computer module compartments define an air flow path through the computer cabinet;a heat exchanger
1. A computer system, comprising: a computer cabinet having a plurality of computer module compartments positioned between an air inlet and an air outlet, wherein the air inlet, the air outlet, and the computer module compartments define an air flow path through the computer cabinet;a heat exchanger positioned between two adjacent computer module compartments, the heat exchanger including: an inlet manifold having an inlet divider separating the inlet manifold into a first inlet volume and a second inlet volume;an outlet manifold spaced apart from the inlet manifold and having an outlet divider separating the outlet manifold into a first outlet volume and a second outlet volume; anda plurality of heat exchange elements extending between the inlet manifold and the outlet manifold, wherein each individual heat exchange element includes a plurality of internal channels extending from a first end portion to a second end portion;wherein the inlet divider cooperates with the first end portion and the outlet divider cooperates with the second end portion to separate the internal channels of each individual heat exchange element into a first channel portion in fluid communication with the first inlet volume and the first outlet volume, and a second channel portion in fluid communication with the second inlet volume and the second outlet volume;wherein the first inlet volume, the first channel portion, and the first outlet volume form a first flow path, and wherein the second inlet volume, the second channel portion, and the second outlet volume form a second flow path in fluid isolation from the first flow path. 2. The computer system of claim 1 wherein the first and second flow paths are arranged sequentially along the air flow path. 3. A computer system, comprising: a computer cabinet having a plurality of computer module compartments positioned between an air inlet and an air outlet, wherein the air inlet, the air outlet, and the computer module compartments define an air flow path through the computer cabinet; anda heat exchanger positioned between two adjacent computer module compartments, the heat exchanger including: a first flow path and a second flow path in fluid isolation from the first flow path;an inlet manifold having an inlet divider separating the inlet manifold into a first inlet volume and a second inlet volume;an outlet manifold having an outlet divider separating the outlet manifold into a first outlet volume and a second outlet volume; anda plurality of heat exchange elements positioned between the inlet manifold and the outlet manifold, wherein each of the individual heat exchange elements includes a passage portion having a first channel portion and a second channel portion, wherein the first channel portion is in fluid communication with the first inlet volume and the first outlet volume, and wherein the second channel portion is in fluid communication with the second inlet volume and the second outlet volume. 4. The computer system of claim 3 wherein the first inlet volume, the first channel portion, and the first outlet volume at least partially define the first flow path, and wherein the second inlet volume, the second channel portion, and the second outlet volume at least partially define the second flow path. 5. The computer system of claim 3, further comprising a first working fluid portion in the first flow path and a second working fluid portion in the second flow path, and wherein the first working fluid portion and the second working fluid portion have different physical characteristics. 6. The computer system of claim 5 wherein the first working fluid portion has at least one of a higher flow rate, a higher heat transfer coefficient, a lower boiling point, a higher heat of vaporization than the second working fluid portion. 7. A method for operating a computer cabinet having a plurality of computer module compartments positioned between an air inlet and an air outlet and a heat exchanger positioned between two adjacent computer module compartments, the method comprising: flowing a first working fluid portion along a first inlet volume in an inlet manifold of the heat exchanger; flowing a second working fluid portion along a second inlet volume in the inlet manifold, wherein the inlet manifold includes an inlet divider separating the inlet manifold into the first inlet volume and the second inlet volume, and wherein the first and second inlet volumes are in fluid isolation from each other; flowing the first working fluid portion from the first inlet volume along a first flow path in a first internal channel of an individual heat exchange element of the heat exchanger; flowing the second working fluid portion from the second inlet volume along a second flow path in a second internal channel of the individual heat exchange element of the heat exchanger, the first and second internal channels being in fluid isolation from each other; flowing the first working fluid portion from the first internal channel into a first outlet volume of an outlet manifold of the heat exchanger; flowing the second working fluid portion from the second internal channel into a second outlet volume of the outlet manifold, wherein the outlet manifold includes an outlet divider separating the outlet manifold into the first outlet volume and the second outlet volume, and wherein the first and second outlet volumes are in fluid isolation from each other; flowing air through the heat exchanger and past the first and second internal channels; and controlling at least one characteristic of at least one of the first and second working fluid portions. 8. The method of claim 7 wherein controlling at least one characteristic includes controlling a flow rate, a heat transfer coefficient, a boiling point, and/or a heat of vaporization of the first and/or second working fluid portions.
