Abstract

A heat-exchanger module that conveys a fluid through one or more heat exchangers with little or no pressure drop is presented. The heat-exchanger module comprises a first manifold that smoothly channels the fluid from a fluid source to each of the heat exchangers. The heat-exchanger module further comprises a second manifold that smoothly channels the fluid from the heat exchangers to a fluid sink. The manifolds are dimensioned and arranged to mitigate development of pressure drops in the fluid flow.

First claim

What is claimed is:

1. A heat-exchanger module comprising:
a plurality of heat exchangers configured to convey a first fluid;
a first manifold, the first manifold comprising:
an inlet port having a first cross-sectional area;
a first channel having a first end with the first cross-sectional area coupled to the inlet port and a second end with a second cross-sectional area smaller than the first cross-sectional area, the first channel comprising:
a first sidewall that extends perpendicularly with respect to the first cross-sectional area of the first end of the first channel and the second cross-sectional area of the second end of the first channel and parallel with respect to a direction of fluid flow from the first end to the second end of the first channel; and
a first turning vane opposite the first sidewall that extends from the first end to the second end of the first channel such that a cross-sectional area that is perpendicular to the first sidewall reduces monotonically in the direction of fluid flow from the first cross-sectional area at the first end of the first channel to the second cross-sectional area at the second end of the first channel, wherein the first end of the first channel is coupled to the inlet port of the heat-exchanger module; and

a second channel dimensioned and arranged to fluidically couple with each of the plurality of heat exchangers, the second channel fluidically coupled with the first channel at the second end of the first channel, the second channel comprising:
a second sidewall coplanar with the first sidewall of the first channel; and
a third sidewall opposite the second sidewall and coupled to the first turning vane of the first channel, the third sidewall forming a plurality of apertures configured to fluidically couple the second channel with the plurality of heat exchangers and

a second manifold comprising:
an outlet port having a third cross-sectional area;
a third channel having a first end with a third cross-sectional area coupled to the outlet port and a second end with a fourth cross-sectional area smaller than the third cross-sectional area, the third channel comprising:
a fourth sidewall that extends perpendicularly with respect to the third cross-sectional area of the first end of the third channel and the fourth cross-sectional area of the second end of the third channel and parallel with respect to a direction of fluid flow from the second end to the first end of the third channel; and
a second turning vane opposite the fourth sidewall that extends from the first end to the second end of the third channel such that a cross-sectional area that is perpendicular to the fourth sidewall increases monotonically in the direction of fluid flow from the fourth cross-sectional area at the second end of the third channel to the third cross-sectional area at the first end of the third channel, wherein the first turning vane is parallel to the second turning vane; and

a fourth channel dimensioned and arranged to fluidically couple with each of the plurality of heat exchangers, the fourth channel fluidically coupled with the third channel at the second end, the fourth channel comprising:
a fifth sidewall coplanar with the fourth sidewall of the third channel; and
