These systems tend to require continual improvement in heat transfer performance, reductions in pressure loss, and reductions in size and weight. Heat exchangers can include manifolds leading into and/or out of the heat exchanger core. These manifolds can direct fluid flow into and out of the heat exchanger core and can cause a pressure drop between an inlet pipe and the heat exchanger core.
- Such conventional methods and systems have generally been considered satisfactory for their intended purpose. However, there is still a need in the art for systems and methods that allow for improved heat exchangers. The present disclosure provides a solution for these problems.
- A heat exchanger includes a vane positioned between an inlet and an outlet of a heat exchanger manifold. The vane includes a leading edge proximate the inlet and a trailing edge proximate the outlet. The vane includes opposing first and second surfaces between the leading and trailing edges. The first and second surfaces are porous to provide fluidic communication between the first surface and the second surface to resist fluid separation along the first surface and/or the second surface to minimize fluid pressure drop between the inlet and the outlet of the manifold.
- A flow path can be defined between the inlet and the outlet of the heat exchanger manifold. The inlet can define an inlet axis substantially parallel to the flow path at the inlet. The outlet can define an outlet axis angled with respect to the inlet axis.
- In accordance with some embodiments, the porosity of the vane may be defined by at least one of a plurality of apertures.

- The first surface can be a concave surface and the second surface can be a convex surface.
- The heat exchanger can include a heat exchanger core operatively connected to and in fluid communication with the outlet of the manifold.
- The heat exchanger can include a second-manifold vane positioned between an inlet and an outlet of a second heat exchanger manifold. The inlet of the second heat exchanger manifold can be operatively connected to an outlet of the heat exchanger core.
- The second heat exchanger manifold can define a second-manifold flow path between the inlet and the outlet of the second heat exchanger manifold. The inlet of the second heat exchanger manifold can define a second-manifold inlet axis substantially parallel to the second-manifold flow path at the outlet of the heat exchanger core. The outlet of the second heat exchanger manifold can define a second-manifold outlet axis angled with respect to the second-manifold inlet axis.
- The second-manifold vane can include a leading edge proximate the outlet of the heat exchanger core and a trailing edge proximate the outlet of the second heat exchanger manifold. The second-manifold vane can include porous first and second surfaces, similar to the vane describe above.
- The porosity of the second-manifold vane can be defined by apertures.

For purposes of explanation and illustration, and not limitation, a perspective view of an exemplary embodiment of a heat exchanger in accordance with the disclosure is shown in
Fig. 1 and is designated generally byreference character 100. Other embodiments ofheat exchanger 100 in accordance with the disclosure, or aspects thereof, are provided inFigs. 2-6 , as will be described. The heat exchangers described herein provide for reduced fluid pressure drop and increased flow uniformity as compared with traditional heat exchangers. - As shown in
Fig. 1 , aheat exchanger 100 includesvanes 102 positioned between aninlet 104 and anoutlet 106 of aheat exchanger manifold 108. Aflow path 110 is defined betweeninlet 104 andoutlet 106 ofheat exchanger manifold 108.Inlet 104 defines an inlet axis A substantially parallel to the flow path atinlet 104.Outlet 106 defines an outlet axis B angled with respect to inlet axis A. In an embodiment, the angle between the inlet axis A and the outlet axis B is about 90 degrees. Eachvane 102 includes a leadingedge 112proximate inlet 104 and atrailing edge 114proximate outlet 106. Eachvane 102 includes opposing first and second surfaces, 116 and 118 respectively, between leading and trailing edges, 112 and 114, respectively.First surface 116 is a concave surface andsecond surface 118 is a convex surface. It is contemplated thatmanifold 108 can include any suitable number ofvanes 102, for example,manifold 108 can include asingle vane 102 or a plurality ofvanes 102. It is contemplated that vanes can all beporous vanes 102, as will be describe below, or the vanes can be a mixture of porous and non-porous vanes. In accordance with an embodiment, it is also contemplated both porous and non-porous sections can be included in a single vane. - With continued reference to
Fig. 1 ,heat exchanger 100 includes aheat exchanger core 122 operatively connected to and in fluid communication withoutlet 106 ofmanifold 102. It is contemplated thatheat exchanger core 122 can be a plate-fin heat exchanger core, a counter-flow heat exchanger core, or any other suitable heat exchanger core.Heat exchanger 100 includes a second-manifold vane 102' positioned between an inlet 104' and an outlet 106' of a second heat exchanger manifold 108'. Inlet 104' of second heat exchanger manifold 108' is connected to anoutlet 107 ofheat exchanger core 122. Second heat exchanger manifold 108' defines a second-manifold flow path 110' between inlet 104' and outlet 106' of second heat exchanger manifold 108'. Inlet 104' of the second heat exchanger manifold 108' defines a second-manifold inlet axis C substantially parallel to the second-manifold flow path atoutlet 107 ofheat exchanger core 122. Outlet 106' of second heat exchanger manifold 108' defines a second-manifold outlet axis D angled with respect to second-manifold inlet axis C. Theheat exchanger 100 being configured, in one embodiment, so that the flow out of the outlet 106' along axis D is substantially 180 degrees to the flow into theinlet 104 along axis A. - While
vanes 102 and 102' are shown with varying thicknesses, those skilled in the art will readily appreciate thatvanes 102 and/or 102' can be uniform in thickness. It is contemplated thatmanifolds 108 and/or 108' can have a variety of suitable shapes, for example, they can be semi-hemispherical, include a diffuser, or be any other suitable shape or variation depending on the design space provided.Manifolds 108 and/or 108' andvanes 102 and/or 102' can be made from a variety of suitable metals or alloys thereof, such as, nickel, copper, titanium, steel, and/or aluminum. In accordance with some embodiments, it is contemplated that the leading and trailing edges ofvanes 102 and/or 102' can begin and end anywhere, as long as at least a portion of a given vane is positioned between the inlet and the outlet. It is also contemplated that the vanes may all be of the same length and spacing, or may have different lengths and spacing to achieve the desired flow distribution with minimal pressure drop. - As shown in
Fig. 2 , concave and convex surfaces, 116 and 118, respectively, of eachvane 102, are porous to provide fluidic communication betweenconcave surface 116 toconvex surface 118, shown schematically by arrows. The fluid flow fromconcave surface 116 toconvex surface 118 acts to resist fluid separation on along convex 118 surface and minimizes fluid pressure drop betweeninlet 104 andoutlet 106 ofmanifold 108. With traditional heat exchanger vanes, fluid flow over the convex side of the vane tends to separate and can result increased pressure loss across the vane, and ultimately can result in increased pressure drop between the inlet and outlet of the manifold. The porosity ofvane 102 acts as a flow control device to minimize separation fromconvex surface 118 and reduce the pressure loss acrossvane 102 inmanifold 108 while still providing the desired flow distribution intoheat exchanger core 122. In accordance with the embodiment inFig. 2 , the porosity invane 102 is achieved usingapertures 120 between concave and convex surfaces, 116 and 118, respectively. - As shown in
Figs. 3-6 , it is contemplated that the porosity of vanes can be achieved with a variety of suitable geometries, for example, vanes can be a perforated sheet with either uniform or non-uniformly spaced holes, slits, or other features. In accordance with some embodiments,vanes Figs. 3 and 4 , respectively. In accordance with the embodiment ofFig. 5 ,vanes 402 resemble the construction of open-cell foam and/or reticulated foam, where pores of the foam allow flow from one surface to the other. As shown in the embodiment ofFig. 6 ,vanes 502 include a wire mesh structure, similar to a metal screen. - With reference now to
Figs. 1 and 2 , each of the second-manifold vanes 102' include a respective leading edge 112'proximate outlet 107 ofheat exchanger core 122 and a respective trailing edge 114' proximate outlet 106' of second heat exchanger manifold 108'. Each second-manifold vane 102' includes respective porous concave and convex surfaces, 116' and 118', respectively, similar tovane 102 describe above. For example, one or more of second-manifold vanes 102' can include apertures, similar toapertures 120 invane 102, described above. It is contemplated that manifold 108' can include any suitable number of vanes 102', for example, manifold 108' can include a single vane 102' or a plurality of vanes 102'. It is contemplated that vanes 102' can all be porous vanes, or vanes 102' can be a mixture of porous and non-porous vanes. In accordance with an embodiment, it is also contemplated that both porous and non-porous sections can be included in a single vane. - In accordance with another aspect, a method of manufacturing a vane,
e.g. vanes 102 and/or 102', for a heat exchanger,e.g. heat exchanger 100, includes forming a vane body having a leading edge and a trailing edge, e.g. leading and trailing edges, 112/112' and 114/114', respectively, with a concave surface and an opposing convex surface, e.g. concave andconvex surfaces 116/116' and 118/118', respectively, between the leading and trailing edges using additive manufacturing, for example, direct metal laser sintering. It is contemplated that the vanes can be formed in conjunction with their respective heat exchanger manifolds, e.g.heat exchanger manifolds 108 and/or 108'. - While
vanes 102 and 102' are shown and described herein as having an arcade geometry, it is contemplated thatvanes 102 and 102' do not have to be continuously curved.Vanes 102 and 102' can include straight sections, be entirely straight, or can create an s-curve, depending on the orientation of the inlet manifold, the core and the outlet manifold. Additionally, it is contemplated that while the flow path atinlet 104 is shown at ninety degrees with respect tocore 122,inlet 104 can be at a variety of angles with respect tocore 122. For example, they can be in direct alignment or at an angle less than or more then ninety degrees. This similarly can apply to the angle betweencore 122 and outlet 106' of second heat exchanger manifold 108'. - The methods and systems of the present disclosure, as described above and shown in the drawings, provide for heat exchanger manifolds with vanes having superior properties including reduced pressure drop and flow uniformity. While the apparatus and methods of the subject disclosure have been shown and described with reference to preferred embodiments, those skilled in the art will readily appreciate that changes and/or modifications may be made thereto without departing from the scope of the subject claims.
