Abstract
A heat exchanger includes a cooling air conduit having multiple baffles, a hot air conduit having multiple passes through the cooling air conduit and forming multiple intersections with the baffles, and multiple perforations extending through the baffles. A cooling air flow passes through the baffles, rather than strictly between the baffles, and improves heat-transfer characteristics of the heat exchanger.
Claims11
A heat exchanger comprising:
- a cooling air conduit having at least one baffle;
- a hot air conduit having multiple passes through the cooling air conduit and forming multiple intersections with the at least one baffle;
- and
- multiple perforations extending through the at least one baffle, each perforation having an inlet, an outlet, and a passage connecting the inlet and the outlet, with the inlet and the outlet located on the same side of the at least one baffle, and the outlet located downstream of the inlet, wherein the multiple perforations are formed in pairs on opposite sides of the at least one baffle, and the at least one baffle comprises opposing winglets, which define a portion of the respective passage for each of the pairs of multiple perforations such that the respective passage extends under the respective winglet before extending toward the respective outlet.

A heat exchanger comprising:
- a first air conduit having at least one baffle, arranged parallel to a streamline through the first air conduit;
- a second air conduit comprising multiple passes extending through the first air conduit, the multiple passes arranged perpendicular to the streamline, and forming multiple intersections with the at least one baffle;
- and
- multiple perforations extending through the at least one baffle, each perforation having an inlet, an outlet, and a passage connecting the inlet and the outlet, with the inlet and the outlet located on the same side of the at least one baffle, and the outlet located downstream of the inlet, wherein the multiple perforations are formed in pairs on opposite sides of the at least one baffle, and the at least one baffle comprises opposing winglets, which define a portion of the respective passage for each of the pairs of multiple perforations such that the respective passage extends under the respective winglet before extending toward the respective outlet.
