Wavy adjacent passage heat exchanger core and manifold

A heat exchanger includes a first fluid inlet, a first fluid outlet, a second fluid inlet, a second fluid outlet, and a core section. The core section includes a plurality of first fluid passages through which a first fluid flows. And a plurality of second fluid passages through which a second fluid flows to exchange thermal energy with the first fluid. The first fluid passage and the second fluid passage extend non-linearly along a length of the first fluid passage and the second fluid passage between a first core end and a second core end opposite the first core end. A manifold is operably connected to the plurality of first fluid passages. The manifold includes a plurality of lateral passages intersecting the plurality of first fluid passages. A length of the plurality of lateral passages varies according to a distance from a fluid upstream end of the core section. 一种热交换器包括第一流体入口、第一流体出口、第二流体入口、第二流体出口和芯部段。所述芯部段包括多个第一流体通路，第一流体流过所述多个第一流体通路；以及多个第二流体通路，第二流体流过所述多个第二流体通路以与所述第一流体交换热能。所述第一流体通路和所述第二流体通路在第一芯端和与所述第一芯端
