Abstract
A heat exchanger having a first core with a first end and a second end and having a first plurality of hot flow channels fluidly isolated from a first plurality of cool flow channels. The first plurality of hot flow channels and the first plurality of cool flow channels can be arranged in a first checkerboard pattern. The heat exchanger also having a first header connected to the first end of the first core, a first hot flow inlet section connected to the first plurality of hot flow channels, and a first curved portion with a first inner hot flow route that is longer than a first outer hot flow route. The first header also having a first cool flow outlet section connected to the first plurality of cool flow channels with the first cool flow outlet section being fluidly isolated from the hot flow inlet section.
Claims20
A heat exchanger comprising:
- a first core with a first end and a second end and having a first plurality of hot flow channels fluidly isolated from a first plurality of cool flow channels, the first plurality of hot flow channels and the first plurality of cool flow channels being arranged in a first checkerboard pattern;
- and
- a first header connected to the first end of the first core comprising:
- a first hot flow inlet section connected to the first plurality of hot flow channels, the first hot flow inlet section having a first curved portion with a first inner hot flow route that is longer than a first outer hot flow route;
- and
- a first cool flow outlet section connected to the first plurality of cool flow channels, the first cool flow outlet section being fluidly isolated from the first hot flow inlet section.
A heat exchanger comprising:
- a core with hot flow channels and cool flow channels, the core having a center and outer edges;
- and
- a first header connected to a first end of the core, the first header comprising:
- a hot flow inlet;
- first hot flow routes connecting the hot flow channels to the hot flow inlet, a first plurality of the first hot flow routes connecting the hot flow channels nearer the outer edges of the core to the hot flow inlet and being longer in length than a second plurality of the first hot flow routes that connect the hot flow channels nearer the center of the core to the hot flow inlet.
- two cool flow outlets;
- and
- first cool flow routes connecting the cool flow channels to one of the two cool flow outlets, a first plurality of the first cool flow routes connecting the cool flow channels nearer the outer edges of the core to one of the two cool flow outlets and being shorter in length than a second plurality of the first cool flow routes that connect the cool flow channels nearer the center of the core to one of the two cool flow outlets.
