Abstract
A fluid circuit of a heat exchanger includes a core and a first header. The core is configured to receive a fluid and includes a plurality of conduits. Each of the plurality of conduits extends along a longitudinal axis from a first end portion to a second end portion. The first header is integrally formed with and fluidly connecting the plurality of conduits. Outer walls of the plurality of conduits taper outward relative to the longitudinal axes to join the first header.
Claims16
A fluid circuit of a heat exchanger, the fluid circuit comprising:
- a core configured to receive a fluid, the core comprising a plurality of conduits, each conduit of the plurality of conduits extending along a longitudinal axis from a first end portion to a second end portion;
- and
- a first header integrally formed with and fluidly connecting the plurality of conduits wherein the first header comprises an outermost wall and an innermost wall relative to the longitudinal axes of the plurality of conduits, wherein the plurality of conduits is joined to each of the outermost wall and the innermost wall;
- wherein an outer wall of each conduit of the plurality of conduits comprises a first tapered section and a second tapered section, the first tapered section tapering outward relative to the longitudinal axis of the respective conduit to join a surface of the innermost wall outside of the first header, and the second tapered section tapering outward relative to the longitudinal axis of the respective conduit to join a surface of the outermost wall inside the first header.
