Abstract
A heat exchanger assembly includes an inlet manifold that is configured to receive a working fluid, a plurality of microtube assemblies that define corresponding plurality passages for the working fluid and an outlet manifold that is configured to exhaust the working fluid. The plurality of microtube assemblies include a one-piece unitary structure that has a web portion that extends between at least a first microtube portion and a second microtube portion.
Claims12
A heat exchanger assembly comprising:
- an inlet manifold configured to receive a first working fluid;
- a plurality of microtube assemblies that define a corresponding plurality passages for receiving the first working fluid from the inlet manifold, wherein each of the plurality of microtube assemblies comprise a one-piece unitary structure having a first web portion extending between a first microtube portion, a second microtube portion, and a second web portion extending outward from one of the first microtube portion and the second microtube portion and a third microtube portion, wherein the third microtube portion includes a third inner diameter that is different than a first inner diameter of the first microtube portion and a second inner diameter of the second microtube portion;
- and
- an outlet manifold configured to receive and exhaust the first working fluid from the plurality of passages.

A heat exchanger assembly comprising:
- an inlet manifold configured to receive a first working fluid;
- an outlet manifold spaced apart from the inlet manifold;
- and
- a plurality of microtube assemblies that define corresponding plurality passages for the first working fluid between the inlet manifold and the outlet manifold,
- wherein each of the plurality of microtube assemblies comprise a one-piece unitary structure having a first web portion extending between a first microtube portion and a second microtube portion, a third microtube portion and a second web portion extending between the third microtube portion and one of the first microtube portion and the second microtube portion, wherein the third microtube portion includes a third inner diameter that is different than a first inner diameter of the first microtube portion and a second inner diameter of the second microtube portion;
- and
- the plurality of microtube assemblies are spaced apart from each other in a first direction transverse to a longitudinal length and a second direction transverse to the longitudinal length.

A method of assembling a heat exchanger comprising the steps of:
- forming a plurality of microtube assemblies as a one-piece unitary structure having a first web portion extending between a first microtube portion and a second microtube portion, and a second web portion extending between one of the first microtube portion and the second microtube portion and a third microtube portion, wherein forming the plurality of microtube assemblies comprises extruding the first web portion, the second web portion, the first microtube portion, the second microtube portion, and the third microtube portion without any formed seams or joints and the third microtube portion has a third inner diameter that is different than a first inner diameter of the first microtube portion and a second inner diameter of the second microtube portion;
- attaching a first end of each of the plurality of microtube assemblies to an inlet manifold;
- and
- attaching a second end of each of the plurality of microtube assembles to an outlet manifold.
