A condenser having passages of varying geometry for cooling of fluid. The condenser apparatus includes substantially parallel tubes each defining a channel and having an inlet at a first end and an outlet at a second end, the first end having a greater hydraulic diameter than the second end. Inlet and outlet manifolds are provided. The tubes may be oriented substantially vertically with the inlets above the respective outlets. A heat exchanger core comprises the tubes and substantially horizontally oriented fin material connecting the tubes. The tubes may receive a relatively higher temperature vapor or vapor and liquid mixture into the inlets of the tubes, around the tubes coolant flows substantially horizontally to remove heat from the tubes, and relatively cooler saturated liquid is discharged from the outlets. In one embodiment, the tube's channel splits into multiple channels to reduce the hydraulic diameter and increase the surface area ratio.

1. A condenser apparatus, comprising: a heat exchanger comprising a heat exchanger core, the heat exchanger core comprising a plurality of substantially parallel tubes, each of the tubes defining a channel and having an inlet at a first end and an outlet at a second end, wherein the tubes are arranged in a matrix comprising a plurality of rows and a plurality of columns of the tubes; an inlet manifold, the inlet of each of the tubes connected to the inlet manifold, the inlet manifold configured to receive a fluid into the condenser apparatus and then distribute the fluid to each of the tubes at the inlets; and an outlet manifold, the outlet of each of the tubes connected to the outlet manifold, the outlet manifold configured to receive the fluid from each of the tubes at the outlets and then discharge the fluid from the condenser apparatus; wherein each of the tubes comprise a longitudinal axis, the longitudinal axis being oriented substantially vertically with each of the inlets located above the respective outlets such that the inlet manifold is located above the outlet manifold; Wherein each of the tubes comprises a plurality of parallel portions which are parallel to the longitudinal axis, and a plurality of tapered portions, the tapered portions interposing adjacent parallel portions of the parallel portions such that the parallel and tapered portions alternate along the longitudinal axis; wherein the first end of each of the tubes is one of the parallel portions, and the second end of each of the tubes is also one of the parallel portions; wherein each of the tapered portions has a first side connected to one of the parallel portions and a second side connected to another one of the parallel portions, the first side being closer than the second side to the first end of the respective tube; and wherein each of the tubes has a hydraulic diameter at each of the parallel portions, each of the tapered portions tapers along the longitudinal axis to transition between the hydraulic diameter of the parallel portion connected to the first side and the hydraulic diameter of the parallel portion connected to the second side, and the hydraulic diameter of the parallel portion connected to the first side is greater than the hydraulic diameter of the parallel portion connected to the second side. 2. The condenser apparatus of claim 1, further comprising fins connected to the tubes. 3. The condenser apparatus of claim 1, wherein the heat exchanger core is configured such that the tubes receive a vapor or vapor and liquid mixture having a first temperature into the inlets of the tubes, and a coolant flows around the tubes substantially perpendicular to the longitudinal axis of the tubes to remove heat from the tubes, and saturated liquid having a second temperature is discharged from the outlets, wherein the second temperature is lower than the first temperature. 4. The condenser apparatus of claim 1, wherein a cross-section of each tube is circular. 5. The condenser apparatus of claim 1, further comprising a pump located in the outlet manifold. 6. The condenser apparatus of claim 1, further comprising fins connected to each of the tubes, each of the fins comprising a plurality of notches. 7. The condenser apparatus of claim 1, further comprising a coolant flowing around the tubes to remove heat from the tubes, wherein the coolant is a liquid or air. 8. The condenser apparatus of claim 1, wherein a cross-section of each tube is elliptical. 9. The condenser apparatus of claim 1, wherein a cross-section of each tube is a shape other than circular. 10. The condenser apparatus of claim 1, further comprising a coolant flowing around the tubes to remove heat from the tubes.
