Condenser apparatus and method

A condenser apparatus, comprising:

• a plurality of substantially parallel tubes, each tube having an inlet at a first end and an outlet at a second end, the first end defining a first channel and the second end defining a plurality of channels, with the first channel splitting into the plurality of channels between the first end and the second end, the first end having a greater hydraulic diameter than the second end;
• an inlet manifold at the inlets of the tubes for distributing flow to the inlets;
• and
• an outlet manifold at the outlets of the tubes for receiving flow from the outlets.

A method of condensing a hot vapor or vapor and liquid mixture to a liquid, the method comprising:

• discharging a relatively higher temperature vapor or vapor and liquid mixture flow from an inlet manifold and into a plurality of substantially parallel tubes, each tube 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;
• causing the relatively higher temperature vapor or vapor and liquid mixture to flow through the tubes and to condense to be saturated liquid;
• and
• receiving the saturated liquid in an outlet manifold at the outlets of the tubes.

A condenser apparatus, comprising:

• a heat exchanger comprising a heat exchanger core, the heat exchanger core comprising a plurality of substantially parallel tubes, each tube having an inlet at a first end and an outlet at a second end, the first end defining a first channel and the second end defining a plurality of channels, with the first channel splitting into the plurality of channels between the first end and the second end, the first end having a greater hydraulic diameter than the second end;
• 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 discharged the fluid from the condenser apparatus.
