Filed:

Dec 1, 2020

Appl. No.:

17/108658

Inventors:

- Cambridge MA, US
Mark Bury - Acton MA, US
Conor Doyle - Sherborn MA, US
William Kammerer - Leominster MA, US
William Flaherty - Dunstable MA, US
Ryan Fontaine - Waltham MA, US

International Classification:

F28F 25/02
F28C 1/16
F28D 3/04

Abstract:

A droplet heat exchange system is provided for that includes a heat exchange chamber, at least one injector, and at least one swirler. The chamber is configured to have gas flow through it. The injector can be configured to dispense liquid droplets into the chamber for thermal energy exchange with gas flowing through the chamber. The swirler can disposed within the chamber and can have a body configured to form a spiral gas flow that pushes liquid droplets from the injector, radially outward as gas flows across the body, thereby separating the liquid droplets from the gas flowing across the body and forming a liquid film along an inner wall of the chamber. The collector can be in fluid communication with the heat exchange chamber and configured to collect the liquid film after thermal energy exchange. The collector can be configured to direct at least some of the collected liquid film to the injector for subsequent use.
