Evaporative Spray Cooling Technology

RINI's patented ESC technology employs nozzles to impinge liquid droplets onto heated surfaces such as laser diode arrays (LDA). A thin liquid layer is evaporated in a two-phase heat-transfer process. The modular ESC nozzle approach uses a variety of coolants and is scalable from 1 cm2 to 64 cm2. RINI's laser ESC can be designed to integrate with laser diodes or solid-state gain materials. The resulting LDA performances are equivalent to micro-channel cooling but with superior SWaP and a 12X reduction in coolant flow rate. The end result is smaller pumps, less power consumption, reduced fluid inventory and more efficient heat exchangers -- enabling benefits for tactical laser deployments.
