High Efficiency UV LED Reactor for Flow Treatment and Sterilization of Fluids

A UV LED reactor configured to perform a treatment process on a fluid comprising:

• a housing having an inlet for receiving the fluid, a reactor chamber for treating the fluid, and an outlet for discharging the fluid;
• a UV LED module mounted to the housing comprising:
• a base;
• a UV LED emitter on the base configured to emit UV radiation having a selected wavelength range, a selected beam angle and a selected energy into the reactor chamber, and
• a heatsink in thermal communication with the base configured to dissipate heat generated by the UV LED emitter having a surface in contact with the fluid in the reactor chamber configured to dissipate heat generated by the UV LED emitter into the fluid;
• and
• a UV transparent inner tube mounted to the inlet in flow communication with the outlet configured to direct a fluid flow path in a first direction towards the UV LED module and then in a second direction away from the UV LED module.
