Patented Cool

Cool Technologies’ radial vent methods receive patent

Cool Technologies, Inc., received a US patent (no. 9,543,809) on February 24 for its radial vent heat pipe system as well as a notice of allowance for a patent in Mexico.

“Cooling technologies developed in the 1970s are still the standard in many electric motor and generator designs today,” Tim Hassett, Cool Technologies’ CEO, said in a press release February 28, “In an industry which relies on incremental modifications to improve its products, real innovation is big news.” The company specializes in mobile power generation, energy efficiency, and heat removal technologies.

The radial vent technology cools and increases the power density of rotating equipment. By rapidly transferring heat from core of the electric motor to vents where it is expelled, the patent is expected to increase the potential output or power density of the machine by 10 to 20%. (Currently, to achieve an equivalent increase, manufacturers add technologies such as liquid cooling or special high temperature materials. Both increase the cost and complexity and, in many cases, the size and weight of the machines.)
