Cool Technologies Granted New Patent for Radial Vent Cooling


On February 24, 2017, Cool Technologies, Inc., an innovator in mobile power generation, energy efficiency, and heat removal technologies received the US patent (9,543,809) 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,” said Tim Hassett, Cool Technologies’ CEO and a 30-year veteran of the motor and generator industry. “In an industry which relies on incremental modifications to improve its products, real innovation is big news.”

 

The radial vent technology cools and increases the power density of rotating equipment such as motors, and generators.  By rapidly transferring heat from core of the electric motor to vents where it is expelled, the patent should 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.

 

Radial vent technology provides the same benefits for less than anything else on the market.  The technology is passive – no additional power is required or diverted for it to work.  As a result, generators are smaller, simpler, lighter and less costly.    

 

Radial vents will be incorporated into the generators that underlie the company’s Mobile Generation system. Not only will they be more powerful and economical than the competition, but the smaller package should enable them to be incorporated in a wider range of vehicle makes and manufacturers than the Ford trucks that have been retrofitted so far.

 

“The MG system is just the starting point.  The patent can impact almost any electrical machine up to 10,000 horsepower or more,” added Mr. Hassett.  “The larger the machine, the greater the heating problems. Fortune 500 companies have teams of engineers dedicated to address this single issue.“

 

The potential applications encompass process manufacturing; heating, ventilation and air conditioning (HVAC); refrigeration and air conditioning (RAC); electric vehicles and hybrid electric vehicles; vehicle components; turbo chargers;  exhaust gas recirculation (EGR) coolers; turbines;  marine and jet engines to name just a few.

 

The company is currently seeking partners to spearhead the implementation of the technology in a growing electric motor market that’s currently estimated to be worth $125 billion. Full rollout could involve dozens of licenses and generate revenues for decades to come.
