Iranian Researcher Invents Isolated Air-to-Air Cooling Device in Industrial Electric Motors
For the first time in Iran, two special awards and a gold medal of the INTARG Competition in Poland were given to Massoud Arab Ameri, a student of the Islamic Azad University’s Shahroud branch and the inventor of the isolated air-to-air cooling device in industrial electric motors.
“In this invention, by simplifying the cooling path of high-power electric motors, air-to-air heat transfer has replaced the method of transferring air enclosed in the electric motor, and in this method, we used fewer electromechanical parts, which has reduced depreciation to a minimum,” Arab Ameri told ANA.
“Another remarkable and innovative point is the removal of fine dust and water vapor from the air circulating inside the electric motor, which has increased their lifespan several times and by preventing the oxidation of metal parts in contact with air and removing suspended dust, the need for repairs and maintenance has been reduced,” he added.
“This invention has a lot of industrial applications for areas with fine dust and it has been welcomed in the neighboring countries, specially in the Persian Gulf region, in various industries, including cement, flour and metal smelting plants,” Arab Ameri said.
An electric motor cooling system including an electric motor with an air coolant inlet and an air coolant outlet, a first housing extending over and affixed to the electric motor with an air flow passageway therein, a first blower secured to the first housing having an outlet connected to the air coolant inlet of the electric motor, a second housing affixed to the first housing with an air flow passageway therein, a second blower affixed within the second housing so as to force air through the air flow passageway of the second housing, and a heat pipe array affixed within the air flow passageways of the first and second housings such that the heat pipe array has a bottom half within the air flow passageway of the first housing and a top half located in the air flow passageway of the second housing. The first blower is a centrifugal blower.
