Research of Car Cooler Thermal Performance Depending on the Mileage of Cooler and Coolant

The effect of car cooler mileage and coolant on thermal performance was experimentally investigated. water–ethylene-glycol-based with mileages 0 km, 50,000 100,000 km circulated in new used coolers respectively. heating cooling time coolants, heat transfer rate, were evaluated. a the achieved 41 min 30 s, which is 8 less compared to cooler. When operating temperature reached earlier, engine ran more efficiently consumed fuel. 4 3 s shortest highest (η = 0.79). only one-time decrease coolant. for drop 1.01 1.02 times Coolant higher have no significant correct function engine.
