Abstract
Mini channel heat exchangers are largely used in several applications thus researchers are constantly working to find out the different ways to enhance the rate of heat transfer. Such activity is by no means completed. A simple product of nanotechnology nano-fluid, due to its extraordinary heat transfer performance it has become a topic of attractionMini-channel tubes are reasonable for little and light weight equipment's. Liquids are broadly utilized as warmth bearer along these lines to improve heat move rate warm conductivity of liquid ought to be expanded by certain methods, this can be best done by adding metallic particles to the liquid likewise called as nano-particles.Enhancement of cooling performance of mini-channel heat exchanger using titanium oxide nano-fluid is compared with water. The experiment is performed at different flow rates (24 LPH, 32 LPH, 40 LPH).
