You're not considering that the coolant is cooing down as it transits through the radiator tubes and gives up its energy. For both high and low coolant flow, let's assume the inlet temperature is the same and the ambient temperature is the same. . As the coolant flows through the radiator, the coolant will lose temperature as it transits though the radiator giving up its thermal energy. For the case with higher coolant flow, each increment of the coolant will have less opportunity to give up its energy since it is in the radiator for a shorter period of time, so the exit temperature for that increment will be higher than for the case with low coolant flow. That is compensated for because more "increments" will pass through the radiator per unit time than for the low flow case. Since the average delta-t between the coolant and the ambient air is greater (for coolant Tavg = Tinlet - Toutlet), the case with high flow will have greater heat energy transfer per unit time. |
