Heat Exchanger Calculations

  1. Jan 19, 2015 #1
    Hello,
    I'm working with a heat exchanger I'm trying to integrate into a cooling application. I've done some tests but want to have some clear understating of how the calculations are done or if I have missed something. Below is what I have so far.
    So it's a radiation with 2 pwm fans, they push air through the radiator. It has a 1.7gpm water flow through the loop.

    Air temp into fans: 30.1C
    Air temp out fans (rear radiator): 59.2C
    Input water temp to radiator: 64.8C
    Output water temp from radiator:56.5C

    So what I get from this is that the radiator is removing 8.3C from the water temp. How would this translate to actual power or BTUs dissipated by the radiator?

    Power? You want BTU/hr if you're interested in English units. What's the definition of BTU?
