    Calculation of water flow rate in heat exchanger

    Thanks BvU & Chestermiller. I have to pick ready-made HE. (a) I have attached the datasheets for off-the-shelf HE model WL500 from Laird technologies. One of them contains dT vs cooling capacity graph. Since I want to lift 250 watts, corresponding dT = 8 deg C. So if ambient temp. is 22 C...

    Calculation of water flow rate in heat exchanger

    (1) This is related to CCD cooling; ambient temperature range is from -5 deg C to 22 deg C over a span of a year in my case. This is optical telescope application. During night observations of sky, temperature range is as mentioned above. (2) From my first post, from first eqn, I will find...

    Calculation of water flow rate in heat exchanger

    I am not a mechanical engineer; but I have physics background. I want to lift about 250 watts of heat from a metal block. At the same time I have to maintain its temperature at 30 deg Cel. For this I want to use water-air heat exchanger (HE). Heat exchanger will have inlet & outlet pipes. Hot...
