Calculations for Convection Cooling

Kalkulating converection heat transfer involves te convective heat transfer coefisien (h), wwhich dependh on airflow conditions. Te basic formula is:

1f 1f; 1f; FLT: 0 123; Q = h × A ADE OLT 1; FLT: 1 123; 1st; 1f 3;

Dimana:

  • 1f 1f; 1f; FLT: 0 = 33. Q = 1; FLT: 1 1f 3; = heat transfer rate (W)
  • Pertama; FLT: 0 = 0 = 33; h = 1f; FLT: 1 123; Aver3; = convotyva transfer coefisien (W / m ²)
  • 1f 1f; 1f; FLT: 0 133; Abo3; A 1; FLT: 1 Aver3; = surface area (m ²)
  • Pertama; FLT: 0; AF3; AFT CONT1; FLT: 1 ASA3; = temperatur diferenque between surface anr (K)
