According to the relevant formula,<a href="http://www.monclerparis.org" target="_blank" class="postlink">moncler paris</a>, matching parameters are calculated, see Table 2. Table 2 match the parameters of the radiator fan and D / mmn ~ / (r · min) Qs / (ms) p / (m3.S) △ / kPa35047005.759.60.4 specific matching process is as follows: 1) determine the fan and cooling The match point R point (and △ by the values in the matching diagram can be determined.) 2) from the fan database, find the fan diameter D, a variety of fan speed is less than one curve, and the fan performance curve has a response curve through the R point. 3) to determine the matching fan and cooling system, points S points. Obtained by screening 3 to meet the requirements of the fan performance curve. As shown in Figure 5 to 7. It can be seen from Figure 5, A-type match point with the system fan speed is 2300r · rain ~, is less than n ~. 2300r · min corresponding to the power of 0.21kW, efficiency of 40%. It can be seen from Figure 6,<a href="http://www.uggsbotas.com" target="_blank" class="postlink">ugg botas</a>, B-match point with the system fan speed is 3000r · min ~,<a href="http://www.eccoshoesoutlet.net" target="_blank" class="postlink">ecco shoes outlet</a>, than any one. 3000r · min corresponding to the power of O_3kW, efficiency is 25%. It can be seen from Figure 7, C-type matching points with the system fan speed is 3500r · min ~, n is less than one. 3500r · min corresponding to the power of 0.2kW,<a href="http://www.ugg-pascher.org" target="_blank" class="postlink">ugg pas cher</a>, efficiency of 30%. 4) compared. Results show that the lowest noise and efficiency, corresponding to the highest point,<a href="http://www.toryburchshoes-outlets.com" target="_blank" class="postlink">tory burch outlet</a>, usually the highest efficiency as the optimal scheme. B-type fan efficiency of matching points lower than the A-type fans, and power consumption is large; C-type matches the speed of the fan is too high, noisy; and A-type fan speed matching points 2300r · min ~, rated power of 0.21kW, efficient 40%; So, ultimately determine the selection of A-type fan, the structural parameters shown in Table 3.
