"24V DC Cooling Fan" system uses forced air cooling mode, select the appropriate cooling fan system directly determines the thermal conditions. To fan selection, you first need to determine the amount of cooling air system needs to calculate the following formula:? Where T represents the system inlet / outlet temperature difference. "24V DC Cooling Fan" selection system to combine air traffic demand, the system resistance, fan characteristic curve requires a comprehensive assessment to confirm. Forced air duct system is actually very critical, "24V DC Cooling Fan" air duct and ventilation is generally divided into two ways, these two methods are the advantages and disadvantages
