Forced air cooling

Also note that capacitor manufacturers typically do not guarantee life under forced air cooling. The designer should either measure the capacitor without forced air cooling if possible, or add some judicious safety margin.

Linear heating ramp to 120 °C (3 min), temperature control using the feedback from the reference vessel temperature measurement (constant 120 °C, 20 min), and forced air cooling (20 min). The reaction was performed in eight quartz vessels...

Kleiner et al. [23] theoretically and experimentally investigated forced air-cooling, which employs microchannel parallel plate fin heat sinks and tubes. Optimization was performed and design trade-off was studied. Tube sizes were observed to have a significant impact on optimum heat sink design. Air-cooled heat sinks are used for micro channel heat sinks with heat loads less than 100 W/cm. ... 

The manufacturer generally recommends the maximum Pi, value higher-powered types may need to be forced air-cooled. 

Equipment Maintenance. Although users of forced-air cooling towers avoid some of the service problems common for atmospheric cooling towers, maintenance of fans, motors and water inlet nozzles is still necessary. A once-through system eliminates these costs but also increases the load on the water intake screening equipment. Water pump maintenance should be equal for both systems. 

In the above simple example some of the margin between 60 kA and 80 kA will be taken up by the sub-transient contributions from the motors. It can be noted at this point that if the transformer is subsequently increased in rating by the addition of forced air fans, then the fault current passed by the transformer will be unchanged. It is advisable to specify the rating of the transformer in its forced air-cooled mode of operation, if such cooling is considered likely to be needed in the future. This would ensure that the incoming circuit breakers and busbar normal rated currents would be correctly matched to the transformers. 

A device required for starting and stopping forced air-cooling fans. 

The main conclusion from this study is that the waste heat can be transferred from the stack up to a full load of 8-10 W under forced air cooling conditions without exceeding 80 C maximum MEA temperature. One individual microfan can be used for both fuel cell cathode air supply and stack cooling. Table 8-6 compares both models in terms of overall performance. Since the fan consumes energy, the system efficiency reduces...

For normalising, a soaking of the castings above the critical temperature followed by air cooling is necessary. Again a soaking temperature of 900 - 925 C is usually used, to ensure that the carbides are broken down. Forced air cooling is used to form pearlite. The type of heat treatment furnace available and the size of the load determines the process cycle that is possible. It may be necessary to adjust the metal composition with tin or copper to help the formation of fully pearlitic structures.

The I Li-ion battery uses an active forced air cooling system bringing chilled air in from the air-conditioner system. The thermal management system is also designed to actively cool the battery during charging in order to maintain the cell temperatures at optimal levels and extend the life of the battery. 

The associated equipment consists of a solid-state automatic voltage regulator that controls a thyristor converter which in turn supplies the generator field via a field circuit breaker, generator slip rings, and brush gear. The main power output from the generator to the step-up transformer is by means of a forced air-cooled, isolated phase bus duct, with tap offs to the unit service transformer, excitation transformer, and potential transformer cubicle.
