The Air-cooled heat exchanger is a device for rejecting heat from a fluid or gas directly to ambient air. When cooling both fluids and gases, there are two sources readily available, with a relatively low cost, to transfer heat to..air and water.
Air Cooled Heat Exchangers (ACHE) Plant operators today face the pressures of increased productivity goals and ambitious profit targets that contrast todays reality of rising energy costs, swelling operational expenses and diminishing operating budgets. Moreover, plant conditions can change very quickly, for instance, due to sudden increases
Air-cooled heat exchangers INDIVIDUAL SOLUTIONSThe economic profitability of an air-cooled heat exchanger depends on the capacity of the finned tubes. The capacity results from the transfer of the maximum heat exchanged in the smallest possible space while keeping thermodynamic losses on the air side low.
The hot medium (e.g. hot water or lube oil) flows through the heat exchanger within the large number of externally finned tubes. One or more fans force air across the tubes and the heat from the hot medium is transferred to the air. To maximize heat transfer, the tubes are equipped with fins that increase the area in contact with the air.
Cooling high-horsepower motors with heat exchangersDec 15, 2001 · With air-to-air cooling, a blower on top of the heat exchanger pulls air through a filter at the bottom of the heat exchanger, then across cooling tubes. The recirculating motor air passes through and is cooled in these tubes. The second option is air-to-water cooling. Here, the recirculating airflow passes over the outside of cooling tubes.

Air cooled heat exchangers design good practicesMay 22, 2019 · Operating Costs:Power requirements for air-cooled heat exchangers can be lower than at the summer design condition provided that an adequate means of air-flow control is used. The annual power requirement for an exchanger is a function of the means of air- flow control, the exchanger service, the air-temperature rise, and the approach temperature.
TheBasicsof AIR-COOLEDHEATEXCHANGERSAn ACHE is a device for rejecting heat from a fluid directly to ambient air.This is in contrast to rejecting heat to water and then rejecting it to air, as with a shell and tube heat exchanger and a wet cooling tower system. The obvious advantage of an ACHE is that it does not require water, which means that plants requiring large
