The air cooler is a device that uses ambient air as the cooling medium and sweeps the outside of the finned tube to cool or condense the high-temperature process fluid in the tube. It is referred to as "air cooler" or "air-cooled heat exchanger". Air coolers can be divided into induced draft air coolers and forced draft air air coolers.
The advantages of induced draft fans are:
- The air flow is evenly distributed;
- Less noise;
- The space under the tube bundle can be used.
The disadvantages of induced draft fans are:
- The fan is installed on the upper part of the tube bundle, which is affected by the high temperature of the tube bundle, which is not conducive to maintaining the fan;
- The temperature of the air entering the fan after passing through the tube bundle is higher, so the power consumption of the induced air type is about 10% larger than that of theforcedtype fan;
- The tube bundle needs to be repaired from the bottom, which is inconvenient to operate.
What are the advantages and disadvantages of forced draft fans:
The advantages forced draft fans are:
- It is easy to produce turbulence, which is beneficial to heat transfer;
- Lower operating costs.
- The tube bundle can be checked and repaired from the upper part, and the operation is convenient.
The disadvantages are:
- The air distribution is uneven;
2 The upper part of the tube bundle is open and easy to be affected by sunlight and rain.
