Are there any air-cooled versions? What is a suitable wind speed on the windward side?
Thread Content
I designed a small air cooler with a very small temperature difference on the hot side. If finned tubes are used, the area exposed to the airflow is small, and if the air flow velocity is low, the temperature rise becomes quite high. How much is generally appropriate?
Also, are there strict regulations regarding the number of pieces per meter in length?
I think it was mentioned in some materials; I can’t remember. . .
The number of fins per meter is specified as a parameter for air-cooler types (corresponding to the fin ratio), while the wind speed facing the cooler is generally around 2.5 meters per second (depending on the number of tube rows).
The wind speed is around 3 m/s. There are regulations regarding the spacing between the fins; I’m not sure what type of fins you use
On the software, there are typically 433 fins per meter. For 4-row ducts, the wind speed is generally around 3.3 meters per second, while for 6-row ducts it is around 2.7 meters per second; based on this, the wind pressure of the fan to be used should be determined.
