Regarding air cooling
Thread Content
I have an idea: what if a metal plate is placed above the air cooler, with many holes made in that plate? Various components could be installed in those holes – something similar to a mineral water bottle from which the bottom has been removed; the larger end of such a component would be welded to the openings in the metal plate, while the smaller end would face the tubes of the air cooler. Would this approach help reduce temperature, and could it contribute to energy savings?
It probably won’t work! Unless the air flow rate and contact area are increased.
This involves increasing the air flow velocity
I don’t know what an “air-cooled” system looks like exactly, but I can roughly understand its meaning from the wording. Anything that increases the contact area between gas and liquid is beneficial for heat transfer. Literally speaking, is the cooling water evenly distributed across the sieve plates, and does the rising air pass over these sieve plates at that point? If that’s the case, some air-cooled towers are designed in this way. It’s not about whether it is or not; just for reference.
The surface scouring was increased, but it was uneven and it increased the load on the fan; the flow rate was still adjusted by changing the area of the narrow section and the ventilation volume.
Now, water-cooling chambers are placed under the air-cooling fans to lower the air temperature through circulating water
In industry, forced-air cooling is generally used; air flows from bottom to top through the tube bundle. It’s not effective at the upper end, but it works fine at the lower end. However, this increases air flow resistance and leads to energy losses in the fan, which is not worth it
There’s no need for that; with proper fin design and a variable-frequency motor, air cooling is sufficient
My question is whether it’s possible to save electricity and reduce energy consumption
