What is the internal structure of a plug-type air cooler?
Thread Content
One main pipe goes in, where it splits into smaller pipes for heat dissipation, before coming together again as one main pipe to exit? Where is that plug again? Together with thin tube welding? Is it still a large fluid collection tank inside, with a plug connected to a hollow tube? I seek your advice
Yes, I know. I just don’t know whether one main pipe enters and then splits into several smaller pipes for heat dissipation, or how the heat is dissipated in that case. Are the pipes inside the plug hollow?
Looking at this diagram, it seems to be a four-stage system, with heat exchange in four stages
First, air coolers are largely similar to one another; there are many schematic diagrams available online that you can take a look at. Generally, the inlet is connected to a tube sheet, the outlet is connected to another tube sheet, and the two are usually linked by finned heat exchange tubes. Based on your description, the fluid collection box you mentioned is what is professionally referred to as a tube box. Put simply, it’s like drinking milk tea – two milk tea cups are connected by a straw! Second, let’s talk about the plug next. The position of the plug corresponds to that of the heat exchange tube. For maintenance. When the heat exchange tubes leak, it is necessary to unscrew the plug caps on the inlet and outlet tube boxes, insert the custom-made plugs into the heat exchange tubes – both ends need to be plugged to isolate the damaged tubes – and then reattach the plug caps. Ensure the proper operation of the air cooler!
There is space between the plug and the tube bundle
This is a finned tube; I’m not sure what the structure is like from the main pipe to these finned tubes
The feed material enters the square box and then goes straight into the finned tube
