For additional information: In liquid-to-liquid applications it is prefered to put the "dirty" water into the tube side since cleaning or plugging tubes is much easier than on the shell side. Some reasons to put multiple passes of the tubes include space as well as increasing fluid velocity for better heat transfer efficiency. In a recent application we put replacement chillers in with a 2 pass condenser rather than the current 1 pass to save on piping space on the other side of the room. Tubes can be "enhanced" internally and/or externally to increase heat transfer efficiency using fins or internal rifling.

Used to design the piping to these pieces of equipment as well as all equipment found on oil (etc) refineries / chemical plants etc... did so for decades. You bring back memories. When installed, there is a fixed end and floating end for these exchangers ... the floating end is the opposite end to the header and slides on its supports as it expands.
The piping needs to be designed with this and all stresses borne in mind.

This is very helpful and right on time, because I work with these heat exchangers right now! Many thanks.

Nice to see "shell and tube" type of heat nowdays! They have evolved over the years and a better understanding is achieved with this presentation particulary on the hydrodinamics of shellside flows. 👍

Nagledali smo se ovih i ovakvih izmjenijivača ....hvala.

I did water treatment on cooling towers 20+ years ago. I would’ve progressed into chillers & boilers more if I would’ve stayed with the on but my trainer was just to big an A-hole, I grew to despise him, & I feared becoming him. He made a lot of money but it doesn’t make up for being as big a tool as this guy was.

As a marine diesel mechanic, I'm very familiar with heat exchangers, since you can't place a radiator inside an engine room. Thank you for this lesson.

OMG 😱
Finally
I needed it!!!!
Thanks a lot

[daniellara]

Do some HVAC videos my guy. Thank you!!

[rickhicks]

I'm retired so no longer teach this type of information. But still enjoy seeing it.

The 6.9L and 7.3L IDI international Harvester Diesel engines used in Ford pickup trucks from 1983 to 1994 used these heat exchangers as oil coolers.

Here in the US the Double Pipe or Tube in Tube heat exchanger is also called a Plate and Frame heat exchanger.

Requesting topic. Air break system for a bus or truck transportation

Might be good for cheaper desalination as well. Pump filtered sea water into the header, heated to evaporation in the tubes, and back to the header with one outlet for heavier brine and one outlet for water vapor to be condensed and pumped out to the water supply. Seems way less expensive than reverse osmosis. Especially with 8 degree C temp difference between boiling points.

Instead of using straight Baffles use screw type Baffles to rotate the flow of water 360° to the heat exchanger tubes inside of the shell to increase the efficiency of heat exchanger

[purpleldv]

Is this the sistem that is used in regular combo (2 in 1) washer-dryer machines (not the ones with heat pumps) for condensation of the moisture drawn by the hot air from the clothes?
If so, does anyone know how exactly it uses the cooling water? Does the machine draw cold water continuously? Does it empty and refill the shell after every set amount of time? Or does it have a temperature sensor inside the shell that governs either the refilling of the shell or the debit of cooling water running through the shell?

[juanda]

I work in a coal power plant and this its also use after the vapor does the work in te turbine it goes to 5 of those to heat the feeding water

[DrArkham.]

This type of heat exchanger is also used in PWR type nuclear power plants.

At 4:00, the animation shows the milk being warmed starting from the outlet side and not the inlet side. Is there any reason for this, since warming it from the inlet side would be more efficient thermally? Love your videos BTW.
