This is such a good video. I need to have this replaced and I was having trouble understanding exactly how it works. Most videos show a convoluted diagram without detailing EXACTLY how the water flows, heat is exchanged etc. You guys are master teachers - not just explaining the concept, but anticipating the questions that someone completely new to the topic would have. Thank you.

Great video thank you so much. Can i please ask how does the cold medium flows upward? I dont understand why it doesn't just stay on its horizontal flow? What pushes it to move up? it can't be only because of the plate's shape. Should i assume that the hot medium flows downwards because of gravity? Please help me please

what is the disadvantage of plate lubeoil cooler compared to tube type cooler?
A. Locating cooling leaks is more difficult
B. Smaller and lighter
C. Additional plates can be added in pairs to increase capacity
D. Higher efficiency
Please sir answer this.

Sir, I have one question, is it possible that the available friction factor and heat transfer coefficient equations for plate type heat exchangers can be used for plate and fin type heat exchanger? Specially for two phase flow. with condensation vaporization

I have question regarding the connection: if we connect the secondary circuit pipe on the cold side and and the primary ( District cooling ) on the hot side, dose this reduce the heat transfere between them? ( secondary circuit 5 c more than design )

Nice video! Really enjoyed it, made it entirely clear how it works. Just one unimportant thing, the plate exchanger in the end of your vid seems to be from Norwergian/Danish actually judging by the language: )
Thanks again

I have one question, why is the valve being installed between the cold water coming in and out of the exchangers, I often see the valve completely open on the exchangers?
With this valve the exchanger loses its purpose.

I didn't realize I liked engineering topics until I came here, after beginning to learn how to warm a vermiculture bin using the heat from a hot compost bin. This is fascinating. I understand now! Thank you!

you know what you are talking about. but explain to someone who doesn't know what thing thing does. You are too Engineering. be more What is a Heat Exchanger. Why talk about bolts?

That was a great explanation, I was thinking to use something like that to use the wasted exhaust heat from a diesel parking heater to heat up water for a camp shower if possible.

Seriously I watched a lot of videos about Plate HX trying to understand how exactly this works and I've never been able to understand it, untill this video. Thanks so much

Very good explanation, but if the plates are spherical (not rectangular) with the same area. has the same efficiency? or the length of plates determine the efficiency?

Wow! I never managed to understand or imagine how these exchangers worked until your video came to the rescue. This is the best explanation handout. Thank you so much.

would you advise variable temperature of heat exchanger or does constant temperature fluctuation is bad for the heat exchanger?

As a Danish I can confirm that it is infact a Danish heatexchanger and not a German one.
But great video, learned alot

Can it work for the liquid high vecosity 30000 cp, high temp 95 C? I want to cool down this liquid by cooling water 30C

Very well done. Interesting how the concept is simple, but the manufacturer of the instrument is complex.
