High-efficient rafled heat exchanger tubes and hydrophilic aluminium fins are adopted for the condenser, greatly improving the heat exchanger efficiency.
The above is a description about a high-efficient heat exchanger.
And the question is " Does this sentence have grammatical problem?", anyone who's kind to give an answer, thank you in advance.
Another question, can i change the latter part into ", which improves the heat exchanger efficiency greatly"?

Thanks for your so kind response, and i'm so sorry for my late comment and thanks.
Actually, i've been learning english for many years, and what so bad luck is, i still can't pick up this language well enough.
And i've been envying peopele like you having very good english, which is my ideal i've been longing for.
In fact, i still have many confusions in learing english, i.e i still don't know whether the expression of "systems theory" is right, or "system theory" is better. Can you kindly give me an answer?
Thank you again, wish you all the best.

It seems depending on context, both "systems theory" and "system theory" are correct.
For instance, when we say two weather storms may reinforce each other causing more wind and rains, it may be described as part of a discussion in "multiple weather" "systems theory".
While we can also say: "System theory" suggests that every system usually belongs to a higher-level system. (e.g. explaining what a system is)
I think "system theory" is taught in colleges for subjects in mathematics, engineering, social sciences etc. This is a preparation for learning the interactions between various systems which may be referred to as "systems theory" (I think so.).
Just a thought.
"It's how I see it, at least:)"
