Not the same as Stirling engines

I dont understand why every one is confusing stirling cryocoolers with stirling engines. Applications of both the sytems are poles apart. Stirling cryocoolers should be linked to stirling cryocoolers and not to stirling engines. Don 04:47, 15 November 2005 (UTC)[reply]

Really terribly written article

I'm not an expert on the subject, but skimming this article I saw several lines that look really bad.

"The Joule-Thomson (JT) cooler was invented by Carl von Linde and William Hampson so it is also called the Linde-Hampson cooler." - then why is it also called a Joule-Thomson cooler? That would be nice to know. Is there someone named Thomson involved in the invention that is getting snubbed by von Linde and Hampson?

"The thermodynamic and hydrodynamic properties of regenerators are very complicated, so one usually makes simplifying models." - not sure what information this is supposed to convey to readers of an encyclopedia article except maybe that the author is asking to be excused for not explaining things clearly?

"The recent progress in the cryocooler field is for a great deal due to the development of new materials with a high heat capacity below 10K" - 10K what? 10 degrees kelvin? 10,000 something? Not only ungrammatical, it doesn't really say anything. -> 10K = 10 Kelvin, it does not need degrees, and if you write Kelvin it should be capitalised as it is a unit named after a person.

" Basically (cheap) compressors of domestic refrigerators can be used, but one must prevent overheating of the compressor as it is not designed for helium." - this is a good example of a line that looks like it was translated from sales literature.

If someone who speaks English fluently and knows anything about cryocoolers could review this article and clean it up, that would be great. It looks like it has a lot of extraneous information and that a lot of the article appears to be written by someone who didn't really understand the material they were translating. 162.232.246.7 (talk) 04:25, 12 November 2014 (UTC)[reply]

Etymology of the easily annoyed

It would be delightful to read a brief passage like: The name 'cryocooler' is admittedly an unfortunate one for anyone who appreciates etymological precision and is so petty that they wince every-time they hear "hot-water heater". Since 'cryocooler' is a rude splice of "cryo-" from the Latin meaning "very cold, freezing," from Latinized form of Greek kryo-, comb. form of kryos "icy cold"" and the Norse/Germanic "kuhl" for "to be cold", it is understood that 'cryocooler' is a 'cold colder'.

Intro

This article needs a better introduction. "A Cryocooler is a standalone cooler, usually of table-top size" does not give nearly enough basic information to even identify the topic from the many other types of refrigerators that exist. Jess_Riedel (talk) 18:17, 18 January 2019 (UTC)[reply]

Why only oscillatory flows

Why is this article assuming and discussing only those "operating with oscillatory flows," rather than circulating flows ? Is this article actually just about Stirling cryocoolers ? or oscillating-flow cryocoolers ? If there are no other types, can we say why ? - Rod57 (talk) 16:36, 19 December 2020 (UTC)[reply]
