What is a fan? And where can one buy one?

Question

Cooling systems

I dismantled the Kraftway Cedo kc14 workstation to clean it of dust and lubricate the fan. He removed the fan, cleaned it of dust, but it did not work to lubricate it, because it was not possible to open the "axial part" (as it is called) of the fan. Does it open at all? It is not clear, in general. The sticker on the fan says: model YD7515HS; YETU. I tried to find information about this fan on the Internet, I did not find anything. Please provide information about this fan. Can it be lubricated? Where to buy, order? Thanks in advance!
Information on the sticker in full: YETU; Model YD7515HS; DC 12V; 0.20A; 49-L1F18001; CE; http://lxhahu.cn.ali baba.com

"Impeller" in the hands, as a sample, but rather the whole computer, and in any normal workshop where laptops are repaired - they will pick up an analogue either from used ears from disassembly, or they will order a new one.
