The OnePlus 11 Concept phone includes PC-like liquid cooling
 

After a wave of teasers, OnePlus has revealed its latest experimental phone — and this time the features are more practical than in the past. The OnePlus 11 Concept centers on "Active CryoFlux" liquid cooling that mimics what you see in some gaming PCs. The system uses a piezoelectric ceramic micropump to send cooling fluid throughout pipelines in the phone (visible on the outside) without "significantly" increasing the phone's bulk.
