Experimental investigation and optimization of loop heat pipe performance with nanofluids

High heat generation from electronic devices needs to cool down properly to prevent overheating. Loop heat pipe (LHP) is one of the excellent cooling devices for high heat generation of electronic devices. Nanofluid is a working fluid which has nanoparticle dispersed in based fluid. Nanofluid is pro...
