*2.2. Liquid Cooling*

The liquid cooling methods show promising performances thanks to the high thermal conductivity of refrigerant fluids. Indeed, the high weight (including the liquid coolant and the sealing elements to avoid the fluid leakage) and the high manufacturing costs for the fluid coolant circulation system represent some penalties [16], but when high cooling performances are required, air cooling is not sufficient. Here, two leading liquid cooling technologies are presented: cooling plates and heat pipes.
