Abstract
A cooling unit has a vessel that is filled with a refrigerant. The vessel includes a heat receiving portion for receiving heat from a heat generating component, a heat dissipating portion for dissipating the heat from the heat generating component, and a heat transfer portion for transferring the heat transmitted to the heat receiving portion to the heat dissipating portion via a refrigerant. At least the heat receiving portion of the vessel is formed of a soft heat conduction sheet that receives the heat from the heat generating component. The heat conduction sheet is directly in contact with the heat generating component.
