Abstract: The invention relates to a cooling system and an electronic apparatus using the same, and particularly aims to use a thermosiphon as the cooling system and derives an optimum shape (inter-fin gap, fin height, and fin upper-end hole diameter) of a boiling heat transfer surface for different coolants. In a cooling system using a thermosiphon according to the invention, an optimum shape (inter-fin gap, fin height, and fin upper-end hole diameter) of a boiling heat transfer surface of a heat receiving jacket that forms the cooling system is identified based on a critical radius of a steam bubble produced in an overheated liquid and the diameter of an air bubble departing from the heat transfer surface for a variety of coolants.
