Title:
COOLING UNIT AND ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2017017199
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a small size cooling unit capable of performing a high cooling capacity and having a high degree of freedom in disposition, and to provide an electronic apparatus.SOLUTION: The cooling unit includes: an evaporator that vaporizes a part of a coolant by means of heat emitted from an electronic component; a condenser that cools the coolant; and a pump that circulates the coolant. The cooling unit includes a coolant circulation loop arranged to reduce the inner pressure, and the filling rate of the liquid coolant with respect to the capacity of the coolant circulation loop is set to 50% or more. With this, a high cooling performance is achieved cooling effect by an evaporation energy and cooling effect due to temperature raise by the liquid coolant.SELECTED DRAWING: Figure 2
