<p>PROBLEM TO BE SOLVED: To provide a cooling device capable of eliminating control of a cooling fan and a power source for circulating cooling medium, and of dealing with change in calorific value of electronic equipment.SOLUTION: Provided is a cooling device 3 circulating cooling medium 5 from a heat receiving part 6, an outgoing path pipe 8, a heat radiation part 7, a return path pipe 9, and again, the heat receiving part 6 to communicate heat. By forming a porous projection 16 on a heat receiving plate 11 receiving heat of a switching element 2, boiling of the cooling medium 5 is facilitated, and reduction in cooling capacity is prevented, and following to change in calorific value of the switching element 2 is possible.</p> |
