PROBLEM TO BE SOLVED: To provide a cooling system which can selectively and efficiently cool a plurality of heating elements and has a high degree of freedom in layout within the system. SOLUTION: An exhaust heating element 5 having a large heating capacity is arranged behind a frame 3. By heating the exhaust heating element 5, an ascending air current 12 is generated to turn the inside of the frame 3 into negative pressure. Using this negative pressure, an intake air 14 taken in from intake air holes 2 of the frame 3 is selectively blown against heating elements 4 inside the frame 3 to cool the elements 4.
