Abstract
A header tank for accommodating refrigerant is formed on one side of the cold plate, on the other side of which an electronic component is mounted. A plurality of loop pipes in which the refrigerant is circulated are connected with the header tank. The plurality of loop pipes are arranged substantially parallel with the cold plate. The radiating area of the loop pipes distant from the cold plate is larger than the radiating area of the loop pipes close to the cold plate.
