ABSTRACT:
A radiating device 10 has a rectangular parallelepiped block 11. Block 11 includes a first group of holes 12 to 19 and a second group of holes 20 to 23 causing convection of air. Passages for circulating gas and liquid serving as a heat pipe, are formed to extend in X, Y and Z directions in block 11. Opening ends of respective passages are closed by pins 51. The air heated in the holes is discharged to the atmosphere from the top surface of the block through the second group of holes. Accordingly, cool air in the atmosphere absorbed in the holes of the first group, carries the heat generated from the inner wall surface of the holes, is discharged to the atmosphere from the top surface of the block. Working fluid sealed in the passage frequently repeats an evaporation and condensation. The liquid condensed at the radiating portion returns to the heated portion along an inner wall surface defining the passage.
