Abstract:
A circuit board packaging structure comprising:a plurality of circuit boards each packaged with electric circuit parts and disposed in parallel to each other, wherein a circuit board packaged with electric circuit parts exhibiting a larger exothermic quantity than those of the electric circuit parts packaged on other circuit boards of said plurality of circuit board is disposed outermost among said plurality of circuit boards and, at the same time, disposed so that the surface of the circuit board packed with the electric circuit parts exhibiting the larger exothermic quantity is directed outside; a first cooling fan for flowing cooling air from outside of the structure along said plurality of circuit boards to cool off the electric circuit parts packaged on said plurality of circuit boards; and a second cooling fan for pulling said cooling air in a direction from said first cooling fan along said circuit board toward the outside of the structure.
