Title: Structure of cooling member
Inventor: INOUE TAKAO
IPC: H05K1/05
Filed: 1994-07-06
Abstract: PURPOSE:To reduce the size and weight of heat radiating parts by employing those of graphite that is highly orientational. CONSTITUTION:When a power transistor 2 generates heat, some of the heat is transmitted to a sealing case through a heat conductive sheet. Heat is also transmitted to a heat radiating body 5 through a metal board and a heat conductive wiring 16. As a result, the power transistor 2, if heated, is efficiently cooled. No aluminum heat radiating part is used to transmit or radiate heat, which makes it possible to reduce the size and weight of the sealing case 1 and so on. Heat generated from a power transistor 3 is radiated in the air through a heat sink 20 and is transmitted to a heat radiation board through wiring pins. The transmitted heat is further transmitted to the heat radiating body 5 and is radiated through it. The heat sink 20 is made of graphite powder. This obtains thin radiating fins and enables efficient heat radiation. Therefore, the heat sink 20 is smaller and lighter than those of aluminum.
