PURPOSE: To improve outgoing radiation, and to simplify assembly and decomposition by providing a radiation housing, having a holding pole and a pole-bearing recessed hole in a module-type electronic circuit package. CONSTITUTION: An assembly 1 is provided with a planar substrate 2 having a rectangular shape, and members 11 and 12 constituting a radiation housing 10. The members 11 and 12 house a device 6 and a circuit part 7 mounted on the substrate 2, and they are brought into direct contact with the device 6 and the circuit part 7, and heat is radiated by a cooling fin 28. When the members 11 and 12 are assembled, the substrate 2 is fixedly set at the corresponding positions of the members 11 and 12 by an opening 15. On the other hand, the members 11 and 12 are fit by a holding pole 13 of the member 11 and a pole bearing recessed hole 14 of the member 12, and the assembly can be achieved with a prescribed allowable by the fitting of the supporting pole 13 of the member 12 and the pole-bearing recessed hole 14 of the member 11. |
