Abstract

PURPOSE: To produce cooling fins for self-cooling with excellent efficiency, by adopting the pitches of grids ensuring the lowest thermal resistance decided by the hardness or ease of the flowing of the air of grid fins and the area of heat transmission.
CONSTITUTION: Auxiliary fins 3 formed by continuously bending sheets of aluminum or copper are inserted among a pluraliry of flat fins 2 provided by mounting 2 in parallel on a base 1, and fixed by means of brazing, etc. A semiconductor element 4 is installed to the base 1. When the pitches of grids are made to be 10W 12mm, efficiency can extremely be bettered. Thus, heat generated by means of the semiconductor element 4 is transmitted to the fins 2 and the auxiliary fins 3 from the base 1, and this device can efficiently be cooled by the streams of air by natural convection. The auxiliary fins can also be formed in truss-like or wavy shapes. U-shaped fins or wavelike fins can also be used in place of the flat fins 2.
