Title:
放熱部材
Document Type and Number:
Japanese Patent JP7312515
Kind Code:
B2
Abstract:
This heat dissipating member (1) is provided with: a heat dissipating layer (20) having a polymer; and a protective layer (30) stacked on the heat dissipating layer (20). The heat dissipating layer (20) is arranged to be in contact with a counterpart member (9), and has a thermal conductivity of 0.3-3.0 W/mK in the stacking direction. The thermal resistance of the protective layer (30) calculated by equation (1) is 2.0x10-6 to 1.5 x10-2 m2K/W inclusive. (I): Thermal resistance of protective layer = L/k [L: thickness (m) of protective layer in stacking direction, k: thermal conductivity (W/mK) of protective layer in stacking direction]
