Soundproof heat-dissipation cover, cover member, and manufacturing method of soundproof heat dissipation cover

Abstract

A soundproof heat-dissipation cover (3) that covers a target object (2), and includes a heat-dissipation contact surface (10) having a contact part (12) contacting the target object (2). The density is 0.1 g/cm3 to 2.0 g/cm3, the thermal conductivity is 0.1 W/m to 2.0 W/mK, and the maximum height roughness (Rz) of the heat-dissipation contact surface (10) is 50 μm to 300 μm. With an air layer formed between the surface of the target object (2) and the heat-dissipation contact surface (10) of the soundproof heat dissipation cover (3), the contact area between the surface of the target object (2) and the heat-dissipation contact surface (10) of the soundproof heat-dissipation cover (3) can be reduced, the vibration received by the soundproof heat-dissipation cover (3) from the surface of the target object (2) can be suppressed, and the secondary radiation sound from the soundproof heat-dissipation cover (3) can be suppressed.
