Description

Soundproof heat dissipation material, equipment and members with soundproof heat dissipation material

The present invention relates to a soundproof and heat dissipating material, a device and a member with the soundproof and heat dissipating material.

In a mechanical device that has a noise source such as a compressor, it may be possible to reduce noise by arranging a soundproof member at the noise source as a noise countermeasure. Examples of the soundproofing member include a member including a urethane foam layer, an airgel layer, a cotton-like mixed long glass fiber, a fiber layer made of at least one of an organic long fiber and an inorganic long fiber.

However, since the soundproofing member has a heat insulating property, heat dissipation is hindered when the soundproofing member is arranged at the noise source. Here, as a soundproof member having excellent soundproofing properties and heat dissipation properties, a phenolic hard foam having an open cell structure is pressed and filled into cells of an aluminum honeycomb material to form a core layer material, and a sound is formed on one surface of the core layer material. A honeycomb panel body has been proposed in which a breathable surface material that allows heat to pass through is attached to another surface with a plate material that reflects sound but allows heat to pass through with an adhesive (see, for example, Patent Document 1).
