A passive vehicle cabin insulation method with constant temperature and ultra-low energy consumption. It accomplishes this through the implementation of several special features in different parts of the vehicle. These features include a layer of efficient heat insulation material, an airtight casing, windows insulated with multiple layers of vacuum, energy-saving, laminated glass, an anti-UV heat insulation coating, an efficient fresh air circulation and heat recovery system, a broken bridge structural design, and an anti-fog and hazy air purification system. The method insulates the vehicle sufficiently to deal with the heat of summer and the cold of winter. It also makes full use of passive renewable energy, and maintains a healthy and comfortable driving environment within the vehicle. Specifically, it maintains a constant temperature, constant humidity, constant oxygen levels, constant levels of air purity, and low noise, all while consuming a minimal amount of energy.

The invention provides a heat shield for a heat- and sound-radiating component in a vehicle. The heat shield includes a carrier which has an inner side which, in the mounted state, faces the component and on which a continuous insulating material is arranged, for the absorption of heat and sound which are produced by the component. The carrier has a plurality of apertures in order to reduce sound radiation of the carrier. The provided embodiment and arrangement of the apertures, and the arrangement of the insulating material on the inner side significantly improve the sound- and heat-insulating properties of the heat shield.

The invention provides processes for making a coaxial device by simultaneously extruding a polymer encapsulation layer defining a hollowed area and filling the hollowed area with PCM composition in liquid form. The invention is useful for thermal management in a variety of applications in such as, for example, automotive, building, packaging, garments, and footwear.

The invention relates to an acoustic sheild having a thermo-compressed shell based on fibres bound together by a thermoplastic binder to form a porous shell that has noise absorption properties. The shell has an internal face and an external face, and a sheet of metal for thermal protection against the engine. The sheet covers all or part of the internal face, the sheet is attached in a substantially fluidtight manner, essentially via its periphery to the shell. This creates a peripheral seal and maintains, except at the periphery, an air gap between the sheet and the shell, to protect the shell from the heat accumulated by the sheet.

An exhaust assembly for a vehicle. The exhaust assembly includes a header assembly including one or more head pipes, and a bridge with a first end and a second end that is opposite the first end. The first and second ends are secured to the header assembly. The exhaust assembly further includes a shield assembly including a shield shaped to cover a portion of the header assembly and a retainer secured to the shield and supported by the bridge by a planar clamp joint therebetween.

The working vehicle includes an engine installed in a front portion of a traveling machine body, and a post-processing device configured to purify exhaust gas from the engine. The post-processing device is mounted on an upper side of the engine. The engine and the post-processing device are covered with a hood. A hood shield plate is disposed on a rear surface side of the hood and covers at least the post-processing device from a rear surface. A heat insulating layer is formed between an operating seat disposed on a rear side of the hood and the hood shield plate.

An exhaust manifold cover is provided with a plate-shaped cover member for covering at least a part of a heat source. The cover member has a first affixation section and a second affixation section, which are affixed so as to be in contact with the heat source. A bellows section in which ridges and grooves extending in a transverse direction perpendicular to a centerline passing through the first and second affixation sections are alternately formed is provided on the cover member at a position between the first and second affixation sections. The bellows section has formed therein a groove pair composed of two grooves having different widths of the two grooves composing the groove pair, the first groove which is near the first affixation section has a greater width than the second groove which is near the second affixation section.

A heat shield has a first layer, a second layer and a third layer. The first layer may have an outer surface and an inner surface. The second layer may have a first inner surface and a second inner surface. The third layer may have an inner surface and an outer surface, where the outer surface is defined by a plurality of dimples.

The present invention aims to provide a sound-absorbing material having sound absorption performance with an average sound absorption coefficient of 0.65 or more in the frequency domain of 800 to 2000 Hz. The present invention relates to a sound-absorbing material including: a fiber layer including a plurality of holes open to a surface thereof and having a thickness of 3 mm or more; and an inorganic material layer formed on the surface of the fiber layer, the holes being blind holes each penetrating through the inorganic material layer and having a bottom inside the fiber layer.

A high heat polymer with improved sound deadening properties is provided. The material includes recycled PET (Polyethylene terephthalate) as its base polymer and combination of mineral fillers and fibers to improve heat deflection temperatures and to create a barrier within the polymer that blocks noise. The material uses use a combination of basalt fibers and mica to provide improved resistance to heat and improved elastic modulus and significant dampening of sound. The high heat performance and improved sound attenuation of the material enables the deletion of heat shields and added NVH pads to many under body and under-hood parts, as well as significantly reducing the material cost and weight in automobiles.
