Abstract
Embodiments include thermal covers to help drain fluids away from dangerous environments, e.g., in an engine bay in a vehicle. Thermal covers can comprise a hat portion extending between two distal edges, support straps beneath the hat portion and extending between the distal edges, and thermal insulation disposed between the hat portion and the support straps. These can be coupled to the floor so as to allow space below for the flow of fluid. This allows the fluid to flow to holes in the floor of the engine bay, allowing the fluid (which could be flammable) to be drained away from potentially dangerous environments in the engine bay which may involve high temperatures.
Claims19
A thermal cover for protecting one or more components in an engine bay, the thermal cover comprising:
- one or more hat portions configured to extend across one or more components on a surface in an engine bay and configured to be coupled to the surface along first and second distal edges;
- one or more support straps configured to extend across the one or more components and between the first and second distal edges, the one or more support straps configured to sit between the one or more hat portions and the surface and to be spaced apart from the surface forming a fluid drainage gap;
- one or more thermal insulation sheets configured to fit between the one or more support straps and the one or more hat portions;
- and
- one or more coupling assemblies comprising a threaded bolt extending through a hole in a hat portion of the one or more hat portions and a spacer configured to maintain a clearance between the hat portion and the surface, thereby preserving the fluid drainage gap, and the surface and to receive the threaded bolt, the one or more coupling assemblies configured to couple the one or more hat portions to the surface along the first and second distal edges, the one or more coupling assemblies configured to allow fluid flow along the surface under the thermal cover.
A thermal cover for protecting one or more components in an engine bay, comprising:
- a hat portion configured to extend across a seam in a floor of the engine bay;
- a plurality of support straps disposed beneath the hat portion and suspended above the floor to define a fluid drainage gap wherein the one or more support straps are arranged in a ladder configuration beneath the thermal insulation sheets;
- a thermal insulation sheet disposed between the hat portion and the plurality of support straps;
- and a coupling assembly comprising a threaded bolt and a spacer configured to secure the hat portion to the floor while maintaining the fluid drainage gap.
