HEAT SHIELD FOR TEMPERATURE-SENSITIVE COMPONENTS

摘要

The present invention relates to a heat shield surrounding a part for a, temperature-sensitive part, a cover (7) made of intumescent material. The cover 7 is surrounded by a cladding (8) made of a metallic sheet, the cladding comprises a plurality of through-openings (8a) for the intumescent material swelling under heat action on their surroundings. When the intumescent material bulge out the intumescent material is pushed to the outside through the through-opening (8a), to form a heat-insulating shell to the peripheral part to be protected. ;
