| 摘要 | PURPOSE:To contrive an improvement in thermal shock properties, by specifying a porosity of a ceramic radiator. CONSTITUTION:A porosity is made into 50-90%, in a ceramic radiator wherein a large number of pieces of linear extruded stock made of ceramic is wound and laminated spirally respectively and spiral wound laminates are molded in a state either joined or twined round with each other at adjoining faces respectively. As for a material of the ceramic radiator, eucryptite (Li2O, Al2O2, 2SiO2) and spodumene (Li2O, Al2O3, 4SiO2) which are lithium low thermal expansion material can be used beside augitite. In addition to the above, as for distinctive features of a radiating plate, as structure of the same having predetermined frame size is strong against thermal shock, when the same is used for a part wherein a temperature exceeds a heat-resisting level of the low thermal expansion material, materials such as mullite (3Al2O3, 2SiO2), alumina (Al2O3) and magnesia (MgO), whose heat resisting properties are high while a thermal expansion ratio is large are selected appropriately. | ||||||
