Patent ID: 8708556

Claim:
A thermal analyzer that heats and cools a sample placed inside a furnace for measuring a thermal characteristic of the sample during heating and cooling, the thermal analyzer comprising: a multilayer structure for covering the furnace and its surroundings so as to isolate the furnace and its surroundings from an external environment, the multilayer structure including a multilayer wall comprised of two layers formed of a material having high thermal conductivity and heat dissipation property, the two layers being spaced apart from, and not in direct contact with, one another to provide therebetween an interlayer space that contains a substance having a heat capacity substantially equal to a gas contained in the furnace so that heat transfer between the two layers is minimized; and a cooling block configured to be connected to a cooling device for cooling the furnace, the cooling block being arranged below the furnace through intermediation of a heat resistant material and having a heat insulation material covering the cooling block and its surrounding so as to insulate the cooling block from heat of the external environment.
