Abstract
A thermal analyzer heats and cools a sample placed inside a furnace for measuring a thermal characteristic of the sample during heating and cooling. The thermal analyzer has 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 includes a multilayer wall with two layers formed of a material having high thermal conductivity and heat dissipation property. The two layers are spaced apart from one another to provide therebetween an interlayer 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.

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.
A thermal analyzer comprising:
- a furnace configured to receive therein a sample that is to be heated and cooled for measuring a thermal characteristic of the sample;
- a heat insulation structure covering the furnace so as to isolate the furnace from variations in temperature external to the thermal analyzer, the heat insulation structure having a multilayer wall formed of a plurality of wall layers including two wall layers spaced apart from, and not in direct contact with, one another to form a space between the two wall layers, and a gas layer formed in the space between the two wall layers and having a heat capacity substantially equal to a gas contained in the furnace so that heat transfer between the two wall layers is minimized;
- 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
- a heat insulation material covering the cooling block and its surrounding so as to insulate the cooling block from heat of the external environment.
