Title:
THERMAL CONDUCTIVITY MEASUREMENT DEVICE AND THERMAL CONDUCTIVITY MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/131482
Kind Code:
A1
Abstract:
This thermal conductivity measurement device comprises: a second clamping member which together with a first clamping member, clamps an object to be measured; a heating member which heats the first clamping member and has a contacting end surface which contacts a distal end surface of the first clamping member through a first axial correction member having two facing surfaces, and a distal end surface on the reverse side of the contacting end surface; a cooling member which cools the second clamping member and has a contacting end surface which contacts a distal end surface of the second clamping member through a second axial correction member having two facing surfaces, and a distal end surface on the reverse side of the contacting end surface; a plurality of temperature sensors disposed on the first clamping member and the second clamping member; and a pressing force applying mechanism which applies a pressing force between the heating member and the cooling member. At least one surface of the first axial correction member and the second axial correction member is a curved surface having a convex curved shape, and the other surface is a flat surface.
