Title:
THERMOPHYSICAL PROPERTY PROBE
Document Type and Number:
WIPO Patent Application WO/2019/105357
Kind Code:
A1
Abstract:
Disclosed is a thermophysical property probe, comprising: a probe body formed by spirally winding a thermal wire (1) having an insulation film layer; a protection layer attached to an outer wall of the probe body; and two wiring terminals (6) connected to two outgoing wires of the probe body. The probe body comprises an elongated cylinder filament-shaped joint, an elongated cylinder needle-shaped joint, and a double helix disc-shaped joint, which test thermophysical property parameters of a substance respectively based on a transient thermal filament method, a transient thermal needle method, and a transient thermal surface method. The thermophysical property probe has a simple manufacturing process and low production costs. For the same-sized thermophysical property probe, the resistance of the probe can be increased several times to several tens of times, and the precision requirements for a collection device can be reduced. The thermophysical property probe has a precise structural arrangement and a high detection precision, effectively reduces the size of the probe, and reduces the quality requirements of the tested sample. The thermophysical property probe can realize integration of three typical structures of the filament, needle and double helix surface types into the same test device, can carry out the thermophysical property test on most substances, has strong versatility and practicality, and is easy to promote.
