China Wholesale Temperature sensor Factory – LEAT-4 Thermal Conductivity Measurement Apparatus – Labor Detail:
The experimental methods for measuring thermal conductivity are generally divided into steady-state method and dynamic method. In the steady-state method, the heat source is used to heat the sample first, and the temperature difference inside the sample makes the heat transfer from high temperature to low temperature, and the temperature of each point inside the sample will change with the heating speed and heat transfer speed; when the experimental conditions and parameters are properly controlled to make the heating and heat transfer process reach the equilibrium state, a stable temperature distribution can be formed inside the sample The thermal conductivity can be calculated from the temperature distribution. In this experiment, the steady-state method is used to measure the thermal conductivity of bad conductor (rubber sample), and the experimental method of calculating the conduction rate from the object heat dissipation rate is learned.
1. Measure thermal conductivity of poor conductor (rubber and bakelite samples included)
2. Learn how to calculate heat conduction rate using cooling rate
3. Learn how to use an integrated temperature sensor
