Measurement Apparatus and Method
The thermal performance for forced convection are measured as shown Figure 1, 2.
Figure 1: The Overall Experimental Setup
Figure 2: Duct Dimensions, Experimental Setup
- Airflow test chamber .The chamber, manufactured by Airflow Measurement
Systems, is designed in accordance with AMCA 210-85 standards.
- Please see each test condition for Heater Size
- A 1.4mm hole at the center of the test heat sink is made, and a thermocouple is
inserted to the heater. A small amount of thermal grease is applied evenly
between heater and heat sink base. Typically, data measurements are taken
multiple times.
