- •
Experiment was conducted to study the thermal performance of a helium PHP.
- •
A mechanical–thermal switch worked as a novel pre-cooling system was developed.
- •
For at +30° with 70.8%, the effective thermal conductivity was 4800–13,000 W/m K.
- •
Tests were performed with different heat power, tilt angle and LFR.
