  • Publication number: 20200072509
    Abstract: A device comprises an element bed providing a plurality of unit channels each containing an NICE element. The heat transport device has a channel switching mechanism and a biasing mechanism. The channel switching mechanism forms an inlet valve for allowing the heat transport medium to flow into the unit channel and an outlet valve for allowing the heat transport medium to flow out of the unit channel. The biasing mechanism applies different biasing forces to the inlet valve and the outlet valve. The magnitude relationship of the biasing force is the same as the magnitude relationship between the pressure of the heat transport medium acting on the inlet valve and the pressure of the heat transport medium acting on the outlet valve.
