High performance thermal link with small spring constant for cryogenic applications
نویسندگان
چکیده
We developed a soft and high thermal conductive heat link for cryogenic applications. The measured maximum conductivity was approximately 18500 W/m/K at 10 K. This spring constant 1/43 of that single thick wire with the same cross-sectional area room temperature. realized these performances by utilizing purity aluminum (99.9999 %, 6N) stranding many thin wires are 0.15 mm in diameter. electrical Residual Resistivity Ratio (RRR) also used to estimate Wiedemann-Franz law. observed size effect on conductivity, evaluated mechanical deformation RRR. These evaluations allow us design pragmatic application.

A small salt gradient solar pond with an average surface area of 1.8 m2 and depth of 0.8m has been tested. The depths of storage, gradient and surface zones are 0.3, 0.27 and 0.07m, respectively. The temperature of the storage zone for the summer days reaches its maximum of 65˚ C after about 8 days. Daily variation of the storage zone temperature was about 8˚C which is due to small volume of th...
