But because there is no convectional cooling in the vacuum of space, the heat generated by electricity passing through the circuits can build up in circuit boards, eventually destroying them. The Chung-Shan Institute of Science and Technology had long been interested in the problem of how to dissipate heat in a vacuum, but lacked access to space research.
但太空環境無法散熱，導電產生的熱氣累積在電路板上，將燒掉儀器，缺乏「太空經驗」的中山科學院就很有興趣一探「真空中如何傳熱？」
