Superconducting nanowire single-photon detectors (SNSPDs) have become core devices in cutting-edge fields such as quantum communication, quantum computing, and deep-space laser communication. As typical cryogenic superconducting electronic devices, their key indicators such as detection efficiency and dark count rate, as well as the expansion of their application scenarios, are highly dependent on the cooling capacity, temperature stability, size, weight, and power consumption of the cooling system. This paper first briefly describes the detection principle, core performance indicators, and mainstream material systems of SNSPDs, clarifying the physical basis and technical requirements of their cooling needs. Then, following the logic of "evolution of application scenarios", it reviews the development from ground-based quantum applications to space-based deployment, and further to the breakthroughs in sub-1 K cooling technologies that support high-performance SNSPDs. Finally, in view of the integration and large-scale requirements of quantum technology, it looks forward to the future direction of small-size integrated cryocoolers and multi-channel cooling systems, providing a reference for the selection, optimization, and R&D innovation of SNSPD cooling technologies.
