摘要

背景在用液氮冷却样品的过程中会出现膜沸腾现象，这限制了热传递并降低了冷却速度。本研究开发了一种方法，通过在冷却时用一层医用纱布包裹法国吸管 (FS) 来消除膜沸腾，从而增强对流传热。使用数值模型研究了该方法的热力学机制。结果基于传热和结晶方程的数值模拟表明，用医用纱布包裹法国秸秆可抑制薄膜沸腾。实验验证表明，使用包裹的 FS 可以提高冷却速度和细胞存活率。结论数值模拟和实验验证表明，用医用纱布包裹 FS 能更好地进行细胞冷冻保存。Doi.org/10.54680/fr23510110312.

Enhanced heat transfer by medical gauze for cell vitrification with French straw.

BACKGROUND Film boiling occurs in the cooling process of samples with liquid nitrogen, which limits heat transfer and decreases the cooling rate. OBJECTIVE AND METHODS The study developed a method to enhance convective heat transfer by wrapping the French straw (FS) with a layer of medical gauze upon cooling to eliminate film boiling. A numerical model was used to study the thermodynamic mechanism in the method. RESULTS Numerical simulation based on heat transfer and crystallization equations indicated that wrapping the FS with medical gauze could suppress film boiling. Experimental verification showed the increased cooling rate and better cell survival when wrapped FS was used. CONCLUSION Numerical simulation and experimental verification demonstrated the efficacy of wrapping FS with medical gauze for better cell cryopreservation. Doi.org/10.54680/fr23510110312.
