The invention discloses an artificial stratum freezing device and method based on a heat pipe, the artificial stratum freezing device comprises an energy storage device, a phase change device, a gas dispersing device and a heat pipe freezing system, and the working principle is as follows: the energy storage device is used for storing a liquid refrigerant; the liquid refrigerant flows into the phase change device from the energy storage device and is subjected to phase change in the phase change device to become a gaseous refrigerant; the gaseous refrigerant transmits the cooling capacity to the heat pipe freezing system, and the temperature in the phase change device is gradually increased; and when the temperature in the phase change device rises to the temperature which does not meet the freezing requirement, the gaseous refrigerant agent is exhausted through the air dispersing device. The heat pipe is used for replacing a traditional freezing pipe for circulating a huge amount of refrigerant, and the leakage risk of the circulating refrigerant of the traditional freezing pipe is avoided; a controllable cold supply system is researched and developed, so that a cold supply refrigerant is subjected to phase change outside a freezing system, the problems of unstable temperature caused by phase change of a gaseous refrigerant in a pipe and cooling capacity waste existing in a traditional freezing method are solved, and the purpose of uniform development of a frozen soil curtain at a low temperature is achieved.
本发明公开了一种基于热管的人工地层冻结装置和方法，包括储能装置、相变装置、散气装置和热管冻结系统，工作原理如下：储能装置用于储存液态冷媒剂；液态冷媒剂从储能装置流入相变装置，并在相变装置中发生相变，成为气态冷媒剂；气态冷媒剂将冷量传输给热管冻结系统，相变装置内部的温度逐渐升高；当相变装置内部的温度升高至不符合冻结要求时，气态冷媒剂通过散气装置排走。本发明用热管代替了循环巨量冷媒剂的传统冻结管，解决了传统冻结管循环冷媒剂泄露风险；研发可控式供冷系统，使得供冷冷媒剂在冻结系统外发生相变，解决了气态冷媒剂在管内相变造成的不稳地温度以及传统冻结法存在的冷量浪费问题，达到了低温下冻土帷幕均匀发展的目的。
