Such systems usually include liquid storage tank, liquid cooling pipeline and circulating pump components, and achieve rapid cooling through refrigerant phase change. At present, in order to reduce the weight and cost of the system, the pipeline of gun type liquid cooling equipment is mostly made of plastic liquid cooling pipe, but its pressure resistance is significantly lower than that of metal pipeline, which has the risk of structural failure under high pressure working condition.
