Zusammenfassung:	The utility model relates to the technical field of water quality sampling, and discloses sampling pretreatment cooling equipment, which comprises a compressed air pipeline and a water sample pipeline, the compressed air pipeline and the water sample pipeline are sequentially arranged from top to bottom, a pretreatment heat exchanger is arranged on the lower side of the water sample pipeline, a vortex tube is arranged on one side of the pretreatment heat exchanger, and the vortex tube is connected with the compressed air pipeline. The compressed air pipeline is communicated with the vortex tube, the two ends of the vortex tube are a hot end and a cold end respectively, the cold end is communicated with the pretreatment heat exchanger, an exhaust valve is arranged at the end, away from the vortex tube, of the pretreatment heat exchanger, and the two ends of the pretreatment heat exchanger are arranged on a water inlet pipe and a water outlet pipe respectively. The water sample pipeline is communicated with the
