The present invention discloses a jet self-cooling device. A jet self-cooling device, comprising a housing, wherein an upper end and a lower end of the housing are respectively provided with a main inlet and a main outlet, and a side wall of the housing is provided with: A gas-phase outlet is disposed, a jet wall is disposed inside the housing in a circumferential direction, and a plurality of pores are formed in the jet wall to jet a mainstream working material by a pressure difference between the mainstream inlet and the gas-phase outlet. The present invention adopts a simple device structure to achieve cooling of a liquid working substance, and satisfies the requirement for a low-temperature refrigerant during experimental research or development of a new circulation system, and adopts the method and device in a conventional refrigeration circulation, which helps to reduce the area of an evaporator, reduce the volume of a unit, and reduce processing costs.
