Embodiment 1

[0098] Such as figure 1 The shown internal combustion engine waste heat multi-stage refrigeration system includes an internal combustion engine cooling water channel carburetor 1 and an exhaust gas carburetor 2, the fluid inlet of the heating fluid channel of the internal combustion engine cooling water channel carburetor 1 communicates with the internal combustion engine cooling water channel fluid outlet, and the internal combustion engine cooling water channel carburetor The fluid outlet of the heating fluid channel of 1 communicates with the fluid inlet of the internal combustion engine cooling water channel through the liquid circulation pump 52, and the gas outlet of the heated fluid channel of the internal combustion engine cooling water channel vaporizer 1 communicates with the power fluid inlet of the jet pump 3, and the jet pump The low-pressure fluid inlet of 3 communicates with the evaporator 4, the liquid inlet of the heated fluid channel of the internal combustion...

Embodiment 2

[0100] Such as figure 2 The shown internal combustion engine waste heat multi-stage refrigeration system is based on Embodiment 1: the fluid outlet of the jet pump A32 communicates with the power fluid inlet of the subsidiary jet pump 31, and the low-pressure fluid inlet of the subsidiary jet pump 31 communicates with the subsidiary jet pump A31. The evaporator 41 communicates.

Embodiment 3

[0102] Such as image 3 The shown internal combustion engine waste heat multi-stage refrigeration system is based on Embodiment 2: the communication channel between the gas outlet of the heated fluid channel of the internal combustion engine cooling water channel evaporator 1 and the motive fluid inlet of the jet pump 3 Air compressor 10 is added on.

[0103] As a changeable embodiment, all embodiments in the present invention that do not have a compressor 10 can refer to the gas outlet of the heated fluid channel of the internal combustion engine cooling waterway carburetor 1 and the power fluid of the jet pump 3 in this embodiment. A compressor 10 is added to the communication channel between the inlets. Similarly, in all the implementations including the compressor 10, the compressor 10 can be selectively omitted.
