[0025] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the utility model will be further described in detail below with the drawings.

[0026] As shown in Figures 1 to 4, Figures 1 to 4 show the structure of the first embodiment of the evaporimeter of the utility model schematic diagram, the evaporimeter includes cylinder body 1 and refrigerant shell 2, the refrigerant shell 2 is arranged around the inner cylinder surface 11 of the cylinder body 1, at least one refrigerant passage 3 is formed between the refrigerant shell 2 and the cylinder body 1; The refrigerant passage 3 is coiled on the inner cylinder surface 11 of the cylinder body 1, the condensed liquid in the refrigerant passage 3 acts on the inner cylinder surface 11 of the cylinder body 1 to realize heat exchange work outside the shell wall of the cylinder body 1; Both ends of the refrigerant passage 3 are connected with the condenser and the compressor through the pipeline.

[0027] In operation, the condenser delivers the condensed liquid to the refrigerant passage 3 through the pipeline, the condensed liquid flowing into the refrigerant passage 3 acts on the inner cylinder surface 11 of the cylinder body 1, the condensed liquid absorbs heat from the outside through the shell wall of the cylinder body 1, that is, the condensed liquid exchanges heat with the outside air, and the gas after the condensed liquid is vaporized is discharged back to the compressor through the refrigerant output pipeline 5. The condensed liquid can be guided through the refrigerant passage 3 to form a consistent flow trend, that is, a flow direction, so as to avoid vortex and resistance that hinders the flow of the condensed liquid due to inconsistent directions, thereby improving the flow speed of the condensed liquid and the heat exchange efficiency. At the same time, the condensed liquid only needs to exchange heat with the outside through the shell wall (i.e., a single layer of heat-conducting medium) of the cylinder body 1, and by reducing the heat-conducting medium, the heat conduction efficiency can be effectively improved, thereby improving the cooling performance of the evaporator, simplifying the overall structure, saving assembly space, and reducing production costs.

[0031] Preferably, the input portion 22 and the output portion 23 are both arranged at the same end of the refrigerant shell 2, so that the refrigerant input pipe 4 connected with the input portion 22 and the refrigerant output pipe 5 connected with the output portion 23 are both arranged at the same space in the cylinder 1, so that the overall structure is compact, the space occupied by the evaporator is reduced, and the space utilization of the evaporator is improved.

When working, the condensed liquid delivered by the condenser flows into the refrigerant channel 3 through the condensing input pipe, the input pipe opening 25 and the input groove 24 in sequence, so that the condensed liquid is gradually vaporized in the refrigerant channel 3 to realize heat exchange work. After the condensed liquid in the refrigerant channel 3 is vaporized, the gas generated by the vaporization is discharged back to the compressor through the output groove 26, the output pipe opening 27 and the refrigerant output pipe 5 in sequence to realize the cooling cycle work and improve the refrigeration effect of the evaporator.

When the evaporator works, the condensing liquid of the condenser flows into the refrigerant channel 3 at different positions through the input port 25 and the plurality of middle input ports 28 and acts on the corresponding positions of the inner cylinder surface 11 of the cylinder body 1, so that the low-temperature condensing liquid quickly exchanges heat at different positions of the evaporator, accelerates the circulation heat exchange rate of the whole condensing liquid, and improves the cooling efficiency of the evaporator.

[0037] As shown in Figure 6, Figure 6 shows the structure diagram of the third embodiment of the evaporator, which is different from the first embodiment shown in Figures 1 to 4, that is, the serpentine groove 21 is provided with an input part 22 and an output part 23, either of the input part 22 and the output part 23 is arranged at the middle section of the serpentine groove 21, and the other is arranged at the first end and the last end of the serpentine groove 21 respectively, and the input part 22 and the output part 23 are respectively in communication with the refrigerant channel 3 to form a refrigerant channel 3 with one input and two independent outputs or a refrigerant channel 3 with one output and two independent inputs.
