The ratio of phase working medium.The gas-phase working medium filled into is avoided the need for by liquid phase working fluid in gasification first section tube side 1, to obtain gas phase work
The problem of matter.The heat exchanger effectiveness of leading portion tube side 1 in evaporator can be effectively improved.
The first section tube side 1 is mixing tube side and/or the endpiece tube side 1 is mixing tube side.
First section tube side 1 is the inflow segment of working medium in evaporator, and endpiece tube side 1 is the outflow section of working medium.Flow into first section tube side 1
Working medium be main liquid phase working medium, the main gas-phase working medium of working medium of outflow endpiece tube side 1.Based on this, first section tube side and endpiece pipe
It is mixing tube side that high mass dryness fraction pipe and low mass dryness fraction pipe in journey, which can be merged into a tube side, the i.e. tube side,.Mix the replacement of tube side
Integrated model can be simplified, cost is saved.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that coming for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
