Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of direct vapor compression refrigeration system for X-ray pipe that the present invention proposes.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to specification word to make those skilled in the art.
Please refer to Fig. 1, the invention provides a kind of direct vapor compression refrigeration system for X-ray pipe, comprise: X-ray tube support housing 1, it is cavity cylindrical shell, coaxial installation X-ray tube 2 in described X-ray tube support housing 1, and described X-ray tube 2 axial rotation, and in the middle part of described X-ray tube support housing 1 sidewall, symmetry offers refrigerant inlet 3 and refrigerant outlet 4; Compressor 5, described compressor is provided with import and outlet, and described compressor 5 import is communicated with described refrigerant outlet 4; Condenser 6, described condenser is provided with import and outlet, and described condenser 6 import and described compressor 5 outlet; Choke valve 7, described choke valve is provided with import and outlet, and described choke valve 7 import and described condenser 6 outlet, and described choke valve 7 outlet is communicated with described refrigerant inlet 3; Wherein, described X-ray tube support housing 1, compressor 5, condenser 6, choke valve 7 are positioned at described toroidal cavity housing 8.
In the present invention:
Cold-producing medium adopts the one in the cold-producing medium that the boiling points such as R-11, R-123 are lower.
The low-pressure low-temperature both vapor compression sucked from refrigerant outlet 4 is high-pressure and high-temperature steam by compressor 5.
High-pressure and high-temperature steam after compressing through compressor 5 is condensed into high pressure low temperature liquid refrigerant by condenser 6.Condenser 6 adopts Air-cooled Condenser.
Choke valve 7 transfers high pressure low temperature liquid refrigerant to low-pressure low-temperature liquid refrigerant by expansion, and low-pressure low-temperature cold-producing medium is entered in X-ray tube support housing 1 by flexible steel in flat section tubing and refrigerant inlet 3.
