Include gas-liquid separation main body and liquid separation body, the gas-liquid separation main body is that the hollow circular cylinder knot of capping is arranged at bottom-open, top
Structure, the side wall upper part of the gas-liquid separation main body open up aperture connection low pressure gas liquid pipe, top closure center offer aperture with
Air entraining pipe connection, the inside of the liquid separation body are uniformly provided with the through-hole of multiple same diameters, and multiple through-holes are from described point
Liquid top reaches bottom end side and connect respectively with separating tube, and the other end of the separating tube is separately connected heat exchanger tube.
The liquid separation body is the cone structure that upper end diameter is small, lower end diameter is big, the bottom of the gas-liquid separation main body
The edge of open side and the upper end-face edge of liquid separation body weld.
Tangent position on the hollow circular cylinder of the gas-liquid separation main body close to top cover opens up aperture and the low pressure
Gas-liquid pipe connection.
The import of the other end of the separating tube and each heat exchanger tube is welded to connect.

Detailed description of the invention
Fig. 1 show the structural schematic diagram of the cooling air formula evaporator with eddy flow bleed liquid-dividing head of the utility model；
Fig. 2 is the dextrad view of Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, with the cooling air formula evaporator of eddy flow bleed liquid-dividing head, comprising:
Heat exchanger tube 1, separating tube 2, air entraining pipe 3, heating power expansion valve 4, low pressure gas liquid pipe 5, gas-liquid separation main body 6, liquid separation body
7, gas collecting tube 8, fin 9.
The cooling air formula evaporator includes heat exchanger tube 1 and fin 9, structure and usual nest plate tubular evaparator phase
Together, no longer more narrations herein.
The gas-liquid separation main body 6 and liquid separation body 7 form eddy flow bleed liquid-dividing head, and the gas-liquid separation main body 6 is bottom
Portion is opened wide, and the structure of the hollow circular cylinder body of capping is arranged at top, and the logical of multiple same diameters is uniformly provided with inside liquid separation body 7
Hole, one end edge welding of the trapezoidal roundlet at the edge and 7 one end of liquid separation body of 6 opened portion of gas-liquid separation main body, gas-liquid separation master
The cylinder of body 6 opens up aperture close to the tangent position of top cover and connect with low pressure gas liquid pipe 5, in 6 top closure of gas-liquid separation main body
The heart offers aperture and one end of air entraining pipe 3 and is welded to connect；Trapezoidal great circle one end of the other end of liquid separation body 7 opens up each small
Hole is welded to connect with one end of separating tube 2 respectively.
The other end of the air entraining pipe 3 can be to be connect with the gas vent of the connection gas collecting tube 8 of cooling air formula evaporator
It takes over and connects with the return-air of refrigeration compressor after pipe is in parallel.
The import of the other end and each heat exchanger tube of the separating tube 2 is welded to connect.
