Specific embodiment
As shown in Figure 1 to Figure 3, the present embodiment includes: multiple groups heat-radiation belt 2, multiple groups flat tube 3, two headers 1 and 5, liquid storage
Tank 11, multiple spoilers 7, the first check valve 9 and overhead gage 4 and four interfaces 6,8,10 and 12, in which: in overhead gage 4
Lower section heat-radiation belt 2 and the setting of the interval of flat tube 3, two headers 1 and 5 are set to the two sides of heat-radiation belt 2 and flat tube 3, fluid reservoir 11
It is connected to the first header 1, spoiler 7 is set to the inside of the first header 1, and upper inlet 6 is connected to upper outlet 12 and with
The connection of one header 1, lower inlet 8 are connected to the first header 1, and lower outlet 10 is set to the bottom of fluid reservoir 11, and first is unidirectional
Valve 9 is located in lower inlet 8 and the connecting pipe of lower outlet 10.
As shown in Fig. 2, refrigerant upper entering and lower leaving, upper outlet 12 and lower inlet 8 are in when the present embodiment is as condenser
Closed state, high pressure gaseous refrigerant are entered in the first header 1 by upper inlet 6, and gaseous coolant fills entire first afflux
Pipe 1, spoiler 7 are assigned to gaseous coolant in every group of flat tube 3 of top split flow, are handed over by heat-radiation belt 2 and the air of circulation
Heat exchange amount becomes supercooled state/two phase refrigerants and enters in the second header 5, then assigns to the flat tube 3 in the split flow of lower part
It is interior, continue to become supercooled state refrigerant, spoiler 7 is whole by supercooled state refrigerant with the air exchange heat to circulate by heat-radiation belt 2
Entered in fluid reservoir 11 by the first check valve 9, then through lower 10 outflow of outlet.
