The function of above structure mainly is to adopt the combined method in different equivalents aperture to strengthen the resistance vapour ability and the fluid flow regulating power of leakage resistance vapour device from pore structure, main aperture 12 guarantees the basic leakage ability of leakage resistance vapour device, via hole 13 guarantees the fluid flow regulating power of leakage resistance vapour device, at amount of liquid hour, intercept the steam circulation by the fluid-tight effect.Directly adopt above-mentioned loose structure substrate 11, remarkable advantages is arranged solving heat exchanger system machine oil obstruction substrate 11 aspects.
Embodiment 5:
Shown in Figure 14,15, present embodiment is in the main aperture 12 that is provided with on the substrate of making 11 and the via hole 13 porous media core 4 to be set.In the less heat exchanger of refrigerant flow,, need littler pore structure to guarantee the resistance vapour ability of pore structure because the condensate liquid flow is less, filling porous dielectric core 4, can under the condition that does not change pore structure, strengthen the effect of pore surface tension force, strengthen resistance vapour ability.The swabbing action of porous media core 4 also can guarantee the circulation of condensate liquid simultaneously, realizes the separatory effect under the little refrigerant flow.
Embodiment 6:
Shown in Figure 16,17, present embodiment is in main aperture and via hole intersect the aperture that presents " plum blossom " hole shape structure porous media core 4 to be set, and this structure can possess on the foregoing description 3 characteristics bases, has strengthened the resistance vapour effect of device.
Embodiment 7:
Shown in Figure 18,19, present embodiment is to intersect under the situation about also being provided with when presenting " plum blossom " hole shape structure with the disjoint via hole 13 of main aperture at main aperture 12 and via hole 13, is provided with porous media core 4 in each hole.This structure is under the situation of the foregoing description 4 described textural associations, has guaranteed that when circulation area increases leakage resistance vapour device has regulating power at bigger sphere of circulation, has guaranteed the resistance vapour effect of device simultaneously.
Embodiment 8:
Shown in Figure 20,21, present embodiment is similar to Example 1, but adopts porous media material as substrate 11, cooperates the structure of main aperture 12, via hole 13, loose structure by porous media material itself guarantees resistance vapour ability, and through-hole structure guarantees leakage shunting ability.
In the various embodiments described above, leakage resistance vapour device 10 adopts solid material identical with header 2 cross sections or solid porous medium as substrate 11, is generally metal material, guaranteeing not have under the tight prerequisite that contacts of leakage with described header, also can adopt other materials.Substrate directly is embedded in the position of determining in the header, generally adopts welding manner to fix to the metal material substrate, and structure is greatly simplified.Hole on the porous plate can adopt the hole of different equivalents aperture, structure to constitute, and each pore structure becomes the equivalent aperture, also can be with the equivalent aperture, and porous media can adopt porous media that the powder particle sintering makes or silk screen etc.
Embodiment 9: adopt the inventive method to use in various heating-cooling equipments.
As shown in figure 22, present embodiment is the application in liquid separating air condenser, the header 2 that leakage resistance vapour device 10 is installed has substituted separating tube and the header structure in the former liquid separating air condenser, the header 2 of one side connects opposite side header 2 by heat exchanger tube, interlock in the left and right sides header 2 to inlay and be fixed with a plurality of leakages and hinder vapour devices 10, a plurality of vapor-liquid separation space that order was communicated with about both sides header 2 was separated into, first order header 2 connects a feed tube 3, both sides header 2 bottoms of the bottommost drain pipe 4 that is connected in parallel, heat exchanger tube 1 is provided with fin 5.
When the present invention uses, condensate liquid by heat exchanger tube 1 heat exchange generation, in header 2,, the gravity effect hinders vapour device 10 tops because converging to leakage, continuous accumulation along with condensate liquid, condensate liquid can at first be drained by main hole with larger diameter 12 under the gravity effect, the less via hole 13 of diameter can be sealed by the liquid film that a spot of condensate liquid forms, prevent that effectively steam from passing through, and it is bigger to work as condensing liquid quantity, the condensate liquid of assembling on leakage resistance vapour device 10 tops increases, and liquid layer thickness increases, and the pressure head that gravity produces increases, the through-current capability of the via hole 13 of minor diameter is activated, and can effectively reduce the excessive gathering of condensate liquid on liquid distributing device top.The negotiability experiment in hole shows that under certain liquid level condition, the condensate liquid flow of through hole roughly is directly proportional with the through hole circulation area, therefore characterizes the negotiability of leakage resistance vapour device 10 by defined parameters porosity S,
