The specific embodiment
Describe embodiments of the invention below in detail, the example of said embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Be exemplary through the embodiment that is described with reference to the drawings below, only be used to explain the present invention, and can not be interpreted as limitation of the present invention.
Following with reference to the heat exchanger of figure 1-7 description according to the embodiment of the invention.
As shown in Figure 1, comprise inlet collecting 2, outlet header 6, flat tube 3, fin 7 and distributing pipe 1 according to the heat exchanger of the embodiment of the invention.
As shown in Figure 2, the inside of inlet collecting 2 defines refrigerant chamber S1.Certainly, in Fig. 2 and example shown in Figure 4, the whole inner chamber of inlet collecting 2 all is refrigerant chamber S1.Alternatively, as illustrated in Figures 5 and 6, the inside of inlet collecting 2 has been divided into refrigerant chamber S1 and cavity S2 (following will the detailed description in detail) by dividing plate 4.
Be provided with dispensing orifice 14 like Fig. 1-2 and 3a-3b distributing pipe 1, as shown in Figure 1, distributing pipe 1 is arranged on the outside of refrigerant chamber S1, and the inner chamber 13 over-allocation holes 14 of distributing pipe 1 are communicated with refrigerant chamber S1.Certainly, on the wall of the inlet collecting 2 that limits refrigerant chamber S1, be formed with corresponding through hole 21.
Heat exchanger according to the embodiment of the invention; Because distributing pipe 1 is not arranged in the refrigerant chamber S1 of inlet collecting 2; In other words; Distributing pipe 1 is not inserted in the cold-producing medium of inlet collecting 2, thus the installation and removal of distributing pipe 1 simple, be convenient to safeguard, can not influence each other with inlet collecting 2 inner refrigerants, improved distribution effects.
As shown in Figure 1; In example of the present invention; When distributing pipe 1 was installed on the outer wall of inlet collecting 2, dispensing orifice 14 was corresponding with through hole 21, thereby the cold-producing mediums that get into from the cryogen source (not shown) in the inner chamber 13 of distributing pipe 1 spray in the refrigerant chamber S1 through dispensing orifice 14 and through hole 21; Eliminate the gas-liquid lamination that cold-producing medium produces thus in inlet collecting 2, improved the heat exchange effect of heat exchanger.In order further to improve the distribution effects of cold-producing medium, the internal diameter of distributing pipe 1 is 0.17-0.79 with the waterpower internal diameter ratio of cold-producing medium cavity.
In order to increase the convenience of installation; In an example of the present invention; Distributing pipe 1 has formed installs foot 12, and the surface of installation foot 12 and the surface configuration of inlet collecting 2 are adaptive, thereby through foot 12 is installed distributing pipe 1 is installed on the outer wall of inlet collecting 2.For example, through installing on the outer wall that foot 12 is welded to inlet collecting 2 distributing pipe 1 is fixed on the inlet collecting 2, dispensing orifice 14 ran through foot 12 was installed this moment, and corresponding with through hole 21.
According to a concrete example of the present invention, shown in Fig. 3 a, dispensing orifice 14 can be made up of a plurality of independent opening that the compartment of terrain is formed on the distributing pipe 1, and said opening can be circular port, also can be the notch of other shapes.Alternatively, shown in Fig. 3 b, dispensing orifice 14 also can form along the length direction of distributing pipe 1 and extend the single groove that connects.Dispensing orifice 14 can form circular port, and its hydraulic diameter further improves the distribution effects of cold-producing medium thus in the scope of 0.2mm-4mm.Alternatively, the area of said dispensing orifice is 0.3-2 with the ratio of the sectional area of cold-producing medium cavity.According to the inventor's the ratio that experiment showed, above-mentioned scope, can improve the distribution effects of cold-producing medium.
According to embodiments of the invention, because distributing pipe 1 is installed on the outer wall of inlet collecting 2, therefore; The quantity that is provided with of distributing pipe 1 changes easily; For example, inlet collecting 2 can be set to a plurality of, can satisfy the heat exchanger to different refrigerant amount requirements; And through control each distributing pipe 1, the easily distribution of cold-producing medium.
In an example of the present invention; Cold-producing medium is spent between-315 degree 45 from the rightabout B and the angle between the flow direction A of cold-producing medium in flat tube 3 of the direction that dispensing orifice 14 flows out; Be arranged in the above-mentioned scope through angle, can further improve the distribution effects of cold-producing medium direction A and direction B.For example, in Fig. 2, direction B becomes 180 degree angles with direction A.Alternatively, for example in the example depicted in fig. 5, direction B becomes 90 degree angles with direction A.
As shown in Figure 4, in an optional example of the present invention, distributing pipe 1 does not form installs foot 12, but through being communicated with inlet collecting 2 interior refrigerant chamber S1 communicating pipe 5.The end of communicating pipe 5 welds with distributing pipe 1 at dispensing orifice 14 places mutually; And passing the wall of inlet collecting 2, the other end stretches in the refrigerant chamber S1; Certainly, sealing between communicating pipe 5 and the inlet collecting 2 is for example through being welded to connect communicating pipe 5 and inlet collecting 2 and sealing the slit between them.
With reference to figure 5 heat exchanger is according to another embodiment of the present invention described below.As shown in Figure 5; In the set inside of inlet collecting 2 dividing plate 4; Dividing plate 4 is divided into refrigerant chamber S1 and cavity S2 with the inside of inlet collecting 2 thus; Can not have cold-producing medium in its cavity S2, distributing pipe 1 is installed on the outer wall of inlet collecting 2, and is communicated with refrigerant chamber S1 through dispensing orifice 14 and through hole 21.Through dividing plate 4 is set, can reduce the volume of refrigerant chamber S1, further improve the distribution effects of cold-producing medium.
In the example depicted in fig. 5, distributing pipe 1 has formed installation foot 12, thereby is convenient to distributing pipe 1 is fixed on the outer wall of inlet collecting 2.
Fig. 6 shows another optional example, and in the example depicted in fig. 6, distributing pipe 1 is not installed on the outer wall of inlet collecting 2, and is arranged in the cavity S2, and through being communicated with refrigerant chamber S1 communicating pipe 5.Thus, not only the installation and removal of distributing pipe 1 are convenient, and can not receive the influence of the cold-producing medium in the inlet collecting 2, and the volume of refrigerant chamber S1 reduces simultaneously, has improved distribution effects, and the overall aesthetic of heat exchanger improves.
Below the simple operation of describing according to the heat exchanger of the embodiment of the invention.
As shown in Figure 1, cold-producing medium gets into distributing pipe 1 along direction C, is injected in the refrigerant chamber S1 in the inlet collecting 2 through dispensing orifice 14 then; Eliminated the gas-liquid lamination; Then, cold-producing medium flows towards outlet header 6 along flat tube 3, during carry out heat exchange; The cold-producing medium that lives through after the heat exchange gets into outlet header 6, discharges outlet header 6 along direction D then.
Because distributing pipe 1 is not inserted in the cold-producing medium in the inlet collecting 2, therefore with its in cold-producing medium can not influence each other, be convenient to install dismounting and safeguarding.Simultaneously, a plurality of distributing pipes 1 can be set,, can adapt to different demands refrigerant amount through controlling each distributing pipe 1.
Although illustrated and described embodiments of the invention; Those having ordinary skill in the art will appreciate that: under the situation that does not break away from principle of the present invention and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited claim and equivalent thereof.
