The specific embodiment
Micro-channel heat exchanger of the present utility model comprises header 1, plug 3, water inlet pipe 2, outlet pipe 4, flat tube 6, fin 5 and side plate 7.Wherein, compare with prior art shown in Figure 1, the concrete structure of header 1, plug 3, water inlet pipe 2, outlet pipe 4, flat tube 6 and fin 5 each parts is same as the prior art, equally, two headers 1 be arranged in parallel, many flat tubes 6 are parallel to each other and are preferably equidistant arrangement, thereby the two ends of each flat tube 6 are inserted respectively in two headers 1 and communicated with header 1.Be fitted with corrugated fin 5 between the adjacent flat tube 6, to increase heat exchange area, to improve heat exchange efficiency.Every flat tube 6 is flat, and inside has the two ends that an exhausting hole runs through flat tube.The length direction that axially is flat tube 6 of through hole also is the length direction of whole micro-channel heat exchanger.And the plane of a plurality of through-bore axis institute coplane of an aforementioned exhausting hole is the central plane of flat tube 6, being parallel to central plane and being the width of flat tube 6, fin 5, side plate 7 and whole micro-channel heat exchanger perpendicular to the direction of through-bore axis, is the short transverse of each parts such as whole micro-channel heat exchanger and flat tube 6 thereof, fin 5, side plate 7 perpendicular to the direction of flat tube 6 central planes.
Different is for the utility model and prior art, and side plate 7 is not straight plate structure, but has the dividing plate 710 that is parallel to flat tube 6 central planes and at least one perpendicular to described dividing plate 710 and the floor 720 that extends along flat tube 6 length directions.
First embodiment of the present utility model as shown in Figure 3.The same with prior art shown in Figure 1, side plate 7 is contained in two flat tube 6 outsides of top side, lower side in the row flat tube between two headers 1, and between side plate 7 and top side flat tube 6, side plate 7 and lower side flat tube 6 fin 5 is set respectively.Side plate 7 is by fixing with corresponding fin 5 welding.In order to add stiff stability, the two ends of side plate 7 can be connected with other fixed forms such as the header 1 on both sides weld, is threaded respectively.
Different is with prior art, as shown in Figure 4, the side plate 7 of present embodiment is not straight plate, but for extend along the flat tube length direction, cross section is the groove bar of U font, it comprises the floor 720 that the side of the square spacer plate 710 that is parallel to flat tube 6 central planes and two and two length directions of dividing plate 710 joins, floor 720 is perpendicular to dividing plate 710, and its shape of cross section as shown in Figure 4.
Because flat tube 6 is elongated structure, the as easy as rolling off a log distortion of bending by the waist makes inner through hole crimp even obstruction, thereby influences the heat exchange effect.Side plate 7 of the present utility model has additional the floor 720 along the flat tube length direction on the dividing plate 710 on plane, when dividing plate 710 has bending trend, can play the effect that pins down dividing plate, stops its distortion, makes the non-deformability of whole side plate strengthen.
Analog result by the finite element analysis simulation softward and actual drop test are as can be known; adopt the U-shaped side plate of present embodiment; can improve the counter-bending ability of side plate 7; improve integral intensity; make non-deformability strengthen; can effectively protect flat tube 6 and fin 5 between two side plates, avoid it to sustain damage.
In second embodiment of the present utility model, all structures except that side plate 7 and profile position B-B are all identical with first embodiment.The cross section of the side plate 7 of present embodiment is the C font, and it comprises dividing plate 710 and the floor 720 identical with the side plate 7 of first embodiment, comprises also that two floor 720 ends stretch out relatively and perpendicular to the flanging 730 of floor 720, its structure as shown in Figure 5.
Adopt the C shape side plate of present embodiment, make that the end of floor 720 is directly not protruding, avoid personnel when operation, to scratch skin, when strengthening side plate intensity, can play a protective role.
The 3rd embodiment of the present utility model such as Fig. 6, shown in Figure 7, the side plate 7 of present embodiment not only is installed in the outside of outermost flat tube 6, also can be contained between adjacent two flat tubes 6, is about to the former fin 5 usefulness side plates 7 that should be contained between two flat tubes 6 and replaces.For the ease of producing, safeguard and making, be contained in the height that side plate 7 total heights between two flat tubes 6 should be not more than fin 5, i.e. clearance height between two flat tubes 6.This design can guarantee that the position, hole of plug-in mounting flat tube 6 on the header 1 and spacing need not to adjust, and avoid the new header 1 of die sinking tool manufacturing separately, thereby provide cost savings.
Adopt the micro-channel heat exchanger of present embodiment, side plate 7 is arranged between the flat tube 6, can further improve the intensity of whole heat exchanger, strengthens non-deformability.According to design with calculate, under the prerequisite that guarantees exchange capability of heat, can remove one or more fins 5 and with side plate 7 replacements.
Be understandable that, side plate of the present utility model can have multiple way of realization, for example its floor can have only one or more than two, perhaps floor not necessarily is positioned on the dual-side of dividing plate of the foregoing description but is positioned in the middle of the dividing plate or near position intermediate, or floor not only has the floor that extends along the flat tube length direction, also have floor perpendicular to flat tube length direction or other angles, a plurality of floors can knit be connected into netted.In addition, can provide enough intensity for side plate in order to guarantee floor, the ratio of the height of floor and the width of dividing plate is between 0.1～0.5.
In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
