Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
A kind of auto purification type high strength, without cold bridge purification air-conditioning process structure, as shown in Figure 1, comprises left box body 1 and right case 2 connected vertically with left box body 1; Described left box body 1 comprises left inside plate 3 and left outside plate 5; Described right case 2 comprises right inside plate 6 and right outside plate 8; High pressure flame retardant polyurethane 4 is all filled with in described left box body 1 and right case 2; Described left box body 1 is respectively equipped with left cold-prevention bridge list 9 yuan and right cold-prevention bridge unit 7 with the interior corner location that right case 2 is connected near the two, and to be connected gap place with right cold-prevention bridge unit 7 at left cold-prevention bridge unit 9 and to be provided with first order sealing 10 and second level sealing 11 from outside to inside, the outer corner location connected with right case 2 at left box body 1 is respectively equipped with left aluminium section bar 12 and right aluminium section bar 13, left aluminium section bar 12 is fixedly connected with by screw 15 with right aluminium section bar 13, and is sealed by the two pass beading 22 be arranged on left aluminium section bar 12 between left aluminium section bar 12 and right aluminium section bar 13; Described left aluminium section bar 12 is engaged by the first outer holding section with left outside plate 5, and left aluminium section bar 12 and left cold-prevention bridge unit 9 are engaged by holding section in first; Described right aluminium section bar 13 is engaged by the second outer holding section with right outside plate 8, and right aluminium section bar 13 and right cold-prevention bridge unit 7 are engaged by holding section in second.
It should be noted that, be that the cold-prevention bridge unit consisted of each aluminium section bar and high-strength PVC separates inside and outside casing, PVC itself 100% thermal insulation, so product has efficient cold-prevention bridge effect.In addition, left inside plate 3 and right inside plate 6 are all contacted with section bar by sealed, thermally insulated glue 16, so the inside and outside of boxboard does not have metal conduction at all, avoid generation cold bridge phenomenon.Therefore, by twice face compacting sealing between left and right two section bars, fixing all very good with sealing effectiveness.
Wherein, as shown in Figure 4, described first outer holding section comprises the left outside plate flange 51 that the first embedded ribs 121 and the second embedded ribs 122 and left outside plate 5 that left aluminium section bar 12 be arranged in parallel engage with the first embedded ribs 121; Described left outside plate turns over 51 front ends, limit and props up the second embedded ribs 122, like this, left outside plate engages also inconsistent with the second embedded ribs 122 again with the first embedded ribs 121 while of turning over 51, realize dual fixing effect, make left aluminium section bar 12 and left outside plate 5 fixation reliable, ensure that enough structural strengths, stability is strong.
Wherein, as shown in Figure 2, holding section comprises the first recess 19 that the first protuberance 18 and left aluminium section bar 12 that left cold-prevention bridge unit 9 is arranged engage with the first protuberance 18 in described first.
Wherein, as shown in Figure 5, described second outer holding section comprises the right outside plate flange 81 that the 3rd embedded ribs 131 and the 4th embedded ribs 132 and right outside plate 8 that right aluminium section bar 13 be arranged in parallel engage with the 4th embedded ribs 132; Described right outside plate flange 81 front end props up the 4th embedded ribs 132.Like this, right outside plate flange 81 engages also inconsistent with the 4th embedded ribs 132 again simultaneously with the 3rd embedded ribs 131, realize dual fixing effect, and make right aluminium section bar 13 and right outside plate 8 fixation reliably, ensure that enough structural strengths, stability is strong.
Wherein, holding section comprises the second recess 20 that the second protuberance 23 and right aluminium section bar 13 that right cold-prevention bridge unit 7 is arranged engage with the second protuberance 23 in described second.
Wherein, described left cold-prevention bridge unit 9 and right cold-prevention bridge unit 7 are the rectangular configuration of hollow, and described left cold-prevention bridge unit 9 is provided with the first extension 14; Described right cold-prevention bridge unit 7 is provided with the second extension 21; Sealed, thermally insulated glue 16 is all filled with between described first extension 14 and left inside plate 3 and between the second extension 21 and right inside plate 6.
Wherein, described left cold-prevention bridge unit 9 and right cold-prevention bridge unit 7 are integrated formed structure.
Because each cold-prevention bridge unit is integrated formed structure, and and between each inner panel, be filled with sealed, thermally insulated glue 16, and be provided with first order sealing 10 and second level sealing 11 and two between cold-prevention bridge unit and be provided with two pass beading 22 between section bars and seal, achieve multi-sealed, therefore, air leak rate of air curtain is extremely low, avoids generation cold bridge phenomenon.
Wherein, as shown in Figure 3, described screw 15 connects the high pressure flame retardant polyurethane 4 in left aluminium section bar 12, right aluminium section bar 13 and right case 2 from outside to inside successively; The nut of described screw 15 is in left aluminium section bar 12 outside.The nut of screw 15 is exposed on the external, and knockout screw is convenient, when avoiding the installation of built-in screw simultaneously, and airtight space, poor air permeability, the drawback that easy humidity is got rusty.
Wherein, described first order sealing 10 is the flexible PVC seal with fillet.Like this, within left and right two boxboards connect, corner naturally forms the shape of a circular arc, not easily dust stratification, be easy to do clean.
Wherein, described second level sealing 11 adopts monoblock type PU foaming sealing strip.It is firmly bonding, and rebound performance is strong, is produce high-intensity sealing by crimp, good seal with right boxboard 2, and can be resistance to-20 DEG C ~ 70 DEG C temperature, long service life.
Each aluminium section bar in the invention and each cold-prevention bridge unit and be all provided with special snap-in structure, stable connection between each aluminium section bar and each outside plate, overall construction intensity is high.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
