Specifically, the body 100 includes the first surface layer 110 and the second surface layer 120 being oppositely arranged, wherein the first surface layer
110 and second surface layer 120 be respectively provided with certain thickness, its specific thickness parameter enters according to the different application field of aluminium alloy extrusions
Row selection is applicable.There is certain clearance space between the first surface layer 110 and the second surface layer 120 that are oppositely arranged, that is to say, that
First surface layer 110 and the second surface layer 120 can surround a profile cavity.In one embodiment, first surface layer 110 with it is described
Multiple ribs 130, the two neighboring rib 130 and first surface layer 110 and institute are arranged at intervals between second surface layer 120
The second surface layer 120 is stated formed with cavity 140.It is spaced and sets in the profile cavity that the first surface layer 110 is formed with the second surface layer 120
Multiple ribs 130 are put, multiple cavities 140 are divided into by the setting profile cavity of multiple ribs 130.For example, pass through
The multiple cavities 140 that the segmentation of rib 130 is formed can be triangular cavity, or polygon cavity or rectangular cavities etc.,
The different shape of cavity is determined with specific reference to the set-up mode of rib.The effect for being provided with rib 130 is to ensure aluminium alloy

In order to reduce the heat exchange efficiency of aluminium alloy extrusions cavity, and insulator 200 is easily installed in the sheet of aluminium alloy extrusions
In body 100.For example, the cavity 140 has openend 150, the openend 150 that the insulator 200 passes through the cavity 140
It is arranged at the madial wall of the cavity 140.It is understood that the both ends of cavity 140 are respectively provided with the one of opening or cavity 140

In another embodiment, as shown in figures 1 to 6, a kind of car body building enclosure 20, including the aluminium alloy extrusions knot
Structure 10.For example, by bending aluminium alloy section structure 10 or using other modes aluminium alloy sections structure 10, to form car
Body building enclosure 20.Specifically, aluminium alloy section structure 10 includes body 100 and insulator 200.Wherein because body 100 is
The higher aluminium alloy extrusions of thermal conductivity so that the heat-proof quality of car body building enclosure is poor.For example, body 100 is included by first
The cavity 140 that surface layer 110, the second surface layer 120 and multiple ribs 130 are formed, the cavity 140 have an openend, it is described every
The madial wall that hot body 200 passes through cavity 140 described in the openend 150 of the cavity.Because cavity 140 is existed by openend
Stronger cross-ventilation can be formed inside it, so that it is outer to spread outward to that car body goes along with sb. to guard him for the inner side temperature that car body is gone along with sb. to guard him
Portion, so that the heat-proof quality of car body building enclosure further declines.Especially by by the good aluminium alloy type of heat conductivility
Material bending process into car body building enclosure be adapted shape and structure, you can be applied to such as high ferro go along with sb. to guard him processing it is medium its
The car body of his type.Then when operation of air conditioner in car body, the conductive heat loss of car body building enclosure will be reduced effectively, air-conditioning in car body

Outside entire thermal resistance (the R)=car body extraneous air and aluminium alloy extrusions outside wall surface convective heat transfer resistance (R1)+aluminium alloy extrusions of structure
Wall thermal conduction resistance (R2)+rib thermal conduction resistance (R3)+R3* cavitys thermal-convection resistance (R4)/(R3+R4)+aluminium alloy extrusions itself
Air and aluminium alloy extrusions internal face convective heat transfer resistance (R6) in internal face thermal conduction resistance (R5)+car body itself.Wherein R1, R3
And R6 is definite value, heat output=(outdoor temperature-indoor temperature)/entire thermal resistance, it is therefore desirable to increase aluminium section bar heat transfer resistance, so as to
The temperature difference of inside cavities wall is reduced, suppresses the generation of free convection, so as to reduce the heat exchange efficiency in cavity, reaches reduction car body
The purpose of enclosure structure heat transfer coefficient.
Before car body sets heat-barrier material, because aluminium alloy thermal conductivity is higher, inside cavities wall outside the car body
Temperature temperature close to outside car body；The temperature of the madial wall of cavity in car body is greatly close to car body temperature.The temperature difference in cavity
It is larger, cause free convection.Therefore when setting insulator in the inner chamber of aluminium alloy extrusions so that in the cavity outside car body
The Wen Duxiajiang of side wall, i.e. high-temperature part Wen Duxiajiang, and the temperature rise of the madial wall of the cavity in car body are that is, low
The temperature rise of isothermal segment, so that the temperature difference is effectively reduced in cavity.And because the generation of free convection is because of thermal current
Rise, cold airflow declines, and causes to form stronger free convection in cavity, that is to say, that the driving force of free convection is the temperature difference.
For example, by the way that during setting heat-barrier material 200, the temperature difference effectively reduces in cavity 140, therefore in the cavity 140 of aluminium alloy extrusions
Free convection in cavity can be effectively reduced, so as to effectively reduce the heat exchange efficiency in aluminium alloy extrusions cavity, car body is improved and encloses
Protection structure integral heat-insulation property.
Above-mentioned aluminium alloy section structure 10 and car body building enclosure 20, pass through the inner side of the cavity 140 in aluminium alloy extrusions
Wall attaches certain thickness insulator 200, to increase the heat transfer resistance of aluminium section bar, so as to reduce the temperature difference in cavity 140, and suppression
The generation of free convection processed, the heat exchange efficiency in cavity 140 is then reduced, the entirety for reaching raising car body building enclosure is heat-insulated
Performance.So in car body operation of air conditioner, because the conductive heat loss of car body building enclosure reduces, the sky in car body is then reduced
Adjust load so that place capacity is not too large, and power consumption is smaller when air-conditioning system is run.
In a wherein embodiment, in order to obtain preferable effect of heat insulation, the insulator 200 is filled with the chamber
The madial wall of body 140；For example, the insulator 200 is filled with madial wall and the insulator 200 in the cavity 140
Air bladder or hollow groove are internally provided with, wherein, if dry gas, preferably inert gas in the air bladder be present, such as
Helium；For example, the insulator 200 has the first insulation surface for being in contact with the first surface layer 110, and with the second surface layer 120
The second insulation surface being in contact；For example, the insulator 200 be provided between its first insulation surface and the second insulation surface it is some
Hollow groove, and distribution sets some air bladders between each hollow groove；And for example, the insulator has and the first face
The first insulation surfaces that are in contact of layer 110, in the second insulation surface being in contact with the second surface layer 120, with the two neighboring rib
The 3rd insulation surface that is in contact of a rib, and the 4th to be in contact with another rib in the two neighboring rib
Insulation surface；For example, the insulator is provided with some hollow grooves, Yi Ji between its first insulation surface and the second insulation surface
Distribution sets some air bladders between each hollow groove.So, can be on the premise of external volume not be increased, hence it is evident that lifting
Effect of heat insulation, enable to the temperature difference in cavity to reduce 70%~80%, and due to the design of hollow groove and air bladder, ensuring
While effect of heat insulation, it is also beneficial to reduce the heat-barrier material dosage of insulator and reduces the weight of insulator.
In order to solve to set insulator in the less aluminium alloy extrusions cavity in space, the problem of to overcome processing difficulties,
For example, the insulator 200 is heat-fused in the madial wall of the cavity, for example, the insulator 200 includes heat molten type insulator.
I.e. insulator 200 uses heat-fusible materials, and because the characteristics of heat-fusible materials is, temperature reaches to a certain degree, will melt, example
If temperature is up to 110 DEG C, itself there is adhesiveness after thawing, and be used as fluid after melting, understand due to gravity, that is, heat
When, face is attached under, and heat-fusible materials are upper, so as to equably be laid on the madial wall of cavity 140.As shown in Fig. 2
The inwall of cavity 140 of side where second surface layer 120 sets insulator 200, and it is the state for not carrying out heating fusing, it should
Understand, under normal temperature state, insulator 200 is with certain thickness blocks.As shown in figure 3, when in aluminium alloy extrusions
The second surface layer 120 when being heated, block insulator 200 is gradually fused into flow-like, is flowed to other directions of the side wall layer
Dynamic, under gravity, fluid equably can flow to all directions, the everywhere until being attached to the side wall.Then cool down
After certain time so that flow-like insulator 200 is cooled into block insulator, is firmly attached in the side wall.Such as Fig. 4 institutes
Show, invert aluminium alloy extrusions, body processing attachment, the inside cavities wall where the first surface layer 110 are thermally shielded to its another side
Upper setting insulator 200.As shown in figure 5, the first surface layer 110 of heating so that the fusing flowing of insulator 200 for being arranged at the side is attached
In the side wall, finally cooled down.Selected one or both sides wherein while processed to set with specific reference to being actually needed
Put insulator.It should be noted that usually, after heat-fusible materials are melted, it is attached at the madial wall of aluminium alloy cavity 140, patch
It is attached more firm, and heat-barrier material lighter in weight, power caused by General Oscillation, it is insufficient to allow it to come off in aluminium alloy cavity
Inwall.
The madial wall of aluminium alloy extrusions cavity can be quickly and uniformly attached in order to further improve heat-fusible materials,
For example, the heat molten type insulator 200 is heat-fused in the madial wall of the cavity 140 by electrical heating paster.It is being configured
Insulator 200 is uniformly attached at the outer surface of aluminium alloy extrusions by electrical heating paster, passed through after the madial wall of cavity 140
The heat-barrier material block of electrically heated mode heating and melting inside cavity, it is set to be evenly affixed to cavity under gravity after melting
On madial wall.And for example, the heat molten type insulator is heat-fused in the madial wall of the cavity 140 by thermal current jet.Pass through
Thermal current is sprayed into cavity 140, utilizes the high temperature melt heat-barrier material block of thermal current.In order to further speed up heat-fusible materials
Melting rate, for example, the heat molten type insulator is heat-fused in the madial wall of the cavity 140 by infrared heater.It is i.e. sharp
Heat-barrier material is heated with infrared heater, because the efficiency of heating surface of infrared heater is very fast in itself, therefore utilizes infrared heater
Mode of heating can effectively accelerate the hot melt speed of heat-barrier material, so as to effectively lifted aluminium alloy extrusions set insulator plus
Work efficiency rate.
The step of being heat-fused in the madial wall of aluminium alloy extrusions cavity on insulator is that as shown in Figures 2 to 5, aluminium is closed
Metal type material 10 is placed horizontally at ground, that is, the first surface layer 110 or the second surface layer 120 is contacted with ground, so by insulator
200 are positioned over a medial surface of the cavity 140 close to ground, heat aluminium alloy extrusions by the firing equipment of peripheral hardware so that heat-insulated
Body 200 is heated to be melted, and is equably flowed to a medial surface of cavity, after insulator is melted completely, is stopped under gravity
Only heat, after standing cooling aluminium alloy extrusions for a period of time so that insulator 200 is firmly adhered to the aluminium alloy extrusions of side
The madial wall of cavity 140.Overturning aluminium alloy extrusions so that another surface layer contacts with ground, similarly heated using aforesaid way,
Insulator is cooled down, so as to complete the good installation of insulator and aluminium alloy extrusions.
In order to which aluminium alloy extrusions preferably is gone along with sb. to guard him into manufacture field applied to car body, effectively suppress the cavity of aluminium alloy extrusions
Interior cross-ventilation, for example, the insulator 200 is respectively arranged at first surface layer 110 towards the one side of the cavity 140
And second surface layer 120 is towards the one side of the cavity 140.It should be understood that in the cavity of aluminium alloy extrusions the temperature difference compared with
Big part is the cavity 140 relative with the second aspect 120 with the first surface layer 110 that body inner side and outside directly contact respectively
Two madial walls, therefore, when on the two madial walls set insulator 200 when, it is higher so as to be effectively reduced thermal conductivity
Aluminium alloy extrusions cavity 140 in cross-ventilation caused by heat loss.With described in experiment process as described above, herein no longer
Repeat.Here, it should be noted that insulator 200 can only be arranged at first surface layer 110 towards the cavity 140
Or insulator 200 can only be arranged at second surface layer 120 towards the cavity 140 while.I.e. insulator 200 can
To be provided only in cavity 140 madial wall, but heat-insulated material only is set in a madial wall of aluminium alloy extrusions cavity 140
Material, then aluminium alloy entirety heat transfer resistance is still relatively low, and its heat conductivility is heat-insulated not as good as being set on relative two madial walls of cavity
The effect that material strips are come.It can specifically select to be applicable according to the needs of different car body building enclosures.And led for high ferro manufacturing technology
Domain, high ferro building enclosure should use relative two madial walls in aluminium alloy extrusions to set heat-barrier material, so as to advantageously reduce height
The power consumption of air-conditioning system in iron.
In order to further strengthen suppressing the cross-ventilation in aluminium alloy extrusions cavity, avoid causing car body building enclosure larger
Heat loss, for example, the insulator 200 is arranged at the two sides of each rib 130.Relative two i.e. in cavity 140
On the basis of madial wall sets insulator 200, also set on two ribs 130 being oppositely arranged for forming each cavity 140
It is equipped with insulator 200.Certainly it should be noted that although setting insulator 200 on rib 130, have when being heated
Certain difficulty, it is unfavorable for installing.But each side in cavity 140 can be strengthened suppressing when being respectively provided with insulator 200
Cross-ventilation in cavity 140 so that the temperature difference of the various pieces in cavity 140 further reduces, so can be further effective
Suppress the generation of free convection, then reduce further the heat exchange efficiency in cavity, the overall thermal conductivity of car body building enclosure
Can effectively it be lifted, then the power consumption of the air-conditioning system in car body is further reduced, and can so reduce air conditioner load.
Therefore, ensure body profile material, intensity and car body weight it is constant under conditions of, significantly improving car body heat-proof quality turns into car
The key of body air conditioner system energy saving.
In order to ensure insulator can rapid melting be attached at the inside cavities wall of aluminium alloy extrusions, for example, described heat-insulated
The thickness of body 200 is less than or equal to 10 millimeters.For example, the thickness of insulator 200 is 5 millimeters, for example, the thickness of insulator 200
For 2 millimeters.Due to the thickness of insulator 200 it is thicker when, be unfavorable for quick heating fusing, so as to influence aluminium alloy extrusions and insulator
Installation effectiveness.For example, the thickness of the rib 130 is less than the thickness of the insulator 200.It is understood that rib 130
During thinner thickness, it is meant that the gross weight of rib 130 is smaller, so that the weight of whole aluminium alloy extrusions is effectively dropped
It is low.And shown by test data, when the thickness of rib 130 is less than the thickness of insulator 200, it can effectively ensure that aluminium
While the stability of alloy profile structure so that aluminium alloy extrusions gross weight is lighter, so as to be advantageous to utilize aluminium alloy type
Material manufactures car body building enclosure.
In order to further strengthen the adhesive force that insulator is arranged at aluminium alloy extrusions inside cavities wall, for example, the cavity
140 madial wall offers multiple interlaced grooves, and the depth of each groove differs, recessed described in each of which
Groove depth is less than 0.5mm.For example, the depth of groove is 0.45mm.Due to adhering to after by hot melting way, insulator is melted
When the heat-barrier material of cavity inner wall is inevitably being installed or processing is bent into car body building enclosure, shaken by larger
Power causes heat-barrier material to be come off in cavity, by opening up multiple interlaced grooves in the madial wall of cavity, may be such that every
Hot material can reliably be fixedly attached to the madial wall of cavity during fusing, and because each depth of groove is uneven,
Heat-barrier material is so caused to be fused to the adhesive force of groove and be further strengthened.It is appreciated that yes, relative to setting in the plane
For putting heat-barrier material, by the way that heat-barrier material is carried out into fusing fixation in the groove of different depth, heat-barrier material is attached to aluminium conjunction
Adhesive force in golden cavity of sectional material is stronger.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
