Abstract

The utility model relates to a compound thermal insulation structure of the air-handling unit frame of the central air-conditioning, the air-handling unit is assembled by the metal section steel frame and the warming plate, which is characterized in that the part which forms the cold, hot bridge in the mental frame is cut a section, the intercepted position is arranged in the girth border of the mental frame, according to the different positions of the mental frame in the whole shape of the air-handling unit, the intercepted position in the girth border of the mental frame at least has one. The space around the girth border of the mental frame is fully filled with the materials of weak thermal conductivity. The space cut by the girth border of the mental frame is also fully filled with the materials of weak thermal conductivity.

Description

The compound insulation structure of central air-conditioner wind cabinet frame work

Technical field

The utility model relates to the insulating structure of air-conditioning wind cabinet, particularly at the compound insulation structure of central air-conditioner wind cabinet frame work.

Background technique

The wind cabinet of central air-conditioner is the power position of cold (heat) wind, and it is a cabinet type structure, and interior dress blower fan leaves inlets and putlets of ventilation simultaneously, and cabinet is assembled by framework and warming plate.Nonmetallic material such as framework useable glass steel are made, its advantage is to avoid the formation of cold (heat) bridge (cold (heat) bridge refers to and the position that cold (heat) is faster transmitted occurs in thermal insulation layer), high insulating effect, shortcoming is the strength deficiency of nonmetallic material, structure is firm inadequately, uses limited at air quantity and all bigger occasion of blast.Then intensity is good to make framework with metallic material, sound construction, but be easy to generate cold (heat) bridge, heat insulation effect is descended.

Summary of the invention

The purpose of this utility model provides a kind of employing metallic material framework, but can eliminate the compound insulation structure of the central air-conditioner wind cabinet frame work that cold (heat) bridge forms, its technological scheme is as follows: the compound insulation structure of central air-conditioner wind cabinet frame work, the wind cabinet is assembled by metal section framework and warming plate, it is characterized in that the position that forms hot and cold bridge on the metal framework is clipped one section, its intercept place is positioned on the perimeter side of metal section.According to the different parts of metal framework in wind cabinet global shape, the intercept place is at least a place on the metal section perimeter side.The material of falling heat-transfer difference in the space that the metal section perimeter side is surrounded.The metal section length of side is by the also material of falling heat-transfer difference in the space of intercept.

Description of drawings

Fig. 1 is that the transverse section is the square metal section enforcement structure in wind cabinet corner;

Fig. 2 is that the transverse section is the enforcement structure of the metal section of abnormity in wind cabinet corner;

Fig. 3 needs the embodiment of lengthening wind cabinet at the lengthening position.

Embodiment

Referring to Fig. 1, square metal section bar 1 splices the cabinet that becomes a common practice with heat preservation plate material 2, will constitute the path (promptly cold (heat) bridge) that external cooling (heat) transmits in the cabinet on the metal section 1 and cut off two places 3 and 4, and the length of intercept can be determined according to the factors such as heat-conducting property of selected section bar.Can be full of the material 5 of the good and poor thermal conductivity of intensity in the section bar peripheral space, its purpose one is to strengthen heat insulation effect; The 2nd, increase the section bar rigidity.By cold (heat) bridge position of intercept, not filler, the also material of falling heat-transfer difference.The warming plate appearance can be added panel beating 6, increases the intensity of sheet material.

Fig. 2 is two section bar combinations, constitutes the framework of wind cabinet corner jointly.The intercept place of section bar 7 is 8, and the intercept place of section bar 9 is 10.Two intercept places 8 and 10 necessary all or part of coincidences can guarantee that just the path that cold (heat) is transmitted is completely severed, and promptly could eliminate cold (heat) bridge fully.

Among Fig. 3, the intercept place of section bar 11 is 12, and section bar 13 intercept places are that 14, two intercept positions also must all or part ofly overlap.Among Fig. 2,3, the same Fig. 1 of all the other labels.Can find out from above three embodiments, the shape difference of section bar and section bar be the present position difference in wind cabinet frame work structure, the position and the quantity that form cold (heat) bridge are also inequality, it also may be a place, also may be two places, as long as there is the position that forms cold (heat) bridge circuit footpath all must intercept, Here it is inventive point of the present utility model place, the material of the poor thermal conductivity of filling can be PVC, nylon etc. in the section bar, filler preferably and the section bar inwall fit tightly, being foaming or bonding among Fig. 1, is that tenon embedding formula is pegged graft among Fig. 2,3.

Claims

1, the compound insulation structure of central air-conditioner wind cabinet frame work, the wind cabinet is assembled by metal section framework and warming plate, it is characterized in that the position that forms hot and cold bridge on the metal framework is clipped one section, and its intercept place is positioned on the perimeter side of metal section.

2, the compound insulation structure of central air-conditioner wind cabinet frame work according to claim 1 is characterized in that the intercept place is at least a place on the metal section perimeter side according to the different parts of metal framework in wind cabinet global shape.

3, the compound insulation structure of central air-conditioner wind cabinet frame work according to claim 1 and 2 is characterized in that the material of falling heat-transfer difference in the space that the metal section perimeter side surrounds.

4, the compound insulation structure of central air-conditioner wind cabinet frame work according to claim 3, its feature metal section length of side is by the also material of falling heat-transfer difference in the space of intercept.
