Abstract

The utility model is an anti-cold-bridge hermetically-sealed access door of central air-conditioning. Usually, the existing access door is directly hinged on a casing, the confinement effect is bad, the employed door panel is bad in heat-insulating property, and the phenomenon of 'cold-bridge'is serious, thereby the energy loss is large and the heat exchange rate is low. The utility model consists of a door panel and a door frame which is equipped on the outer the door panel, the two portions are connected via hinge connection, and the character of the utility model is that the door frame is arranged with a groove which is studded with a sealing strip. The door panel comprises a front door panel, a rear door panel and a polyamide-ester foaming which is imbedded between the front door panel and the rear door panel, the edge of the front door panel and the rear door panel compose a convex ring, the convex ring is pressed on the sealing strip. Due to the sealing strip is imbedded in the groove of the door frame and engaged with the groove on the door panel and thereby the sealing effect is well. The polyamide-ester foaming imbedded between the front door panel and the rear door panel can efficiently prevent the phenomenon of 'cold-bridge'happening, the loss of the heat exchange equipment is small and the heat exchange rate is high at run time.

Description

Caution cool-bridge access door of center air-condition

[technical field]

The utility model relates to a kind of access door, especially a kind of anti-cold bridge sealing access door that is used on the central air-conditioning.

[background technology]

In existing central air conditioner system, heat-exchange apparatus is arranged in the casing of sealing usually, to reduce energy loss, improves the efficient of heat exchange.For the ease of these heat-exchange apparatus are carried out maintenance and repair, some access doors that can open and close flexibly are installed on casing usually, these access doors directly are hinged on the casing usually, and sealing effectiveness is bad; And the door-plate heat-proof quality that adopts is bad, and " cold bridge " phenomenon is serious, and energy loss is big, and heat exchanger effectiveness is low.

[summary of the invention]

The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the technological deficiency that existing product exists, anti-cold bridge sealing access door on a kind of central air-conditioning is provided,, avoids the generation of " cold bridge " phenomenon to strengthen sealing effectiveness, reduce energy loss, improve the efficient of heat exchange.

The technical scheme that the utility model is taked is: caution cool-bridge access door of center air-condition, comprise that door-plate and frame be located at its outer doorframe, and the two is connected through the hinge, and it is characterized in that doorframe is provided with annular groove, and annular groove is embedded with sealing strip; Described door-plate comprises front door, Rear Door and is folded in therebetween polyamine fat foaming, and the edge of forward and backward door-plate forms a bulge loop, and bulge loop is pressed on the sealing strip.Because sealing strip is embedded in the annular groove on the doorframe, and cooperate good sealing effect with bulge loop on the door-plate; Folder is established the foaming of polyamine fat between the forward and backward door-plate, has effectively prevented the generation of " cold bridge " phenomenon, and the energy loss during the heat-exchange apparatus operation is little, the heat exchanger effectiveness height.

Described caution cool-bridge access door of center air-condition is characterized in that front door is provided with outer chimb, and Rear Door is provided with inner raised edge, is provided with the PE bar between the inside and outside chimb.

Described caution cool-bridge access door of center air-condition is characterized in that Rear Door is supported in the rear side of front door by locating piece, forms the cavity that holds the foaming of polyamine fat between the forward and backward door-plate; Offer foam hole on the outer chimb on the front door, offer corresponding through hole on the door-plate of front and back.

Described caution cool-bridge access door of center air-condition is characterized in that leaving the gap between outer chimb and the doorframe, and the doorframe outside is provided with the PE layer.

Described caution cool-bridge access door of center air-condition is characterized in that described doorframe is provided with interior flanging and outer flanging, and annular groove is formed by interior flanging, offers screw hole on the outer flanging.

Described caution cool-bridge access door of center air-condition is characterized in that offering the slot hole on front door and the doorframe, and the two ends of hinge are connected in the slot hole.

The utility model embeds sealing strip in the annular groove on the doorframe, and cooperates good sealing effect with bulge loop on the door-plate; Folder is established the foaming of polyamine fat between the forward and backward door-plate, has effectively prevented the generation of " cold bridge " phenomenon, and the energy loss during the heat-exchange apparatus operation is little, the heat exchanger effectiveness height.
