A heat-insulating high-speed rail window aluminum alloy profile

Abstract

The invention provides a thermal insulation type high-speed rail train window aluminum alloy profile which comprises a middle frame. The middle frame comprises a first profile body, a second profile body, a first thermal insulating strip and a second thermal insulating strip, and the first profile body comprises a first aluminum plate and a second aluminum plate which are connected through a third aluminum plate and a fourth aluminum plate; the second profile body comprises a fifth aluminum plate and a sixth aluminum plate which are connected through a seventh aluminum plate and an eighth aluminum plate; the side, far away from the sixth aluminum plate, of the fifth aluminum plate is provided with a first vertical plate and a second vertical plate, the other end of the first thermal insulating strip is connected with the first vertical plate in a matched mode, one end of the second insulating strip is connected with the second aluminum plate in a matched mode, and the other end of the second insulating strip is connected with the second vertical plate in matched mode. By means of the thermal insulation type high-speed rail train window aluminum alloy profile, transfer of heat between the profile bodies is effectively prevented, the heat can be completely isolated, the sound insulation effect is good, the strength of an aluminum alloy profile frame is high, denaturation is not prone to occurrence, and structural connection is firm.

Description

technical field [0001] The invention relates to the technical field of aluminum profiles for high-speed rail, in particular to a heat-insulating aluminum alloy profile for high-speed rail windows. Background technique [0002] Aluminum alloy profiles are often used in the installation of doors and windows. In order to ensure that the temperature inside the high-speed rail car is basically consistent, the thermal insulation effect of the aluminum alloy profile is particularly important. In the cold winter, the temperature inside the high-speed rail car is higher than the temperature outside the high-speed rail car. The heat inside the high-speed rail car is quickly transferred to the outside of the high-speed rail car through the doors and windows made of aluminum alloy profiles, causing the temperature inside the high-speed rail car to drop sharply, which brings discomfort to the people in the high-speed rail car, and people have to use heating for heating; and in the hot sum...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing aluminum alloy profiles for middle stiles and thermal insulation bridges for high-speed railways cannot completely isolate heat, and the sound insulation effect is poor. Moreover, the strength of the aluminum profile frame is poor, variable, and the structural connection is not firm.
