Problems solved by technology

[0004] Based on this, it is necessary to focus on the high thermal conductivity of the aluminum alloy profiles of the car body envelope and the large temperature difference between the inside and outside of the aluminum alloy profile cavity, which leads to natural convection in the cavity, which makes the heat transfer efficiency in the cavity intense increase, resulting in a large overall heat loss of the car body enclosure structure, to provide an aluminum alloy profile structure that can effectively reduce the heat transfer efficiency in the cavity of the aluminum alloy profile to improve the overall heat insulation performance of the car body envelope structure and the vehicle body envelope

Embodiment Construction

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom", "top" and similar expressions...

Abstract

The invention relates to an aluminum alloy profile structure and a vehicle body enclosure structure. The vehicle body enclosure structure comprises the aluminum alloy profile structure which comprisesa body and heat insulation bodies. The body comprises a first face layer and a second face layer which are oppositely arranged, a plurality of rib strips are arranged between the first face layer andthe second face layer at intervals, cavities are formed among every two adjacent rib strips and the first face layer as well as every two adjacent rib strips and the second face layer, and the cavities are provided with the opening ends. The heat insulation bodies are arranged on the inner side walls of the cavities. According to the aluminum alloy profile structure and the vehicle body enclosurestructure, the heat exchanging efficiency in the aluminum alloy profile cavities can be effectively lowered so that the overall heat insulation performance of the vehicle body enclosure structure canbe improved, and power consumption of vehicle body air conditioner system operation is reduced accordingly.

Description

technical field [0001] The invention relates to an aluminum alloy profile structure and a car body enclosure structure. Background technique [0002] With the continuous extension of the mileage and scope of high-speed rail, the vehicle manufacturing field has higher and higher requirements for the comprehensive heat insulation performance of the vehicle body. Among them, under the condition that the profile material, strength and weight of the car body remain unchanged, the heat insulation performance of the car body is significantly improved, which becomes the key to energy saving of the car body air conditioning system. At present, most of the car bodies are made of aluminum alloy profiles. Due to the high thermal conductivity of the aluminum alloy material itself, and the large temperature difference between the inside and outside of the aluminum alloy profile cavity, natural convection occurs in the cavity. Under natural convection conditions , the heat exchange effici...
