Embodiment 1

[0030] In this embodiment, the first sealing assembly includes a first annular sealing flange 1 arranged at the outer edge of the tuyere and a first sealing rubber strip 2 arranged in the annular groove of the first annular sealing flange 1 . Through the installation of the air-conditioning unit and the top of the compartment, the first sealing rubber strip 2 is closely attached to the top of the compartment to achieve sealing.

[0031] See attached Image 6 , the above-mentioned first annular sealing flange 1 is formed by a bending process, which saves the mold opening cost of the mold, and is also conducive to the modification of the design scheme. The bent annular groove facilitates the installation of the sealing strip.

Embodiment 2

[0033] Different from Embodiment 1, the first seal between the air outlet and the roof of the compartment can be realized through the first sealing assembly. Further, a second sealing assembly forming a second seal is also provided between the top of the compartment and the above-mentioned tuyere. The second sealing assembly includes a second annular sealing flange 3 arranged on the top of the compartment and a second annular sealing flange arranged on the second annular sealing flange. The second sealing strip 4 in the annular groove of 3.

[0034] The second annular sealing flange 3 is the same as the first annular sealing flange 1 and is formed by bending process, the difference lies in the height and size of the inner and outer edges.

[0035] The height of the inner annular edge of the above-mentioned first annular sealing flange 1 is greater than the height of the outer annular edge and extends into the groove of the second sealing strip 4 to compress the bottom of the g...

Abstract

The invention discloses an air-conditioning unit for EMUs, belonging to the technical field of rail vehicle air-conditioning equipment, comprising an air-conditioning unit body, characterized in that a first A sealing assembly, the first sealing assembly includes a first annular sealing flange disposed at the outer edge of the tuyere and a first sealing rubber strip disposed in an annular groove of the first annular sealing flange. The beneficial effects of the present invention are: 1. The sealing flange at the tuyere and the compartment adopts a bent sheet metal part, which replaces the existing profile while ensuring the sealing effect, avoids the cost of mold opening, and is beneficial to modify the design scheme at the same time , significantly reducing design costs and product costs. 2. The double-layer sealing structure is adopted between the tuyere and the compartment, and the double-layer sealing structure is also a labyrinth seal to ensure the airtightness of each tuyere position, and the airtightness of the unit is realized through the pressure wave protection valve arranged inside the unit .

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment for rail vehicles, and in particular relates to an air-conditioning system for EMUs. Background technique [0002] EMUs are also known as Multiple Units (MU for short), and electric multiple units are called EMUs. my country's current CRH1, CRH2, CRH3, CRH5 and my country's independent intellectual property standard EMUs are all high-speed EMUs, with a maximum operating speed of 380km / h, and CRH6 at 160-250km / h. [0003] Due to the high speed of the EMU high-speed EMU, the air-conditioning unit needs to meet the requirements of light weight and good air tightness. Most of the EMU air-conditioning units adopt the aluminum alloy structure box and adopt the embedded installation method. Through the unit The surrounding mounting flanges are connected with the vehicle body. [0004] At least the following technical problems exist in the prior art: [0005] The existing sealing fla...
