Abstract
The utility model relates to a low-vibration and low-noise track passenger train overhead embedded type air conditioning unit which comprises a machine set bottom plate, wherein, a piece of sound-absorption and thermal-insulation cotton is stuck under the machine set bottom plate, the outer layer of the sound-absorption and thermal-insulation cotton is enclosed by a protective board and a damping vibration-absorbing sheet is arranged on the inner side of the protective board. The utility model solves the problem that air conditioning unit for the track passenger train configured with an overhead embedded type air conditioning unit at present generates larger-noise pollution to the carriage during the running process, and affects the comfort level of riding of the passengers; and after being configured on the track passenger train, the overhead embedded type air conditioning unit is low in vibration and noise during the running and further ensures the comfort level index of riding.
Description
Technical field
The utility model relates to a kind of track passenger train overhead embedded type air conditioner unit of the low low noise that shakes.
Background technology
Along with the development of society, the progress of science and technology, the effect of track traffic (railroad train, subway etc.) in current communications and transportation is more and more big.In the track passenger train,, in railway car, all dispose air-conditioning in order to improve the comfortableness that the passenger rides.Present high-speed track passenger train, because its travel speed very fast (generally all more than 200km/h), when the configuration air-conditioning, consider traveling security and air-conditioning unit traveling comfort, adopted overhead embedded type air conditioner unit, be that the air-conditioning unit embeds the compartment at compartment overhead and unit Lower Half, so both be beneficial to the reduction of car load center of gravity, the external wind pressure that produces in the time of also can reducing the vehicle high-speed cruising.But the air-conditioning unit inevitably has operating noise when operation, and Embedded installation will strengthen it to the noise pollution in the compartment.For the comfortableness that guarantees that the passenger rides, just must carry out sound insulation, vibration damping etc. and improve design the Embedded air-conditioning unit of overhead.
The utility model content
The technical problems to be solved in the utility model is: the track passenger train overhead embedded type air conditioner unit that a kind of low low noise that shakes is provided, with solve be equipped with overhead embedded type air conditioner unit at present its air-conditioning unit of track passenger train in running to producing big noise pollution in the compartment, influence the problem of passenger's ride quality.
The technical solution adopted in the utility model is: a kind of track passenger train overhead embedded type air conditioner unit of the low low noise that shakes, has the unit base plate, sticking under the unit base plate has the sound-absorption and heat-insulation cotton, and be coated with the stainless steel protective plate at its skin, be provided with the damping vibration attenuation sheet at the inner face of stainless steel protective plate.Cotton its material of described sound-absorption and heat-insulation is a perforate melamine resin condensate.Its material of described protective plate is a stainless steel.Described damping vibration attenuation sheet is covered to be pressed on the pitch condensate by the ripple aluminium flake and forms.
The beneficial effects of the utility model are: solved be equipped with overhead embedded type air conditioner unit at present its air-conditioning unit of track passenger train in running to producing big noise pollution in the compartment, influence the problem of passenger's ride quality.Overhead embedded type air conditioner configuration set of the present utility model is after on the passenger train, and the low low noise that shakes has guaranteed the comfort level index of taking during operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
The structural representation of the sound insulation vibration absorber that the effect of Fig. 1 low low noise that shakes that is air-conditioning unit of the present utility model when reaching operation is provided with in its unit floor below.
The specific embodiment
The structural representation of the sound insulation vibration absorber that the effect of Fig. 1 low low noise that shakes that is this air-conditioning unit when reaching operation is provided with in its unit floor below, sticking for 1 time at the unit base plate has sound-absorption and heat-insulation cotton 2, and be coated with stainless steel protective plate 3 at its skin, be provided with damping vibration attenuation sheet 4 at the inner face of stainless steel protective plate 3; Cotton 2 its materials of described sound-absorption and heat-insulation are perforate melamine resin condensate; Described damping vibration attenuation sheet 4 is covered to be pressed on the pitch condensate by the ripple aluminium flake and forms.
Sound insulation vibration absorber with complex sound insulation vibration-proof structure, one side has weakened the operating noise of the air-conditioning unit that imports in the compartment, has weakened the vibration of air-conditioning unit body on the one hand again by damping, has reduced the generation of noise.
