Abstract
The utility model discloses an equipment body throttling device for improving the defrosting and demisting performance of a front windshield of a passenger car, which is characterized in that through the connection optimization between the equipment body throttling device and a passenger car instrument desk, when the defroster device is connected with an instrument desk air outlet, a round adjustable air outlet on the instrument desk is connected to correspond to the air outlet position on the defroster body, and the equipment body throttling device is installed; the wind speed of the long air outlet is obviously improved when the regulation proportion is 50 percent; when the front windshield needs defrosting and demisting, the best effect can be achieved within standard time. The utility model has simple structure, and only needs to add a throttling device of the equipment body at the position of a respective air outlet on the defroster device; the problem that the air speed of the long air outlet of the instrument desk is low can be effectively solved; the device is simple to operate and convenient to manufacture.
Description
Technical Field
The utility model relates to a passenger train defrosting defogging equipment application technology field specifically is an improve equipment organism throttling arrangement of passenger train front windshield defrosting defogging performance.
Background
In the current passenger train market, defroster device of installation in the instrument desk inner space is mostly adopted in front windshield's defrosting defogging design, and passenger train instrument desk inner structure is complicated, and except loaded down with trivial details electric wire, windscreen wiper mechanism also installs this region, other electrical equipment in addition. The passenger car has various models and structures, and CFD analysis is basically in the blank; passenger car factories generally adopt the following two methods for treatment, namely: the instrument desk is provided with a cavity, two 120mm connecting pipe spigots are reserved at the installation position of the defroster, and the defroster device is connected through a telescopic hose; the second method comprises the following steps: each air outlet on the instrument desk is provided with a connecting pipe spigot, and is respectively connected with an air outlet on the defroster device through a telescopic hose; the instrument desk mostly adopts a strip-shaped air outlet, and the left corner, the right corner and the pedal position of a driver mostly adopt round adjustable air outlets; fans of the defroster are both double-volute centrifugal fans, and the air outlets of the fans are two rectangular outlets and are converted into circular interfaces with different numbers through interfaces of the shell of the defroster.
Adopt the mode that the wind chamber was made to the instrument desk, the problem that appears does: a plurality of small vortexes, turbulence and turbulent flow phenomena exist in a flow field in the air cavity, and the flow of the air is not smooth; the wind speed distribution of the air outlet of the instrument desk is uneven, and the requirement of 5-8m/s of the wind speed of the air outlet required by the national standard is difficult to achieve;
adopt the mode that every air outlet respectively takes over the tang on the instrument desk, the problem that appears is: the difference between the wind speed of the long strip air outlet of the instrument desk and the wind speed of the round adjustable air outlet is large, and the wind speed and the wind quantity of the round adjustable air outlet are far larger than those of the strip air outlet because the strip air outlet is smaller than the wind resistance of the round adjustable air outlet in a structural mode, so that the defrosting of the front windshield area corresponding to the strip air outlet is realized, and the defogging performance is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem, provide an improve equipment organism throttling arrangement of passenger train front windshield defrosting defogging performance, the utility model discloses used technical scheme is:
a device body throttling device for improving defrosting and demisting performances of a front air damper of a passenger car comprises an instrument desk, a strip-shaped air outlet, a defroster, a device body throttling device, an induced duct and a round adjustable air outlet; the defroster is respectively connected with a strip-shaped air outlet and a round adjustable air outlet on the instrument desk through an induced duct; the throttling device of the equipment body is arranged at the air outlet position on the defroster body corresponding to the round adjustable air outlet.
The opening degree of the round adjustable air outlet is 50%.
The beneficial effects of the utility model reside in that:
the utility model has simple structure, and only needs to add a throttling device of the equipment body at the position of a respective air outlet on the defroster device; the problem that the defrosting and demisting effects of the defroster are poor due to the fact that the air speed of the long strip air outlet of the instrument desk is small can be effectively solved; the device is simple to operate and convenient to manufacture.
Drawings
Fig. 1 is the utility model relates to an improve equipment organism throttling arrangement schematic diagram of passenger train front windshield defrosting defogging performance.
In the figure: 1. an instrument desk; 2. a strip-shaped air outlet; 3. a defroster; 4. a device body throttling device; 5. an induced draft pipe; 6. circular adjustable air outlet.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Example (b): see fig. 1.
A device body throttling device for improving defrosting and demisting performances of a front air damper of a passenger car comprises an instrument desk 1, a strip-shaped air outlet 2, a defroster 3, a device body throttling device 4, an induced duct 5 and a round adjustable air outlet 6; the defroster 3 is respectively connected with a strip-shaped air outlet 2 and a round adjustable air outlet 6 on the instrument desk 1 through an induced duct 5; the equipment body throttling device 4 is arranged at the air outlet position on the defroster 3 body corresponding to the round adjustable air outlet 6.
The opening degree of the round adjustable air outlet 6 is 50%.
The utility model discloses the theory of operation of device does: when the defroster 3 device is connected with the air outlet of the instrument desk 1, the air outlet position on the defroster 3 machine body corresponding to the round adjustable air outlet 6 on the instrument desk 1 is connected, and the equipment machine body throttling device 4 is installed; the wind speed of the long strip-shaped air outlet 2 is obviously improved when the proportion is adjusted to be 50%; the front windshield can achieve the best defrosting and demisting effects within standard time.
Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can be modified or replaced with other embodiments without departing from the spirit and scope of the present invention, and all such modifications and equivalent substitutions are intended to be encompassed by the scope of the following claims.
