The utility model discloses simple structure, it is with low costs, and solved foraminiferous cloth wind ware effectively along cloth wind disk track to the inhomogeneous problem of cloth wind.
Description
Technical field
The utility model relates to a kind of ventilation terminal, particularly relates to a kind of ventilation terminal with radial hole, belongs to the end equipment of ship's ventilating system.
Background technology
Ventilation terminal is the end equipment of common marine air conditioning ventilating system, airflow passes plenum chamber, through the neck directive distributing wind disc of ventilation terminal, then is sent in cabin by distributing wind disc jet, reaches and provide good indoor air quality and the object of comfort level.Distributing wind disc comprises upper and lower two pieces of air distribution plates.Common ventilation terminal is mainly divided into according to shape: side's (square) shape ventilation terminal and circular ventilation terminal.Ventilation terminal with holes and ventilation terminal not with holes can also be divided into according to whether lower air distribution plate is with holes.
Air-flow can only be sent from distributing wind disc surrounding by above-mentioned ventilation terminal not with holes, airflow direction is for attaching flat sending, therefore fresh air cannot directly arrive distributing wind disc lower zone, ventilation terminal with holes then solves this problem, fraction is sent from distributing wind disc surrounding, and under a part of airflow passes, the aperture of air distribution plate is sent downwards in addition.
Ventilation terminal with holes in the market, the size in hole is unified, and the layout in hole is even.Which results in and there are some problems in actual application: from the center of distributing wind disc to the outside of distributing wind disc, the direction of air-flow is sent by gradually becoming horizontal completely straight down, the downward speed of air-flow is successively decreased along distributing wind disc radial direction, and downward speed more air flow more easily flow through below aperture, so the air-flow sent by the aperture of distributing wind disc central area is many, the air-flow sent by the aperture of distributing wind disc exterior lateral area is few, causes along the uneven problem of the radial cloth wind of distributing wind disc.
Summary of the invention
The purpose of this utility model to provide along the uneven problem of distributing wind disc radial cloth wind that a kind of structure is simple, the ventilation terminal in the radial hole of band of economical to effectively solve ventilation terminal with holes.
The purpose of this utility model is achieved in that the ventilation terminal neck comprising lower air distribution plate, upper wind plate and be arranged on upper wind plate, lower air distribution plate is connected by spring clip with upper wind plate, and described lower air distribution plate is provided with aperture, described aperture along the circumference of lower air distribution plate be arranged in from the inside to the outside two-layer more than aperture circle, and in aperture circle the aperture of aperture along the radial direction of lower air distribution plate, increase successively from the inside to the outside.
The utility model also comprises some architectural features like this:
1. the aperture of the aperture in adjacent two layers aperture circle is more satisfied than α: 0 < α < 1, wherein
r
1for inner side aperture radius, r
2for the outer apertures radius adjacent with described inner side aperture.
2. the Distances Between Neighboring Edge Points β between adjacent two layers aperture circle meets: β > 0, wherein β=R
2-R
1-(r
1+ r
2), R
1for the distance between the center of inner side aperture and the center of lower air distribution plate, R
2for the distance between the center of the adjacent outer apertures of inner side aperture and the center of lower air distribution plate.
Compared with prior art, the beneficial effects of the utility model are: the small pitch inside lower air distribution plate is close to air distribution plate center, and air-flow has larger speed straight down, but due to aperture little, therefore resistance is comparatively large, makes to be unlikely to excessive by the aperture flow of inner side.Small pitch outside lower air distribution plate is close to air distribution plate center, and air-flow speed is straight down very little, but due to aperture comparatively large, therefore resistance is less, makes to be unlikely to too small by the aperture flow in outside.By considering airflow direction and aperture resistance to the impact of cloth wind, flowing out from each aperture with making uniform stream, efficiently solving ventilation terminal with holes along the uneven problem of the radial cloth wind of distributing wind disc.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
The technical solution adopted in the utility model is: a kind of ventilation terminal with radial hole, comprises lower air distribution plate, upper wind plate, spring clip and ventilation terminal neck.Spring clip connects upper wind plate and lower air distribution plate, and air-flow sends into air distribution plate directive from neck, and lower air distribution plate has aperture, and the aperture along air distribution plate radial hole increases successively.
Aperture on above-mentioned lower air distribution plate is arranged as some layers of concentric circles from inside to outside, and the ray of being drawn by air distribution plate center is from inside to outside successively through the central point of each layer aperture.
Aperture on above-mentioned lower air distribution plate is arranged in order from inside to outside, if inner side aperture radius is r
1, adjacent outer aperture radius is r
2, definition
α represents the ratio in adjacent apertures aperture, has 0 < α < 1.
Aperture on above-mentioned lower air distribution plate is arranged in order from inside to outside, if inner side small hole center and lower air distribution plate centre distance are R
1, adjacent outer small hole center and lower air distribution plate centre distance are R
2, definition β=R
2-R
1-(r
1+ r
2), β represents adjacent two layers aperture edge spacing, has β > 0.
As shown in Figure 1, aperture with radial distribution on lower air distribution plate 1, upper wind plate 2 and lower air distribution plate 1 are linked by spring clip 4, and both are circle, and diameter is 335mm, aperture is circular, wherein ratio α=0.75 in adjacent apertures aperture, adjacent two layers aperture edge spacing β=5mm, inner side small aperture is 5mm, every layer of aperture is 22, and neck 3 diameter is 140mm.Fig. 2 and Fig. 3 is respectively assembly drawing and the aperture distribution map of band radial hole ventilation terminal.
In order to verify the air-supply effect with radial hole ventilation terminal in this embodiment, carried out numerical simulation respectively to band radial hole ventilation terminal and conventional uniform cloth hole ventilation terminal, Fig. 4, Fig. 5 and Fig. 6 are respectively the STRUCTURE DECOMPOSITION figure of contrasted conventional uniform cloth hole ventilation terminal, assembly drawing and aperture distribution map.Take air output as 300m
3/ h is example, and analog result as shown in Figure 7.
The abscissa of Fig. 7 is the distance at distance air distribution plate center in X direction, ordinate is downward velocity amplitude, can clearly be seen that from Fig. 7, along air distribution plate radial direction, the difference of speed downward between each aperture of conventional uniform cloth hole ventilation terminal reaches about 2.5m/s, difference with speed downward between each aperture of radial hole ventilation terminal controls within 0.8m/s, and visible band radial hole ventilation terminal greatly strengthen the uniformity of cloth wind.
