Abstract
The utility model discloses the air distributor of an air cooler, which comprises an air inlet and an air outlet. The air outlet is connected with the air cooler. A horn-shaped passage, which is gradually widened from the air inlet to the air outlet, is provided with orifice plates. At least two layers of orifice plates are arranged. The diameters of circular holes on each layer of orifice plate are orderly reduced from the air inlet to the air outlet. According to the technical scheme of the utility model, due to the adoption of the plurality of layers of orifice plates, the air entering the horn-shaped passage is distributed. Therefore, the phenomenon that the flow rate of air at the middle part of the horn-shaped passage is larger than the flow rate of air at the peripheral part around the horn-shaped passage, can be avoided. In this way, the air can be uniformly distributed before entering the air cooler. The air distributor of the air cooler has the advantages of simple structure, convenient implementation and low manufacturing cost, and effectively improves the efficiency of the air distribution and conveying.
Description
Technical field
The utility model relates to a kind of air distributor, is specifically related to a kind of air cooler air distributor.
Background technology
In fields such as petroleum chemical engineerings, often run into the inhomogeneous problem of air-distribution that enters air cooler.Air also belongs to fluid, when entering loudspeaker door, due to the problem of friction and inertia, often center flow velocity is higher than the flow velocity of ambient air, cause the distribution serious unbalance of air, affected the air cooling effect of air cooler, even affect normal operation and the service life of equipment.
Utility model content
The purpose of this utility model is for a kind of air cooler air distributor is provided, and enters the technical problem of the air maldistribution of air cooler to solve prior art.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of air cooler air distributor, comprise air intake and air outlet slit, described air outlet slit is connected with air cooler, from air intake to air outlet slit, gradually on wide tapering trumpet-like passage, be provided with orifice plate, described orifice plate is at least two-layer.
On described every layer of orifice plate, the direction of the diameter of circular hole along air intake to air outlet slit reduces successively.
Described orifice plate is circular.
The relative prior art of the utility model has following beneficial effect: the utility model distributes by multilayer orifice plate is set the air that enters tapering trumpet-like passage, solved tapering trumpet-like passage core air stream speed and be greater than the phenomenon of ambient air flow velocity, thereby made air before entering air cooler, reach uniform distribution.The utility model is simple in structure, enforcement is convenient, cost of manufacture is low, has effectively improved and has distributed the efficiency of carrying air.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral implication is as follows: 1, air cooler; 2, passage; 3, orifice plate; 4, circular hole; 5, air intake; 6, air outlet slit.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of air cooler air distributor, comprise air intake 5 and air outlet slit 6, air outlet slit 6 is connected with air cooler 1, from air intake 5 to air outlet slit 6 gradually wide tapering trumpet-like passage 2 be provided with orifice plate 3, orifice plate 3 is at least two-layer, orifice plate 3 is disk and thin plate, on every layer of orifice plate 3, circular hole 4 varies in size, and on every layer of orifice plate 3, the direction of the diameter of circular hole 4 along air intake 5 to air outlet slit 6 reduces successively, diameter the closer to the circular hole 4 on the orifice plate 3 of air intake 5 is larger, up reduce successively, the number of plies of orifice plate 3, on orifice plate 3, the size of circular hole 4 is determined according to the specification of air cooler 1.
During use, air enters tapering trumpet-like passage 2 from air intake 5, air is by being arranged on the orifice plate 3 with circular hole 4 on tapering trumpet-like passage 2, because the diameter of the circular hole 4 on the orifice plate 3 the closer to air intake 5 is larger, up reduce successively, air had reached uniform distribution before entering air cooler 1.
Claims (3)
1. an air cooler air distributor, comprise air intake (5) and air outlet slit (6), described air outlet slit (6) is connected with air cooler (1), it is characterized in that: from air intake (5) to air outlet slit (6) gradually wide tapering trumpet-like passage (2) be provided with orifice plate (3), described orifice plate (3) is at least two-layer.
2. a kind of air cooler air distributor according to claim 1, is characterized in that: the direction of the diameter of the upper circular hole (4) of described every layer of orifice plate (3) along air intake (5) to air outlet slit (6) reduces successively.
