Abstract
The utility model discloses a noise reduction air handling unit which comprises an air handling unit body. Flow passages which are formed by separation of a flow passage wall and are used for air flow to flow through are formed in the air handling unit body; both sides of the flow passage wall are provided with the flow passages; the flow passage wall is provided with a positioning pillar; the positioning pillar is arranged on the lateral surface of the flow passage wall, which faces the low-flow-rate flow passage; the lateral surface of the flow passage wall, which faces the high-flow-rate flow passage, is smooth and flat. According to the noise reduction air handling unit disclosed by the utility model, by arranging the positioning pillar at one side of the flow passage wall, which faces the low-flow-rate flow passage and arranging the lateral surface of the flow passage wall, which faces the high-flow-rate flow passage, into the smooth and flat lateral surface, high-speed air flow can be effectively prevented from being stopped in the flowing process, so that noise and pressure loss can be reduced.
Description
Technical field
The utility model relates to a kind of air-conditioning box, and concrete is a kind of air-conditioning box with noise reduction.
Background technology
As shown in Figure 1, be the structural representation of existing a kind of air-conditioning box.In this air-conditioning box, be provided with the runner 2 for circulation of air, flow path wall 4 is provided with locating dowel 3.Because erection column 3 need to take larger space, therefore be provided with projection corresponding to locating dowel on flow path wall, under the effect of high velocity air, the projection on flow path wall can cause and stops and disturb air-flow, not only cause the pressure loss of air-flow, and can cause the generation of noise.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of noise reduction air conditioner case, and this noise reduction air conditioner case can effectively reduce noise, reduce crushing.
For achieving the above object, the utility model provides following technical scheme:
A kind of noise reduction air conditioner case, comprise air-conditioning box body, in described air-conditioning box body, be provided with by flow path wall and be separated to form and for the runner of airflow, the both sides of described flow path wall are equipped with runner, described flow path wall is provided with locating dowel, described locating dowel is arranged on described flow path wall on the side of low flow velocity runner, and described flow path wall is smooth towards the smooth-sided compression candles of high flow rate runner.
Further, described flow path wall is provided with thickening projection towards the side of low flow velocity runner, and described locating dowel is arranged in described thickening projection.
Further, the protruding outer rim of described thickening is curved.
Further, the external diameter of described locating dowel is 5mm, and the outer rim external diameter of described thickening projection is 8mm.
Further, described locating dowel and described flow path wall are tangent towards the side of low flow velocity runner.
The beneficial effects of the utility model are:
Noise reduction air conditioner case of the present utility model, by locating dowel being arranged on to flow path wall towards a side of low flow velocity runner, and flow path wall is set to smooth towards the side of high flow rate runner, can effectively avoid high velocity air to be blocked in flow process, and then can reduce noise and reduce crushing.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is existing air-conditioning box structural representation;
Fig. 2 is the structural representation of noise reduction air conditioner case embodiment of the present utility model;
Fig. 3 is the A detail drawing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 2, be the structural representation of noise reduction air conditioner case embodiment of the present utility model.The noise reduction air conditioner case of the present embodiment, comprises air-conditioning box body 1, is provided with by flow path wall 4 and is separated to form and for the runner 2 of airflow, the both sides of described flow path wall 4 are equipped with runner 2 in described air-conditioning box body 1.Described flow path wall 4 is provided with locating dowel 3, and described locating dowel 3 is arranged on described flow path wall 4 on the side of low flow velocity runner 2a, and described flow path wall 4 is smooth towards the smooth-sided compression candles of high flow rate runner 2b.
In order to guarantee that locating dowel 3 has enough spaces, at flow path wall 4, on the side of low flow velocity runner 2a, be provided with thickening projection 5, described locating dowel 3 is arranged in described thickening projection 5.The outer rim of the thickening projection 5 of the present embodiment is curved, is convenient to make.By thickening projection 5 is set, can effectively guarantee that locating dowel 3 has enough space sizes and enough intensity.Concrete, the external diameter of the described locating dowel 3 of the present embodiment is 5mm, the outer rim external diameter of described thickening projection 5 is 8mm, can guarantee that locating dowel 3 and flow path wall 4 have enough intensity.
Further, described locating dowel 3 is tangent towards the side of low flow velocity runner 2a with described flow path wall 4, make the setting of locating dowel 3 can not destroy the overall structure of flow path wall 4, not only can guarantee the intensity of whole air-conditioning box, and make flow path wall 4 can arrange smoothly towards the side of high flow rate runner 2b
The noise reduction air conditioner case of the present embodiment, by locating dowel 3 being arranged on to flow path wall 4 towards a side of low flow velocity runner 2a, and flow path wall 4 is set to smooth towards the sidewall of high flow rate runner 2b, can effectively avoid high velocity air to be blocked in flow process, and then can reduce noise and reduce crushing.
Finally explanation is, above preferred embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can to it, make various changes in the form and details, and not depart from the utility model claims limited range.
