Abstract
The utility model relates to a kind of screw type wavelength tube, be arranged on automotive air intake pipe, it is characterized in that, described screw type wavelength tube comprises two wavelength semicanals, each wavelength semicanal comprises outer wall and is arranged on the spiral salient of recess in outer wall, the spiral salient part engagement of two wavelength semicanal inside, and after two wavelength semicanal engagements, outer wall and spiral salient form screw type wavelength tube cavity.Compared with prior art, the utility model has spaces compact, advantages of simple structure and simple.
Description
Technical field
The utility model relates to a kind of wavelength tube, especially relates to a kind of screw type wavelength tube.
Background technique
At present, the induction noise of motor is by vast automobile vendor is paid attention to, increasing muffler appears at above the pipeline of gas handling system, but the compactedness due to engine compartment requires also day by day to increase, and the existing layout scope being integrated in resonator on pipeline gradually can not meet now compact cabin design and require that.
Application number be 201320462388.8 Chinese patent disclose a kind of frequency-adjustable 1/4 wavelength tube, this wavelength tube is vertical with intake duct to be arranged, and institute takes up space comparatively large, can not meet the requirement in compact cabin.
Model utility content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and provide a kind of spaces compact, structure simple screw type wavelength tube.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of screw type wavelength tube, be arranged on automotive air intake pipe, it is characterized in that, described screw type wavelength tube comprises two wavelength semicanals, each wavelength semicanal comprises outer wall and is arranged on the spiral salient of recess in outer wall, the spiral salient part engagement of two wavelength semicanal inside, and after two wavelength semicanal engagements, outer wall and spiral salient form screw type wavelength tube cavity.
Two described wavelength semicanals are by the mutual clamping of the buckle on outer wall.
The channel cross-section of described screw type wavelength tube cavity is circular or oval.
The centerline length of described screw type wavelength tube is 1/4th wave length of sounds.
The making material of described wavelength semicanal is plastics.
Compared with prior art, the utility model has the following advantages:
One, spaces compact, the present invention adopts the wavelength tube of spiral form to replace the wavelength tube of straighttube-type, and screw type wavelength tube can be close to suction tude, compact structure, saves space, both artistic and practical.
Two, structure is simple, and this screw type wavelength tube is only made up of two relative wavelength semicanals, and structure is simple, cost is low, be easy to change.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Wherein: 1, automotive air intake pipe, 2, wavelength semicanal.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
