A kind of spiral case of coiler, including spiral case body；Wind wheel is provided with the spiral case body；Baffle liner is provided with the side wall of the spiral case body both sides；Air outlet is provided with the spiral case body, it is characterised in that：The sidewall slope of the spiral case body both sides is set；Radius length in the baffle liner is uneven；The surface of the spiral case body is provided with spiral case button bit；The spiral case body bottom portion both sides are set for fillet.In the utility model, spiral case side wall is made into inclined plane, rather than traditional vertical plane, is conducive to increase incoming air area, improves the air quantity of system.Because the water conservancy diversion of sloped sidewall, air-flow can scatter after spiral case comes out to both sides, and air-flow can relatively evenly blow to evaporator surface, can lift the heat exchange efficiency of evaporator, reduce the impact of primary air and evaporator, be conducive to the decline of noise.
Description
Technical field
A kind of spiral case is the utility model is related to, is specifically a kind of spiral case of coiler.
Background technology
Existing coiler spiral case, its spiral case wall use vertical plane, cause incoming air area limited；Spiral case baffle liner due to
The limitation of body structure, the intake and intake velocity of the left and right sides are different, close to complete machine air inlet side air quantity and wind
Speed can be some larger, influences the fluency of inlet air air-flow.Among traditional Volute Design, button bit is located at baffle liner both sides, because
Charge air flow is hindered for its shape, is unfavorable for the lifting of air quantity.
A kind of Horizontal type concealed fan unit as disclosed in Chinese patent literature CN203147917U in August in 2013 21 days
Pipe, belongs to ceiling type fan coil, including upper cover plate, side plate, volute of blower, surface cooler, condensation water pond, water collection sheet, air outlet
Be L-square Deng, the air outlet and upper cover plate junction, i.e., the surface plate of upper cover plate connects skewback, and skewback connects right angle
Plate, L-square connect the facet plate of air outlet, and the L-square is vertical with the facet plate of air outlet.The patent just has upper
State defect.
Therefore, it is necessary to further improve.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, significant effect, lifts air quantity, reduces noise,
Ensure the spiral case of the coiler of stable inlet air, to overcome shortcoming of the prior art.
By a kind of spiral case of coiler of this purpose design, including spiral case body；Wind is provided with the spiral case body
Wheel；Baffle liner is provided with the side wall of the spiral case body both sides；Complete machine air inlet is provided with the spiral case body and is gone out
Air port, it is characterised in that：The sidewall slope of the spiral case both sides is set；Radius length in the baffle liner is uneven；It is described
The surface of spiral case is provided with spiral case button bit；The spiral case two bottom sides are set for fillet.
Radius of the baffle liner close to complete machine air inlet side is R2, the radius R1 close to air outlet side；R1>R2.
The end face of the nearly wind wheel one end of the baffle liner and wind wheel are arranged in parallel.
The spiral case button bit is located at the adjacent position of complete machine air inlet and air outlet, and side is provided with least two
Spiral case button bit.
The longer seamed edge of the spiral case two bottom sides is that fillet is set.
In the utility model, spiral case side wall is made into inclined plane, rather than traditional vertical plane, is conducive to increase air intake surface
Product, improves the air quantity of system.Because the water conservancy diversion of sloped sidewall, air-flow can scatter after spiral case comes out to both sides, and air-flow can be compared with
Evaporator surface is equably blown to, the heat exchange efficiency of evaporator can be lifted, the impact of primary air and evaporator is reduced, is conducive to
The decline of noise.Baffle liner end face and wind wheel end face keeping parallelism, prevent air-flow from, from the leakage rate at baffle liner, ensureing inlet air
Stability.Baffle liner is different close to the radius of air outlet side and the water conservancy diversion radius of nearly air inlet side, it is ensured that air-flow
In the case of front/rear end inlet air is non-uniform, the fluency of inlet air air-flow.Spiral case button bit be designed to it is front and rear be positioned over complete machine into
At air port and air outlet, unlike traditional both sides for being arranged on baffle liner, reduce because shape and to the obstruction of charge air flow,
Be conducive to the lifting of air quantity.Spiral case corner rounding so that air-flow is more smooth during baffle liner by entering, beneficial under noise
Drop.

Embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1-Fig. 6, a kind of spiral case of coiler, including spiral case body 1；Wind wheel 2 is provided with spiral case body 1；Snail
Baffle liner 1.2 is provided with the side wall 1.1 of 1 both sides of shell body；Air outlet 1.3,1 liang of spiral case body are provided with spiral case body 1
The side wall 1.1 of side is obliquely installed；Radius length in baffle liner 1.2 is uneven；The surface of spiral case body 1 is provided with spiral case button bit
1.4；1 two bottom sides of spiral case body are set for fillet.
Further, radius of the baffle liner 1.2 close to complete machine air inlet side is R2, close to 1.3 side of air outlet
Radius R1；R1>R2.
Further, the end face of nearly 2 one end of wind wheel of baffle liner 1.2 and wind wheel 2 are arranged in parallel.
Further, spiral case button bit 1.4 is respectively positioned at the adjacent position of complete machine air inlet and air outlet 1.3, and often
Side is provided with least two.
Further, the longer seamed edge of 1 two bottom sides of spiral case body is that fillet is set.
Concrete operating principle：The seamed edge fillet of spiral case bottom, can lift fluency when air-flow passes through spiral case, effectively carry
Rise air quantity.Spiral case button bit is accomplished before and after spiral case at nearly air port and air outlet, not accomplishing traditional baffle liner or so two
On side, reduce the obstruction flowed because of shape to charge air flow, be conducive to the lifting of air quantity.
Spiral case wall makes inclined plane, between increase spiral case and the metallic plate of the left and right sides, spiral case and spiral case
Gap, effectively lifts air quantity.Referring to Fig. 2, because the guide functions of spiral case inclined wall, air-flow is after volute outlet comes out, meeting
Scatter to both sides, what air-flow can be more uniformly distributed blows to evaporator surface, on the one hand can lift the heat exchange efficiency of evaporator, another
Aspect can reduce the impact of primary air and evaporator, be conducive to the decline of noise.
Referring to Fig. 3, because the limitation of body structure, the intake and intake velocity of the left and right sides are different, close to whole
Machine air inlet side air quantity can be some larger with wind speed, therefore the different RI of baffle liner water conservancy diversion radius of the left and right sides>R2, it is more sharp
Enter the fluency of baffle liner in air-flow, beneficial to the decline of noise.Baffle liner end face and wind wheel end face keeping parallelism at the same time, prevent
Air-flow ensures the stability of inlet air from the leakage rate at baffle liner.
Test result indicates that：Using new construction spiral case, inlet air and the fluency of outlet air are optimized so that complete machine noise performance
It has a certain upgrade, can declines 2.5db with level of noise under air quantity.
It is as shown in the table：
The above-mentioned preferred solution for the utility model, has been shown and described the basic principle, main feature of the utility model
And the advantages of the utility model.Those skilled in the art should be recognized that the present utility model is not limited to the above embodiments, on
