Description
Technical field:
The present invention relates to a kind of for the straight spiral case component for driving centrifugal fan of high speed electricity.
Background technique:
The straight centrifugal fan that drives of high speed electricity by rotor length dimension due to being limited, spiral case and the big multi-pass of motor casing
It crosses and is bolted, high temperature and high pressure gas when fan operation is discharged after spiral case is collected by exhaust outlet.The partial heat energy of spiral case is logical
The contact site with motor casing is crossed, motor casing is constantly passed to, motor temperature is caused persistently to increase, not to motor stabilizing operation
Benefit.
Summary of the invention:
The present invention is to provide one kind in order to solve the above-mentioned problems of the prior art and directly expel core type for high speed electricity
The spiral case component of blower.
The technical solution adopted in the present invention has: it is a kind of for the straight spiral case component for driving centrifugal fan of high speed electricity, including
Spiral case and motor casing, the spiral case are equipped with air inlet and exhaust outlet, and the bottom surface of spiral case is planar structure, the upper end of motor casing
Mouth extends outwardly and is formed the mounting plane of platform-like, and the bottom surface of spiral case and the mounting plane of motor casing are bolted company
Connect, the bottom surface of the spiral case is equipped with several kidney slots, kidney slot along air inlet circumferential directions, in the installation
Plane is equipped with round lug boss, and lug boss and motor casing are coaxially disposed, and mounting plane is separated into indent concave portion by lug boss
With outer recessed portion, it is evenly distributed with several fastening protrusions on outer recessed portion, is formed with radiating groove, spiral case between adjacent two fastening protrusion
After being fixedly connected with motor casing, recessed portion and a radiating groove are connected by a kidney slot correspondence.
Further, the bottom surface of the spiral case is equipped with several bolts hole, bolt hole and kidney slot interlaced arrangement.
Further, the fastening protrusion is equipped with through-hole, and bolt passes through through-hole and is threaded on bolt hole.
The invention has the following beneficial effects: the present invention by the contact area of reduction spiral case and motor casing, to reduce
It is directly passed to the heat of motor casing by spiral case, enhances the stability of motor operation；Invention increases spiral case wall thickness point
The uniformity of cloth improves the craftsmanship of spiral case casting.
Detailed description of the invention:
Fig. 1 is assembly structure figure of the present invention.
Fig. 2 is the partial enlarged view of spiral case and motor casing mounting surface in the present invention.
Fig. 3 is the structure chart of spiral case in the present invention.
Fig. 4 is the structure chart of motor casing in the present invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
As shown in Figure 1 to Figure 4, the present invention is a kind of for the straight spiral case component for driving centrifugal fan of high speed electricity, including spiral case 1 and electricity
Casing 2, spiral case 1 are equipped with air inlet 13 and exhaust outlet 14, and the bottom surface of spiral case 1 is planar structure, the upper port of motor casing 2 to
Outer extension and the mounting plane 20 for forming platform-like, the bottom surface of spiral case 1 and 20 company of being bolted of mounting plane of motor casing 2
It connects.
The bottom surface of spiral case 1 be equipped with several kidney slots 11, kidney slot 11 along air inlet 13 circumferential directions,
The mounting plane 20 of motor casing 2 is equipped with round lug boss 25, and lug boss 25 and motor casing 2 are coaxially disposed, and lug boss 25 will
Mounting plane 20 is separated into indent concave portion 26 and outer recessed portion 27, several uniformly distributed fastening protrusions 28, phase on outer recessed portion 27
Radiating groove 21 is formed between adjacent two fastening protrusions 28.A kidney slot after spiral case 1 is fixedly connected with motor casing 2, on spiral case 1
Recessed portion 26 in motor casing 2 is connected by 11 correspondences with a radiating groove 21.
Several bolts hole 12, bolt hole 12 and 11 interlaced arrangement of kidney slot are equipped on the bottom surface of spiral case 1.Fastening protrusion 28
It is equipped with through-hole 22, bolt passes through through-hole 22 and is threaded on bolt hole 12.
High temperature and high pressure gas when high speed electricity directly expels core type fan operation is after the air inlet 13 of spiral case 1 is collected by air draft
Mouth 14 is discharged.The present invention opens kidney slot 11 to spiral case 1 and opens radiating groove 21 to motor casing 2, to make blower at runtime, by snail
Shell 1 passes to the partial heat of motor casing 2, is transmitted in air by kidney slot 11 through radiating groove 21, without being directly passed to electricity
Casing 2, the heat that can effectively reduce motor casing 2 constantly pass to motor, motor temperature are caused constantly to rise, and it is long-term to increase motor
The stability of operation.
By excavating kidney slot 11 to spiral case 1, the Thickness Distribution of spiral case can be made more uniform, improve the casting of spiral case 1
Craftsmanship, and reduce the weight of spiral case 1 itself, reduce production cost.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
