Background technique
Currently, being mainly made of stator, rotor, shell and end cap, with extensively in electricity in engineering machinery in motor
When machine works, a large amount of heat can be generated, when the excessive motor of heat will appear failure, is stopped working, it is serious to puncture,
Lead to motor burning, heat sink strip can be circumferentially arranged in existing motor housing, increase heat dissipation area, but the diameter of movement passes through
Two sides of heat sink strip are radiated, and heat sink strip is mutually indepedent, not can be carried out and mutually compensates cooperation, and heat dissipation capacity has
Limit, also has and opens up air vent on shell, accelerates heat exchange by air vent, so that the motor of rotor radiates, but holds
Easily external dust is sucked, so that the circulation of air is obstructed, reduces heat emission efficiency,
Publication number CN205565972U discloses a kind of high efficiency and heat radiation electric machine casing, including cylindrical shell, housing exterior walls
It is bent to form several outer radiating ribs and interior radiating ribs, outer radiating ribs and the setting of interior radiating ribs interval, outer radiating ribs respectively with inner wall
Circumferentially distributed along shell respectively with interior radiating ribs, interior radiating ribs end is also bent to form support portion, and several interior radiating ribs are corresponding
The medial surface of support portion towards shell axis form coaxial with shell and fracture setting circular ring shape, this method passes through multiple curved
Folding so that cooling fin is double-layer structure, and extends simultaneously to inside and outside simultaneously, due to the use of electric machine casing inside and outside wall, inwardly prolongs
The spacing between cooling fin stretched can reduce, so that air-flow stays amount of flow to reduce, double-deck outer cooling fin effect is poor, cannot
It is a large amount of to carry out heat exchange, influence heat dissipation effect.
Summary of the invention
In order to improve above situation, a kind of electric machine casing cooling fin of the utility model provides one kind by electric machine casing
Outside forms the device that the heat dissipation bucket of annular radiates to motor by being mutually inserted between multiple cooling fins.Structure letter
It is single, it is convenient and practical.
A kind of electric machine casing cooling fin of the utility model is realized in：A kind of electric machine casing cooling fin of the utility model
It is made of ceramic film, support seat board, main cooling fin, auxiliary cooling fin, semicircle groove and inserting groove, ceramic film is placed in support base
Board bottom portion, the support seat board is arc panel, and is extended along axial direction, and the arc round and in position of the support seat board is in bottom one
Side, main cooling fin and auxiliary cooling fin are symmetrically placed on support seat board, and the main cooling fin and auxiliary cooling fin intersecting lens are located at support
In the middle part of seat board, angle is 45 ° -60 ° between the main cooling fin and auxiliary cooling fin, and the main cooling fin top edge is equidistantly opened
Have multiple semicircle grooves, the auxiliary cooling fin top edge is equidistantly provided with multiple semicircle grooves, and with the semicircle on main cooling fin
Groove is corresponding, and main cooling fin is provided with inserting groove from the medium position at support seat board to top, and the inserting groove is along support seat board
It is axially extending, until the half position of main fin length, inserting groove, the inserting groove on the auxiliary cooling fin are provided on auxiliary cooling fin
Open a little supplemented by cooling fin one end medium position, extend to the half of auxiliary fin length, and on extending direction and main cooling fin
Inserting groove is on the contrary, the width of the inserting groove is equal to the thickness of main cooling fin.
In use, motor housing is clean, the support seat board on the first radiator is axially arranged along motor housing
Column, ceramic film and electric machine casing outer wall fit closely, then dissipate the inserting groove of cooling fin auxiliary on the second radiator and first
Inserting groove on main cooling fin on backing carries out grafting, then forms connection, and then proceeding to will be auxiliary scattered on third radiator
Backing and the second main cooling fin of fan backing carry out grafting, carry out grafting by multiple radiators, form close ring, connection is completed
Afterwards, support base board group closes to form annulus, and is bonded by ceramic film and motor housing, main cooling fin and the auxiliary cooling fin to connect
Between form channel, and be equidistantly looped around electric machine casing outer ring, the distance between two adjacent main cooling fins are along radial direction
It becomes larger, forms open architecture, when motor, which works, generates heat, a large amount of heat is transmitted to ceramic film by electric machine casing
On, ceramic film by heat by supporting seat board to be transferred to main cooling fin, on auxiliary cooling fin, due to the main cooling fin of grafting and auxiliary
The channel axially extending along electric machine casing is differed between cooling fin, air-flow is flowed out of channel carries out heat exchange, heat is taken away,
Partial heat is gradually diffused by main cooling fin, auxiliary cooling fin to external diffusion, and by open gap, in the course of work
In, since main cooling fin, auxiliary cooling fin are mutually inserted to form close ring, and connection is formed between each other, in local location temperature
When spending high, heat can be shifted by plug-in position, and other positions is enabled to carry out heat sharing, drop to high temperature dot
Concentration low in calories avoids motor hot-spot scaling loss, achievees the purpose that radiate to electric machine casing.
Beneficial effect.
One, structure is simple, convenient and practical.
Two, it can be improved the heat exchanger effectiveness of heat dissipation.
Three, the compensation that can be improved between mutual cooling fin is shared, and amount of localized heat is avoided to concentrate.
