Description
Technical field
The present invention relates to a kind of cooling device more particularly to a kind of novel Linear motor cooling devices.
Background technology
In recent years, demand is increasing in the market for linear motor, is widely used in manufacture electronic component, half
Conductor device, laser processing and finishing machine etc..It is well known that linear motor has, stability is good, speed is high and precision
The features such as high, and produce simply, there is no any contact, long lifespan, reliability height between mover and stator.Large CNC board is existing
Also linear motor replacement original design is being introduced, the power of the linear motor needed is higher and higher, this wants the performance of motor
Ask is also to be increasingly stringenter.
It is well known that the problem of linear motor is at runtime, and mover coil part can generate heat always exists, these heats are big
Part is electric current by coil, is generated due to the electricresistance effect of coil, it is directly proportional to the electric current of motor and resistance.Motor mistake
Heat will have a huge impact the runnability of motor, and coil damage can be caused even to burn other components when serious, because
This is very serious problem.
People are being dedicated to solving the heat dissipation problem of linear motor always, wherein comparing typically U.S. patent Nos
(publication number：) and Chinese patent application (application number CN201710675829.5) US8664808B2.U.S. patent Nos are (open
Number：US8664808B2 a kind of linear electric machine coil block, the serpentine rings between linear motor rotor coil and coil) are disclosed
Around cuboid aluminium block, between aluminium block water flowing achieve the effect that cool down coil, but the deficiency of the prior art is：A. original
It needs the space of unwrapping wire circle to branch away greatly to cooling device, occupies motor slot space, motor copper consumption is reduced, very greatly
The output of motor is reduced in degree；B. cooling device pipeline has many bendings inside electrical-coil, complicated；C. due to
Its complicated internal structure, production need precision high, and assembly difficulty is big, therefore produce big with assembly difficulty；D. it is filled due to cooling

It is curved around inside motor, very close with coil distance, very high to the insulation performance requirement of motor, once leak, motor is non-
Often dangerous, it is implicit that there are serious safeties.Chinese patent application (application number CN201710675829.5), it discloses a kind of straight lines
The processing method of the cooling structure of electric motor primary and linear electric motor primary, design linear motor water-cooling pattern is by having cooling
What the upper coldplate in channel and two coldplates were composed, by boiling water channel between plate to electric motor temperature reduction, but the program is still deposited
In following shortcoming:A. tetrahedron plate in side only has one side to radiate, and contact area is small, and heat-transfer effect is poor；B. it needs to multiple cold
But plate carries out complicated processing, and production technology is complicated；C. it is made of many components due to water-cooling system, each component is required for multiple
Miscellaneous processing, production and processing is of high cost, and the production cycle is long；D. because cooling device component is more, each component is required for sealing, at sealing
It is more, sealing technology very complicated, and also sealing ring can be degenerated by coolant liquid, generally require hydraulic pressure generally in 5-8Bar at present, and it is a
Other oil cooling reaches 10Bar or more, because pressure is bigger, flow is higher, and cooling effect is better, but this programme is close due to pressure is big
At envelope mostly thus poor reliability；E. this programme uses aluminum material, and aluminum material is unstable under water flowing environment, easily corrodes, and
And aluminum material thermal conductivity is bad, the thermal conductivity of aluminium sheet is only 237W/mK, far smaller than the thermal conductivity of copper；F. it is based on the above reason,
Its cooling device service life can be poor.
