Description
Technical field
The present invention relates to motor cooling technologies, and a kind of runner reverse flow double L-shaped more particularly, to axial single slot is forever
Magnetic-synchro electromotor cooling system.
Background technology
Loss can be all generated in all motor operation courses, loss not only reduces the working efficiency of motor, can also make electricity
Machine internal temperature increases.Excessively high Wen Shenghui influences the attribute of motor internal material, directly affects the safe operation of motor, especially
It is for magneto, temperature liter is excessively high to make permanent magnet that irreversible demagnetization occur.During motor use, water cooling is forever
Magnetic-synchro motor frequently with a kind of type of cooling.Permanent magnet synchronous motor is added cooling system and is mainly taken away using cooling medium
Heat is generated in permanent magnet synchronous motor operational process, plays the role of fast cooling, motor is avoided to cause to pacify because temperature is excessively high
A series of problems, such as row for the national games.
Current motor water cooling system design is mainly designed analysis to the distribution of cooling system water route, and cooling medium exists
Flow direction in cooling system is mainly along original motor axial direction Liu Dong and along motor circumferential flow.Axial water route by it is many in an axial direction
Parallel each class constitutes water route, and cooling medium is axially flowed along motor, and bigger with motor interface product, heat dissipation effect compares
It is good;And inlet and outlet can be located at one section of motor by axial water route, and structure is relatively simple;Circumferential water route is cooling medium
Larger with the contact area of motor, heat dissipation is preferable, and water route is smooth, and cooling medium water resistance prosperous in flow process is smaller.But
Be no matter axial water route or circumferential water route, since axial flow path adds up flow or axial flow path adds up flow mistake
It is long, keep temperature difference between the inlet and outlet water larger, i.e. the temperature gradient at both ends is larger.
Invention content
Heat exchange efficiency can be effectively improved in order to solve the above technical problem, the present invention provides a kind of, motor is greatly lowered
Internal temperature, and axial single slot for effectively reducing temperature difference between the inlet and outlet water and motor both ends temperature gradient is double L-shaped and runner reverse flow
Permanent magnet synchronous motor cooling system.

The both ends of runner connects with positive water inlet port and positive water outlet port respectively, and the both ends of reversed runner are respectively with anti-water inlet port and instead
Water outlet port connects, and the port that just intaking, positive water outlet port, anti-water inlet port and anti-water outlet port are arranged on casing;It is described outer
Shell is packed in outside casing, and axial single slot is made to become closing axial passage.
Further include the connection of Y types during above-mentioned axial single slot is double L-shaped and runner reverse flow permanent magnet synchronous motor cooling system
Two branch pipes of pipe, Y type communicating pipes are connect with positive water inlet port and anti-water inlet port respectively;Y type communicating pipes and positive water inlet port and
The connection of anti-water inlet port port section ratio Y type communicating pipes two branch pipes trunk portion internal diameter it is big.
Above-mentioned axial single slot is double L-shaped and runner reverse flow permanent magnet synchronous motor cooling system described in positive water inlet end
Mouth, positive water outlet port, anti-water inlet port and anti-water outlet port are located at the same end of casing.
Compared with prior art, the beneficial effects of the invention are as follows:
Compared with prior art, the beneficial effects of the invention are as follows:It is equipped with positive runner and reversed runner in the axial single slot of the present invention,
Positive runner and reversed cross section of fluid channel are L-shaped, the double L-shaped and shaft orientation flowing channel that section is rectangle are combined into, compared to existing
Uniaxially the water-cooling structure in channel and single-screw channel, the present invention are effectively improved heat exchange efficiency, considerably reduce motor
Internal temperature, and effectively reduce temperature difference between the inlet and outlet water and motor both ends temperature gradient;The present invention by Y type communicating pipes with just into
Water end (W.E.) mouth connect with anti-water inlet port, realize in forward and reverse axial passage it is cold go to end flow velocity, flow it is uniform, and can reduce
Port is impacted.
