Abstract
The utility model relates to a water cooling structure used for a permanent magnet synchronous motor. The water cooling structure comprises helical grooves disposed on an outer contour surface of a casing; a housing which is fixedly disposed outside the casing and makes the helical grooves form enclosed helical channels, wherein two ports of the helical channels as a whole are a water inlet port and a water outlet port; and a water inlet nozzle stand and a water outlet nozzle stand which are fixedly arranged on the housing and are communicated with the water inlet port and the water outlet port, respectively. The water cooling structure is characterized in that the helical grooves are multiple helical grooves arranged in a parallel manner, and the formed helical channels are multi-helix channels. Compared with a conventional water cooling structure with a single helical channel, the water cooling structure with multiple helical channels, the circulation volume of cooling water is increased, that is to say, the circulation speed of cooling water is increased in a phase manner, so that heat generated in a motor is taken away rapidly. Therefore, the heat exchange efficiency of the motor is improved, the temperature inside the motor is greatly reduced, the operation performance of the motor is improved, and the service life of the motor is prolonged. In addition, with less demands of water pressure, a smaller water pump can be selected and then costs are lowered.
Description
Technical field
The utility model relates to motor cooling technology field, particularly a kind of water-cooling structure for permagnetic synchronous motor.
Background technology
In the motor use procedure, water-cooled is the normal a kind of type of cooling adopted on permagnetic synchronous motor.The concrete structure of water-cooled is at present: a helicla flute is set on the outer surface of motor case, by being packed in the outer shell of casing, make the helicla flute sealing become helical duct, water inlet tap seat and the faucet seat be communicated with the two-port of helical duct is set on shell.In use, by the water inlet tap seat, inject cooling water, cold air water flows to faucet seat end along helical duct, then by the faucet seat, discharges.Cold air water is in helical duct in mobile process, and the heat that motor internal is produced is taken away, and has realized that motor is cooling.This water-cooling structure in actual use, particularly at the diameter of permagnetic synchronous motor hour, exists heat exchange efficiency low, the problem of motor internal accumulated heat, and in addition, the pressure of supply water of cooling water is also larger.
Summary of the invention
The utility model provides a kind of for the water-cooling structure on permagnetic synchronous motor for solving the technical problem existed in known technology, this water-cooling structure improves motor heat exchange efficiency, decrease motor internal temperature on the one hand, thereby improve the runnability of motor and extend motor useful life, reduced on the other hand the demand to pressure of supply water.
The technical scheme that the utility model is taked for the technical problem existed in the solution known technology is:
A kind of for the water-cooling structure on permagnetic synchronous motor, comprise the helicla flute be located on the casing outer surface; Comprise and be packed in the outer shell of casing, described shell makes helicla flute form the helical duct of sealing, and the two-port of helical duct is water inlet port and water outlet port; Comprise and be packed on shell the faucet seat that is communicated with respectively the water inlet tap seat of water inlet port and is communicated with the water outlet port, it is characterized in that: described helicla flute is many helicla flutes that be arranged in parallel, and formed helical duct is many helical ducts.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of for the water-cooling structure on permagnetic synchronous motor, comprise the helicla flute be located on casing 1 outer surface; Comprise and be packed in the outer shell 2 of casing, described shell makes helicla flute form the helical duct 3 of sealing, and the two-port of helical duct is water inlet port 31 and water outlet port 32; Comprise and be packed on shell the faucet seat 5 that is communicated with respectively the water inlet tap seat 4 of water inlet port and is communicated with the water outlet port.Described helicla flute is many helicla flutes that be arranged in parallel, and formed helical duct is many helical ducts.Concrete, the water inlet tap seat all is communicated with the inlet end of each helical duct, and the faucet seat all is communicated with the water outlet end of each helical duct.When machine operation, cooling water leads to the inter-sync operation at a plurality of spirals, from inlet end separately, flows into, and after heat exchange, from water outlet end separately, flows out.
In said structure, described spiral fluted quantity is preferably two, and described helical duct is preferably the double helix passage.
The foregoing is only the better example of executing of the present utility model, not be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all fall into technical scope of the present utility model.
