It is high.In a limited space under size and cost limitation, cooling system radiating efficiency how is improved as important research topic.
Utility model content
To solve the above-mentioned problems, the purpose of this utility model is to provide a kind of water-cooled motor shells, on it rationally
Water channel is set with the contact area of the cooling medium and inner casing that pass through from water channel, to improve heat dissipation effect.
In order to achieve the above purpose, the utility model uses technical solution below:
A kind of water-cooled motor shell, including inner casing and outer cage, outer cage are mounted on outside inner casing, inner casing and outer
Multiple partition muscle are equipped between casing, partition muscle is separated out multiple water channel units, water channel unit between inner casing and outer cage
Be interconnected the water channel formed for the cooling medium that circulates, and outer cage is equipped with the water channel entrance being connected to water channel and water channel goes out
Mouthful；The inner sidewall of all or part of water channel unit is equipped with the concaveconvex structure for increasing water channel unit surface area.This is practical new
Type by setting partition muscle water outlet is isolated between interior outer cage, can on the outer peripheral surface of inner casing arrangement water as much as possible
Road unit increases the contact area of the cooling medium and inner casing that pass through from water channel；And by being formed in water channel side wall
Concaveconvex structure further increases the surface area of water channel.
Preferably, partition muscle is along inner casing and outer cage circumferentially around setting；Or partition muscle is distributed in inner casing
Outer peripheral surface on along the axially extending of inner casing and outer cage.Partition muscle is differently arranged, can be on electric machine casing
Form spiral channel, circumferential water channel, axial water channel etc..
Preferably, inner casing and outer cage independently form, partition muscle can be integrally formed with inner casing, outer cage
Water outlet unit is sealed off from periphery.Setting can simplify the installation and processing of motor case in this way.
As optional technical solution, inner casing, outer cage and partition muscle are integrally formed.
Preferably, being set as bulge-structure on the inner sidewall of water channel unit, the bulge-structure, which can be set, to be constituted
Partition muscle side wall, the outer surface of inner casing and one of inner surface of outer cage of water channel unit or it is a variety of on.It is designed as convex
Case strength can be increased on the basis of increasing the area of water channel unit inner surface by playing structure, so as to improve vibration and noise.
Also, bulge-structure can straight forming, without finishing, it is low to be conducive to processing cost.
The setting direction of bulge-structure is determined according to water channel form, preferably, extension side of the bulge-structure in water channel
To identical as the flow direction of the cooling medium in water channel unit, the flow resistance in water channel unit can be minimized.
In conclusion the water-cooling motor cabinet of the utility model, provides a kind of completely new channel structure form, passes through water channel
Middle increase convex ribs increase the contact area of coolant liquid and casing, improve the radiating efficiency of motor.

Specific embodiment
The preferred embodiment of this patent is described in further detail with reference to the accompanying drawing.
A kind of water-cooled motor shell, including inner casing 1 and outer cage 2, outer cage 2 are arranged outside inner casing 1, inner housing
1 and outer housing 2 can be integrally formed or split settings.It is equipped with multiple partition muscle 3 between inner casing 1 and outer cage 2, separates muscle 3
Multiple water channel Unit 4 for the cooling medium that circulates are separated out between inner casing 1 and outer cage 2, all water channel Unit 4 are mutual
Connection forms water channel 4, and outer cage 2 is equipped with 4 entrance of water channel being connected to water channel 4 and water channel 4 exports.
In embodiment, partition muscle 3 can be along inner casing 1 and outer cage 2 circumferentially around setting, specific set-up mode
On, it can be arranged with spiral or be circumferentially arranged, such as Fig. 1 and Fig. 3；Alternatively, partition muscle 3 can be distributed on the outer peripheral surface of inner casing 1
