Description
Technical field
The utility model is related to a kind of fluid-cooled electrical machine and its casing.
Background technology
With the development of new energy industry, more strict requirements are proposed to the automobile motor of small-volume large-power density,
It is always direction that new energy motor needs constantly to be lifted that attractive in appearance, safety, heat-transfer effect be good etc..
Electric machine casing the more commonly used at present, is roughly divided into axial water channel housing, circumferential water channel housing, but be due to axial direction
The water channel area coverage of water channel housing is smaller, therefore the radiating efficiency of its water channel is relatively low, and circumferential water channel housing typically uses ring
Shape water channel housing or spirality channel housing, are such as disclosed in Authorization Notice No. is CN103023219B Chinese patent document
The cold liquid of supplying water is provided with a kind of water-cooled machine, the housing of the motor and flows through whole spiral channel, by the heat of casing
Flowed out after taking away from delivery port.Spiral channel housing as shown in Figure 1, including housing 1 and the spiral channel being arranged on housing 1
The water channel good heat dissipation effect of 2 this structures, radiating efficiency is better than axialmode channel structure, but the structure is needed when casing is processed
Internal and external cycle welding is wanted, outward appearance is poor, it is high to welding process requirement, if not prison welding is solid, sealing can be caused poor, water channel is suppressed
The problem of infiltration.
The content of the invention
The purpose of this utility model is to provide a kind of fluid-cooled electrical machine, to solve the casing of fluid-cooled electrical machine of the prior art
The problem of welding quality requires higher；The purpose of this utility model, which is also resided in, provides a kind of casing of the fluid-cooled electrical machine.
To achieve the above object, the technical scheme of the utility model casing is：
Casing, including endoporus constitute the built-in pipe of cooling liquid flowing channel, in addition to form whole with the built-in pipe by pouring into a mould
The cast shell of body structure.
Built-in pipe is located inside the shell wall of cast shell.
Built-in pipe is the helix tube being coaxially set with cast shell.
Welding or integrally formed with feed liquor guiding tube at the inlet of built-in pipe, the axis of feed liquor guiding tube and built-in pipe
Center line is tangent.
Welding or integrally formed with going out liquid guiding tube at the liquid outlet of built-in pipe, goes out the axis and built-in pipe of liquid guiding tube
Center line is tangent.
The technical scheme of the utility model fluid-cooled electrical machine is：
Fluid-cooled electrical machine, including casing, casing include endoporus constitute cooling liquid flowing channel built-in pipe, in addition to by cast with
The built-in pipe forms integrally-built cast shell.
Built-in pipe is located inside the shell wall of cast shell.
Built-in pipe is the helix tube being coaxially set with cast shell.
Welding or integrally formed with feed liquor guiding tube at the inlet of built-in pipe, the axis of feed liquor guiding tube and built-in pipe
Center line is tangent.
Welding or integrally formed with going out liquid guiding tube at the liquid outlet of built-in pipe, goes out the axis and built-in pipe of liquid guiding tube
Center line is tangent.
The beneficial effects of the utility model are：Compared to prior art, the machine of the fluid-cooled electrical machine involved by the utility model
Shell, including endoporus constitute the built-in pipe of cooling liquid flowing channel, in addition to form integrally-built pour with the built-in pipe by pouring into a mould
Shell is noted, integrally formed cast shell ensure that the protection of casing and sealing property are greatly promoted, it is to avoid because of welding quality not
The phenomenon that cooling passage seeps water caused by enough, and the setting of pipeline is various informative, not by the processing technology of existing casing
Limitation, it is aesthetic in appearance, it is simple in construction.

Fig. 2 is the specific embodiment structural representation of the casing of the utility model fluid-cooled electrical machine；
Fig. 3 is Fig. 2 sectional view along casing axis direction；
Fig. 4 is another example structure schematic diagram of the present utility model.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment of casing of the present utility model, as shown in Figure 2 to Figure 3, the casing of the fluid-cooled electrical machine include housing
With endoporus constitute cooling liquid flowing channel built-in pipe 4, wherein, housing is integrated the cast shell 3 of moulding by casting, by cast with it is pre-buried
The formation overall structure of pipe 4, built-in pipe 4 is helix tube, and it is located inside the shell wall of cast shell 3, and built-in pipe 4 is good by heat-conducting effect
Cylindrical metal pipe spiral be bent to form, cast shell 3 be by liquid（Or semisolid）Metallic solution moulding by casting, wherein pre-buried
Pipe, which has on the sidewall periphery face of cast shell 3 at inlet and liquid outlet, inlet, to be integrally formed by feed liquor guiding tube 5, is gone out
It is integrally formed at liquid mouthful by going out liquid guiding tube 6, globality is more preferably.Feed liquor guiding tube 5 and the extension axis difference for going out liquid guiding tube 6
Center line with built-in pipe is tangent, it is ensured that liquid smoothly enters, it is to avoid impact and vortex are produced.
During fabrication, after metal built-in pipe fixed placement spiral bent, using suitable mould and technique, then adopt
With suitable technique pouring liquid（Or semisolid）Metallic solution, makes after the fully wrapped around built-in pipe of solution, curing molding to be cooled,
Housing and built-in pipe are shaped to an entirety with regard to perfection, and its sealing and degree of protection are higher.
In other embodiments, the setting form of built-in pipe can be by laterally setting, along the circumferential ring of housing along housing axis
Replaced to setting etc.；Feed liquor guiding tube also can be by by after cooling and shaping, in housing with least one gone out in liquid guiding tube
The upper weld nipple at the position at the two ends of metal tube is formed respectively；Feed liquor guiding tube and go out liquid guiding tube can not be with built-in pipe
Center line it is tangent；The lead angle of built-in pipe can be adjusted according to actual conditions；The inner section of built-in pipe can be circular, also may be used
To be square other sections of grade, another embodiment as shown in Figure 4, the inner section of its built-in pipe is rectangle；Outer section of built-in pipe
Face can be circular, can also be replaced by the other shapes such as square, special-shaped.
