According to foregoing manufacture method, cooling passage is from motor case part by cooling passage shape physical model
Formed after middle removal in motor case part.Therefore, it will be apparent to one skilled in the art that cooling passage shape entity
The shape of model determines the shape of the cooling passage formed in motor case part.In this application, in order to more straight
The construction of the explanation cooling passage of sight, will be actual come intermediate description by describing the construction of cooling passage shape physical model
The construction of cooling passage.
Refer to shown in Fig. 2 and 4, a kind of cold cooling device of motor liquid of embodiment of the invention includes motor
Cabinet parts 9, the cylindrical shape of motor case part 9, it is surrounded by cylindrical circumferential wall forms hollow cavity 90.In motor case
There is the cooling passage 11 that lost pattern casting is formed, cooling passage 11 has the part of bending in the perisporium of part 9.
Fig. 3 shows the schematic diagram of the cooling passage shape physical model 110' shown in Fig. 2.As shown in Figure 3 the first
In embodiment, cooling passage shape physical model 110' have it is spiral do not have forked passage entity 11',
Spirality channel entity 11' two ends set boss 111', and 5 boss of setting in the middle part of passage entity 11' respectively
111', that is to say, that altogether there is provided 7 boss 111'.Therefore, formed using cooling passage shape physical model 110'
Fig. 4 shown in cooling passage 11 have and spiral do not have forked passage.Set on the perisporium of motor case part 9
There are at least two holes 111 connected with cooling passage 11, at least one hole 111 is arranged on spiral shape cooling passage 11
End.At least one hole 111 is used as liquid outlet as inlet and at least one hole 111.It is alternatively possible in motor
The multiple holes 111 connected with cooling passage 11 are provided with the perisporium of cabinet parts 9, the coolant of powder is broken into due to shaking

Also, circular passage entity 21', 31' are connected with straight passage entity 21', 31'.Except that, second shown in Fig. 5
The cooling passage shape physical model 210' for planting embodiment is by extending along the circumferencial direction of motor case part
Multiple parallel circular passage entity 21' and with the axle of the edge of the plurality of parallel circular passage connection parallel to motor case part
To two parallel straight passage entity 21' of direction extension constitute, two kinds of boss for forming inlet and liquid outlet
211' is separately positioned on the position that a circular passage entity 21' at middle part is connected with two straight passage entity 21'.And scheme
The cooling passage shape physical model 310' of the third embodiment shown in 6 is by the circle along motor case part 9
Two parallel circular passage entity 31' and circular passage entity 31' parallel with this two connection of circumferential direction extension along flat
Row is constituted in each and every one many straight parallel shape passage entity 31' that the axially direction of motor case part extends, for forming feed liquor
Two kinds of boss 311' of mouth and liquid outlet are separately positioned on what two axially symmetric straight passages were connected with two circular passages
Position.
It will be apparent to one skilled in the art that using the cooling passage shape entity of these types shown in Fig. 5 and Fig. 6
The cooling passage of model 210', 310' formation（It is not shown）The cross aisle of parallel connection is respectively provided with, it is included along motor case portion
At least two parallel circular passages and prolong along the axially direction parallel to motor case part that the circumferencial direction of part extends
At least two parallel straight passages stretched, also, circular passage is connected with straight passage.Except that, using shown in Fig. 5
The cooling passage of cooling passage shape physical model 210' formation of second of embodiment be by along motor machine
Multiple parallel circular passages of the circumferencial direction extension of case member and with the edge of the plurality of parallel circular passage connection parallel to
Two parallel straight passages of the axially direction extension of motor case part are constituted, and inlet and liquid outlet are to be separately positioned on
The position that one circular passage at middle part is connected with two straight passages.And use the third specific embodiment party shown in Fig. 6
The cooling passage of the cooling passage shape physical model 310' formation of formula is prolonged by the circumferencial direction along motor case part
Axial direction of the edge that the two parallel circular passages stretched and circular passage parallel with this two are connected parallel to motor case part
Direction extension each and every one many straight parallel shape passages constitute, inlet and liquid outlet can be separately positioned on axially symmetric two
The position that straight passage is connected with two circular passages.Because cooling passage has cross aisle in parallel, coolant exists
To concurrently it be flowed by plurality of passages in cooling passage, so as to obtain relatively uniform cooling effect.
