Abstract
The utility model discloses a cooling jacket comprising a cylindrical jacket body. The jacket body has a certain thickness. A pipeline for cooling liquid to flow is arranged in the jacket body in the circumferential direction. The jacket body is provided with a cooling liquid inlet and a cooling liquid outlet communicated with the pipeline. The cooling jacket is characterized in that the jacket body is formed by bending a flat plate piece and then welding two ends of the flat plate piece. The cooling jacket of the utility model adopts a fabrication method which is totally different from methods, such as casting, welding after machining, etc., and the cooling jacket is machined through the method that a flat plate provided with a pipeline is fabricated at first, and then the flat plate is bent and welded. Thus, defects with traditional machining methods can be effectively avoided, and advantages, such as low machining cost, beautiful appearance, good cooling efficiency, etc., can be realized.
Description
Technical field
The utility model relates to a kind of coolant jacket, in particular for coolant jacket on motor.
Background technology
Rotor on motor or other similar means, in the process of running up, can produce a large amount of heats.In order to maintain moving in optimum state of motor, must dispel the heat to it.For this reason, many mechanisms have all carried out a large amount of research, as patent CN103001398 and CN103138486.Their solution is all at the additional coolant jacket of motor, is provided with coolant duct in coolant jacket, carrys out cooling motor by cooling fluid.Actual in this coolant jacket of processing, conventionally there are two kinds of processing modes: casting and not cast.When casting, need to after casting, the core that forms pipe section be drawn out from finished product, expend very much man-hour; In addition, casting easily forms sand holes, easily causes in use, produces the phenomenons such as leakage.When not cast, common way is, first processes a columnar housing, then on the periphery wall of housing, processes for cooling fluid flow channel, finally on groove, installs cover plate additional, and welded seal becomes finished product.Not cast processing, processing technology complexity, operation is many, cost is high and not attractive in appearance.Secondly, how, in the situation that not increasing more cost, the efficiency that how to increase cooling fluid heat radiation is also a problem demanding prompt solution.
Utility model content
In order to overcome the problems referred to above, the utility model provides coolant jacket and the manufacture method thereof that a kind of processing technology is simple, radiating efficiency is high.
The technical solution of the utility model is to provide a kind of coolant jacket, it comprises columnar body, described body has certain thickness, described body inside is circumferentially provided with along it pipeline flowing therein for cooling fluid, on described body, be provided with the cooling fluid entrance and the cooling liquid outlet that are communicated with described pipeline, it is characterized in that: described body is to be welded by two ends after flat part bending.
Preferably, on described inner-walls of duct, be provided with several and extend and do not contact from described pipeline one side inwall to opposite side inwall the fin of opposite side inwall.
Preferably, described pipeline is S-shaped is arranged in described body.
Preferably, the described pipeline of manufacturing in flat part and the flat part of described body is integrated.
Preferably, the material of described body is aluminium, aluminium alloy, copper or copper alloy.
The method such as weld after coolant jacket employing of the present utility model and casting, machining is completely different, first makes the flat board with pipeline but adopt, and the mode of rear bending welding is processed.The defect that it can avoid traditional diamond-making technique to exist effectively, and have that processing cost is low, good looking appearance, radiating efficiency advantages of higher.

Fig. 2 is the principle schematic of pipeline work;
Fig. 3 is the longitudinal sectional structure schematic diagram in the part of pipeline.
Embodiment
Below embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of coolant jacket of the present utility model comprises columnar body 10.Body 10 adopts the lighter materials such as aluminium, aluminium alloy, copper or copper alloy, avoids increasing too many weight.In addition, body 10 has certain thickness, this thickness is the common thickness of current industry, according to demands such as size, heat radiation and the processing conditions of motor (being certainly not limited to only for motor), be available thickness by simple test, being one, not need to pay creative work be obtainable parameter.Body 10 inside are circumferentially provided with pipeline 12 along it, are provided with cooling fluid entrance 14 and the cooling liquid outlet 16 of connecting pipe 12 on body 10.Like this, can realize and utilize cooling fluid, for example water carrys out cooling motor.Under prerequisite for the area of dissipation limited and flow, increase the efficiency of heat radiation, the utility model is designed to S shape by pipeline 12 further, and then overall spirality is centered around on body 10.Also further, at the fin 18 of the multiple increase contacts area of the interior design of pipeline 12, fin 18 is to carry out at needs the surperficial stronger sheet metal of increase thermal conductivity that passes through of heat-exchanger rig that heat is transmitted, and increases the heat transfer sheet area of heat-exchanger rig, improves heat exchange efficiency.Fin 18 extends from pipeline 12 1 side inwalls to opposite side inwall, but fin 18 does not contact opposite side inwall.
The manufacture craft of said structure has been carried out great improvement, adopts following steps:
1) melt: high-temperature heating raw material metal is to flow-like molten metal;
2) extrude: in the exit of this melting equipment, at least one central layer is set, then the flow-like molten metal after melting is extruded from the exit high pressure of melting equipment, the flow-like molten metal of extruding is coated by central layer, draws central layer and move to chill station when extruding flow-like molten metal;
3) cooling and shaping: in chill station, the flow-like molten metal of coated central layer is cut off to rear cooling and shaping, obtain the semi-finished product flat part of plate shape;
4) extract out: central layer is extracted out from the flat part sizing, to form pipeline 12 in flat part;
5) bending: flat part is bent to after cylindrical shape;
6) welding: will obtain body 10 after the flat part two ends welding after bending.
Like this, the coolant jacket made is one-body molded, good looking appearance, and technique is simple, cost of manufacture is low.
Form in the process of S shape pipeline 12 in making, further adopt following technique:
4.5) pipeline 12 wall excisions: by the pipeline 12 wall front end mutes between adjacent part two pipelines 12, normally interval excision, to be formed on S shape structure in body 10;
Meanwhile, in step 6, after the pipeline 12 at the flat part two ends after bending being sealed when welding, two ends are welded.
Above embodiment is only the utility model a kind of execution mode wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
