Summary of the invention
Embodiments of the present invention achieve, motor equipment has effective cooling end, wherein said cooling end to be integrated in the housing of described motor and described housing this can not only simple and cheap manufactured can also be responsible for by described housing around stators and rotators carry out effectively, especially uniformly cooling.
Propose a kind of motor according to an aspect of the present invention, described motor has rotor, around the stator of described rotor and the housing around described stator.The cooling duct being configured with coolant entrance, coolant outlet and described coolant entrance and described coolant outlet are circumferentially coupled together in described housing.Between the inwall of described housing and the outer wall of described housing, multiple pin is furnished with in described cooling duct.The feature of described motor is, described housing is constructed by two parts, namely forms the enclosure interior part of inwall and forms the outside part of outer wall.Described pin is one (be that is one with described enclosure interior part or be one with described outside part) at one of this and described housing parts and substantially radially constructs with extending towards wherein another housing parts.At this, described pin should directly adjoin (namely reclining in the mode of Mechanical Contact) to (be that is correspondingly contiguous to described outside part in other words enclosure interior part on) on described wherein another housing component.
In addition, the design of embodiments of the present invention can regard as based on understanding described below and idea.
First, should be design of electrical motor and go out housing with integrated cooling duct, described housing has high cooling power and can manufacture with traditional and pandemic production method as far as possible.The cooling power promoted can realize the lifting of motor sustained capacity, for having to be applied to the lower cost of the permanent magnet in described motor and/or less physical dimension and the less weight of motor that obtains thus.
In traditional motor, the housing needing to be equipped with cooling duct manufactures as the component of one mostly, such as, as complicated aluminium casting.The housing of this one can realize being configured in cooling duct wherein reliable sealing and need water conservancy diversion wherein cooling agent and have heat trnasfer good between stator to be cooled.But it should be noted that, construct the geometry that described cooling duct can utilize and be under many restrictions, described constraint comes from the production method that the housing in order to manufacture this integral type uses.Described cooling duct such as can not be configured in tiny structure in the inside of described housing.
Propose at this, described housing is constructed by two parts.At this, the inwall that enclosure interior part should form described housing needs the inwall of the cooling duct be integrated in described housing in other words, and outside part should form the outer wall of complementary coupling therewith.Described enclosure interior part such as can be configured to can-like and described outside part such as can be configured to tubulose.
In other words, described enclosure interior part such as can be configured to the parts of column, and one end thereof is provided with chassis, and described chassis Flange-shaped Parts leading thread is to the parts of protruding described column.Described outside part can be configured to column equally and have the geometry of tubulose.The parts of described column especially can be columned and preferably mutually arrange coaxially to form housing.At this, the side of the cavity formed between described enclosure interior part and described outside part outwards can be sealed shut from the bottom that the enclosure interior part of described can-like radially outward stretches out.The opposed side of this cavity such as can seal by the other parts of coupling or sealing ring.Can be advantageously, radial spacing between described enclosure interior part and described outside part is selected little as far as possible, thus the cooling agent stream that needs to be guided in therebetween intermediate cavity can be guided well and thus described housing can be made to have high mechanical stability.
Between described enclosure interior part and described outside part, be provided with multiple pin, described pin extends between the inner and outer wall of described housing.Described pin constructs integratedly at one of this and described two housing parts and stretches to wherein another housing parts from this housing parts.In the size of this so described pin of design and described housing parts, the described pin stretched out from one of them housing parts is extended to and wherein another housing parts is directly contiguous on another housing parts described.Described pin such as can be arranged on enclosure interior part and protruding and abut at described outside part place on the outer wall that formed by described outside part integratedly.Can stably locate relative to described enclosure interior part and keep described outside part thus.
In addition, described pin is for promoting the cooling power of the housing crossed by described cooling agent percolation.Described pin crosses described cooling duct and is through the cooling agent circulation of described channel flow thus.In addition, because described pin or be configured on enclosure interior part integratedly, at least mechanically directly abut against on described enclosure interior part, so the cooling agent that such as can be discharged to percolation well via described pin from stator to the heat of described enclosure interior part transmission and cross.
At this, the two-part structure of described housing can enable described pin construct with the arrangement favourable for heat trnasfer.When housing is made up of single part in a traditional way, the structure being positioned at inside, cooling duct generally constructs with relatively large size, then more slightly can construct this structure being arranged in the enclosure interior assembled subsequently when housing is constructed by two parts.
Described pin such as can being greater than every square metre of 100 pins, be preferably greater than the density of every square metre of 1000 pins and arrange.Maximum spacing between adjacent pin such as can be less than 100mm, preferably be less than 30mm.Construct multiple pin little pin in other words in inside, cooling duct with so tight adjacent arrangement, it seems and especially can not realize with one-piece construction housing with traditional manufacture method.
In addition, in simple as far as possible mode, pin is configured on described housing parts and can be realized in the following manner, the surface density being namely arranged in the pin of inside, cooling duct is selected than less in coolant outlet vicinity in coolant entrance vicinity.In other words, described pin does not need to distribute equably at the periphery of described housing arrange but can arrange unevenly, wherein can configure the pin of larger quantity in coolant outlet vicinity than in coolant entrance vicinity and arrange larger pin surface density thus.
Therefore, it is possible to consider following situation: the cooling agent introduced via described coolant entrance in described cooling duct is first colder and therefore have stronger cooling effect, thus a small amount of just enough for the pin improving cooling in this region; Otherwise be provided with higher temperature towards the cooling agent after described coolant outlet flows at a distance due to the heat exchange occurred herein and in coolant outlet vicinity, there is less cooling effect thus, thus the pin surface density that more pin is larger in other words is in this region then favourable.
Can advantageously, described enclosure interior part and/or described outside part are constructed by aluminium.Aluminium casing on the one hand has small weight and the cooling agent can crossed because heat is exported to percolation from stator by the high thermal conductivity of aluminium well on the other hand while having high mechanical stability.But especially described outside part also can be alternatively made up of other materials, such as stainless steel.
Described enclosure interior part and/or outside part especially can be configured to aluminium casting.Aluminium casting has high mechanical properties and can relatively simply manufacture under normal circumstances.But for component, as the integral housing with build-in cavities up to now, be also difficult to structure little structure, such as undersized pin with aluminum casting.For the housing constructed by two parts proposed here, not only described enclosure interior part but also described outside part can both manufacture aluminium casting respectively simply, and the pin that wherein will arrange can not construct but be placed in outside to construct and can structural form be also therefore the structure of little pin in the cavity of inside.As an alternative, described outside part also can differently construct, such as, be configured to extrudate or extrusion pressing type pipe.
Can advantageously at this, the cover section of described enclosure interior part or described outside part constructs multiple pin in parallel to each other with bearing of trend.Preferably all pin of enclosure interior part in other words on outside part that will be arranged on can both construct in parallel to each other with bearing of trend.The pin extended in parallel to each other can manufacture especially simply with cast aluminium method, because described pin is formed by the mold that uses in casting and after this described mold can be deviate from along the bearing of trend of described pin in a straightforward manner.
In order to enable the cooling agent influx of carrying via described coolant entrance advantageously be distributed in inside, cooling duct, in the cooling channel suitable guide rib can be set in coolant entrance vicinity.Described guide rib can extend to the region away from coolant outlet from the region near coolant entrance microsclerly.Described guide rib can extend at this on the whole height of cooling duct or on the Partial Height of cooling duct.
Herein means out, possible feature and advantage of the present invention are illustrated with reference to different execution modes at this.One skilled in the art will appreciate that described feature can combine in an appropriate manner or exchange.
