Abstract

本发明提供一种汽车电机的热管冷却装置，该装置在定子外圆的轴向，均匀布有数条凹槽，凹槽内埋设热管，靠近后盖的定子端部，将数根热管连通，形成一形圆形热管，与一根热管连通，构成一段引出的热管，与铝壳固定接触，或与散热片固定接触；另在电机转轴的轴心内，轴向设置一热管。本发明的优点在于，采用热管作为散热器，冷却效果好，冷却装置体积小。在自然对流状态下，电机的轴心温度下降150C，整体电机温度可控制在1000C内。若设置辅助散热叶片，则能提高电机的可靠性和使用寿命。

Description

一种汽车电机的热管冷却装置
技术领域
本发明涉及电机技术领域，特别是有关于电机的冷却降温装置。 
背景技术
目前，电机的冷却、降温，大都是采用风冷，占用空间体积大，降温效果差，导致电机效率低。 
发明内容
为解决前述问题，本发明提供一种汽车电机的热管冷却装置，该装置是在定子外圆的轴向，均匀布有数条凹槽，凹槽内埋设热管，靠近后盖的定子端部，将数根热管连通，形成一形圆形热管，与一根热管连通，构成一段引出的热管，与铝壳固定接触，或与散热片固定接触；另在电机转轴的轴心内，轴向设置一热管。 
本发明的优点在于，采用热管作为散热器，冷却效果好，冷却装置体积小。在自然对流状态下，电机的轴心温度下降150C，整体电机温度可控制在1000C内。若设置辅助散热叶片，则能提高电机的可靠性和使用寿命。 
附图说明
附图1是本发明剖视图。 
附图2是热管布设在定子轴向的示意图。 
附图3是图2的A-A向视图。 
附图4是靠近后盖的定子端部，将数根热管连通，形成一根圆形热管引出的示意图。 
附图5是汔车电机的立体外形图。 
图中标号说明： 
1-  电机铝壳（桶形）；2-电机转子；3-电机定子；4-电机转轴；5-转轴
内的热管；6-铝壳内侧定子上的热管；7-线圈；8-轴承；9-储液箱；
10-散热片；11-铝壳前盖；12-铝壳后盖；13-热管引出端；14-后盖定子端部圆形热管（与定子上热管6连通）。
具体实施方式
请参阅附图1、2所示，本发明在定子3外圆的轴向，均匀布有四条凹槽，凹槽内埋设热管6，靠近后盖12的定子3端部，将四根热管连通，形成一形圆形热管14，与一根热管连通，构成一段引出的热管13，热管13与铝壳1固定接触，或与散热片10固定接触，与铝壳或散热片接触的热管13，构成热管冷却端，使定子的热量传到铝壳和散热片上冷却，达到散热效果；另在电机转轴4的轴心内，轴向设置一热管5，使转轴中心的热量传到铝壳外端。 
与铝壳1固定接触，或与散热片固定接触；另在电机转轴4的轴心内，轴向设置一热管5。 
热管作为换热器，是上世纪发明的技术，本发明采用外购的超导热管，为本发明降温散热器件。
