Technical Problem
然而，该技术存在显著问题：由于相关技术中的冷却液需与漆包线直接接触，致使冷却液选材局限且电机内部必须实施复杂全密封以防泄漏的问题，同时整体结构设计及生产工艺也变得更为复杂
Benefits of technology
[0018]1、环形基体通过集成同轴嵌套的内外双集液腔体构建出高效双循环冷却回路，其中外集液腔体承接进液口的冷却介质输入并经由底部通孔分流至各散热翅片，内集液腔体则汇聚吸热后的介质通过出液口集中排出，辅以腔体V型断面设计强化承压能力与流动效率，配合顶面一体化成型的进液口与出液口实现无管路直连的密封可靠性，同时双腔体结构通过环形基体的实体金属壁物理隔绝冷却介质与电机内部电磁组件，彻底消除冷却液接触定子铁芯或绕组导致的绝缘劣化风险，保障电化学兼容性与长期运行安全性，从根本上杜绝换热介质泄漏风险。

Abstract
The utility model provides a kind of motor slot cooling structure of isolated heat exchange medium, including annular matrix and multiple radiating fins;Annular matrix is annular structure, and multiple radiating fins are strip structure and are evenly distributed in the lower end surface of annular matrix;The top of each radiating fin is integrally connected with annular matrix;Annular matrix is equipped with coaxially arranged inner liquid-collecting cavity and outer liquid-collecting cavity, both are annular structure, and inner liquid-collecting cavity is located in the inside of outer liquid-collecting cavity.The motor slot cooling structure of isolated heat exchange medium described in the utility model solves the problem that the cooling liquid in the related technology needs to be in direct contact with the enameled wire, which limits the selection of the cooling liquid and requires a complex full seal inside the motor to prevent leakage.
