Description

一种电机水冷却装置
技术领域
本发明涉及一种电机水冷却装置, 具体地说是用于对电机在运行过程中 产生的热量进行散热, 以保证设备的安全运行和性能的正常发挥, 属于电机 技术领域。 背景技术
在工作中, 经常需要对电机在运行过程中产生的热量进行散热, 以保证 设备的安全运行和性能的正常发挥。 目前常用的冷却装置包括风冷、 油冷和 水冷三种方式。在电机应用中, 综合冷却性能和经济成本, 主要以空冷为主。 空气冷却在结构上简单, 费用低廉, 维护方便, 这些显著优点使得空气冷却 首先得到了应用和发展, 但是, 随着电机容量的增加, 电机发热量也在增加, 要强化冷却就必须加大通风量, 从而增加通风损耗, 降低电机效率。
水冷方式由于水的对流换热系数为控制自然换热系数的 150倍以上, 散 热率极高; 同时它又没有油冷方式可能带来的污染和易燃, 和采用强迫风冷 会产生的噪声等问题, 所以得到了越来越广泛的关注。
在已有技术中, 水冷电机的水冷却系统一般分为两种形式, 一种是在电 机外部加水空冷却器, 电机内部热量由内部空气循环系统带到外部水空冷却 器, 并在此完成与外循环系统中的水介质的热交换, 从而不断将电机热量带 走; 另一种是直接在机座内部开设水道, 直接对电机进行冷却, 即机座式水 冷电机。但是一般的机座式水冷电机的进、出水口在同侧,中间没有隔开, 冷 却水道为直线型, 进、 出水口相连, 可能会导致互相干扰, 使水流短路, 冷 却水从进水口流进, 直接从出水口流出, 或只有少量的水经水道后从出水口 流出, 直接导致电机的冷却效果变差。 发明内容
本发明的目的在于克服上述不足之处, 从而提供一种电机水冷却装置, 该装置能在有限的空间内增大冷却水与机体的接触面积, 提高了冷却效率; 且可避免进、 出水口在同侧会互相干扰的弊端。
按照本发明提供的技术方案, 一种电机水冷却装置包括电机壳体, 特征 是: 所述电机壳体的表面设有进水口、 出水口与冷却水道, 所述进水口、 出 水口分别与冷却水道的两端相连接。
所述进水口与出水口处于电机壳体的同一侧, 进水口与出水口中间设有 隔板, 将进水口与出水口隔开, 冷却水通过进水口进入后, 流经冷却水道再 从出水口流出。
所述冷却水道围绕电机壳体一周设置, 其形状为波浪型。
本发明与已有技术相比具有以下优点:
本发明采用了波浪型的冷却水道, 在有限的空间内增大了冷却水与机体 的接触面积, 提高了冷却效率; 进水口与出水口位于机体的同侧, 将中间隔 开, 这样可避免了进、 出水口在同侧会互相干扰的弊端; 也减小了电机的径 向占用尺寸, 而且在同侧安装时非常方便; 大大改善了电机的冷却效果, 提 高电机的工作效率, 避免因温度高而造成的机体变形。 附图说明
图 1为本发明的整体结构示意图。
图 2为本发明冷却水道展开图。
图 3为本发明三维视图。
具体实施方式
下面本发明将结合附图中的实施例作进一歩描述:
如图 1〜图 2所示, 包括进水口 1、 出水口 2、 冷却水道 3、 电机壳体 4。 所述进水口 1、 出水口 2与冷却水道 3分别设置位于电机壳体 4表面, 所述进水口 1、 出水口 2分别与冷却水道 3的两端相连接; 进水口 1与出水 口 2处于电机壳体的同一侧, 进水口 1与出水口 2中间设有隔板 5, 将进水 口 1与出水口 2隔开, 冷却水从进水口流入水道, 需通过冷却水道流经电机 壳体一周带走电机工作产生的热量, 从出水口流出。
图 2所示, 是冷却水道 3的展开图, 其形状为波浪型, 增大了冷却水与 电机壳体 4的接触面积, 提高了冷却效果。
图 3所示, 是电机的三维视图,展示的是冷却水道 3和电机的位置结构, 冷却水道 3在电机壳体 4表面, 直接铸造而成, 既保证了机体强度, 也保证 了冷却效果。
电机工作时, 在电机外部, 带有循环水的装置和本发明的进水口与出水 口连接, 冷却水由进水口流进电机外表面的冷却水道内, 再由出水口流出电 机回到电机外的冷却水循环装置中, 这样就可以在电机壳体的外表面形成水 循环。
