Description
一种电子负载机
【技术领域】
本发明涉及电源制造领域, 更具体的说, 涉及一种电子负载机。
【背景技术】
电子负载机是针对各式 S.P.S. (转换式电源供应器)设计的多功能电子负 载仪器, 专门提供给生产部门, 检验部门或是开发部门使用。 电子负载机可以 模拟真实环境中的负载 (用电器) 来检测电源的好坏。 其功能相当多, 包括可 以调节负载大小, 以及短路, 过流, 动态等等。 电子负载的原理是控制内功率 或晶体管的导通量 (量占空比大小), 靠功率管的耗散功率消耗电能的设备, 它能 够准确检测出负载电压, 精确调整负载电流, 同时可以实现模拟负载短路, 模 拟负载是感性阻性和容性, 容性负载电流上升时间。
电子负载机由于要模拟各种用电设备, 电路中的晶体管作为电流的控制器 件以及被测电源的负载, 其发热量较大, 从而需要在电子负载机内设置较大体 积的散热组件, 并将晶体管设置在散热组件上, 使得晶体管所发出的热量能及 时通过散热组件散发出去。 为了确保散热效率, 散热组件制造成一长方体形状, 以形成相对直的散热通路。 如图 1 所示为现有电子负载机的散热组件设置示意 图, 散热组件 110竖向设置在电子负载机的机箱 100内, 其散热口 103设置在 机箱的后面板 101上。 而由于散热组件 110的长度较长, 致使机箱 100的竖向 长度较长, 在散热组件 110 的两侧, 并没需要设置的其它组件, 从而在散热组 件的两侧均为不必要的空间, 这样机箱 100 内部的空间浪费较大, 造成了电子 负载机体积较大, 不方便放置及搬运。
【发明内容】
本发明所要解决的技术问题是提供一种散热性能较好、 体积较小的的电子 负载机。
本发明的目的是通过以下技术方案来实现的: 一种电子负载机, 包括: 机 箱及散热组件, 所述散热组件横向设置在机箱内。
优选的, 所述散热组件包括: 散热片以及用于固定散热片的散热框架, 所 述散热框架固定在所述机箱上, 所述散热组件的散热口设置在所述机箱的侧边 框上。 通过散热框架将散热片固定在机箱上, 从而可以合理的布置散热片的位 置及方向, 另外, 通孔将散热口设置在机箱的侧边框上, 使得散热组件直接与 机箱外部空气接触, 提高散热效率。
优选的, 所述散热片分别设置在所述散热框架的上下端。 通过上下均设置 散热片以增加散热面积, 提高散热效率。
优选的, 所述散热框架的上下端上的散热片相对设置。 使得热量的散发途 径有序, 从而提高散热效率。
优选的, 所述上下端的散热片之间留有间隔。 使得散热组件内有一个空气 流通的空间, 以提高散热效率。
优选的, 所述散热组件的一端设置有散热风扇。 通过散热风扇提高空气流 通的速度, 从而提高散热效率。
优选的, 所述散热风扇设置在所述散热组件的散热口上。 通过风扇及时将 热空气往散热口方向引导排出, 提高散热效率。
本发明由于将电子负载机的散热组件横向设置在机箱的内部, 这样, 机箱 在竖向的宽度将得到减小, 同时, 横向设置的散热组件充分利用了机箱内的中 间空间, 从而使得电子负载机的机体可以变得更小, 节约机箱材料使用同时更 方便电子负载机的放置和般运。
【附图说明】
图 1是现有电子负载机的内部散热组件的布置结构示意图,
图 2是本发明实施例的电子负载机的内部散热组件及其它组件的布置结构 筒图,
图 3是本发明实施例的电子负载机散热组件内部散热片布置结构示意图。 其中: 100、 机箱, 101、 后面板, 103、 散热口, 104、 前面板, 110、 散热 框架, 111、 散热片。
【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
如图 2所示为本发明所述的电子负载机, 其包括: 机箱 100以及横向设置 在机箱 100内的散热组件(图中只示出了散热组件的散热框架 110 ), 散热组件 的散热口 103设置在机箱 100的侧边框上。 由于将电子负载机内散热组件的散 热口 103设置在机箱的侧边框上, 使得散热组件可以横向设置在机箱 100的内 部, 这样, 机箱 100在竖向的宽度将得到减小, 同时, 为了接线等操作的方便, 电子负载机内部的线路板、 变压器等元件多设置在机箱 100的后面板 101 以及 前面板 104上, 致使中部空间较大浪费, 而横向设置的散热组件充分利用了机 箱内的中部空间, 从而使得电子负载机的机体可以变得更小, 节约机箱材料使 用同时更方便电子负载机的放置和搬运。
散热组件包括: 一矩形的散热框架以及设置在散热框架内部的散热片。 如 图 3所示为散热组件的内部散热片的布置示意图, 散热片 111分别设置在散热 框架 110的上下端, 这样散热组件的上下部分都设置有散热片 111 , 提高了散热 面积, 从而提高散热效率。
散热框架 110内部的散热片 111成相对设置,这样,使得散热组件内部的热 量散发途径有序, 从而使得散热途径更短, 提高散热效率。
散热组件内的上下散热片 111 之间留有间隔, 这有使得散热组件内能够留 有一个空气流通的空间, 以提高散热效率。 当然, 本实施例中, 如图 3 所示, 散热组件内部的散热片 111 排布时在散热组件内形留有一个十字的间隔空间, 以确保空气的流通性。
为了提高空气流通的速度, 提高散热效率, 还可以在散热组件的一端设置
散热风扇。 本实施例中, 散热风扇设置在散热组件的散热口 103处, 散热口 103 即设置在机箱 100 的侧边框上, 这样可以直接将散热组件内已经换热的空气排 出, 进而提高了散热组件的散热效率。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明, 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干筒单推演或替 换, 都应当视为属于本发明的保护范围。
