光学发动机的冷却方法及装置
技术领域
本发明涉及一种光学发动机的冷却方法及装置。 背景技术
现有的光学发动机， 其缸套由透明石英玻璃制成， 通过透明缸套可观测缸内的情 况， 是发动机研发的一种重要手段。 在燃烧过程中， 发动机产生的热量传递给透明缸 套， 为了使透明缸套正常工作， 需对缸套进行冷却， 以减少整个缸壁的热梯度和由此 而产生的热应力。 发明内容
本发明要解决的技术问题在于提供一种光学发动机的冷却方法及装置， 能够有效 地实现对光学发动机的冷却。
本发明所要解决的技术问题是通过如下技术方案实现的：
本发明提供了一种光学发动机的冷却方法， 发动机燃烧的热量传递到透明缸套， 透明缸套将热量传递到加长活塞， 所述加长活塞将热量传递到石墨冷却块， 石墨冷却 块将热量通过外部循环水传递出去。
在透明缸套的下方设有两石墨冷却块， 石墨冷却块镶嵌在发动机支撑壳体内， 石 墨冷却块与加长活塞侧面支撑立柱相接触。
石墨冷却块内侧形状与透明缸套内侧形状相匹配。
发动机支撑壳体外设有循环水壳体，石墨冷却块外侧与循环水壳体内的水腔相通。 石墨冷却块与发动机支撑壳体之间、 循环水壳体与发动机支撑壳体之间均设有密 封圈。
循环水壳体的进水口和出水口接外部循环水路， 通过控制外部循环水路的水温控 制外循环水壳体内的水腔水温。
本发明还提供了一种光学发动机的冷却装置， 用以实现前述的冷却方法， 透明缸 套内设有加长活塞， 所述透明缸套的下方设有两石墨冷却块， 石墨冷却块镶嵌在发动 机支撑壳体内， 石墨冷却块与加长活塞侧面支撑立柱相接触； 发动机支撑壳体外设有 循环水壳体， 石墨冷却块外侧与循环水壳体内的水腔相通。 石墨冷却块内侧形状与缸套内侧形状相匹配。
石墨冷却块与发动机支撑壳体之间、 循环水壳体与发动机支撑壳体之间均设有密 封圈。
本发明具有的有益效果：
铝制加长活塞和石墨冷却块都具有较好的热传导系数， 加长活塞在上下运动过程 中， 其侧面支撑立柱始终与石墨冷却块相接触， 使得发动机燃烧产生的热量可以传递 到石墨冷却块， 石墨冷却块再将热量通过外部循环水传递出去。本发明结构设计简单， 能够取得较好的光学发动机冷却效果。 附图说明
图 1为本发明在光学发动机中的部分结构布置示意图；
图 2为本发明光学发动机中的冷却工作部分的结构示意图。 具体实施方式
如图 1所示， 透明缸套 2内设有加长活塞， 透明缸套顶部为缸盖 1， 加长活塞与 透明缸套 2之间设有活塞环 4， 加长活塞由顶面的透明石英玻璃 3和侧面支撑立柱 5 构成， 前述为现有技术。
如图 1-2所示，透明缸套 2的下方设有两石墨冷却块 6，石墨冷却块 6镶嵌在发动 机支撑壳体 7内， 石墨冷却块 6与加长活塞侧面支撑立柱 5相接触， 石墨冷却块内侧 形状与缸套内侧形状相匹配。 发动机支撑壳体 7外设有循环水壳体 8， 石墨冷却块 6 外侧与循环水壳体 8内的水腔 10相通。石墨冷却块 6与发动机支撑壳体 7之间设有密 封圈 9、 外循环水壳体 8与发动机支撑壳体 7之间设有密封圈 13， 用以防止冷却水的 泄漏。 循环水壳体 8的进水口 12和出水口 11接外部水路， 通过控制外部水路的水温 控制水腔 10内的水温。
光学发动机燃烧产生的热量有一部分经透明石英玻璃 3传递给加长活塞的侧面支 撑立柱 5 ; 有一部分热量传递给透明缸套 2， 传递到透明缸套的热量经活塞环 4也传递 到加长活塞的侧面支撑立柱 5。 由于活塞上下运动过程中， 活塞侧面支撑立柱 5始终 与石墨冷却块 6相接触， 热量沿加长活塞的侧面支撑立柱 5向下传递到石墨冷却块， 最终热量由外部循环冷却水带走。
最后所应说明的是： 以上实施例仅用以说明本发明而非限制， 尽管参照较佳实施 例对本发明进行了详细说明， 本领域的普通技术人员应当理解， 可以对本发明进行修 改或者等同替换， 而不脱离本发明的精神和范围， 其均应涵盖在本发明的权利要求范 围当中。
