Description

风冷式发动机机体的底座冷却结构 技术领域
[0001 ] 本发明涉及一种风冷式发动机机体的底座冷却结构,属于动力装置技术领域。 背景技术
[0002] 在已有技术中,强制风冷式发动机机体底座结构中,风扇压送过来的冷却空气都 没有能有效的照顾到机体的底座,也是因为以往机体本身的结构没有办法满足的原因。 加 上风冷式发动机润滑油的容量是有限的,机体底座又没有得到有效、充分的冷却导致了本 來温度就很高的润滑油温度没有得到改善。 特别是一些特别紧凑的发动机,这矛盾更加明 显。 这样在长时间的工作中润滑油的品质将很快的失去了原本的润滑性能,润滑油的工作 寿命将大打折扣,使用周期也就因而缩短,经济效益降低。 发明内容
[0003] 本发明的目的在于克服上述不足之处,从而提供一种风冷式发动机机体的底座冷 却结构,该冷却结构能将冷却空气有组织地导向各个散热片,对润滑油的冷却起到很大的 加强作用,降低了润滑油的温度,延长了润滑油的使用寿命。
[0004] 按照本发明提供的技术方案,风冷式发动机机体的底座冷却结构包括发动机 ¾1体 底座;特征是:所述发动机机体底座上布置有散热片在所述发动机机体底座的后端面布置 有进风口,前端面布置有出风口。
[0005] 所述发动机机体底座旁边上布置有能给润滑油起散热作用的支撑柱, 支撑柱为 中空的迎风面为开口结构。 所述发动机机体底座上设置有带一定角度的斜面。
[0006] 本发明与已有技术相比具有以下优点:
木发明能将风扇压送过来的冷却空气有组织的引导到以往冷却不到的机体底座上,将 冷却空气有组织地导向各个散热片,对润滑油的冷却起到很大的加强作用,降低了润滑油 的温度,延长了润滑油的使用寿命。 附图说明
[0007] 图 1为本发明底座冷却结构轴测示意图。
[0008] 图 2为本发明底座冷却结构平面示意图。 具体实施方式
[0009] 下面本发明将结合附图中的实施例作进一步描述:
如图 1〜图 2所示,包括进风口 1、散热片 2、带有斜度的底座 3、出风口 4、支撑柱 5等。
[0010] 本发明实施例的发动机是风冷发动机,用于例如工作机等。
[001 1 ] 本发明釆用在发动机机体底座 3的后端开有进风口 1 ,前端面开有出风口 4。所述 发动机机体底座 3上设置有带一定角度的斜面;在发动机机体底座 3上布有散热片 2;在所 述的发动机机体底座 3旁边布置有能给润滑油起散热作用的支撑柱 5,支撑柱 5为中空的迎 风面为开口结构。
[0012] 本发明通过将冷却风引导到底座的散热片上,机体底座冷却结构巧妙的组织气流 对机体底座进行冷却,进而润滑油的温度也就得到改善,中空结构的支撑柱 5不仅能对机 体起加强作用,重要的是还利用其内表面对润滑油进行冷却,进而整机的润滑油温度得到 改善。
