具体实施方式
下面结合附图和实施例，对本申请的具体实施方式作进一步详细描述。以下实施例用于说明本申请，但不用来限制本申请的范围。
如图1所示，本申请的进气装置包括增压器10、与增压器10连接的连接管20、与连接管20相连的中冷器30、与中冷器30相连的进气歧管40、以及位于中冷器30和进气歧管40之间的节气门50。
请一并参阅图2，本实施例中的增压器10为涡轮增压器，其设于发动机气缸盖60的左上方，与气缸的排气口连接。具体而言，本申请的增压器10包括废气入口11、废气出口(图未示)、空气入口13、以及空气出口14，其中，废气入口11与气缸的 排气口连接，废气出口与汽车的排气管连接，空气入口13与空气滤清器连接，空气出口14与连接管20连接。经发动机排出的废气经废气入口11进入增压器10，冲击涡轮机高速运转，带动同轴的压缩机高速转动，将经空气滤清器过滤后的新鲜空气吸入压缩机压缩增压，然后将增压后的空气经空气出口14压送至连接管20中。在本申请中，位于废气入口11和涡轮机之间的废气进入管15的高度大于废气入口11的高度，也就是说，废气进入管15相对废气入口11向上翻折，此种结构可以使增压器10的空气出口14更加靠近中冷器30，缩短增压器10和中冷器30之间的连接管20的长度，使整个装置的结构更加紧凑。在本申请的其它实施例中，增压器10也可采用下翻结构，即废气进入管15相对废气入口11向下翻折，这种结构与增压器10为上翻结构时相比，增压器10和中冷器30之间的高度差稍微大一些，因此对应的连接管20的长度稍长一些，但整个装置的结构仍比较紧凑。
连接管20的形状与增压器10的空气出口14和中冷器30的气体通道入口31a之间的相对位置有关。在图1所示实施例中，增压器10的空气出口14低于中冷器30的气体通道入口31a，且增压器10的空气出口14位于中冷器30的气体通道入口31a的左侧，对应的连接管20为先由下向上倾斜延伸，然后由上往下倾斜延伸的V字型结构，即连接管20为顶点朝上的V型结构。在增压器10采用下翻结构的实施例中，连接管20的形状和增压器10采用上翻结构时类似，但由于增压器10的空气出口14与中冷器30的气体通道入口31a之间的高度差增加，因此，连接管20的长度会大于增压器10采用上翻结构时连接管20的长度。在本申请的其它实施例中，也可能增压器10的空气出口14高于中冷器30的气体通道入口31a，那么，与之相对应的连接管20可以是直线型的结构。
本实施例的中冷器30为水冷中冷器，其位于气缸盖60的上方，通过连接管20与增压器10连接。中冷器30的内部设有气体通道(图未示)和冷却液通道32，本实施例中的气体通道和冷却液通道32的主体部分均为直线型通道，冷却液通道32和气体通道邻接，以通过冷却液冷却气体通道内的气体。在本实施例中，中冷器30相对水平方向向下倾斜一定的角度，该角度范围可以为13.65°-19.65°，使气体通道入口31a的高度高于气体通道出口31b的高度，这样，可使气体通道内不存在低洼部位，使气体通道内因冷却而凝结的水汽能够沿气体通道的内壁面流向节气门50，避免积存在中冷器30内部。
请参阅图3和图4，本实施例的节气门50为扁平式节气门，其压装在中冷器30 和中冷器30下方的进气歧管40之间，通过螺栓等固定件与中冷器30和进气歧管40相连。本申请采用的扁平式节气门的高度低于常规的节气门高度，且节气门50直接与中冷器30和进气歧管40相连，取消了中冷器30和进气歧管40之间的压后管路，如此，可以进一步降低整个装置的高度，使整个装置的结构更加紧凑。
请参阅图5和图6，本实施例的进气歧管40位于发动机气缸盖60的上方，与发动机气缸盖60的进气口相连。进气歧管40包括靠近中冷器30和节气门50的稳压腔41、以及连接于稳压腔41和气缸的进气口之间的若干进气道42。进入进气歧管40的气体经稳压腔41稳压后经进气道42进入气缸。
需要说明的是，在本实施例中，稳压腔41的高度高于进气道42的高度，稳压腔41的底部为一水平底面，进气道42的主体部分为直线型的结构，并且进气歧管40的进气道42相对气缸的进气口向上倾斜，倾斜角度为22°-28°，这样，可使进气道42内不存在低洼部位，使进气道42内因冷却而凝结的水汽能够沿进气道42的内壁面流向气缸，避免积存在进气歧管40内部。
由上面的叙述可以得知，本申请通过将中冷器30和进气歧管40设于气缸盖60的上方，使中冷器30和进气歧管40之间的高度差减小，使整个装置形成为扁平式结构，减小了整个装置的占用空间，并可减小元件之间连接管路的长度，使整个装置的结构更加紧凑，有利于增压响应速度的提升及成本的降低；并且，本申请通过将节气门50压装于中冷器30和进气歧管40之间，并采用扁平式节气门，可以进一步增加整个装置的紧凑性；进一步的，本申请通过将中冷器30和进气歧管40在高度方向倾斜设置，可以使中冷器30的气体通道入口31a和气体通道出口31b、以及进气歧管40的进气道42两端形成高度差，因而能够使中冷器30和进气歧管40内的凝结水汽从高处往低流，避免水汽积存而腐蚀相关元件。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，除了包含所列的那些要素，而且还可包含没有明确列出的其他要素。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保 护范围为准。
