具体实施方式
为详细说明本发明的技术内容、所实现目的及效果，以下结合实施例并配合附图予以说明。
实施方式1:
一种集成式机油冷却滤清结构，包括冷却滤清壳体1和冷却器芯2，冷却器芯2设置在冷却滤清壳体1的底部，所述的冷却滤清壳体的一侧集成设有同轴布置的离心式机油滤清器3和纸质机油滤清器4，所述的冷却滤清壳体1内设有可将冷却液分别引向所述冷却器芯2和机体缸盖内的第一分流结构5；所述的冷却滤清壳体1另一侧设有可与水泵相连的水泵蜗壳6模块，与第一分流结构5连通，所述的冷却滤清壳体1底部靠近所述水泵蜗壳6模块的一侧设有安装张紧轮的张紧轮支架7，张紧轮可用于调节皮带张紧度。
工作原理：机油的油路是从机油泵输出的机油从机油入口11流入集成式机油冷却滤清结构，流入同轴布置的离心式机油滤清器3和纸质机油滤清器4，经离心式机油滤清器3过滤后的机油，再流入油底壳，再与机油泵相连通形成回油油道。经纸质机油滤清器4过滤后的机油，再流入冷却器芯2最后流入机油出口12，进入机油主油道。冷却液的流道是：水箱散热器中的冷却液经水泵蜗壳，流入第一分流结构5，分成两股冷却液，一股流向机体缸盖，对机体缸盖进行冷却，一股流向冷却器芯2对机油进行冷却。冷却后的冷却液流回水箱散热器，完成循环。此种冷却液并联循环相对于串联循环，在整个冷却液循环过程中冷却***的阻力小。***阻力小，意味着冷却***对水泵的扬程需求就小，水泵所消耗的功耗小，有利于降低发动机油耗。
此外，所述纸质机油滤清器4和离心式机油滤清器3作用是过滤机油中的杂质，保证零件不被磨损，延长机油使用寿命。张紧轮支架7作用是固定前端皮带轮系中的张紧轮。冷却器芯2是冷却液与机油热交换的场所，用于机油降温。水泵蜗壳6是将水泵叶轮封闭的空间,以便由叶轮的作用吸入和压出冷却液。冷却滤清壳体的作用是支撑并承载各个子零件。
本集成式机油冷却滤清结构采用集成式设计，能节约零件的布置空间。同时相比于单独的零件，集成式的设计能有效降低重量。同时集成化设计减少了密封件的使用，能改善密封。
实施方式2:
在实施方式1的基础上，所述一种集成式机油冷却滤清结构，还包括单向阀8，所述单向阀8设置在机油入口11，机油入口11通过第二分流结构9分别连接离心式机油滤清器3和纸质机油滤清器4。单向阀8的作用是为了防止停机后机油回流，以免发动机重新启动时机油需要重新填充模块，减少内部件的干摩擦。
实施方式3:
在实施方式1的基础上，所述一种集成式机油冷却滤清结构，还包括机油温控阀10，所述经纸质机油滤清器4过滤后的机油通过机油温控阀10分别连通冷却器芯2和机油入口12。机油温控阀10的作用是精确控制机油温度，当机油温度低时，控制机油不经过机油冷却器芯2，当机油温度升高后，控制机油进入机油冷却器芯2，使机油降温，让机油温度保持在合理的范围。
虽然，上文中已经用具体实施方式，对本发明作了详尽的描述，但在本发明基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本发明精神的基础上所做的这些修改或改进，均属于本发明要求保护的范围。
