本发明涉及冷却系统中冷却介质的供给方法，具体涉及一种低压油路进油供给结构。
背景技术
数据中心内使用的各类服务器、刀片机等，受大数据业务及市场的带动，其功率大幅度提升，排布密度越来越高；相应的，高热流密度下的散热问题备受关注，也成为数据中心建设及其运维工作的重点和技术瓶颈；间接或直接液冷散热模式由于其综合换热效率高，被认为是数据中心散热的必然趋势；特别的，鉴于热源直接接触吸热、液冷综合换热系数高、传热热阻非常小的优点，直接液冷散热模式从理论上分析是最有效的散热方式。
传统机柜大多采用风冷散热的方式，制冷量有限，如果机柜中设备的放置密度增加，设备的内部温度会急剧上升，不能有效的制冷。另外，传统机柜是开放结构，IP等级低，存在局部紊流和散热死角，散热效率低，能耗高。
现有技术不成熟，在工程化应用实践中，液冷的关键环节之一为供液系统，如何提高供液效率，同时降低供给循环系统的能耗，是解决工程应用的关键。一方面，散热系统要维持正常工作，供液系统需要配备液体泵提供泵功以及备压。散热系统中，泵结构及泵消耗将占据系统一大部分硬件配备和软件控制，如果能减少泵的用量，特别是高压泵的使用，将会大幅度提升此类散热系统的综合能效，同时降低工程成本和运维成本。如果此过程中泵的功率消耗过大，将增加散热系统的总功耗，从而降低散热系统效能(COP)以及数据中心总体PUE，降低节能环保效果。另一方面，机柜内的服务器通常从上至下层层累加摆放。如果供液接口为各层服务器提供循环液的过程中存在不同程度的压损，由于供液量不同、散热温度不同、散热效率不同，严重影响各层服务器的散热效果。
