Description

一种风力发电机机舱用板式冷却器
技术领域
本发明涉及冷却器，特别是一种用于风力发电机机舱冷却器的结构新设计。
背景技术
传统的板式冷却器由许多相互接触的波形或凹凸形金属板组成，每块板都有4个开口作为流体交换的进出口，每块板的四周有凹槽用来安置模制密封垫片，冷却器的密封性依靠框架组件的紧固实现。两种流体流经相邻板片所构成的流道时进行热量交换，从而达到换热的目的。此种冷却器采用了框架夹紧装置，不易根据负荷变化大范围调整冷却器的容量。由于采用橡胶密封件密封结构，与空气接触日久会发生老化而影响密封性，致使换热效率低。由于橡胶密封件易老化，有维修周期，使用也不方便。
发明内容
本发明的目的是提供具有易安装，免维护，换热效率高的风力发电机机舱用冷却器。
本发明所述的风力发电机机舱用冷却器包括由薄板组成的芯体、边框和侧壁，薄板上有模压成相互垂直且不交叉的凹、凸槽，使薄板旋转90°后其上的槽正好与另一薄板片上的槽形成背靠背或背对背，薄板间形成流道；薄板的一组对边制成雄扣子后再折弯，使雄扣子与同面的凸槽底部在同一平面，薄板的另一组对边反方向制成雌扣子后也折弯，使雌扣子与雄扣子的配合口与同面的凸槽底部在同一平面；依次将每个制作好的薄板的雄扣子与雌扣子，采用推插的方法扣在一起为一组，然后再用专用工具将插扣滚压加工，使雌、雄扣子的联接缝隙闭合，用密封剂将滚压后的扣子缝隙进一步封装，使扣子完全密封，雌、雄扣子扣在一起后使薄板之间的距离正好为要求的设计间隙；若干组扣压好的薄板制得冷却器芯体，冷却器芯体再与边框接合在一起，并用密封剂浇注接合空隙，制得冷却器。
由于相临薄板间均旋转90°后进行联接，构成的相临通道均成90°，这样就构成了具有交错通道的风力发电机机舱用冷却器的芯体。冷热气体分别通过垂直90°的通道时进行热交换，使冷的气体变热，热的气体变冷。采用扣、压及密封剂封装结构密封效果好，可靠性高，免维护，使相邻通道的两路气体不会产生混合。由于用薄板制成的芯体间距精确，制得的冷却器的外形尺寸一样，有利于根据需要可制造多个冷却器单元，进行串联或并联；高强度铝合金型材作为风力发电机机舱用冷却器的边框，分别将冷却器芯体交错通道处的四个边角与边框接合在一起，然后用密封剂浇注密封，使边框两边的气体隔绝，风力发电机机舱用冷却器的机械强度也大大增强。两侧壁用螺钉固定在边框的端头上，侧壁与边框结合处及与冷却器芯体侧面贴合处都用密封剂密封，确保可靠性、免维护。具有安装方便、换热效率高且重量轻，成本低，无交叉污染，密封性能好等特点。

具体实施方式
如附图所示，本发明所述的风力发电机机舱用冷却器包括由薄板2组成的芯体、边框1和侧壁3，薄板2上有模压成相互垂直且不交叉、又分布对称的凹、凸槽6，槽的形状一般为短半圆槽，将薄板旋转90°后的凹、凸槽正好与另一薄板片上的槽形成背靠背或背对背，薄板间形成流道；薄板的一组对边制成雄扣子5后再折弯，一般弯成45°，使雄扣子与同面的凸槽底部在同一平面，薄板的另一组对边反方向制成雌扣子4后也折弯，使雌扣子与雄扣子的配合口与同面的凸槽底部在同一平面；薄板的材料以铝材为好，可减轻冷却器整体重量。如图1所示，依次将每个模制好的薄板扣在一起再将扣合处滚压加工，连成一个整体，然后用树脂密封剂将滚压缝隙封装，构成具有交错通道的风力发电机机舱用冷却器的芯体；用高强度铝合金型材作为风力发电机机舱用冷却器的边框1，分别将冷却器芯体交错通道处的四个边角与边框接合在一起，然后用树脂密封剂浇注接缝密封，使边框两边的气体隔绝，风力发电机机舱用冷却器的机械强度也大大增强。冷却器的两侧壁3用螺钉固定在边框的端头上，侧壁与边框结合处及与冷却器芯体侧面贴合处都用树脂密封剂密封。
由于薄板间距精确，因此制得的冷却器的外形尺寸一样，有利于根据需要可制造多个冷却器单元，进行串联或并联，组合成不同冷却容量的风力发电机机舱用冷却器，一般冷却容量的由80片薄板组成冷却器芯体。
