Embedded cooling assembly and standby device

The invention provides an embedded cooling assembly which comprises a weldment and a screw set, the weldment comprises a first assembly and a second assembly, the second assembly is inserted into a cutting arm shell through the screw set, and the surface of the first assembly is in radial spigot fit with the corresponding position of the cutting arm shell; the two ends of the first assembly are opened respectively to form a first through hole and a second through hole, and the two ends of the first cavity in the second assembly are connected with the first through hole and the second through hole respectively. After the embedded cooling assembly is completely embedded into the cutting arm shell, the first through hole and the second through hole are attached to a water path on the cutting arm shell, the structure is compact, the occupied space is small, and reliability is high. 本发明提供一种嵌入式冷却组件，包括焊件和螺钉组，其中，焊件包括第一组件和第二组件，第二组件通过螺钉组插入截割臂壳体，第一组件的表面与截割臂壳体的相应位置径向止口配合；第一组件的两端分别开口，形成第一通孔和第二通孔，第二组件中的第一空腔的两端分别连接第一通孔和第二通孔
