Linear compressor

The utility model relates to a linear compressor, which comprises an air cylinder, a piston and a piston rod, a piston that reciprocates in the axial direction within the cylinder; a mover coupled tothe piston to transmit a driving force to the piston and reciprocate in an axial direction; a stator having a cylinder space into which the cylinder is inserted and generating a driving force togetherwith the mover; and a support unit having a radially overlapping portion that at least partially radially overlaps the stator, the radially overlapping portion being coupled to the stator in a contact manner, thereby being capable of quickly radiating heat transferred through the motor. 本实用新型涉及一种线性压缩机，包括：气缸，其具有用于压缩制冷剂的压缩机空间；活塞，其在气缸内在轴向方向上进行往复运动；动子，其联接到活塞，以向活塞传递驱动力并在轴向方向上进行往复运动；定子，其具有供气缸插入其中的气缸空间，并且与动子一起产生驱动力；和支撑单元，其具有至少部分地与定子径向重叠的径向重叠部分，所述径向重叠部分以接触的方式被联接到定子，由此能够快速地辐射通过马达传递的热量。
