COOLING STRUCTURE OF A LINEAR COMPRESSOR FOR COOLING A LINEAR MOTOR BY CIRCULATING OIL FOR LUBRICATING OR COOLING A PISTON AND A CYLINDER AROUND A COIL

摘要

PURPOSE: A cooling structure of a linear compressor is provided to prevent lowering of efficiency of the linear compressor or reduction of the life span from overheat of the coil by cooling the bobbin or the coil with the cooling fluid, and to cool the linear motor efficiently and quickly by arranging the radiating pipes spirally in the inner periphery or the outer periphery of the bobbin. CONSTITUTION: A cooling structure of a linear compressor comprises a bobbin(133), a coil(134) winding on the bobbin, a magnet(135) linearly reciprocating from interaction with the magnetic field formed around the coil, a piston(144) reciprocating linearly and interlocking with the magnet, a cylinder(109) having a compression chamber in which the piston reciprocates, a radiating pipe(160) contacted to the bobbin, and a cooling fluid supply unit feeding cooling fluid to the radiating pipe. The radiating pipes are arranged spirally and contacted to the linear motor.
