1. A linear compressor comprising:
- a cylinder;
a piston disposed such that the piston can be linearly reciprocated in the cylinder;
a bobbin;
a coil wound on the bobbin;
a magnet linearly movable by means of a magnetic force generated around the coil;
a magnet frame to transmit the linear movement of the magnet to the piston;
a cooling channel disposed in contact with the bobbin; and
a cooling fluid supply unit to supply a cooling fluid into the cooling channel.

Abstract
Disclosed herein is a linear compressor. The linear compressor comprises a cooling channel disposed in contact with a bobbin on which a coil is wound, and a cooling fluid supply unit to supply a cooling fluid to the cooling channel such that the bobbin and the coil are cooled by means of the cooling fluid. Consequently, the coil is prevented from overheating, whereby compression efficiency of the linear compressor is effectively improved, and service life of the linear compressor is effectively increased.

13. A linear compressor comprising:
-
a hermetically sealed container containing oil;
a cylinder block disposed in the hermetically sealed container, the cylinder block being provided with a cylinder;
a piston disposed such that the piston can be linearly reciprocated in the cylinder;
a linear motor connected to the piston for linearly reciprocating the piston, the linear motor including a bobbin having a coil receiving part and an oil receiving part divided from the coil receiving part by means of a partition, a coil wound on the coil receiving part, an outer stator core that surrounds the bobbin, a magnet linearly movable forward and backward by means of a magnetic force generated at the coil, and a magnet frame to transmit the linear forward and backward movement of the magnet to the piston; and
an oil supply unit to supply oil to the oil receiving part of the bobbin. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
