Disclosed are a reciprocating motor and a reciprocating compressor having the same. The reciprocating motor comprises: an outer stator; an inner stator arranged at an inner circumferential surface of the outer stator with an air gap and at which a winding coil is wound; and a magnet arranged between the outer stator and the inner stator and linearly-moved when a power is applied to the winding coil. The winding coil is installed at the inner stator thus to reduce a usage amount of the coil, thereby reducing a fabrication cost of a motor. Also, a resistance of the coil is reduced thereby to enhance an efficiency of the motor.

In a cooling system for an integrated circuit chip, by including an evaporator contacted-combined with an integrated circuit chip installed onto a board and absorbing heat generated at the integrated circuit chip; a compressor connected to the evaporator by a first connection pipe; a condenser connected to the compressor by a second connection pipe; an expansion means connected to the condenser by a third connection pipe and simultaneously connected to the evaporator by a fourth connection pipe; and a mounting board installed onto the board by a board combining means and mounted with the compressor, the condenser and the expansion means, it is possible to perform the operation of the integrated circuit chip smoothly, and accordingly a reliability of a product can be improved. In addition, although an integrated circuit chip is getting even more integrated, cooling of the integrated circuit chip can be efficiently performed.

A structure for coupling a muffler for a linear compressor is disclosed. The structure includes a muffler including a hallow cylindrical inlet portion, and a contact portion having a predetermined area wherein one end of the inlet portion is outwardly and vertically curved, whereby one end of the inlet portion is inserted into a gas flow path of a piston, and one end of the contact portion contacts with an inner surface of the cover, and an elastic support member disposed between an inner surface of the cover and a side surface of an inner lamination for supporting one end of the muffler, for thereby stably fixing the muffler to the piston without using an additional coupling member.
