A lubricating device of a reciprocating compressor includes a pumping unit for pumping lubrication oil contained in a lower portion of a case and a front frame having a supply hole which supplies the lubrication oil pumped from the pumping unit to a sliding part within the case and a discharge hole which discharges the lubrication oil upon completion of a lubrication operation. A lubrication oil storage is arranged at a front of the discharge hole for storing the lubrication oil discharged to the discharge hole for a predetermined time and then discharging the lubrication oil. A lubrication oil guide is provided for guiding the lubrication oil discharged from the discharge hole to a lower portion of the case in order to prevent the lubrication oil discharged through the discharge hole from flowing to an air hole formed at a front frame. In the device, lubrication oil is discharged after foam generated by mixture between lubrication oil and a working fluid is burst in the lubrication oil, thereby reducing noise generated when the foam is burst.

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.
