A cooling system without a condenser is provided to prevent a refrigerant from overheating while compressing the refrigerant by connecting expansion valves to a compressor with bypass lines and bypassing some of liquid refrigerant to the compressor directly for liquefying the gas refrigerant that is discharged from the evaporators. A cooling system without a condenser comprises first and second extrusion members(110,120), a power applying unit(130), first and second expansion valves(140,150), first and second evaporators(160,170), and first and second bypass lines(L30,L40). The first evaporator vaporizes a liquid refrigerant, which is pressure-dropped in the first expansion valve, and moves it to the second extrusion member. The second evaporator vaporizes the liquid refrigerant, which is pressure-dropped in the second expansion valve, and sends it to the first extrusion member. The first bypass line connects the first expansion valve to the second extrusion member and bypasses some of liquid refrigerant to the second extrusion member directly to liquefy the gas refrigerant that is discharged from the first evaporator. The second bypass line connects the second expansion valve to the first extrusion member and bypasses some of liquid refrigerant to the first extrusion member directly to liquefy gas refrigerant that is discharged from the second evaporator.
