A vapor compression type freezing device using a vortex tube is provided to reduce a manufacturing cost by reducing the size of an outdoor unit and to improve energy efficiency. A vapor compression type freezing device comprises an evaporator(10), a compressor(20), a condenser(30), a throttle device, a tubular vortex generating chamber, an inlet, a passage, a cold air discharging port, and a vortex tube(100). The inlet passes the compressed refrigerant to tangent direction of an inner wall of the vertex generating chamber. One end of the passage is connected to the vortex generating chamber and the other end is closed. The cold air discharging port is formed at one part of the vortex generating chamber and faced to the passage. The vortex tub has a plurality of radiation fins protruded from an outer wall of the passage.
