The present invention relates to a cooling fat decomposition apparatus for removing a bruise, and more particularly, to a cooling fat decomposition apparatus for removing a bruise, and more particularly, A vacuum suction unit provided so as to generate a constant vacuum pressure inside the accommodation space to adsorb a target portion to an inner side wall of the suction space of the suction unit； and a heat exchange plate which is in close contact with the thermoelectric element on the opposite inner wall of the suction unit, A heat exchange unit which is rotatably mounted to cool or heat a target portion adsorbed in the suction space of the suction unit according to a change in polarity of the thermoelectric device, The suction side inner wall surface and the surface of the target site adsorbed into the suction side A driving unit installed at one side of the heat exchange plate to provide a driving force to the rotary shaft so that the heat exchange plate can be rotated at a predetermined angle based on a value sensed by the sensing unit； Wherein the control unit controls the vacuum suction unit to adsorb the target portion with the first vacuum pressure, thereby controlling the operation of the driving unit according to the sensed value of the sensing unit, Cooling the target site for chilling to decompose fat, then controlling the vacuum suction unit to adsorb the target site at a second vacuum pressure lower than the first vacuum pressure, changing the polarity of the thermoelectric device, And a heating means composed of a hot wire coil is further installed at an end of the suction portion Thereby providing heat to the target portion contacting the end portion of the suction portion. According to the present invention as described above, the target area is adsorbed for a certain period of time, and after cooling fat decomposition, heat is applied to the target area to remove the bruise marks generated in the target area, thereby reducing skin damage.
