1. A beauty care apparatus comprising:
a housing part configured to accommodate a medium therein and formed of a thermally conductive material;
a holder part disposed inside the housing part, and including a holder body part having a flat part formed on an outer side surface;
an ultrasonic wave generator configured to be coupled to the holder part and generate ultrasonic waves; and
a cooler installed in the housing part to cool the housing part,
wherein the housing part includes:
a housing body part configured to accommodate the holder part;
a housing cover part configured to be coupled to the housing body part and configured to be irradiated with ultrasonic waves generated from the ultrasonic wave generator; and
a heat conductor connected to the housing body part and the cooler to cool the housing body part,
wherein the heat conductor includes:
a contact panel part configured to come in contact with the cooler; and
a heat conduction panel part configured to extend from the contact panel part to come in contact with an outer side surface of the housing body part
wherein:
a flat part is formed on the outer side surface of the housing body part; and
a flat heat conduction surface part is formed on the heat conduction panel part to come in contact with the flat part of the housing body part,
wherein the cooler is a plurality of Peltier elements disposed in a peripheral direction of the housing part at one side of the housing part,
further comprising a heat dissipation unit configured to come in contact with a heat generation surface part of each of the plurality of Peltier elements so that heat is dissipated from the heat generation surface part,
wherein the flat part of the holder body part contacts an inner side surface of the housing body part, and the flat part of the housing body part contacts the flat heat conduction surface part, and
wherein the heat dissipation unit is interposed between the plurality of Peltier elements, and the plurality of Peltier elements are arranged facing each other.
