In recent years, as the diet has become westernized, obesity has rapidly increased, leading to the greatest harm to public health and beauty. Various dietary programs and ultrasonic obesity treatment apparatuses have been developed and widely used for treating this problem.

High Intensity Focused Ultrasound (HIFU) is a non-invasive method for the treatment of cancer cells by selectively coagulating the internal organs and destroying cancer cells. However, in the United States, (Liposonix) equipped with HIFU for the first time. The process of fat destruction using high intensity focused ultrasound (HIFU) is that when the ultrasound is focused at a certain point in the adipose tissue, the tissue temperature instantaneously rises from 65 ° C to 100 ° C, causing tissue destruction. Unlike other dermatological equipment, such as laser and RF high frequency equipment, the HIFU equipment concentrates HIFU energy on non-invasively selected areas without causing any damage to the skin surface to induce coagulation necrosis do. These necrotic adipocytes are naturally removed by our body's repair mechanism.

On the other hand, in the case of a laser device or a high-frequency device, since a heat is generated when a laser or a high-frequency wave is generated, a cooling device for dissipating the heat is used. That is, in the 'medical irradiator for controlling the temperature of the high power laser diode and the contact tip' disclosed in Korean Patent Laid-Open Publication No. 10-2012-0073070, a Peltier device is attached to four surfaces of the aluminum contact tip to cool the contact chip . A laser irradiation unit having a skin contact cooling system disclosed in Japanese Laid-Open Patent Publication No. 10-2013-0097308 discloses a laser irradiation unit having a skin contactor for cooling the skin by contacting the affected part of the patient. The 'skin cooling handpiece' disclosed in the publication No. 10-2015-0026704 discloses a skin cooling handpiece which changes the state of cooling gas injection according to the laser output state.
