Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cooling apparatus for a laser irradiation apparatus,

The present invention relates to an apparatus for cooling a cooling water for a laser irradiation apparatus, and more particularly, to an apparatus for cooling a cooling water for a laser irradiation apparatus capable of rapidly and efficiently removing heat generated from a laser irradiation apparatus, The present invention relates to a cooling water cooling apparatus for an apparatus.

The laser irradiator is widely used in various fields. In particular, the Nd: YAG laser irradiator, which is widely used for medical applications, is designed to irradiate a yttrium aluminum garnet crystal treated with 1 to 3% of neodymium ions at high pressure And activated by a flash light discharge tube to irradiate a laser beam having a wavelength belonging to the near infrared region of 1064 nm.

The long pulsed Nd: YAG laser with a wavelength of 1064 nm has a relatively long irradiation time and has a low energy, so it is used for the treatment of blood vessels such as permanent hair removal, facial vasodilation, vein vasodilation, and non-invasive facial skin It is also widely used for reproduction.

On the other hand, the Endianag laser irradiating apparatus uses a known Q-switching device configured to control the distribution inversion energy of the pulses by covering a part of the laser reflector, and transmits a long pulse wavelength band of 1064 nm to the Q- switched laser, that is, a pulse of 1064 nm, into a short pulse band having an extremely short pulse width and a high output energy.

A Q-switched Nd: YAG laser with a 1064 nm wavelength converted to a short pulse with a short pulse width and high output energy is used to treat lesions located deep in the dermis, Line tattoo and so on.

On the other hand, when a wavelength of 1064 nm outputted from a Q-switched Nd: YAG laser is incident on a nonlinear crystal called potassium titanium oxide phosphate (KTiOPO4, KTP), light having a wavelength of 532 nm (a cue- Switch endian laser), which is called a KTP laser or frequency doubled Q-switched Nd: YAG laser.

The wavelength of 532 nm is close to the oxygen absorption wavelength (542 nm) of hemoglobin (oxyhemoglobin), which is effective in the treatment of vascular lesions.

And Long Pulse 532nm Endian Laser is a laser irradiation device using 532nm wavelength which has a high hemoglobin and melanin absorption rate. It is effective for the treatment of blood vessels such as capillary vasodilatation, facial flushing, and vasculature, and epidermal pigment such as spots, It is also widely used because it is effective in various skin diseases and overall skin improvement.

The laser light irradiation device resonates and outputs the light irradiated from the lamp through a medium rod doped with neodymium ions in YAG (Y2Al5O12) crystals.

However, in the laser irradiation apparatus, a large amount of heat is generated in the lamp and the medium rod during the irradiation of the laser light, and the heat generated as described above limits the irradiation time of the laser light through the laser irradiation apparatus.

In addition, since the heat generated as described above is a factor for shortening the service life of the lamp and surrounding structures, cooling of the cooling water in the laser irradiation apparatus is an important problem. Conventionally, devices for cooling the cooling water have a complicated structure, .
