Abstract

Instalatia de racire pentru laseri cu mediu activ solid si frecventa mare de repetitie, conform prezentei inventii, asigura disiparea caldurii reziduale din zona capului laser, prin intermediul unui lichid de racire, antrenat de o pompa centrifugala spre un schimbator de caldura de tipul lichid-lichid. în schimbatorul de caldura, lichidul de racire circula printr-o serpentina, cedând caldura unui lichid volatil, care, fiind fortat sa se vaporizeze, o elimina în mediul extern sub forma de caldura latenta de vaporizare. Sistemul realizat sub forma portabila permite disiparea unei puteri de 200-300 W, cu functionare intermediara sau continua, timp de o ora fara a fi reîncarcat cu lichid volatil. Lichidul volatil este netoxic si neinflamabil. Sistemul asigura o racire eficienta a capului laser la frecventa de repetitie peste 15 Hz, pe un interval de temperatura a mediului ambiant de la 40 degree C la 60 degree C.The solid-state and high frequency rehearsing active cooling lasers of the present invention provide residual heat dissipation from the laser head area by means of a coolant driven by a centrifugal pump to a liquid-liquid heat exchanger . In the heat exchanger, the coolant circulates through a coil, releasing the heat of a volatile liquid which, being forced to vaporize, removes it in the external environment in the form of latent heat of vaporization. The portable system allows 200-300 watts power dissipation with intermediate or continuous operation for an hour without recharging with volatile liquid. Volatile fluid is nontoxic and non-flammable. The system ensures an efficient cooling of the laser head at a repetition frequency of more than 15 Hz over an ambient temperature range from 40 degrees C to 60 degrees Celsius.
