得到制冷剂流量为23 mL/min时的热阻为0.289 ℃/W。

Abstract

Based on the theory of phase change decalescence of throttled cooling medium with high pressure in the micro evaporation cavity

a new pack module was designed for the refrigeration of high power laser diode. Oxygen-free copper with high heat-conducting was adopted in the module. The micro evaporative cooling module was constructed with the process of wire-electrode cutting

chemical corrosion

and welding by the newly designed welding equipment. According to thermal model of high power laser diode

numerical simulation is conducted theoretically on the module

and the result is consistent with the experiment of the heat dissipation of laser bar with the power of 60 W. From the experiment

the thermal resistance is 0.289 ℃/W when the refrigerant flow rate is 23 mL/min.
