Abstract

The invention provides a large-channel semiconductor laser liquid refrigeration sheet and a semiconductor laser stack array employing the liquid refrigeration sheet. The large-channel semiconductor laser liquid refrigeration sheet comprises a refrigeration sheet main body provided with a liquid-inlet hole and a liquid-outlet hole, and a tubular liquid refrigeration channel used for communicating the liquid-inlet hole and the liquid-outlet hole is arranged in the refrigeration sheet main body. According to the large-channel semiconductor laser liquid refrigeration sheet, the liquid refrigeration channel is not easily blocked, the reliability of the device is improved, the lifetime of the device is prolonged, and the heat radiation effect of the large-channel refrigeration sheet is equivalent to that of a micro-channel refrigeration sheet in the same flow condition; and compared with the conventional macro-channel liquid refrigeration sheet, according to the large-channel liquid refrigeration sheet, the refrigeration area is increased, the thermal conduction path is shortened, and the heat radiation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of semiconductor lasers, and in particular relates to a large-channel semiconductor laser liquid cooling chip and a semiconductor laser stack using the liquid cooling chip. Background technique [0002] Semiconductor lasers have the advantages of small size, light weight, high reliability, long service life, and low cost. They have been widely used in various fields of the national economy, such as laser pumping, medical treatment, and industrial processing. [0003] In the prior art, the packaging forms of power electronic devices include conduction cooling type, micro-channel liquid cooling type and macro-channel liquid cooling type (200910023753.3). For high-power semiconductor lasers, conduction cooling is used, and the heat dissipation efficiency is low, which will lead to a decrease in device life and reliability, and generally can only reach an output power of tens of watts; if micro-channel liquid co...
