Title:
LASER COOLING HEAT SINK HAVING MICRO-CHANNEL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/032028
Kind Code:
A1
Abstract:
A laser cooling heat sink having a micro-channel structure, comprising a micro-channel heat sink working end (1), a heat-conducting metal filling layer (4), a micro-channel heat dissipation reinforcing end (2), and a heat sink base (3). The micro-channel heat sink working end (1) and the micro-channel heat dissipation reinforcing end (2) are sequentially arranged in the heat sink base (3). The working surface of the micro-channel heat sink working end (1) is attached to the cooling surface of a laser crystal. The heat dissipation surface of the micro-channel heat sink working end (1) is provided with a micro-channel structure, and is connected, by means of the heat-conducting metal filling layer (4), to the micro-channel heat dissipation reinforcing end (2) also provided with a micro-channel structure. The micro-channel structure is formed by pressing staggered heat dissipation ribs (5, 6). The heat sink base (3) is provided with a liquid inlet hole and a liquid outlet hole which are communicated with the micro-channel structure. The heat dissipation ribs (5, 6) arranged in a staggered manner are mutually pressed to form a micro-channel structure, so that the processing controllability is higher, and the processing difficulty is greatly reduced, thereby greatly reducing the precision requirements on processing equipment and reducing the production cost.
