“…The simulation calculation process does not consider radiation heat transfer and adopts turbulence method. The control equation adopts the standard k-ε Realizable two equation model, and the thermal conductive silicone grease applied between the heat source device, the heat sink has a contact thermal impedance of 0.0001   2 / C m W   [25][26] . The device parameter setting are shown in Table 3 In the case of a heat sink size of 60mm * 20mm * 15mm, the dual fans effectively cooled and dissipated heat for the heating units of heat source groups 3 and 4, and the farthest temperature of the laser chip was around 35.1 C  .…”

Blue semiconductor lasers have broad application prospects in fields such as material processing, underwater communication, and ocean exploration due to their unique wavelength advantages. At present, the power of blue light single tube LDs is relatively low. By using incoherent laser beam combining technology and fiber coupling technology, multiple blue light LDs can be synthesized into a high-power and high uniformity laser, meeting a wider range of application needs. This article designs a 100W level blue light LD fiber coupling module, which uses 32 single tubes with a power of 5W LDs. Through spatial and polarization beam combining design, it is focused and coupled into 105 μm/NA0.22 optical fiber. After simulation with Zemax software, a 138.7 W high brightness blue laser was obtained, with a fiber coupling efficiency of 91.48%. A dual axial flow fan air-cooled heat dissipation structure has been designed. After simulation with Ansys Icepak software, the maximum temperature of the laser module is 35.1 ℃, and it can continuously output light for operation.

“…The working principle of the vapor chamber is shown in Figure 1. The thermal resistance of the commonly used vapor chamber could be less than 0.5K/W, and the heat of the laser diode can be rapidly distributed laterally [6] . After using the vapor chamber, the heat dissipation area is increased, and multiple TECs can be closely attached under the vapor chamber to take away the output heat of the vapor chamber, thereby improving the cooling capacity of the system.…”

This paper proposes a multi-stage cooling system based on TEC (Thermo Electric Cooler), vapor chamber, heat sink and fan for the high power compact laser diode in the high temperature and mobility environment. Using Flow Simulation and ANSYS software, the temperature field and thermal stress of the multi-stage cooling system under steady state are discussed respectively, and the multi-stage cooling system model is optimized according to the two simulation results and the physical test is carried out. The results show that the designed cooling system can achieve a continuous and stable output of more than 70W from the laser at both room temperature of 20°C and high temperature of 55°C.
