Description

technical field [0001] The invention designs a cooling device for cooling a heat source with a high heat flux density, and in particular relates to a spray cooling system with a configuration characteristic transmission pipeline spray cooler. Background technique [0002] Although traditional heat dissipation methods such as natural convection and forced convection are widely used, if a heat source with high heat flux density is encountered, the traditional heat dissipation method cannot effectively cool it in a short time. Therefore, better cooling methods must be found to solve this problem. [0003] The spray cooling system uses the principle of phase change after the coolant absorbs heat to enhance heat dissipation. Due to the extremely high latent heat of liquid vaporization, it is suitable for use in heat dissipation systems with high heat flux heat sources. At present, the spray cooling system has been successfully used in aerospace, high-power electronic systems, h...
