Loop heatpipe technology application in thermal solution
With the rapid development of the electronic industry, electronic components have been widely used in many key fields, and are developing towards high operation speed, miniaturization and compactness, and their heat flux is higher and higher. Therefore, it is of great significance to research and develop electronic heat dissipation devices with compact structure, reliable performance, flexible and convenient installation, high heat dissipation efficiency and easy maintenance.
Loop heat pipe (LHP) is an efficient heat transfer device. It drives the flow of working fluid through the capillary force generated by the suction core in the evaporator, and uses the phase change process of working fluid to transfer the heat pipe efficiently. Compared with other traditional heat pipes, its biggest advantage is large heat transfer distance and anti gravity operation.
A typical loop heat pipe consists of evaporator, condenser, liquid reservoir, steam pipeline and liquid pipeline, which drives fluid circulation and long-distance directional heat transfer by capillary force.
loop heat pipe has the advantages of large heat transfer distance, compact structure, strong heat dissipation capacity, strong anti gravity, good heat balance and convenient installation and layout. It has been widely used in the fields of electronic cooling, battery thermal management, high-power LED, waste heat recovery, aerospace and military equipment.
In recent years, with the 5G technology promoting high heat flux electronic equipment heat dissipation facing major challenges, the development potential of loop heat pipe in the field of electronic heat dissipation has been fully tapped, and its application scope and depth are rapidly improving.
