Heat sink + wire buckle - performance of heat pipe module heat sink

Today's high-power LED lights (over 300 watts) mainly use heat pipe module radiators for heat dissipation, but this cooling technology currently faces challenges from the temperature uniformity plates and composite channel cooling technologies inherited from PC processors. Below, we will discuss why Overclocking Technology is so fond of heat pipe cooling technology.
In addition to considering the currently popular heat pipe module radiators for high-power (over 300 watts) outdoor LED lights, one can also consider using temperature uniformity plates and composite channel radiators inherited from PC high-speed processor cooling. The following text will first introduce the working principle and advantages and disadvantages of heat pipe module radiator technology, and then introduce temperature uniformity plates and composite channel cooling technology.
We all know that there are three ways to transfer heat: conduction, convection, and radiation. Any cooling design is a comprehensive application of these methods. Currently, the commonly used cooling methods in the industry are as follows: natural cooling, forced convection cooling, and heat pipe cooling. Heat pipe cooling is currently the most effective and stable cooling device, with a heat conduction speed dozens to hundreds of times higher than traditional metals. This characteristic is excellent for LEDs as it can quickly transfer the heat generated by LEDs to other places in the fastest way possible, which is quicker and more effective than any other method. The downside is that the cost is relatively high; however, if we achieve standardization and modularization of heat pipe cooling, its cost will not be an issue.
So what characteristics does this new technology have?
From a usage perspective, heat pipes have the advantage of extremely fast heat transfer speed. When installed in a radiator, they can effectively reduce thermal resistance and increase cooling efficiency. Heat pipes, also known as 'thermal superconductors', primarily function to conduct heat. They transfer heat through the phase change of the working fluid between gas and liquid within a fully sealed vacuum tube, exhibiting extremely high thermal conductivity—hundreds of times that of pure copper.
From a technical perspective, the core function of a heat pipe is to improve the efficiency of heat transfer by quickly removing heat from the heat source, rather than what is generally referred to as 'heat dissipation'—which includes the process of thermal exchange with the external environment. The working principle of a heat pipe is quite simple; it consists of two parts: the evaporating heated end and the condensing end. When the heated end is heated, the liquid around the pipe wall vaporizes, generating vapor. At this point, the pressure in this section increases, causing the vapor to flow towards the condensing end. Upon reaching the condensing end, it condenses back into liquid while releasing heat, and finally returns to the heated end through capillary action to complete one cycle.
