What is a heat pipe radiator?

Heat pipe radiator is a new product that can make significant improvements to many old radiator or heat exchange products and systems by using heat pipe technology. Heat pipe radiators have two categories: natural cooling and forced air cooling. The thermal resistance of air-cooled heat pipe radiator can be made smaller, which is often used in high-power power supply. What is a heat pipe radiator?

The fan in the laptop takes away heat through the heat pipe radiator + air flow. Today, let’s start with the heat dissipation of notebook computers.

When you press the start button, all components on the computer will be powered on and start working. At the same time, it will inevitably start heating. Among them, CPU and GPU generate the most heat due to the most computing tasks, up to more than 100 ℃.

The heat accumulated on the chip will not only affect the performance and stability of computer operation, but also shorten the service life. Heat dissipation equipment must be installed.

For desktop computers, as long as they are assembled by themselves, it is generally known that there are one or more large fans on the CPU. However, due to the small space and moderate weight of the notebook, it does not affect the portability, so the radiator is generally heat pipe + small fan for heat dissipation.

Generally speaking, when you use it at home or in the office, you will buy a simple and rough cooling base for your laptop. The principle is very simple, which is equivalent to putting an electric fan under your laptop.

But the real effective and direct heat dissipation is the built-in heat pipe radiator in the notebook. After all, it can directly take away the heat of the CPU.

Most of the heat pipes are a sealed hollow copper pipe, and the inner wall is a porous structure, which greatly increases the area of the inner wall. At the same time, it is pumped into a negative pressure state and filled with liquid with low boiling point and easy to vaporize.

When the heat pipe is heated near the CPU end, the liquid in the capillary porous material evaporates rapidly, and the steam flows to one side of the fan under the action of small pressure difference. When it is cold, it condenses and liquefies to release heat, and the fan takes out the heat again; The condensed liquefied liquid flows back along the porous material by capillary action. Continuously take away the heat generated by continuous vaporization and liquefaction.
