Introduction to finned heat sinks
The finned heat sink primarily achieves heat dissipation through conduction, involving a medium heat sink that is in direct contact with the processor. After absorbing heat, the heat sink dissipates it through convection. In the convection heat dissipation process, the heat dissipation area is mainly determined by the surface area of the heat dissipation fins. The larger the surface area, the better the heat dissipation effect. The smaller the surface area, the worse the heat dissipation effect.

Knowledge related to finned heat exchangers
The characteristics of finned heat sinks are that the fins break through the original proportional limitations, resulting in good heat dissipation, and they can also be made from different materials. Of course, the drawbacks are also quite obvious, as the interface resistance issue caused by the thermal paste and solder bonding between the heat sink and the base can affect heat dissipation. To improve these shortcomings, two new technologies have been applied in the field of heat sinks.

Characteristics of finned heat sinks
The finned heat sink is a device used to dissipate heat from electronic components that are prone to heating in electrical appliances. It is made of aluminum alloy, brass, or bronze and comes in plate, sheet, or multi-plate forms. For example, the CPU in a computer requires a relatively large heat sink, while the power tubes, line tubes, and amplifier tubes in a television also need heat sinks. Generally, when in use, a layer of thermal grease should be applied to the contact surface between the electronic components and the heat sink to more effectively transfer the heat generated by the components to the heat sink, which then dissipates it into the surrounding air.

What are the advantages of heat pipe module coolers?
Heat pipe module radiators are widely used in various industries and have a broad range of applications. The heat pipe module radiator has the advantage of very fast heat transfer. Installing it in a radiator can effectively reduce thermal resistance and improve cooling efficiency. The heat pipe, also known as a 'thermal superconductor', has the core function of conducting heat. In fact, it transmits heat through the phase change of the working fluid inside a fully sealed vacuum tube during operation.

Introduction to the principle of heat pipe module coolers
The heat pipe module cooler consists of a sealed tube, a liquid-absorbing core, and a vapor channel. The liquid-absorbing core is actually wrapped around the wall of the sealed tube and is soaked with a volatile saturated liquid. If it is to be used, it is important to know that this liquid can be distilled water, ammonia, methanol, etc. Heat pipe coolers filled with liquids such as ammonia and methanol still have excellent cooling capabilities at low temperatures.

Basic knowledge of heat pipe module coolers
Before using heat pipe module coolers, there are many questions that come up, so to use them better, it's important to understand the relevant knowledge. First, it's essential to know that a heat pipe module cooler is a component with an extremely high thermal conductivity. The heat pipe transfers heat by relying on the cycle of absorbing and releasing vaporization latent heat when a liquid medium is added in a vacuum. Because the latent heat of vaporization of the medium is very large, its thermal resistance is extremely low, which results in the heat pipe having an extremely high thermal conductivity.
