When usingheat pipe module coolerthere have been many issues accompanying everyone, so to use it better, one must understand the relevant knowledge. First, it is important to know that a heat pipe module cooler is a component with an extremely high thermal conductivity. As long as the heat pipe relies on the cycle of absorbing and releasing vaporization latent heat when liquid medium is added in a vacuum to transfer heat, because the vaporization latent heat of the medium is very large, its thermal resistance is extremely low, thus the thermal conductivity of the heat pipe is extremely high. Generally, the thermal conductivity of copper heat pipes with a diameter of 4-8mm is more than 40 times that of solid copper with the same diameter cross-section. Nowadays, heat pipe module coolers have become a very common thermal conduction device. Although there are many types of heat pipe cooling products, due to cost considerations, heat pipe coolers have not been fully popularized.
Heat pipe module coolers have previously been widely used in industries such as aerospace and military. Since being introduced into the radiator manufacturing industry, this has naturally changed the design thinking of traditional radiators, breaking away from solely relying on large air volume. Using motors to achieve better cooling effects through a single cooling method. Moreover, manufacturers are also very skilled in using heat pipe technology, so even if the heat pipe module cooler uses low-speed and small-sized motors, the noise problem that troubles air-cooled cooling can be well solved, opening up new horizons in the cooling industry. Heat pipes can be made into thermal sensitive diodes or thermal sensitive switches. The so-called thermal sensitive diode only allows heat flow in one direction and does not allow heat flow in the opposite direction; a thermal sensitive switch refers to when the temperature of the heat source exceeds a certain temperature, the heat pipe begins to work. Nowadays, low-end entry-level cooling products with large shipment volumes have made it difficult to find traces of heat pipes. Of course, this also means that most users cannot enjoy the benefits brought by heat pipes, which is a great regret. Due to low-end products having low heat generation and not requiring high cooling performance, coupled with cost issues, it is currently not easy for heat pipe module coolers to be fully popularized.

How much do you know about finned heat sinks?
The characteristics of finned heat sinks are that the fins break through the original proportional limitations, resulting in good heat dissipation effects, and different materials can be used to make the fins. The drawbacks are also quite obvious, as the heat sink and the base are bonded with thermal paste and solder, which can cause interface resistance issues that affect heat dissipation. To improve these shortcomings, two new technologies have been applied in the field of heat sinks.
Introduction to the characteristics of finned heat sinks.
The finned heat sink is a device used for electronic components that are prone to heating in electrical appliances. It is made of aluminum alloy, yellow or bronze, and comes in plate, sheet, or multi-sheet shapes. For example, the CPU in a computer requires a considerable size, and the power tubes, line tubes, and amplifier tubes in televisions all need to dissipate heat. Typically, a layer of thermal grease should be applied to the contact surface of the electronic components to more effectively conduct the heat generated by the components, which is then dissipated into the surrounding air.
Introduction to the advantages of finned heat sinks
The finned heat sink primarily achieves heat dissipation through conduction, involving dielectric heat sinks that are in direct contact with the processor. After absorbing heat, it dissipates through convection. During the convection process, the area is mainly determined by the surface area of the fins. Common methods used in the industry include: increasing the number of fins and increasing the length of the fins. One of the reflected data points is the 'thickness ratio', which is the ratio of fin thickness to its height.

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.
