The heat pipe radiator mainly relies on convection, and if convection is disrupted, the thermal efficiency will be greatly reduced. Traditional home decoration often involves covering the heating unit without considering the most basic physical principle—thermal convection, which disrupts the normal heating of the heating equipment. Hot air is light, while cold air is heavy; therefore, air conditioning is installed high up to allow cold air to descend from above, while installing it low makes it easier for hot air to rise. Strengthening convection can quickly increase heat, ensuring that heating costs are not wasted.

As a device for conducting and releasing heat, heat pipe radiators play an important role in both home and industrial heating. The development of radiators in our country has gone through more than half a century, especially at the end of the last century and the beginning of this century. Currently, they are widely used in northern regions of China, and with the increasingly unstable global climate, warmer southern regions have also begun to use variable frequency radiators for heating.
Recently, the country has introduced a series of policies to support the development of energy-saving and environmentally friendly industries, which will greatly promote the future development of heat pipe radiators. Especially in the context of booming domestic real estate development, heat pipe radiators will face good development opportunities in the next five years.
Currently, the characteristics of heat pipe radiators in our country are branding, systematization, and simplification.
The brand awareness in the radiator industry is gradually increasing. At the beginning of this century, the state conducted a census of domestic enterprises. According to statistics, there are more than 1,200 manufacturing enterprises in our country, but most are small-scale with low production capacity and poor technical levels. However, after ten years of development, a number of large-scale manufacturers with high production capacity, advanced technology levels, and guaranteed product quality have emerged in the industry. Now, domestic heat pipe radiator manufacturers are gradually enhancing their awareness of establishing independent brands, and the previously chaotic market situation is also gradually improving.
The development of modern science and technology has brought many conveniences to people's lives and industrial production, and people's requirements for scientific systematic management are also increasing. In the application of radiators, not only individuals but also heating work needs to be systematized. As scientific management models for home life and industrial production become more common, heat pipe radiators also require systematic control and management. While continuously improving technical levels, the industry is also developing system control to enhance technological content. The technological level abroad far exceeds that of the domestic radiator industry; these gaps represent the future development direction for domestic variable frequency radiator industry.
To date, heat pipe radiators have evolved from initial cast iron radiators to lightweight radiators. Using non-ferrous metal materials has significantly improved their appearance and quality compared to traditional cast iron radiators. This meets people's demand for an improved quality of life and has gained favor among consumers. In the future, the heat pipe radiator industry will develop towards a simpler direction. It is believed that with the invention and use of new materials, the market will become increasingly broad.

Application fields of heat sinks
As an indispensable part of the thermal management system, radiators have a wide range of applications.
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.
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.
