As a heat dissipation tool with high efficiency, aluminum radiator profiles are widely used in electronics, electrical appliances, lighting and other industries. Different manufacturers have different technologies and refer to different production standards. There are advantages and disadvantages of the aluminum radiator profiles produced in terms of heat dissipation effect. What are the factors that affect the heat dissipation effect?
Radiator bottom design
Generally people think that a piece of fin is the key to heat dissipation, in fact, the bottom of the heat sink is also a part of the heat dissipation can not be ignored. The design of the bottom of the aluminum radiator profiles should adhere to the principle of gradually thinning from the heat source part to both sides. This is to guarantee that the fever absorbed by the fever source part can be quickly transferred to the surrounding thinner part to achieve high efficiency fever dissipation. Otherwise, the heat of the heat source can not spread around rapidly, which will affect the radiator to further absorb heat from the heat source.
Radiator fin design
The fins were designed to increase the area of contact with the heat source to absorb more heat, but also to increase the area of contact with the air to disperse heat into the air more quickly. One might wonder if the thicker the fins, the better the heat dissipation? In fact, the overall area of the radiator is limited, the more fins, it is true that there is a larger contact area to absorb more heat, but this also means that the spacing between the fins becomes smaller, at this time the speed of air flow in each channel, the radiator to disperse heat into the air becomes more difficult. As fins get thicker, the number of fins decreases, and heat absorption doesn't necessarily increase. Therefore, when producing aluminum radiator profiles, the design of fins should be calculated reasonably and precisely according to the requirements, and produced in strict accordance with the planning. Only in this way can the finished product fully meet the heat dissipation requirements.
