Description

Radiator with high radiating efficiency

Technical Field

Background

In air-cooled systems and other radiator systems, the blower mechanism and the heat sink are important components. The blowing mechanism is used for increasing the flowing speed of air near the object to be cooled, and the radiating fins are used for increasing the contact area between the air and the object to be cooled so as to improve the heat radiation rate.

The conventional heat sink has a lower limit of the total thickness of the heat sink determined by strength factors and heat dissipation factors. 1) The thickness of the individual fins must be higher than the lower break-off limit because if the thickness of the individual fins is lower than the lower break-off limit, the fins become easily broken; 2) the thickness of the gap between two adjacent fins cannot be lower than the lower limit of the heat dissipation gap because if the thickness of the gap between two adjacent fins is lower than the lower limit of the heat dissipation gap, the heat dissipated by the fins is accumulated in the gap between the fins, and cannot be quickly transferred out of the gap.

Therefore, the conventional heat sink is generally configured to have a rectangular cross section in order to take both of the above two factors into consideration, and the heat sink having the rectangular cross section cannot maximize the heat dissipation rate.
