Straight Fin Heatsinks

Passive LED heatsink assembly

One of the more common types of dispersing a component's thermal energy is found through the use of straight fin heatsinks. While there are certain environments for which the elliptical fin heatsinks and round pin heatsinks are offered as alternatives, the straight fin design has a wide variety of applications that it is useful for - provided that the given airflow within the device meets the right specifications.

Straight finned heatsink models are found being used in many applications, and they come in a number of different forms. Ranging from skived fin technology to extrusions with high aspect ratios and from stamped fins to castings as well, straight fin heatsinks are a necessary part of the design process for a long list of manufacturers. This is in part due to the fact that production of straight fins can be simpler than other designs, depending on the specific needs in play. In addition, the straight fin prototype is easily compatible with small spaces, making it a very versatile fin shape.

Yet while straight fin heatsinks are found to be useful in a wide variety of applications, there are many environments in which it is useful to consider their alternatives. Round pin heatsinks, for example, are highly responsive to unspecified, omni- or multidirectional environments of ventilation.

Ultimately, it should be recognized that the use of straight fin heatsinks is not always ideal when planning out a thermal strategy. One alternative to straight finned heatsink technology, for example, provides up to a quarter times more efficiency in situations where the ventilation is decreased. It is the round pin heatsink design, and should be considered a necessary replacement in such circumstances. Also, when airflow goes in one specific direction, a manufacturer should turn perhaps to the elliptical fin shape in order to more effectively take care of the component's thermal requirements.
