Plate Fin Heat Sink

Plate fin heat sink


What is plate fin heat sink?

Plate fin heat sinks heat transfer by convection and use straight fins that extend the entire length to maximize the surface area of the heat sinks. The large fins give off heat, so more energy can be removed at the same temperature difference. A variant of the straight fin heat sink is the cross cut fin heat sink, in which the straight fin heat sink is cut at regular intervals.


Natural convection plate fin heat sinks

Passive cooling using plate fin heat sink is a fail safe and quiet method, no power consumption, and is easy to manufacture. Natural convection plate fin heat sinks only through conduction, convection or radiation to absorb heat, the temperature can be maintained in the limit range. Plate fin heat sinks absorb heat by natural convection. Heat dissipation is essentially area expansion. The larger the area, the more energy can be removed at the same temperature difference.

The advantages of using a plate fin heat sink

In Lori, passive plate fin heat sinks are usually used on the outside of the mechanical housing and housing. Compared with other cooling methods, the main reasons for using passive plate fin heat sinks are:

 

1. Fail safe

2. Low maintenance

3. No power

4. No noise

5. Simple production methods

 

An important limitation is that the fins should be placed vertically. Otherwise, there will be no optimal airflow. About the plate fin heat sink design, we can calculate and analyze the heat sink through simulation test. In order to improve the performance of the heat sink, we can expand the area by increasing the number of heat sink fin, which will increase the possibility of heat transfer from the heat sink to the surrounding air. This optimizes the air flow between the Plate fins.
