I found these strange heat sinks on smart tvs and was wondering what type of heat sink they are.

They have 4 pins that solder into the board. What is the name of that type of mounting.

I want to find a better replacement but i don't know what type of heat sink this is?

Or what is the name of that type of heat sink mounting system?
