All SSRs generate heat when they operate. Installing a heatsink is an efficient way to manage this heat so it doesn't damage the relay or interfere with its performance.

Relay heatsinks have a number of vertical fins. These fins provide a large surface area to cool the hot air created by the relay's operation. The heatsink needs to be positioned in a ventilated area so the cooled air can be expelled into the environment.
