Fin stock refers to the aluminum foil attached to the surface of the heat dissipating device, which is expanded or welded. It is usually used in devices for temperature exchange in refrigerator evaporators or other electrical appliances.
Generally, the surface of the heat exchange device that needs to perform heat transfer increases the heat exchange surface area of the heat exchange device by adding a metal sheet with strong thermal conductivity, and the metal sheet having this function is called a fin. There are many types of fins. Such as copper fins, fin stock.

This heat sink is one of the most used heat sinks. It is made of pure aluminum. Aluminum is the most abundant metal on the earth. Its low cost and low heat capacity are its main features. Although the heat absorption is slow, the heat is fast. The heat dissipation effect is proportional to its structure and workmanship. The more heat sinks, the better the bottom polishing, the better the heat dissipation effect. The heat dissipation principle is very simple: use the heat sink on the heat sink to increase the contact area with the air, and reuse The fan accelerates the air flow to remove the heat from the heat sink. The heat sink made of pure aluminum is inexpensive, and the low-end CPU is cost-effective.
