Anodization of heat sink In some cases, a surface treatment on the aluminum heat sink is required by the application. This article will focus on the most common treatment used in thermal management: anodization. Following a list of different solutions, we will talk...

Heat sinks for cooling power electronic devices are usually made of aluminium. This metal is the best material in terms of different parameters, such as thermal conductivity, weight, cost, availability on the market, and machinability. There are different techniques and technologies used to “create” an aluminium heat sink; in this paper we will go through a list of solutions, describing their limits and benefits.

How to choose the best connection for your air or liquid cooling system.   A heat sink has to interact with both the power source and the cooling fluid. It is also required to connect to the industrial carpentry that will host the electronic device. This...

When electronics devices generate a heat flux higher than 150 W/cm2, the heat transfer coefficient of the air is no longer enough to achieve the thermal requirement. At this point the cooling system requires a different fluid, and usually the liquid cooling system...

Convection is a heat transfer process in which a fluid comes in contact with a warmer surface and removes heat from it. When external means such as pumps or fans are utilized to increase the flow rate, it’s called “forced convection.” This process is widely applied...

Natural convection is one of the most effective solutions to cool electronics devices. Heat sinks used in this area are usually extruded profile saw cut and machined according to the assembling of the electronic components. The main inconvenient of this kind of...

Brazing under controlled atmosphere (the Nocolok® method) is a robust and reliable technology for joining metals for several industry sectors. Originating in the heat exchanger field, brazing was adopted by heat sink manufacturers in the early 2000s. First, it’s...
