Thermal - Heat Sinks

7-190-BA Application field and Working Principle

The 7-190-BA Heat Sink comes from Materion, a company that manufacture thermal solutions for a variety of applications. The 7-190-BA is a high performance anodized aluminum extrusion with two large heat sinks that can be used to dissipate large amounts of heat. The 7-190-BA heat sink is designed for applications where a constantly cooling component is necessary, such as an integrated circuit (IC) that is running at high wattage or frequency.The 7-190-BA Heat Sink is made of anodized aluminum, which makes it both lightweight and durable. It has two extruded segments which act like two giant heatsinks. At the top of the extrusion, a heat spreader is attached which distributes the heat evenly between the two segments. The design also utilizes the dissipating properties of thermal material such as graphite, Boron Nitride, clay, and Kapton to promote thermal efficiency and increase the total heat dissipation capacity of the 7-190-BA.The 7-190-BA Heat Sink is designed to be used in applications where the component that needs cooling is running at a higher wattage or frequency, as its ability to dissipate heat more efficiently allows it to stay colder for longer. This can be beneficial in applications such as automotive, aviation, medical, or even aerospace, where controlling and dissipating heat is a critical concern for achieving the desired level of performance.The 7-190-BA works by using the heat sink to absorb the heat that is generated by the component and release it to the outside environment, where it dissipates more quickly. The higher wattage and frequency that the component runs at, the more heat it generates that needs to be released. The 7-190-BA\'s ability to transfer heat faster and from a larger surface area, means that it can efficiently dissipate the large amounts of heat that components running at this level can often generate.When installing the 7-190-BA to dissipate heat, it is important to ensure that there is adequate clearance between the heat sink and the component being cooled. The amount of clearance needed will vary depending on the specific application and the wattage and frequency the component is running at. Additionally, thermal grease should be applied to the contact points between the 7-190-BA and the component being cooled in order to create a better seal and further promote the transfer of heat.In conclusion, the 7-190-BA Heat Sink from Materion is an excellent choice for a variety of applications where cooling a component is necessary. It is made of anodized aluminum, has two extruded segments, and uses thermal material such thermal grease and graphite to boost its heat dissipation capacity. Additionally, if installed correctly, the 7-190-BA is capable of dissipating large amounts of heat generated by components running at high wattage and frequency, making it an ideal choice for applications such as automotive and aerospace.
