Thermal - Heat Sinks: ATS-04H-178-C3-R0 Application Field and Working Principle

Thermal control of electronic components is a critical factor in electronic system design and heat sinks play a major role in controlling the thermal management of a device. The ATS-04H-178-C3-R0, is part of an extensive aerosol thermal management portfolio. In this article, we will explore its application field and working principle.

Application field of the ATS-04H-178-C3-R0

The ATS-04H-178-C3-R0 is a low-profile extruded aluminum heat sink designed for cooling high-power semiconductor components operating up to 155°C. It is suitable for applications in consumer electronics, automotive, medical, industrial, instrumentation, automotive and solar power systems. This aerothermal part is constructed with slotted fins and can be used in any orientation (horizontal, vertical, etc.). This makes it an ideal solution for applications where space is constrained.

Also, the ATS-04H-178-C3-R0 is equipped with five 4mm diameter terminals which allows for the direct attachment of heat dissipation components or the connection of flexible pipes for forced air cooling. Since the material is anodized aluminum, this heat sink also exhibits very good corrosion resistance, allowing it to function in moist and corrosive environments. Furthermore, its mounting holes are designed to accept standard M3 screws.

Working principle of the ATS-04H-178-C3-R0

The working principle of the ATS-04H-178-C3-R0 is relatively simple. Heat generated by electronic components is conducted from the source component to the heat sink by thermal conduction. The heat is then dissipated from the heat sink by the process of convection. This is the process by which heat is transferred to cooler air from the surface of the heat sink.

In order for the process of convection to be effective, a suitable airflow must be present. This airflow can be achieved either naturally or through forced air cooling with the help of fans or blowers. Natural convection is employed when a fan is not used, whereby the warm air near the heat sink rises and is replaced by cooler air from outside the system, which leads to a continuous cycle of heat convection away from the heat sink.

On the other hand, when a fan is used, the warm air is forced away from the heat sink which increases the convection rate and allows for more efficient cooling. This is called forced convection. It is also important to note that the higher the rate of air flow, the higher the rate of cooling.

Conclusion

In conclusion, the ATS-04H-178-C3-R0 is an ideal solution for applications that require enhanced thermal dissipation. It is suitable for a wide variety of applications due to its versatile design and corrosion resistant material. Furthermore, it utilizes a simple working principle of convection which allows it to efficiently dissipate heat through natural or forced air cooling.
