Thermal management is becoming a more important element in designing electronic products. The life expectancy and performance are inversely related to the temperature of equipment components. A temperature reduction corresponds exponentially with an increase in the longevity and reliability of a device.
Heatsinks enhance hot surface heat dissipation. The heat generating surface is usually the casing. Heat is dissipated to a cooler ambient that is usually the surrounding air.
A heatsink increases the surface area that comes into direct contact with a coolant. The increased surface area lowers the heat dissipation barrier. The operating temperature of the device is also lowered. The primary function of a heat sink is the maintenance of a device’s temperature below the maximum the device manufacturer specifies is allowable.
Pressure drop and thermal resistance values are typically used to express a heatsink’s efficiency. The air resistance moving through a heatsink is the pressure drop value. It is expressed in mmH2O units. Ideally, pressure drop should be as low as possible. The rate of rise in temperature per watt is the thermal resistance value. Thermal performance increases as the thermal resistance value decreases.
These are rough standards to use in choosing a heatsink. Other factors to consider are heat radiated from other parts to the heatsink and the surface area of the source of heat that touches the heatsink. In the majority of instances, electronic applications that prove to be the most cost-effective are aluminum extruded heatsinks.
Heatsink manufacturers design custom heatsink and extrusion profiles that fit the particular needs of their customers. Optimal thermal management solutions are tailored and provided for each application. Cooling Source is one of the heatsink manufacturers that make custom heatsinks.
