Heat dissipation

Underlying technology ► Heat dissipation

This chapter contains basic information on the subject of heat dissipation of devices.

All devices using electric power generate more or less heat which must be suitably dissipated to prevent overheating. Most devices state a permitted temperature range of the ambient air, within which the manufacturer guarantees the device's functionality. Usually, this information is included in the technical data of the device or it is stated on a label affixed to the device. This data presupposes a normal circulation of air to dissipate the heat produced by the device.

If a device is intended for installation in a control cabinet, a control panel or other enclosures, measures must be taken to ensure that the permitted ambient temperature range is not exceeded. It is also important that the air circulation around the device is not overly restricted.
