A temperature control system and methods that remove dust or debris from inside an electrical equipment chassis are provided. One or more fans are placed in or near the exterior of the chassis. The fans are operated either in reverse, forward, pulsing, or reverse pulsing modes to create turbulent air flow through the chassis. The change in air flow pattern helps dislodge dust and particles. Once airborne, the fans can exhaust the dust and particles. Further, some embodiments provide vanes or other elements to further direct air flow. The temperature control system can be used in any electrical equipment that is ventilated with fans. The temperature control system provides the advantage of a low cost and efficient method for ensuring that dust does not accumulate on components within an enclosure.

The shell of an electronic handheld device is adapted for easy and repeated&#x2014;even frequent&#x2014;assembly with and disassembly from the electronics, and the shell is washable, preferably in a dishwasher. Preferably, the shell comprises a plurality of parts that can be easily and repeatedly assembled and disassembled by hand without use of tools. For example, the parts of a telephone handset shell are made to be easily snapped together around, and unsnapped from, the handset's electronics, thereby enabling the shells of the handsets of telephones to be washed to have this function performed by unskilled personnel.
