Abstract: A core module assembly of a retail terminal includes a microprocessor which performs computing functions associated with operation of the retail terminal, whereby heat is generated by the microprocessor during performance of the computing functions. The core module assembly further includes a first heat transfer structure positioned in thermal communication with the microprocessor. The first heat transfer structure has a body portion and a key portion extending from the body portion. The core module assembly also includes a second heat transfer structure having a keying slot defined therein. Relative movement between the first heat transfer structure and the second heat transfer structure is limited when the key portion of the first heat transfer structure is positioned within the keying slot of the second heat transfer structure. The core module assembly includes a fastener for maintaining the key portion of the first heat transfer structure within the keying slot of the second heat transfer structure.

Abstract: A core module assembly of a retail terminal includes a microprocessor which performs computing functions associated with operation of the retail terminal, whereby heat is generated by the microprocessor during performance of the computing functions. The core module assembly also includes a housing for containing the microprocessor. The housing has a first fastening surface. The housing also includes a heat transfer structure positioned in thermal communication with the microprocessor. The heat transfer structure has an elongated channel defined therein. The core module assembly further includes a heat dissipating cover having an elongated tongue extending therefrom. The cover further has a second fastening surface. The cover is positionable between a non-biased position and a biased position.
