摘要： A system for cooling electronic components in the downhole assembly of a drill string through which a drilling fluid flows. The cooling system includes a thermoelectric cooler that conducts heat from the electronic component to a first heat transfer surface of a thermally conductive chassis. The heat received by the first heat transfer surface is transferred within the chassis to a second heat transfer surface that then transfers the heat to a housing. The housing transfers the heat to the drilling fluid flowing over the housing. To ensure good conductive heat transfer between the chassis and the housing, the chassis portions are urged outwardly toward the housing surface. A conformable thermal interface material preferably forms the chassis second heat transfer surface. The system may also includes a thermoelectric cooler mounted in a drill pipe portion of the downhole assembly that transfer heat from the an electronic component mounted in the drill pipe to the drill pipe, which then transfers the heat to the drilling fluid.
