A method and system that uses the flow of drilling fluid to cool electrical components in a downhole environment. A substantially cylindrical housing comprises a wall which houses at least one electrical component directly coupled to a thermoelectric cooling device. An opposing surface of the thermoelectric cooling device contacts a flow of drilling fluid through a hollow passageway in the wall. The flow of drilling fluid acts as a heat sink to transfer heat from the cooling device to a remote location. In this manner, heat is efficiently and directly transferred from the electrical component to the cooling device to the drilling fluid, while the location of the present system within a wall of the housing enables reliable protection of sensitive electrical components from hostile effects downhole.
