Abstract
Cooling apparatus and methods for use with downhole tools are described. An example apparatus includes a cooling apparatus for use with a downhole tool. The cooling apparatus includes a flow passage having an inlet and an outlet. The outlet is configured for fluid communication with a wellbore and the inlet is spaced from the outlet. The cooling apparatus also includes a pump configured to convey at least one of a drilling fluid or a formation fluid between the inlet and the outlet. Additionally, the cooling apparatus includes a heat exchanger coupled to a surface adjacent the flow passage and a component of the downhole tool to convey heat from the component to the cooling fluid.
