Abstract
A method of cooling a downhole tool. A first step involves providing a cooling chamber in the downhole tool. The cooling chamber is positioned in proximity to components to be cooled. A second step involves ports through defining walls of the downhole tool. The ports must be adapted to allow liquids from a well bore, in which the downhole tool is positioned, to communicate with the cooling chamber. A third step involves providing means to circulate liquids from the well bore in through the ports into the cooling chamber and out through the ports back into the well bore, such that the liquids in the cooling chamber are continually being replaced. A heat exchange takes place between the liquids in the cooling chamber and the components to be cooled. The liquids are continually being replaced dissipating heat into the well bore.
