Abstract

The invention relates to a cooling system for electronic devices used in downhole operations. In this case, the invention provides a downhole electronics cooling system comprising a first heat exchange element (1) inside a heat exchange vessel (3), and a second heat exchange element (2) associated with an electronics (4), where the first heat exchange element (1) and the second heat exchange element (2) are fluidly communicated by a cooling fluid, where the heat exchange vessel (3) allows circulation of a secondary cooling fluid.

Description

technical field [0001] The present invention relates to cooling systems for electronic devices used in downhole operations. Background technique [0002] Many electronic devices used in downhole operations generate high heat during their operation. Often, the heat generated is so high that it can cause damage to the electronic device itself or components associated therewith. [0003] In particular, laser perforating gun systems require cooling so that their operation does not suffer from failure due to high operating temperatures. Accordingly, the difficulty of cooling these laser perforating gun systems makes their use in drilling and perforating operations difficult and even prevents their use in drilling and perforating operations. [0004] Therefore, when such devices require cooling in order for them to exhibit sufficient efficiency and have a minimized lifespan for performing various operations, the means to exchange heat between the external environment of the tool...
