Problems solved by technology
The disadvantage of ceramic packaging materials is that the cost is high, and the density of ceramic materials is high. When used as the packaging material of the intelligent drill-guiding mechanism, its quality is high, which makes the driving cost of the drill bit high. How to choose a lightweight package with good heat insulation performance Materials, an important issue in the thermal management of electronic devices

The invention relates to an electronic system thermal management packaging device for a high-temperature environment. The electronic system thermal management packaging device comprises a tool inner cylinder, a tool outer cylinder and an aerogel thermal insulation layer. A channel for slurry circulation is formed in the tool inner cylinder, the tool outer cylinder sleeves the tool inner cylinder and is arranged at an interval with the tool inner cylinder, and the aerogel thermal insulation layer is arranged in the interval; and a bracket used for installing a circuit board is arranged on the outer side wall of the tool inner cylinder, the circuit board is installed on the bracket, and a heating component on the circuit board is arranged towards the tool inner cylinder. According to the characteristics and structural characteristics of the environment where the device is located, the aerogel heat insulation layer is adopted for heat insulation design for the boundary of the high-temperature environment, and adverse effects of the high-temperature environment on the interior of the device are prevented; and the tool inner cylinder can be used for slurry to flow through at a high speed, the slurry flowing at the high speed is used as a heat dissipation cold source of the device, the heating component on the circuit board is arranged towards to the tool inner cylinder, and heat generated by the heating component can be taken away through the slurry flowing in the tool inner cylinder.
Description
technical field [0001] The invention relates to the related technical fields of drilling and well logging, in particular to the technical fields of rotary steerable drilling and well logging in high-temperature and high-pressure environments of oil and gas fields, and in particular to a thermal management packaging device for electronic systems used in high-temperature environments. Background technique [0002] Rotary steering and logging technology is a new technology, representing the highest level of drilling technology development. Domestic research on rotary steerable and logging technology started relatively late. The development of rotary steerable drilling and logging technology with independent intellectual property rights can significantly improve the competitiveness of our oilfield service market and generate huge economic benefits. The smooth operation of the electronic components in the rotary steering and logging system determines whether the entire drilling a...
