Abstract
The utility model discloses a sealed heat abstractor of latent oily servo motor underground control system, the device includes the top connection, and a housing, the lower clutch, the upper portion fin, irritate capsule and lower part fin, and the filling has the conduction oil in the cavity of shell, on, the lower part fin respectively with last, lower clutch fixed connection, on, fixed connection jar capsule between the fin down, latent oily servo motor's circuit board dress is in irritating the capsule and the two embedment is integrative, the heat that components and parts produced on the circuit board passes through the conduction oil with last, the fin transmits away down, the heat dissipation has both been guaranteed, the resistant oily problem of components and parts has been solved again.
Description
Technical field
The utility model relates to the heat dissipation technology of the oily servomotor downhole control system of diving.
Background technology
The oily servomotor downhole controller of diving is positioned at the sealing drum of a sealing, and there is the hardware components of AC servo the inside, and the Primary Component IPM heating of AC servo is comparatively serious, and downhole control system is in the hot environment again.If the downhole control system heat dissipation design is bad, will cause downhole control system can't normally move premature failure owing to temperature rise is too high.Therefore, the heat sink conception of necessary choose reasonable downhole control system, the radiating effect that just downhole control system is obtained.Guarantee the reliability and the life-span of down-hole servo-control system.
Summary of the invention
The purpose of the utility model provides a kind of sealed heat-dissipating device of latent oily servomotor downhole control system, and this device can improve the radiating effect of control system, finally guarantees the reliability and the useful life of system.
The technical scheme of the utility model is: the oily servomotor downhole control system sealed heat-dissipating device of diving, comprise top connection, and shell and lower contact, top connection, shell and lower contact are threaded successively; In the cavity that top connection, shell and lower contact surround jointly; The sealing heat abstractor also comprises top fin, embedding shell, bottom fin, and in this cavity, is filled with conduction oil, wherein the rectangular sheet of upper and lower part fin; The embedding shell is the rectangular channel shape; The upper and lower part fin is fixedly connected with upper and lower joint respectively, and the housing of embedding shell is welded to connect plate up and down, and upper and lower connecting plate is connected through bolt respectively with upper and lower fin; The circuit board of latent oily servomotor is contained in the embedding shell and the two embedding is integral.
In order to realize effective monitoring to down-hole pressure; Be somebody's turn to do the oily servomotor downhole control system sealed heat-dissipating device of diving; Also comprise pressure sensor; On the interior lower end face of lower contact, holddown groove is set, this pressure sensor is installed in the holddown groove, and pressure sensor is fixedly connected with following fin through lead.
The utlity model has following beneficial effect: this oily servomotor downhole control system sealed heat-dissipating device of diving; Wherein the circuit board of latent oily servomotor is contained in the embedding shell; With the heat conduction casting glue the two embedding is integral then, the heat that components and parts produce on the circuit board is passed to shell through conduction oil and upper and lower fin, passes to outer well liquid again; Both guaranteed heat radiation; Solved the oil resistant problem of components and parts again,, and helped improving the useful life of downhole control system for the oily servomotor downhole control system of diving provides safeguard.
