Heat dissipation optimization structure for precision devices in inertial navigation products

Abstract

The invention provides a heat dissipation optimizing structure for a precise device in an inertial navigation product. The precise device is contained in an installation hole of a box body and a gap between the precise device and the box body is filled with a soft silica gel heat-conductive fin. One face of the soft silica gel heat-conductive fin makes tight contact with the surface of the precise device and the other face of the soft silica gel heat-conductive fin makes tight contact with the rear surface of a heat dissipation device fixedly connected with the box body. The soft silica gel heat-conductive fin is arranged in the gap between the precise device and the box body so that the air gap can be eliminated, thermal contact resistance between the precise device and the box body can be reduced, heat generated by the precise device can be rapidly conducted to the surface of the box body, a thermal field inside the product can be balanced rapidly, and influence on performance indexes of the precise device by the environment temperature can be reduced. Meanwhile, heat is dissipated in a conductive mode, a convective mode and a radiant mode, so that the heat dissipation effect is good, the reliability of the product is improved, the service life of the product is prolonged, the structure is easy to obtain, and the usability is high.
