AI Technical Summary
During long continuous operation of the GNSS receiver, it will cause the device temperature to rise, affect the stability of the internal circuit, lead to a decrease in positioning accuracy or equipment failure, and accelerate the aging of electronic components, affecting the overall life of the receiver.
A navigation satellite system reception box is designed, including a circuit board, a shell and a heat dissipation block. The shell and a heat dissipation block are made of thermally conductive materials. The circuit board is arranged in the shell and the heat dissipation block is arranged on the circuit board. The heat dissipation block is transferred to the shell through the heat dissipation block, and the heat dissipation efficiency is improved by using the larger surface area of the shell.
Through an effective heat dissipation mechanism, the temperature during the operation of the receiving box is reduced, the stability and positioning accuracy of the circuit are improved, and the service life of the equipment is extended.
