Problems solved by technology

[0002] With the widespread use of navigation systems, the performance requirements for navigation signal receivers are getting higher and higher. Therefore, the built-in system integration of navigation signal receivers is constantly increasing, the system power consumption is constantly increasing, and the box volume is constantly decreasing, resulting in The temperature rise on the surface of the control circuit board and the internal environment will directly affect the performance of each functional module of the product, resulting in a reduction in the performance, life and reliability of the navigation signal receiver
In addition, the temperature has a great influence on the accuracy of the control circuit board. When the temperature rises, the parameter drift will increase, resulting in a decrease in the performance and life of the integrated control circuit board, which will eventually affect the performance and life of the product. The heat dissipation treatment of the circuit board is an urgent problem to be solved in the thermal design of the product

Abstract

The invention discloses a navigation signal receiver. The navigation signal receiver comprises a shell body, a control circuit board and a heat dissipating component, wherein the shell body comprises a bottom shell with an accommodating cavity and an upper cover which is in matched snap connection with the bottom shell; the control circuit board is vertically arranged in the accommodating cavity of the bottom shell; the heat dissipating component is used for dissipating heat generated by the control circuit board to the outside of the shell body and comprises a first conducting part and a second conducting part which is connected with the first conducting part and is snapped between the bottom shell and the upper cover, the first conducting part is provided with a conducting end, the conducting end extends into the accommodating cavity and is connected with the control circuit board, the second conducting part is provided with a diffusion end, and the diffusion end penetrates through the shell body and extends to the outside of the shell body. According to the navigation signal receiver disclosed by the invention, the heat generated by the control circuit board is conducted out of the accommodating cavity through the conducting end of the heat dissipating component and is dissipated through the diffusion end, so that the internal heat dissipation of the navigation signal receiver is realized.
