navigation signal receiver

Abstract

The invention discloses a navigation signal receiver, which includes a housing, the housing includes a bottom case with a containing cavity and an upper cover that fits and engages with the bottom case; a control circuit board vertically arranged in the containing cavity of the bottom case; and The heat dissipation component used to dissipate the heat generated by the control circuit board to the outside of the casing, the heat dissipation component includes a first conduction part, and a second conduction part connected with the first conduction part and clamped between the bottom case and the upper cover , the first conduction part has a conduction end, and the conduction end extends into the accommodation chamber to connect with the control circuit board; the second conduction part has a diffusion end, and the diffusion end passes through the housing and extends to the outside of the housing. The navigation signal receiver of the present invention conducts the heat generated by the control circuit board from the containing cavity through the conduction end of the heat dissipation component, and dissipates the heat through the diffusion end, thereby realizing internal heat dissipation of the navigation signal receiver.

Description

technical field [0001] The invention relates to a navigation signal processing device, in particular to a navigation signal receiver. Background technique [0002] With the widespread use of navigation systems, the performance requirements for navigation signal receivers are getting higher and higher.

[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
