Vehicle-mounted navigator heat dissipating device

Abstract

The invention discloses a vehicle-mounted navigator heat dissipating device. The vehicle-mounted navigator heat dissipating device comprises a housing and a navigator, wherein two sucking discs are mounted at the bottom of the housing through two guide rods; the two the guide rods are fixedly connected with the housing through threaded connection; a window blind is mounted on the left side of thehousing; a groove chamber is formed in the housing and on the right side of the window blind; a fan housing is mounted in the middle position of the window blind; a fan is mounted inside the fan housing; two first connecting pins are mounted on the left side of the groove chamber and on the window blind; the navigator is fixed to right side of a fixing plate; a heat conducting plate is mounted onthe left side of the fixing plate; heat dissipating fins are arranged on the heat conducting plate up and down at equal intervals; a limiting block is arranged on the right side of the inner part of the groove chamber. The fixing plate with the navigator can be pulled out for use, and improvement on the heat dissipating heat of the overall structure is facilitated; the heat conducting plate and aheat dissipating fin structure which are arranged on the left side of the fixing plate can further improve the heat dissipating performance of the device and guarantee normal use of the device.

Description

technical field [0001] The invention relates to the technical field of vehicle navigators, in particular to a vehicle navigation cooling device. Background technique [0002] Car Navigation (Car Navigation) is a driving assistance device that can help users accurately locate the current location, calculate the itinerary according to the established destination, and guide the user to the destination through map display and voice prompts. The operation of the navigator mainly depends on the Global Positioning System (Global Positioning System, referred to as GPS). Car navigators are mainly composed of chips, antennas, processors, memory, and screens. GPS is composed of three parts: space satellite, ground monitoring and user reception. In space, 24 satellites form a distribution network, which are distributed in six geosynchronous orbits 20,000 kilometers above the ground and with an inclination angle of 55°. There are 4 satellites in each orbit. GPS satellites circle the e...

Problems solved by technology

[0003] Due to the structure of the existing car navigator, the shell and the navigator are integrated, the navigator cannot be adjusted according to the needs, does not have a separate structure, and it is inconvenient to install and fix, and the heat dissipation effect is relatively poor, which has certain limitations.
