Vehicle-mounted signal processing box

Abstract

The invention discloses a vehicle-mounted signal processing box which comprises an upper cover, the upper cover is made of plastics, a heating element is arranged in the upper cover, the upper cover is connected with a lower cover made of metal materials, a heat dissipation device is arranged on the lower cover, and the heat dissipation device is made of heat dissipation glue or heat dissipation fins. The lower cover made of the metal material has the advantages that the heat dissipation performance is high, the metal lower cover can take away heat of the heating element by additionally arranging a heat dissipation device, the heat dissipation effect can be achieved, the partition plate made of the dustproof material is arranged between the upper cover and the lower cover, the partition plate is made of the plastic, and the heat dissipation effect is good. The periphery of the partition plate is provided with a wrapping edge protruding upwards and matched with the upper cover, three supporting rods are arranged in the middle of the partition plate, an opening is formed among the three supporting rods, and a heating element in the upper cover is connected with a heat dissipation device on the lower cover through the opening. Therefore, the defects of the metal lower cover can be overcome by means of the partition plate.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle-mounted signal processing box Background technique [0002] The on-board signal processing box is divided into 7 working states, and each state is represented by a different state of B+, ACC, communication (call, data, SMS), GPS, and CAN. This series of functional experiments is inseparable from complex electronic components. The powerful functions brought by the increase of electronic components also bring high heat consumption, which will make the electronic components in the vehicle signal processing box Working in a high heat environment, the hot air cannot be effectively discharged, which will affect the life of electronic components and chip processing speed. [0003] At present, the shape of the vehicle-mounted signal processing box generally involves two schemes: the first scheme is that the vehicle-mounted signal processing box includes a plastic lower cover, and th...

AI Technical Summary

Problems solved by technology

The advantages of this solution: good dust-proof sealing performance, and the upper cover and the lower cover can have a good fit; the disadvantage of this solution: the heat dissipation performance is not good, because it is all wrapped, the heat of the components cannot be dissipated quickly

Disadvantages of this solution: poor dust-proof sealing, the metal lower cover cannot be molded and diversified like plastic parts, the connector cannot be well wrapped, and the lower cover and the upper cover cannot be fully contacted and matched
