Description
Technical Field
The utility model relates to an electric motor car technical field especially relates to a take encapsulating instrument structure of forced air cooling passageway.
Background
The instruments present on the market are mainly divided into two main categories according to the screen material: one is an LED screen meter and the other is a liquid crystal screen meter. Due to the reasons of simple technology, strong temperature resistance, various colors and the like of the LED instrument, the market holding amount is more than that of a liquid crystal instrument. The LED instrument is mainly formed by combining a transparent upper cover, a sticker, a light-transmitting plate, a PCB (printed Circuit Board) plate and a bottom shell lower cover, and an internal outgoing line extends out of the bottom shell lower cover and is connected to a whole vehicle wire harness. At present, the electric vehicle instrument structure is only used as an appearance part, most of design ideas are considered from aspects of fashionable appearance and the like, but a power supply chip of the instrument generates a lot of heat along with the influence of long service time and road complexity, and if the heat is not dissipated in time, the service life of the chip is influenced, even the chip is burnt out. Therefore, a structure for dissipating heat inside the meter in time is urgently needed.
Disclosure of Invention
The utility model discloses the inside accumulated heat volume of instrument to existence among the prior art leads to the defect that the instrument damaged, provides a new encapsulating instrument structure of area forced air cooling passageway.
In order to solve the technical problem, the utility model discloses a following technical scheme realizes:
the utility model provides a take encapsulating instrument structure of forced air cooling passageway, includes upper cover, lower cover, light-passing board, circuit board, still includes the fin, cover down and be provided with the louvre, the fin is fixed in the louvre.
The arrangement of the radiating fins provides channels for radiating of each internal element, and timely radiating can enable the service time of each element to be longer.
Preferably, the glue-pouring instrument structure with the air cooling channel comprises an upper cover and a lower cover, wherein the upper cover is provided with an upper surrounding edge, the lower cover is provided with a lower surrounding edge, the upper surrounding edge and the lower surrounding edge surround to form a heat dissipation space, the heat dissipation holes are located in the heat dissipation space, the heat dissipation space is filled with heat dissipation glue, and the heat dissipation fins are in contact with the heat dissipation glue.
The filling of the heat-dissipating glue allows the heat generated by the components to be transferred more quickly to and ultimately from the heat sink.
Preferably, the glue-pouring instrument structure with the air cooling channel further comprises a sealing ring, and the sealing ring is connected with the light-transmitting plate and the circuit board.
The setting of sealing washer makes the heat dissipation glue can stay in the heat dissipation space when filling, can not influence the normal work of each component.
Preferably, in the glue-pouring instrument structure with the air-cooling channel, the upper surface of the heat dissipation plate is abutted to the circuit board.
The contact area between the radiating fins and the radiating glue is increased by the arrangement of the upper surfaces of the radiating fins and the butting of the circuit board, and the radiating efficiency can be improved.
Preferably, in the glue-pouring instrument structure with the air cooling channel, the heat dissipation fin is further provided with a lower heat dissipation vertical plate.
The arrangement of the lower radiating vertical plate increases the contact area between the radiating fins and the outside air, and the radiating efficiency can be improved.
Preferably, in the glue-pouring instrument structure with the air cooling channel, an air duct is formed between the lower heat dissipation vertical plates, and the air duct is longitudinally arranged.
The air duct is vertically arranged, and when the electric vehicle rides, air flows along the air duct, so that the heat dissipation efficiency is further improved.
