a hydrogen controller

Abstract

The invention discloses a hydrogen controller, comprising: a hydrogen controller shell, a control circuit board and a heat dissipation base. The structure of the hydrogen controller shell includes: an upper shell and a lower shell are fixed by a locking assembly, The groove and the resting platform of the lower case form a first accommodating chamber, the front end of the upper case and the accommodating notch of the lower case form a second accommodating chamber, and a first lower seal is arranged on the groove wall of the accommodating notch. Ring slot, the upper surface of the lower shell is provided with a second lower sealing ring slot, the first lower sealing ring slot is connected with the second lower sealing ring slot to form a continuous lower sealing ring slot, the lower sealing ring A lower sealing ring is provided in the ring clamping groove, an upper sealing ring clamping groove is provided on the upper surface of the lower housing, and an upper sealing ring is provided in the upper sealing ring clamping groove. When the upper housing and the lower housing are fixed, the upper housing and the lower housing are fixed. The lower casing will squeeze the upper sealing ring and the lower sealing ring to realize the waterproof sealing of the hydrogen controller casing. The invention has the advantages of good waterproof effect, strong heat dissipation performance and convenient assembly.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a hydrogen controller applied to a vehicle-mounted hydrogen automatic detection and control system of a hydrogen energy vehicle. Background technique [0002] As one of the clean energy sources with the most development potential in the world, hydrogen energy is considered by many countries, car companies and scholars as the "ultimate new energy vehicle solution". Hydrogen vehicles refer to vehicles that use hydrogen as fuel, generate electric current through chemical reactions, and rely on electric motors. They are mainly divided into hydrogen internal combustion engine vehicles and hydrogen fuel cell vehicles. [0003] Hydrogen is the gas with the lowest density known in the world. The density of hydrogen is only 1 / 14 of that of air. Therefore, hydrogen leakage is very easy to occur in the on-board hydrogen storage system. Under normal temperature and pressure, hyd...

Problems solved by technology

This solution mainly has the following disadvantages: (1) The structure of the hydrogen controller is simple, it is not easy to disassemble, and the internal parts cannot be replaced or repaired, and the relevant components cannot be reused after a failure; (2) The structure of the hydrogen controller cannot effectively dissipate heat , causing the circuit board in the hydrogen controller shell to be easily overheated and burn out; (3) The controller shell is not drop-proof and vibration-proof, and falling or impact during production, installation or transportation may cause failure of components on the circuit board or damage; (4) When the sealant is applied during assembly, irritating gas will be released, which will cause harm to the working environment, and the sealant will take about 0.5 days to cure, which will affect the product supply cycle; (5) When a failure occurs, it needs to Matching tools are required to remove the hydrogen controller
