Upper lid, connector, panel, fluid sealant, screw 1, heat-conducting silicone grease, lower cover composition.
Upper lid front as shown in Figure 9, is designed with dispersion shape heat sink strip, can install logo additional in Shang Gai.The back side of upper lid
As shown in Figure 10 to Figure 13, sealing strip is designed with boss structure, and glue groove is designed at connector, and inner side is designed with and panel Copper Foil
The plane of contact.
Connector carries out shunting process as shown in Figure 14 to Figure 16, and power line and holding wire are separately done into two lines beam.Often
The circuit that individual connector is extracted does a single wire harness, is wrapped up with tinfoil, and outer layer is wrapped up with corrugated tube.
Panel is as shown in figure 17, surrounding Copper Foil fringing, by supply module, micro controller module, signal acquisition module, control
Output module processed, onboard environmental measurement module, communication module composition.Wherein supply module design magnet ring filter, controls defeated
Go out module design magnetic bead filter.
As shown in Figure 18 and Figure 19, sealing strip designs groove structure to lower cover, and inner side is designed with what is contacted with panel Copper Foil
Plane, in the easy heat producing regions of panel heat conduction post design is increased.Wherein, sealing strip is the inner side shape when upper lid and lower cover are combined
Into sealing position.
Grey parts are glue groove in Figure 18, and dispensing only in groove during dispensing, corner has dumping hole to design, upper and lower cover buckle during installation
Pressure is closed, unnecessary glue just thus discharge by hole；Meshing is panel Copper Foil contact surface in figure, and Copper Foil is close to housing after installation
Form second layer screen layer.
The advance contact pin of connector female end is welded on panel during installation, thermal grease is smeared on the heating column of lower cover, is used a little
Glue machine has put glue in glue groove, and panel is put into into lower cover, is fastened on lower lid with four screws 1, with point gum machine in upper lid glue
Glue is put in groove, upper cover buckle is on lower lid, and alignment uniform pressure is fastened after top and bottom combination is concordant with the screw 2 of coated glue, complete
Into.
Fuel cell controller housing in embodiment 1, can give full expression to out advantages of the present invention：
1st, using the controller of adhesive tape sealing, due to the elasticity of adhesive tape, often adhesive tape compression becomes where screw fastening
Shape good sealing effect, but away from threaded end because elastic reaction housing arch changes, upper and lower covers produce gap, electromagnetic exposure.This
Colloid prolongs gap flowing after invention adopts the monocomponent room-temperature cured elastic conduction glue of slow curing, screw to fix, slow after blind
Solidification, upper and lower covers obtain consistent seal laminating, and good plays the function of dustproof and waterproof, and greatly enhances effectiveness.
2nd, casing shielding design is only done in general electric control, and colloid is aging after life-time service, especially vehicle-mounted, and life-time service goes out
Existing various sealing problems, sealing and shield effectiveness decline.The design uses housing conductive shielding design, shell and panel Copper Foil
Shielding design is connect, double layer screen design more effectively lifts shield effectiveness, even and if due to aging using concavo-convex glue groove colloid
Also can be locked in glue groove, it is ensured that sealing effectiveness.
3rd, traditional increase radiating surface mode is compared, heat not only timely can be shed but also reduce housing by the design
Processing cost, reduce waste of material, mitigate controller overall weight.
4th, using wire harness diversion design, interference problem is avoided well, using making, pile operation is more stable, and efficiency is more
It is high.
Before installation, controller installation fitting：Screw 2, upper lid, connector, panel, fluid sealant, screw 1, heat-conducting silicone grease,
Lower cover.
During installation, the advance contact pin of connector female end is welded on panel, thermal grease is smeared on the heating column of lower cover, is used a little
Glue machine has put glue in glue groove, and panel is put into into lower cover, is fastened on lower lid with four screws 1, with point gum machine in upper lid glue
Glue is put in groove, upper cover buckle is on lower lid, and alignment uniform pressure is fastened after top and bottom combination is concordant with the screw 2 of coated glue, complete
Into.
Environment and electromagnetic compatibility test are done by standard, be can be seen that compared with a generation by test, its water proof and dust proof performance
Have and be obviously improved.
Generation quality 890g, quality 660g after improvement mitigates 230g, and height reduction 10mm, difficulty of processing declines to a great extent.
Heat dispersion is obviously improved, and the maximum temperature of plank reduces about 10 DEG C compared with a generation.
Capability of electromagnetic shielding is also substantially improved compared with a generation.
