Description
Technical field
The utility model relates to the sealing and anti-leakage structures of a kind of controller housing and water-cooled plate.
Background technique
The heat that IGBT and thin-film capacitor generate at work in controller is more, generallys use liquid cooling mode and carries out to it
Heat dissipation.Coolant liquid in water-cooled plate is flowed into from water inlet, flows through water-cooled plate water channel circulation cooling, then flow out from water outlet, thus
Realize the heat dissipation of IGBT and thin-film capacitor.To prevent coolant liquid from entering inside controller, water-cooled plate channel inlet outlet and shell it
Between sealing it is most important.Currently, the sealing between water-cooled plate channel inlet outlet and controller housing mainly uses O-ring real
Existing, the sealing structure is simple, and after sealing ring long-time use, the sealing ring failure easy to aging that deforms causes coolant liquid to be revealed,
To controller, other workpieces are impacted, and then influence the performance of vehicle, are damaged to driver and rider.
Utility model content
The purpose of this utility model is to provide the sealing and anti-leakage structure of a kind of controller housing and water-cooled plate, the sealing knots
Structure sealed reliable, sealing effect are good.
To achieve the above object, the utility model uses following technical scheme: including water-cooled plate and controller housing, institute
It states the water inlet of water-cooled plate and water outlet is respectively equipped with the sealing element mutually sealed with controller housing, the sealing element includes
O-ring positioned at inner ring and the plain washer positioned at outer ring, the O-ring and plain washer are in same level, and the two
Concentric structure is formed, entirety is linked to be by rubber strip between the O-ring and plain washer.
The controller housing is equipped with the O-ring groove and plain washer groove matched with O-ring and plain washer, institute
The region stated between O-ring groove and plain washer groove is equipped with gap.
The water-cooled plate and controller housing is fixed to realize sealing element and water-cooled plate and controller by bolt presses
The end face seal of shell.
As shown from the above technical solution, the utility model is by using the double-layer sealing structure of O-ring and plain washer to mention
The leakproofness of high water-cooled plate and controller housing；By the way that spilling water is arranged among controller housing and the corresponding groove of sealing element
Mouthful, the coolant liquid of leakage can not only be discharged, and can prevent coolant liquid from entering inside controller housing, reinforce sealing effect.
Detailed description of the invention
Fig. 1 is the decomposition texture schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model sealing element；
Fig. 3 is the structural schematic diagram of sealed groove on the utility model controller housing；
Fig. 4 is the schematic cross-section of the utility model sealing structure.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
The sealing and anti-leakage structure of a kind of controller housing and water-cooled plate as shown in Figure 1, Figure 2, Figure 4 shows, including water-cooled plate 1 and
Controller housing 2, water inlet and the water outlet of water-cooled plate 1 are respectively equipped with the sealing element 3 with the sealing of 2 phase of controller housing, close
Sealing 3 includes the plain washer 32 positioned at the O-ring 31 of inner ring and positioned at outer ring, and O-ring 31 is in identical flat with plain washer 32
In face, and the two forms concentric structure, is linked to be entirety by rubber strip 33 between O-ring 31 and plain washer 32.Specifically,
It is exactly between water-cooled plate 1 and controller housing 2 using two way seal, water inlet or water outlet of the O-ring 31 of inner ring to water-cooled plate 1
Mouth forms sealing, prevents the leakage of 1 channel inlet outlet coolant liquid of water-cooled plate；32 1 direction of plain washer of outer ring prevents the cold of leakage
But liquid enters inside controller housing 2, on the other hand prevents the dust in controller housing 2 from entering the water channel of water-cooled plate 1, two-way
Leakproofness of the structural strengthening of sealing between water-cooled plate 1 and controller housing 2.
Further, as shown in figure 3, controller housing 2 is equipped with the O-ring matched with O-ring 31 and plain washer 32
Groove 21 and plain washer groove 22, the region between O-ring groove 21 and plain washer groove 22 are equipped with gap 23.If cooling
When liquid leaks from the O-ring of inner ring, controller housing 2 can be discharged by gap 23, to prevent coolant liquid from plain washer
22 are leaked to inside controller housing 2.
Further, water-cooled plate 1 and controller housing 2 by bolt presses it is fixed with realize sealing element 3 and water-cooled plate 1 and
The end face seal of controller housing 2.
For the utility model in assembly, the sealing element 3 at the inlet and outlet of 1 water channel of water-cooled plate is respectively placed in control
On device shell 2 processed in corresponding sealed groove, compression is bolted in water-cooled plate 1 and shell 2, to realize sealing element
With the end face seal of water-cooled plate 1 and controller housing 2.
The utility model has the beneficial effects that: 1) sealing element is two way seal, has two layers of inner ring and outer ring, pass through bilayer
Sealing improves the leakproofness of water-cooled plate and controller housing；2) controller housing is equipped with groove corresponding with sealing element, In
Gap is arranged in the intermediate region of inner ring and outer ring, and the coolant liquid of leakage can be discharged by gap, prevent coolant liquid from entering control
Device enclosure interior processed reinforces sealing effect.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines
In range.
