The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
As Figure 1-4, the embodiment of the present application provides a kind of battery bag, including casing 10 and battery control unit 20.
Casing 10 can include the upper box and lower box for sealing against each other connection, battery core is positioned in casing 10, casing 10 is provided with scattered
Hot window 111, the inside of casing 10 is in communication with the outside by radiator window 111.Battery control unit 20 is installed on casing 10, specifically
Ground, battery control unit 20 includes housing 21 and circuit board 23, and housing 21 is provided with accommodating chamber, and circuit board 23 is positioned over accommodating chamber,
Battery control unit 20 is installed on casing 10 by housing 21, and at least part of housing 21 is relative with radiator window 111, and passes through radiating
Window 111 is exposed to the external world, in other words, and the part relative with circuit board 23 of housing 21 can all be exposed to the external world, or only
The partial denudation of housing 21 is in the external world.Alternatively, the closing of housing 21 radiator window 111.
Said structure, casing 10 sets radiator window 111, at least part of housing 21 of battery control unit 20 is exposed to outside
Boundary, so that the heat that the circuit board 23 in housing 21 is distributed is directly delivered to the external world by housing 21, due to the heat transfer road
Footpath needs not move through casing 10, and heat is directly transferred to the external world by housing 21, in the presence of external air flow, can realize quick
The purpose of radiating.Therefore, above-mentioned battery bag can shorten the path of heat transfer, increase the radiating efficiency of battery control unit 20,
Reduce the risk that component is closed in the side effect that big battery core electric current is produced, reduction battery control unit 20, Jin Erbao as far as possible
The normal of card battery management system is used.
Generally, for the convenience of installation, housing 21 includes the drain pan 211 being connected with each other and upper lid 212, such as Fig. 2-3 institutes
Show, drain pan 211 is connected with upper lid 212, its connected mode can be welding, clamping or mode connects for screw, drain pan 211 and upper lid
212 surround above-mentioned accommodating chamber, and in order to which circuit board 23 is positioned over into accommodating chamber, and at least part of drain pan 211 is exposed to the external world；On
Lid 212 is stretched into casing 10 by radiator window 111.
Housing 21 can be installed on the inner side of casing 10, i.e. battery control unit 20 is entirely located in casing 10.In order to protect
The reliability that card battery control unit 20 is connected with casing 10, usually, drain pan 211 is overlapped in casing 10, so that drain pan 211 is remote
One side from upper lid 212 is all exposed to the external world, this structure, can also during other component malfunctions in casing 10
Housing 21 is directly dismantled, in order to repair.
Further, drain pan 211 can close radiator window 111, with increase on the intensity of casing 10, drain pan 211 with casing
10 overlap is circumferentially disposed along radiator window 111, and ensures the reliability that casing 10 is connected with housing 21.Now, dissipate
The edge of hot window 111 can to casing 10 interior lateral bend so that preferably improve casing 10 intensity, and can avoid peace
Scratch is caused to housing 21 during dress housing 21.
Housing 21 can be connected by drain pan 211 with casing 10, and upper lid 212 is stretched into the inside of casing 10 by radiator window 111.
When drain pan 211 is overlapped in casing 10, drain pan 211 is attached with casing 10 by the two part mutually overlapped, and it is connected
Mode for mode connects for screw, welding or can be riveted, preferred mode connects for screw, in order to which battery control unit 20 breaks down when side
Just dismantle and repair.Certainly, housing 21 can also be connected by upper lid 212 with casing 10.
Circuit board 23 can be connected with upper lid 212 or drain pan 211, when drain pan 211 is exposed to the external world, in order to further
Accelerate the efficiency of heat transfer, circuit board 23 is connected to drain pan 211, generally, the plane of flattening of circuit board 23 and the plane of flattening of drain pan 211
It is parallel.Due to being typically welded with various components on circuit board 23, therefore, the two sides of circuit board 23 (including component) is often recessed
Convex injustice, for the stability of the installation that ensures circuit board 23, can be provided with depressed part, the opening of depressed part on drain pan 211
Towards upper lid 212, depressed part includes bottom land and cell wall, and cell wall only can also be sealed partly along the circumferentially closed of radiator window 111
Close.Circuit board 23 is overlapped at the opening of depressed part so that on circuit board 23 close to depressed part bottom land side component
Depressed part can be placed in.
Wherein, the connection of circuit board 23 and housing 21 can be connected by screw, can also by being bonded gemel connection, or
Using the combination of screw and bonded adhesives two ways.Usually, circuit board 23 is connected by way of encapsulating with housing 21.The bottom of at
When shell 211 is exposed to the external world, especially drain pan 211 provided with depressed part, first drain pan 211 is laid flat, then to depressed part encapsulating (recessed
When the cell wall in the portion of falling into is endless totally-enclosed, the part do not closed first is used into encapsulating again after frock closure；When being not provided with depressed part,
Frock can be used to surround a depressed part), then circuit board 23 is positioned on the casting glue of perfusion again, lid is installed
212, finally make embedding adhesive curing, usual casting glue is heat-sensitive glue, therefore the battery control unit 20 installed be put into baking box to make
Embedding adhesive curing, when using other casting glues, can be solidified using corresponding curing mode, so that circuit board 23 is solid
Due to drain pan 211.Wire harness is finally connected to battery control unit 20.
In order to further speed up the radiating efficiency of circuit board 23, the casting glue used in above-mentioned encapsulating is heat-conducting glue 22, circuit
Plate 23 is fixed on drain pan 211 by heat-conducting glue 22, and now casting glue plays heat conduction and fixed effect simultaneously.It is to be appreciated that
When circuit board 23 is connected with housing 21 using other manner, for the radiating efficiency of accelerating circuit plate 23, circuit board 23 and bottom
Other conductive structures, such as heat conductive pad can also be filled between shell 211.
Wherein, upper lid 212 includes receiving portion, and receiving portion is recessed to the side away from drain pan 211, and the region of depression is used for shape
Into above-mentioned accommodating chamber.Receiving portion is located in casing 10.In order to ensure reliability that upper lid 212 is connected with drain pan 211, upper lid 212
Provided with flange, flange is connected to the edge of receiving portion, and flange is connected with drain pan 211.
Housing 21 is exposed to the one side that the part in the external world, especially housing 21 are exposed to the external world, can be all or part of
Planar structure is processed as, can also be in dentalation or other polymorphic structures, dentalation can be broached-tooth design, rake tooth
Or other tooth-shape structures, to increase area of dissipation, accelerate radiating efficiency.As shown in Fig. 1,3,4, drain pan 211 is exposed to the external world
One side be set to tooth-shape structure.
Casing 10 is offered after radiator window 111, and in order to ensure the sealing at radiator window 111, battery bag also includes sealing
Pad 30, sealing gasket 30 can be loop configuration, be arranged at the periphery of radiator window 111, housing 21 passes through the sealed heat-dissipating of sealing gasket 30
Window 111, can be stacked, as shown in Figure 2 with drain pan 211, sealing gasket 30 and casing 10.When upper lid 212 is provided with flange, also may be used
It is stacked with drain pan 211, flange, sealing gasket 30 and casing 10, however, to ensure that the sealing of battery control unit 20, is turned over
While being usually located at the inner side of sealing gasket 30.
Further, since being set up in battery control unit 20 there are multiple components, make the weight of whole battery control unit 20
