In each side of U-shaped groove, be that every kind of components and parts are at least offered a boss; It is one of following that described components and parts at least comprise: radiator, capacitance component, reinforcement.
In each side of U-shaped groove, be that described radiator is offered 4 boss, for described capacitance component is offered 3 boss, for described reinforcement is offered 2 boss.
Described boss is the boss that projection or shearing bending form.
The utility model also provides a kind of power cell, comprising: the components and parts of U-shaped slot shell and power cell, respectively offer boss corresponding to position two of U-shaped groove relative sides, and described boss is used for fixedly components and parts.
In each side of U-shaped groove, be that every kind of components and parts are at least offered a boss; It is one of following that described components and parts at least comprise: radiator, capacitance component, reinforcement.
Described components and parts comprise: in each side of U-shaped groove, be that described radiator is offered 4 boss, for described capacitance component is offered 3 boss, for described reinforcement is offered 2 boss.
Described boss is the boss that projection or shearing bending form.
Compared with prior art, the utlity model has following advantage: the utility model scheme main casing adopts the design of U-shaped groove, and directly draws materials on housing, shearing bending is for the constant power assembly, simplify the support fixed form, reduced man-hour, improved equipment efficiency; Radiator double-basis face installing device, the utilance of raising radiator, reduced the volume of unit main body, thereby save from cost; Modular assembling, as much as possible reduced the tolerance while installing, and improved the safety-type of product, thereby more met the accurate principle of industrial design.
The accompanying drawing explanation

Fig. 2 is the structure chart of the U-shaped groove of the utility model;
Fig. 3 is the structure chart of the utility model radiator.
Embodiment
For clearly demonstrating the technical scheme in the utility model, below provide preferred embodiment and be described with reference to the accompanying drawings.
The utility model provides a kind of power cell housing of U-shaped groove structure, two of U-shaped groove relative ，Liang Ge sides, side, respectively offers boss corresponding to position; Described boss is used for fixedly components and parts.
Referring to Fig. 2, one group of boss stamped out of shearing bending respectively from the side, two of left and right of U-shaped groove, boss adopts punching press to form, and can be the tabs of shearing bending, can be also the projection of punching press.Comprise respectively: the first boss 11, the second boss 12, the three boss 21, the 4th boss 22, the five boss 31, the 6th boss 32, the seven boss 41, the 8th boss 42; Wherein the first boss 11, the 3rd boss 21, the 5th boss 31, the 7th boss 41 are in a side of U-shaped groove, and the second boss 12, the 4th boss 22, the 6th boss 32, the 8th boss 42 are in the corresponding symmetric position in another side of U-shaped groove.
Wherein, the first boss 11, the 3rd boss 21, the 5th boss 31, the second boss 12, the 4th boss 22 and the 6th boss 32 are shaped as strip, and horizontal stacking is arranged on side; The 7th boss 41, the 8th boss 42 be shaped as square; All, for the fixing radiator 6 as one of described components and parts, see Fig. 3; One end of radiator 6 is arranged between interior the first boss 11 of U-shaped groove, the 5th boss 31, and the other end of radiator 6 is arranged between U-shaped groove the 3rd boss 21, the 5th boss 31.The 3rd boss 21, the 5th boss 31, for locating radiator 6, prevent that radiator 6 from sliding in the horizontal direction of U-shaped groove.The 7th boss 41, the 8th boss 42, equally for locating radiator 6, prevent that radiator 6 from sliding at U-shaped groove fore-and-aft direction.
