Adjustment and detailed design.
Refinement ground, in order to which the cold pipe 11 of liquid can preferably take away the heat of cell 221, the cold pipe 11 of liquid is located at outer framework
Between 21 bottom and the upper surface of pallet 13, the cold pipe 11 of liquid is set adjacent to cell 221.
Refinement ground, installation of the cell 221 in outer framework 21 for convenience fix, outer framework 21 include it is multiple side by side
Unit framework 211, be fixed with a cell 221 per between the adjacent framework of Unit two 211.
As shown in Figure 5 and Figure 6, unit framework 211 is arranged side by side, and forms the outer framework 21 of battery pack;Two neighboring unit
Between framework 211, it can be mutually permanently connected using structures such as buckles.On the one hand, the design of this unit framework, can be with
Simplify assembling process;On the other hand, the scalability of battery pack can be improved.Needing to increase or reduce battery pack volume or appearance
In the case of amount, adjustment unit framework 211 is only needed and therebetween cell 221.
For the ease of outer framework 21 in the installation on pallet 13, the lower end opposite sides of each unit framework 211 is provided with
Installation gap 2113, multiple installation gaps are formed between bearing platform 2111, the bearing platform 2111 of the same both sides of unit framework 211
2113 form installation cavity.Put it should be noted that unit framework 211 in Fig. 6 is refered in particular in the lower end of each unit framework 211 in this
Lower end under configuration state, or refer to the one end of unit framework 211 adjacent to the surface of pallet 13.The design of bearing platform 2111, on the one hand
Presence for installation cavity provides suitable supporting and space;On the other hand, also by the setting of bearing platform 2111 so that battery
Group is easier to be installed and fixed with pallet 13.
For the ease of outer framework 21 in the support on pallet 13, the downside of bearing platform 2111 is formed with for being supported in pallet
Support feet 2112 on 13.
Preferably it is fixed in unit framework 211 in order that obtaining cell 221, the inner side of each unit framework 211 is set
Have and formed between the divider 2114 for limiting the installation site of cell 221, adjacent two divider 2114 for supplying one
The cavity that cell 221 is inserted.
Being provided between adjacent cells framework 211 is used to mutually install fixed fixed structure, such as buckle structure is multiple
Unit framework 211 passes sequentially through fixed structure and fixes to form whole outer framework 21, is limited between two neighboring unit framework 211
Accommodate the space of cell 221.Fixed structure can be realized using kinds of schemes, such as screw nut, specifically, this reality
Apply in example, projection 2115 and dop 2116 are provided with the side wall of unit framework 211, dop 2116, which is provided with, is available for projection 2115 to put
Enter the hole clipping 2117 of clamping, each unit framework 211 successively blocks its dop 2116 and the projection 2115 of adjacent unit framework 211
Firmly coordinate, you can realization interfixes.
As shown in Figures 1 to 4, in order to improve the heat conduction velocity and efficiency between the cold pipe 11 of liquid and battery pack 22, liquid is cold
Heat-conducting layer 12 is provided between pipe 11 and battery pack 22.
Refinement ground, heat-conducting layer 12 is to be applied to the heat-conducting glue of the cold periphery of pipe 11 of liquid or the heat conductive pad outside the cold pipe 11 of liquid.Enter
Step refining, heat-conducting glue or heat conductive pad can be made up of epoxy resin or silicon rubber.Further, since the setting of heat-conducting layer 12,

Area, is conducive to the cold pipe 11 of liquid to radiate battery pack 22.
For the ease of the heat of battery pack 22 is distributed, the cold pipe 11 of liquid can be according to battery pack 22 in the row of outer framework 21
Cloth situation is arranged, specifically, and the cold bending of pipe 11 extension of liquid forms M shapes, U-shape or S-shaped shape.So, in M shapes, U-shaped
Shape or the cold pipe 11 of liquid of S-shaped shape bending extension will preferably match battery group 22, be conducive to carrying out battery pack 22 effective heat
Management, makes the keeping temperature uniformity of battery pack 22.Certainly, in other embodiment, the bending of the cold pipe 11 of liquid extension shape and not only
It is limited to M shapes, U-shape or S-shaped shape, its shape can be set according to the deployment scenarios of actual battery group 22.
As shown in Figures 1 to 4, for the ease of putting the cold pipe 11 of liquid, pallet 13 is provided with supporting plate 14, and the cold pipe 11 of liquid is installed
In supporting plate 14.So, supporting plate 14 will form powerful support to the cold pipe of liquid 11.
In order to further form strong support to the cold pipe of liquid 11, as shown in Figures 1 to 4, supporting plate 14 is provided with use
In the groove (not shown) for installing the cold pipe 11 of liquid.So, the cold pipe 11 of liquid will be fixedly supported in groove, and it can prevent liquid cold
Pipe 11 causes situation about fractureing to occur due to excessive rock in use, improves overall security.In addition, supporting plate 14
(such as PPO) is prepared using engineering plastics, the heat that can effectively obstruct between pallet 13 and the cold pipe 11 of liquid is inversely transmitted, improve whole
The heat-conducting effect of battery bag 10.
It should be noted that PPO, Chinese is polyphenylene oxide, English name:Polyphenylene Oxide, PPO are five
One of big general engineering plastic, it has the advantages that rigidity is big, heat resistance is high, fire retardant, intensity is excellent compared with high electrical performance.
Refinement ground, supporting plate 14 is at least partially housed in installation cavity.Herein, Ke Yishi, the part of supporting plate 14 is held
Be contained in installation cavity in or, supporting plate 14 be entirely accommodated in installation cavity in.
As shown in Figures 1 to 4, in order to further prevent the reverse transmission of heat, between the cold pipe 11 of liquid and supporting plate 14
Provided with heat insulation foam 15, so, the upper end of the cold pipe 11 of liquid sets heat-conducting layer 12, and the lower end of the cold pipe 11 of liquid sets heat insulation foam 15, liquid
The upper end of cold pipe 11 will be beneficial to heat transfer, and the lower end of the cold pipe 11 of liquid will be unfavorable for heat transfer.In addition, heat insulation foam 15 is set
Put, be conducive to forming buffering between the cold pipe 11 of liquid and supporting plate 14, and prevent long-term between the cold pipe 11 of liquid and supporting plate 14
Friction.
As shown in figure 1, supporting plate 14 can select to be arranged in a combination by the sub- supporting plate of polylith, it is easy to the peace of supporting plate 14
Dress and design.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Any modifications, equivalent substitutions and improvements made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
