The cavity sidewalls of the utility model lithium ion battery heap heat radiation monomer is close to the lateral wall of lithium ion battery, has guaranteed that the heat on the lithium ion battery can pass to the heat radiation monomer fast.The heat radiation monomer has good performance of heat dissipation, these heats can be derived from battery pile fast, and heat can not be gathered in battery pile, thus the cell safety problem of effectively having avoided high temperature to cause, the safety of assurance battery pile.
Description of drawings
Below in conjunction with the drawings and the specific embodiments, the utility model and useful technique effect thereof are elaborated, wherein:
Fig. 1 is the structural representation of the utility model lithium ion battery heap.
Fig. 2 is the structural representation of the heat abstractor of the utility model lithium ion battery heap.
Fig. 3 is the structural representation of another execution mode of the utility model lithium ion battery heap heat abstractor.
Embodiment
See also Fig. 1, the utility model lithium ion battery heap comprises: several lithium ion batteries 10 and a heat abstractor 20.
Please continue to consult Fig. 2, heat abstractor 20 comprises the suitable heat radiation monomer 22 of shape of several and lithium ion battery 10.These heat radiation monomers 22 are welded to one another and are one, and its quantity is identical with the number of lithium ion battery 10 in the battery pile.Each heat radiation monomer 22 all is the hollow cylinder of uncovered of the no end, by the material with better heat transfer property, makes as copper, aluminium, steel and various metal alloy, graphite, decalescence material (as the olefin material of filled with carbon fibers) etc.The cavity 24 at heat radiation monomer 22 middle parts is cylindrical, and the diameter of cavity 24 is identical with the external diameter of lithium ion battery 10, therefore can allow lithium ion battery 10 to insert in the cavity 24 just, and the lateral wall of assurance lithium ion battery 10 is close to the sidewall of cavity 24.
When using this lithium ion battery heap as power supply, the heat that each lithium ion battery 10 produces can both pass to heat radiation monomer 22 fast by the sidewall of cavity 24.Simultaneously, because heat radiation monomer 22 has the good heat transfer performance, can guarantee derives concurrent dissipating fast with these heats from battery pile, so heat is not easy to gather in battery pile.Thereby guarantee the normal lithium ion battery heap that uses and be positioned at its inner lithium ion battery 10 the too high phenomenon of temperature can not occur, the cell safety problem of effectively avoiding high temperature to cause.Even improper use has caused the lithium ion battery stack temperature to raise, heat abstractor 20 also can be derived battery pile fast with heat, significantly reduces the possibility of security incidents such as lithium ion battery 10 burns, blast.
See also Fig. 3, in other execution modes of the present utility model, for the shape that makes lithium ion battery heap more regular, can also heat abstractor 20 ' heat radiation monomer 22 ' outside be provided with a shell that is easy to conduct heat 26 '.Shell 26 ', make as copper, aluminium, steel and various metal alloy, graphite, decalescence material (as the olefin material of filled with carbon fibers) etc. by the material that has than high heat transfer coefficient.In execution mode shown in Figure 3, shell 26 ' be cuboid.But, in other embodiments, according to the power supply space and the appearance design needs of power consumption equipment, the square bodily form of described shell 26 ' can also be, different shape such as cylindrical.
What deserves to be explained is, heat radiation monomer 22,22 of the present utility model ' and cavity 24,24 ' for accommodating lithium ion battery 10, correspondence designs, therefore according to the difformity of lithium ion battery 10, heat radiation monomer 22,22 ' and cavity 24,24 ' can also be other shapes beyond the cylinder is as cuboid etc.As long as the lateral wall of lithium ion battery 10 can be close to cavity 24,24 ' sidewall, guarantee that heat can pass to heat radiation monomer 22,22 ' and derived battery pile fast and get final product smoothly.
Certainly, in other embodiments, heat abstractor 20,20 ' heat radiation monomer 22,22 ' and shell 26 ' also can be integrated.
In addition because heat abstractor 20,20 ' heat radiation monomer 22,22 ' and shell 26 ' be by metal material system penta, so heat abstractor 20,20 ' also has better mechanical performance, can play and supports and protective effect being contained in wherein lithium ion battery 10.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
