Technical field
This utility model is relevant a kind of lithium battery heat conducting module, so that lithium battery monomer is carried out heat radiation person in espespecially lithium battery monomer is arranged at a heat-conductive body by one.
Background technology
Owing to the market of electric motor car is the most ripe, the demand of lithium battery is made to increase.The lithium battery module of prior art electric motor car is mainly provided with a plurality of lithium battery monomer being connected in parallel to each other or connecting in the inside of a shell, the outside of shell is provided with a positive conductive pole and a negative conductive pole, so as to after connecting conducting terminal respectively, export bigger operating current or voltage, and can possess the electric power needed for enough capacitances travel with supply of vehicles when many group assembled lithium battery modules are in a lithium battery box.
The lithium battery box that electric motor car at present is used is a big casing, i.e. has hundreds of the most thousands of lithium battery monomers to arrange in the inner, make the lithium battery box after being completed can weigh more than 500 kilograms after loading many group lithium battery modules.But, owing to easily allowing heat accelerated accumulation in casing when lithium battery module operates, the heat sent at the lithium battery monomer of casing middle section is difficult to rapid dispersion especially, go wrong once lithium battery monomer, it will involve other lithium battery monomers and cause lithium battery module short circuit or other failure situations.
On the market for the many water acquisition of heat dissipation technology of electric vehicle lithium battery case are cold or air cooling mode operates, but the involving great expense and occupy the biggest space of water cooled heat radiating equipment, ventilation type heat dissipation equipment then has heat radiation dead angle to cause uneven situation of dispelling the heat, and both heat dissipation technologys all can consume the electric power that lithium battery module is laid in, in electric motor car and impracticable when running.
Utility model content
In view of this, in order to provide a kind of structure being different from above-mentioned prior art, and improving disadvantages mentioned above, inventor amasss experience for many years and constantly researches and develops improvement, then has generation of the present utility model.
A purpose of the present utility model is providing a kind of lithium battery heat conducting module, wherein the end face of this heat-conductive body is provided with an opening, it is placed in this heat-conductive body by this opening for a plurality of lithium battery monomers, can effectively absorb lithium battery monomer produced heat when running, to dispel the heat, makes lithium battery monomer can normally play its physical property function and promote its service life.
In order to achieve the above object, the lithium battery heat conducting module set by this utility model includes a heat-conductive body and is located at the opening of this heat-conductive body end face, is placed in this heat-conductive body by this opening for a plurality of lithium battery monomers.
During enforcement, this heat-conductive body is made up of single metal conducting strip.
During enforcement, this heat-conductive body is connected with each other by a plurality of metal conducting strips and is constituted.

Detailed description of the invention
Refer to Fig. 1-2, it is an embodiment of this utility model lithium battery heat conducting module, including a heat-conductive body 1, a plurality of lithium battery monomer 2 and a casing 3, wherein this heat-conductive body 1 is the cuboid framework (as shown in Figure 1) being made up of in one-body molded mode single metal conducting strip, the end face of this heat-conductive body 1 is formed with an opening 11, and these heat-conductive body 1 central authorities are provided with a metal partion (metp) 12, in making this heat-conductive body 1, form two accommodation spaces.Furthermore, made by the material of the metal material such as above-mentioned conducting strip and this casing 3 copper alloy, aluminium alloy or other tool good heat conductive effects.
The front of this casing 3 and left and right side are all provided with multiple vent 31, and the back side of this casing 3 is provided with an exhaust equipment 32 with multiple fan.
During enforcement, such lithium battery monomer 2 is placed in this heat-conductive body 1 (as shown in Figure 2) respectively by the opening 11 of this heat-conductive body 1 end face of its underrun, and the size shape that the size shape of each accommodation space is overall slightly larger than installing lithium battery monomer in the inner in this heat-conductive body 1, make this heat-conductive body 1 directly about and fit such lithium battery monomer 2 around.Then, again the heat-conductive body 1 being equipped with such lithium battery monomer 2 is installed in this casing 3, so as to utilizing this heat-conductive body 1 and dividing plate 12 to absorb heat energy produced by each lithium battery monomer 2 when lithium battery module operates, and then by the vent 31 of casing 3, heat-conductive body 1 is dispelled the heat.
In addition, when temperature in casing 3 reaches a predetermined temperature, the fan power supply of this exhaust equipment 3 can be opened to be discharged outside casing 3 by the hot-air in casing 3, and suck outside air actively to form cross-ventilation in casing 3 in via such vent 31, and then the temperature in control casing 3.
In other embodiments, above-mentioned such heat-conductive body 1 also can be connected with each other by a plurality of conducting strips and constitute, and more can arrange a plurality of metal partion (metp) with improving heat radiation efficiency on demand in this heat-conductive body 1.
Therefore, this utility model can expand total area of dissipation with physics heat-conducting mode, reduce the operational temperature of each lithium battery monomer in lithium battery module, and the exhaust equipment recycled in serial or parallel connection becomes to have the large-scale lithium battery module of up to a hundred lithium battery monomers on casing makes the air in casing flow with vent, contribute to quick soaking to form preferable lithium battery working environment, effectively reduce the operating temperature of the lithium battery monomer in module central region, avoid the usefulness balance having influence between lithium battery monomer because heat differential is different, and then promote the performance uniformity of lithium battery, and (such as cylindrical or square-type lithium battery module) among variously-shaped lithium battery module can be applicable to according to design requirement.
In sum, according to content disclosed above, this utility model really can reach the expection purpose of utility model, a kind of decline that can reduce battery efficiency is provided, the distribution of the homogeneous temperature in lithium battery module case body is made to promote the lithium battery heat conducting module of lithium battery service efficiency and life-span, the value that great industry utilizes.
