A kind of vehicle-mounted lithium ion battery pack heat dissipation device, the purpose of this utility model is that design is a kind of rational in infrastructure, the vehicle-mounted lithium ion battery pack heat dissipation device that result of use is good.The technical solution of the utility model is, a kind of vehicle-mounted lithium ion battery pack heat dissipation device, it comprises blast pipe, blast pipe and air main UNICOM, air main is provided with fabric wind-distributing pipe, described fabric wind-distributing pipe assigns between the neighboring unit cell of battery pack, around battery pack, be provided with exhaust passage, exhaust passage and discharge pipe UNICOM.Described fabric wind-distributing pipe adopts RIPSTOP or polymer fabrics to make.Described exhaust passage can arrange multiple, is centered around the periphery of battery pack.The utility model effectively can improve electric discharge consistency and the capacity usage ratio of the battery of battery pack.
Description
Technical field:
The utility model relates to vehicle-mounted Li-ion batteries piles, particularly a kind of heat abstractor being applicable to vehicle-mounted Li-ion batteries piles.
Background technology:
In recent years, lithium ion battery particularly pure electronic or hybrid vehicle application receives publicity day by day and studies in power, lithium ion battery particularly electrokinetic cell, in utilization process, needs the primary factor of consideration and technical problem how to guarantee the working temperature of battery.Solve useful life and fail safe that heat radiation/heating problems is related to lithium ion battery.
Improving in lithium ion battery working temperature, most producer adopts liquid line cooling and the cooling of outside bleed type, wherein to be liquid to take away (patent publication No.: CN1012222077A, CN1191658C) and the cooling of outside bleed type by metallic conduit to the liquid line type of cooling by the waste heat that battery pack produces be utilize cell module outer portion to dry to be taken out of by hot-air from battery module inside by battery module inside again.These mode main purposes above-mentioned are taken unwanted for battery heat out of battery pack thus are guaranteed that battery works at suitable temperature, but the potential safety hazard inherently making battery pack exist of the metal tubes of liquid cools is large especially, when being especially subject to external impact distortion, flammable conducting liquid is revealed and is also caused very large harm to cell safety, and also remain high on cost, affect the application of battery in motor vehicles for civilian use.In the structure that traditional wind cooled is air-cooled, cold wind is released through battery core gap at outside batteries and takes heat in gap out of battery pack, but due to air-flow in the module one-in-and-one-out easily occur cooling dead angle there is the situation that battery local temperature is too high or too low, like this on battery life impact very large.
Summary of the invention:
The purpose of this utility model is that design is a kind of rational in infrastructure, the vehicle-mounted lithium ion battery pack heat dissipation device that result of use is good.
The technical solution of the utility model is, a kind of vehicle-mounted lithium ion battery pack heat dissipation device, it comprises blast pipe, it is characterized in that: blast pipe and air main UNICOM, air main is provided with fabric wind-distributing pipe, described fabric wind-distributing pipe assigns between the neighboring unit cell of battery pack, around battery pack, be provided with exhaust passage, exhaust passage and discharge pipe UNICOM.Described fabric wind-distributing pipe adopts RIPSTOP or polymer fabrics to make.Described exhaust passage can arrange multiple, is centered around the periphery of battery pack.
Temperature required hot and cold wind can directly send as internal battery pack by the utility model, air externally flows from inside battery and does not affect by battery chamber interior wall, distribute more even, greatly improve utilization ratio that is cold, warm braw, and be distributed in battery module inside with making the air uniform, controllable of adjustment temperature, effectively improve electric discharge consistency and the capacity usage ratio of the battery of battery pack.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Composition graphs 1 describes embodiment in detail, a kind of vehicle-mounted lithium ion battery pack heat dissipation device, it comprises blast pipe 1, blast pipe and air main 6 UNICOM, air main is provided with fabric wind-distributing pipe 2, described fabric wind-distributing pipe assigns between the neighboring unit cell of battery pack 3, is provided with exhaust passage 4 around battery pack, exhaust passage and discharge pipe UNICOM 5; Fabric wind-distributing pipe described in the present embodiment adopts RIPSTOP to make, and polymer fabrics also can be adopted to make, can improve the ventilative property of fabric wind-distributing pipe like this, and fire-retardant; Described exhaust passage also can arrange multiple, is centered around the periphery of battery pack, is convenient to wind like this and discharges from any angle.When the utility model uses, by the air outlet pipeline of air conditioning for automobiles and blast pipe UNICOM of the present utility model, temperature required hot and cold wind so just can also can be ensured directly to send as internal battery pack, improve the temperature control capability of battery pack further.
