Road；This part patented technology is using coolant liquid rather than air is as medium, and cold to battery progress by the way of heat exchange
But it or heats.Such as published United States Patent (USP) 20100279154 is used for the cooling battery and/or capacitor module of battery ', it mentions
Go out a kind of battery heat dissipation technology for using phase-change material as coolant, substantially uses compressor and condenser
Use coolant (such as ethylene glycol) or refrigerant (such as R-11 and R134A) as coolant in cooling system.
Above-mentioned several known patented technologies substantially establish refrigerating module outside battery/capacitor group.Institute
These patented technologies having improve the cooling structure around battery and/or capacitor battery/module, or are absorbed in using not
Coldplate or radiating subassembly with material as battery/capacitor module-external.These patented technologies are clearly by battery/capacitor
Device and cooling system are divided into two independent parts.The structure of this split cell and cooling segment, cooling for battery are imitated
Fruit is still limited.The reason is that general lithium ion battery is mainly by anode (Anode, by taking graphite as an example), cathode
(Cathode, by taking lithium as an example), electrolyte are formed with spacer (Separator), and electrolyte leads in most battery
It is often that liquid is also known as electrolyte.But it aoxidizes in order to prevent and moist reason, electrode, electrolyte and necessary isolation
Object is encapsulated in the packaging of permanent seal.Packaging material can also reduce heat transfer, eliminate the machine of electrolyte direct heat transfer
Meeting.And the cooling means of aforementioned known all patented technologies is all the temperature for reducing outside battery module/battery pack.
