Problems solved by technology
cause a lot of heat
If the heat is not dissipated and suppressed well during the running of the vehicle, there will be a large temperature difference between the individual batteries, resulting in uneven distribution of the heat generation temperature field of the battery pack, which may eventually cause the electrochemical The performance is seriously reduced; at the same time, the temperature difference of each single battery will also cause the difference in the charge and discharge capacity of each power battery, which will eventually reduce the cycle life of the battery pack and greatly reduce the amount of repeated charging. In addition, if the temperature is too high, it is easy to burn out the battery or Vehicle electrical equipment

The invention discloses a heat dissipation method of a special battery for a new energy automobile. When a driving motor works, a heat conducting rod rotates, a heat conduction disc and the centrifugal blades rotate, and the centrifugal blades can generate airflow to dissipate the heat of a battery main body; air enters a placement groove from an air inlet hole of a fixed pipe, is filtered by a filter element and then enters a shell for heat transfer, and then air is discharged from an air outlet. According to the present invention, with the arrangement of the driving motor, the heat conduction rod, the heat conducting disc, the centrifugal blades, the filter element, a heat conducting needle, circular cooling fins, annular cooling fins, bristles and a first mounting strip, the high temperature can be quickly dissipated into the outside air, so that the battery is high in heat dissipation efficiency and good in heat dissipation effect, dust on the circular heat dissipation fins and the annular heat dissipation fins can be automatically brushed away, and the situation that the heat transfer effect of the circular heat dissipation fins and the annular heat dissipation fins is affected due to the fact that the dust is accumulated too thick, is avoided.
Description
[0001] This application is a divisional application of a patent with an application date of May 4, 2018, an application number of 201810421859.8, and an invention title of "a special battery cooling device for new energy vehicles". technical field [0002] The invention relates to the technical field of heat dissipation devices, in particular to a heat dissipation method for a special battery of a new energy vehicle. Background technique [0003] New energy vehicle batteries can be divided into two categories, namely batteries and fuel cells. Batteries are suitable for pure new energy vehicles and can be classified as lead-acid batteries, nickel-based batteries (nickel-hydrogen and nickel-metal hydride batteries), sodium beta batteries (sodium-sulfur batteries and sodium-nickel chloride batteries), two Secondary lithium batteries, air batteries and other types. Fuel cells are dedicated to fuel cell new energy vehicles and can be divided into alkaline fuel cells (AFC), phosp...
