Problems solved by technology

Electric vehicle batteries will generate a large amount of high-temperature and high-pressure gas when they are thermally out of control. If the heat is not dissipated in time, the temperature of each single battery will be unbalanced, which will aggravate the inconsistency of the internal resistance and capacity of each single battery. The damage caused by the heat flow to the inside of the battery and the phenomenon of string burning of other units of the battery pack have great potential safety hazards and serious losses

Abstract

The invention relates to the technical field of battery pack heat dissipation, and discloses a battery pack heat dissipating device. The battery pack heat dissipating device comprises a box, wherein abattery pack is arranged in the box, a gas discharging pipeline is arranged on the box, the gas discharging pipeline and the interior of the box are communicated, and a filtering device and a coolingdevice are arranged on the air discharging pipeline. The invention aims to provide the battery pack heat dissipating device. High-temperature high-pressure gas which is generated during a thermal runaway of batteries can be discharged to the outer portion through the gas discharging pipeline, the filtering device and the cooling device are arranged on the gas discharging pipeline, the filtering device can adsorb particles in the high-temperature high-pressure gas, and convert the harmful gas in the high-temperature high-pressure gas into harmless gas, and then after cooling is conducted by the cooling device, the safe gas is discharged to the outer portion of the box, so that temperature reduction and the air pressure stability in the box are guaranteed, the phenomena of cattery internaldamage and series burnout of other units of the battery pack are prevented, damage is reduced, and the safety of the battery pack is guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of a battery pack, in particular to a heat dissipation device for a battery pack. Background technique [0002] The battery pack is the power source of the electric vehicle, and the temperature characteristics of the battery pack directly affect the performance and life of the electric vehicle. Electric vehicle batteries will generate a large amount of high-temperature and high-pressure gas when they are thermally out of control. If the heat is not dissipated in time, the temperature of each single battery will be unbalanced, which will aggravate the inconsistency of the internal resistance and capacity of each single battery. The damage caused by the heat flow to the inside of the battery and the phenomenon of string burning of other units of the battery pack have great potential safety hazards and serious losses. Contents of the invention [0003] Based on the above, the object of th...
