The invention discloses an airborne power battery dynamic pressure variable temperature experiment cabin, which comprises an internal experiment cabin, an external temperature control cabin, a pressure control system and a temperature control system. The internal experiment cabin is used for providing a space for airborne lithium battery combustion, and a gas-liquid fire extinguishing port arranged above the internal experiment cabin. The external temperature control cabin sleeves the experiment cabin. The pressure control system is arranged on the internal experiment cabin so as to control the internal pressure of the internal experiment cabin. The temperature control system is arranged on the external temperature control cabin. According to the airborne power battery dynamic pressure variable temperature experiment cabin, through the arrangement of the external temperature control cabin, the effect of changing the environment where the internal experiment cabin is located can be achieved, and experiment research of a lithium battery under different temperatures, pressures and atmospheres can be better provided.
Description
technical field [0001] The invention relates to an experimental cabin, more specifically to an airborne power battery dynamic pressure variable temperature experimental cabin. Background technique [0002] At present, the traditional airborne halon (Halo) fire extinguishing agent is still widely used at home and abroad, which has the disadvantages of easy reflammation and ozone layer destruction. The International Civil Aviation Organization (ICAO) is actively promoting countries to phase out halon fire extinguishing agents and use their alternative fire extinguishing agents. The main existing halon substitute fire extinguishing agents are 2-BTP, heptafluoropropane (HFC), Novec1230, fine water mist and other fire extinguishing agents. [0003] In China, there is no experimental equipment specially designed and developed for the above several new fire extinguishing agents to extinguish the lithium battery fire. Most of the experimental equipment for lithium battery fire ext...
