NARADA has been granted an invention patent authorization: "A continuous cooling system for battery swapping cabinets"

Article Source：Qichacha | Author：Securities Star | Issuing Time：2024.05.28
Securities Star News: According to data from Qichacha, NARADA (300068) has obtained a new invention patent authorization, titled "A Continuous Cooling System for Battery Exchange Cabinets", with patent application number CN201910904085.9 and authorization date of March 22, 2024.

Patent Abstract: The present invention belongs to the field of charging safety technology for battery swapping cabinets, specifically a continuous cooling system for battery swapping cabinets, including a temperature monitor, controller, reagent bottle, and external pipeline. The external pipeline is equipped with a nozzle corresponding to each battery compartment, and the nozzle extends into the battery compartment; The opening of the drug bottle is equipped with an electric control valve, and an inner tube is set inside the drug bottle. The inner tube is a hard tube, and its axis coincides with the axis of the drug bottle; A guide tube is set at the end of the inner tube, and the lower opening of the guide tube deviates from the axis and points towards the side wall of the drug bottle; The device also includes a temperature monitor installed in each battery compartment; The coolant above the nozzle of the guide tube is sprayed out through the inner tube under pressure, while the coolant below the nozzle overflows from the inner tube through evaporation. The device can release coolant in two stages, with the first stage rapidly cooling and the second stage continuously supplying coolant to prevent temperature rise, effectively avoiding thermal runaway of the battery in the battery compartment.
