Directional temperature control energy storage battery sealed cabin system

Abstract

A directional temperature control energy storage battery sealed cabin is composed of a sealed cabin, a membrane separation nitrogen and oxygen device, a two-way airflow control unit, a heat exchanger,airflow control units, a sensor set and a controller. The sealed cabin is a heat-preservation, waterproof, airtight and pressure-bearing cabin body, the bidirectional airflow control unit is mountedat a corner at one side of the bottom in the sealed cabin, and the airflow control units are respectively arranged at the top and the bottom in the sealed cabin; the heat exchanger is arranged on theshady side of the sealed cabin, the gas in the sealed cabin exchanges heat with the air outside the sealed cabin through the heat exchanger, and the membrane separation nitrogen-oxygen device is arranged at one side, close to the edge, of the top outside the sealed cabin; the controller reads an energy storage battery management system BMS to obtain the temperature of each energy storage battery placed in the sealed cabin, and the controller is embedded into a cabin door of the sealed cabin and is used for receiving the sensor data and the device control. Through the compressed air and the membrane nitrogen-oxygen separation device, the directional temperature control is achieved, the dust prevention and fire prevention are achieved, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to a sealed cabin. Background technique [0002] At present, a large number of outdoor energy storage batteries are installed in containers. However, the centralized packing space is small, requiring high equipment installation density, and heat dissipation has become one of the key points to ensure reliable operation of equipment. At present, air conditioners or fans are mostly used to blow air at one point to form gas convection. Since the arrangement of equipment will hinder the flow of airflow, as the density of equipment placement increases, the possibility of effective temperature control is greatly reduced, and equipment that does not need heat dissipation participates in heat exchange, and competition is limited. resources, increasing heat dissipation power consumption. In particular, the container exhaust heat dissipation directly exchanges heat with the outdoor atmosphere, resulting in dust pollution, increased humidity...
