Description

Technical Field

[0001] The present invention belongs to the field of battery technology, and in particular relates to a compartment-based thermal management system for a battery system and communication equipment. Background Art

[0002] Existing battery and communication equipment integrated systems mainly use the following solutions for thermal management: (1) Integrated temperature control design: The battery module and communication equipment share the same thermal management system (such as a water-cooled plate or air duct), relying on a single cooling source for overall cooling. (2) Passive air cooling technology: Heat dissipation is achieved through natural convection or forced air supply. It is applied to low-power density communication base stations, but has problems such as low heat dissipation efficiency (the specific heat capacity of air is only 1kJ / kg·K) and insufficient temperature control accuracy. (3) Regional heat exchange: Some attempts have been made to set up partitions between the battery and equipment compartments, but physical isolation of the thermal management system has not been achieved.

[0003] However, the above thermal management method has the following limitations: (1) Risk of thermal coupling interference: When the battery and the equipment share a cooling system, the heat of high-temperature electronic components (such as communication chips) may be reversely transferred to the battery compartment, accelerating battery aging (the life decay rate of lithium iron phosphate batteries increases by 300% above 60°C). (2) Energy efficiency waste: Traditional integrated temperature control needs to always maintain a low temperature for the entire system, while communication equipment only needs intermittent efficient heat dissipation, resulting in redundant energy consumption. (3) Maintenance safety hazards: Fire extinguishers cannot accurately locate the source of fire, and battery thermal runaway may ignite the cables in the equipment compartment. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a compartmentalized thermal management system for battery systems and communication equipment, aiming to solve the problems of thermal coupling interference risks, energy efficiency waste, and maintenance safety hazards in existing battery and communication integrated systems.
