Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and in particular relates to a compartmentalized thermal management system for battery systems and communication equipment. Background Technology

[0002] The existing battery and communication equipment integration systems mainly adopt the following solutions for thermal management: (1) Integrated temperature control design: The battery module and the communication equipment share the same thermal management system (such as water cooling 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 the problems of 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 the equipment compartment, but physical isolation of the thermal management system has not been achieved.

[0003] However, the above thermal management methods have the following limitations: (1) Risk of thermal coupling interference: When the battery and equipment share the heat dissipation system, the heat of high-temperature electronic components (such as communication chips) may be conducted in reverse to the battery compartment, accelerating battery aging (the life decay rate of lithium iron phosphate batteries increases by 300% when the temperature is above 60°C). (2) Energy waste: Traditional integrated temperature control needs to maintain the low temperature of the entire system at all times, while communication equipment only needs intermittent high-efficiency heat dissipation, resulting in redundant energy consumption. (3) Maintenance safety hazards: Fire extinguishers cannot accurately locate the fire source, and the equipment compartment cables may be ignited when the battery thermally runs away.

[0004] Based on this, the purpose of this utility model is to provide a compartmentalized thermal management system for battery systems and communication equipment, which aims to solve the problems of thermal coupling interference risk, energy waste and maintenance safety hazards in existing integrated battery and communication systems.
