Energy Storage Tubes with Heat Pipe Thermal Management are heat exchange components that rely on internal working fluid phase change for efficient heat conduction. They are matched with lithium battery energy storage modules, container energy storage, household energy storage and other equipment. The core functions include temperature control and heat dissipation, low-temperature preheating, waste heat recovery, safe flame retardancy, and adaptability to multiple energy storage scenarios
1、 Efficient heat dissipation and elimination of local hotspots for battery modules (core purpose)
Adhere to the side/bottom of the battery cell, quickly dissipate the heat generated by high rate charging and discharging, solve the problem of local high temperature hotspots in high-power energy storage batteries, reduce the peak temperature of a single battery cell by 6-10 ℃, and avoid the chain spread of uncontrolled heating caused by a single point exceeding 60 ℃.
By relying on the super strong isothermal conductivity, the temperature difference of the entire cluster of batteries is controlled within ± 1 ℃, significantly reducing the capacity degradation and inconsistency caused by temperature difference, and extending the cycle life of the energy storage system.
Suitable for high-energy density large battery cells (280Ah/300Ah lithium iron phosphate), it compensates for the shortcomings of weak heat dissipation in traditional air cooling and large temperature difference in single-sided liquid cooling. It is often combined with liquid cooling and air cooling to form a composite thermal management system.
2、 Uniform preheating of batteries in low-temperature environments
When the temperature of outdoor container energy storage in the northern region is below 0 ℃ in winter:
Reverse heat transfer through heat pipes transfers the waste heat from PCS, heat dissipation systems, and equipment to low-temperature battery cells, achieving synchronous heating of the entire battery pack and eliminating the risk of uneven heating and cooling of battery cells and lithium deposition short circuits.
No need for additional high-power heating film, reducing low-temperature start-up energy consumption and ensuring normal charging and discharging in the sub zero environment of the energy storage power station.
3、 Energy storage system waste heat recovery and reuse
Collect low to medium temperature waste heat from batteries and inverters at 40-80 ℃, and export it outside the energy storage cabinet through heat pipes. In winter, provide heating for the energy storage operation and maintenance room and equipment control cabinet; Preheating fan and BMS electronic control to avoid low-temperature freezing damage.
Large scale energy storage power stations can collect waste heat from multiple cabinets and support low-temperature waste heat power generation, achieving energy cascade utilization and reducing overall power consumption losses of the station.
4、 Energy conservation and consumption reduction, reducing the load on refrigeration equipment
During spring and autumn, when the ambient temperature is low at night, the passive natural heat dissipation of the heat pipe takes priority, significantly reducing the start-up time of air conditioning and liquid cooling units; The annual energy-saving rate of the container energy storage heat pipe scheme can reach 30%~66%, significantly reducing the cost of energy storage and heat dissipation.
Moving parts such as waterless pumps and compressors, heat pipes themselves have almost no energy consumption, low long-term operation and maintenance costs, and no risk of liquid leakage.
5、 Block the spread of thermal runaway and enhance energy storage safety
When the heat pipe is used together with aerogel and phase change material, a partition thermal resistance barrier can be formed; After a single battery loses control of heat and catches fire, it restricts the rapid conduction of high temperature to adjacent cells, delays and blocks the spread of heat, reduces the risk of fire and explosion in the energy storage compartment, and meets the fire safety regulations for energy storage.
6、 Multiple types of energy storage terminal supporting application scenarios
Large scale industrial and commercial/container energy storage: Fangcang energy storage cabinet, grid side energy storage power station, module temperature equalization, waste heat recovery, and year-round energy-saving and heat dissipation;
Household/wall mounted energy storage: small energy storage battery pack, photovoltaic energy storage all-in-one machine, compact space scene ultra-thin micro heat pipe array for heat dissipation;

Special energy storage: ship energy storage, base station backup energy storage, mobile energy storage vehicles, lightweight heat pipes suitable for small equipment compartments.
