Abstract

The invention discloses a composite superconducting plate heat pipe power battery heat management system. The system is characterized in that the system comprises a shell, at least one power battery box is arranged in the shell, and each power battery box comprises a box body, wherein a plurality of composite superconducting plate heat pipe heat sinks and power batteries are arranged in the box body at intervals. According to the composite superconducting plate heat pipe power battery heat management system, the quick heat conducting feature of composite superconducting plate heat pipes is adopted, the evaporation ends of the heat pipes make tight contact with the power batteries to absorb the heat generated by the batteries, and the heat is transmitted to condensation ends from the evaporation ends and dispersed through the natural convection or air cooling; by means of the structure, it can be guaranteed that the temperature difference among the batteries is smaller than 2 DEG C, temperature rising is controlled within 10 DEG C, the service life of the batteries is prolonged, and the stability of the batteries is improved. The composite superconducting plate heat pipe power battery heat management system is simple in structure, wide in applicability and suitable for large-capacity power batteries, and battery box sets are convenient to assemble, increase and decrease.

Description

technical field [0001] The invention relates to a composite superconducting flat plate heat pipe power battery thermal management system, which is mainly used in the technical fields of transportation power supply, power storage power supply, mobile communication power supply, aerospace and military power supply and the like. Background technique [0002] With the wide application of power batteries, rapid battery charging and the impact of the use environment lead to the reduction of power battery life and the continuous occurrence of failures. Therefore, a device is required to thermally manage the power battery to ensure that the battery can work normally. [0003] At present, the battery cooling system mainly uses the internal thermal cycle of the battery itself and the air cooling method of the battery pack. This cooling method can only relieve the battery temperature from being too high (≥50°C), but it cannot change the temperature uniformity of the battery or cause the...
