Zero energy consumption new energy automobile heat management system

Abstract

The invention discloses a zero energy consumption new energy automobile heat management system. The zero energy consumption new energy automobile heat management system is characterized in that the zero energy consumption new energy automobile heat management system includes an air compression system, a refrigeration / heating system, a battery box body and a coil pipe. An air compression device inthe air compression system is driven by a first wind energy conversion mechanism. A compression device in the refrigeration / heating system is driven by a second wind energy conversion mechanism. An evaporator in the refrigeration / heating system is connected with an inlet end of the battery box body. The air compression system is connected with the evaporator. A battery pack is installed in the battery box body. Interspaces of the battery pack are filled with phase-change materials. One end of the coil pipe is connected with the inlet end and the outlet end of the battery box body separately through pipes. The other end of the coil pipe communicates with an air outlet hole in an automobile. The zero energy consumption new energy automobile heat management system has the advantages that theheat management system does not need to consume electrical energy, and heat management to a driving battery and temperature regulation to the automobile environment can be conducted simultaneously.

Description

technical field [0001] The invention relates to a thermal management system of a new energy vehicle, in particular to a zero energy consumption thermal management system of a new energy vehicle. Background technique [0002] With the development of power battery technology and the increasingly serious environmental pollution problems, new energy vehicles have developed very rapidly in recent years, and in the near future, new energy vehicles will gradually replace traditional fuel vehicles. In new energy vehicles, the power battery must be maintained in a reasonable temperature range, otherwise it will affect the service life of the battery. Therefore, when the temperature of the power battery is too low, it needs to be heated, and when the temperature is too high, it needs to be cooled. Strict thermal management. In addition, the air conditioning system in new energy vehicles needs to consume battery power, which reduces the endurance of new energy vehicles. [0003] At p...

Problems solved by technology

Active cooling includes air cooling and liquid cooling, which can quickly transfer the heat of the power battery pack to the outside world, but the pumps or fans in the active cooling system need to consume electricity; passive cooling mainly uses phase change materials, which have no moving parts. The structure is simple, energy-saving and environmentally friendly, and can absorb a large amount of heat to keep the temperature relatively stable, but it cannot transfer the absorbed heat to the outside world
