Abstract

The invention discloses a new energy electric vehicle thermal management system with full-climate multi-mode switching function, including a cooling / heating system and a battery pack with full-climate multi-mode switching function; the cooling / heating system includes air compression machine, four-way reversing valve, gas-liquid separator, expansion valve, heat exchanger, circulation pump, solenoid valve group, three-way valve group, finned heat exchanger group, battery pack including battery box, pressure equalization split flow compound There are several battery cells in the battery box, and a regenerative active / passive combined liquid temperature control unit is arranged between every two battery cells. The new energy electric vehicle thermal management system of the present invention has multiple working modes, which is convenient for switching under different climatic conditions such as hot and cold, and rationally combines single-phase forced convection heat transfer, solid-liquid phase conversion heat and gas- The multiple advantages of liquid phase conversion heat can meet the requirements of interior temperature regulation and power battery temperature control and temperature uniformity.

Description

technical field [0001] The invention relates to a thermal management system for a new energy electric vehicle, in particular to a thermal management system for a new energy electric vehicle with an all-climate multi-mode switching function, and belongs to the technical field of new energy electric vehicles. Background technique [0002] With the increasingly serious energy crisis and environmental pollution, pure fuel vehicles are no longer the most ideal means of transportation, and countries have successively planned to ban the sale of fuel vehicles. New energy electric vehicles are driven by electricity, and the electric energy can come from renewable clean energy such as solar energy and wind energy, which reduces the consumption of traditional fossil fuels. Therefore, the development of new energy electric vehicles is one of the important measures for the automotive industry to save energy and reduce emissions and achieve sustainable development. one. The further devel...
