A new energy vehicle integrated thermal management system and its working method

Abstract

The invention discloses an integrated thermal management system for a new energy vehicle and a working method thereof. The evaporative cooling system of the source and the circulating heat exchange system for heat exchange, the circulating heat exchange system is provided with a first heat exchanger, and exchanges heat with the evaporative cooling system and the warm core heating system through the first heat exchanger; The present invention realizes the cooling of the battery, electric control equipment and passenger cabin under the cooling condition by controlling the opening and closing of the valves inside and between the systems, and the heating of the passenger cabin and the preconditioning of the battery and the electric control equipment under the heating condition. Heat preservation, heat preservation and waste heat recovery, incorporating automatic driving and wireless charging modules into the thermal management system, high utilization rate of waste heat, good energy saving effect, and cost reduction. The heat pump mode of the electric heat pump compressor has low operating temperature requirements and can meet low temperature conditions. need.

Description

technical field [0001] The invention relates to the technical field of vehicle thermal management, in particular to a new energy vehicle integrated thermal management system and a working method thereof. Background technique [0002] Nowadays, with the gradual popularization of electric vehicles, the problems they face have gradually become prominent. Compared with traditional vehicles, new energy vehicles have no engine heat source, and rely on electric heating for heating, which consumes a lot of energy. At the same time, the battery is discharged under low temperature conditions. The efficiency is low, and the battery temperature is too high in summer and it is easy to spontaneously ignite, and it will also cause problems with charge and discharge efficiency. [0003] At present, the heating and battery heating of electric vehicles mainly adopt electric heating solutions. The efficiency of electric heating is low, and the cruising range of electric vehicles is greatly re...
