Electrombile thermal management system

Abstract

The invention relates to an electrombile thermal management system which is combined with cooling of a power device and belongs to the layout field. The electrombile thermal management system comprises a motor cooling liquid circulation system, an air conditioner refrigerating fluid circulation system and a battery pack cooling liquid circulation system. The battery pack cooling liquid circulation system comprises a second water pump, a three-position four-way water valve, a fuel heater, a two-position three-way water valve, a battery pack and a second water tank, wherein the second water pump, the three-position four-way water valve, the fuel heater, the two-position three-way water valve, the battery pack and the second water tank are sequentially connected in a circulated mode, two output ends of the three-position four-way water valve are connected with the input end of the air conditioner refrigerating fluid circulation system and the input end of a battery pack radiator respectively, one output end of the two-position three-way water valve is connected with the input end of a heater core, the output end of the battery pack radiator, the output end of the heater core and the output end of the air conditioner refrigerating fluid circulation system are all connected with the input end of a battery pack, and the heater core is arranged on one side of an electrombile carriage. By means of the electrombile thermal management system, cooling on a motor, a motor controller and a vehicle-mounted charging module can be achieved, and refrigeration and heating on an in-vehicle air conditioner system and temperature control over the battery pack can be achieved.

Description

technical field [0001] The invention relates to a system in the field of arrangement combined with the cooling of a power unit, in particular to a heat management system for an electric vehicle. Background technique [0002] After the outbreak of the three global oil crises in the 1970s, various multinational automobile companies began to develop various types of electric vehicles. Through the three five-year plans of "Eighth Five-Year Plan", "Ninth Five-Year Plan" and "Tenth Five-Year Plan", my country has invested a lot of manpower, material resources and financial resources in the research and development of electric vehicles, and has achieved a series of scientific research results. With the global With the deepening of the energy crisis, the depletion of oil resources and the increasing harm of air pollution and global temperature rise, governments and automobile companies in various countries generally recognize that energy saving and emission reduction are the main dir...
