Abstract

The invention discloses a design method of a vehicle cooling system, which comprises the following steps: when an engine of a target vehicle model is in a limit working condition, obtaining the required heat dissipating capacity, the required water flow, the required cooling air quantity, the heat exchange temperature difference and the head-on air speed of a radiator, the limit working condition comprising a maximum torque point working condition or a maximum power point working condition; determining the windward area of the radiator according to the required cooling air volume and the head-on air speed; determining a target radiator according to the required water flow, the required heat dissipating capacity, the heat exchange temperature difference, the head-on wind speed and the windward area; according to the scheme, a novel forward design scheme of the cooling system is provided, and compared with a one-dimensional simulation design scheme, the problem that the development efficiency is reduced due to the fact that the performance of a radiator is not matched with that of a new vehicle model due to incorrect use of general design parameters is solved.

Description

technical field [0001] The present application relates to the field of vehicle technology, in particular to a design method and device for a vehicle and its cooling system. Background technique [0002] Radiator, fan, and water pump are the main components of the car cooling system. In a high-temperature environment, the heat generated by the engine needs to be dissipated through the cooling system to ensure the normal operation of the engine. How to complete the design and development of the cooling system through the means of forward design in the early stage of model development has always been the top priority of the development and design of vehicle thermal management for various car companies. [0003] At present, a method of forward design of cooling system is to apply fluid dynamics analysis software to conduct one-dimensional simulation of cooling system, so as to simulate the pressure distribution, flow distribution and temperature distribution of cooling system in...
