AI Technical Summary

Technical Problem

Hybrid vehicle radiators face high energy consumption and low heat dissipation due to a single electronic fan controlling multiple cooling components, leading to overheating issues.

Method used

Implement a thermal management system with separate fans for different cooling components (intercooler and radiator, condenser) and precise control of fan rotational speeds based on temperature sensors and controllers.

Benefits of technology

Enhances heat dissipation efficiency, reduces energy consumption, and extends the lifespan of cooling components by independent control of fan speeds, maintaining optimal operating temperatures.

Abstract

A vehicle (200) having a thermal management system (100). The thermal management system (100) of the vehicle (200) includes an engine cooling system (10), an air conditioning system (30), and a low-temperature cooling system (20). The engine cooling system (10) includes an engine (11), an intercooler (12), a first radiator (15), and a first fan (13). An air outlet end (121) of the intercooler 12 communicates with an intake manifold (111), and an air inlet end (122) of the intercooler (12) communicates with a supercharger (112). The first fan (13) is used to dissipate heat from the intercooler (12) and the first radiator (15). The low-temperature cooling system (20) includes a second radiator (22) and a second fan (24). The second fan (24) is used to dissipate heat from the second radiator (22) and the condenser (33).
