A multi-mode temperature management system for internal combustion engine vehicles

Abstract

The invention provides an internal combustion engine automobile multi-mode temperature management system. The system comprises an air conditioning system and an internal combustion engine temperaturemanagement system, wherein the air conditioning system can independently heat and refrigerate a compartment, and the internal combustion engine temperature management system can independently heat andrefrigerate an internal combustion engine. The multi-mode temperature management system is advantaged in that communication and disconnection of the air conditioning system and the internal combustion engine temperature management system are controlled through pipelines and valves, the multi-mode temperature management system dynamically switches the internal combustion engine temperature management modes according to the real-time temperature of the internal combustion engine, heat dissipation efficiency is higher, the engine warming speed is higher, and temperature management is more flexible.

Description

technical field [0001] The invention relates to the technical field of thermal management of internal combustion engine vehicles, in particular to a multi-mode temperature management system for internal combustion engine vehicles. Background technique [0002] The existing internal combustion engine vehicle temperature management has the following technical problems: [0003] (1) The existing internal combustion engine vehicles only cool down the internal combustion engine through the radiator of the water tank, which has low cooling efficiency and is greatly affected by the environment. In the case of relatively harsh operating environment, such as high compression ratio of internal combustion engine, heavy vehicle load, high ambient temperature, etc., it is easy to cause overheating of internal combustion engine and boiling of cooling water tank; [0004] (2) When the existing internal-combustion engine vehicle is started in an extremely low temperature environment, probl...

AI Technical Summary

Problems solved by technology

[0003] (1) Existing internal combustion engine vehicles only cool down the internal combustion engine through the water tank radiator, which has low cooling efficiency and is greatly affected by the environment

In the case of relatively harsh operating environment, such as high compression ratio of internal combustion engine, heavy vehicle load, high ambient temperature, etc., it is easy to cause overheating of internal combustion engine and boiling of cooling water tank;

[0004] (2) When the existing internal combustion engine vehicle is started in an environment with extremely low temperature, it is prone to problems such as severe piston wear and even fracture of the piston connecting rod

[0005] (3) The existing air-conditioning system for internal combustion engine vehicles is only aimed at cooling the compartment, and is not combined with the cooling function of the internal combustion engine;

[0006] (4) The existing working mode of the internal combustion engine cooling system only has two modes of coolant small circulation warm-up and water tank heat dissipation, and it is difficult to select an appropriate temperature management mode according to the temperature of the internal combustion engine
