Problems solved by technology

In this way, for the radiator placed at the rear, the temperature difference between the air temperature entering the radiator and the flowing medium inside becomes smaller, so that its heat dissipation capacity decreases, which will make the cooling performance difficult to meet the standard

Abstract

The invention discloses a cooling system of a hybrid off-road vehicle and a control method thereof, which comprises a first cooling module and a second cooling module arranged in an engine compartment, and the first cooling module is vertically arranged on a front hatch close to the engine compartment side, the second cooling module is installed obliquely on the side close to the engine direct-connected fan in the engine compartment, an electronically controlled fan is arranged between the first cooling module and the second cooling module, and a fan is arranged between the first cooling module and the second cooling module. Electrically controlled shutter device installed on the upper hatch of the engine nacelle. The invention is simple in structure and easy to use. It not only satisfies the cooling standard of each high-power-density radiating component in all cooling modules, but also ensures that each high-power-density radiating component works in a required temperature range.

Description

technical field [0001] The invention relates to an off-road vehicle cooling system and a control method thereof, belonging to the technical field of off-road vehicle cooling systems, in particular to a hybrid off-road vehicle cooling system with at least two sets of cooling circulation loops and at least two independent cooling radiators. its control method. Background technique [0002] The cooling system of hybrid off-road vehicles generally includes the following parts: engine radiator, that is, the radiator for the cooling circuit of the engine; electric part radiator, such as battery packs, motors, electrical controllers, etc. The radiator; the condenser is used for the refrigeration of the automobile air conditioner and is placed at the front for heat dissipation. In addition, in some cases, a gearbox cooling oil cooler with a gearbox cooling circuit placed at the front end may be provided. If the engine uses a supercharged engine, an intercooler for charge air coolin...
