Embodiment Construction

[0027] The distributed off-road vehicle powertrain heat exchange system provided in this embodiment includes a modular distributed heat exchange device installed in the engine compartment, consisting of a radiator module, an intercooler module and a condenser module. Among them, the radiator module is installed between the front air inlet and the engine, including the radiator and the radiator fan installed behind the radiator. The radiator fan is driven to rotate through the clutch drive device installed on the engine, and the engine drives the fan through the clutch. Drive the cooling airflow to complete the heat dissipation of the cooling system. The intercooler module and condenser module are symmetrically arranged on the left and right, and are installed on both sides of the engine, between the front air inlet and the firewall, and arranged in a distributed manner with the engine radiator. The intercooler module includes the intercooler and The intercooler fan installed a...

Abstract

The invention relates to a distributed off-road vehicle powertrain heat exchange system and its control method. The rapid response of the fan drive is controlled by a wading induction device to realize system protection so as to keep the performance of the whole vehicle from attenuating and improve the survivability in complex environments. . Multiple sets of control strategies are stored in the controller to realize intelligent or manual switching of working conditions such as no-load, medium-load, heavy-load, and climbing to improve power performance; through PID closed-loop control, the best working conditions of each heat exchanger, Ensure that the engine intake air temperature / air intake volume, coolant temperature, and engine oil temperature are in the best state, thereby greatly reducing fuel consumption and system noise, and improving engine performance and vehicle replenishment cycle.

Description

technical field [0001] The invention relates to a vehicle powertrain heat exchange system and a control method, in particular to a distributed powertrain heat exchange system for an off-road vehicle and a control method thereof, belonging to the technical fields of vehicle engineering and engineering thermophysics. Background technique [0002] Off-road vehicles require high passability, reliability, and weather resistance, as well as high protection, modification and maintenance convenience, shock absorption and noise reduction, and other performances. The requirements for environmental friendliness are also getting higher and higher. Improve fuel economy as much as possible under the premise of power. [0003] Powertrain heat exchange device, the existing mature technology is the central, inclined, series heat exchanger and curved air duct, and the direct fan mode that is mechanically connected to the engine. This patent adopts a method different from that of the prior ar...
