Intelligent temperature-control cooling module for automobile and control method thereof

Abstract

The invention relates to an intelligent temperature-control cooling module for an automobile and a control method thereof. The module comprises a heat radiator (2), an air protection cover (3), an electrical fan (4) and a control unit (6), wherein the electrical fan (4) with an inwards concave air suction type structure is arranged in an electrical fan installation ort seat (16) on the air protection cover (3); the heat radiator (2) and the electrical fan (4) are connected with the control unit (6); the control unit (6) is connected with a vesical control unit and a vehicle dashboard; and a coolant temperature sensor (8) at a water inlet / outlet of the heat radiator (2) is connected with the control unit (6). According to the method, the real-time changes of cooling water temperature and the rotary speed of the electrical fan (4) are controlled accurately by adopting pulse-width modulation (PWM), and the rotary speed and the cooling intensity of the electrical fan (4) are adjusted and stabilized in real time according to the temperature of the coolant temperature sensor (8) and the feedback of the electrical fan (4), so that accurate temperature control and demand-based cooling arearealized, the aims of saving energy and reducing consumption are achieved, and the comfort in riding is improved.

Description

technical field [0001] The invention relates to an intelligent temperature-controlled cooling module, in particular to an intelligent temperature-controlled cooling module for automobiles and a control method thereof. Background technique [0002] At present, with the continuous improvement of laws and regulations on automobile energy conservation and emission reduction, coupled with the national encouragement policy for the promotion of new energy vehicles, pure electric vehicles, especially pure electric trucks, have emerged as the times require and are favored by the market. However, in the design process of this type of vehicle, higher requirements have been put forward for the energy saving and noise reduction of the cooling system, and the original conventional cooling system composed of a radiator intercooler and a mechanical cooling fan driven by the engine has not met the requirements.

Problems solved by technology

However, in the design process of this type of vehicle, higher requirements have been put forward for the energy saving and noise reduction of the cooling system, and the original conventional cooling system composed of a radiator intercooler and a mechanical cooling fan driven by the engine has not met the requirements. Requirements for use; at the same time, a large number of new high-voltage components are arranged in the original engine compartment, which squeezes the layout space of the cooling system. Therefore, it is also required to improve the structure of the cooling system, rationally use the space and improve the air circulation in the cabin.
