Problems solved by technology

The traditional control method of vehicle radiator is a kind of extensive control method, it is only for the purpose of not "boiling" the engine, it does not distinguish between different working conditions of the engine, and cannot accurately control heat dissipation, so it cannot effectively Solve the requirements of engine heating at low temperature and heat dissipation at high temperature
The power of the vehicle radiator comes from the engine, and the heat dissipation cannot be controlled according to the actual working conditions, which makes the traditional heat dissipation system increase unnecessary power consumption, which is not conducive to energy saving
On the other hand, the traditional vehicle radiator and its control method have also brought other problems, such as long-term operation of the fan. After a long period of operation, the radiator with only one large-diameter cooling fan is more prone to failure, that is, the failure rate On the other hand, the fan will make noise when it is running. Because the traditional vehicle radiator does not control the heat dissipation accurately, it does not distinguish the different working conditions of the engine, so the large-diameter fan can be used in various working conditions Under the condition of high rotation speed or heat dissipation without the need for heat dissipation, the noise of the fan is relatively high.

Abstract

The invention relates to arrangement combined with cooling of a vehicle power device, in particular to a vehicle radiator. The invention further relates to a control method of the radiator. By means of the radiator, the heat dissipation capacity can be controlled precisely, the noise is lower, and the failure rate is lower. By means of the control method, the heat dissipation capacity can be controlled precisely, more energy is saved, and the noise is lower. The radiator comprises a switch clutch and at least two electromagnetic fan clutches. Input shafts of all the electromagnetic fan clutches are connected with an output shaft of the switch clutch through transmission devices. Output shafts of the electromagnetic fan clutches are connected with fans respectively. The total heat dissipation capacity of all the fans can be controlled by controlling the state of the switch clutch and the states of the electromagnetic fan clutches according to actual heat dissipation requirements, and the radiator and the control method can be applied to vehicle heat dissipation systems.

Description

technical field [0001] The present invention relates to an arrangement and a method in connection with the cooling of a vehicle power unit, in particular to a vehicle radiator. The invention also relates to a control method of the radiator. Background technique [0002] With the continuous development of the automobile industry, users' requirements for vehicle cooling systems are gradually developing in the direction of reliability, energy saving, precision and low noise. A traditional vehicle radiator dissipates heat through a large-diameter cooling fan driven by the engine through a pulley and a transmission belt. The traditional control method of vehicle radiator is a kind of extensive control method, it is only for the purpose of not "boiling" the engine, it does not distinguish between different working conditions of the engine, and cannot accurately control heat dissipation, so it cannot effectively Solve the requirements of heating up the engine at low temperature a...
