How much do you know about GEELY Cooling Fans?

As a GEELY Cooling Fans Supplier China, share with you. The cooling fan is an important part of the vehicle cooling system. The performance of the fan directly affects the heat dissipation effect of the engine, which in turn affects the performance of the engine. If the fan is not selected properly, it will result in insufficient or excessive cooling of the engine, resulting in deterioration of the engine working environment, which in turn affects the performance and service life of the engine. In addition, the power consumed by the fan accounts for about 5% to 8% of the output power of the engine. In the pursuit of environmental protection and low energy consumption, the fan has also attracted increasing attention. In traditional fan matching, technicians often choose fans by analogy, that is, similar cooling requirements select the same fan. If analogy is not possible, the fan will be selected with reference to factors such as fan installation requirements, engine model, and vehicle working environment. . This method lacks pertinence and the matching effect depends largely on the experience of technical personnel. The fans selected in this way can often only meet the cooling requirements of the system and cannot be optimized in terms of power consumption.

Choose the matching fan according to the determined cooling system, that is, perform matching analysis on each fan separately, and obtain the fan that meets the cooling requirements and has the lowest power consumption through comparison.

When the fan runs stably in the cooling system, the static pressure is equal to the resistance of the cooling system, and the flow rate at this time is the matching flow rate of the fan and the cooling system. To study the matching between the fan and the cooling system, first determine the matching flow of the fan and the cooling system, and then determine whether the cooling power meets the requirements of the cooling system at this flow, and finally select the one with the lowest power consumption from the fans that meet the requirements.

The performance of GEELY Cooling Fans at a certain speed of a certain system is called the operating point of the fan. In the matching analysis, it is impossible to analyze all the working conditions of the engine one by one. Usually, the operating point of the fan is determined and analyzed only for the most demanding working conditions with cooling power. When the cooling power of the fan can still meet the requirements under this working condition, you can Use this fan. When the engine power is at its maximum, its calorific value is also the largest, but this kind of working condition is rarely encountered, and with the increase of the rotational speed, the increase of the air volume is greater than that of the calorific value, so this study chooses the maximum engine torque Match analysis.

A method for matching the cooling fan of the vehicle cooling system is based on the analysis and calculation of the resistance of the cooling system of the diesel locomotive and the performance parameters of the cooling fan.
