Intelligent fan controller

Abstract

The invention provides an intelligent fan controller. An engine rotary speed signal module, an engine water temperature signal module, an engine air temperature signal module, an oil temperature signal module of a speed changing box and a water temperature signal module of a water cooling motor are connected with a signal receiving end of a microcontroller module through a CAN (Controller Area Network) bus device; a battery storage is connected to the microcontroller module; and an output end of the microcontroller module is connected with an alarming indication lamp module and an electric fan. A microcontroller improves mechanical transmission of a traditional engine heat management fan into an electronic control mode so that an oil saving rate is improved by about 20%; and a working mode of the controller, and starting and full-open temperatures of each path of the fan can be realized by an upper computer through CAN communication, so that the same controller not only can be used on a traditional vehicle but also can be used on a new-energy-source vehicle.

Description

technical field [0001] The invention relates to an intelligent fan control device, and relates to a fan controller in engine thermal management systems of large and medium-sized traditional passenger cars, hybrid electric passenger cars and pure electric passenger cars. Background technique [0002] The engine works by burning fuel in the cylinder of the engine to do work to output power to the outside. So the engine is a big heat generating body. Experiments have proved that when the engine works in a constant temperature range, the efficiency ratio of the diesel engine reaches the best. The operation of the engine requires a fan to cool down. The traditional fan is mechanically driven. Although it can achieve a certain effect, the engine consumes a lot and it is not easy to control the temperature within a certain range. Some cooling fans use an electronically controlled fan controller. It can only be fixedly used in traditional vehicles or new energy vehicles. When the ...

The operation of the engine requires a fan to cool down. The traditional fan is mechanically driven. Although it can achieve a certain effect, the engine consumes a lot and it is not easy to control the temperature within a certain range. Some cooling fans use an electronically controlled fan controller. It can only be fixedly used on traditional vehicles or new energy vehicles. When the module needs to switch models, it needs to reprogram the program to switch modes, which is more troublesome to implement
