Problems solved by technology

The downside of analog output ICs is the limited temperature range (55°C-150°C) and the need for an external reference source
[0015] It can be seen that in the prior art, when measuring the temperature of the stator of the vehicle generator, an external temperature sensor is usually used for temperature sensing, and the temperature sensing often cannot guarantee direct and effective

Embodiment Construction

[0050] In the following, the same reference numerals refer to the same elements.

[0051] figure 1 A system block diagram showing a generator cooling cycle system according to the present invention. Such as figure 1 As shown, the generator cooling cycle system includes chips, diodes, engine management module (EMS), and fans.

[0052] exist figure 1 In the generator cooling cycle system shown, the chip is embedded in the generator, so the temperature of the chip can reflect the stator temperature of the generator. The diode is sensitive to temperature, therefore, the diode can be used as a temperature sensor, and the temperature value of the chip can be detected by the diode. The temperature value is fed back to the engine management module, and then, based on the fed back temperature value, the engine management module can control the speed of the fan to cool the generator.

[0053] In particular, the LIN regulator in the generator is responsible for the communication ...

Abstract

The invention discloses a cooling circulatory system for an automobile generator. A chip is embedded in a generator stator to directly measure the temperature of the stator; a diode is arranged in the chip and is used for measuring the temperature value of the chip, and the temperature value is fed back to an engine management module; based on the fed-back temperature value, the engine management module controls the rotation speed of a fan to cool the generator, thereby reducing the temperature of the generator and reducing the temperature of the chip; and the temperature value of the chip after temperature reduction is then fed back to the engine management module again, and the engine management module controls the rotation speed of the fan again based on the temperature value obtained after temperature reduction. Therefore, system development cost is reduced, the whole system is simplified, and reliability is enhanced. Besides, The invention also provides a corresponding system and method for estimating the temperature of stator.

Description

technical field [0001] The present invention relates to a cooling cycle system for an automobile generator and a system and method for estimating the stator temperature of an automobile generator. Background technique [0002] The car cooling cycle system is very important to the car. Especially in summer, especially in the case of frequent traffic jams in the city, it is a severe test for the automobile cooling circulation system. If the cooling circulation system has poor circulation or the cooling water is too dirty, there will be problems when encountering traffic jams. At this time, since the cooling air blown in from the front of the car cannot be obtained by increasing the speed of the vehicle, all cooling work in the generator room must be completed by the cooling circulation system. An unhealthy cooling system in a vehicle can accelerate other problems due to high heat, such as failure of the battery and power generation system. And if the battery and power gener...
