Problems solved by technology

For example, the air circulation of the water tank is not smooth due to scale, improper heat sink or dust and other sundries, and the fan does not turn, etc., which will lead to high temperature at the outlet of the water tank, which in turn will increase the operating temperature of the engine and affect its working performance.

Abstract

The invention relates to an alarm circuit for poor heat dissipation of an automobile engine water tank. The automobile engine radiator poor heat dissipation alarm circuit includes a power supply branch, a temperature measurement branch and an alarm branch connected in sequence. The power supply branch provides working voltage, and the temperature measurement branch measures the inlet and outlet temperatures of the water tank. When the temperature at the inlet or outlet of the water tank is too high, the alarm branch will alarm. When the inlet temperature of the water tank of the automobile engine is too high or the outlet temperature is too high, the alarm light will be on, prompting the driver or maintenance personnel to check the engine cooling system in time to prevent the engine from overheating and affecting the engine's working performance.

Description

technical field [0001] The invention relates to an alarm circuit, in particular to an alarm circuit for poor heat dissipation of an automobile engine water tank. Background technique [0002] The normal operating temperature of the automobile engine is about 90°C-100°C, too high or too low will have a great impact on the working performance of the engine, which is adjusted through the engine's cooling system. The engine cooling system mainly includes a radiator (also called a water tank), a fan, and a water pump. The cooling water is circulated in the system through the water pump, and the heat absorbed by the cooling water on the engine body is dissipated through the water tank. When the fan rotates, it can strengthen the water tank. cooling effect. As long as the engine is running, the water pump will work; the work of the fan is only related to the working temperature of the engine. Generally, the fan turns when the working temperature of the engine is higher than 90°C, ...
