Description

technical field [0001] The invention belongs to the technical field of antifreezing and cooling of automobiles, and in particular relates to a device for antifreezing of an automobile fuel supply system and cooling of a brake system. Background technique [0002] 1. For automobiles in the cold weather in the north in winter, when the fuel supply system is under the low temperature environment below -5°C, the technical indicators such as the kinematic viscosity and flash point of the diesel oil will be seriously reduced, resulting in no fuel, bad combustion, and harmful emissions. Even if the most expensive -35# diesel is used, its high energy consumption and high emissions are still unavoidable. A large amount of harmful emissions is one of the main causes of severe smog in northern China; therefore, diesel engines in winter in the north Anti-freezing and heating up the oil supply system is an important technical measure to reduce energy consumption and reduce harmful emissi...

[0002] 1. For automobiles in the cold weather in the north in winter, when the fuel supply system is under the low temperature environment below -5°C, the technical indicators such as the kinematic viscosity and flash point of the diesel oil will be seriously reduced, resulting in no fuel, bad combustion, and harmful emissions. Even if the most expensive -35# diesel is used, its high energy consumption and high emissions are still unavoidable. A large amount of harmful emissions is one of the main causes of severe smog in northern China; therefore, diesel engines in winter in the north Anti-freezing and heating up the oil supply system is an important technical measure to reduce energy consumption and reduce harmful emissions; 2. In the braking system of a car, brake pads are the most critical safety parts, and all braking effects are determined by the brake pads Therefore, good brake pads are the patron saint of the driver and the car; brake pads are mainly divided into drum brakes and disc brakes. , When the car goes downhill for a long time, the temperature of the friction pads on the brake pads rises rapidly. Generally, the temperature of the brake pads for non-continuous braking is about 130°C, and the temperature for long-distance braking and continuous braking rises sharply, about 200-300°C. If it exceeds the test limit of 350°C, the braking ability may be lost, causing a great safety hazard; too high temperature is the main reason for the brake pads to decline, which directly affects the braking performance, so the cooling of the brake pads becomes particularly important; in addition : 1. In the past, the fuel supply system was heated by electric heating or automobile exhaust preheating and heating. First, it was uneconomical, and starting the car increased fuel consumption; second, it was inconvenient, and the effect could not be guaranteed after the car stopped; second, it was not To be safe, the circuit and oil circuit should be completely separated; 2. The cooling technology of the brake pads has always been the water tank spray cooling method. First, it wastes water resources; second, the water tank increases the load of the vehicle and increases fuel consumption; third. In summer, the water temperature of the water tank is high and the cooling effect is not obvious; Fourth, in winter, the cooling effect of spraying water on the road leads to the formation of ice bands on the road surface, which increases safety hazards; The cooling device of the brake system is of great significance
