Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles and relates to an auxiliary cooling system for a fuel vehicle engine, in particular to a controllable auxiliary cooling system for a fuel vehicle engine. Background Art

[0002] When the engine is working, the combustible mixture burns in the cylinder, and its operating temperature is as high as 2000°C, and the instantaneous temperature can reach about 3000°C. If it is not properly cooled, the engine will overheat, resulting in reduced charging efficiency, abnormal combustion, oil deterioration, increased wear of parts, and sometimes even accidental damage such as machine parts being stuck or burned. However, if it is overcooled, the viscosity of the oil will increase due to the cylinder temperature being too low, the friction loss will increase, the fuel atomization will be poor, the power will decrease, the heat dissipation loss will increase, and the lubrication performance will deteriorate. Therefore, the engine must be properly cooled to ensure that the engine is always operating at the most suitable temperature.

[0003] The main function of the cooling system is to dissipate part of the heat absorbed by the heated parts in a timely manner to ensure that the engine operates at the most suitable temperature.

[0004] The following problems exist during the application process:

[0005] The engine cooling system meets the cooling requirements when the vehicle is driving under normal road conditions, but the cooling system cannot meet the requirements under extreme conditions such as when the vehicle is climbing a slope for a long time, resulting in high engine temperature problems;

[0006] To solve this problem, traditional vehicles generally improve the flow of cooling system-related components, such as: 1. Increasing the cooling area of ​​the radiator / intercooler; 2. Improving the air intake of the vehicle's front cooling system; 3. Increasing the engine water pump flow, etc.

[0007] The solution of traditional vehicles will affect the vehicle shape, increase the fuel consumption of the whole vehicle, cause excessive cooling of the engine under normal road conditions, affect the vehicle's passability, increase costs, etc. Therefore, it is necessary to design a controllable engine auxiliary cooling system.

Therefore, they should not be understood as limitations on the embodiments of the present application.

[0024] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0025] like Figure 1 As shown, the controllable engine auxiliary cooling system of the utility model includes an air storage cylinder, a first pipeline, a water tank, a second pipeline, and a spray pipe.

[0026] The air storage cylinder is connected to the water tank through a first pipeline.

[0027] The first pipeline is a gas circuit, including a first gas pipe, a first ball valve, and a second gas pipe arranged in sequence; one end of the first gas pipe is connected to the gas storage cylinder, and the other end is connected to the gas inlet end of the first ball valve; one end of the second gas pipe is connected to the gas outlet end of the first ball valve, and the other end is connected to the water tank. The first ball valve is used to adjust the gas flow of the first pipeline, and at the same time, an air pressure regulating valve is arranged between the first gas pipe and the first ball valve to adjust the air pressure of the first pipeline, so as to achieve the purpose of adjusting the water tank pressure.

[0028] The water tank is connected to the spray pipe through a second pipeline, and the water tank is provided with an air inlet and a high-pressure water outlet.

[0029] The second pipeline is a water circuit, including a first water pipe, a second ball valve, and a second water pipe. One end of the first water pipe is connected to the water outlet of the water tank, and the other end is connected to the inlet end of the second ball valve; one end of the second water pipe is connected to the outlet end of the second ball valve, and the other end is connected to the spray pipe; wherein the first water pipe and the second water pipe are both soft hoses, and the second ball valve is used to adjust the water flow of the second pipeline.

[0030] The spray pipe is fixed on the top of the radiator or intercooler, and the spray outlet is evenly arranged along the lower wall of the pipe body. The spray pipe can be made of steel pipe structure or other hard water pipe, and the length matches the radiator or intercooler, which can be as follows: Figure 1 The straight pipe arrangement from left to right along the top of the radiator or intercooler is shown, and the curved pipe arrangement can also be used. The spray outlet holes are evenly arranged along the axis from the lower side wall of the steel pipe, so that the spray pipe discharges water in the direction close to the radiator or intercooler, and sprays on the radiator or intercooler shell to physically dissipate the heat of the radiator or intercooler. The spray outlet flow rate is adjustable and is adjusted by the second ball valve in the second pipeline to control the cooling effect.

[0031] Another technical solution of the utility model is a fuel vehicle having the above-mentioned controllable engine auxiliary cooling system.

[0032] The working principle of the controllable engine auxiliary cooling system of the utility model:

[0033] When the vehicle is in extreme working conditions, the heat dissipation of the engine cooling system radiator cannot meet the engine heat dissipation requirements. At this time, the controllable engine auxiliary cooling system can be turned on for cooling. The first step is to adjust the air pressure regulating valve 5 to between 0.1Mpa and 0.15Mpa; the second step is to open the first ball valve 6 to fill the compressed gas of the air cylinder 3 into the water tank 1 to pressurize the water tank 1 (this must be done when the engine is parked and not turned off to ensure driving safety); the third step is to wait for the air pressure in the water tank 1 to stabilize, open the second ball valve, and the water in the pressurized water tank 1 flows through the water pipe to the third water pipe (steel pipe) above the radiator, and the water in the third water pipe (steel pipe) flows to the top of the radiator 11 through the drainage hole 101, and the radiator 11 is physically cooled. After preparation, the vehicle can drive normally. The controllable engine auxiliary cooling system can control the auxiliary cooling effect by adjusting the flow of cooling water through the second ball valve.

[0034] The controllable engine auxiliary cooling system of the utility model is reasonably designed, and uses the method of physical cooling to solve the problem of proper cooling of the engine under extreme working conditions, ensuring that the engine always works at the most suitable temperature. The purchase cost is low, the control is simple, and the performance is reliable; the controllable engine auxiliary cooling system can be started and stopped according to the driver's driving intention.
