[Problem that the idea aims to solve]

However, in such a conventional example, the wind caused by the running wind 3 or the fan 5 Since it is only cooled by the air conditioner, the cooling performance may be insufficient under high heat dissipation conditions. Also Mud splashed when driving on muddy land may adhere to the core of condenser 2 or radiator 1. The disadvantage is that the heat dissipation performance is extremely reduced. (Especially when mud dries, it can cause clogging. , cooling becomes impossible. )

[0005] The present invention was developed by focusing on such conventional problems. Forced cooling system for vehicles that improves heat dissipation performance by cleaning clogged data. The purpose is to provide

[0006]

[Means to solve the problem]

In order to achieve this purpose, the present invention uses running wind or a fan to drive a radiator or In vehicle cooling systems that cool air conditioner condensers, An injection nozzle that injects water into the radiator or condenser is installed, and this injection nozzle is At the very least, the cooling water temperature of the radiator is below the specified value and the passing air volume is below the specified value. When the cleaning water is sprayed, the water sprayed from the spray nozzle forces the radiator. It is characterized by cooling and cleaning the motor or condenser.

[0007]

[Effect]

The injection nozzle is operated at least when the radiator cooling water temperature is below a predetermined value and the passing air volume is at a predetermined value. When the temperature is below a fixed value, cleaning water is sprayed, and the water sprayed from this spray nozzle strengthens the machine. Temporarily cool and clean the radiator or condenser.

【Example】

As shown in Figure 1, the radiator 1 and the air conditioner are turned off by the wind or fan. In the vehicle cooling system that cools the condenser 2 of the radiator, the radiator 1 and An injection nozzle 10 is provided to inject water into the condenser 2 and the headlamp 11. A spray nozzle 12 for spraying water is provided. The above injection nozzles 10 and 12 are connected to the switching valve 13. It communicates with a water reservoir tank 15 via a pump 14.

The control unit 16 that controls the switching valve 13 includes an output signal S 1 of a water temperature detection sensor ₂₀ of the radiator 1 and an output signal S ₂ of a manual switch 21 having three positions: headlamp, automatic, and manual. , an output signal S ₃ of the sensor 22 for the passing air volume P for clogging detection, an output signal S ₄ of the light amount sensor 23 of the headlamp 11, and an output signal S ₅ of the sensor 24 for detecting the injection pressure of the injection nozzle 10.

0010 In addition, 25 is the liquid level warning light for reservoir tank 15, and 26 is the water temperature warning light for radiator 1. , 27 is a clogging warning light.

As shown in FIG. 2, the characteristics of the sensor 22 for the passing air volume P are such that no injection signal is output in the area above the characteristic line P _O with values preset based on the vehicle speed and fan rotation speed, and no injection signal is output in the area below. An injection signal shall be issued.

Next, the operation of this device will be explained with reference to FIG. Starting at step _Q1 , when the cooling water temperature T of the radiator 1 becomes equal to _or higher than the predetermined value TO, step _Q2 becomes Yes, and the control unit 16 operates the pump 14 and the switching valve 13 based on the signal _S1 of the water temperature detection sensor 20. , the injection nozzle 10 sends water to the radiator 1 and the condenser 2 to cool them. Further, even if the cooling water temperature T of the radiator 1 is below the predetermined value T _O and step Q ₂ is NO, if mud adheres to the radiator 1 or the condenser 2 and the passing air volume P becomes below the predetermined value P _O , step Q ₃ is executed. YES, the control unit 16 operates the pump 14 and the switching valve 13 based on the output signal _S3 of the sensor 22 of the passing air volume P, and the injection nozzle 10 sends water to the radiator 1 and the condenser 2 to remove the mud attached to them. Wash out.

[0013] The operation of the injection nozzle 10 as described above is shown in the table below.

[0014]

[Table 1]

[0015] Furthermore, in order to determine whether or not to inject water based on the vehicle speed V and fan rotation speed N, a three-dimensional map is as shown in FIG. FIG. 5 shows the automatic control flow of the sensors 23, 20, and 22. When the light amount sensor 23 detects a decrease in light amount, the injection nozzle 12 is activated by the signal _S4 to clean the headlamp 11, and When the water temperature detection sensor 20 detects a rise in water temperature, the injection nozzle 10 is activated by the signal _S1 to cool the radiator 1, and when the passing air volume sensor 22 detects mud clogging, the injection nozzle 10 is activated by the signal _S3 . The condenser 2 and the radiator 1 are cleaned, and the injection state at that time is confirmed by the signal _S5 of the detection sensor 24. As a result, the injection nozzle 10 is activated through the OR circuit 30 in response to the signals S ₁ and S ₃ from either the water temperature detection sensor 20 or the passing air volume sensor 22 .

[0016]

[Effect of the idea]

As described above, according to the present invention, the water temperature of the radiator or the radiator or air conditioner detects the degree of clogging of the sensor and injects water at high pressure into the radiator or condenser. This prevents these cores from clogging and overheating.
