Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling device for a radiator in a car cooler.

As is well known, an automobile cooling system (car cooler) is equipped with a driving engine as its power source, and its radiator, which is called a radiator, is generally arranged in a space on the front side of the radiator of the automobile engine.

The cooling effect of the cooler is significantly influenced by the quality of the heat radiation effect of the radiator, and the desired cooling effect can only be obtained if the heat radiation effect is performed smoothly.

However, car coolers are only used during the summer when the temperature is high, and the engine heat is added to the high temperatures, so the cooler radiator is constantly exposed to adverse conditions during use.

In particular, conditions worsen during traffic jams, and as the engine overheats, the heat dissipation of the cooler radiator becomes extremely uneven, resulting in a significant drop in cooling performance, causing discomfort not only to the driver but also to passengers in the case of taxis. will give.

In particular, as described above, when a cooler radiator is exposed to extremely bad conditions and a significant drop in heat dissipation is expected due to this, water is sprayed onto the surface of the radiator to immediately recover the heat dissipation and cool the air conditioner. To provide a radiator cooling device that can prevent a decrease in effectiveness, a water sprinkling pipe 3 having a large number of pores 2 is disposed on the front surface of a cooler radiator 1 so as to be swingable in angle. 3 into the water supply pump 5 in the water supply tank 4
The radiator 1 is connected to the radiator 1 via a hose 6, and the sprinkler pipe 3 is swung when desired to spray water onto the front surface of the radiator 1.

To explain more specifically, in FIG.
, engine radiator 21, and fan propeller 2
The engine 20 is installed in the engine section of an automobile equipped with a second engine.
A compressor 7 operated from a shaft 23 is installed, a radiator 1 is arranged in the space in front of the engine radiator 21, and a cooler main body 8 is installed between the engine section and the inside of the automobile, and these are connected by a circulation pipe 9. In this car cooler device, the refrigerant is compressed and liquefied → expanded and vaporized to send cold air into the car interior.In the front of the cooler radiator 1, a large number of pores 2 are fixed to a holder 10.
A water sprinkling pipe 3 having a holder 10 is pivotally connected to a fixed shaft 11, and an end portion 12 of the water sprinkling pipe 3 is communicated with a compressed water pump 5 of a water supply tank 4 via a hose 6. When desired, the water sprinkler pipe 3 is angularly swung in front of the radiator 1 to dissipate water onto the front of the radiator 1 to cool the radiator 1 which is in a high temperature state. It is designed to remove heat from the surface and achieve an effective cooling effect with a small amount of water.

Regarding the above-mentioned swinging means for the sprinkler pipe 3, for example,
As shown in Figures 2 to 4, the holder 1 of the watering pipe 3
A long hole 13 is provided in the lower part of the pivot portion of the motor 14, and a worm 15 and a worm wheel 16 are inserted into the long hole 13.
The eccentric pin shaft 18 of the crank disk 17 that rotates through a speed reduction mechanism is fitted, and the water sprinkling pipe 3 is controlled by controlling the motor 14 by turning on and off a switch (not shown) installed inside the vehicle. Alternatively, as shown in FIG. 5, a crank 25 may be attached to a low-speed motor 24, and the lower end of the holder 10 may be connected to the crank 25 by a rod 26. The rotating motion of the rod 26 may be converted into a reciprocating motion of the rod 26 to swing the holder 10 in an angle, thereby swinging the sprinkler pipe 3.

In any case, the means for swinging the sprinkler pipe 3 is determined as appropriate in relation to the installation position of the cooler radiator 1 in the engine section of the automobile and the available space.

Further, the water in the water supply tank 4 is replenished from time to time, but if the drain water of the cooler 8 is led to the water supply tank 4, the water replenishment period can be greatly extended, which is convenient. Furthermore, it is more effective to mix a cooling accelerator into the water.

It is more preferable that the pores 2 of the water pipe 3 are so small that the water sent by the pressurizing action of the water pump 5 is ejected in the form of mist rather than in the form of a shower. The water pump 5 is preferably wired so that it is turned on and off in synchronization with the swinging motor 14 of the sprinkler pipe 3 described above.

In this way, the present invention erects the water sprinkling pipe 3 having a large number of pores 2 on the front surface of the cooler radiator 1 so as to be able to swing at an angle, and connects the end of the water sprinkling pipe 3 to the water supply pump in the water tank 4. 5 through a hose 6, and when desired, the sprinkler pipe 3 can be swung in front of the radiator 1 to spray water onto the surface of the radiator 1. Therefore, when using the cooler in summer, , When the cooling power of the cooler 8 has decreased or is expected to decrease due to factors such as when the temperature is high and the heat dissipation effect of the radiator 1 is reduced, or when the heat dissipation effect is not sufficient due to traffic congestion, etc., the switch ( (not shown), activates the water supply pump 5 and drives the motor 14, swinging the watering pipe 3 from side to side and opening its pores 2.
Water can be sprayed toward the surface of the radiator 1, and this spraying of water rapidly promotes heat dissipation on the surface of the radiator 1, and even in the worst case, this watering operation can be repeated several times every 2 to 3 minutes. If done, radiator 1
The heat is radiated sufficiently, the overheating phenomenon is eliminated, and the deterioration of the cooling function can be completely prevented.

Moreover, in the present invention, since water is sprayed onto the surface of the radiator 1 by angular swinging of the water sprinkler pipe 3 having a large number of pores 2, the maximum effect can be obtained with a small amount of water.

Furthermore, since it can be installed in a narrow space, it is suitable for use as a radiator when a cooler is added to a car that is not originally equipped with a cooler. It is possible to completely prevent overheating of the engine and cooler radiator and the resulting deterioration of the cooling function.
