Description

Evaporator for refrigerator with device of ultrasonic waves

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an evaporator, which is one of means for constructing a refrigerator, which absorbs heat from the surroundings and rapidly lowers the ambient temperature when the liquid evaporates to become a gas. The evaporator is a liquid refrigerant expanded by an expansion valve. Is a type of heat exchanger that cools other fluids such as water by evaporating heat from the surroundings, and the refrigerant is cooled by rapid evaporation force due to increased scattering of refrigerant particles by a separate ultrasonic oscillator formed on one side of the refrigerant transport pipe. The present invention relates to an evaporator for a refrigerator having an ultrasonic oscillator for expanding and increasing refrigerant scattering, characterized in that the efficiency is improved.

In general, the inside of a refrigerator such as a refrigerator is cool because it uses the principle of heat of vaporization.

The heat of vaporization, as shown in Patent Application No. 10-2001-0044105, is a liquid that turns into a gas, absorbs heat from the surroundings and lowers the ambient temperature. When we apply alcohol to the back of the hand, the alcohol vaporizes the heat. It is the same principle that it absorbs and feels cool around the back of the hand.

That is, the low pressure and low temperature liquid refrigerant exiting the expansion valve in the action of the internal organs of the refrigerator circulated in the order of condenser, expansion valve, evaporator, compressor, and condenser absorbs heat from the surroundings and absorbs heat from the surroundings. It becomes a gas refrigerant, and since the vaporization occurs due to the absorbed heat, the temperature inside the refrigerator suddenly decreases, thereby keeping the inside of the refrigerator cool.

At this time, the cold air is spread throughout the freezer by the natural convection method in the case of a small freezer, the big freezer is spread throughout the freezer in a forced circulation method.

In other words, the compressor is called a compressor, and the air conditioner is located in the outdoor unit, and the refrigerant is compressed and sent to the condenser in a high pressure, a high temperature, and a small volume.

After that, the condenser cools the high-pressure and high-temperature compressed refrigerant to a low temperature. In the air conditioner, the outdoor unit rotates the fan to condense. In the refrigerator, the copper pipe behind the refrigerator and the cooling tower running on the roof of the building condense. It is formed to.

Thereafter, the expansion valve is a device that greatly expands the volume of the refrigerant passing through the condenser, and is formed so that the refrigerant temperature is very low. This is usually called an expansion valve, but in a small air conditioner or refrigerator, it is called a copper pipe capillary or an octopus tube.

Afterwards, the evaporator corresponds to a cold coil of an indoor unit cold coil of a air conditioner or a high cold plate of a refrigerator. It will play a role.

However, in the configuration of the refrigerator, conventionally, the refrigerant (water) to be circulated in the evaporator simply consists of a circulating structure, and there is a demand for a separate device and a consumer for improving the cooling efficiency.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the technical gist of the present invention relates to an evaporator which absorbs heat from the surroundings and rapidly lowers the surrounding temperature when the liquid evaporates and becomes a gas. The evaporator is a kind of heat exchanger that cools another fluid such as water by evaporating a liquid refrigerant expanded by an expansion valve to take evaporative heat from the surroundings, and the refrigerant is formed by a separate ultrasonic oscillator formed at one side of the refrigerant delivery pipe. It is an object of the present invention to provide an evaporator for a refrigerator having an ultrasonic oscillation device for expanding and increasing the refrigerant scattering, characterized in that the cooling efficiency is improved due to the rapid scattering of the refrigerant particles to improve the cooling efficiency.

In order to achieve this object, the evaporator of the present invention is formed on each side of the tank 110 in which the space G is formed, the refrigerant transport pipe 120 for circulating the refrigerant from the compressor and the expansion valve, respectively, The other side of the tank 110, the water evaporator body 100 is formed with a water circulation pipe 130 so as to promote evaporation by heat exchange with the refrigerant while the water circulates; Ultrasonic vibrator 210 is formed on one side or the other side of the refrigerant transport pipe 120 of the evaporator body 100 to oscillate ultrasonic waves in a circulating refrigerant to more finely disperse the refrigerant particles scattered more quickly to improve cooling efficiency by rapid evaporation. Ultrasonic oscillator 200 is provided; .

In this case, the ultrasonic oscillator 200 is coupled to the outer peripheral surface of the refrigerant transport pipe 120, the outer peripheral surface side end coupled to the diaphragm 220 including the ultrasonic vibrator 210, the diaphragm 220 is transferred to the refrigerant It is preferable to oscillate ultrasonic waves in the refrigerant circulating fixed inside the tube 120.

In addition, the ultrasonic oscillator 200 has a pipe tubular diaphragm 220-1 having a smaller diameter than the refrigerant conveying pipe 120 is formed, the oscillator 210 which is fixedly coupled to the outside after being introduced into the refrigerant conveying pipe 120. It is preferable to allow the ultrasonic wave to oscillate with respect to the refrigerant in the refrigerant transport pipe (120).

As such, the present invention relates to an evaporator that absorbs heat from the surroundings and rapidly lowers the ambient temperature when the liquid evaporates and becomes a gas. The evaporator evaporates the liquid refrigerant expanded by the expansion valve to heat the evaporation around. Is a kind of heat exchanger that cools other fluids such as water, and the refrigerant has an effect of improving cooling efficiency due to rapid evaporation force by increasing the scattering of refrigerant particles by a separate ultrasonic oscillator formed on one side of the refrigerant transport pipe.
