Description
A LIQUID COOLING SYSTEM
Field of the Invention
The present invention relates to a general purpose cold water and cold air generator assembly. Background of the Invention
The vortex tubes are mechanical devices which only operate with pressurized gas, and do not have any moving parts except control valve. This mechanical device separates high pressurized gas flow entering tangentially into the tube into two low pressure currents one of which is hotter than the inlet gas, and the other is colder than the inlet gas.
In embodiments wherein the vortex tubes are used with vortex method, a significant amount of energy is lost by releasing large part of the air which is cooled to the environment. Cold water generators with closed pressurized system operating with vortex method and using pressurized air have inefficient method of reusing the air which is higher than atmospheric pressure as a result of expansion. Furthermore, noise level is high in cooling systems using vortex method. The other cold water generators known in the state of the art have complex structures, and also have high volume and weight values. Furthermore, expensive fluids and expensive system equipment are required for studies under -20 °C, and expensive and complex components are required for realizing heating function.

United States Patent Document noUS3074243, an application known in the state of the art, discloses a water cooling device using a vortex tube. The said system is comprised of a water tank and air pipes surrounding the tank, and the air cooled in the vortex tube is ppased through the said pipes, ad thus the water inside the tank is enabled to be cooled.
United States Patent Document US3144754, an application known in the state of the art, discloses a water cooling device using a vortex tube. The said system comprises a water tank, and pipes in form of coil provided inside the tank and through which the cooled air passes. The air cooled in the vortex tube is passed through the said pipes, and thus the water inside the tank is enabled to be cooled.
Summary of the Invention
The objective of the present invention is to provide a liquid cooling system which enables more economical cold water generation relative to similar systems with pressurized air. By means of the inventive cooling system, it is easily reached to temperatures under -20°C. The limit condition in this system is the condensation temperature of the gases within the air (oxygen-carbon dioxide). In the inventive liquid cooling system, air in temperature close to the atmosphere temperature is sent outside the system, all of the thermal energy gained with expansion of pressurized air is used, and thus the cooling coefficient is higher than the similar methods known in the technique.
Furthermore in the inventive liquid cooling system, noise level is significantly decreased, and this system is much lighter than the present systems and takes less space. Detailed Description of the Invention

An inventive liquid cooling system (1) essentially comprises
at least one tank (2) which has liquid (L) therein,
at least one pressurized air inlet (3) which is outside the tank (2) and enables the pressurized air to enter in,
at least one inner cooling pipe (4) which is inside the tank (2) and enables the air entering through the pressurized air inlet (3) to be cooled by the liquid (L) inside the tank,
at least one vortex generator (5) which enables the air coming out of the inner cooling pipe (4) to go out as warm air from a warm air outlet (5.1) and to go out as cold air from a cold air outlet (5.2),
at least one air pressure booster (6) which is driven by the air coming out of the warm air outlet (5.1),
at least one pump (7) which enables the liquid (L) which is heated to be transferred into the tank (2) again after the liquid (L) cooled inside the tank (2) is used in a medium (M). In the inventive liquid cooling system (1), first the pressurized air received from an installation enters into a tank (2) which is being cooled and has a liquid (L) therein through a pressurized air inlet (3). The said air passes through an inner cooling pipe (4) present inside the tank (2), and the temperature of this air decreased a little.
In one embodiment of the invention, the inner cooling pipe (4) starts from the base of the tank (2) and extends spirally along the upper part. In this way, the air passing through the inner cooling pipe (4) can be cooled more since it is subjected to the liquid (L) inside the tank (2) more.
The inner cooling pipe (4) is connected to the vortex generator (5) via a pipe. The air going out of the inner cooling pipe (4) enters into a vortex generator (5).. Pressurized air current coming to the vortex generator (5) the temperature of which is decreased a little is separated into two low pressure currents. One of these air currents goes out of the warm air outlet (5.1) such that it will be warmer than the air entering into the vortex generator (5), and the other goes out of the
cold air outlet (5.2) such that it will be colder. The said warmth and coldness calibration can be made by means of a heating/cooling calibration valve (5.3) provided on the vortex generator (5). Warm air outlet (5.1) of the vortex generator (5) drives an air pressure booster (6). Therefore, temperature is converted into useful energy by means of this cooling system (1).
Cold air the temperature of which is decreased below inlet temperature after it is expanded on the vortex generator (5) is again given into the liquid (L) inside the tank (2) again via a pipe with douching method. In this way, cold air going out of the liquid (L) as bubble cools the liquid (L) inside the tank (2), and the noise is reduced. The air going out of the liquid (L) in the tank (2) as bubble is pressurized by the air pressure booster (6), and it is included into the air entering through the pressurized air inlet (3) of the tank (2). In this way, since the air added to the circulation air by the air pressure booster (6) is cold, the circulation air cools, and the energy amount required to compress this air decreases as it cools down.
After the liquid (L) cooled inside the tank (2) is used in a medium (M), the cool liquid (L) is heated and the heated liquid (L) is again transferred into the tank again via a pump (7).
