BRIEF SUMMARY
DESCRIPTION
The present invention relates to a system for the refrigeration of liquids and/or gases, utilizing permanent elements arranged in one group.
The system comprises the utilization of a cluster of tubes made of high thermal conductibility materials, where in the central or internal tube a gas or liquid is made to pass at low temperature and in the tubes around its periphery the gases or liquids it is desired to refrigerate pass. The tubes may be maintained in contact by an external joining tube made of plastic or rubber, which, besides exerting pressure to join the tubes together, helps to insulate the group in tubes, and creates a gaseous refrigerated atmosphere, which acts as an additional area for heat exchange in the peripheral tubes. Considering that once there is sufficient power of refrigeration in the internal tube, the heat exchange will be greater however much greater is the total difference of lengths between the internal tube and the external tubes, the external tubes may be wound around the internal tube which serves as axis, thus gaining up to 20% of length in relationship to the linear placing of the tubes. The capacity of the system shall be preset and is dependent upon its total length, as well as the difference in diameter between the internal refrigeration tube and the external refrigerated tubes, it being that however smaller (in diameter) the external tubes are in relationship to the internal tube, the greater shall be the heat exchange.
The system under consideration is extremely safe since there are always two tubular walls separating the refrigerating liquid and/or gas of the liquids and/or gases to be refrigerated, yet enabling the refrigeration of as many liquids and/or gases as are the number of the external refrigerated tubes or only one liquid or gas utilizing appropriate connections to join the whole refrigerated tube network to the liquid and/or gas tubing in question. The tube cluster thus obtained is easy to thermally insulate and may be maintained stretched as well as curved for easy installation when required by the particular project, thus obtaining an easily manufactured machine, with low cost, maximum safety and high performance in relationship to the present refrigeration coils.
In the accompanying drawings a preferred embodiment is illustrated wherein;
FIG. 1 shows a transverse section showing the central refrigeration tube (1), the peripheral heat exchanger tubes (2), the auxiliary gas atmosphere for heat exchanging (3), and the external joining and insulating tube (4).
FIG. 2 shows a transverse section of the system, wherein the central refrigeration tube (1), is surrounded by a greater number of peripheral heat exchanger tubes of smaller diameter (2), the auxiliary gas atmosphere for heat exchanging (3) and the external joining and insulating tube (4).
FIG. 3 shows the peripheral heat exchanging tubes (2) wound around the internal refrigeration tube (1).
FIG. 4 shows a general view of the group showing the internal refrigeration tube (1), the peripheral heat exchanging tubes (2), linked to the multitubular connections (5), and the external joining and insulating tube (4).
1. Heat exchange system comprising a central internal tube through which a refrigerating medium passes, periphery of said central internal tube, each and every heat exchanger tube in surface to surface contact with the periphery of said central internal tube through which the medium to be refrigerated passes, two adjacent ones of said heat exchanger tubes as well as in surface to surface contact with the periphery of said central internal tube and exchanger tubes and maintaining them in contact with each other and in contact with said central internal tube thereby creating a cold chamber enclosing all of said tubes.
2. A heat exchange system according to claim 1 wherein, said external heat exchanger tubes each contain the same medium to be cooled.
3. A heat exchange system according to claim 1 wherein, each said external heat exchanger tube contains a different medium to be cooled.
4. A
