FIELD OF THE INVENTION [0001] The present invention relates to a cooling device. More particularly, the present invention relates to a recurring cooling device making use of natural water. BACKGROUND OF THE INVENTION [0002] With development of the current industry, thermal exchangers have been widely employed in the oil-refining industry, petrifaction industry, hi-tech electronic industry and the like, as the devices for heat removing. [0003] Since the thermal exchanger is generally used in miscellaneous environments where the conditions of capacity, pressure, temperature and the like are different from one another, the thermal exchanger has to be formed in various shapes, structures and categorizations. The shell-tube thermal exchanger can be one of the most widely used thermal exchangers. Such shell-tube thermal exchanger can be seen from FIG. 1. As shown, a cool liquid serves as a coolant 14 and flows into an enclosed trough body 11 having the thermal exchanger formed therein, the thermal exchanger being formed by winding a lot of slender metal tubes 12 and the thermal exchanger being surrounded by the coolant. The enclosed trough body 11 is termed as "casing", while the metal tube is termed as "tube body". [0004] The shell-tube thermal exchanger is operated according to the process described below. At first, a thermal fluid 16 to be cooled is poured into the thermal exchanger composed of the metal tubes 12. Then, the heat of the thermal fluid 16 is transferred to the coolant 14 whose temperature is relatively lower than that of the thermal fluid 16. As such, a thermal exchange occurs between the thermal fluid 16 and the coolant 14. In the course of thermal exchanging, the thermal fluid 16 is lowered in temperature and becomes another thermal fluid 17, while the coolant 14 is elevated in temperature and becomes another coolant 15. As such, the cooling function is achieved. [0005] The metal tubes 12 are typically extended and fixed by welding to a tube plate 13 to form a tube group. Next, the tube group is inserted into the casing 11 to from the thermal exchanger. In the thermal exchanger, the metal tubes 12 are disposed horizontally in general. However, the metal tubes 12 may also be disposed vertically in the case that the area occupied by the metal tube is limited or the thermal exchanger is used for the purpose of distillation. [0006] The thermal exchanger may be categorized into several types according to the connection between the tube plate and the casing, such as a fixed tube plate based thermal exchanger, a floated head based thermal exchanger and a U-shape tube based thermal exchanger. However, no matter which type of the thermal exchanger is used, there exist the following issues. Firstly, Since the casing is sealed up and thus deposited articles therein are hard to be removed, a highly polluted or erosive fluid is not suitable to serve as the coolant. Secondly, there is a temperature difference between the two fluids, at the casing side and the metal tube side, which is greater than 100.degree. C. In addition, an excessively large difference of thermal expansion coefficient is presented between the material of the casing and that of the metal tube. Accordingly, a significant expansion difference occurs between the casing and the metal tube and causes a non-uniform expansion in the thermal exchanger, leading to failure of the thermal exchanger. This is also true for the case where the temperature is low owing to the significant difference of thermal expansion coefficient. Thirdly, for the thermal exchanger, the more complicate the structure thereof is, the higher the cost therefor will be. Fourthly, the larger the pressure in the thermal exchanger is or the higher the requirement of the thermal exchange is, the thicker the metal tube will be and the larger the volume of the thermal exchanger will be, leading to a larger occupation area of the thermal exchanger. Fifthly, the thermal exchanger generates waste heat in operation into the ambient environment, adversely increasing the greenhouse effect and polluting the environment. Sixthly, the thermal exchanger generates unpleasant noises in operation. Seventhly, fluorine and chlorine carbides generally serve as the coolant, forming a menace to the ozone layer surrounding the earth. Eighthly, a huge amount of power energy is consumed during the temperature reduction process, causing a power waste for the heat exchanger. [0007] Take the air-conditioning apparatus for example, the waste heat vented therefrom will be dispersed in the air, which causes a power thermal saturation of the air nearby not long after the operation of the air-conditioning apparatus, and thus the waste heat is accumulated and needs a long time to be removed. Consequently, the air temperature is elevated and the operating efficiency of the heat exchanger is lowered. [0008] From the above description, it is known that how to develop a recurring natural water cooling device has become a major problem to be solved. In order to overcome the drawbacks in the prior art, a recurring natural water cooling device is provided. The particular design in the present invention not only solves the problems described above, but also is easy to be implemented. Thus, the invention has the utility for the industry.
