Field of the Invention [0002]The present invention relates generally to a heat exchanger for a cooling system, which may be commonly used for a compact cooling equipment, in particular to a heat exchanger for a cooling system capable of providing a compact heat exchanging system having a compressor and a radiator by minimizing an occupied volume of the heat exchanger, which is capable of simplifying a piping structure by integrating a cooling medium injection pipe and a cooling medium exhaust pipe into a single piping structure, which is capable of preventing water leakage through a pipe connecting portion, and which is capable of improving a cooling performance of the cooling system having the heat exchanger and capable of highly enhancing a thermal efficiency per an electric heat area in the heat exchanger by disposing a spiral partition between a heat exchanging part, a heat exchanger pipe and a capillarity tube in a main body of the heat exchanger so as to guide a mixed flow of water and cooling medium in the creation of the vortex or swirling motion. In which a heat exchanging part and a passage for exhausting cooling water are disposed along the rod-shaped main body of the heat exchanger thereby resulting in the formation of a "U"-shaped channel.

In which an end of the pipe for exhausting cooling medium is inserted into the inlet of the heat exchanger pipe together with the capillarity tube. [0003]2. Description of the Related Art [0004]Conventionally, a variety of cooling equipments have been used for a fishing port for raising an aquarium fish at home or a fish preserve for storing a live fish or all sorts of marine products. The cooling equipments have a function of for maintaining the degree of freshness by maintaining a temperature of water regularly, which is filled in the fishing port or in the fishing preserve. The cooling equipment intended to accomplish this purpose comprises a cooling system of small scale in comparison with commercial or industrial equipments of large scale. [0005]A conventional heat exchanger 100 as shown in FIG. 1 has been used for the cooling equipment of small scale. A cooling water inlet 111 and a cooling water outlet 112 are connected to an upper side of the heat exchanger 100 having a box-shaped main body 110, respectively. A cooling medium inlet pipe 113, a cooling medium out pipe 114 and a sensor connecting pipe 116 are installed at a front side of the main body 110. A sensor 117 for measuring a temperature of water is inserted into the sensor connecting pipe 116 together with an electric wire 118. [0006]A heat exchanger pipe 115 is wounded in a spiral manner and then it is inserted into the main body 110. One end of the heat exchanger pipe 115 is connected with the cooling medium inlet pipe 113 and the other end of the heat exchanger pipe 115 is connected with the cooling medium out pipe 114. The cooling medium can flow through the heat exchanger pipe 115. Meanwhile, a certain space for storing cooling water is formed in the main body 110 to the outside of the heat exchanger pipe 115. A sensor tip of the sensor 117 protrudes toward said space so as to measure the temperature of water. [0007]As shown in FIG. 2, the conventional heat exchanger 100 as described above is inserted into a casing 210 of a heat exchanging system 200 together with a compressor 220 and a radiator 230 having a radiating fan 240. The cooling medium inlet pipe 113 and the cooling medium out pipe 114 are connected with the radiator 230 and the compressor 220, respectively. One hose 119 for introducing cooling water is connected with the cooling water inlet 111. Likewise, other hose 119 for exhausting cooling water is connected with the cooling water outlet 112. [0008]If a cooling medium flows through the heat exchanger pipe 115 in the main body 110 due to execution of cooling cycle with the aid of the compressor 220, the water introduced into the main body 110 from the cooling water inlet 111 is cooled at a predetermined temperature. Thereafter, the cooled water is exhausted through the cooling water outlet 112 to the outside of the heat exchanger 100. Consequently, cooling water can be supplied to the fishing port for raising an aquarium fish at home or the fish preserve for storing a live fish or all sorts of marine products. [0009]One drawback of using the conventional heat exchanger 100 is that the box-shaped main body 110 may require a relative large volume for installing it in the heat exchanger 100, thereby resulting in an increase of total dimensions of the casing 210. In other words, when the heat exchanger 100 is used as a constitutional element for the heat exchanging system 200 together with the compressor 220 and the radiator 230, then it is hard to provide a compact heat exchanging system that is required to be employed in a certain cooling equipment of small scale. [0010]Another drawback of this conventional heat exchanger 100 is that water introduced into the main body 110 through the cooling water inlet 111 slowly flows and is slow in heat exchange relationship with the heat exchanger pipe 115, and therefore the water presented at a certain position to the outside of the heat exchanger pipe 115 does not have to be subjected to a cooling operation. Unfortunately a surface of the heat exchanger pipe 115 does have to be subjected to a cooling operation. This inevitably causes a deterioration of the cooling performance provided by the heat exchanger 100 in the cooling system. [0011]On the basis of the above-mentioned consideration of the above point, a method for installing the heat exchanger pipe 115 by winding it up at several ten times along an interior of the main body 110 in a spiral manner so as to increase an electric heat area has recently been used. [0012]However, this inevitably causes a waste of stainless steel or titanium that is conventionally used as a basic material for producing the heat exchanger pipe 115. Furthermore, since the process for bending the heat exchanger pipe 115 in a spiral manner is relatively complicated, the volume to be occupied by the heat exchanger 100 is readily increased. Furthermore, a long time occurs to perform the process and thereby it has poor productivity. [0013]On the basis of the above-mentioned consideration of the heat exchanger 100's characteristics, it is required to obtain a complete waterproofing at a connecting portion of the pipes, such as the cooling water inlet 111, the cooling water outlet 112, the cooling medium inlet 113 and the cooling medium outlet 114, so as to use the heat exchanging system 200 with safe. [0014]Furthermore, on the basis of consideration of basic water leakage prevention, it is most preferable to minimize the size of the connecting portion of the pipes under the same waterproofing condition. [0015]Since the hose 119 made of a soft material is respectively connected with the cooling water inlet 111 and the cooling water outlet 112, then a work for sealing the connecting portion there between is simple. However, since the cooling medium inlet 113 and the cooling medium outlet 114 respectively comprise a metal pipe unlike the main body 110, then the work for sealing the connecting portion is troublesome. The leakage of cooling water in the heat exchanger 100 is mainly occurred at the connecting portion of the pipes. [0016]On the basis of the above-mentioned consideration of the above point, what is needed is an improved heat exchanger that basically solves the problem related to the cooling water leakage by minimizing the connecting portion of pipes for allowing cooling medium to flow there through, which is capable of providing an excellent cooling performance, which has a compact structure adapted to be employed in a cooling equipment of small scale, and which gives a considerable reduction in costs. SUMMARY OF THE INVENTION [0017]The present invention solves the foregoing problems. It is an object of the present invention to provide to a heat exchanger for a cooling system capable of providing a compact heat exchanging system having a compressor and a radiator by minimizing an occupied volume of the heat exchanger, which is capable of simplifying a piping structure by integrating a cooling medium injection pipe and a cooling medium exhaust pipe into a single piping structure, and which is capable of preventing water leakage through a pipe connecting portion. [0018]In which a heat exchanging part and a passage for exhausting cooling water are disposed along the rod-shaped main body of the heat exchanger thereby resulting in the formation of a "U"-shaped channel. In which the capillarity tube for injecting cooling medium is disposed in the heat exchanger pipe at a hollow, double-barreled tube type. In which an end of the pipe for exhausting cooling medium is inserted into the inlet of the heat exchanger pipe together with the capillarity tube. [0019]Furthermore, it is other object of the present invention to provide to a heat exchanger for a cooling system capable of improving a cooling performance of the cooling system having the heat exchanger and capable of highly enhancing a thermal efficiency per an electric heat area in the heat exchanger by disposing a spiral partition between a heat exchanging part, a heat exchanger pipe and a capillarity tube in a main body of the heat exchanger so as to guide a mixed flow of water and cooling medium in the creation of the vortex or swirling motion. [0020]In order to achieve these objects, the present invention provides a heat exchanger for a cooling system comprising a main body to which a cooling water inlet and a cooling water outlet are connected, in which a heat exchanging pipe for circulating a cooling medium is inserted into the main body, which cools water introduced through the cooling water inlet pipe, characterized in that: the main body is constituted of a heat exchanging part for performing a cooling operation by virtue of a heat exchanging pipe and an exhausting passage, wherein the heat exchanging part and the exhausting passage are integrally formed with each other such that they can create a U-shape channel and thereby a certain space is created therein, wherein the cooling water inlet is connected with a one side of an upper end of the main body, which is corresponding to a one end of the heat exchanging part, wherein the cooling water outlet is connected with the other side of the upper end of the main body, which is corresponding to a one end of the exhausting passage, wherein a connecting tube is integrally connected and installed to a front side of the upper end of the main body at a position adjacent to the cooling water inlet, wherein the heat exchanger pipe passes through the connecting tube and continuously it is inserted in the heat exchanging part of the main body, wherein a capillarity tube for injecting cooling medium and a cooling medium exhausting pipe are inserted into the heat exchanging pipe and then held by virtue of a packing.

Furthermore, a spiral partition for circulating cooling medium in the creation of the vortex or swirling motion, which is introduced from the capillarity tube to the cooling medium exhausting pipe, is installed between an inner side surface of the heat exchanging pipe and an outer side surface of the capillarity tube.
