[16] The kimchi storage, at least one kimchi storage room 24 is provided in the interior of the main body 22 having a predetermined appearance, the upper surface of the main body 22 to enter the upper side to open and close the door ( 23) is hinged to the upper back of the main body. The front portion of the main body 22 is provided with a control unit 25 is provided with a plurality of buttons that can be controlled to refrigerated or mature kimchi stored in the kimchi storage room 24.
[17] Figure 2 is a longitudinal sectional view showing the internal structure of a conventional kimchi storage. As shown in the figure, an inner lower portion of the main body 22 is formed with a device chamber 26 which is partitioned from the kimchi storage chamber 24. The device chamber 26 is driven by an applied power source and is a refrigerant having a low temperature and low pressure. Compressor 31 is provided to compress the refrigerant into a high-temperature, high-pressure refrigerant, the condenser 32 to condense the refrigerant passing through the compressor 31, and the operation unit for controlling the drive of the compressor (31) As well as being connected to the (25) is provided with a control unit 40 for setting the temperature of the kimchi storage room 24 to the appropriate temperature.

[19] On the other hand, on the outer circumferential surface of the kimchi storage chamber 24 to absorb and cool the heat in the kimchi storage chamber 24 while evaporating the refrigerant under reduced pressure at a low temperature while passing through the condenser 32 and the capillary tube 33. The provided evaporator 34 is installed so as to wrap up the outer circumferential surface of the kimchi storage room 24 at a predetermined interval from the lower side to the upper side, and FIG. 3 is a perspective view illustrating an evaporator installation structure of a conventional general kimchi storage room.
[20] However, in the conventional kimchi reservoir made as described above, since the refrigerant tube forming the evaporator 34 has a circular shape and the contact surface for heat transfer is small, the heat transfer rate is lowered, and the diameter of the refrigerant tube forming the evaporator 34 is reduced. Although the space of the kimchi storage room 24 had to be secured to the maximum, the space utilization of the kimchi storage room could not be increased because the evaporator 34 was manufactured and used with copper having a diameter of 5 mm to 7 mm.
[21] In addition, by using a mixture of iron, copper, and aluminum as the materials of the evaporator 34 and the condenser 32, it is difficult to assemble and produce work, such as welding work, waste of material during disassembly is severe and excessive disassembly cost. There was an issue going into.

[23] In the present invention for achieving the above object, in the kimchi storage in which the refrigerant pipe is arranged to achieve a cooling system through the circulation of the refrigerant between the compressor, the condenser and the capillary tube installed in the equipment room and the evaporator surrounding the outer circumferential surface of the kimchi storage chamber. The evaporator is installed to surround the outer circumferential surface of the kimchi storage chamber with a micro-flow lead pipe, and the micro-flow path comprises an adapter for connecting both ends of the evaporator made of the micro-flow lead pipe with the compressor inlet and the capillary outlet, respectively. Provides an evaporator installation structure for kimchi storage using flat pipes.

[25] Hereinafter, with reference to the accompanying Figures 4, 5 and 6 will be described in detail with respect to the evaporator installation structure of the kimchi storage using the micro-flow lead pipe of the present invention, the same name and the same reference numerals are assigned to the same parts as the conventional structure. The detailed description is omitted.
[26] And, throughout this specification and claims, “aluminum” is intended to include both pure aluminum and aluminum alloys.
[27] As shown, the kimchi storage using the micro-flow lead pipe of the present invention has a control unit 40 in a state in which a basic refrigeration cycle of the compressor 31, the condenser 32, the capillary tube 33, and the evaporator 34 is provided. , Kimchi storage room (24).
[28] Here, the gist of the present invention is that instead of configuring the refrigerant tube forming the evaporator 34 of the kimchi reservoir as the conventional circular refrigerant tube of copper material having a diameter of 5 mm to 7 mm, it is made of a fine flow path made of aluminum. The evaporator 34 is installed by using the tube 90, and the adapter 95 for connecting the micro flow path storage tube 90, the condenser 33, and the compressor 31 is provided to perform a refrigeration cycle of the kimchi storage. It is made up.
[29] The micro-flow path tube 90 is provided with a predetermined distance from each other while extending in the longitudinal direction in a state spanning the flat upper and lower walls (91, 92) and the upper wall (91) and the lower wall (92). Two reinforcement walls 93 and a plurality of communication holes 94 partitioned by the reinforcement walls 93 to form passages of the refrigerant.
[30] At this time, the height of the fine flow path tube 90 is preferably in the range of 0.8 to 4.0 mm, particularly in the range of 1.4 to 3.5 mm. If the pipe height is less than 0.8 mm, the refrigerant passage is lowered, resulting in a pressure loss of the refrigerant. If the tube height is more than 4.0 mm, not only is it difficult to miniaturize, but the heat exchange efficiency is deteriorated.
[31] The reinforcing wall 93 preferably has a pitch of 0.5 to 3.0 mm, particularly 1.0 to 2.5 mm, in the width direction of the tube. If the pitch of the reinforcing wall 93 is less than 0.5 mm, the refrigerant passage is narrowed, so that a pressure loss of the refrigerant occurs, and if it exceeds 3.0 mm, the heat exchange efficiency is deteriorated.
[32] The height of the reinforcing wall 93 is preferably in the range of 0.5 to 3.5 mm, particularly in the range of 0.8 to 3.0 mm, for the same reason as the tube height.
[33] The cross-sectional area of the communication hole 94 is preferably in the range of 3.0 to 6.0 mm 2, particularly in the range of 3.5 to 5.5 mm 2. When the cross-sectional area of the communication hole 94 is less than 3.0 mm 2, not only the exchange of the refrigerant is sufficiently performed, but also the communication hole 94 is blocked by heat flowing when lead is produced by soldering a fine flow path tube with lead after rolling. There exists a concern, and when it exceeds 6.0 mm <2>, the pressure resistance of the communication hole 94 will worsen.
[34] In conclusion, the micro-flow lead pipe 90 is preferably formed to be as low as possible in relation to the improvement and miniaturization of the heat exchange efficiency.
[35] At this time, in the selection of the processing method should be produced in consideration of the internal pressure acting on the communication hole 94, it is also possible to manufacture through extrusion in addition to the method of contacting the solder after the upper and lower parts by rolling, respectively.
[36] In addition, one side of the adapter 95 is fitted with the inlet of the circular compressor 31 or the outlet of the capillary tube 33, and the other side of the adapter 95 is fitted with the fine flow path tube 90 forming both ends of the evaporator 34. .
[37] Of course, in the present invention, both the inlet and the outlet of the evaporator 34 leads to the equipment room 26 provided below the kimchi storage room, and the outlet part is connected to the compressor 31 arranged in the equipment room 26.
[38] Hereinafter, the operation and effects of the present invention will be described in detail.
[39] According to the refrigerant pipe structure according to the present invention as described above, the outlet of the capillary tube (33) is connected through the adapter 95 and the inlet of the evaporator (34) consisting of the fine flow path tube 90, the outlet of the evaporator (34) Are interconnected via the compressor 31 inlet and adapter 95.
[40] In this configuration, the low-temperature and low-pressure refrigerant flows through the condenser 32 disposed in the equipment chamber 26 through the capillary tube 33 and passes through the adapter 95 to the plurality of communication holes 94, respectively. In this process, the contact area of the micro-flow lead pipe becomes wider than that of the conventional circular refrigerant pipe, so that the heat transfer rate is improved.
[41] Thereafter, the refrigerant is heat-exchanged with the interior of the kimchi storage chamber to vaporize, and then the refrigerant is combined into one stem again from the adapter 95 at the outlet of the evaporator 34 to enter the compressor 31.
[42] According to the refrigerant piping configuration of the kimchi storage using the micro-channel lead pipe according to the present invention as described above, the micro-channel having a plurality of communication holes divided into aluminum reinforcement wall of the evaporator of the conventional kimchi storage made of copper It is made of flat pipes so that the refrigerant passes through smaller diameter distribution pipes independently and in parallel, while maintaining the same refrigeration system while making the installation space smaller and increasing the space utilization of the product. It is a very useful and effective invention that facilitates processing and prevents waste of materials during disposal.
