Description

Technical Field

[0001] The present invention relates to a cooling device that can instantaneously cool coolant water that requires cooling, such as a water purifier, a cold and hot water dispenser, a refrigerator, etc., to produce cold water.

Background Art

[0002] In water purifiers, cold and hot water dispensers, etc., in order to cool the normal temperature water that is raw water, a cold water tank is used to cool the water stored in the cold water tank and store it, and then the cold water stored in the cold water tank can be discharged to the outside by a cold water discharge operation.

[0003] When cooling the coolant water stored inside using such a cold water tank, in order to prevent the water stored inside the cold water tank from being contaminated, electrical energy is consumed for cooling even when cold water is not discharged. Also, when the water stored in the cold water tank is used up, it takes time to make cold water again.

[0004] Therefore, the demand for a technology that can instantaneously cool and discharge normal temperature water, which is coolant water, is increasing. The present inventor presented a device capable of instantaneous cooling in Korean Patent Registration No. 10-1804385.

[0005] The present inventor proposes another method of instantaneously cooling coolant water to produce cold water.

[0031] Figure 1 is a diagram showing the external appearance of a cooling device according to one embodiment of the present disclosure. Figure 2 is a diagram showing a longitudinal cross-section of a cooling device according to one embodiment of the present disclosure.

[0032] A cooling device according to one embodiment of the present disclosure is a cooling device for instantaneous cooling of water. As shown in Figures 1 and 2, the cooling device according to one embodiment of the present disclosure includes a housing 10. The housing 10 has an inlet 11 on its first end and a drain port 12 on its second end. A refrigerant circulation pipe 20 is provided on the outer surface of the housing 10. The refrigerant circulation pipe 20 is provided so as to spirally surround the outer surface of the housing 10. The water to be cooled flows into the inlet 11. The drain port 12 can discharge the cooled cold water. At this time, the water to be cooled is cooled by the cold air cooled by the refrigerant circulation pipe 20.

[0033] It should be noted that the components shown in Figures 1 and 2 are not essential, and cooling devices with more or fewer components can certainly be realized.

[0034] The following describes each component.

[0035] The housing 10 forms the external appearance of the cooling device. An inlet pipe 110 having an inlet 11 is inserted into the first end of the housing 10. The second end of the housing 10 has a drain port 12 through which the cooled water, which has been cooled by the water that flows in through the inlet 11, is discharged.

[0036] The drain port 12 is provided on the second end side of the housing 10. The drain port 12 can form a flow path through which the chilled water formed inside the housing 10 is discharged. The drain port 12 may be provided in the same direction as the inlet 11, depending on the number of pipes provided inside the housing 10. In the cooling device according to this disclosure, the positions of the inlet 11 and the drain port 12 are not particularly limited.

[0037] The water inlet pipe 110 has a tubular shape with openings formed at both ends in the longitudinal direction. The water inlet pipe 110 has an inlet 11 formed at its first end into which the water to be cooled flows. The inlet 11 may be provided outside the housing 10, but the cooling device according to this disclosure does not particularly limit the position of the inlet 11.

[0038] The second end of the water inlet pipe 110, which is inserted into the first end of the housing 10, may be located inside the housing 10. A first opening 111 may be formed at the second end of the water inlet pipe 110, i.e., the end on the drain port 12 side. With this configuration, the water to be cooled that flows in through the inlet 11 flows along the water inlet pipe 110 and is then discharged from the first opening 111.

[0039] A cooling pipe 120 with one end closed may be provided at the second end of the water inlet pipe 110. The cooling pipe 120 may be provided such that the closed end of the cooling pipe 120 covers the second end of the water inlet pipe 110 at a distance.

[0040] The tubular cooling pipe 120 may be provided inside the housing 10. The water inlet pipe 110 may be provided so as to be inserted longitudinally into the cooling pipe 120. The cooling pipe 120 with one end closed may be provided so that the closed end covers the first opening 111 of the water inlet pipe 110.

[0041] In one embodiment of the present disclosure, as shown in Figure 7, the cooling pipe 120, which has one end closed, may be configured such that a separate cover member 50 is attached to one of the open ends.

[0042] A cover member 50 according to one embodiment of the present disclosure can selectively close or open at least one end of a plurality of concentrically arranged pipes by covering and connecting it to at least one end of the plurality of pipes.

[0043] Specifically, the cover portion 50 has a circular or square shape corresponding to the cross-section of the pipe. Multiple grooves 51 are formed on one surface of the cover member 50, which can connect multiple pipes. The cooling pipe 120 and the second inner pipe 125 are fully fitted into some of the multiple grooves 51. This allows the cooling pipe 120 and the second inner pipe 125 to form a closed second end.

[0044] An inlet pipe 110 or a first inner pipe 115 is fitted into one of the other grooves 51. If at least a portion of the edge of the groove 51 into which the inlet pipe 110 or the first inner pipe 115 is fitted is deeper than the other portion, a first opening 111 or a second opening 115a can be formed as a flow path through which fluid can flow.

[0045] As a result, as shown in Figure 3, the water to be cooled that flows in through the inlet 11 at one end of the inlet pipe 110 flows along the inlet pipe 110 and is discharged from the first opening 111 at the other end. Consequently, the water to be cooled that is discharged from the first opening of the inlet pipe 110 has its flow direction changed by the closed end of the cooling pipe 120, which is covered by the inlet pipe 110, and can flow along the inner wall of the cooling pipe 120.

[0046] The water to be cooled, flowing along the inner wall of the cooling pipe 120, can flow radially through a first passage formed at the inlet 11 end, penetrating outward, that is, toward the inner wall of the housing 10. The water to be cooled, having passed through the first passage, flows again in the opposite direction along the inner wall of the housing 10, and can form a circulating flow along the ice spiral 30, as will be described later.

[0047] In other words, the inner wall of the housing 10 may include a spiral ice spiral 30 in a form that surrounds the inner circumferential surface of the housing 10.

[0048] The outer surface of the housing 10 may be provided with refrigerant circulation piping 20 formed along the ice spiral 30, that is, in a form that spirally surrounds the housing 10.

[0049] The refrigerant circulation piping 20 allows refrigerant to flow through it, thereby cooling the surrounding area. For example, the refrigerant circulation piping 20 corresponds to the evaporator among the compressor, condenser, evaporator, and expansion valve that constitute the refrigeration cycle. The evaporator evaporates the low-temperature, low-pressure liquid refrigerant flowing in from the expansion valve and exchanges heat with the surroundings. That is, the compressor, which draws in the low-temperature, low-pressure gaseous refrigerant evaporated in the evaporator, pressurizes the refrigerant. The pressurized refrigerant can be pressurized to a saturation pressure corresponding to the condensation temperature so that it can be condensed and liquefied in the condenser. The condenser exchanges heat with the surrounding air for the high-temperature, high-pressure gaseous refrigerant compressed and discharged by the compressor, causing the high-temperature gaseous refrigerant to release heat and condense into a liquid. The expansion valve can convert the high-temperature, high-pressure liquid refrigerant condensed and liquefied by the condenser back into a low-temperature, low-pressure liquid refrigerant through a throttling action.

[0050] The refrigerant circulation piping 20, which is spirally arranged around the outer surface of the housing 10, cools the water to be cooled on the inner surface of the housing 10 through the inlet 11. The configuration in which the housing 10 is surrounded by the refrigerant circulation piping 20 allows for the formation of spiral ice, or ice spiral 30.

[0051] As a result, the water to be cooled, which flows radially through the first passage formed at one end of the cooling pipe 120, comes into contact with the helical ice spiral 30 and can flow while rotating due to its shape.

[0052] The water to be cooled, which flows radially through the cooling pipe 120 via the first passage, flows along the spiral ice spiral 30, that is, along the f3 flow path shown in Figure 3, and the water to be cooled flowing along the ice spiral 30 can be guided to the drain port 12.

[0053] The ice spiral 30 formed by the refrigerant circulation piping 20 is preferably formed in a cross-sectional view, as shown in Figures 2 and 3, with space between adjacent ice formations along the longitudinal direction of the housing 10, thereby forming a flow path through which the water to be cooled can flow.

[0054] In other words, it is preferable to arrange the refrigerant circulation piping 20 on the outer circumferential surface of the housing 10 so that the ice spiral 30 is formed spaced apart from each other between adjacent ice formations along the longitudinal direction of the vertical cross-section of the housing 10.

[0055] As a result, the water to be cooled flows toward the drain port 12 while in contact with the surface of the spiral ice spiral 30, and the contact time with the ice increases and the contact area with the ice widens, thereby increasing the heat exchange efficiency and improving the cooling efficiency of the water to be cooled.

[0056] The ice spiral 30 may be formed to protrude inward from the housing 10, as shown in Figures 2 and 3. The inner end of the protruding ice spiral 30 is preferably formed to extend to the outer wall of the cooling pipe 120, or to at least a portion of the inside of the cooling pipe 120, and not to extend inside the water inlet pipe 110. In other words, it is preferable that the ice spiral 30 be formed in an area excluding the inside of the water inlet pipe 110.

[0057] This disclosure, without particular limitation, provides for a first passage (not shown) formed at one end of the cooling pipe 120, i.e., the end on the inlet 11 side, which penetrates the pipe wall. The first passage can be configured to allow the water to be cooled, which has flowed along the longitudinal direction of the cooling pipe 120, to flow radially toward the inner wall of the housing 10.

[0058] The first passage may be configured to have a large number of micropores. It is preferable to configure the passage so that the water to be cooled can be finely sprayed through it.

[0059] The cooling efficiency of the water to be cooled can be improved by increasing the contact area of ​​the ice spiral 30 with the surface of the water that is finely sprayed after passing through the first passage.

[0060] In a cooling device according to one embodiment of the present disclosure, the flow path of the water to be cooled formed during the process in which the water to be cooled flows in through the inlet 11 and is discharged through the outlet 12 is described as shown in Figure 3.

[0061] As shown in Figure 3, in a cooling device according to one embodiment of the present disclosure, the water to be cooled that flows in through the inlet 11 flows along the water inlet pipe 110 to form a flow path f1.

[0062] The water to be cooled, which flows in through the inlet 11 provided at the first end of the inlet pipe 110, flows along the longitudinal direction of the inlet pipe 110 and is discharged from the first opening 111 at the second end. The water to be cooled discharged from the first opening 111 flows again in the opposite direction along the longitudinal direction of the cooling pipe 120, which covers the second end, forming a flow path f2.

[0063] The water to be cooled, flowing internally along the inlet pipe 110 and cooling pipe 120, does not directly contact the ice spiral 30, but is pre-cooled by the cold air formed by the refrigerant circulation piping 20 and the ice spiral 30.

[0064] Subsequently, the water to be cooled, which flows radially through the first passage formed at the inlet 11 end of the cooling pipe 120, rotates along the spiral ice spiral 30 toward the drain port 12, thereby forming the f3 flow path. At this time, the water to be cooled is concentratedly cooled by coming into direct contact with the ice spiral 30.

[0065] In this way, the water to be cooled, which flows into the housing 10 through the inlet 11, is cooled in a short time by going through pre-cooling and concentrated cooling processes.

[0066] Figure 4 is a cross-sectional view of a cooling device according to another embodiment of the present disclosure. Figure 5 is a diagram showing the state in which the fluid flows along the flow path in the cooling device of Figure 4. Figure 6 is a cross-sectional view of the cooling device of Figure 4.

[0067] As shown in Figures 4 and 6, a cooling device according to yet another embodiment of the present disclosure may include a first inner pipe 115 and a second inner pipe 125 provided between the cooling pipe 120 and the housing 10. The first and second inner pipes 115 and 125 are arranged sequentially such that the first inner pipe 115 forms the inner shell and the second inner pipe 125 forms the outer shell.

[0068] A second opening 115a may be formed at the second end of the first inner pipe 115, i.e., the end on the drain port 12 side. A second passage that penetrates the pipe wall may be provided at the first end of the second inner pipe 125, i.e., the end on the inlet 11 side. The second passage may have a number of micropores formed in it, similar to the first passage.

[0069] In this embodiment, the ice spiral 30 is formed projecting inward from the inner wall of the housing 10. Preferably, the inner end of the projecting ice spiral 30 extends beyond the second inner pipe 125 to the outer wall of the first inner pipe 115.

[0070] In the cooling device according to this embodiment, the flow path of the water to be cooled, formed during the process in which the water to be cooled flows in through the inlet 11 and is discharged from the drain port 12, is as shown in Figure 5.

[0071] As shown in Figure 5, in the cooling device according to this embodiment, the water to be cooled that flows in through the inlet 11 flows along the water inlet pipe 110 to form a flow path f1.

[0072] The water to be cooled, which flows in through the inlet 11 provided at the first end of the inlet pipe 110, flows along the longitudinal direction of the inlet pipe 110 and is discharged through the first opening 111 provided at the second end. At this time, the closed second end of the cooling pipe 120, which covers the second end of the inlet pipe 110, changes direction, and the water flows along the longitudinal direction of the cooling pipe 120 to form a flow path f2.

[0073] Subsequently, the water to be cooled, which has flowed radially through the first passage formed at the inlet 11 end of the cooling pipe 120, can flow into the first inner pipe 115. The water to be cooled that has flowed into the first inner pipe 115 flows along the longitudinal direction of the first inner pipe 115 to form a flow path f3, and is then discharged from the second opening 115a provided at the other end of the first inner pipe 115.

[0074] The water to be cooled flowing inside the inlet pipe 110, the cooling pipe 120, and the first inner pipe 115 does not come into direct contact with the ice spiral 30, but is pre-cooled by the cold air formed by the refrigerant circulation pipe 20 and the ice spiral 30.

[0075] The water to be cooled, discharged from the second opening 115a at the second end of the first inner pipe 115, flows along the longitudinal direction of the inner wall of the second inner pipe 125 and can rotate along the ice spiral 30 formed on the inner wall of the second inner pipe 125 to form a flow path f41. Subsequently, it can flow into the inner wall of the housing 10 through a second passage formed through the pipe wall at one end of the second inner pipe 125.

[0076] The water to be cooled, which flows into the inner wall of the housing 10 via the second passage, flows along the longitudinal direction of the inner wall of the housing 10 and can rotate along the ice spiral 30 formed on the inner wall of the housing 10 to form the f42 flow path. The water to be cooled is then discharged from the drain port 12.

[0077] In this embodiment, after pre-cooling, the cooling water can reciprocate in direct contact with the ice spiral 30 along the f41 and f42 channels, thus further increasing the cooling efficiency through repeated concentrated cooling processes.

[0078] Since the first and second inner pipes 115, 125, the cooling pipe 120, and the water inlet pipe 110 are arranged overlapping inside the housing 10, even if supercooling occurs due to the refrigerant circulation piping 20, it is possible to prevent ice from completely freezing up to the water inlet pipe 110.

[0079] As shown in Figures 4 to 6, an insulating material 40 may be provided on the outer surface of the housing 10 of the cooling device according to one embodiment of the present disclosure, so as to surround the housing 10.

[0080] The insulating material 40 is not limited in any particular material, as long as it can form an insulating layer that prevents heat from being transferred between the inside and the outside.

[0081] In one embodiment of this disclosure, the drain port 12 may also discharge chilled water from which the water being cooled has been cooled. However, it is necessary to adjust the temperature of the chilled water discharged through the drain port 12.

[0082] Accordingly, a valve (not shown) may be provided in the drain port 12 according to one embodiment of the present disclosure. In this case, the valve can mix the cold water discharged from the drain port 12 with a fluid at a higher temperature than the cold water, specifically the water to be cooled, and discharge the mixed water whose temperature has been adjusted by the mixing.

[0083] In this case, the flow rate of the fluid mixed with the cold water can be adjusted by the degree to which the valve is opened or closed, and the temperature of the mixed water discharged from the valve can be adjusted.

[0084] In the above embodiment, when the water to be cooled is introduced into the inlet 11 of the housing 10, the cooled water is discharged at the drain 12. However, according to yet another embodiment of the present disclosure, the water to be cooled can be introduced into the drain 12 and the cooled water can be discharged at the inlet 11.

[0085] Instead of pre-cooling followed by concentrated cooling, the cooling process can be reversed: the water to be cooled is introduced through the drain port 12 to first bring it into contact with the surface of the ice spiral 30 for concentrated cooling, and then the cold water is discharged through the inlet pipe 11 to the outlet 11. In this case, there is an effect of reducing the temperature deviation of the discharged cold water.

[0086] The water to be cooled can flow into or cooled water can be discharged at the inlet 11 of the housing 10, and at the same time, cooled water can be discharged or the water to be cooled can flow into the drain port 12 of the housing 10.

[0087] In the above embodiment of the cooling device, the housing 10 is described as having an inlet 11 on the first end and a drain port 12 on the second end. However, in another embodiment of the cooling device of this disclosure, the housing 10 may have both an inlet 11 and a drain port 12 on one end.

[0088] Figure 8 shows the external appearance of a cooling device according to another embodiment of the present disclosure. Figure 9 shows a longitudinal cross-sectional view of a cooling device according to another embodiment of the present disclosure.

[0089] As shown in Figures 8 and 9, the water to be cooled that flows into the inlet 11 located at one end of the housing 10 is guided back and forth at least once inside the housing 10 to cool, and then discharged from the drain port 12 located in the same direction as the inlet 11.

[0090] If both an inlet 11 and a drain 12 are provided on one end of the housing 10, the inside of the housing 10 may also be provided with an inlet pipe 110, a cooling pipe 120, and an odd number of third inner pipes 130.

[0091] As a basic example, as shown in Figure 9, the housing 10 may be provided with an inlet pipe 110 having an inlet 11 into which the water to be cooled flows, a third inner pipe 130 spaced apart from the inlet pipe 110, and a cooling pipe 120 spaced apart from the third inner pipe 130.

[0092] As a result, the water to be cooled flowing along the inlet pipe 110, the third inner pipe 130, and the cooling pipe 120 is pre-cooled, rotates along the ice spiral 30 formed spirally on the inner wall of the housing 10 for concentrated cooling, and then discharged through the drain port 12 provided on the outside of the cooling pipe 120.

[0093] As described above, when the water to be cooled flows into the drain port 12, in reverse order, the water to be cooled is pre-cooled by rotating along the ice spiral 30 formed spirally on the inner wall of the housing 10, then flows along the cooling pipe 120, the third inner pipe 130, and the inlet pipe 110 for concentrated cooling, and then discharged through the inlet 11 of the inlet pipe 110.

[0094] The housing 10 is provided with an inlet pipe 110, a third inner pipe 130, and a cooling pipe 120, and at least one cover member 50a, 50b may be provided to selectively block one end or the other end of at least one of the inlet pipe 110, the third inner pipe 130, and the cooling pipe 120 in order to form a flow of the water to be cooled as shown in Figure 9.

[0095] In one embodiment of the present disclosure, the housing 10 may include at least one air hole for exhausting the air filled inside to the outside. At least one air hole may be formed in the cover members 50a, 50b.
