The specific implementation mode is as follows:

the present invention will be further described with reference to the following specific embodiments and accompanying drawings.

The utility model relates to an improved generation wine cooler, it is shown in figure 1, this is the embodiment one of the utility model. The first embodiment includes: the heat exchanger comprises a shell 1 and a heat exchange assembly arranged in the shell 1, wherein an inlet 11 and an outlet 12 are respectively arranged at the upper end and the lower end of the shell 1, and a cooling liquid outlet 13 and a cooling liquid inlet 14 are respectively arranged at the upper end and the lower end of the shell 1.

Two ends of the condenser pipe 22 are respectively communicated with a condensation water inlet channel 23 and a condensation water outlet channel 24 which are positioned at two sides, wherein the condensation water inlet channel 23 is communicated with a cooling channel outlet of the cooling unit 3, and the condensation water outlet channel 24 is communicated with the cooling liquid outlet 13; the condensate inlet passage 23, the pipes of the condenser pipe 22, and the condensate outlet passage 23 constitute a cooling passage of the condensing unit 2. The space outside the condensation pipe 22 in the condensation unit 2 is communicated with the inlet 11 and the wine passage inlet of the cooling unit 3, and the space outside the condensation pipe 22 forms the wine passage of the condensation unit 2.

When the condensing unit 2 in the first embodiment works, the cooling liquid enters the condensation water inlet channel 23, then enters the condensation water outlet channel 24 through the condensation pipe 22, along with the entering of the cooling liquid, the liquid level of the cooling liquid in the whole condensing unit 2 is raised, and finally the cooling liquid flows out from the cooling liquid outlet 13 at a high position. At the same time, wine vapor enters through the inlet 11 and runs from top to bottom through the space outside the condenser tube 22 under the action of the vapor pressure and the self-weight. After the wine vapor meets the condensing pipe 22, the wine vapor meets the condensing pipe and is condensed into liquid and drops downwards, and in the flowing process of the cooling liquid, the heat of the condensing pipe 22 is taken away, so that the heat exchange effect is realized. Thereby realizing the purpose of condensing the wine vapor.

In order to improve the heat exchange efficiency, the surface of the condensation pipe 22 is provided with the heat radiating fins 220, and the heat exchange area can be increased through the heat radiating fins 220, so that the condensation speed of the wine steam is further improved.

The cooling tube outlets 312 of all the cooling tubes 31 communicate with the wine passage in the supercooling unit 4, and the tubes of the cooling tubes 31 constitute the wine passage of the cooling unit 3. Referring to fig. 1, a plurality of cooling tubes 31 are longitudinally distributed, and when the wine vapor is condensed into a liquid state in the condensing unit 2, the wine vapor is collected at the bottom of the condensing unit 2, flows into the cooling tubes 31 through the cooling tube inlets 311, and then flows downward into the supercooling unit 4.

The cooling passage of the cooling unit 3 is constituted by a space outside the cooling pipe 31. The space outside the cooling pipe 31 in the cooling unit 3 is communicated with the cooling channel inlet in the condensing unit 2 through the upper end connecting pipe 5, and the space outside the cooling pipe 31 is communicated with the cooling channel outlet of the supercooling unit 4 through the lower end connecting pipe 6.

When the cooling unit 3 in the first embodiment works, the cooling liquid firstly enters the cooling unit 3 through the lower end connecting pipe 6, and the cooling liquid gradually fills the space outside the whole cooling pipe 31, so that the cooling pipe 31 is covered by the cooling liquid, and when the condensed wine flows into the cooling pipe 31, the heat of the condensed wine is transferred to the outside cooling liquid through the cooling pipe 31, thereby realizing heat exchange, reducing the temperature of the liquid wine, and realizing the purpose of cooling.

Of course, in order to further improve the heat exchange efficiency of the cooling pipe 31, a fin for heat dissipation may be provided on the surface of the cooling pipe 31.

The supercooling unit 4 in the first embodiment includes a hopper 41. The wine bucket 41 is communicated with the outlet of the wine channel of the cooling unit 3, namely the wine bucket 41 is communicated with the cooling pipe inlet 311 of the cooling pipe 31, so that the wine cooled by the cooling unit 3 can directly enter the wine bucket 41. The shape of the hopper 41 is not limited as long as it has a certain cavity for containing liquid wine. In order to ensure that the liquid wine can flow out completely, the hopper outlet 411 of the hopper 41 should be arranged at the lowest position. The wine bucket 41 in the first embodiment has an arc shape, and the lowest position of the wine bucket is provided with a wine bucket outlet 411 communicated with the outlet 12. The inner space of the hopper 41 constitutes a wine passage of the supercooling unit 4. A supercooling space 42 is formed at the periphery of the wine bucket 41, the supercooling space 42 is communicated with the cooling liquid inlet 14, the supercooling space 42 is communicated with the cooling channel of the cooling unit 3 through the lower end connecting pipe 6, and the supercooling space 42 forms the cooling channel of the supercooling unit.

In the first embodiment, when the supercooling unit 4 operates, the cooling liquid enters from the cooling liquid inlet 14 located at a low position, and the wine holding bucket 41 is covered by the cooling liquid along with the continuous entering of the cooling liquid, that is, the wine holding bucket 41 is completely immersed in the cooling liquid. Since the cooling liquid just enters from the cooling liquid inlet 14 at the lowest temperature, the liquid wine in the wine bucket 41 can be further cooled, and the supercooling of the liquid wine is realized.

In combination with the above, the working procedure of this embodiment is as follows:

cooling liquid: first, the cooling liquid enters the supercooling space 42 as the cooling channel of the supercooling unit 4 through the cooling liquid inlet 14, and the cooling liquid has the lowest temperature, so that the liquid wine in the wine holding hopper 41 is cooled, and the further supercooling of the liquid wine is realized. Secondly, the cooling liquid will enter the cooling channel in the cooling unit 3, i.e. the outer space of the cooling tubes 31 in the cooling unit 3, from the bottom up through the lower end connecting tube 6. At this time, after the cooling liquid passes through the supercooling unit 4, the temperature is raised, but the cooling liquid is still at a low temperature, and the cooling liquid can absorb the heat generated by the cooling pipe 31, so that the liquid wine in the cooling pipe 31 is cooled. Then, the cooling liquid continues to enter the cooling channel in the condensing unit 2 from bottom to top through the upper end connecting pipe 5, namely, the cooling liquid first enters the condensation water inlet channel 23 in the condensing unit 2 and then enters the condensation water outlet channel 24 through the condensing pipe 22. In the process, the temperature of the cooling liquid is raised, but the temperature of the cooling liquid is lower than that of the wine vapor, so that the wine vapor is condensed into a liquid state on the surface of the condensation pipe 22. Finally, the cooling liquid after condensation of the wine vapor flows out through the cooling liquid outlet 13 at a high position. The cooling liquid after flowing out can be cooled by an external cooling tower and other devices, and then enters the cooling liquid through the cooling liquid inlet 14 again, so that the recycling of the cooling liquid is realized.

Wine: firstly, wine vapor enters a wine channel in the condensing unit 2 through the inlet 11, namely, enters a space outside the condensing pipe 22, and the wine vapor is condensed into liquid wine after contacting the condensing pipe 22, and drops downwards to be collected at the bottom of the condensing unit 2. Then, the condensed liquid wine enters the wine passage of the cooling unit, namely, enters the cooling pipe 31 through the cooling pipe inlet 311, and in the process of flowing downwards along the cooling pipe 31, the condensed liquid wine transfers heat to the external cooling liquid through the cooling pipe 31, so that the cooling effect of the liquid wine is realized, and the paper enters the wine passage of the supercooling unit 4 through the cooling pipe outlet 312. Finally, the liquid wine entering the wine bucket 41 of the supercooling unit 4 is further supercooled by the cooling liquid, and finally flows out through the wine bucket outlet 411 and flows out through the outlet 12 to obtain the required low-temperature liquid wine.

Because the cooling liquid is recycled, after the cooling liquid is used for a certain time, impurities are inevitably mixed, and the whole wine cooler is polluted, so that the wine cooler needs to be cleaned regularly. For this purpose, the bottom plate of the supercooling unit 4 in the first embodiment adopts an inclined plate, so that the cooling liquid inlet 14 is located at the lowest point of the cooling liquid channel of the whole supercooling unit 4, which can ensure that all the sediment in the cleaning process can flow out through the cooling liquid inlet 14, and ensure the cleaning effect.

Through the aforesaid can see, the utility model provides a heat exchange assemblies includes condensation unit 2, cooling unit 3 and the tertiary heat exchange unit of supercooling unit 4, and wine is top-down and cools down gradually, and the coolant liquid heaies up gradually from bottom to top, and at this in-process, wine and coolant liquid realize thermal exchange, realize high-efficient, the condensation cooling of wine steam, and simultaneously, the coolant liquid also realizes the heat recovery of maximum efficiency through tertiary heat exchange.

Therefore, in order to improve the heat exchange efficiency, the heat exchanger can be further improved on the basis of the first embodiment.

See fig. 2, it is that this is embodiment two of the present invention, in this embodiment two, condensing unit 2 still adopts shell-and-tube heat exchanger, and it includes at least one condenser pipe 22, and this condenser pipe 22 is the reciprocal state of bending, and the port at its both ends communicates with cooling unit 3's cooling channel export and coolant outlet 13 respectively, and the pipeline of condenser pipe 22 constitutes this condensing unit 2's cooling channel. Compared with the first embodiment, the first embodiment has the disadvantages that the condensation pipe 22 in the first embodiment is composed of a plurality of pipes distributed horizontally, and two ends of the condensation pipe are required to be communicated with the condensation water outlet channel 24 through the condensation water inlet channel 23, so that the cooling liquid has a slow or delayed flow rate locally, the temperature of the whole cooling liquid is not increased step by step, and the local heat exchange is not uniform. And in the second embodiment, the condenser pipe 22 bent back and forth is adopted, so that the condensation water inlet channel 23 and the condensation water outlet channel 24 can be omitted, the cooling liquid is ensured to flow along the condenser pipe 22 from bottom to top, and the wine steam outside the condenser pipe 22 is subjected to heat exchange step by step, so that the heat exchange efficiency is improved. If a plurality of condensation pipes 22 are adopted, the water inlet of each condensation pipe 22 is positioned at the lowest point and can be directly communicated with the upper end connecting pipe 5, and the water outlet of each condensation pipe is positioned at the highest point and can be directly communicated with the cooling liquid outlet 13.

The cooling unit 3 in the second embodiment employs a shell-and-tube heat exchanger, but compared to the first embodiment, the external space of the cooling tube 31 in the second embodiment is divided into bent channels by the partition plate 32. The channel formed by separating the partition plates 32 can ensure that the cooling liquid intelligently flows from bottom to top along the channel, so that the fluidity of the cooling liquid is ensured, the conditions of insufficient fluidity and temperature unevenness caused by hysteresis of the cooling liquid in the first embodiment can be avoided, and a better heat exchange effect is realized.

Referring to fig. 3, this is a third embodiment of the present invention, and in the third embodiment, the condensing unit 2 employs a plate-shell type heat exchanger 21. The plate-shell heat exchanger 21 is formed by connecting a plurality of plate shells in sequence, wherein the plate layer channel is formed in the space inside the plate shells, and the shell layer channel is formed in the space outside the plate shells. Wherein the plate-layer channel of the plate-shell type heat exchanger 21 is used as a cooling channel of the condensing unit 2 and is respectively communicated with a cooling channel outlet of the cooling unit 3 and a cooling liquid outlet 13; the shell channel of the plate-shell type heat exchanger 21 is used as a wine channel of the condensation unit 2 and is respectively communicated with the inlet 11 and the wine channel inlet of the cooling unit 3. The plate-shell type heat exchanger exchanges heat through the large-area plate shell, so that the heat exchange efficiency is higher than that of a shell-and-tube type heat exchanger, and the heat exchange efficiency can be further improved.

In the first and second embodiments, the vertical cooling pipe 31 is adopted, and in the process that the liquid wine flows downwards through the cooling pipe 31, heat exchange needs to be realized by contacting with the pipe wall of the cooling pipe 31, but the cooling pipe 31 which is vertically distributed is adopted, so that the liquid wine can directly drip from the channel, the dripping speed is too high, even the liquid wine does not contact with the pipe wall, and thus no timely heat exchange is caused. At the same time, the wine vapor in the condensation unit 2 without condensation may also go directly down into the supercooling unit 4 through the cooling pipe 31. This may end up in the event that the temperature of the liquid wine exiting the outlet 12 is too high.

In contrast, in the third embodiment, the cooling unit 3 includes a cooling pipe 31 bent back and forth or spirally wound from top to bottom, the ports at the two ends of the cooling pipe 31 are respectively communicated with the wine passage in the condensing unit 2 and the wine passage in the supercooling unit 4, and the pipe of the cooling pipe 31 forms the wine passage of the cooling unit 3. The advantages of adopting this structure are: after entering the cooling pipe 31, the liquid wine condensed by the condensing unit 2 can only flow downwards along the cooling pipe 31 in a spiral manner, and the flow speed is reduced, so that the liquid wine can be ensured to be in full contact with and exchange heat with the cooling pipe 31. Meanwhile, even if some wine vapor enters the cooling pipe 31, the wine vapor is condensed into liquid wine and cooled down while moving in the cooling pipe.

As shown in fig. 3, in the third embodiment, in order to collect the liquid wine in the condensing unit 2 without generating residue, the bottom plate of the condensing unit 2 is designed to be concave, that is, the lowest position of the bottom plate of the condensing unit 2 is ensured to be communicated with the port of the cooling pipe 31, so that all the condensed liquid wine can smoothly enter the cooling pipe 31, and no residue is formed in the condensing unit 2.

Of course, the above description is only a specific embodiment of the present invention, and not intended to limit the scope of the present invention, and the condensing unit, the cooling unit, and the subcooling unit in the three embodiments may be combined with each other to form a desired condenser as required. All equivalent changes or modifications made according to the structure, characteristics and principle of the present invention should be included in the claims of the present invention.
