Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration, and particularly to a condensation device. Background Art

[0002] With the progress of technology, electronic devices have been widely developed, and the data processing function, storage function, and communication function of electronic devices have made great progress. During the operation of electronic devices, high heat will be generated. If the heat cannot be dissipated in time, it will cause the electronic devices to malfunction, and in severe cases, the electronic devices will be damaged.

[0003] Currently, generally, a fan is used to dissipate heat from electronic devices, or the electronic devices are directly immersed in a container with a heat dissipation medium for heat dissipation. When the electronic device is in the container with the heat dissipation medium, heat is transferred from the electronic device to the liquid, causing the liquid to boil and generate steam. The steam condenses on the condensation device to cool the circulating coolant, realizing the cooling process of the coolant.

[0004] The inventor found that there are at least the following problems in the prior art: In the condensation device in the prior art, generally, a condensation pipe is used to cool the steam. The steam condenses inside the condensation pipe, and the outside of the pipe is cooled by air or liquid. After the steam condenses, a layer of condensate film will be formed on the inner wall of the condensation pipe, which hinders the subsequent contact between the steam and the cold wall surface, reduces the contact area between the steam and the cold wall surface, and the condensation effect is poor. Summary of the Invention

[0005] In view of this, the present invention provides a condensation device, which improves the condensation efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A condensation device includes a condensation pipe. The condensation pipe includes a main pipe and a sub-pipe.

[0041] The present invention discloses a condensation device for gas - liquid separation, which improves the condensation efficiency.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0043] Refer to Figures 1 to 4 , the condensation device for gas - liquid separation of the present invention includes a condensation pipe. The condensation pipe includes a main pipe 2 and a sub - pipe 7. One end of the air inlet 1 of the main pipe 2 is communicated with the gas inlet of the condensation device, and the other end is communicated with the drain pipe 5. A first swirl device 3 is arranged in the main pipe 2, and a first gas collecting pipe 4 is arranged at the end of the first swirl device 3. The inlet end of the first gas collecting pipe 4 is communicated with the main pipe 2, the outlet end of the first gas collecting pipe 4 is communicated with the sub - pipe 7, and the end of the sub - pipe 7 is communicated with the drain pipe 5. In order to facilitate the gas to enter the first gas collecting pipe 4, the inlet end of the first gas collecting pipe 4 faces the exhaust end of the first swirl device 3, that is, the opening of the inlet end of the first gas collecting pipe 4 faces the flow direction of the fluid in the main pipe 2. The diameter of the first gas collecting pipe 4 is smaller than that of the main pipe 2, so as to facilitate the liquid layer 11 on the pipe wall to flow to the drain pipe 5.

[0044] Among them, the end of the first cyclone device 3 is the exhaust end of the first cyclone device 3. The outlet end of the first gas collecting pipe 4 is communicated with the starting end of the auxiliary pipe 7. The above-mentioned starting end and end are set according to the flow direction of the gas flow. The starting end is the position where the gas flow passes first, and the end is the position where the gas flow passes later. The starting end and end set below also refer to this description. The liquid outlet 6 of the drain pipe 5 is communicated with the liquid outlet of the condensing device.

[0045] In the condensing device for gas-liquid separation of the present invention, after the gas enters the main pipe 2 of the condensing pipe, the mixture of the gas and liquid droplets ( Figure 2 the circular particles at the front end of the first cyclone device 3 in it) passes through the first cyclone device 3. Under the action of the first cyclone device 3, the mixture of the gas and liquid droplets generates a swirl. Since the liquid has a larger density, the centrifugal force it receives is larger, and the required centrifugal radius is also larger. Therefore, the liquid mainly gathers on the inner wall of the main pipe 2 to form a liquid layer 11, and the liquid is discharged through the drain pipe 5. Most of the gas flow 10 enters the auxiliary pipe 7 through the first gas collecting pipe 4. In the condensing device for gas-liquid separation of the present invention, by setting the first cyclone device 3 to separate the gas-liquid mixture, the condensing efficiency is improved, the obtained condensed liquid is discharged as soon as possible, the dryness of the gas-liquid mixture is greatly improved, and the condensing efficiency of the gas is enhanced. By setting the auxiliary pipe 7 to further condense the gas, the condensing effect of the gas is improved.

[0046] Among them, the auxiliary pipe 7 includes at least one stage. In order to facilitate the gas-liquid separation of the gas-liquid mixture in the auxiliary pipe 7, a second cyclone device 8 is provided in at least one stage of the auxiliary pipe 7. A second cyclone device 8 is provided in the nth stage auxiliary pipe. The end of the second cyclone device 8 is provided with an (n + 1)th stage gas collecting pipe. The inlet end of the (n + 1)th stage gas collecting pipe is communicated with the nth stage auxiliary pipe. The inlet end of the (n + 1)th stage gas collecting pipe is coaxially arranged with the nth stage auxiliary pipe. The outlet end of the (n + 1)th stage gas collecting pipe is communicated with the starting end of the (n + 1)th stage auxiliary pipe. The end of the nth stage auxiliary pipe is communicated with the drain pipe 5. A second cyclone device 8 may or may not be provided in the last stage auxiliary pipe. When the second cyclone device 8 is not provided in the last stage auxiliary pipe, the outlet end of the last stage auxiliary pipe is only communicated with the drain pipe 5, and all the gas and liquid in the last stage auxiliary pipe flow into the drain pipe 5. It can be understood that when the auxiliary pipe 7 is provided with multiple stages, a second cyclone device 8 may be provided in each stage of the auxiliary pipe, or a second cyclone device 8 may be provided at an interval of one or more stages of the auxiliary pipe. This is not limited here.

[0047] In one embodiment, the auxiliary pipe 7 is provided with two levels. A second swirl device 8 is arranged in the first-level auxiliary pipe. A second gas collecting pipe 9 is arranged at the end of the second swirl device 8. The inlet end of the second gas collecting pipe 9 is communicated with the first-level auxiliary pipe, and the inlet end of the second gas collecting pipe 9 is coaxially arranged with the first-level auxiliary pipe. The outlet end of the second gas collecting pipe 9 is communicated with the starting end of the second-level auxiliary pipe. The end of the first-level auxiliary pipe is communicated with the drain pipe 5, and the end of the second-level auxiliary pipe is communicated with the drain pipe 5, so as to facilitate the condensed liquid to flow into the drain pipe 5. No second swirl device 8 is arranged in the second-level auxiliary pipe. Refer to Figure 1 .

[0048] In another embodiment, the auxiliary pipe 7 is provided with one level. A second swirl device 8 is arranged in the auxiliary pipe 7. By arranging the second swirl device 8, it is convenient for more droplets to be thrown towards the pipe wall under the action of centrifugal force. The end of the auxiliary pipe 7 is communicated with the drain pipe 5, so as to facilitate the condensed liquid to flow into the drain pipe 5.

[0049] Since the gas has a small density, the centrifugal force it receives is small, and the required centrifugal radius is also small. Therefore, the gas flow 10 mainly gathers at the central position of the main pipe 2. The inlet end of the first gas collecting pipe 4 is coaxially arranged with the main pipe 2, so as to facilitate the gas flow 10 to flow into the first gas collecting pipe 4, so that the gas can enter the auxiliary pipe 7 for further gas-liquid separation.

[0050] In order to improve the heat dissipation performance, a first heat dissipation rib 201 is arranged on the outer surface of the main pipe 2, and a second heat dissipation rib 701 is arranged on the outer surface of the auxiliary pipe 7. In order to condense the gas flowing into the drain pipe 5, a third heat dissipation rib 501 is arranged on the outer surface of the drain pipe 5.

[0051] Specifically, the first swirl device 3 includes a first support frame (not shown in the figure), a first rotating shaft 301 and a first spiral blade 302. The first rotating shaft 301 is rotatably connected to the first support frame, the first spiral blade 302 is fixedly connected to the first rotating shaft 301, the first rotating shaft 301 is arranged along the axis of the main pipe 2, and the first support frame is fixedly connected to the inner wall of the main pipe 2. The fixed connection here can be an interference connection or can be connected through a connecting piece.

[0052] Further, a plurality of first spiral blades 302 are arranged. The plurality of first spiral blades 302 are spirally arranged along the outer surface of the first rotating shaft 301. As Figure 3 shown, so as to facilitate the mixture of gas and droplets to generate swirl and move towards the end of the first swirl device 3 at the same time.

[0053] Similarly, the second swirling device 8 includes a second support frame, a second rotating shaft 801, and second helical blades 802. The second rotating shaft 801 is rotatably connected to the second support frame, and the second helical blades 802 are fixedly connected to the second rotating shaft 801. The second rotating shaft 801 is arranged along the axis of the auxiliary pipe 7, and the second support frame is fixedly connected to the inner wall of the auxiliary pipe 7. The fixed connection here can be an interference fit, or can be connected through a connecting member, or can also be other connection methods commonly used by those skilled in the art, which is not limited here.

[0054] Among them, a plurality of second helical blades 802 are provided, and the plurality of second helical blades 802 are spirally arranged along the outer surface of the second rotating shaft 801. The first swirling device 3 and the second swirling device 8 can be the same or different, which is specifically set by those skilled in the art according to actual needs.

[0055] In the gas-liquid separation condensation device of the present invention, a swirling device is provided in the condensation pipe, and a gas collecting pipe and a liquid discharge pipe 5 are provided. After the steam and the liquid droplets condensed from the steam pass through the swirling device in the pipe, the gas-liquid two-phase generates swirl. Under the action of centrifugal force, the condensed liquid droplets gather on the pipe wall of the condensation pipe and are discharged from the liquid discharge pipe 5, while the steam mainly gathers in the center of the condensation pipe and is transported to the next pipe section through the gas collecting pipe. The gas-liquid separation condensation device of the present invention can timely discharge the condensed liquid droplets, ensure the steam dryness on the pipe wall surface of the condensation pipe, will not hinder the subsequent contact between the steam and the cold wall surface, and improves the condensation efficiency.
