The end caps 31 are detachably connected to the end portions 21 of the barrel 2 along an axis X, each of the end caps 31 has a tubular body portion 312 surrounding the axis X and defining a hole 311 , and a body portion 314 surrounding the tubular body portion 312 and defining a loop 313 with the tubular body portion 312 . The body portion 314 also defines a heat absorbing flow path 315 with an opening facing outwards for fluid to pass through, and has two opposite ring edges 316 . Each of the ring edges 316 defines an opening 317 . One of the openings 317 communicates with the hole 311 , and the other of the openings 317 communicates with the ring 313 . The hole 311 is not in communication with the ring 313 .

Referring to Fig. 2, Fig. 4 and Fig. 5, the heat exchanging element 4 is inserted in the cylindrical element 2 along the axis X, and is connected to the tube body portion 312 of the end caps 31, and includes a tube wall 42 surrounding the axis X and defining a tube 41, and several fins 43 extending from the tube wall 42. The tube wall 43 and the barrel 2 also define a vortex chamber 44 . The duct 41 and each of the holes 311 and the corresponding openings 317 of the end cap 31 define a first channel for fluid to pass through. The vortex chamber 44 defines a second channel suitable for fluid passing through the annular channel 313 and the corresponding opening 317 of each of the end caps 31 . In this embodiment, the fins 43 respectively extend along a curve from the inner surface and the outer surface of the tube wall 42 in a direction opposite to the tube wall 42 .

Referring to Figure 2, Figure 4 and Figure 6, the cyclone ring 5 surrounds the axis X and is installed Between the heat exchange element 4 , the cylinder element 2 and one of the end caps 31 , there are several vanes 51 formed on the outer surface and suitable for guiding the fluid to generate vortex in the second channel.

Referring to FIG. 2 and FIG. 4 , in this embodiment, each of the condensing units 6 is installed on the body portion 314 of the respective end cover 31 , and includes a cooling chip module 61 and a heat releasing module 62 . The cooling chip module 61 has a heat absorbing panel 611 facing the body portion 314 for absorbing heat energy, a heat releasing panel 612 opposite to the body portion 314 for releasing heat energy, and a cooling chip 613 sandwiched between the heat absorbing panel 611 and the heat releasing panel 612 . The heat dissipation module 62 is connected to the heat dissipation panel 612 without contacting the respective end caps 31 , and defines a heat dissipation flow path 621 opening toward the heat dissipation panel 612 and suitable for passing fluid.

It is worth noting that the aforementioned fluid may be liquid, or gas, or a mixture of liquid and gas, or a mixture of liquid and particles, or a mixture of gas and particles, or a mixture of liquid, gas and particles. The advantage of mixing liquid and gas is that the flow speed of the liquid can be increased by the gas pressure.

In addition, in the present embodiment, the tube part 2, the end caps 31, the heat exchange part 4, the cyclone ring part 5 and the heat radiation module 62 are respectively made of aluminum material, or other metal materials with high thermal conductivity, such as copper material.

Referring to Fig. 4, Fig. 5 and Fig. 6, when the condensing units 6 are connected to direct current, they can absorb heat energy with the heat absorbing panel 611 and release heat with the heat releasing panel 612 through the Peltier Effect of each cooling chip module 61. Therefore, when the heat dissipation panel 612 is not in contact with the end covers 31 or the barrel 2 , the transfer of heat energy to the respective end covers 31 can be reduced and delayed. Thereby, the heat energy of the end caps 31 and the heat energy of the fluid passing through the heat-absorbing flow paths 315 will be absorbed by the heat-absorbing panels 611 of the cooling chip modules 61, and the temperature of the end caps 31 will be greatly reduced.

At this time, the heat radiation panels 612 of the cooling chip modules 61 will release heat energy outwards. In this embodiment, the released heat energy can exchange heat with the heat radiation modules 62 and the fluid passing through the heat radiation flow path 621 to achieve the effect of cooling.

When the high-temperature fluid enters and exits the condensing device of the present invention from the first channel as shown by the dotted arrow, it will first pass through the cyclone ring 5 to generate a vortex in the vortex chamber 44, and flow around the heat exchange element 4 along the fins 43 on the outer surface of the heat exchange element 4. In this way, the high-temperature fluid can conduct heat exchange with the cylinder part 2, the end caps 31, the heat exchange part 4, and the cyclone ring part 5, thereby achieving the purpose of rapid and substantial cooling.

When the low-temperature fluid or the same high-temperature fluid enters and exits the condensing device of the present invention through the second channel as shown by the solid arrow, it will not only contact the heat-absorbing panel 611 of the condensing unit 6, but also contact the end covers 31 and the fins 43 on the inner surface of the heat exchange element 4 during the flow process. In this way, the fluid in the second flow channel is heat-exchanged with the heat-absorbing panels 611, the end covers 31 and the fins 43 on the inner surface of the heat exchange element 4. At this time, if the solid arrow indicates a low-temperature fluid, the first flow can be further reduced. If the fluid temperature in the channel is shown by the solid arrow as a high-temperature fluid, the purpose of cooling can also be achieved.

It is worth noting that since the temperature of the fluid will be greatly reduced, when the fluid is a gas, the gas can also be condensed into water, thereby reducing the humidity of the gas.

It should be noted that the number of the condensing units 6 is not limited to two, and the shape of each end cover 31 is not limited to being a cylinder. In other variations of this embodiment, as shown in FIGS. 1 heat-absorbing module 63. The heat-absorbing module 63 defines a heat-absorbing channel 631 suitable for passing fluid. In this way, the effects of heat absorption and heat release can also be achieved.

Referring to FIG. 9 and FIG. 10 , the present invention can form a condensing system with a plurality of condensing devices and a connecting device 7 .

The connection device 7 includes several engagement groups 71 . Each connecting group 71 is selectively and detachably connected to two adjacent condensing devices. In this embodiment, each connecting group 71 is composed of a pipe and at least one C-shaped fastener, or other components capable of connecting two adjacent condensing devices. Since those skilled in the art can infer extended details based on the above description, no further description is given.

Thereby, when assembling, as shown in FIG. 9, through these connecting groups 71 string Connect the condensing devices, or as shown in FIG. 10 , connect the condensing devices in parallel through the connecting groups 71 to further reduce the temperature of the fluid.

It should be noted that the condensing devices of the present invention are not limited to being connected in series or in parallel with each other. In other variations of this embodiment, as shown in FIG. 11 and FIG. 12 , more than one filter device 8 may be connected in series through the connecting groups 71 to capture water vapor, oil mist, or dust, or particles in the fluid. The aforementioned filter device 8 may be the cyclone separation filter module disclosed in the Republic of China Patent No. I589344, or the cyclone filter device disclosed in the Republic of China Patent Publication No. 201912230. Since it is not a technical feature of the present case, and those skilled in the art can infer the expanded details based on the above description, no further description is given.
