As can be seen in fig. 1, the fan 21 operates to generate a wind flow. The direction of the wind flow is indicated by arrows in fig. 1. The air flow is discharged after heat exchange by the filler 22, and due to the effect of the water sowing heat exchange device 10, the air flow exchanges heat with the water flow with the temperature rising in the filler 22, so that heat is discharged by the fan 21 along with the air flow, and the refrigerant after heat exchange (after heat release after condensation) enters the heat exchanger 25 through the throttling device 26.

The water flow with the raised temperature flows out from the spray ports 110 of each water sowing vertical pipe 11b, and then water is sown. The refrigerant after heat release of condensation flows out from the other refrigerant collecting lateral tube 41. Because all the water-sowing vertical pipes 11b are mutually communicated under the action of the two water-collecting transverse pipes 112, when the water flow is turbulent, the water flow is not faster than the water flow from the spray ports 110, and the water flows in the plurality of water-sowing vertical pipes 11b, so that the heat exchange efficiency is improved.
Alternatively, in one possible implementation, the water inlet pipe 111 is vertically distributed to the coolant collecting lateral pipe 41. The refrigerant outlet 81 is located between the inlet pipe 111 and the refrigerant inlet 80. It should be noted that, the refrigerant collecting transverse tube 41 as the refrigerant inlet 80 is far away from the water inlet tube 111, so that the design is beneficial to the refrigerant to exchange heat with the water flow sufficiently and the heat exchange efficiency is improved.
Alternatively, in one possible implementation, another specific structure of the water sowing cavity 11 and the heat exchange cavity 12 is provided, and the shapes thereof can be seen in fig. 5, 6 and 7, wherein fig. 5 shows a specific structure of the water sowing heat exchange device 10, fig. 6 shows a specific structure of the water sowing cavity 11, and fig. 7 shows a specific structure of the heat exchange cavity 12.
The water sowing cavity 11 comprises a water inlet pipe 111, and the water sowing pipe is an annular pipe body 11a. The diameters of the plurality of annular pipes 11a gradually decrease, the plurality of annular pipes 11a are concentrically distributed, and the water inlet pipe 111 communicates with each annular pipe 11a. The bottom surface of each annular tube 11a is formed with a spray opening 110, and ventilation holes 70 are formed between adjacent annular tubes 11a. Wherein, for the convenience of seeing the spray opening 110, fig. 3 is a bottom view of the water sowing cavity 11.
The heat exchange cavity 12 comprises a first refrigerant collecting pipe 31 and a second refrigerant collecting pipe 32, the heat exchange pipes are annular heat exchange pipes 33, the annular heat exchange pipes 33 are in one-to-one correspondence with the annular pipe body 11a and are positioned in the annular pipe body 11a, the first refrigerant collecting pipe 31 is communicated with an inlet of each annular heat exchange pipe 33, and the second refrigerant collecting pipe 32 is communicated with an outlet of each annular heat exchange pipe 33.

The water sowing cavity 11 includes a water inlet pipe 111 and a plurality of annular pipes 11a, the plurality of annular pipes 11a are concentrically arranged, and the water inlet pipe 111 is communicated with all the annular pipes 11a. Meanwhile, the annular heat exchange tubes 33 of the heat exchange cavity 12 are respectively placed in each annular tube body 11a, and the first refrigerant collecting pipe 31 and the second refrigerant collecting pipe 32 are communicated with all the annular heat exchange tubes 33 to respectively form a refrigerant inlet 80 and a refrigerant outlet 81. The water flow enters through one water inlet pipe 111, is dispersed into each annular pipe body 11a, and the refrigerant enters into each annular heat exchange pipe 33 through the first refrigerant collecting pipe 31. The water flow in each annular tube 11a exchanges heat with the annular heat exchange tube 33 disposed in the annular tube 11a, respectively. The water flow with the increased temperature flows out from the spray opening 110 of each annular pipe body 11a, and then water is sown. The refrigerant after heat release by condensation flows out from the second refrigerant header 32.
Optionally, in one possible implementation manner, the first refrigerant collecting pipe 31 and the second refrigerant collecting pipe 32 are arranged in parallel and spaced, and a symmetry line of the first refrigerant collecting pipe 31 and the second refrigerant collecting pipe 32 is located at one side of the annular pipe body 11a, and the water inlet pipe 111 is located at the other side of the annular pipe body 11a. It should be noted that, the above design makes the refrigerant be able to exchange heat with the water flow in the annular tube 11a sufficiently, which is beneficial to improving the heat exchange efficiency.
It should be noted that, in one possible implementation, the water sowing cavity 11 includes a first housing and a second housing, and a bottom surface of the first housing forms the spray opening 110. The heat exchange chamber 12 is sealed between the first housing and the second housing. In one case, the first and second housings may be bonded by a sealant, and in other cases, the first and second housings may be connected by other sealable structures. Through the water sowing cavity 11, the heat exchange cavity 12 can be easily assembled in the water sowing cavity 11, so that the manufacturing cost is reduced, and the popularization is easy.
It should be noted that, in one possible implementation, the heat exchange cavity 12 is supported in the inner cavity of the water sowing cavity 11 by a spiral flow guide bracket (not shown in the figure). The spiral diversion support is supported in the inner cavity of the water sowing cavity 11, so that water flow can form turbulence, the water flow can effectively wash the pipe wall, the heat exchange coefficient is improved, and the scaling possibility is reduced.
It should be noted that any of the above-described water-seeding heat exchange devices 10 may be applied to the refrigeration system 20.
It should be noted that, in this embodiment, another refrigeration system 20 is further provided, and fig. 8 is a schematic diagram of another refrigeration system 20 provided in this embodiment.
The refrigeration system 20 includes a fan 21, a filler 22, a water tank 23, a compressor 24, a heat exchanger 25, a throttling device 26, and the water-casting heat exchange device 10. The water-seeding heat exchange device 10, the packing 22 and the water tank 23 are arranged in the vertical direction, and the fan 21 is located at the side of the packing 22. Wherein, a water baffle 28 can be arranged between the fan 21 and the filler 22, and the water tank 23 is communicated with the water inlet 90 of the water sowing cavity 11 through a water pump 27. The heat exchange outlet of the heat exchanger 25 is connected with the refrigerant inlet 80 of the heat exchange cavity 12 through the compressor 24, and the refrigerant outlet 81 of the heat exchange cavity 12 is connected with the heat exchange inlet of the heat exchanger 25 through the throttling device 26.
As can be seen in fig. 1, the fan 21 operates to generate a wind flow. The direction of the wind flow is indicated by arrows in fig. 1. The wind flow enters the packing 22 from the side, and due to the effect of the water sowing heat exchange device 10, the wind flow exchanges heat with the water flow with the temperature rising in the packing 22, so that heat is discharged from the fan 21 along with the air flow, and the refrigerant after heat exchange (after heat release after condensation) enters the heat exchanger 25 through the throttling device 26.
In the present refrigeration system 20, the multicast water heat exchange device 10 may be of the configuration illustrated in fig. 9. Fig. 9 shows a specific structure of another water-seeding heat exchange device 10.
As can be seen in fig. 10, the water sowing cavity 11 includes a water sowing cavity 11c and a water inlet pipe 111, the water inlet pipe 111 is communicated with the water sowing cavity 11c, and a spray opening 110 is formed on the bottom surface of the water sowing cavity 11c, wherein, for convenience in viewing the spray opening 110, fig. 10 is a bottom view of the water sowing cavity 11 c. Fig. 11 shows a specific structure of another heat exchange cavity 12 according to this embodiment.
As can be seen from fig. 10, the heat exchange cavity 12 includes two refrigerant collecting transverse pipes 41 and a plurality of heat exchange risers 42, and the plurality of heat exchange risers 42 are disposed between the two refrigerant collecting transverse pipes 41 at intervals and are communicated with the two refrigerant collecting transverse pipes 41. A plurality of heat exchange standpipe 42 and two coolant collecting cross pipes 41 are positioned in the water sowing tank 11c, and the open ends of the coolant collecting cross pipes 41 penetrate through the side surface of the water sowing tank 11 c.
The water inlet pipe 111 forms the water inlet 90, and the openings of the two refrigerant collecting lateral pipes 41 define the refrigerant inlet 80 and the refrigerant outlet 81, respectively.
The water sowing cavity 11 comprises a water sowing cavity 11c and a water inlet pipe 111. All heat exchange standpipe 42 of the heat exchange cavity 12 are placed in the water sowing tank 11c, and two refrigerant collecting transverse pipes 41 respectively form a refrigerant inlet 80 and a refrigerant outlet 81. The water flow enters the water sowing tank 11c through a water inlet pipe 111, and the refrigerant enters the water sowing tank 11c through one of the refrigerant collecting transverse pipes 41. The water flow of the water sowing tank 11c exchanges heat with each heat exchange standpipe 42 inside the water sowing tank 11 c. The water flow with the increased temperature flows out from the spray opening 110, and then water is sown. The refrigerant after heat release of condensation flows out from the other refrigerant collecting lateral tube 41. Because the plurality of heat exchange vertical pipes 42 exchange heat with the water flow in the same water sowing tank 11c, the water flow can conduct heat with each heat exchange vertical pipe 42, which is beneficial to improving the heat exchange efficiency.
In the above-described refrigerating system 20, the air flow is discharged from the side surface through the fan 21 disposed on the side surface after the heat exchange of the filler 22, so that the water sowing tank 11c in the present embodiment does not affect the discharge of the air flow.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
