[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or indirectly on the other element. It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0034] Please also read Figure 1 and Figure 2 , the circulating water cooling device provided by the utility model is now described. The circulating water cooling device includes a cold water reservoir 1, a heat dissipation component 3 and a hot water reservoir 4; the outflow end of the cold water reservoir 1 is connected to the inflow end of the heat exchange device 2 through a first connecting pipe 11; a first delivery pump 5 is provided on the first connecting pipe 11; a second connecting pipe 21 is provided at the outflow end of the heat exchange device 2; the heat dissipation component 3 includes a turbine 31 whose inflow end is connected to the second connecting pipe 21, and a fan 33 connected to the turbine 31 through a connecting rod 32; a third connecting pipe 34 is provided at the outflow end of the turbine 31; the top surface of the hot water reservoir 4 is open, and corresponds to the fan blades of the fan 33 up and down; the inflow end of the hot water reservoir 4 is connected to the second connecting pipe 21 and the third connecting pipe 34 respectively; the outflow end of the hot water reservoir 4 is connected to the cold water reservoir 1 through a fourth connecting pipe 35; a second delivery pump 6 is provided on the fourth connecting pipe 35.

[0035] Specifically, after the cold water in the cold water reservoir 1 passes through the heat exchange device 2 for heat exchange, it takes away the heat at the heat exchange device 2 and discharges the hot water flow through the second connecting pipe 21. A part of the discharged hot water flow directly enters the hot water reservoir 4, and the other part enters the turbine 31 to drive the turbine 31 to rotate. The turbine 31 drives the fan 33 to rotate through the connecting rod 32 and the transmission 36, so that the fan 33 cools the hot water flow in the hot water reservoir 4 above the hot water reservoir 4; and the water flow discharged from the turbine 31 flows back to the second connecting pipe 21 again, and enters the hot water reservoir 4 for cooling; the hot water flow after the cooling treatment by the fan 33 is converted into a cold water flow again, and is transported to the cold water reservoir 1 for storage through the second delivery pump 6 for recirculation.

[0036] It should be understood that, since the radiation range of the fan 33 is limited, if the hot water flow discharged from the heat exchange device 2 is directly discharged into the cold water storage tank 1, the mixed water flow formed by the mixture of the cold water flow and the hot water flow will occupy a large volume, which is easy to exceed the wind guiding cooling range of the fan 33, thereby reducing the cooling effect; in the present application, by cooling the hot water flow separately, on the one hand, the problem of large volume occupied by the mixed water flow formed by the mixture of cold and hot water can be avoided, thereby improving the cooling effect; on the other hand, the hot water flow does not affect the delivery of the cold water flow, thereby ensuring that the cold water flow delivered to the heat exchange device 2 can take away a large amount of heat, thereby avoiding the problem of the mixed water flow after the mixture of cold and hot water failing to cool the heat exchange device 2 to the standard.

[0037] Compared with the prior art, the circulating water cooling device provided by the utility model can convert the kinetic energy of circulating water into the energy of the rotation of the fan 33 through the water turbine 31, so that the wind energy generated when the fan 33 rotates can cool the hot water flow discharged from the heat exchange device 2, thereby achieving the purpose of cooling; and, in the present application, the hot water flow and the cold water flow are respectively contained in the hot water storage tank 4 and the cold water storage tank 1, so that the hot water flow can be centrally cooled by the fan 33 without affecting the transportation of the cold water flow; the circulating water cooling device provided in the present application can drive the water turbine 31 to rotate through the circulating water, and the water turbine 31 drives the fan 33 to rotate, which can reduce the power load and significantly reduce the power consumption of electric energy to achieve the effect of energy saving.

[0038] See also Figure 1 In some possible embodiments, a water temperature sensor 7 is provided on the fourth connecting pipe 35 between the second delivery pump 6 and the hot water storage tank 4 .

[0039] By providing a water temperature sensor 7 , the cooling effect of the water flow in the hot water storage tank 4 is monitored in real time, and the temperature of the water flow delivered by the second delivery pump 6 is determined.

[0040] See also Figure 1In some embodiments, the outlet end of the second delivery pump 6 is also connected to the inlet end of the heat exchange device 2 through a fifth connecting pipe 61, and the fifth connecting pipe 61 is provided with a first control valve 611; the outlet end of the second delivery pump 6 is also connected to the top of the hot water storage tank 4 through a sixth connecting pipe 62, and the sixth connecting pipe 62 is provided with a second control valve 621.

[0041] It should be understood that after the fan 33 cools the water flow in the hot water reservoir 4, the temperature of the water flow discharged by the second delivery pump 6 can be monitored by the water temperature sensor 7. When the water flow temperature is still too high, the water flow can be circulated to the hot water reservoir 4 through the fifth connecting pipe 61 for cooling again, and after cooling to a preset temperature, it is delivered out of the hot water reservoir 4; the temperature of the delivered water flow has reached the temperature of the cold water flow and can enter the cold water reservoir 1 for storage; when the cold water flow rate required by the heat exchange device 2 is large and exceeds the discharge capacity of the cold water reservoir 1, it can be supplemented by the second delivery pump 6 and the sixth connecting pipe 62 to meet the needs of the heat exchange device 2.

[0042] Furthermore, a first control valve 611 and a second control valve 621 are provided to control the on-off of the water flow on the fifth connecting pipe 61 and the sixth connecting pipe 62 respectively.

[0051] The first water through hole 411 and the second water through hole 412 are provided to conduct the water flow on the guide plate 41 , thereby preventing the hot water flow from accumulating in the guide plate 41 and affecting the subsequent transportation and guidance of the hot water flow.

[0052] See also Figure 2 In some embodiments, a vent 44 is provided on the side wall of the hot water storage tank 4 , and the vent 44 is disposed below the guide plate 41 and above the liquid level of the hot water storage tank 4 .

[0053] The air outlet 44 is provided so that an air flow channel is formed under the rotation of the fan 33; specifically, the wind flow formed when the fan 33 rotates can pass through the air guide gap between the connecting rods 42 and be discharged through the air outlet 44 on the hot water storage tank 4 to form a first air guide channel.

[0055] By arranging a ventilation duct 45 in the middle of the guide plate 41, a second air guide channel can be conveniently formed between the ventilation duct 45 and the air outlet 44, which promotes the fan 33 to cool the hot water flow in the guide plate 41 and flowing downward from the guide plate 41, thereby improving the cooling effect.

[0057] The first filter screen 46 and the second filter screen 47 are arranged at intervals up and down to collect impurities in the hot water flow, thereby preventing the impurities in the hot water flow from affecting the circulation of the water flow.

[0058] By arranging the first filter screen 46 lower than the outflow end of the second connecting pipe 21 , the first filter screen 46 can intercept impurities starting from the outflow end of the second connecting pipe 21 .

[0059] Optionally, in order to facilitate the collection and processing of impurities on the first filter 46 and the second filter 47, the first filter 46 and the second filter 47 can have a certain slope; optionally, the first filter 46 is set to be inclined downward from the edge of the guide plate 41 toward the direction of the ventilation duct 45, and the second filter 47 is set to be inclined upward from the inner wall of the hot water storage tank 4 toward the direction of the ventilation duct 45.
