DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 As shown, a cooling tower includes: a tower body 2, a driving pump 6, a water outlet pipe 4 and a water return pipe 5. The tower body 2 has an inner cavity 9, and the driving pump 6 is connected to the water outlet hole 7 and the water return hole 8 through the water outlet pipe 4 and the water return pipe 5, respectively, to drive the inner cavity 9 to flow out of the inner cavity 9 through the water outlet hole 7, and flow back into the inner cavity 9 through the water return hole 8. The use of such a technical solution can drive the driving pump 6 to drive the water in the inner cavity 9 to flow out and exchange heat with the external environment before flowing back into the inner cavity 9, which can not only save energy but also greatly reduce maintenance costs. In actual applications, the number of inner cavities 9 is at least two, and at this time, the number of water outlet pipes 4 and the water return pipes 5 are also equal to the number of inner cavities 9, and correspond one to one.

[0028] Furthermore, if Figure 1As shown, the heating device 3 is also included. One end of the water outlet pipe 4 is connected to the water outlet hole 7, and the other end is connected to the heating device 3. One end of the water return pipe 5 is connected to the heating device 3, and the other end is connected to the water return hole 8, so that the water in the inner cavity 9 can flow to the heating device 3 through the water outlet pipe 4, and flow back to the inner cavity 9 through the water return pipe 5 after being heated by the heating device 3. With such a technical solution, the water in the inner cavity 9 can be heated by the heating device 3. In actual work, Figure 1 As shown, the inner cavity 9 is provided with a water receiving tray 1, so that the purpose of heating the water receiving tray 1 is achieved, thereby preventing the water receiving tray 1 from freezing. Compared with the prior art, it not only has lower energy consumption, but also can greatly save maintenance costs. It should be noted that at this time, the driving pump 6 can drive the water in the inner cavity 9 to circulate between the inner cavity 9 and the heating device 3. When the number of the inner cavities 9 is at least two, the number of the water receiving trays 1 is equal to the number of the inner cavities 9, and they correspond one to one.

[0029] Specifically, Figure 1 As shown, the heating device 3 includes a heating device 10, a first heat medium pipe 11, a second heat medium pipe 12 and a heat exchanger 13. The heat exchanger 13 has a heat medium channel (not shown) and a water circulation channel (not shown). The heat medium channel forms a heat medium inlet 14 and a heat medium outlet 15 on the surface of the heat exchanger 13. One end of the first heat medium pipe 11 is connected to the heating device 10, and the other end is connected to the heat medium inlet 14. One end of the second heat medium pipe 12 is connected to the heating device 10, and the other end is connected to the heat medium outlet 15, so that the heat medium heated by the heating device 10 can enter the heat medium channel through the first heat medium pipe 11, and flow back to the heating device 10 through the second heat medium pipe 12 after flowing through the heat medium channel. The water circulation channel forms a circulating water inlet 16 and a circulating water outlet 14 on the surface of the heat exchanger 13, the outlet pipe 4 is connected to the circulating water inlet 16, and the return pipe 5 is connected to the circulating water outlet 14, so that the water in the inner cavity 9 can flow through the water circulation channel, and after heat exchange with the heat medium flowing through the heat medium channel, flow back to the inner cavity 9. In this way, the water flowing through the water circulation channel can be heated by the heat medium flowing through the heat medium channel. In actual production, the heating device 10 can be an air conditioner, but is not limited to this, and can also be any other device that can achieve the purpose of the invention.

[0030] Specifically, the water outlet 7 is a sewage discharge hole of the inner cavity 9. Figure 1 As shown, it also includes a drain pipe 18, a first valve 19 and a second valve 20. One end of the drain pipe 18 is connected to the water outlet pipe 4, and the other end can be connected to an external target position. The first valve 19 is arranged on the drain pipe 18, and the second valve 20 is arranged on the water outlet pipe 4 and is located between the heating device 3 and the connection position between the drain pipe 18 and the water outlet pipe 4. In this way, the flow direction of water flowing out of the water outlet hole 7 can be controlled by the first valve 19 and the second valve 20.

[0031] As an implementation method, Figure 1 As shown in , a temperature acquisition device 21 is provided in the inner cavity 9. The temperature acquisition device 21 is electrically connected to the first valve 19 and the second valve 20. The temperature acquisition device 21 acquires the temperature information of the water in the inner cavity 9 in real time, and controls the operation of the first valve 19 and / or the second valve 20 according to the information. For example, when the temperature acquisition device 21 acquires the temperature of the water in the inner cavity 9 to be lower than a certain value, the first valve 19 can be controlled to be closed, and the second valve 20 can be controlled to be opened. At this time, the water flowing out of the water outlet 7 will not flow from the sewage pipe 18 to the external target position, but can only flow to the heating device 3 for heating and then flow back to the inner cavity 9. Specifically, the number of temperature acquisition devices 21 is equal to the number of inner cavities 9, and they correspond one to one.

[0032] As an implementation method, Figure 1 As shown in the figure, a heating element 22 is provided in the inner cavity 9 to heat the water in the inner cavity 9. The heating element 22 may be an electric heating element. When a temperature acquisition device 21 is provided in the inner cavity 9, the temperature acquisition device 21 is electrically connected to the heating element 22, and the temperature acquisition device 21 acquires the temperature information of the water in the inner cavity 9 in real time, and controls the heating element 22 to work according to the information. For example, when the temperature acquisition device 21 acquires that the temperature of the water in the inner cavity 9 is lower than a certain value, the heating element 22 may be controlled to work so as to heat the water in the inner cavity 9. Specifically, the number of the heating elements 22 is equal to the number of the inner cavities 9, and they correspond one to one.

[0033] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
