Description

Technical Field

[0001] This utility model belongs to the field of cooling technology for thermal power plant equipment, and specifically relates to an auxiliary machine cooling water device. Background Technology

[0002] Auxiliary equipment refers to auxiliary mechanical equipment used to assist the normal operation of the main unit. In power plants, auxiliary equipment mainly includes various conveying mechanisms, coal mills, etc. These auxiliary machines generate a large amount of heat during operation, so they need to be cooled by auxiliary machine cooling water. The cooling water removes the heat generated by eddy current losses, friction losses, etc., during the operation of the auxiliary machines, keeping the temperature of the equipment within a reasonable range and ensuring long-term stable operation.

[0003] If water is used to spray and cool the heat dissipation parts of the auxiliary machine, the actual problem is that the spraying will cause the heat dissipation surface to undergo a wet-dry cycle, which will repeatedly precipitate tiny mineral crystals or generate microbial organic matter particles due to moisture, gradually accumulating into a dense scale layer. Spraying heat dissipation will increase the scale buildup in the heat dissipation parts of the auxiliary machine. Scale buildup will affect the heat transfer of the heat dissipation parts and the workload of descaling and maintenance in the later stage will be large. In addition, water is difficult to recycle when using spraying, which will increase water consumption. Utility Model Content

[0004] This application proposes an auxiliary machine cooling water device that can cool the heat dissipation parts of the auxiliary machine in a non-spray manner, thereby avoiding scaling and improving heat dissipation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary machine cooling water device includes a cooling shroud with air inlets on both sides and an air outlet on the top. A first fan is installed at the air outlet and is connected to a motor. A water tank is installed inside the cooling shroud, and an outlet main pipe and a return main pipe are connected to the bottom of the water tank. An outlet branch pipe is connected to the outlet main pipe, and a return branch pipe is connected to the return main pipe. The outlet branch pipe and the return branch pipe are connected to a cooling assembly. The cooling assembly includes a cooling pipe with multiple thin plates connected in series. The water inlet at the bottom of the cooling pipe is connected to the outlet branch pipe, and the water outlet at the top of the cooling pipe is connected to the return branch pipe. A first pump body is installed on the outlet main pipe.

[0007] In one embodiment of this application, a louvered plate is provided at the air inlet.

[0008] In one embodiment of this application, a fixing frame is provided at the air outlet, and the fixing frame is connected to the edge of the air outlet.

[0009] In one embodiment of this application, the sidewall of the cooling shroud is provided with a groove.

[0010] In one embodiment of this application, an auxiliary cooling box is provided on one side of the cooling shroud. The auxiliary cooling box is connected to the water tank through an inlet auxiliary pipe and a return auxiliary pipe. A second pump body is installed on the inlet auxiliary pipe, and a third pump body is installed on the return auxiliary pipe.

[0011] In one embodiment of this application, a second fan is provided on one side of the sheet.

[0012] In one embodiment of this application, fins are installed on the return water header.

[0013] In summary, the technical solution proposed in this application includes the following beneficial technical effects: the cooling water in the outlet main pipe flows into the cooling pipe through the outlet branch pipe, and makes heat transfer contact with the heat dissipation part of the auxiliary machine through the multi-layer heat dissipation fins set on the cooling pipe. The cooling water temperature rises and flows into the return main pipe through the return branch pipe, and then flows back into the water tank in the cooling cover for cooling. This cycle is repeated, so that the cooling water cools the heat dissipation part of the auxiliary machine in a non-spraying manner during the cooling process, avoiding scaling, improving heat dissipation efficiency, reducing cooling water consumption and saving water resources by recycling the cooling water.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0030] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] This embodiment provides an auxiliary machine cooling water device, see reference. Figures 1-5 As shown, the device includes a cooling shroud 1, with air inlets 11 on both sides and an air outlet 12 on the top. A first fan 2 is installed at the air outlet 12 and is connected to a motor 21. A water tank 3 is installed inside the cooling shroud 1. A main outlet pipe 4 and a main return pipe 5 are installed at the bottom of the water tank 3. A branch outlet pipe 41 is connected to the main outlet pipe 4, and a branch return pipe 51 is connected to the main return pipe 5. The branch outlet pipe 41 and the branch return pipe 51 are connected to a cooling assembly. The cooling assembly includes a cooling pipe 6 with multiple thin plates 61 connected in series. The bottom end of the cooling pipe 6 is connected to the branch outlet pipe 41, and the top end of the cooling pipe 6 is connected to the branch return pipe 51. A first pump body 42 is installed on the main outlet pipe 4.

[0032] In the above embodiment, the auxiliary cooling water device includes a cooling cover 1, a water tank 3 is provided inside the cooling cover 1, the water tank 3 is used to hold cooling water, air inlets 11 are provided on both sides of the cooling cover 1, and an air outlet 12 is provided on the top of the cooling cover 1. A first fan 2 is provided at the air outlet 12. The first fan 2 is connected to a motor 21. The motor 21 drives the first fan 2 to run and discharge the air inside the cooling cover 1, thereby creating a negative pressure inside the cooling cover 1. This allows external air to enter the cooling cover 1 through the air inlets 11 on both sides of the cooling cover 1 and then be discharged through the air outlet 12, so that the air circulates inside the cooling cover 1. The circulated air exchanges heat with the water tank 3, thereby cooling the cooling water in the water tank 3 to a temperature close to the outdoor temperature. The outlet branch pipe 41 and the return branch pipe 51 are respectively connected to the inlet and outlet of the cooling pipe 6 of the cooling assembly. Multiple heat-conducting thin plates 61, such as metal plates 61, are connected in series on the outer wall of the cooling pipe 6. The side of the thin plate 61 is in contact with the heat dissipation part of the auxiliary machine, so that the heat dissipation part of the auxiliary machine exchanges heat with the cooling pipe 6 through the thin plate 61 to achieve cooling of the heat dissipation part of the auxiliary machine. A first pump body 42 is installed on the outlet main pipe 4 to pressurize the cooling water in the outlet main pipe 4. The cooling water flows into the cooling pipe 6 through the outlet branch pipe 41. It makes heat transfer contact with the heat dissipation part of the auxiliary machine through the multi-layer heat dissipation fins 61 set on the cooling pipe 6. The cooling water temperature rises and flows into the return main pipe 5 through the return branch pipe 51. Then it flows back into the water tank 3 in the cooling cover 1 for cooling. This cycle is repeated so that the heat dissipation part of the auxiliary machine is cooled in a non-spraying manner during the cooling process of the cooling water, avoiding scale buildup, improving heat dissipation efficiency, reducing cooling water consumption and saving water resources by recycling the cooling water.

[0033] In one embodiment of this application, see reference Figure 1 As shown, a louvered plate 111 is provided at the air inlet 11.

[0034] In the above embodiment, the louvered plate 111 is provided with multiple ventilation openings to reduce the cross-section through which air flows. On the one hand, this can increase the gas flow rate, and on the other hand, it can prevent the airflow from becoming too turbulent when the gas enters from the air inlet 11, thus guiding the airflow and improving the heat exchange efficiency of the airflow.

[0035] In one embodiment of this application, see [reference] Figure 1 As shown, a fixing frame 121 is provided at the air outlet 12, and the fixing frame 121 is connected to the edge of the air outlet 12.

[0036] In the above embodiment, the fixing bracket 121 is used to fix the motor 21, preventing the motor 21 from shaking due to airflow during operation, which helps to improve the stability of the motor 21 during operation.

[0037] In one embodiment of this application, see reference Figure 1 and Figure 3 As shown, the side wall of the cooling cover 1 is provided with a groove 13.

[0038] In the above embodiment, the groove 13 provided on the side wall of the cooling cover 1 increases the contact area between the side wall and the outside, i.e. the heat exchange area, compared with the plane, which is beneficial to improving the heat dissipation efficiency of the cooling cover 1.

[0039] In one embodiment of this application, see reference Figure 3 As shown, an auxiliary cooling box 7 is provided on one side of the cooling cover 1. The auxiliary cooling box 7 is connected by an inlet auxiliary pipe 71 and a return auxiliary pipe 72. A second pump body 711 is installed on the inlet auxiliary pipe 71, and a third pump body 721 is installed on the return auxiliary pipe 72.

[0040] In the above embodiment, when the cooling water temperature in the water tank 3 is too high and the cooling cover 1 cannot cool the cooling water in the water tank 3 in time, the second pump body 711 can be turned on to inject the cooling water in the auxiliary cooling box 7 into the water tank 3. The third pump body 721 on the return water auxiliary pipe 72 pumps the cooling water in the water tank 3 back into the auxiliary cooling box 7, so that the cooling water in the water tank 3 and the cooling water in the auxiliary cooling box 7 circulate and exchange, thereby achieving the effect of regulating the cooling water temperature in the water tank 3, which is beneficial to improving the cooling water heat exchange efficiency of the cooling water device. In addition, the second pump body 711 and the third pump body 721 have the same drainage volume during operation to maintain the balance of cooling water inflow and outflow in the auxiliary cooling box 7, which is beneficial to improving the stability of the device operation.

[0041] In one embodiment of this application, see reference Figure 5 As shown, a second fan 611 is provided on one side of the thin sheet 61.

[0042] In the above embodiments, when cooling electrical equipment in some enclosed environments, such as control electrical components in the engine room, non-contact cooling is required to prevent leakage and short circuit. The second fan 611 drives the surrounding air to flow through the thin plate 61 on the cooling pipe 6 to generate heat exchange, thereby reducing the temperature of the air around the electrical appliance and thus producing a cooling effect on the electrical appliance, which is beneficial to improving the adaptability and safety of the device cooling.

[0043] In one embodiment of this application, see reference Figure 1 As shown, fins 52 are installed on the return water header 5.

[0044] In the above embodiment, the cooling water in the return water header 5 exchanges heat with the outside during the return process, and the cross-section of the fins 52 is larger than the cross-section of the return water header 5, which increases the heat exchange area and reduces the temperature, thus improving the cooling efficiency of the cooling water device.

[0045] In actual use, the motor 21 drives the first fan 2 to expel air from the cooling shroud 1, creating a negative pressure inside the cooling shroud 1. This allows external air to enter the cooling shroud 1 through the air inlets 11 on both sides and exit through the air outlets 12, causing the air to circulate within the cooling shroud 1. The circulating air exchanges heat with the water tank 3, cooling the water in the water tank 3. Furthermore, a first pump body 42 is installed on the outlet header 4 to pressurize the cooling water in the outlet header 4. The cooling water flows into the cooling pipe 6 through the outlet branch pipe 41, and then through the multi-layer heat dissipation fins 61 on the cooling pipe 6 to make heat transfer contact with the heat dissipation part of the auxiliary machine. The cooling water temperature rises and flows into the return header 5 through the return branch pipe 51, then back into the water tank 3 inside the cooling shroud 1 for cooling. This cycle repeats, achieving non-spray cooling of the heat dissipation part of the auxiliary machine during the cooling process.

[0046] In addition, a one-way valve is installed on the return water branch pipe 51 so that the cooling return water flows into the return water main pipe 5 in one direction through the return water branch pipe 51 to prevent the cooling return water from flowing back, thereby improving the cooling efficiency of the cooling water.

[0047] The shape and length of each pipeline in this application can be arranged according to the actual situation.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
