DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions 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 direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] Example:

[0031] Reference Figure 1-Figure 6 The embodiment of the utility model provides a water-cooling energy-saving device, including a refrigeration unit and a heat exchange unit, the refrigeration unit is used to cool down the water, the heat exchange unit is used to cool down the low-temperature water to the equipment that needs heat dissipation and cooling, and also includes a liquid storage tank 1 for storing water, the liquid storage tank 1 is cylindrical in shape, and the upper and lower inner walls of the liquid storage tank 1 are provided with a thermal insulation layer, and the liquid storage tank 1 is provided with two cavities, one of which surrounds the other cavity, that is, one of the cavities will surround the other cavity, and the cavity located inside is used to store cold water; wherein, the output end of the refrigeration unit and the heat exchange unit is connected to one of the cavities, and the input end of the refrigeration unit and the heat exchange unit is connected to the other cavity, and one of the cavities is provided with an isolation part for isolating the air between the two cavities.

[0032] Specifically, at night, the refrigeration unit draws warm water from the cavity, and stores the low-temperature water in another cavity after cooling the warm water; during the day, the heat exchange unit draws cold water to cool the external heating equipment, and the warm water after heat exchange is stored in the cavity originally storing warm water. During the heat exchange period during the day, the airflow in the warm water cavity will enter the cold water cavity. At this time, the isolation part can prevent the hot air of the warm water from directly contacting the cold water, making it difficult for the cold water to heat up quickly, and the warm water can complete the heat dissipation through the outer wall of the liquid storage tank 1, reducing the power consumption required for cooling at night; and at night, when the cold water cavity is filled and the warm water cavity is completely empty, the warm water cavity can separate the cold water cavity from the outside air, thereby achieving the effect of heat preservation. In summary, under the premise of ensuring water storage, the use of the floor space occupied by the water storage equipment can be reduced, and at the same time, the cold water can be isolated and insulated by the warm water cavity, making the water storage equipment more efficient and energy-saving.

[0033] The two cavities in the water-cooling energy-saving device include an inner cavity 4 and an outer cavity 5. The inner cavity 4 is used to store cold water, and the outer cavity 5 is used to store warm water. A cylindrical tube 2 is fixedly connected to the bottom of the liquid storage tank 1. An insulation layer is provided on the inner wall of the cylindrical tube 2. The axis of the cylindrical tube 2 is collinear with the axis of the liquid storage tank 1. An airflow gap 3 is provided between the top of the cylindrical tube 2 and the inner top of the liquid storage tank 1. The inner cavity 4 is formed by the cylindrical tube 2 and the bottom of the liquid storage tank 1, and the outer wall of the cylindrical tube 2 and the inner wall of the liquid storage tank 1 form an outer cavity 5.

[0034] Specifically, when the water in the outer cavity 5 is cooled and passed into the inner cavity 4, the excess air in the inner cavity 4 will enter the outer cavity 5 through the air flow gap 3, and the outer cavity 5 will be filled with air, so that the cold water in the inner cavity 4 is not easy to heat up, and the energy-saving effect is better. On the contrary, when the water in the inner cavity 4 is used and transported to the outer cavity 5, the air in the outer cavity 5 will enter the inner cavity 4 through the air flow gap 3, so the air in the inner cavity 4 and the outer cavity 5 will circulate with each other and be isolated from each other by the isolation part, thereby preventing bacteria and dust in the outside air from contaminating the water and improving the service life of the water.

[0035] The isolation part in the water-cooling energy-saving device includes a suspension plate 6 longitudinally slidably connected to the inner wall of the inner cavity 4, and at least one fine hole 7 is provided on the suspension plate 6. The diameter of the fine hole 7 is 1 mm, and the number of fine holes 7 is between 100 and 500. The preferred number in this application is 400.

[0036] Specifically, when the air in the outer cavity 5 enters the inner cavity 4, if cold water is stored in the inner cavity 4, the cold water will make the suspension board 6 always float on the water surface, and the suspension board 6 can isolate the air from the outer cavity 5 entering the inner cavity 4. Although both air and water can pass through the pores 7, when the suspension board 6 floats on the water surface, the water surface will block the lower end of the pores 7, and the hot air at the upper end cannot enter the lower end of the suspension board 6, thereby achieving the effect of isolation, while water can flow from the upper end of the pores 7 to the lower end.

[0037] The refrigeration unit in the water-cooled energy-saving device includes a first water pump 13 fixedly mounted on the outer wall of the liquid storage tank 1, the output end of the first water pump 13 is fixedly connected to a first drainage pipe 12 extending to the top of the inner cavity 4, and the input end of the first water pump 13 is fixedly connected to a first water inlet pipe 14 extending to the bottom of the outer cavity 5; wherein a first heat exchanger 15 is mounted in the middle of the first drainage pipe 12, a refrigerator 16 is fixedly mounted on the outer wall of the liquid storage tank 1, and the output end of the refrigerator 16 faces the first heat exchanger 15;

[0038] Specifically, when the warm water needs to be cooled, the first water pump 13 will draw the warm water in the outer cavity 5 through the first water inlet pipe 14 and input it into the first heat exchanger 15. At this time, the cold air will be blown to the first heat exchanger 15 through the refrigerator 16 to cool the warm water passing through the first heat exchanger 15. The cooled cold water will be discharged into the inner cavity 4 through the first drain pipe 12.

[0039] The heat exchange part in the water-cooling energy-saving device includes a second water pump 17 fixedly installed on the outer wall of the liquid storage tank 1, the input end of the second water pump 17 is fixedly connected to a second liquid inlet pipe 20 extending to the bottom of the inner cavity 4, and the output end of the second water pump 17 is fixedly connected to a second drain pipe 18 extending to the top of the outer cavity 5, and a second heat exchanger 19 is installed in the middle of the second drain pipe 18.

[0040] Specifically, when cold water is needed to cool down external equipment or air-conditioning equipment, the heat dissipation surface of the external equipment is attached to the second heat exchanger 19. At this time, the cold water in the inner cavity 4 is extracted by the second water pump 17, passed through the second heat exchanger 19, and then discharged back to the inner cavity 4. When the cold water passes through the second heat exchanger 19, the heat dissipation work of the second heat exchanger 19 can be completed, and the second heat exchanger 19 will complete the heat dissipation work of the external equipment or air conditioning.

[0041] A U-shaped tube 10 is provided in the inner cavity 4 and the outer cavity 5, and a nozzle 11 facing the inner wall of the inner cavity 4 and the outer cavity 5 is installed on the outer wall of the U-shaped tube 10. A driving part is provided on the liquid storage tank 1 to drive the U-shaped tube 10 to continuously circle in the inner cavity 4 and the outer cavity 5. The driving part includes a rotating tube 8 rotatably connected to the top of the liquid storage tank 1, and the lower end of the rotating tube 8 extends into the liquid storage tank 1. A transverse tube 9 is fixedly connected to the outer wall of the liquid storage tank 1, and the U-shaped tube 10 is fixedly connected to the transverse tube 9 and is communicated with the transverse tube 9; wherein, a motor 21 is fixedly installed on the liquid storage tank 1, and a gear 22 is fixedly installed on the output shaft of the motor 21 and the rotating tube 8, and the two gears 22 are meshingly connected.

[0042] Specifically, when it is necessary to clean the inner walls of the inner cavity 4 and the outer cavity 5, the cleaning liquid is passed into the rotating tube 8, the cleaning liquid will enter the transverse tube 9 through the rotating tube 8, and then enter the U-shaped tube 10, and finally will be sprayed from the nozzle 11 to the inner walls of the inner cavity 4 and the outer cavity 5. At this time, the motor 21 is started, and the motor 21 will drive the rotating tube 8 to rotate through two mutually meshing gears 22. The rotating tube 8 will drive the U-shaped tube 10 to surround the inner cavity 4 and the outer cavity 5 through the transverse tube 9, and the U-shaped tube 10 will fully and efficiently flush the inner walls of the inner cavity 4 and the outer cavity 5 through the nozzle 11. Compared with the two storage tanks, cleaning and maintenance are more convenient and efficient.

[0043] The end of the first drain pipe 12 passes through the rotating pipe 8 and is colinear with the axis of the rotating pipe 8 , so as to avoid interference between the transverse pipe 9 and the first drain pipe 12 when the rotating pipe 8 drives the transverse pipe 9 to rotate.

[0044] An end cover 23 is fixedly connected to the first drain pipe 12, the upper end of the rotating pipe 8 is rotatably connected to the lower port of the end cover 23, and an infusion tube 24 is fixedly connected to the end cover 23. When cleaning liquid needs to be transported into the rotating pipe 8, the cleaning liquid is transported to the infusion tube 24, and the infusion tube 24 transports the cleaning liquid to the rotating pipe 8 through the end cover 23.

[0045] A sewage pipe 25 connected to the inner cavity 4 and the outer cavity 5 is fixed at the lower end of the liquid storage tank 1. A valve is also installed in the sewage pipe 25. When cleaning the inner cavity 4 and the outer cavity 5, sewage can be easily discharged through the sewage pipe 25.
