[0002] Industrial equipment requires cooling during production and operation, and cooling water is the most common cooling medium. A single piece of equipment often has multiple units that need to be cooled.

[0003] Chinese patent CN 221886751U discloses a sensor cooling water distribution device, including a bracket. An inlet pipe is fixed to the bottom of the bracket, and a return pipe is arranged above the inlet pipe within the bracket. Each inlet and outlet of the return pipe is connected to a branch pipe. A temperature sensor is fixed to the top of each branch pipe, and a rotor flow meter is installed directly below the temperature sensor on each branch pipe. A ball valve is installed on the branch pipe above the return pipe, and a rubber hose connects the ball valve to the branch pipe. A digital flow sensor is fixed to the outlet side of each branch pipe. A butterfly valve is also installed at the ports of both the inlet and return pipes. Here, the temperature sensor, rotor flow meter, and flow sensor can only be used for detection, while the butterfly valve can only control the on / off state of the pipes and cannot precisely regulate the flow rate.

[0004] To avoid the above problems, it is necessary to provide a new centralized cooling water distribution device to improve the accuracy of flow regulation. Utility Model Content

[0005] The main purpose of this invention is to provide a centralized cooling water distribution device that can improve the accuracy of flow regulation.

[0006] The present invention achieves the above objective through the following technical solution: a centralized cooling water distribution device, comprising an inlet water assembly and a return water assembly, wherein the inlet water assembly comprises a main inlet water pipe and a plurality of inlet water branch pipes connected in parallel to the main inlet water pipe, and the return water assembly comprises a main return water pipe and a plurality of return water branch pipes connected in parallel to the main return water pipe, wherein the number of inlet water branch pipes is equal to the number of return water branch pipes; Each inlet branch pipe is equipped with a flow regulating valve, and each return branch pipe is equipped with a temperature sensor and a flow sensor. The temperature sensor is used to detect the return water temperature of the cooling water, and the flow sensor is used to detect the flow rate of the branch.

[0009] Furthermore, each inlet branch pipe is equipped with an inlet ball valve, and each return branch pipe is equipped with a return ball valve.

[0010] Furthermore, the support also includes several upper connecting rods, which pass through the upper beam along the wide side of the bottom frame. The return water branch pipe is G-shaped and includes a first horizontal section, a downflow section, a second horizontal section, and a riser section connected in sequence. The temperature sensor, the flow sensor, and the return water ball valve are all located on the downflow section and on the same side of the support as the inlet ball valve.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] Example: like Figure 1 and Figure 2 As shown, the cooling water centralized distribution device of this utility model includes an inlet water assembly 1, a return water assembly 2, and a support 3.

[0018] The inlet water assembly 1 provides cooling water and distributes it to various devices or locations within the cooling system. The return water assembly 2 receives the return cooling water from these devices or locations and sends it for centralized processing. The bracket 3 is used to mount and fix the inlet water assembly 1 and the return water assembly 2, allowing the various sensing and control components to be arranged together for easy operation.

[0019] like Figure 1 and Figure 2 As shown, the water inlet assembly 1 includes a main water inlet pipe 11 and multiple water inlet branch pipes 12 connected in parallel to the main water inlet pipe 11. The water return assembly 2 includes a main water return pipe 21 and multiple water return branch pipes 22 connected in parallel to the main water return pipe 21. The number of water inlet branch pipes 12 is equal to the number of water return branch pipes 22.

[0020] Cooling water enters from the main inlet pipe 11, is distributed through inlet branch pipes 12, and then supplied to return branch pipes 22. Each return branch pipe 22 delivers water to one piece of equipment within the water supply system. Used cooling water is collected in the main return pipe 21 via the return branch pipes 22. Since each inlet branch pipe 12 and return branch pipe 22 forms a group, their numbers are identical. Because the water consumption of each piece of equipment varies, the diameter of the different inlet branch pipes 12 can differ, while the diameter of the return branch pipe 22 is generally the same as that of its corresponding inlet branch pipe 12.

[0021] like Figures 1 to 3As shown, each inlet branch pipe 12 is equipped with an inlet ball valve 121 and a flow regulating valve 122, and each return branch pipe 22 is equipped with a temperature sensor 221, a flow sensor 222 and a return ball valve 223.

[0022] Both the inlet ball valve 121 and the return ball valve 223 can be used to manually switch the cooling water circuit on and off. They are opened when the equipment is working and closed when the equipment is not working or encounters a problem. Temperature sensor 221 detects the return water temperature of a specific cooling water circuit, while flow sensor 222 detects the flow rate of that circuit. The temperature and flow rates are transmitted to the control cabinet of the device (not shown), which then controls the opening of the corresponding flow regulating valve 122. Because the heat generated in the equipment can change dynamically, the opening of the flow regulating valve 122 needs to be adjusted accordingly. If the water temperature sensed by temperature sensor 221 exceeds the safe range, the opening of flow regulating valve 122 needs to be increased to accelerate heat exchange efficiency with a larger flow rate; if flow sensor 222 detects that the flow rate is too high, the opening of flow regulating valve 122 needs to be decreased to ensure that the device operates under safe conditions.

[0023] like Figure 1 and Figure 2 As shown, the main water inlet pipe 11 is equipped with an inlet water temperature sensor 111 and a water pressure gauge 112.

[0024] The inlet water temperature sensor 111 can sense the temperature of the inlet water in real time, thereby controlling the initial temperature of the cooling water. If the inlet water temperature is too high, it will not have a cooling effect. In this case, the flow regulating valve 122 can be automatically closed or the inlet ball valve 121 can be manually closed. The water pressure gauge 112 can detect whether the inlet water pressure is within a reasonable range. If the pressure is abnormal, the inlet ball valve 121 or the return ball valve 223 can be manually closed.

[0025] like Figure 1 and Figure 3 As shown, the support frame 3 includes a base frame 31, two support columns 32, an upper beam 33a, a lower beam 33b, several upper connecting rods 34a, several lower connecting rods 34b, and two pairs of reinforcing plates 35. The base frame 31 has a rectangular structure. The lower ends of the two support columns 32 are connected to the middle of the two wide sides of the base frame 31. The reinforcing plates 35 are supported on the inner side of the corner between the support columns 32 and the base frame 31. The upper beam 33a is connected between the upper parts of the two support columns 32, and the lower beam 33b is connected between the lower parts of the two support columns 32. Both the upper beam 33a and the lower beam 33b are along the long side of the base frame 31. The cross-section of the support columns 32 has a U-shaped structure. The main inlet pipe 11 and the main return pipe 21 are connected at the same height to the opposite sides of the middle of the two support columns 32.

[0026] This type of support 3 has good structural strength. The two supporting columns 32, the upper beam 33a, and the lower beam 33b form a ladder-shaped structure in the vertical direction. The reinforcing plate 35 ensures that the ladder-shaped structure is perpendicular to the plane of the bottom frame 31. The load on both sides of the main inlet pipe 11 and the main return pipe 21 is basically equal, reducing the risk of tipping over.

[0027] like Figure 1 and Figure 3 As shown, the upper connecting rod 34a passes through the upper beam 33a along the wide side of the bottom frame 31. The water inlet branch pipes 12 all extend from the lower part of the main water inlet pipe 11. The lower connecting rod 34b passes through the lower beam 33b along the wide side of the bottom frame 31. The return water branch pipe 22 is G-shaped and includes a first horizontal section, a downflow section, a second horizontal section, and a rising section connected in sequence. The temperature sensor 221, the flow sensor 222, and the return water ball valve 223 are all located on the downflow section and on the same side of the bracket 3 as the water inlet ball valve 121. The first horizontal section is connected to the main return water pipe 21. The two ends of the upper connecting rod 34a are respectively connected to the upper side wall of the downflow section and the upper side wall of the rising section. The two ends of the lower connecting rod 34b are respectively connected to the lower side wall of the rising section and the lower side wall of the water inlet branch pipe 12.

[0028] By adopting the above arrangement, all operable positions of the device are exposed on the same side when placed against the wall. The return water branch pipe 22 has slightly more parts than the inlet water branch pipe 12. To reduce fatigue during maintenance, the return water branch pipe 22 is positioned above the inlet water branch pipe 12. The upper connecting rod 34a connects the part of the return water branch pipe 22 that is not directly connected to the main return water pipe 21, thus preventing the return water branch pipe 22 from falling off when disassembling or assembling the temperature sensor 221, flow sensor 222, or return water ball valve 223. The lower connecting rod 34b connects the part of the inlet water branch pipe 12 that is not directly connected to the main inlet water pipe 11, thus preventing the inlet water branch pipe 12 from falling off when disassembling or assembling the inlet water ball valve 121 and flow regulating valve 122.

[0029] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
