[0002] Currently, hydraulic modules can be used as external power sources for centralized heating and cooling systems. They generally include water pumps, expansion tanks, and control modules. However, existing expansion tanks are usually located on top of the pipes and placed separately, while water pumps are generally fixed to the ground or on a bracket. The control module is placed in a separate electrical control cabinet. The expansion tank needs to be connected to the water pump's outlet or inlet / outlet pipes through pipes, and the electrical control cabinet needs to be connected to the water pump or other external electrical components through connecting cables. Due to the separate placement of these components, they need to be connected through external pipes and connecting cables. However, these pipes and connecting cables are easily interfered with and affected by external devices, increasing the difficulty of engineering installation. They also make the connecting pipes or connecting cables between various components messy and disorganized, resulting in an unreasonable layout that is not only inconvenient for installation but also for maintenance.

[0003] Therefore, existing technologies still need to be improved and developed. Utility Model Content

The expansion tank 5 and the first water pump 14 are both located on the side near the first detachable side door 12. A control component 6 is also installed inside the housing 1. The control component 6 is located on the side near the switch door 11.

[0040] Specifically, by arranging the first water pump 14, inlet pipe 3, outlet pipe 4, expansion tank 5, and control component 6 within a single enclosure 1, not only is the space occupied by the hydraulic module reduced, but installation and maintenance efficiency is also improved. Furthermore, the hydraulic module has a reasonable layout and a small structure, and the integration of multiple components into a single module facilitates transportation and subsequent management. The control component 6, an electrical component, is located near the switch door 11 for easy control and maintenance. The first detachable side door 12 is connected to the enclosure 1 by bolts. The first water pump 14 is mounted on the bottom wall inside the enclosure 1, and a bracket is located on the side of the enclosure 1 near the first detachable side door 12. The expansion tank 5 is mounted on the bracket. Removing the first detachable side door 12 facilitates the replacement and maintenance of the first water pump 14 and the expansion tank 5.

[0041] In this embodiment, as shown in the appendix Figure 5 As shown, both the inlet pipe 3 and the outlet pipe 4 are fixed in the through hole by flanges; specifically, two semi-circular plates are provided at the through hole position, and the two semi-circular plates cooperate to wrap the inlet pipe 3 and the outlet pipe 4, thereby facilitating the installation of the flanges to fix the inlet pipe 3 and the outlet pipe 4.

[0042] One embodiment of this application is shown in the appendix. Figure 3As shown, the hydraulic module also includes a second detachable side door 13, a second water pump 15, an inlet tee 31, and an outlet tee 41. A second detachable side door 13 is located on the side of the housing 1 opposite to the first detachable side door 12. The second detachable side door 13 is fixed to the housing 1 with bolts. The first detachable side door 12 and the second detachable side door 13 are arranged symmetrically. A second water pump 15 is also located at the bottom inside the housing 1, near the second detachable side door 13. Removing the second detachable side door 13 facilitates the installation and maintenance of the second water pump 15. The inlet pipe 3 is located within the housing. One end of the housing 1 is provided with an inlet tee 31, and the other two ends of the inlet tee 31 are respectively connected to a first pipe 32 and a second pipe 33. The ends of the first pipe 32 and the second pipe 33 away from the inlet tee 31 are respectively connected to the inlet of the first water pump 14 and the inlet of the second water pump 15. The outlet pipe 4 is provided with an outlet tee 41 at one end of the housing 1, and the other two ends of the outlet tee 41 are connected to a third pipe 42 and a fourth pipe 43. The ends of the third pipe 42 and the fourth pipe 43 away from the outlet tee 41 are respectively connected to the outlet of the first water pump 14 and the outlet of the second water pump 15.

[0043] By setting up inlet tee 31 and outlet tee 41, both inlet pipe 3 and outlet pipe 4 can be connected to the first water pump 14 and the second water pump 15. Switch valves are installed in the first pipe 32, the second pipe 33, the third pipe 42, and the fourth pipe 43. Through the setting of the switch valves, one water pump can be driven individually or two water pumps can be driven simultaneously. The second water pump 15 can be used as a backup water pump to start working when the first water pump 14 fails, so as to ensure the smooth operation of the hydraulic module. At the same time, by placing the first water pump 14 and the second water pump 15 side by side, together with the inlet tee 31 and the outlet tee 41, the pipeline connection is neat and orderly, which facilitates installation and maintenance.

[0044] In this embodiment, both the first detachable side door 12 and the second detachable side door 13 are provided with lifting grooves on opposite sides to facilitate installation and disassembly.

[0045] In this embodiment, as shown in the appendix Figure 1 and attached Figure 4 As shown, both the first pipe 32 and the second pipe 33 have connection ports in their vertical sections. A filter 8 is installed at the connection port. The filter 8 forms a certain angle with the vertical first pipe 32 or the second pipe 33, and a drain valve is installed at the bottom of the filter 8. The filter 8 can be used to filter the liquid in the first pipe 32 and the second pipe 33, and the liquid can be discharged through the drain valve.

[0046] Furthermore, the two filters 8 are respectively facing the first removable side door 12 and the second removable side door 13. By disassembling the first removable side door 12 and the second removable side door 13, the two filters 8 can be easily operated.

[0047] In this embodiment, as shown in the appendix Figure 4 As shown, the first pipe 32, the second pipe 33, the third pipe 42 and the fourth pipe 43 are all equipped with manual valves 9, which can be manually closed. At the same time, the third pipe 42 and the fourth pipe 43 are also equipped with check valves 44, which are located at the bottom of the manual valves 9, to prevent the flow from being diverted by the other water pump when one water pump is running.

[0048] In this embodiment, an air vent valve 2 is provided on the water outlet pipe 4, and the air vent valve 2 is located at the highest point of the pipe to discharge the gas in the water outlet pipe 4, so as to ensure the pressure stability of the water outlet pipe 4 and the stability of the entire system.

[0049] In this embodiment, an electrical control box 7 is provided inside the housing 1 on the side near the switch door 11. The top and sides of the electrical control box 7 are fixed to the frame inside the housing 1 by bolts. The electrical control box 7 is arranged opposite to the switch door 11, and an installation groove is provided on the side of the electrical control box 7 near the switch door 11. The installation groove is used to install the control components 6. The control components 6 are all electrical components, including a motor controller, wiring terminals and a power switch.

[0050] In this embodiment, as shown in the appendix Figure 3 As shown, the first detachable side door 12 has multiple air inlets 121 on the side away from the electrical control box 7, and the second detachable side door 13 has multiple air outlets 131 on the side closer to the electrical control box 7. The electrical control box 7 has multiple exhaust fans 16 on the side closer to the second detachable side door 13. The multiple exhaust fans 16 are arranged vertically and correspond to the air outlets 131. By activating the exhaust fans 16, air can enter through the air inlets 121, and the heat is carried away by the components inside the box 1 and discharged through the air outlets 131, thus achieving the function of heat dissipation.

[0051] Furthermore, the air outlet 131 and the air inlet 121 are located at opposite corners on both sides of the housing 1, so that the air that can pass through the air inlet 121 passes through the internal components of the housing 1 and undergoes heat exchange before being discharged through the air outlet 131; at the same time, the exhaust fan 16 is located on the back of the electrical control box 7 away from the control component 6, which can also dissipate heat from the electrical control box 7 and ensure that the temperature of the control component 6 does not get too high.

[0052] Further details are attached. Figure 5As shown, the electrical control box 7 is provided with an air duct 17, which is located on the side of the exhaust fan 16 away from the second detachable side door 13. The air duct 17 is provided with a heat dissipation plate, which is connected to the side wall of the electrical control box 7, so as to further dissipate heat from the control component 6.

[0053] Furthermore, louvers 18 are provided on the outer side of both the air outlet 131 and the air inlet 121. The louvers 18 are arc-shaped grooves. The louvers 18 cooperate with the first detachable side door 12 and the second detachable side door 13, and form a downward-facing channel on the outer side of the air outlet 131 and the air inlet 121. The louvers 18 can block the air outlet 131 and the air inlet 121, thereby effectively preventing rainwater from entering the air outlet 131 or the air inlet 121 at an angle.

[0054] In this embodiment, two mounting holes are provided on the side of the housing 1 away from the switch door 11. Mechanical pressure gauges 19 are respectively installed in the two mounting holes. The two mechanical pressure gauges 19 are respectively connected to the water inlet pipe 3 and the water outlet pipe 4 located in the housing 1 through pipes, and are used to display the liquid pressure in the water inlet pipe 4 and the water outlet pipe 3.

[0055] In this embodiment, a cover plate is provided on the top of the box 1, and the side wall of the cover plate is provided with a folded edge. Adjacent folded edges are welded and sealed. By providing folded edges on the side wall of the cover plate, a groove is formed at the bottom of the cover plate, so that the cover plate can be snapped onto the top of the box 1. At the same time, the surface of the cover plate is flat, which can effectively prevent rainwater from entering the box 1. The folded edges of the cover plate are connected to the box 1 by bolts.

[0056] In this embodiment, a temperature sensor and a pressure sensor are also provided on the inlet pipe 3 and the outlet pipe 4; a safety valve is also provided at the end of the inlet pipe 3 and the outlet pipe 4 away from the first water pump 14.
