Description

Technical Field

[0001] This invention relates to a highly stable integrated cold source container system. Background Technology

[0002] Integrated cold source modules are container-style design and modular architecture-based cooling capacity control and distribution centers. They support multi-compartment parallel operation and flexible capacity expansion, and can be customized in system configuration and function combination according to customer needs to achieve reliable distribution and rapid deployment. They are widely used in centralized cooling scenarios for data centers, industrial plants, and commercial buildings. The hydraulic module is the core distribution unit of the cold source system, integrating water pumps, plate heat exchangers, filters, pressure stabilization, and intelligent control into a standardized distribution system.

[0003] These types of cold source cabins are mostly installed on the roofs of buildings, thus imposing strict limits on the overall weight of the system and requiring lightweight design. Meanwhile, the water pumps and motors in the hydraulic modules, as core vibration sources, generate large-amplitude, wide-bandwidth vibrations during operation, especially during switching of operating conditions. This vibration not only reduces the operational stability of the cold source cabin and accelerates component fatigue damage, but also generates solid-borne noise transmitted through the building structure, and may even affect the piping sealing and operational reliability of the refrigeration system's control components.

[0004] In existing technologies, two common solutions are used to address vibration issues: one is to increase the overall weight of the cold source container and rigidly fix the vibrating components to the container, using its own weight to suppress vibration. However, this solution directly conflicts with the lightweight requirements of roof installation and cannot meet the roof load limit requirements. The other solution is to use a truss-type base with ordinary rubber vibration isolation pads. Although this solution can achieve some weight reduction, the damping performance of the rubber vibration isolation pads is limited, and it cannot effectively dissipate broadband vibration energy. Furthermore, the truss structure has insufficient vibration stability and is prone to structural loosening and fatigue failure under long-term alternating vibration loads. At the same time, it cannot solve the problem of vibration transmission to the control room, making it difficult to meet the dual requirements of lightweight and high stability.

[0005] In addition, existing vibration reduction structures generally suffer from unreasonable force paths. Vibration reduction components are mostly subjected to bending forces, which prevents the full utilization of material mechanical properties. Under long-term operation, they are prone to deformation, fracture and other failures, which further reduces the operational stability and service life of the cold source container system. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned deficiencies in the prior art by providing a highly stable integrated cold source container system, which solves the problems in the prior art where cold source containers cannot simultaneously achieve lightweight design and high vibration resistance, where the vibration reduction structure is subjected to unreasonable stress, where vibration energy cannot be effectively dissipated, and where vibration transmission affects system reliability.

[0007] A highly stable integrated cold source container system includes an outer frame, with an end inspection door at the end of the outer frame, and the interior of the outer frame is divided into a water pump compartment and a control compartment by vibration isolation baffles.

[0008] The pump compartment is equipped with several sets of parallel hydraulic modules. Each hydraulic module includes a pump and a motor. The pump and motor are coaxially connected to form the vibrating component of the hydraulic module.

[0009] The vibration component is supported by an anti-vibration support assembly, which includes a support bracket, a left support, a right support, an anti-vibration base, and an upper cover plate.

[0010] The vibration component is rigidly fixed to the upper surface of the support bracket. The cross-section of the support bracket is U-shaped, and the bottom ends of the support bracket are fixedly connected to the upper surfaces of the left and right supports, respectively.

[0011] The upper cover plate covers the top of the vibration-damping base, and an installation chamber is formed between the upper cover plate and the vibration-damping base; the upper cover plate is provided with limiting grooves that correspond to and match the left support and the right support;

[0012] The mounting chamber is provided with several arc-shaped connectors. The two ends of the arc-shaped connectors are connected to the lower surfaces of the left and right supports, respectively, and the middle part of the arc-shaped connectors is connected to the top of the hydraulic support base. The bottom of the hydraulic support base is connected to the bottom surface of the inner wall of the vibration-damping base through the lower mounting plate.

[0013] The inner wall bottom surface of the vibration-damping base is provided with several hydraulic guide support columns. The hydraulic guide support columns and arc-shaped connecting parts are arranged at intervals. The top of the piston rod of the hydraulic guide support column is connected to the lower surface of the left or right support. The oil chamber of the hydraulic guide support column and the oil chamber of the hydraulic support base are connected in a closed loop through a connecting oil circuit. A damping throttle valve and an energy storage tank are connected in series on the connecting oil circuit.

[0014] Furthermore, the flanges on both sides of the U-shaped structure of the support bracket extend outward, and several reinforcing ribs are provided in the middle of the support bracket. The reinforcing ribs can significantly improve the structural stiffness and bending resistance of the support bracket, effectively disperse vibration loads, avoid local stress concentration, and ensure long-term stable load bearing of the water pump and motor.

[0015] Furthermore, each hydraulic module is equipped with an independent vibration-damping support assembly, and the hydraulic systems of each assembly are independent of each other. This enables vibration reduction decoupling between hydraulic modules, prevents mutual interference between groups, improves the overall vibration reduction stability of the system, and facilitates independent inspection and maintenance of individual modules.

[0016] Furthermore, the hydraulic guide support column is a single-acting hydraulic cylinder, and the rodless chamber of the hydraulic guide support column and the rodless chamber of the hydraulic support seat are connected in a closed loop via a connecting oil circuit; the damping throttle valve is a bidirectional adjustable flow valve used to adjust the damping coefficient of the hydraulic system. This forms a stable closed-loop hydraulic vibration reduction circuit, precisely controlling the system damping, adapting to the wide-frequency vibration suppression requirements under different working conditions, and improving the vibration reduction adaptive capability.

[0017] Furthermore, the preset inflation pressure of the energy storage tank matches the static working pressure of the hydraulic system, and the volume of the energy storage tank is not less than 5% of the total oil volume of the hydraulic system. Increasing the inflation volume can stabilize the oil pressure of the hydraulic system, buffer pressure fluctuations, absorb instantaneous vibration impacts, and ensure the continuous and stable operation of the hydraulic vibration damping system.

[0018] Furthermore, the outer frame adopts a truss frame structure welded from high-strength aluminum alloy profiles, with crisscrossing reinforcing ribs on the inner wall. This structure can achieve significant weight reduction while ensuring the overall rigidity and vibration resistance of the shelter, strictly meeting the roof installation load requirements, and improving the fatigue life of the structure.

[0019] Furthermore, the control cabin is equipped with an integrated control cabinet and an electrical cabinet, and the side wall of the outer frame has inlet and outlet water interfaces corresponding to the hydraulic module. This structure enables the integrated layout of the system control and electrical components, simplifies on-site pipeline connections and installation deployment, and improves system integration and ease of operation and maintenance.

[0020] Furthermore, a self-lubricating wear-resistant coating is provided between the side walls of the left and right supports and the inner wall of the limiting slide groove. The self-lubricating wear-resistant coating is graphite. Through the graphite coating, the sliding friction resistance between the support and the slide groove can be significantly reduced, vertical displacement jamming can be avoided, component wear can be reduced, and the service life of the vibration-resistant support assembly can be extended.

[0021] Beneficial effects:

[0022] 1. Optimized force path and significantly improved structural stability: The present invention adopts an arc-shaped connector. Through the structural design of connecting the two ends to the left and right supports and the middle to the hydraulic support, the arc-shaped connector is mainly subjected to vertical compression when bearing vibration loads, rather than the bending force of the traditional structure, which makes full use of the compressive strength of the metal material. At the same time, by limiting the support to retain only the vertical degree of freedom through the limiting groove, more effective vibration constraint and stability control are achieved.

[0023] 2. Constructing a closed-loop hydraulic vibration reduction system to effectively suppress and dissipate wide-frequency vibration: This invention forms a semi-active vibration reduction system by connecting the hydraulic guide support column and the hydraulic support seat through a closed-loop oil circuit, combined with a damping throttle valve and an energy storage tank. When the vibrating component generates vertical vibration, the downward displacement of the left and right supports causes the hydraulic guide support column to compress, the oil pressure increases and is simultaneously transmitted to the hydraulic support seat, causing the hydraulic support seat to lift the arc-shaped connecting piece upward, forming a reverse support force opposite to the vibration direction, which cancels the vibration load in real time. At the same time, the mechanical energy of the vibration is converted into heat energy dissipation through the throttling effect of the damping throttle valve, effectively suppressing the vibration amplitude and avoiding reciprocating resonance.

[0024] 3. Lightweight and high rigidity are combined to suit roof installation scenarios: The outer frame of this invention adopts an aluminum alloy truss structure, and the vibration-resistant base adopts a hollow reinforced casting structure. While ensuring the overall rigidity and vibration resistance of the structure, it reduces the weight by more than 40% compared with the traditional solid steel structure base, and strictly meets the load limit requirements for roof installation.

Figure 1-6 As shown, it includes an outer frame 1, which is a truss frame structure welded from high-strength aluminum alloy profiles, with crisscrossing reinforcing ribs on the inner wall. An end inspection door 3 is provided at the end of the outer frame 1, and the interior is divided into a pump compartment 6 and a control compartment 7 by vibration isolation baffles. An integrated control cabinet 2 and an electrical cabinet 4 are installed in the control compartment 7. The side wall of the outer frame 1 is provided with inlet and outlet water interfaces 5 corresponding to the hydraulic module.

[0035] Several sets of parallel hydraulic modules are installed inside the pump compartment 6. The hydraulic modules include a pump 8 and a motor 10 connected coaxially, which together constitute a vibrating component. The vibrating component is rigidly fixed to the upper surface of the U-shaped support bracket 11. The flanges on both sides of the support bracket 11 extend outward, and a reinforcing rib is provided in the middle to improve the structural strength. The bottom ends of the support bracket 11 are fixed to the upper surfaces of the left and right supports, respectively.

[0036] The vibrating component is supported by the anti-vibration support assembly, which includes a support bracket 11, a left support, a right support, an anti-vibration base 9, and an upper cover plate 12. The upper cover plate 12 covers the top of the anti-vibration base 9 to form an installation chamber. The upper cover plate 12 has a limiting groove 121 that matches the left and right supports. The side walls of the left and right supports and the inner wall of the limiting groove 121 are coated with a graphite self-lubricating wear-resistant coating, retaining only the vertical displacement degree of freedom.

[0037] The mounting chamber is equipped with several arc-shaped connectors 15, whose two ends are connected to the lower surfaces of the left and right supports, and whose middle part is connected to the top of the hydraulic support seat 19. The bottom of the hydraulic support seat 19 is fixed to the bottom surface of the inner wall of the vibration-damping base 9 through the lower mounting plate 20. Several single-acting hydraulic guide support columns 16 are provided on the bottom surface of the inner wall of the vibration-damping base 9, which are arranged at intervals with the arc-shaped connectors 15. The top of the piston rod is connected to the lower surface of the left / right support.

[0038] The rodless chamber of the hydraulic guide support column 16 and the rodless chamber of the hydraulic support seat 19 are connected in a closed loop via a connecting oil circuit 17. A bidirectional adjustable damping throttle valve and an energy storage tank 18 are connected in series on the oil circuit 17. The energy storage tank 18 has a preset inflation pressure that matches the static working pressure of the hydraulic system, and its volume is 6% of the total oil volume of the hydraulic system. Each hydraulic module is equipped with an independent anti-vibration support assembly, and the hydraulic systems are independent of each other to avoid vibration interference between groups.

[0039] Example 2

[0040] This embodiment provides a highly stable integrated cold source container system adapted to high-power hydraulic modules and high-vibration conditions. Based on Embodiment 1, it further improves vibration reduction stability and structural reliability under heavy loads and high-frequency vibrations. The specific structure is as follows:

[0041] Inside the installation chamber, the arc-shaped connector 15 is made of high-strength spring steel and is arranged alternately and evenly with the hydraulic guide support column 16; the hydraulic guide support column 16 is a single-acting hydraulic cylinder.

[0042] In this embodiment, the damping throttle valve adopts a high-precision bidirectional adjustable structure, and the damping coefficient adjustment range is expanded to 10 N·s / mm; the energy storage tank 18 has a volume of 8% of the total oil volume of the hydraulic system, and the preset inflation pressure is precisely matched according to the dynamic working pressure of the high-power water pump, which enhances the pressure buffering and shock absorption capacity, quickly suppresses instantaneous vibration peaks, and avoids sudden changes in hydraulic system pressure.

[0043] Working principle: When the water pump 8 and motor 10 generate vertical vibration, the left and right supports move up and down with the vibration, which drives the hydraulic guide support column 16 to extend and retract. The oil pressure change is synchronously transmitted to the hydraulic support seat 19, which pushes the arc-shaped connecting piece 15 to generate a reverse support force to offset the vibration load. The mechanical energy of the vibration is converted into heat energy through the throttling effect of the damping throttle valve. The energy storage tank 18 stabilizes the system oil pressure and buffers pressure fluctuations, realizing the adaptive suppression and energy dissipation of wide-frequency vibration.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
