Description

Technical Field

[0001] This utility model relates generally to the technical field of refrigeration equipment, and more specifically to a containerized pre-refrigeration station system. Background Technology

[0002] With the large-scale development of cloud computing and large-scale model training, more and more data centers are being built and put into operation. However, traditional cold stations require on-site assembly of equipment and welding of pipelines, resulting in problems such as long construction cycles, uncontrollable installation quality, and large site occupancy. To solve this problem, containerized prefabricated cold stations have emerged. Current containerized cold station integration methods tend to be more focused on single-container or planar layouts, which, due to space constraints, lead to equipment congestion, maintenance difficulties, inability to integrate cooling towers, or increased floor space and the need for on-site welding of pipelines between containers.

[0003] Therefore, there is a need to provide a containerized pre-cooling station system to at least partially solve the above problems. Utility Model Content

[0022] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0023] This utility model provides a containerized pre-cooling station system.

[0024] Please see Figures 1 to 4 The containerized pre-refrigeration station system 100 includes a first container 110, a second container 120, and a cooling tower 131. A refrigeration unit 140 is installed inside the first container 110. The second container 120 is located outside the first container 110 and connected to its top. A heat exchange unit 150 is installed inside the second container 120. The cooling tower 131 is located outside the second container 120 and connected to its top. The interiors of the first container 110 and the second container 120 are in communication. The refrigeration unit 140 is at least partially connected to the heat exchange unit 150. The cooling tower 131 is connected to both the refrigeration unit 140 and the heat exchange unit 150.

[0025] According to the containerized pre-refrigeration station system 100 of this scheme, the stacking of the first container 110 and the second container 120 expands the operation and maintenance space and reduces the floor space required. The integrated devices (such as the refrigeration unit 140 and the heat exchange unit 150) inside the first container 110 and the second container 120 can be operated independently. The cooling tower 131 is installed on top of the second container 120, further reducing the floor space required and giving this refrigeration station system a significant advantage in terms of physical space. Functionally, it also combines mechanical refrigeration and natural heat exchange, improving the power consumption of the refrigeration system and reducing the power usage effectiveness (PUE).

[0026] Figure 1 and Figure 2 In this configuration, the first container 110 and the second container 120 are interconnected via a splicing device 130. The splicing device 130 seals the seams between the containers (i.e., the first container 110 and the second container 120), achieving waterproofing and sealing. Further details can be found here. Figures 1 to 3 The refrigeration unit 140 includes a chiller 141, a first cooling water piping assembly 142, and a first chilled water piping assembly 143. Specifically, the first cooling water piping assembly 142 is used to connect to the chiller 141 and the cooling tower 131. One end of the first chilled water piping assembly 143 is used to connect to the chiller 141, and the first chilled water piping assembly 143 is also provided with a first interface. It should be noted that the chiller 141 generates chilled water (usually supplied at 7°C) through its built-in evaporator, for example, and flows through the first chilled water piping assembly 143 to the user terminal (such as a data center server room air conditioner) for heat exchange. After absorbing heat, it returns to the chiller (usually returned at 12°C), forming a closed loop. The cooling water is heated in the chiller 141, and its temperature rises (for example, from 32°C to 37°C). Then, it flows through the first cooling water piping assembly 142 to the cooling tower 131 to be cooled, and its temperature drops (from 37°C back to 32°C), completing the cycle. The first interface is used to connect to the chilled water supply and return network on the user side, enabling "plug and play". Its ultimate target is, for example, the air conditioning terminal equipment in the data center, providing it with cooling capacity.

[0027] Please continue reading. Figures 1 to 3 The interior of the first container 110 is also provided with at least one of the following: an electrical distribution cabinet 111, a first ladder 115, and a fire cabinet 112; and / or the first container 110 is also provided with a first ventilation device 116 that connects the outside world and the interior of the first container 110. Figures 1 to 3 The first container 110 contains an electrical distribution cabinet 111, a first ladder 115, and a fire cabinet 112. The first container 110 is equipped with a first ventilation system 116 connecting the outside to the interior of the first container 110. The first ventilation system 116, for example, uses rainproof louvered mechanical exhaust to dissipate heat generated by the chiller unit (chiller 141 and its accessories). A first guardrail 117 is also provided around the first ladder 115, located inside and connected to the first container 110. The first ladder 115 facilitates personnel climbing for maintenance.

[0028] Furthermore, the interior of the first container 110 is also equipped with a partition 113, which is connected to the inner wall of the first container 110. Along the thickness direction of the partition 113, the refrigeration unit 140 and the electrical distribution cabinet 111 are located on opposite sides of the partition 113. The partition 113 has passageways for personnel to pass through on both sides. Along the thickness direction of the partition 113, the first ladder 115 and the electrical distribution cabinet 111 are located on the same side of the partition 113. The fire cabinet 112 and the refrigeration unit 140 are also located on the same side of the partition 113. The partition 113 can be constructed, for example, as a fireproof isolation wall, to isolate the electrical distribution cabinet 111 separately, facilitating operation by maintenance personnel.

[0029] Please see now Figure 1 , Figure 2 and Figure 4 The heat exchange device 150 includes a heat exchanger 151, a second cooling water piping assembly 152, and a second chilled water piping assembly 153. The second cooling water piping assembly 152 is used to connect the heat exchanger 151 and the cooling tower 131. One end of the second chilled water piping assembly 153 is used to connect to the heat exchanger 151, and the second chilled water assembly is also provided with a second interface. The heat exchanger 151 is constructed, for example, as a plate heat exchanger. It should be noted that the heat exchanger 151 itself does not generate cooling water or chilled water; it is a heat exchanger. In natural cooling mode, cooling water flows through the primary side of the heat exchanger 151, absorbing heat from the chilled water on the secondary side, increasing the temperature of the cooling water itself, and then flows through the second cooling water piping assembly 152 to the cooling tower 131 to dissipate heat. Chilled water flows through the secondary side of the heat exchanger 151, transferring heat to the cooling water on the primary side, decreasing the temperature of the chilled water, and then flows through the second chilled water piping assembly 153 to the user terminal for cooling. Cooling water and chilled water exchange heat within heat exchanger 151, but circulate independently and do not mix. The second interface is a standardized quick-connect point between the chiller system and the user-side chilled water network. The chilled water ultimately serves terminal cooling equipment such as air conditioners in data centers, providing cooling capacity to ensure that IT (Information Technology) equipment operates at safe temperatures. In other words, heat exchanger 151 is responsible for heat exchange in natural cooling mode, and chilled water connects to the user-side network through the second interface to ultimately cool the data center's terminal equipment. It can be understood that when natural cooling mode is insufficient to meet usage requirements, chiller 141 and heat exchanger 151 can operate simultaneously.

[0030] Furthermore, the interior of the second container 120 is also equipped with a water treatment device 122 and / or a second ladder 126; and / or the second container 120 is also equipped with a second ventilation device 128 that connects to the outside and the interior of the second container 120. Figure 1 and Figure 2The second container 120 houses a water treatment unit 122 and a second ladder 126. The second container 120 also has a second ventilation system 128 connecting it to the outside and the interior of the second container 120. The water treatment unit 122 improves the water quality of the entire chiller plant system. The water treatment unit 122 is mounted, for example, to the floor 121 of the second container 120 via a first base 123. The second ladder 126 facilitates personnel climbing for maintenance. A second guardrail 127 is installed around the second ladder 126, located inside and connected to the second container 120. The second ventilation system 128, for example, uses rainproof louvered mechanical exhaust to dissipate heat generated by the heat exchange unit (heat exchanger 151 and its accessories). The second container 120 also houses a cooling water pump 124 and a corresponding cooling water delivery piping assembly 129. The cooling water pump 124 is connected to the cooling tower 131, the chiller 141, and the heat exchanger 151. In mechanical refrigeration mode, cooling water pump 124 drives cooling water to dissipate heat from chiller 141. The approximate flow direction of the cooling water is: cooling tower 131 → cooling water pump 124 → chiller 141 → return to cooling tower 131. In natural cooling mode, cooling water pump 124 drives cooling water to absorb heat from chilled water in heat exchanger 151. The approximate flow direction of the cooling water is: cooling tower 131 → cooling water pump 124 → heat exchanger 151 (primary side) → return to cooling tower 131. Therefore, cooling water pump 124 is the hub and power source connecting cooling tower 131 to the two core heat sources (chiller 141 or heat exchanger 151). The valves in the cooling water delivery pipeline assembly 129 control the switching of its service target, thereby achieving efficient heat dissipation in different operating modes. A mounting pipeline 133 is provided at cooling tower 131 to connect to chiller 141 and heat exchanger 151 respectively. The cooling tower 131 is mounted to the top of the second container 120, for example, via a second base 132. The second base 132, for example, has a shock-absorbing function.

[0031] Please see now Figures 1 to 4 The top of the first container 110 is located at the first entrance / exit 118, which connects to the interior of the second container 120. For example, the first container 110 is constructed as an open-top container. The second container 120 includes a second entrance / exit 125 located at the floor 121, which connects to the first entrance / exit 118 and the interior of both containers 120. The floor 121 is, for example, constructed as a steel grid structure. The grid floor, together with the aforementioned entrance / exit, forms a three-dimensional maintenance passage, solving the maintenance challenges of a compact space.

[0032] Furthermore, the containerized pre-cooling station system 100 also includes a third piping assembly 160, which is connected to the refrigeration unit 140 and the heat exchange unit 150. The third piping assembly 160 is also provided with a third interface 161, which is used to connect to an end user or to other containerized pre-cooling station systems 100.

[0033] The containerized pre-cooling station system 100 of this utility model is suitable for rapid cooling needs in scenarios such as data centers, temporary buildings, and industrial plants.

[0034] According to the containerized pre-cooling station system of this utility model, the equipment and pipeline pre-assembly rate in the factory is no less than 95%, reducing the amount of on-site engineering. A reserved pipeline ring network (e.g., a third pipeline component) enables parallel capacity expansion, and the cooling towers are quickly assembled on-site through factory-prefabricated pipe sections (e.g., assembled pipelines). This vertically integrated method greatly reduces the floor space occupied by the cooling station, saving land resources.
