Description
Technical Field
[0001] The present invention relates to the technical field of waste heat utilization in data centers, and in particular to a system for fish farming based on waste heat from liquid-cooled data centers. Background Art
[0002] my country's data center industry is developing rapidly. Data centers contain a large number of servers, which generate heat during operation. Directly discharging this heat would lead to energy waste and environmental problems, leading to increasing attention on energy efficiency and waste heat recovery technologies. Furthermore, data centers emit large and stable amounts of heat. Interseasonal phase change heat storage can improve waste heat utilization, addressing the mismatch between heating supply and demand in time and space, and effectively ensuring stable heating throughout the year. Therefore, this system utilizes waste heat from data centers. The waste heat generated by liquid-cooled data centers can be directly used for hot water production. This system directly utilizes this heat, directing water from different temperature ranges into fish ponds for different fish farming conditions, achieving fish farming at varying water temperatures. Summary of the Invention
[0003] In response to the above-mentioned defects or improvement needs of the existing technology, this patent provides a data center waste heat utilization technology. The system uses the waste heat of the liquid-cooled data center for fish farming. Specifically, a heat exchanger is added between the primary side modules to directly use the waste heat for fish farming. This not only recycles the waste heat and saves energy, but also reduces the cost of fish farming.
[0004] To achieve the above objectives, this patent provides a fish farming technology based on waste heat from liquid-cooled data centers, including: a primary side module, a control module, and a waste heat recovery module;

[0008] Optionally, the hot end waste heat recovery module includes a warm water fish farming pond, a hot end heat exchanger, a hot end temperature sensor, a hot end pump, and a valve, which is used to recover waste heat between the plate heat exchanger and the cold source. The higher temperature water obtained through heat transfer is transported to the warm water fish farming pond through a pipeline.
[0009] Optionally, multiple hot-end heat exchangers are added to the pipeline between the plate heat exchanger and the cold source to obtain water at different temperatures, thereby achieving stepped water temperature fish farming (such as 20°C to 50°C) to meet the water temperature requirements of different fish farmers.

Water at a lower temperature (about 20°C) is transported to the cold water fish farming pond through a pipeline.
[0011] Optionally, the water temperature of the fish pond can be specifically controlled to a set temperature range through a valve, thereby achieving the purpose of adjusting the water temperature according to different needs.

When the temperature in the water pipe is higher or lower than the set temperature range, the temperature sensor will transmit the signal to the corresponding control panel, and the control panel will adjust the valves of the heat exchanger branch and its bypass to adjust its temperature to within the set range.
[0013] Optionally, the control module is also used to set the flow range according to the requirements of the fish farmer.

[0028] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the system is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0029] See also Figure 1 , a system for fish farming based on waste heat from a liquid-cooled data center, including: a primary side module, a control module, and a waste heat recovery module.
[0030] Among them, the primary side module includes a liquid-cooled data center, a cold source 2, a cooling pump 1, and a plate heat exchanger 5.
[0031] Optionally, the waste heat recovery module includes a hot end waste heat recovery module and a cold end waste heat recovery module.
[0032] Optionally, the hot end waste heat recovery module includes a warm water fish farming pond 7, a hot end heat exchanger 3, a hot end temperature sensor 12, a hot end pump 10, a valve 14, a valve 15, and a valve 16.
[0033] Optionally, the cold end waste heat recovery module includes a cold water fish farming pond 6 , a cold end heat exchanger 4 , a cold end temperature sensor 13 , a cold end pump 11 , a valve 17 , a valve 18 , and a valve 19 .
[0034] Optionally, the control module includes a hot end control panel 9 and a cold end control panel 8.
[0035] In an embodiment of the present system, the primary side module is a cooling loop of the entire liquid-cooled data center, and is used to provide cooling to the data center.
[0036] In an embodiment of the present system, the waste heat recovery module is used to recover waste heat from a liquid-cooled data center.
[0037] The hot end waste heat recovery module is used to recover waste heat between the plate heat exchanger 5 and the cold source 2, and the higher temperature water obtained through heat transfer is transported to the warm water fish farming pond 7 through a pipeline.
[0038] We can also realize parallel cascade fish ponds. We have added multiple hot-end heat exchangers in the pipeline between the plate heat exchanger and the cold source to realize cascade water temperature (20℃~50℃) for fish farming to meet the water temperature requirements of different fish farmers.
[0039] The cold end waste heat recovery module is used to recover waste heat between the cooling pump 1 and the plate heat exchanger 5, and water with a lower temperature (about 20°C) is transported to the cold water fish farming pond 6 through a pipeline.
[0040] In the embodiment of the present system, the control module receives signal feedback from the temperature sensor through the hot-end control panel 9 and the cold-end control panel 8, thereby controlling the flow regulating valves in the primary-side module and the waste heat recovery module.
[0041] More specifically, the temperature sensor will monitor the temperature in the water pipe in real time. When the temperature in the water pipe is higher or lower than the set temperature range, the temperature sensor will transmit a signal to the control panel, and the control panel will adjust the valves of the heat exchanger branch and its bypass to adjust the temperature to within the set range.
[0042] In the hot-end control module, when the hot-end temperature sensor 12 detects that the temperature in the water pipe is higher than the set temperature range, the hot-end control panel 9 will adjust the valve 15 on the branch of the heat exchanger 3 and the valve 16 on the heat exchanger bypass to a larger value after receiving the signal from the temperature sensor 12, thereby achieving the purpose of reducing the heat exchange amount and lowering the temperature. When the temperature sensor 12 monitors in real time that the water temperature drops to the set temperature range, the new signal will be fed back to the control panel 9, and the control panel 9 will stop valve adjustment after receiving it; when the temperature sensor 12 detects that the temperature in the water pipe is lower than the set temperature range, the opposite will happen.
[0043] In the cold-end control module, when the cold-end temperature sensor 13 detects that the temperature in the water pipe is higher than the set temperature range, the cold-end control panel 8 will adjust the valve 19 on the heat exchanger 4 branch and the valve 18 on the heat exchanger bypass to a larger value after receiving the signal from the temperature sensor 13, thereby achieving the purpose of reducing the heat exchange and lowering the temperature. When the temperature sensor 13 monitors in real time that the water temperature drops to the set temperature range, the new signal will be fed back to the control panel 8, and the control panel 8 will stop valve adjustment after receiving it; when the temperature sensor 13 detects that the temperature in the water pipe is lower than the set temperature range, the opposite is true.
[0044] At the same time, the control module can also adjust the flow of the fish pond water supply pipeline. Specifically, the flow range can be set according to the requirements of the fish farmer. When the flow in the water pipe is higher or lower than the set range, the control module will adjust the valve of the fish pond water supply pipeline to ensure that the flow is within the set range.
[0045] Optionally, in the hot-end control module, the hot-end control panel 9 will adjust the valve 14 of the fish pond water supply pipeline to ensure that the flow rate is within the set range.
[0046] Optionally, in the cold-end control module, the hot-end control panel 8 will adjust the valve 17 of the fish pond water supply pipeline to ensure that the flow rate is within the set range.
[0047] This system has the following beneficial effects:
[0048] 1. This system uses liquid-cooled data center waste heat for fish farming, recovering waste heat, saving energy, and reducing fish farming costs;
[0049] 2. This system is equipped with hot-end waste heat recovery modules and cold-end waste heat recovery modules to recover waste heat from water of different temperatures in the primary side modules;
[0050] 3. This system adds a hot-end heat exchanger to the pipe between the plate heat exchanger and the cold source. The higher-temperature water after heat transfer is transported to the warm-water fish pond through the pipe. We have also invented a parallel cascade fish pond. We have added multiple hot-end heat exchangers to the pipe between the plate heat exchanger and the cold source, realizing cascade water temperature (20℃~50℃) for fish farming to meet the water temperature requirements of different fish farmers.
[0051] 4. This system also adds a cold-end heat exchanger in the pipeline between the cooling water pump and the plate heat exchanger. The water with a lower temperature (around 20°C) is transported to the cold water aquaculture pond through the pipeline, realizing fish farming modes with different water temperatures.
[0052] 5. This system monitors and adjusts the system operation in real time through temperature sensors, control panels, and valves. It can not only adjust the water temperature, but also adjust the flow rate to further meet the real-time needs of fish farmers, recycle waste heat, reduce energy consumption, and save costs.
