[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] As part of the inventive concept of this utility model, before describing the embodiments of this utility model, it is necessary to analyze the reasons for the poor heat dissipation effect of data centers in related technologies, and obtain the technical solution of the embodiments of this application through reasonable analysis.
[0021] In related technologies, traditional data center cooling primarily relies on air conditioning systems, which absorb and dissipate heat through refrigerant circulation. However, this approach has several limitations. First, air conditioning systems consume a lot of energy, increasing the operating costs of data centers. Second, the heat generated during cooling is often directly released into the environment, resulting in energy waste. Furthermore, as data centers continue to expand in scale, traditional cooling methods may struggle to meet their heat dissipation demands, leading to excessively high equipment operating temperatures and impacting equipment performance and lifespan.
[0022] To improve the energy efficiency of data centers, reduce operating costs, and meet their heat dissipation needs, heat recovery technology has emerged. The core idea of heat recovery technology is to recover and utilize the heat generated by data centers, rather than simply releasing it. Through heat recovery systems, the heat generated by data centers can be used to heat water, drive heat pumps, etc., achieving energy recycling, reducing energy waste, and decreasing dependence on traditional energy sources; at the same time, it also reduces thermal pollution to the environment.
[0023] To address this issue, this invention provides a data center heat recovery system. Through a multi-stage heat exchange mechanism involving a first heat exchanger and a second heat exchanger, heat can be transferred and utilized step by step, maximizing heat recovery efficiency and thus solving the problem of poor heat dissipation in data centers.
[0024] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0025] An embodiment of this utility model provides a data center heat recovery system, such as... Figures 1 to 3 As shown, it includes an outer shell 1, a water tank 2, a first heat exchange mechanism 3, and a second heat exchange mechanism 4.
[0026] The outer shell 1 constitutes the external structure of the data center heat recovery system. The appearance of the outer shell 1 can be designed as needed and is not limited here. The outer shell 1 is provided with a water inlet 11 and a water outlet 12.
[0027] Water tank 2 is located inside the outer casing 1 and is connected to inlet 11 and outlet 12. Water tank 2 is capable of collecting heat. Specifically, water tank 2 is capable of collecting heat generated by the data center equipment during operation.
[0028] The first heat exchange mechanism 3 is located inside the outer shell 1. The function of the first heat exchange mechanism 3 is heat exchange. Specifically, the first heat exchange mechanism 3 is connected to the water tank 2. The first heat exchange mechanism 3 receives high-temperature water from inside the water tank 2, exchanges heat with the high-temperature water to convert it into low-temperature water, and then transports the low-temperature water back into the water tank 2.
[0029] During the operation of the first heat exchange mechanism 3, the high-temperature water inside the water tank 2 flows into the first heat exchange mechanism 3 for heat exchange, and then the temperature of the high-temperature water in the first heat exchange mechanism 3 decreases to low-temperature water before flowing into the water tank 2.
[0030] The second heat exchange mechanism 4 is located inside the outer shell 1. The function of the second heat exchange mechanism 4 is heat exchange. One end of the second heat exchange mechanism 4 is connected to the first heat exchange mechanism 3, and the other end of the second heat exchange mechanism 4 is connected to the water tank 2.
[0031] During the operation of the second heat exchange mechanism 4, the second heat exchange mechanism 4 can exchange heat with the first heat exchange mechanism 3 and transfer the heat to the low-temperature water inside the water tank 2, so that the temperature of the low-temperature water inside the water tank 2 rises and becomes high-temperature water.
[0032] In the embodiments of this utility model, the water tank 2 includes a first tank body 21, a first baffle 213, and a second baffle 214.
[0033] The first housing 21 forms the outer shell of the water tank 2, which is usually a hollow cuboid structure. The appearance of the first housing 21 can be designed as needed and is not limited here. Specifically, the first housing 21 has a first side wall 211 and a second side wall 212 that are arranged opposite to each other.
[0034] There are multiple first baffles 213. In this embodiment, "multiple first baffles 213" specifically refers to two or more first baffles 213, such as two, three, four, five, six, seven, or eight first baffles 213. This embodiment uses three first baffles 213 as an example. Specifically, the multiple first baffles 213 are spaced apart on the first sidewall 211, and gaps are left between the multiple first baffles 213 and the second sidewall 212 to allow water in the water tank 2 to flow between the various first baffles 213.
[0035] There are multiple second baffles 214. In this embodiment, multiple second baffles 214 specifically refers to two or more second baffles 214, such as two second baffles 214, three second baffles 214, four second baffles 214, five second baffles 214, six second baffles 214, seven second baffles 214, eight second baffles 214, etc. In this embodiment, three second baffles 214 are used as an example. Specifically, the multiple second baffles 214 are spaced apart on the second side wall 212, and there are gaps between the multiple second baffles 214 and the first side wall 211 so that the water in the water tank 2 can flow through the gaps to the spaces between the second baffles 214.
[0036] Multiple first baffles 213 and multiple second baffles 214 are arranged alternately. Specifically, the arrangement is such that the first baffles 213, the second baffles 214, the first baffles 213, the second baffles 214, and the first baffles 213 are arranged alternately at intervals.
[0037] In the above technical solution, because multiple first baffles 213 are spaced apart on the first sidewall 211, and gaps are left between the multiple first baffles 213 and the second sidewall 212, and multiple second baffles 214 are spaced apart on the second sidewall 212, and gaps are left between the multiple second baffles 214 and the first sidewall 211, an S-shaped bend in the water tank 2 is formed inside. This allows the high-temperature water to flow slowly in the S-shaped bend, extending the residence time of the high-temperature water in the water tank 2, thereby more fully absorbing heat. This S-shaped bend in the water channel structure is conducive to the concentrated recovery of heat, providing a foundation for subsequent heat utilization.
[0038] like Figure 4 As shown, in the embodiment of this utility model, the first heat exchange mechanism 3 includes a water pump 31, a heat exchange tube 32, and a first air box 33.
[0039] The function of the water pump 31 is to transport the liquid and increase its energy. Specifically, the water pump 31 is connected to the water tank 2.
[0040] One end of the heat exchange tube 32 is connected to the water pump 31, and the other end of the heat exchange tube 32 is connected to the water tank 2. The first air box 33 is located on the side wall of the heat exchange tube 32 facing the outer casing 1.
[0041] During the operation of the first heat exchange mechanism 3, the water pump 31 starts, delivering the high-temperature water in the water tank 2 to the heat exchange tube 32. Since the heat exchange tube 32 is positioned opposite to the first air box 33, the high-temperature water flows in the heat exchange tube 32, and the heat exchange tube 32 comes into contact with the gas flowing in the first air box 33. The heat in the high-temperature water is transferred to the gas flowing in the first air box 33 through the heat exchange tube 32, thereby reducing the temperature of the high-temperature water in the heat exchange tube 32 to low-temperature water.
[0042] Furthermore, the outer surface of the heat exchange tube 32 is provided with a plurality of heat exchange plates 321, and the plurality of heat exchange plates 321 are spaced apart on the outer surface of the heat exchange tube 32. In this embodiment, "a plurality of heat exchange plates 321" specifically refers to two or more heat exchange plates 321, such as two, three, four, five, six, seven, or eight heat exchange plates 321. This embodiment uses an example of eight heat exchange plates 321 spaced apart on the outer surface of the heat exchange tube 32 for illustration. By spaced apart on the outer surface of the heat exchange tube 32, the heat exchange area between the heat exchange tube 32 and the gas flowing in the first air box 33 is increased, improving the heat exchange effect between the heat exchange tube 32 and the first air box 33 and reducing the heat exchange time between the heat exchange tube 32 and the first air box 33.
[0043] like Figure 5 As shown, in this embodiment, the first air box 33 includes a second box body 331, a third baffle 3313 and a fourth baffle 3314.
[0044] The second housing 331 forms the outer shell of the first air box 33, and is usually a rectangular hollow structure. The appearance of the second housing 331 can be designed as needed and is not limited here. Specifically, the second housing 331 has a third side wall 3311 and a fourth side wall 3312 that are arranged opposite to each other.
[0045] There are multiple third baffles 3313. In this embodiment, "multiple third baffles 3313" specifically refers to two or more third baffles 3313, such as two, three, four, five, six, seven, or eight third baffles 3313. This embodiment uses three third baffles 3313 as an example. Specifically, the multiple third baffles 3313 are spaced apart on the third sidewall 3311, and gaps are left between the multiple third baffles 3313 and the fourth sidewall 3312 to allow gas in the first bellows 33 to flow through the gaps between the third baffles 3313.
[0046] There are multiple fourth baffles 3314. In this embodiment, "multiple fourth baffles 3314" specifically refers to two or more fourth baffles 3314, such as two, three, four, five, six, seven, or eight fourth baffles 3314. This embodiment uses three fourth baffles 3314 as an example. Specifically, the multiple fourth baffles 3314 are spaced apart on the fourth sidewall 3312, and gaps are left between the multiple fourth baffles 3314 and the third sidewall 3311 to allow gas in the first bellows 33 to flow through the gaps between the fourth baffles 3314.
[0047] The third baffles 3313 and the fourth baffles 3314 are arranged alternately. Specifically, the arrangement is such that the third baffles 3313, the fourth baffles 3314, the third baffles 3313, the fourth baffles 3314, the third baffles 3313, and the fourth baffles 3314 are arranged alternately at intervals.
[0048] In the above technical solution, since multiple third baffles 3313 are spaced apart on the third side wall 3311, and there is a gap between the multiple third baffles 3313 and the fourth side wall 3312, and multiple fourth baffles 3314 are spaced apart on the fourth side wall 3312, and there is a gap between the multiple fourth baffles 3314 and the third side wall 3311, an S-shaped bend in the air duct is formed inside the first air box 33, which allows the gas to flow slowly in the S-shaped bend, prolonging the time the gas stays in the air duct, and making the gas flowing in the first air box 33 fully contact the heat exchange tube 32, thereby improving the efficiency of heat exchange.
[0049] like Figure 6 As shown, in this embodiment, the second heat exchange mechanism 4 includes a condenser plate 41, an evaporator tube 42, and a compressor pump 43.
[0050] The function of the condenser plate 41 is to exchange heat with other components or media. In this embodiment, the condenser plate 41 is located inside the water tank 2, and the condenser plate 41 is in contact with the water in the water tank 2, thereby enabling heat exchange between the condenser plate 41 and the water in the water tank 2.
[0051] The function of the evaporator tube 42 is to allow the liquid inside the evaporator tube to absorb heat and evaporate, thereby achieving heat transfer and energy conversion. In this embodiment, the evaporator tube 42 contains a refrigerant.
[0052] The function of the compression pump 43 is to perform work on the fluid, increase its pressure, compress its volume, and output high-pressure fluid for subsequent processes.
[0053] Specifically, the compressor pump 43 is connected to the evaporator tube 42. The compressor pump 43 is used to transport the refrigerant from the evaporator tube 42 to the condenser plate 41 and transfer the heat of the refrigerant to the low-temperature water inside the water tank 2 so that the temperature of the low-temperature water rises and becomes high-temperature water.
[0054] In this embodiment, the second heat exchange mechanism 4 also includes an expansion valve 44. The expansion valve 44 functions to throttle and reduce pressure, and to control flow. In this embodiment, the expansion valve 44 throttles and reduces the pressure of the refrigerant, converting it into a low-pressure, low-temperature refrigerant.
[0055] Specifically, one end of the expansion valve 44 is connected to the condenser plate 41, and the other end of the expansion valve 44 is connected to the evaporator tube 42. The expansion valve 44 is used to transport the refrigerant from the condenser plate 41 to the interior of the evaporator tube 42.
[0056] like Figure 7 As shown, in this embodiment, the second heat exchange mechanism 4 also includes a second air box 45.
[0057] The second air box 45 is located on the side wall of the evaporator tube 42 facing the outer casing 1. When the condenser in the evaporator tube 42 evaporates, the condenser in the evaporator tube 42 can absorb the heat of the gas in the second air box 45, thereby reducing the temperature of the gas in the second air box 45.
[0058] The second air box 45 is connected to the first air box 33 through a connecting pipe 345, so that heat exchange can be carried out between the second air box 45 and the first air box 33. As a result, the gas in the first air box 33 will come into contact with the gas flow in the second air box 45, thereby reducing the temperature of the gas in the first air box 33.
[0059] Specifically, the second air box 45 includes a third box body 451, a fifth baffle 4513, and a sixth baffle 4514.
[0060] The third box 451 forms the outer shell of the second air box 45, which is usually a rectangular hollow structure. The appearance of the third box 451 can be designed as needed and is not limited here. The third box 451 has a fifth side wall 4511 and a sixth side wall 4512 that are arranged opposite to each other.
[0061] There are multiple fifth baffles 4513. In this embodiment, "multiple fifth baffles 4513" specifically refers to two or more fifth baffles 4513, such as two, three, four, five, six, seven, or eight fifth baffles 4513. This embodiment uses three fifth baffles 4513 as an example. Specifically, the multiple fifth baffles 4513 are spaced apart on the fifth sidewall 4511, and gaps are left between the multiple fifth baffles 4513 and the sixth sidewall 4512 to allow gas in the second air box 45 to flow through the gaps between the individual fifth baffles 4513.
[0062] There are multiple sixth baffles 4514. In this embodiment, "multiple sixth baffles 4514" specifically refers to two or more sixth baffles 4514, such as two, three, four, five, six, seven, or eight sixth baffles 4514. This embodiment uses three sixth baffles 4514 as an example. Specifically, the multiple sixth baffles 4514 are spaced apart on the sixth sidewall 4512, and gaps are left between the multiple sixth baffles 4514 and the fifth sidewall 4511 to allow gas in the second bellows 45 to flow through the gaps between the various sixth baffles 4514.
[0063] The fifth baffle 4513 and the sixth baffle 4514 are arranged alternately. Specifically, the arrangement is such that the fifth baffle 4513, the sixth baffle 4514, the fifth baffle 4513, the sixth baffle 4514, the fifth baffle 4513, and the sixth baffle 4514 are arranged alternately at intervals.
[0064] In the above technical solution, since multiple fifth baffles 4513 are spaced apart on the fifth side wall 4511, and there is a gap between the multiple fifth baffles 4513 and the sixth side wall 4512, and multiple sixth baffles 4514 are spaced apart on the sixth side wall 4512, and there is a gap between the multiple sixth baffles 4514 and the fifth side wall 4511, an S-shaped bend in the air duct is formed inside the second air box 45. This allows the gas to flow slowly in the S-shaped bend in the air duct, prolonging the time the gas stays in the air duct. This ensures that the gas flowing in the second air box 45 is in full contact with the heat exchange tube 32, thereby improving the efficiency of heat exchange.
[0065] The interior of the outer casing 1 contains an electrical compartment 5. The function of the electrical compartment 5 is to centrally install, protect, and organize electrical equipment and wiring to ensure the safe and stable operation of the electrical system.
[0066] Specifically, the electrical compartment 5 includes an expansion valve 44, a compression pump 43, an electric heater 51, a controller 52, and a temperature sensor 53.
[0067] The electric heater 51 is located inside the water tank 2 and can heat the low-temperature water in the water tank 2 into high-temperature water.
[0068] Temperature sensor 53 is located inside water tank 2 and can measure the temperature of the water inside water tank 2.
[0069] The water pump 31, the compressor pump 43, the electric heater 51, and the temperature sensor 53 are all electrically connected to the controller 52. The controller 52 controls the water pump 31 to deliver water from the water tank 2 to the heat exchange tube 32. It also controls the compressor pump 43 to deliver refrigerant from the evaporator tube 42 to the condenser plate 41. Furthermore, the controller 52 receives the temperature of the water inside the water tank 2 measured by the temperature sensor 53, and when the water temperature inside the water tank 2 is low, it controls the electric heater 51 to heat the water inside the water tank 2.
[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
