Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0031] The following will combine the accompanying drawings and through specific embodiments and their application scenarios to elaborate in detail on the prefabricated modular waste heat recovery system provided by the embodiments of the present application.

[0032] The embodiments of the present application provide a prefabricated modular waste heat recovery system, as Figure 1 shown, including a data center waste heat generation unit 100, a waste heat recovery unit 200, and a waste heat user unit 300. Among them, the data center waste heat generation unit 100 is used to output the waste heat generated by the data center to the waste heat recovery unit 200. After receiving the waste heat of the data center output by the data center waste heat generation unit 100, the waste heat recovery unit 200 outputs it to the waste heat user unit 300. After the waste heat user unit 300 utilizes the waste heat, it re-outputs the cooled refrigerant to the waste heat recovery unit 200, and then the waste heat recovery unit 200 circulates and outputs it to the data center waste heat generation unit 100 to realize the cooling of the data center.

[0033] It can be understood that the heat transfer between the data center waste heat generation unit 100, the waste heat recovery unit 200, and the waste heat user unit 300 is transmitted by the flow of the refrigerant, and the waste heat user unit 300 can be set as any unit or system that requires heat input.

[0034] In the embodiments of the present application, the above-mentioned prefabricated modular waste heat recovery system is adopted. The waste heat user unit 300 collects the waste heat generated by the data center waste heat generation unit 100 of the data center and outputs the collected waste heat to the waste heat user unit 300 to realize the utilization of the waste heat, that is, the waste heat recovery unit 200 is used to realize the heat recovery of the data center and supply the heat to the area that requires heat, so as to maximize the energy utilization, and finally achieve the purposes of energy conservation and carbon reduction, reducing the enterprise cost, and improving the investment return.

[0035] In a preferred embodiment, as Figure 2As shown in the figure, the refrigerant delivery path between the waste heat generation unit 100 of the data center, the waste heat recovery unit 200, and the waste heat user unit 300 is set to install double-layer insulated pipes through pipe interfaces. Specifically, the data center waste heat generation unit 100 is provided with a first pipe interface 410, the waste heat recovery unit 200 is provided with a second pipe interface 420, and a first double-layer insulated pipe 510 is installed between the first pipe interface 410 and the second pipe interface 420. The waste heat generated by the data center waste heat generation unit 100 is transported to the waste heat recovery unit 200 through the first double-layer insulated pipe 510, thereby enabling the waste heat recovery unit 200 to recover the waste heat.

[0036] The waste heat recovery unit 200 is further provided with a third pipe interface 430, the waste heat user unit 300 is provided with a fourth pipe interface 440, and a second double-layer insulated pipe 520 is installed between the third pipe interface 430 and the fourth pipe interface 440. The waste heat recovered by the waste heat recovery unit 200 is transported to the waste heat user unit 300 through the second double-layer insulated pipe 520, thereby enabling the waste heat user unit 300 to effectively utilize the waste heat.

[0037] The waste heat user unit 300 is further provided with a fifth pipe interface 450, the waste heat recovery unit 200 is further provided with a sixth pipe interface 460, and a third double-layer insulated pipe 530 is installed between the fifth pipe interface 450 and the sixth pipe interface 460. The refrigerant after the waste heat user unit 300 utilizes the waste heat is transported to the waste heat recovery unit 200 through the third double-layer insulated pipe 530, so as to facilitate the waste heat recovery unit 200 to reprocess the reused refrigerant.

[0038] The waste heat recovery unit 200 is further provided with a seventh pipe interface 470, the data center waste heat generation unit 100 is further provided with an eighth pipe interface 480, and a fourth double-layer insulated pipe 540 is installed between the seventh pipe interface 470 and the eighth pipe interface 480. The refrigerant after the waste heat recovery unit 200 utilizes the waste heat is transported back to the data center waste heat generation unit 100 through the fourth double-layer insulated pipe 540, thereby realizing the circulating cooling of the data center waste heat generation unit 100 by the cooled refrigerant.

[0039] It can be understood that the interface standards of the refrigerant delivery path are arranged in a standard manner, thereby reducing the pipe resistance, and the connection between the pipe interface and the double-layer insulated pipe is wrapped with a vacuum heat baffle.

[0040] In the embodiment of the present application, by adopting the above-mentioned prefabricated modular waste heat recovery system, double-layer insulated pipes are installed between the waste heat generation unit 100 of the data center, the waste heat recovery unit 200, and the waste heat user unit 300 through pipe interfaces, thereby solving the pipe layout of the prefabricated module waste heat recovery, shortening the distance between the pipe interfaces, and further reducing the overall volume of the prefabricated modular waste heat recovery system.

[0041] It is understandable that the refrigerant used in the waste heat recovery system can be a gaseous refrigerant or a liquid refrigerant, as long as the heat transfer efficiency and fluidity can be ensured.

[0042] In a preferred embodiment, as Figure 3 , Figure 4 shown, the double-layer heat-insulated pipe includes a refrigerant channel 501. A first heat-insulating layer 502 and a second heat-insulating layer 503 are successively coated on the outer circumferential surface of the refrigerant channel 501 along its radial direction. Flange interfaces 504 are provided at both ends of the double-layer heat-insulated pipe for mating with pipe interface flanges.

[0043] Specifically, the first heat-insulating layer 502 is a silicone heat-resistant paint coating, and the second heat-insulating layer 503 is one of a rock wool layer, a glass fiber cotton layer, a polyurethane foam plastic layer, and a microporous silicate layer.

[0044] In the embodiment of the present application, the above-mentioned prefabricated modular waste heat recovery system is adopted to wrap the refrigerant channel 501 with double-layer heat-insulating materials, thereby improving the temperature constancy during the refrigerant transportation, enhancing the heat exchange efficiency of the refrigerant, and at the same time, assembling the prefabricated modules through the flange interfaces 504, which is convenient for installation.

[0045] In a preferred embodiment, the waste heat recovery unit 200 includes a temperature control module. The temperature control module is used to measure the refrigerant input from the waste heat generation unit 100 of the data center and the waste heat user unit 300, and control the output route of the refrigerant based on the waste heat temperature of the refrigerant.

[0046] Specifically, if the temperature of the refrigerant input from the waste heat generation unit 100 of the data center to the waste heat recovery unit 200 is relatively high, it is output to the waste heat user unit 300 to realize the secondary utilization of the refrigerant. Conversely, it is directly transported to the waste heat generation unit 100 of the data center to realize the circulating cooling of the waste heat generation unit 100 of the data center; similarly, if the temperature of the refrigerant input from the waste heat user unit 300 to the waste heat recovery unit 200 is relatively high, it is output to the waste heat user unit 300 to realize the re-use of the refrigerant. Conversely, it is transported to the waste heat generation unit 100 of the data center to realize the circulating cooling of the waste heat generation unit 100 of the data center.

[0047] In the embodiment of the present application, the above-mentioned prefabricated modular waste heat recovery system is adopted to monitor the waste heat of the refrigerant through the temperature control module, thereby making the utilization of the waste heat generated by the data center more reasonable, improving the waste heat utilization efficiency, and further achieving the environmental protection effects of energy conservation and carbon reduction.
