Description

Technical Field

[0001] This utility model relates to the field of cooling system technology in the data center industry, specifically to a liquid cooling distribution unit based on phase change cooling. Background Technology

[0002] The existing cooling systems in the data center industry mostly use cooling towers, dry coolers and other equipment to provide chilled water (or solution) and deliver it to the cooling distribution unit. The distribution unit then uses low-temperature water (or solution) to cool the high-temperature coolant and distributes the cooled coolant to the IT equipment that needs cooling.

[0003] However, such equipment is expensive. Secondly, the coolant only undergoes temperature changes during operation, resulting in low heat exchange efficiency. Thirdly, using water or an aqueous solution as cooling water requires a large amount of water resources for the heat dissipation process.

[0004] In view of this, we propose a device that can undergo a refrigerant phase change during circulation, which effectively improves heat exchange efficiency and does not consume water resources during operation. Utility Model Content

[0007] Furthermore, it also includes a one-way valve, which is installed on the pipeline. In practical applications, the purpose of this design is to ensure unidirectional flow throughout the entire system.

[0008] Furthermore, the refrigeration compressor, refrigerant pump, and liquid receiver are integrated and installed in the pump cabinet. In practical applications, this design facilitates integration, effectively improves the ease of installation, and ensures overall installation quality.

[0009] Furthermore, the air-cooled condenser is installed outdoors and close to the pump cabinet.

Detailed Implementation

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] In this embodiment:

[0027] This embodiment proposes a liquid-cooled distribution unit based on phase change cooling, which can improve heat exchange efficiency and save water resources.

[0028] like Figures 1-5 As shown: This utility model provides a liquid-cooled distribution unit based on phase change cooling, including: an outdoor unit 1, a pump cabinet 2, pipes 3, and an indoor unit 4; the outdoor unit 1, pump cabinet 2, and indoor unit 4 are sequentially connected and communicate with each other through the pipes 3; wherein the outdoor unit 1 includes an air-cooled condenser 11; wherein the air-cooled condenser 11 includes a fan 111 and a finned coil condenser 112; the pump cabinet 2 includes a refrigeration compressor 21, a refrigerant pump 22, and a liquid storage tank 23; one end of the finned coil condenser 112 is connected to the refrigeration compressor... Unit 21 is connected to the liquid coolant; the other end of the finned coil condenser 112 is connected to the liquid storage tank 23; the liquid storage tank 23 is connected to the refrigerant pump 22; the indoor unit 4 includes a primary circulation pipe 413, a heat exchanger 42, a secondary circulation pipe 433, and a secondary circulation pump 44; the indoor unit 4 is used for liquid cooling distribution; one side of the heat exchanger 42 is connected to the primary circulation pipe 413; the secondary circulation pipe 433 is located on the other side of the heat exchanger 42 and is connected to the secondary circulation pump 44. Using Freon refrigerant instead of water (or solution) results in high heat transfer efficiency and effectively reduces energy consumption. The heat exchanger 42 in the indoor unit 4 (cooling distribution unit) is a water / fluorine heat exchanger 42, which is different from a conventional water / water heat exchanger 42, in which Freon undergoes a phase change. The refrigerant circulation system is equipped with a compressor, a refrigerant pump 22, and a one-way valve 5. Depending on the outdoor environmental conditions, different delivery equipment (compressor or refrigerant pump 22) can be activated to reduce energy consumption. The equipment does not consume water resources during operation.

[0029] In this embodiment, a one-way valve 5 is also included, which is installed on the pipeline 3. In practical applications, the purpose of this design is to ensure unidirectional flow throughout the entire system.

[0030] In this embodiment, the refrigeration compressor 21, refrigerant pump 22, and liquid receiver 23 are integrated and installed in the pump cabinet 2. In practical applications, this design facilitates integration, effectively improves the ease of installation, and ensures overall installation.

[0031] In this embodiment, the air-cooled condenser 11 is installed outdoors and close to the pump cabinet 2.

[0032] In this embodiment, the pipe 3 is a copper pipe. In practical applications, this material has a long service life and good heat exchange effect.

[0033] In this embodiment, the pipeline 3 further includes a liquid outlet pipe 31 and an air inlet pipe 32. In practical applications, this method facilitates heat transfer.

[0034] In practical applications, the refrigerant cycle of this invention has two operating modes, which are mainly selected based on outdoor environmental conditions.

[0035] The first mode: starting the refrigerant pump 22 and the air-cooled condenser 11 will drive the refrigerant circulation;

[0036] The second mode involves starting the refrigeration compressor 21, the refrigerant pump 22, and the air-cooled condenser 11 to drive the refrigerant circulation.

[0037] In actual operation, when the outdoor temperature is too high, similar to hot summer weather, the second mode can be activated to increase the compressor and lower the temperature; when the outdoor temperature is too low, the refrigerant pump 22 and the air-cooled condenser 11 can be directly started to drive the refrigerant circulation; in this way, energy loss can be effectively reduced.

[0038] In summary, this liquid-cooled distribution unit based on phase change cooling achieves high heat exchange efficiency by using Freon refrigerant instead of cryogenic water or other coolants, resulting in a phase change during circulation. Furthermore, it can switch modes according to outdoor temperature, effectively reducing energy consumption during spring, autumn, and winter. It also does not consume water resources during operation. Therefore, this device is suitable for industry-wide adoption.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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 or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
