Description

Technical Field

[0001] This utility model relates to the field of liquid cooling technology, and in particular to a waste heat recovery liquid cooling system. Background Technology

[0002] Liquid cooling technology utilizes liquid media (such as water, mineral oil, fluorinated liquids, etc.) and is widely used in high-power-density scenarios (such as data center servers, AI chips, electric vehicle batteries, etc.). However, the waste heat recovery temperature of liquid cooling systems is usually low (e.g., the outlet temperature of immersion liquid cooling is about 30-45℃, and that of cold plate liquid cooling is about 40-50℃), making it difficult to apply to high-value-added scenarios (such as power generation, industrial heating, etc.). The scenarios for waste heat recovery and utilization are relatively limited and the returns are low. Moreover, the complex overall structure of existing waste heat recovery technologies leads to high costs for waste heat recovery, which greatly affects the promotion of waste heat recovery during the use of liquid cooling equipment and is not conducive to energy conservation and environmental protection. Utility Model Content

[0003] This invention provides a waste heat recovery liquid cooling system, which not only reduces the cost of waste heat recovery but also has the characteristics of energy saving and environmental protection.

[0026] The liquid cooling device 100 includes a liquid cooling container 10 and a heating element 50. A sealed space is formed inside the liquid cooling container 10, and a heat transfer medium is disposed in the sealed space. The heating element 50 is immersed in the heat transfer medium. A first heat exchange surface 1012 and a second heat exchange surface 1011 are formed on the liquid cooling container 10. The first heat exchange surface 1012 is located on one side of the sealed space so that the first heat exchange surface 1012 can exchange heat with the heat transfer medium. The liquid cooling device 100 is disposed in the receiving space 701 so that the second heat exchange surface 1011 is in contact with the waste heat recovery medium. The first heat exchange surface 1012 and the second heat exchange surface 1011 are thermally coupled.

[0027] In this embodiment, thermal coupling refers to the ability to transfer heat between each other in any way.

[0028] This embodiment provides a waste heat recovery liquid cooling system, which includes a waste heat recovery tank 70 and a liquid cooling device 100. The liquid cooling device 100 includes at least a liquid cooling container 10 and a heating element 50. The liquid cooling container 10 is located in a sealed space, in which a heat transfer medium and a heating element 50 are disposed. The liquid cooling container 10 is placed in the receiving space 701 of the waste heat recovery tank 70. When the heating element 50 is working, the heat it generates is directly transferred to the heat transfer medium. The heat transfer medium exchanges heat with the first heat exchange surface 1012, which then transfers the heat to the second heat exchange surface 1011. Since the second heat exchange surface 1011 is in contact with the waste heat recovery medium, the heat is finally transferred to the waste heat recovery medium, which can maintain the waste heat recovery medium at a set temperature. The waste heat recovery medium can be utilized in daily life, such as in fish farming. It not only has a simple overall liquid cooling structure, but also a simple waste heat recovery structure. In addition, it is more energy-efficient and environmentally friendly.

[0029] In a further embodiment of this invention, the waste heat recovery tank 70 is a fish tank, and the waste heat recovery working medium is water used for raising fish.

The top of the container body 102 has a container opening 1021. The container cover 101 covers the container opening 1021 on the top of the container body 102. A sealed connection is formed between the container cover 101 and the container body 102 to form a sealed space inside the container body 102. The first heat exchange surface 1012 and the second heat exchange surface 1011 are the upper and lower surfaces of the container cover 101, respectively. The container cover 101 is made of metal. The waste heat recovery working fluid is immersed in the liquid-cooled container 10.

[0032] In a further embodiment of this invention, the heat transfer medium is a two-phase heat transfer medium.

[0033] In this embodiment, when the heating element 50 is working, the two-phase heat transfer medium vaporizes and rises to contact the first heat exchange surface 1012. After the medium condenses, it drips back down or flows back along the inner wall of the container body 102. In this embodiment, the two-phase heat transfer medium can be used for heat exchange in the latent heat mode, which can quickly remove the heat generated by the heating element 50.

[0034] Specifically, in this embodiment, a sealing groove 1022 is provided on the top of the container body 102, and a sealing ring 40 is provided in the sealing groove 1022.

[0040] In this embodiment, the heating element 50 is a computer motherboard module, which can be combined with a home PC. Specifically, in this embodiment, a home pet fish tank can be combined with a home PC, which can be more conducive to promotion and expansion of home use scenarios.

[0041] In a further embodiment of this invention, a connector component 20 is provided on the container cover 101. The connector component 20 extends into the sealed space, and a sealed connection is formed between the connector component 20 and the container cover 101. An electrical connector 201 is formed at one end of the connector component 20 that extends into the sealed space. An electrical connector 80 is provided on the computer motherboard module. The electrical connector 80 and the electrical connector 201 are plugged into each other to make the computer motherboard module electrically connected to the connector component 20.
