Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling and heat dissipation equipment, in particular to an immersion type liquid cooling and heat dissipation system device. Background Art

[0002] With the rapid development of applications such as big data, cloud computing, smart cities, mobile Internet and the Internet of Things, the performance requirements for electronic information equipment are getting higher and higher. Performance improvement will inevitably lead to a significant increase in the heat generation and heat flux density of electronic components. If the heat generated by electronic components during operation is not removed in time, the internal temperature of these components will rise rapidly. The reliability of electronic components is very sensitive to temperature, which poses a severe challenge to traditional inefficient air cooling technology. Therefore, liquid cooling technology has gradually become a hot research topic in heat dissipation technology for high-density electronic information equipment.

[0003] In existing single-phase immersion liquid cooling applications, the heat dissipation side is generally any one of an air cooler, cooling tower, heat exchanger, and air conditioner outdoor unit. In a high-temperature outdoor environment, the air cooler and cooling tower have limited heat dissipation and cannot reduce the coolant temperature, resulting in poor heat dissipation of the server and causing server downtime. At the same time, the primary side liquid cooling uses a cooling tower or refrigerator for cooling, which is difficult to apply in water-free or water-scarce scenarios. In addition, the initial investment cost increases and the operation and maintenance is complicated. When a heat exchanger or air conditioner outdoor unit is used in a low-temperature outdoor environment, a natural cold source cannot be used to reduce the unit's PUE value.

[0022] The refrigeration cycle is connected to a heat dissipation component for dissipating heat for the second immersion liquid cooling cabinet 14 and the first immersion liquid cooling cabinet 9; the heat dissipation component includes a first electronic coolant pipeline 7, a liquid cooling pump 10, a three-way valve 11, a fifth electronic coolant pipeline 15, a filter 8, a second electronic coolant pipeline 12 and a third electronic coolant pipeline 13; the liquid cooling pump 10, the three-way valve 11, the condensation cooling coil assembly 2, the heat exchanger 5, the filter 8, the second immersion liquid cooling cabinet 14 and the first immersion liquid cooling cabinet 9 are connected through the first electronic coolant pipeline 7, the fifth electronic coolant pipeline 15, the second electronic coolant pipeline 12 and the third electronic coolant pipeline 13 to form an electronic coolant circulation system; a compressor is used for refrigeration in a high temperature environment, the electronic coolant is cooled by a heat exchanger, and a cooling coil is used to cool the electronic coolant in a low temperature environment, thereby reducing energy consumption and improving energy utilization efficiency.

[0023] The liquid cooling pump 10 and the three-way valve 11 are connected in series to the first electronic coolant pipeline 7, one end of the second electronic coolant pipeline 12 is connected to the third connection port of the three-way valve 11, and the other end of the second electronic coolant pipeline 12 is communicated with the fifth electronic coolant pipeline 15, and the filter 8 is connected in series to the fifth electronic coolant pipeline 15, and one end of the first electronic coolant pipeline 7 and the fifth electronic coolant pipeline 15 away from the electronic coolant coil on the condensing cooling coil assembly 2 is respectively connected to the inlet and outlet connection ports of the second immersion liquid cooling cabinet 14, and the inlet and outlet connection ports of the first immersion liquid cooling cabinet 9 are respectively connected to the third electronic coolant pipeline 13, and the two third electronic coolant pipelines 13 are respectively connected to the first electronic coolant pipeline 7 and the fifth electronic coolant pipeline 15; when working, the liquid cooling pump 10 starts to drive the electronic coolant to circulate in the pipeline, the filter 8 can filter the impurities in the electronic coolant, and the three-way valve 11 can be used to change the flow direction of the electronic coolant.
