Description

Technical Field

[0001] This invention relates to the field of heat dissipation technology, and in particular to an immersion liquid-cooled phase change system. Background Technology

[0002] With the development of data centers and digital currencies, traditional air cooling methods can no longer meet the heat dissipation requirements of data centers. To address these requirements, immersion liquid cooling equipment has emerged on the market.

[0003] Currently, most immersion liquid cooling equipment mainly uses coil technology for coolant heat exchange. In order to ensure the heat exchange effect, the number of coils is usually designed to be large, which makes the entire equipment too bulky, resulting in a large footprint and limited heat exchange efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an immersion liquid-cooled phase change system with simple structural design, small footprint and significant heat exchange efficiency.

[0005] The technical solution adopted by this invention to solve its technical problem is: an immersion liquid-cooled phase change system, including a housing, a liquid cooling unit disposed outside the housing, and a condenser installed inside the housing. The bottom of the housing stores liquid coolant, and the condenser is disposed above the liquid coolant. The liquid cooling unit is connected to the condenser and is used to continuously inject coolant into the condenser. The condenser includes a heat exchange section for heat exchange between the coolant and the gaseous coolant. The heat exchange section has a hollow structure, and a plurality of through vertical holes are opened in the middle of the heat exchange section, which divide the interior of the heat exchange section into a plurality of transverse flow channels.

[0006] Furthermore, the condenser also includes a liquid inlet end and a liquid outlet end; the liquid inlet end and the liquid outlet end are respectively installed at both ends of the heat exchange section and are connected to several transverse flow channels inside the heat exchange section; the liquid cooling unit is connected to the liquid inlet end and the liquid outlet end respectively.

[0007] Furthermore, the liquid cooling unit includes a dry cooler, an inlet pipe, and an outlet pipe; the dry cooler is located above the housing; the inlet of the dry cooler is connected to the outlet end through the inlet pipe, and its outlet is connected to the inlet end through the outlet pipe.

[0008] Furthermore, a high-pressure pump and a first butterfly valve are installed on the inlet pipeline, and a flow meter and a second butterfly valve are installed on the outlet pipeline.

[0009] Furthermore, a level gauge is installed on one side of the box, and a vacuum breaking valve is installed on the cover plate of the box.

[0010] Furthermore, a glass window is installed on the cover of the enclosure.

[0011] Furthermore, a pressure gauge and a thermometer are installed on the enclosure.

[0012] The beneficial effects of this invention are:

[0013] This invention utilizes a condenser to exchange heat with gaseous coolant, achieving a significant reduction in size compared to heat exchange using coil technology. This simplifies the internal design of the casing and reduces the floor space required. Furthermore, the heat exchange section is divided into several transverse channels by vertical holes, allowing for extensive and thorough contact between the gaseous coolant flowing through the vertical holes and the coolant flowing through the transverse channels. This significantly improves heat exchange efficiency and ensures optimal heat exchange performance. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0023] like Figure 1 , Figures 3-5As shown, an immersion liquid-cooled phase change system includes a housing 100, a liquid cooling unit 200 disposed outside the housing 100, and a condenser 300 installed inside the housing 100. The bottom of the housing 100 stores liquid coolant, and the condenser 300 is disposed above the liquid coolant. The liquid cooling unit 200 is connected to the condenser 300 and is used to continuously inject coolant into the condenser 300. The condenser 300 includes a heat exchange section 310 for heat exchange between the coolant and the gaseous coolant. The heat exchange section 310 has a hollow structure, and a plurality of through vertical holes 311 are opened in the middle of the heat exchange section 310. The plurality of vertical holes 311 divide the interior of the heat exchange section 310 into a plurality of transverse flow channels 312.

[0024] Specifically, a low-boiling-point coolant, such as fluorinated liquid, is used as the coolant; a glass window is installed on the cover of the housing 100 to facilitate observation of the interior of the housing 100; the condenser 300 is a cuboid; several vertical holes 311 are spaced apart along the width of the heat exchange section 310; the vertical holes 311 and the transverse flow channels 312 are staggered.

[0025] By using the condenser 300 to exchange heat with the gaseous coolant, a significant reduction in size is achieved compared to using coil technology for heat exchange, simplifying the internal design of the housing 100 and thus reducing the floor space. At the same time, the interior of the heat exchange section 310 is divided into several transverse flow channels 312 by several vertical holes 311, allowing the gaseous coolant flowing through the vertical holes 311 to have a large-area and full contact with the coolant flowing through the transverse flow channels 312, thereby significantly improving the heat exchange efficiency and ensuring the heat exchange effect.

[0026] like Figure 3 and Figure 4 As shown, the condenser 300 also includes a liquid inlet end 320 and a liquid outlet end 330; the liquid inlet end 320 and the liquid outlet end 330 are respectively installed at both ends of the heat exchange section 310 and communicate with a plurality of transverse flow channels 312 inside the heat exchange section 310; the liquid cooling unit 200 is communicated with the liquid inlet end 320 and the liquid outlet end 330 respectively. Specifically, both the liquid inlet end 320 and the liquid outlet end 330 have cavities inside, and the liquid cooling unit 200 communicates with the plurality of transverse flow channels 312 through the cavities.

[0027] like Figure 1 As shown, the liquid cooling unit 200 includes a cooler 210, an inlet pipe 220, and an outlet pipe 230. The cooler 210 is positioned above the housing 100. The inlet of the cooler 210 is connected to the outlet 330 via the inlet pipe 220, and its outlet is connected to the inlet 320 via the outlet pipe 230. Specifically, a fan on the cooler 210 is used to cool the coolant inside the cooler 210. A high-pressure pump and a first butterfly valve are installed on the inlet pipe 220, and a flow meter and a second butterfly valve are installed on the outlet pipe 230.

[0028] like Figure 2 As shown, a level gauge 400 is installed on one side of the tank 100 to monitor the liquid coolant level inside the tank 100 in real time. A vacuum breaking valve 500 is installed on the cover plate of the tank 100 to draw in air when there is negative pressure.

[0029] To monitor the pressure and temperature inside the housing 100 in real time, a pressure gauge and a thermometer are also installed on the housing 100. To collect the discharged gaseous coolant, a liquid storage tank 600 is installed on one side of the housing 100, and the liquid storage tank 600 is connected to the upper part of the housing 100.

[0030] During operation, the heat source is immersed in the liquid coolant at the bottom of the housing 100. The liquid coolant boils and changes phase to gaseous state when heated. The gaseous coolant gradually rises and enters several vertical holes 311 in the condenser 300. At this time, the cooled coolant flows through several horizontal channels 312. The gaseous coolant in the vertical holes 311 exchanges heat with the coolant in the horizontal channels 312. The coolant carries away the heat of the gaseous coolant, and the temperature of the gaseous coolant drops rapidly and changes phase back to liquid state. The liquid coolant falls back to the bottom of the housing 100, while the coolant that has absorbed heat enters the liquid cooling unit 200 for cooling. The cooled coolant is then circulated back to the condenser 300 to continue heat exchange.

[0031] In practical applications, this system can employ multiple arrays arranged within a frame, such as... Figure 6 As shown.

[0032] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
