Description

Technical Field

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

[0002] As data centers evolve towards higher power densities, traditional air cooling methods are no longer sufficient to meet their heat dissipation needs. To address these demands, immersion liquid cooling systems have emerged as a design approach for data center heat dissipation.

[0003] Currently, most immersion liquid cooling systems place the heat source in a large tank filled with coolant. The coolant flows in the tank without undergoing a phase change, and only generates heat through convection with the heat source. This type of heat dissipation requires a large amount of coolant, has a high cost, and is not very effective. 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 container with simple structural design, low coolant demand, excellent heat dissipation effect and accurate coolant level measurement.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: an immersion liquid-cooled phase change container, comprising a container body, a water-cooling system installed on one side of the container body, and a condensing chamber, a condenser, and a storage tank installed inside the container body; the condensing chamber stores coolant for absorbing heat from a heat source; the condenser and the storage tank are both located outside the condensing chamber; the air outlet of the condensing chamber is connected to the air inlet of the condenser through an air outlet pipe, and its liquid inlet is connected to the liquid outlet of the storage tank through a liquid inlet pipe; the liquid outlet of the condenser is connected to the liquid inlet of the storage tank through an liquid outlet pipe; one end of the water-cooling system is connected to the water inlet of the condenser, and the other end is connected to the water outlet of the condenser; the coolant in the condenser exchanges heat with the cooling water.

[0006] Furthermore, it also includes a liquid level measuring cylinder installed on the other side of the housing, the liquid level measuring cylinder being equipped with a liquid level gauge; the upper part of the liquid level measuring cylinder is connected to the upper part of the condensing chamber, and the lower part of the liquid level measuring cylinder is connected to the lower part of the condensing chamber.

[0007] Furthermore, the water cooling system includes a water cooler, a water tank, an inlet pipe, and an outlet pipe; the water cooler is installed on one side of the housing; the water inlet of the water cooler is connected to the outlet of the condenser through the inlet pipe, and its outlet is connected to the inlet of the condenser through the outlet pipe; the water tank is installed on the top of the water cooler and is connected to the water cooler.

[0008] Furthermore, a gas flow meter is installed on the gas outlet pipe.

[0009] Furthermore, an inlet pump is installed on the inlet pipeline.

[0010] Furthermore, a water pump is installed on the water outlet pipeline.

[0011] Furthermore, a water flow meter is installed on the water inlet pipe.

[0012] Furthermore, an exhaust port is provided at the top of the condensation chamber.

[0013] Furthermore, the top cover of the enclosure is equipped with a glass window, which is positioned opposite to the condensation chamber.

[0014] Furthermore, rollers are installed at the four corners of the bottom plate of the box.

[0015] The beneficial effects of this invention are:

[0016] (1) The present invention absorbs heat from the heat source through the coolant in the condenser chamber. After the coolant reaches the boiling point, it changes phase to gaseous state. The gaseous coolant enters the condenser and exchanges heat with the cooling water in the condenser. Due to the turbulence in the condenser, the gaseous coolant quickly changes phase back to liquid state. The liquid coolant flows into the storage tank for storage. The liquid coolant in the storage tank finally flows back to the condenser chamber to form a cycle, thereby realizing the recycling of coolant, reducing the demand for coolant, reducing the cost of using coolant, and significantly improving the heat dissipation effect.

[0017] (2) By setting up a liquid level measuring cylinder, the coolant in the condensing chamber is introduced into the liquid level measuring cylinder for measurement, which avoids the adverse effects of the liquid level fluctuation caused by the boiling of the coolant in the condensing chamber, thereby realizing accurate measurement of the liquid level.

Detailed Implementation

[0026] 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.

[0027] like Figures 1-3 As shown, an immersion liquid-cooled phase change container includes a container body 100, a water-cooling system 200 installed on one side of the container body 100, and a condensing chamber 300, a condenser 400, and a storage tank 500 installed inside the container body 100. The condensing chamber 300 stores coolant for absorbing heat from a heat source. The condenser 400 and the storage tank 500 are both located outside the condensing chamber 300. The air outlet of the condensing chamber 300 is connected to the air inlet of the condenser 400 via an air outlet pipe 600, and its liquid inlet is connected to the liquid outlet of the storage tank 500 via a liquid inlet pipe 700. The liquid outlet of the condenser 400 is connected to the liquid inlet of the storage tank 500 via a liquid outlet pipe 800. One end of the water-cooling system 200 is connected to the water inlet of the condenser 400, and the other end is connected to the water outlet of the condenser 400. The coolant in the condenser 400 exchanges heat with the cooling water.

[0028] The coolant in the condenser 300 absorbs heat from the heat source. After reaching its boiling point, the coolant changes phase to gas. The gaseous coolant enters the condenser 400 and exchanges heat with the cooling water inside the condenser 400. Due to the turbulence inside the condenser 400, the gaseous coolant quickly changes phase back to liquid. The liquid coolant flows into the storage tank 500 for storage. Finally, the liquid coolant in the storage tank 500 flows back to the condenser 300 to form a cycle, thus realizing the recycling of coolant, reducing the demand for coolant, reducing the cost of using coolant, and significantly improving the heat dissipation effect.

[0029] Specifically, the coolant used is a low-boiling-point coolant, such as fluorinated liquid; the top cover of the housing 100 is equipped with a glass window, which is positioned opposite the condenser chamber 300 to facilitate observation of the interior of the condenser chamber 300; casters are installed at the four corners of the bottom plate of the housing 100 to facilitate movement of the housing 100; an exhaust port is provided at the top of the condenser chamber 300 to remove excess air; a gas flow meter is installed on the exhaust pipe 600 to monitor the flow rate of gaseous coolant in the exhaust pipe 600 in real time; an inlet pump is installed on the inlet pipe 700 to pump the liquid coolant in the storage tank 500 back into the condenser chamber 300; a level gauge is installed on the storage tank 500 to monitor the liquid coolant level in the storage tank 500, and the inlet pump is activated when the level reaches the preset level.

[0030] like Figure 1 As shown, the submersible liquid-cooled phase change container also includes a liquid level measuring cylinder 900 installed on the other side of the container body 100. A liquid level gauge is installed inside the liquid level measuring cylinder 900. The upper part of the liquid level measuring cylinder 900 is connected to the upper part of the condensing chamber 300, and its lower part is connected to the lower part of the condensing chamber 300. By using the liquid level measuring cylinder 900, the coolant in the condensing chamber 300 is introduced into the liquid level measuring cylinder 900 for measurement, avoiding the adverse effects of liquid level fluctuations caused by boiling of the coolant in the condensing chamber 300, thus achieving accurate liquid level measurement.

[0031] like Figure 1 , Figures 4-6 As shown, the water cooling system 200 includes a water cooler 210, a water tank 220, an inlet pipe 230, and an outlet pipe 240. The water cooler 210 is installed on one side of the housing 100. The inlet of the water cooler 210 is connected to the outlet of the condenser 400 through the inlet pipe 230, and its outlet is connected to the inlet of the condenser 400 through the outlet pipe 240. The water tank 220 is installed on the top of the water cooler 210 and is connected to the water cooler 210 for replenishing water to the water cooler 210. Specifically, a water flow meter is installed on the inlet pipe 230 to detect the flow rate of cooling water in the inlet pipe 230 in real time; a water pump is installed on the outlet pipe 240 to pump the cooling water in the water cooler 210 into the condenser 400. A backup pipeline can also be installed on the water outlet pipeline 240. When the water outlet pipeline 240 fails, the backup pipeline will be activated to ensure operational stability.

[0032] It should be noted that each pipeline is equipped with a solenoid valve to control the pipeline opening and closing, which is existing technology and will not be described in detail here.

[0033] During operation, the heat source is immersed in the coolant in the condenser 300. The coolant boils and changes phase to gaseous state upon heating. As the amount of gaseous coolant in the condenser 300 increases, it is forced into the outlet pipe 600 and then into the condenser 400 without the need for a pump. The gaseous coolant in the condenser 400 exchanges heat with the cooling water. The cooling water absorbs the heat from the gaseous coolant, causing its temperature to drop rapidly and it to change phase back to liquid. The liquid coolant flows into the storage tank 500 through the outlet pipe 800 for storage, while the cooling water that has absorbed heat enters the water cooler 210. The fan on the water cooler 210 dissipates the heat from the cooling water, and the cooled water circulates back to the condenser 400. After a certain amount of liquid coolant is stored in the storage tank 500, it is pumped back into the condenser 300 through the inlet pump on the inlet pipe 700.

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.
