[0025] Refer to Figures 1 to 5As shown in the figure, the utility model provides an integrated phase change immersion liquid cooling device, including: a base 1, a condensing pipe 2, a heat exchanger 3, and a cooling fan 4.

[0026] A receiving box 11 is installed on the base 1. An insulating refrigerant for cooling electronic devices is filled in the receiving box 11. The base 1 is used for integrally installing the receiving box, the heat exchanger, and the cooling fan.

[0027] In this embodiment, the base is rectangular.

[0028] As a preferred embodiment, the base 1 is a mobile base. Specifically, universal wheels are respectively installed at the four corners of the base.

[0029] The condensing pipe 2 is arranged at the upper part inside the receiving box 11. The condensing pipe 2 is used for containing a coolant. The condensing pipe 2 is fixedly installed in the upper space inside the receiving box. The coolant contained in the cooling pipe is water, ethylene glycol, or propylene glycol solution.

[0030] As a preferred embodiment, the condensing pipe 2 is a condensing coil.

[0031] In this embodiment, the condensing coil is in an S shape, a concentric rectangle, a concentric square, or a concentric circle.

[0032] The heat exchanger 3 is installed outside the receiving box 11. The heat exchanger 3 is connected to the condensing pipe 2 through a conveying pipeline 31.

[0033] As a preferred embodiment, the heat exchanger 3 is a tube-fin heat exchanger or a plate-fin heat exchanger.

[0034] The cooling fan 4 is installed on the base 1. The cooling fan 4 is aligned with the heat exchanger 3.

[0035] In this embodiment, a protective plate 12 is formed by turning up the outer edge of the base 1. The protective plate 12 is arranged in a circle along the circumferential direction of the base 1. A cover plate 13 is installed at the upper opening of the protective plate 12. The protective plate 12 is provided with an air outlet. The air outlet is aligned with the cooling fan 4. The air outlet is arranged at the rear side of the base. The cooling fan cools the heat of the heat exchanger through air cooling.

[0036] The cover plate 13 is detachably connected to the protective plate 12 through a buckle 14.

[0037] The integrated phase change immersion liquid cooling device of the utility model solves the problems that the heat dissipation systems of computing servers and workstations have high energy consumption, the computing power of workstations is improved, the system thermal power consumption increases sharply, and the traditional air cooling or cold plate liquid cooling heat dissipation faces severe challenges.

[0038] The integrated phase change immersion liquid cooling device of the utility model integrally installs the receiving box, the heat exchanger, and the cooling fan on the base, which requires a small space, occupies a small area, and is convenient for layout and movement.

[0039] The integrated phase change immersion liquid cooling device of the utility model is composed of a chassis through a base, a protective plate and a cover plate, and a container box is used as an inner tank. A condenser, an exhaust valve, a liquid level gauge and a pressure regulating valve are installed in the container box. The heat exchanger is connected to the condenser through a delivery pipeline. The delivery pipeline is connected to a delivery pump 32.

[0040] In this embodiment, the insulating refrigerant is selected from electronic fluorinated liquid, mineral oil or other insulating fluid media. The insulating refrigerant is filled in a container inside the chassis. The container is not completely filled, and a space of 10 to 50 cm is left on the top. After the surfaces of electronic components such as boards and power supplies are treated with "three protections", they are immersed in the insulating refrigerant in the container. The heat generated by the electronic components is transferred to the insulating refrigerant. After absorbing heat, the insulating refrigerant undergoes a phase change and boils, and the liquid working medium inside the insulating refrigerant is transformed into small bubbles. The bubbles rise to the vapor-liquid surface under the action of buoyancy, and burst at the vapor-liquid surface. The steam diffuses to the condenser and condenses on the outside of the condensing coil, transferring the heat to the condenser. The condenser transfers the heat to the internal coolant (such as water), and the coolant carries the heat to the heat exchanger, and the heat is transferred to the atmospheric environment through the convection heat exchange of the air flow between the heat exchanger and the air blown by the cooling fan.

[0041] In this embodiment, the delivery pump, heat exchanger, delivery pipeline and cooling fan are used as the primary heat exchange system. The storage box and condensing coil are used as the secondary heat exchange system. Integrating the primary heat exchange system and the secondary heat exchange system into one device can effectively reduce the system volume and facilitate installation and transportation.

[0042] The specific implementation steps of the integrated phase change immersion liquid cooling device of the utility model are as follows:

[0043] a. Install the containing box inside the chassis and weld them into one piece.

[0044] b. The condensing coil is installed on the upper part of the containing box.

[0045] c. Connect the heat exchanger to the condensing coil, pump, etc.

[0046] d. Assemble the testing components in the container, such as pressure gauge, exhaust valve, safety valve, liquid level gauge, sealing strip, etc.

[0047] e. Install power supply lines;

[0048] f. Install motherboards / servers and other electronic components.

[0049] g. Inject the insulating refrigerant into the container.

[0050] h. Inject coolant into the heat exchanger.

[0051] The integrated phase change immersion liquid cooling device of the present utility model transfers heat by means of immersion phase change heat transfer. Compared with air cooling or cold plate liquid cooling, the heat dissipation efficiency can be improved by 1 to 2 orders of magnitude, which can effectively improve the heat dissipation performance of edge computing servers, workstations and small data rooms, reduce the heat dissipation energy consumption of workstations, and achieve the purpose of efficient heat dissipation, energy conservation and emission reduction. At the same time, the integrated design can reduce the equipment installation space and facilitate the layout and movement in a limited space.
