Description

Technical Field

[0001] This utility model relates to the field of immersion liquid cooling technology, and in particular to a cooling system that combines immersion liquid cooling and outdoor unit dual-mode heat dissipation. Background Technology

[0002] Most existing immersion liquid cooling systems are single-phase immersion systems, where the liquid remains in a liquid state and heat is transferred to an external heat exchanger through natural convection or pump-driven circulation. However, the external heat exchanger has limited heat dissipation efficiency and is insufficient for cooling under high loads, resulting in a rapid rise in coolant temperature and poor heat dissipation. Utility Model Content

[0003] To address the aforementioned technical problems, an immersion liquid cooling system is provided, which solves the issues of insufficient coolant heat dissipation efficiency and low outdoor unit heat dissipation redundancy under high power conditions.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an immersion liquid cooling system, comprising,

[0005] The cooling box unit includes a cooling box body with an internal placement cavity; the cooling box body is also provided with a coolant circulation pipeline, which extends to the outside of the cooling box body.

[0006] The outdoor unit heat dissipation unit includes a radiator body. All the coolant circulation pipes are connected to the radiator body. The outlet pipes input high-temperature coolant into the radiator body. After heat dissipation, the coolant circulates into the cooling tank body through the coolant circulation pipes to cool the placement cavity. The radiator body is also provided with a heat dissipation structure and a secondary cooling structure arranged opposite to each other.

[0007] The control system controls the operation between the cooling box unit and the outdoor unit's heat dissipation unit.

[0008] According to this utility model, the coolant circulation pipeline includes a circulation pump, and the circulation pump is connected to an inlet pipeline and an outlet pipeline. One end of the inlet pipeline and the outlet pipeline extends to the outside of the cooling box body and communicates with the radiator body.

[0009] According to this utility model, the heat dissipation structure further includes at least one fan.

[0010] According to this utility model, the heat dissipation structure is further described as a fan assembly.

[0011] According to this utility model, the secondary cooling structure is a spray pipe, one end of which is connected to an external water source. The spray pipe is arranged horizontally and has an atomizing nozzle on it.

[0012] According to this utility model, the secondary cooling structure is a spray pipe, one end of which is connected to an external water source. The spray pipe is vertically arranged and has an atomizing nozzle on it.

[0013] According to this utility model, further, there are multiple atomizing nozzles, which are arranged at equal intervals along the length of the spray pipe.

[0014] According to this utility model, the temperature threshold setting of the radiator body is further defined as follows: Level 1 start (>40℃), 50% fan power is turned on; Level 2 start (>45℃), the spray pipe and 100% fan power are turned on simultaneously.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention improves heat exchange efficiency by adding a spray pipe to the radiator body and combining it with a fan. The spray water film evaporates and absorbs heat, which is combined with the forced air cooling of the fan in a dual-mode heat dissipation.

[0017] This invention completely immerses the component to be cooled in an insulating coolant, completely isolating it from air and moisture, thus improving the safety of the component. The coolant has higher thermal conductivity and specific heat capacity, enabling it to quickly and fully absorb and conduct the heat generated by the component to be cooled. This allows for direct, rapid, and thorough cooling of the component, ensuring it operates within its optimal temperature range, extending its service life, and reducing replacement costs.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] like Figures 1 to 4 As shown in the illustration, this application discloses an immersion liquid cooling system, including a cooling tank unit 100, an outdoor unit heat dissipation unit 200 connected to the cooling tank unit 100 via a circulation pipeline, and a control system. The element to be cooled is placed inside the cooling tank unit 100. Coolant is supplied to the cooling tank unit 100 via the circulation pipeline between the cooling tank unit 100 and the outdoor unit heat dissipation unit 200, thereby lowering the temperature of the element placed inside the cooling tank unit 100. The control system controls the operation between the cooling tank unit and the outdoor unit heat dissipation unit, which is prior art and will not be described further here.

[0027] Specifically, the cooling box unit 100 includes a cooling box body 110, which has a placement cavity 111 for placing components to be cooled. The cooling box body 110 also includes a circulation pump 112 connected to an inlet pipe 1121 and an outlet pipe 1122. Both the inlet and outlet pipes extend to the outside of the cooling box body 110 and communicate with the outdoor unit heat dissipation unit 200, forming a coolant circulation. Cooled liquid is injected into the cooling box body 110 to cool the electronic components. The heated liquid is discharged through the outlet pipe 1122 to the outdoor unit heat dissipation unit 200, where it is cooled before circulating back to the inlet pipe 1121, achieving coolant cooling and recycling while improving the cooling effect of the cooling box body 110. The components to be cooled can be batteries or servers.

[0028] The outdoor unit cooling unit 200 includes a radiator body 210. A fan assembly 211 is installed on one side of the radiator body 210, and a spray pipe 220 is installed on the other side of the radiator body 210. One end of the spray pipe 220 is connected to a water supply end, and water is sprayed onto the radiator body 210 to accelerate cooling. The spray pipe 220 can be installed horizontally or vertically, and multiple atomizing nozzles are evenly spaced along its length to increase the spray range and improve the cooling speed.

[0029] In this embodiment of the application, a water receiving tray (not shown in the figure) is provided below the radiator body 210. The position of the water receiving tray corresponds to the position of the spray pipe 220 and is used to catch the water falling from the spray pipe 220 to prevent the water from flowing to the ground and causing the ground to become muddy.

[0030] Example 1

[0031] The cooling box body 110 is made of steel plate welded into shape, and the cooling element placement cavity 111 accommodates the server to be cooled; the coolant is a hydrocarbon compound with a boiling point >330℃; an atomizing nozzle is installed on the spray pipe 220 at intervals of 12-18cm, and the water supply pressure is 0.2MPa.

[0032] The 210 radiator body uses aluminum finned tubes with a surface area ≥8㎡ / kW; temperature threshold settings: Level 1 start (>40℃), 50% fan power is activated; Level 2 start (>45℃): both spray pipes and 100% fan power are activated simultaneously. These settings can also be customized, and the fan will automatically adjust its speed based on the temperature level to reduce the PUE value.

[0033] Example 2

[0034] like Figure 5 and Figure 6 As shown, the cooling box body 110 is a cuboid, the circulation pump 112 is located on one side of the placement cavity 111, the radiator body 210 is equipped with a fan, and the other side of the radiator body 210 is equipped with a horizontally arranged spray pipe 220.

[0035] Example 3

[0036] The cooling box body 110 is a horizontal cuboid. The circulation pump 112 is located on one side of the placement cavity 111. The radiator body 210 is equipped with a fan assembly 211. The other side of the radiator body 210 is equipped with a vertically arranged spray pipe 220.
