Description

Technical Field

[0001] This utility model relates to the field of liquid cooling technology, and in particular to a novel high-efficiency condensation device. Background Technology

[0002] In the field of data center technology, with the increase in computing power and power of servers, the heat flux density of servers has also increased accordingly. Traditional air cooling technology can no longer meet the current heat dissipation requirements of servers. Therefore, existing technologies generally use liquid cooling to dissipate heat from servers with high heat flux density, depending on whether the liquid can undergo phase change. Liquid cooling can be divided into single-phase liquid cooling and two-phase liquid cooling. The significant advantage of two-phase liquid cooling is that the heat absorbed by liquid evaporation is much greater than the heat absorbed by liquid temperature rise alone. This means that under the same liquid flow rate, the two-phase system can remove much more heat than the single-phase system. Therefore, in servers with high heat flux density, a two-phase working fluid can be filled into the cold head. The contact area inside the cold head is increased by a spade-like structure. The cold head and the heating element form a thermal coupling. The heat from the heating element is transferred to the cold head. After the cold head heats up, the two-phase working fluid undergoes a phase change and absorbs heat. The gaseous working fluid condenses and flows back into the cold head. However, during the condensation process of the gaseous working fluid, its flow rate determines its heat exchange efficiency, and thus the condensation efficiency. Utility Model Content

Detailed Implementation

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See Figure 1 and Figure 2 This utility model provides a novel high-efficiency condensation device, comprising:

[0024] The device housing 10 has an internal accommodating space and a first channel 100 and a second channel 80 formed on the device housing 10.

[0025] The heat dissipation structure 30 forms a thermal coupling with the top of the device housing 10;

[0026] Effect component 20, multiple effect components 20 are disposed in the receiving space, effect component 20 has a preset height at least in the vertical direction, each effect component 20 has an ascending channel 140 formed thereon, ascending channel 140 has at least an inlet end 70 and an outlet end 40, the outlet end 40 is located above the inlet end 70, there is a first preset space 120 between the outlet end 40 and the top of the receiving space, there is a second preset space 130 between the inlet end 70 and the bottom of the receiving space, the first channel 100 and the second channel 80 are connected to the second preset space 130.

[0027] This embodiment provides a novel high-efficiency condensation device, which includes a device housing 10, a heat dissipation structure 30, and an effect component 20. The heat dissipation structure 30 is disposed at the top of the device housing 10, while the effect component 20 is disposed in the accommodating space inside the device housing 10. The gaseous working fluid enters the second preset space 130 from the first channel 100. Due to the formation of an upward channel 140 in the effect component 20, and under the action of the top heat dissipation structure 30, a temperature difference effect is formed below and below the effect component 20. Under the action of the temperature difference effect, the gas... The working fluid enters from the inlet at the inlet end 70 and rises rapidly along the rising channel 140. During the rise, part of the gaseous working fluid condenses and flows back to the second preset space 130, while most of the gaseous working fluid enters the first preset space 120 from the outlet at the outlet end 40. The gaseous working fluid exchanges heat with the top surface of the first preset space 120 and condenses to form liquid working fluid in the form of droplets. Then, it flows back to the second preset space 130 from the rising channel 140 and is discharged through the second channel 80 for the next heat exchange cycle.

[0028] The heat dissipation structure 30 in this embodiment can be any structure in the prior art that can achieve heat dissipation, such as an air-cooled heat dissipation structure.

[0029] In a further embodiment of this example, the ascending channel 140 is a variable cross-section channel, the outlet end 40 is a small-size end, and the inlet end 70 is a large-size end.

[0030] In this embodiment, the rising channel 140 adopts a variable cross-section channel with a structure that is narrow at the top and wide at the bottom, which can accelerate the rising speed of the gaseous working fluid and thus improve its condensation efficiency.

[0031] In addition, the ascending channel 140 in this embodiment can be a conical channel.

[0032] In a further embodiment of this example, the first channel 100 is higher than the second channel 80.

[0033] In this embodiment, the first channel 100 being higher than the second channel 80 ensures that the gaseous working fluid entering the second preset space 130 rises upwards.

[0034] In a further embodiment of this invention, the novel high-efficiency condensation device further includes a lower sealing plate 150, which is connected to the inlet end 70 of the effect component 20. A lower connection port is formed on the lower sealing plate 150, and the lower connection port is correspondingly arranged with the inlet of the inlet end 70. The lower sealing plate 150 is connected to the inner wall of the accommodating space.

[0035] In this embodiment, the lower sealing plate 150 serves two purposes: firstly, it enables the installation of the effect component 20, thereby suspending the effect component 20 in a suspended state; secondly, it effectively prevents the gaseous working medium from climbing upwards in the space between the effect component 20 and the gaseous working medium, ensuring that the gaseous working medium can only enter from the inlet of the inlet end 70.

[0036] In a further embodiment of this invention, multiple effect components 20 are arranged in a rectangular array within the accommodating space.

[0037] In a further embodiment of this invention, the novel high-efficiency condensation device also includes an upper sealing plate 60, which is connected to the outlet end 40. An upper connection port is formed on the upper sealing plate 60, and the upper connection port is correspondingly arranged with the outlet of the outlet end 40. The upper sealing plate 60 is connected to the inner wall of the accommodating space.

[0038] In this embodiment, the upper sealing plate 60 is used to install and connect the effect component 20.

[0039] In a further embodiment of this invention, an upper guide slope 50 is formed on the upper surface of the upper sealing plate 60 and around the outlet end 40.

[0040] In this embodiment, the upper guide slope 50 can gather the droplet-shaped liquid working fluid that drips onto the upper sealing plate 60 to the outlet end 40.

[0041] In a further embodiment of this invention, the novel high-efficiency condensation device also includes a rib structure 110, through which multiple effect components 20 are connected, and the rib structure 110 is connected to the inner wall of the accommodating space.

[0042] In this embodiment, the rib structure 110 not only facilitates the installation and connection of the effect components 20, but also improves the temperature uniformity among the effect components 20.

[0043] In a further embodiment of this invention, the first channel 100 is disposed on the side wall of the device housing 10, and the second channel 80 is disposed at the bottom of the device housing 10.

[0044] In a further embodiment of this invention, a lower guide slope 90 is formed on the bottom surface of the accommodating space and around the second channel 80.

[0045] In this embodiment, the lower guide slope 90 can facilitate the flow of liquid working fluid from the second preset space 130 to the second channel 80.
