Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to an evaporator for data center cooling. Background Technology

[0002] In recent years, with the continuous development of artificial intelligence, 5G base stations, and the Internet of Things, and against the backdrop of the steady progress of the national new infrastructure construction, the demand for rapid data processing has been rising, leading to the vigorous development of the data center industry. This has brought about the problem of high energy consumption in data centers and also posed new challenges to data center cooling systems.

[0003] A search revealed existing technology (publication number: CN221463984U), which describes "an air conditioning unit for data centers combining spray-type evaporative condensation and integrated heat pipes, comprising a unit casing, which is horizontally divided into an indoor side air duct and an outdoor side air duct by a partition; the front side wall of the unit casing corresponding to the indoor side air duct is provided with a return air inlet, and the rear side wall is provided with a supply air inlet, with a heat pipe evaporator, a mechanical refrigeration evaporator, and an indoor fan arranged sequentially between the return air inlet and the supply air inlet along the airflow direction; the front side wall of the unit casing corresponding to the outdoor side air duct is provided with an air outlet, and the rear side wall of the unit casing corresponding to the outdoor side air duct is provided with an outdoor fresh air inlet, with a spray cooling system, a heat pipe condenser, a mechanical refrigeration condenser, a compressor, an oil separator, and an outdoor fan arranged sequentially between the outdoor fresh air inlet and the air outlet along the airflow direction; an expansion valve is also provided in the indoor side air duct. This air conditioning unit has the characteristics of high energy efficiency ratio, low energy consumption, and low water consumption."

[0004] While existing air conditioning units have achieved high energy efficiency, low energy consumption, and low water consumption, they still have some shortcomings: the evaporator structure of existing air conditioning units is simple, with the heat dissipation fins generally being flat plates and the coils generally being straight pipes in the length direction. This results in a small heat dissipation gap for air entering the evaporator and a small contact area with the heat dissipation fins and coils, leading to poor heat exchange effect. Secondly, the fins do not participate in the circulation of refrigerant, and the fin material is generally copper, which limits the amount of heat absorbed directly from the coils, resulting in a small refrigerant evaporation heat dissipation area. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, an evaporator tube for data center cooling is provided to solve the problems of small refrigerant flow area in the pipe and small contact area with air, which leads to poor heat exchange effect.

[0006] To achieve the above objectives, an evaporator tube for data center cooling is provided, comprising: an upper data center cooling tube and a lower data center cooling tube. A fin assembly and a main evaporator tube are connected between the upper and lower data center cooling tubes. The fin assembly is arranged in layers at equal intervals on the outside of the main evaporator tube. The main evaporator tube includes a vertical tube and an inclined tube. The fin assembly includes a first horizontal plate and a second horizontal plate. An inclined plate is connected between the first horizontal plate and the second horizontal plate. A first vertical connecting pipe is connected between the upper and lower parts of the first horizontal plate, and a second vertical connecting pipe is connected between the upper and lower parts of the second horizontal plate.

[0007] Furthermore, the upper end of the upper cooling pipe of the data center is connected to a liquid inlet pipe, and the lower end of the lower cooling pipe of the data center is connected to an air outlet pipe.

[0008] Furthermore, the lower side wall of the upper cooling pipe of the data center is provided with an upper flow hole, and the upper side wall of the lower cooling pipe of the data center is provided with a lower flow hole.

[0009] Furthermore, the main evaporator is provided in multiple sets between the upper and lower cooling pipes of the data center, and each main evaporator is formed by alternating vertical and inclined pipes from top to bottom, with both the upper and lower ends of each main evaporator being vertical pipes.

[0010] Furthermore, the upper vertical pipe of the main evaporator is connected to the upper flow hole, and the lower vertical pipe of the main evaporator is connected to the lower flow hole, and the main evaporator vertically penetrates the fin assembly.

[0011] Furthermore, the rib assembly has a cavity inside, and the rib assembly includes an inner copper material layer, and the outer side of the copper material layer is coated with a silver coating, while fish scale-shaped fins are provided on the outer surface of the silver coating.

[0012] Furthermore, a first connecting pipe is connected to the upper side of the first horizontal plate, and the first connecting pipe is connected to the lower side of the upper end of the data center cooling pipe away from the liquid inlet pipe. At the same time, a second connecting pipe is connected to the lower side of the second horizontal plate, and the second connecting pipe is connected to the lower end of the data center cooling pipe away from the air outlet pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By utilizing the vertical and inclined tubes included in the main evaporator tube, the length of the main evaporator tube in the vertical direction is extended, thereby increasing the refrigerant flow area inside. At the same time, by utilizing the first horizontal plate, continuous inclined plate and second horizontal plate included in the fin assembly, as well as the hollow internal arrangement of the fin assembly, the flow area of ​​the refrigerant in the horizontal direction is increased. Through the above technical solution, the contact area between the refrigerant and the outside air is increased, thereby improving the heat exchange effect with the air.

[0015] 2. By utilizing the copper layer, silver coating, and fish-scale fins included in the fin assembly, the cold source is accelerated to the outside during the refrigerant flow through the fin assembly. The high thermal conductivity of the silver coating and the fish-scale fins accelerate the evaporation rate of the refrigerant, converting it into a gaseous state. At the same time, an endothermic reaction is generated to cool the surrounding air flowing through it, thereby improving the heat exchange efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 4As shown, this utility model provides an evaporator tube for data center cooling, including: a data center cooling upper end tube 1 and a data center cooling lower end tube 2. A fin assembly 3 and a main evaporator tube 4 are connected between the data center cooling upper end tube 1 and the data center cooling lower end tube 2. The fin assembly 3 is arranged in layers at equal intervals on the outside of the main evaporator tube 4. The main evaporator tube 4 includes a vertical tube 41 and an inclined tube 42. The fin assembly 3 includes a first horizontal plate 31 and a second horizontal plate 34. An inclined plate 33 is connected between the first horizontal plate 31 and the second horizontal plate 34. A first vertical connecting pipe 32 is connected between the upper and lower parts of the first horizontal plate 31. At the same time, a second vertical connecting pipe 35 is connected between the upper and lower parts of the second horizontal plate 34. A liquid inlet pipe 5 is connected to the upper end of the data center cooling upper end tube 1, and an air outlet pipe 6 is connected to the lower end of the data center cooling lower end tube 2. An upper flow hole 11 is opened on the lower side wall of the data center cooling upper end tube 1, and a lower flow hole 22 is opened on the upper side wall of the data center cooling lower end tube 2.

[0023] In this embodiment, the upper cooling pipe 1 and the lower cooling pipe 2 of the data center, as well as the fin assembly 3 and the main evaporator pipe 4, constitute the main structure of the evaporator pipe for data center cooling involved in this application, and are used as evaporator pipe components in the data center cooling system.

[0024] Specifically, a fixing plate is welded to the end of the upper cooling pipe 1 and the lower cooling pipe 2 of the data center away from the liquid inlet pipe 5 and the gas outlet pipe 6 to facilitate the fixing of the evaporator.

[0025] Specifically, the upper and lower multi-layered fin assembly 3 forms an S-shaped structure with the first vertical connecting pipe 32 and the second vertical connecting pipe 35 connected end to end, so that the refrigerant can flow from the upper end pipe 1 of the data center cooling to the lower end pipe 2 of the data center cooling through the fin assembly 3, and then enter the circulation system of the cooling equipment.

[0026] like Figure 1 and Figure 2 In the middle, the main evaporator pipe 4 is provided in multiple sets between the upper end pipe 1 and the lower end pipe 2 of the data center cooling. Each main evaporator pipe 4 is formed by alternating vertical pipe 41 and inclined pipe 42 from top to bottom. At the same time, the upper and lower ends of each main evaporator pipe 4 are vertical pipes 41. The upper end vertical pipe 41 of the main evaporator pipe 4 is connected to the upper flow hole 11, and the lower end vertical pipe 41 of the main evaporator pipe 4 is connected to the lower flow hole 22. The main evaporator pipe 4 vertically penetrates the fin assembly 3.

[0027] Specifically, the upper and lower ends of multiple main evaporator tubes 4 are connected to the inner cavities of the upper and lower side tubes, so that the refrigerant can flow downward from the multiple main evaporator tubes 4 and carry out an evaporation and heat absorption reaction during the flow.

[0028] Specifically, while the main evaporator pipe 4 passes through the fin assembly 3, a sealing ring is provided in the through hole opened on the inclined plate 33 included in the fin assembly 3, so that the refrigerant inside the fin assembly 3 will not leak when the main evaporator pipe 4 passes through.

[0029] like Figure 1 , Figure 3 and Figure 4 In the middle, the rib assembly 3 has a cavity inside, and the rib assembly 3 includes a copper material layer 36 in the inner layer, and a silver coating 37 is coated on the outer side of the copper material layer 36. At the same time, fish scale fins 38 are provided on the outer surface of the silver coating 37. A first connecting pipe 12 is connected to the upper side of the first horizontal plate 31, and the first connecting pipe 12 is connected to the lower side of the end of the upper pipe 1 of the data center cooling away from the liquid inlet pipe 5. At the same time, a second connecting pipe 21 is connected to the lower side of the second horizontal plate 34, and the second connecting pipe 21 is connected to the end of the lower pipe 2 of the data center cooling away from the air outlet pipe 6.

[0030] Specifically, the fish-scale fins 38 are designed as arc-shaped copper sheets and are inclinedly bonded to the surface of the silver coating 37, which increases the contact area between the silver coating 37 and the air and improves the heat dissipation effect.

[0031] In use, the vertical and inclined tubes of the main evaporator tube extend its length vertically, increasing the refrigerant's internal flow area. Simultaneously, the first horizontal plate, continuous inclined plate, and second horizontal plate of the fin assembly, along with the hollow interior of the fin assembly, increase the refrigerant's horizontal flow area. These technical solutions increase the contact area between the refrigerant and the surrounding air, thereby improving heat exchange efficiency. Furthermore, the copper layer, silver coating, and fish-scale fins of the fin assembly accelerate the outward conduction of cold energy as the refrigerant flows through it. The high thermal conductivity of the silver coating and the fish-scale fins accelerate the refrigerant's evaporation, converting it into a gaseous state and simultaneously generating an endothermic reaction that cools the surrounding air, further improving heat exchange efficiency.

[0032] This invention provides an evaporator tube for data center cooling that effectively solves the problems of small refrigerant flow area and small contact area with air in existing evaporator tubes for data center cooling, leading to poor heat exchange performance. It improves the heat exchange performance of the evaporator by modifying the structure of the existing evaporator tube and changing the fin structure, thereby increasing the refrigerant flow area and path length in the evaporator.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
