Description

Technical Field

[0001] The utility model relates to an air heat exchanger device, in particular to a cellular unit plate type heat exchange core body used for cooling a data center. Background Art

[0002] With the rapid development of the Internet industry, the communications industry, and artificial intelligence, the process of national industrial digital transformation is accelerating, the data generated is growing exponentially, and the demand for computing power for servers and data centers is also rising. At the same time, in order to cope with the high energy consumption and heat dissipation problems caused by high-performance computing tasks and huge data processing, higher requirements are placed on the cooling technology of data centers.

[0003] For data centers located in high-latitude areas with low temperatures all year round and with requirements for air temperature and humidity, the use of air coolers is the most direct cooling method. The hot air exhausted from the data center room is sent to the air cooler, cooled to the design temperature and then sent back to the room. The cooling medium is the external ambient air. The air cooler does not require cooling towers or mechanical refrigeration to provide a cold source, and only consumes power from the fan, making it an extremely energy-saving cooling method.

[0004] In order to improve the heat exchange efficiency of air coolers, it is necessary to develop new plate types with compact structure, small flow resistance and high heat exchange performance.

[0005] Therefore, there is a particular need for a cellular unit plate heat exchange core for data center cooling to solve the above-mentioned existing problems. Utility Model Content

[0006] The utility model aims to provide a cellular unit plate heat exchange core for cooling a data center, which aims to address the deficiencies of the prior art and has the characteristics of compact structure and high heat transfer efficiency.

[0007] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0008] A dinocyte unit plate heat exchange core for data center cooling is formed by stacking a plurality of dinocyte unit plates, wherein two adjacent dinocyte unit plates are placed opposite to each other, and a plurality of dinocyte unit plates are stacked and stacked in sequence to form a plate heat exchange core; truncated cone dinocytes and rod-shaped dinocytes are arranged on the dinocyte unit plates, the truncated cone dinocytes are arranged in a matrix, the protrusions of two adjacent truncated cone dinocytes are in opposite directions, and the protrusion heights are the same; four rod-shaped dinocyte groups are arranged at the center positions of the four truncated cone dinocytes, each rod-shaped dinocyte group is a rod-shaped dinocyte arranged in parallel, the rod-shaped dinocytes are micro-protrusion structures, and the protrusions of two adjacent rod-shaped dinocytes are in opposite directions; the left and right edges of the dinocyte unit plates are designed with folded edge structures toward the hot air side, and the upper and lower edges of the dinocyte unit plates are designed with folded edge structures toward the cold air side, the folded edge height is equal to the protrusion height of the truncated cone dinocytes, and the contact folded edges of two adjacent dinocyte unit plates are welded to form a channel seal.

[0009] In a preferred embodiment of the present invention, the height of the truncated cone cell protrusion is 2mm-5mm.

[0010] In a preferred embodiment of the present invention, the height of the rod-shaped cell protrusions is 0.3mm-1mm.

[0011] Compared with the prior art, the utility model discloses a dinocyte unit plate heat exchange core for data center cooling, which is composed of a plurality of stacked dinocyte unit plates. The dinocyte unit plates are provided with truncated cone dinocyte structures and rod-shaped dinocyte structures. The truncated cone dinocytes are used to support the air flow channel and play an air turbulence role. The rod-shaped dinocytes are micro-convex structures, which not only increase the heat exchange area and make the heat exchange core structure more compact, but also enhance the heat exchange effect. The fully welded sealing method is adopted to achieve zero air leakage. The utility model is used for gas-liquid heat exchange and liquid-liquid heat exchange to achieve the purpose of the utility model.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0019] Example

[0020] like Figures 1 to 4 As shown, the utility model is a dinocyte unit plate heat exchange core for cooling a data center. The dinocyte unit plate heat exchange core 1 is formed by stacking a plurality of dinocyte unit plates 2. Two adjacent dinocyte unit plates 2 are placed opposite to each other. A plurality of dinocyte unit plates 2 are stacked and stacked in sequence to form a plate heat exchange core. Cone-shaped dinocytes 3 and rod-shaped dinocytes 4 are arranged on the dinocyte unit plates 2. The cone-shaped dinocytes 3 are arranged in a matrix. The protrusions of two adjacent dinocytes are in opposite directions and have the same protrusion height. Four rod-shaped cell groups are arranged at the center of the cone cell 3, each rod-shaped cell group is a rod-shaped cell 4 arranged in parallel, the rod-shaped cell 4 is a micro-convex structure, and the protrusions of two adjacent rod-shaped cells are in opposite directions; the left and right edges of the cell unit plate 2 are designed with a folding structure 5 towards the hot air side, and the upper and lower edges of the cell unit plate are designed with a folding structure 6 towards the cold air side, the folding height is equal to the protrusion height of the cone cell, and the contact folding edges of two adjacent cell unit plates 2 are welded to form a channel seal.

[0021] Reference Figure 1 High-temperature air flows in from the hot air side inlet of the Dingcell unit plate heat exchange core 1. After heat exchange, the hot air temperature decreases and flows out from the hot air side outlet of the Dingcell unit plate heat exchange core 1. Low-temperature air flows in from the cold air side inlet of the Dingcell unit plate heat exchange core 1. After heat exchange, the cold air temperature increases and flows out from the cold air side outlet of the Dingcell unit plate heat exchange core 1. The hot air and the cold air adopt a cross-flow heat exchange flow mode.

[0022] Reference Figure 3 The hot air passage is sealed by welding the hot air side folding edges 5 of two adjacent plates in contact, and the cold air passage is sealed by welding the cold air side folding edges 6 of two adjacent plates in contact.

[0023] Table 1 is a comparison of the heat transfer performance of the 2-cell unit plate heat exchange core and the flat plate heat exchange core under the same working conditions. It can be seen from Table 1 that under the same inlet Reynolds number, the heat transfer Nusselt number of the 2-cell unit plate heat exchange core is much higher than that of the flat plate heat exchange core.
