[0002] With the rapid development of cloud computing, 5G communications, edge computing, the Internet of Things, artificial intelligence and other industries, the scale and usage of data centers are indeed growing, and the usage of IT equipment and server density are also increasing. About 40% of the energy consumption of data centers is used by refrigeration compressor units to cool the data centers.

The heat dissipation equipment currently designed for use with data centers is basically side-inlet or bottom-inlet, and the air is discharged from the top of the equipment. This results in the equipment being unable to be stacked. Flat layout will waste a lot of space. The heat exchange equipment used in data centers, as the power density of the cabinets increases, the amount of heat exchange required is also increasing. The specifications of the supporting heat dissipation equipment are getting larger and larger, and the number is also increasing, resulting in an increasing footprint, and the upper space cannot be fully utilized for stacking the equipment.

[0025] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0026] If the utility model involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.) when describing, it is necessary to define the directions involved, such as "In order to clearly express the positions and directions described in the utility model, the end close to the operator is the proximal end, and the end away from the operator is the distal end." Or define it with the paper as a reference, etc. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, it does not need to be defined here.

[0027] Define the vertical direction as Figure 1 The "vertical direction" marked in the figure is defined as the horizontal x direction. Figure 3 The "horizontal x direction" marked in the figure defines the airflow direction as Figure 3 The “air flow direction” is marked in the figure.

[0028] A stackable heat exchange device, such as Figures 1 to 3As shown, it includes a rectangular frame 1, and an air inlet 2 and an air outlet 3 are arranged in the horizontal direction of the frame 1. The air inlet 2 and the air outlet 3 are arranged oppositely, and a fan 4 is arranged at the air outlet 3. A fin heat exchange component is arranged on the path from the air inlet 2 to the air outlet 3. The fan 4 is used to make the air flow from the air inlet 2 to the air outlet 3. The direction from the air inlet 2 to the air outlet 3 is the airflow direction. The airflow direction is in the horizontal plane and perpendicular to the horizontal x direction. A fin heat exchange component is arranged in the frame 1, and the fin heat exchange component is located in the airflow direction. The gas enters the frame 1 from the air inlet 2, passes through the fin heat exchange component to the air outlet 3 and flows out of the fan 4. The air cavity is from the air inlet 2 to the air outlet 3.

[0029] The fin heat exchange assembly includes a first fin-tube heat exchange group and a second fin-tube heat exchange group. The first fin-tube heat exchange group includes at least one first fin-tube heat exchanger 5 arranged along the horizontal x direction. The second fin-tube heat exchange group includes at least one second fin-tube heat exchanger 6 arranged along the horizontal x direction. The first fin-tube heat exchanger 5 and the second fin-tube heat exchanger 6 are arranged at intervals. The extension direction of the first fin-tube heat exchanger 5 is inclined to the airflow direction, and the extension direction of the second fin-tube heat exchanger 6 is inclined to the airflow direction. The inclination direction of the first fin-tube heat exchanger 5 is opposite to the inclination direction of the second fin-tube heat exchanger 6, that is, an angle is formed between the first fin-tube heat exchanger 5 and the second fin-tube heat exchanger 6. This design helps to change the flow direction of air, so that the air generates more disturbances or vortices when flowing through the fins of the heat exchanger, and exchanges heat with the fins through convection and radiation, thereby increasing the contact area and contact time between the air and the fins, thereby improving the heat exchange efficiency and enhancing the heat exchange effect.

[0030] More specifically, the inclination direction of the first fin-tube heat exchanger 5 and the inclination direction of the second fin-tube heat exchanger 6 are symmetrical with respect to the airflow direction, that is, the first fin-tube heat exchanger 5 and the second fin-tube heat exchanger 6 are arranged in a V shape.

[0031] More specifically, the number of the first fin-tube heat exchangers 5 is greater than or equal to two and they are distributed in parallel with each other, and the number of the second fin-tube heat exchangers 6 is greater than or equal to two and they are distributed in parallel with each other, that is, the first fin-tube heat exchangers 5 and the second fin-tube heat exchangers 6 are arranged in a W shape, so that the heat exchange is more uniform while ensuring the heat exchange efficiency and effect.

[0032] As an embodiment of the present utility model, the angle between the first fin-tube heat exchanger 5 and the second fin-tube heat exchanger 6 is an acute angle, which reduces the overall footprint of the heat exchange device while ensuring the heat dissipation effect.

[0033] As an embodiment of the utility model, a heat dissipation groove 7 with only one side open is formed between the adjacent first fin-tube heat exchanger 5 and the second fin-tube heat exchanger 6, and the opening of the heat dissipation groove 7 faces or faces away from the airflow direction, so that the air can fully exchange heat when passing between the two fin heat sinks, thereby improving the heat dissipation effect.

[0034] More specifically, one end of the adjacent first fin-tube heat exchanger 5 and one end of the second fin-tube heat exchanger 6 are connected to a core sealing plate 8, the first fin-tube heat exchanger 5, the second fin-tube heat exchanger 6 and the core sealing edge form a heat dissipation groove 7 opening toward the air inlet 2, and the core sealing plate 8 is arranged close to the air outlet 3.

[0035] As an embodiment of the utility model, the first fin-tube heat exchanger 5 and the second fin-tube heat exchanger 6 have the same structure. The first fin-tube heat exchanger 5 includes a header and a plurality of fins arranged on the header. The fins are arranged at intervals along the air flow direction. A liquid inlet 9 and a liquid outlet 10 are arranged at one end of the header. The liquid inlet 9 is used for the refrigerant to enter the header, and the liquid outlet 10 is used for the refrigerant to flow out of the header. The liquid inlet 9 and the liquid outlet 10 of the first fin-tube heat exchanger 5 are connected to the second fin-tube heat exchanger 6. The liquid inlet 9 and the liquid outlet 10 of the tube heat exchanger 6 are arranged adjacent to each other, that is, the liquid inlet 9 and the liquid outlet 10 are arranged away from the core sealing plate 8, and the first fin tube heat exchanger 5, the second fin tube heat exchanger 6, the liquid inlet 9 and the liquid outlet 10 form a heat dissipation groove 7 facing the air outlet 3, so that the structure of the entire heat exchange device is more compact, the occupied space is smaller, and the distribution of the refrigerant in the heat exchanger is more uniform, which is beneficial to improving the heat exchange efficiency, can reduce the number and complexity of pipeline connections, and reduce the cost of installation and maintenance.

[0036] Specifically, the hot air enters the air cavity from the air inlet 2, passes through the fins of the first fin-tube heat exchanger 5 and the fins of the second fin-tube heat exchanger 6, and an obtuse angle is formed between the hot air and the fins. The hot air is dispersed and decelerated, and flows through the fin gap at a low speed to exchange heat and reduce the temperature, and then converges at the air outlet 3 and is discharged at a high speed by the fan 4.

[0037] As an embodiment of the utility model, a control cabinet 11 is arranged on one side of the frame 1, and a controller 12 is arranged in the control cabinet 11. The controller 12 is used to regulate the operation of the fan 4, the first fin-tube heat exchanger 5 and the second fin-tube heat exchanger 6. The control cabinet 11 is independently and closed, that is, the control cabinet 11 is not connected to the air cavity.

[0038] As an embodiment of the present invention, each of the first fin-tube heat exchangers 5 corresponds to a column of fans 4, and each of the second fin-tube heat exchangers 6 corresponds to a column of fans 4, and the number of fans 4 in each column is at least one. Preferably, each column includes two fans 4 to enhance the air suction and heat dissipation effect.

[0039] The frame 1 adopts a container frame, which is used to have sufficient strength support when stacking the heat exchange device. At the same time, it has the advantages of being easy to stack and transport. The stacked heat exchange device ensures the heat dissipation effect while fully utilizing the vertical space and saving the horizontal space.

[0040] As an embodiment of the present utility model, Figure 4 As shown, a plurality of the heat exchange devices are stacked in the vertical direction, and the plurality of heat exchange devices only need the floor space of one heat exchange device, thereby improving the utilization rate of the site. Figure 5 As shown, the two groups of heat exchange device groups are arranged back to back so that an air duct is formed between the two groups of heat exchange device groups. Hot air can enter the air inlet 2 of the heat exchange device on both sides from the air duct and then be discharged from the air outlet 3 for heat dissipation. The air inlet 2 and the air outlet 3 will not interfere with each other, thereby improving the heat dissipation efficiency.

[0041] The heat exchange device provided by the utility model improves a conventional heat dissipation device with bottom air inlet and top air outlet into a heat exchange device with side air inlet and side air outlet, and while ensuring the heat dissipation effect, the heat exchange device can be stacked and used. In the case of needing to increase the number of heat exchange devices, the occupied area is reduced. The heat exchange device is designed as a modular unit, and each module has an independent heat dissipation capacity and connection interface, which improves the plasticity of the heat dissipation mode and can be flexibly expanded or reduced according to the actual needs of the user.

[0042] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0043] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
