An accommodating space AS is formed between the second plate body 23 and the first plate body 22 , and the heat dissipation coil assembly 20 and the plurality of heat dissipation fins 21 are disposed in the accommodating space AS. By covering the heat dissipation coil assembly 20 and the plurality of heat dissipation fins 21 with the first plate body 22 and the second plate body 23 , the heat dissipation elements can be effectively protected to prolong the service life of the device.

It is worth mentioning that the heat dissipation door panel 2A of the present application is composed of a door panel for carrying heat dissipation components (eg, the heat dissipation fins 21 and the heat dissipation coil assembly 20 , etc.) and the heat dissipation components therein. Therefore, the door panels (for example, the first panel body 22 or the combination of the first panel body 22 and the second panel body 23 mentioned above) well-known to those skilled in the art can all be applied in the present application . In the following, the heat dissipation door panel 2A including the first plate body 22 and the second plate body 23 will be used as an example for description, but the present application is not limited to this.

A plurality of heat dissipation fins 21 are disposed on a side of the first plate body 22 adjacent to the cabinet body 2B, and each of the plurality of heat dissipation fins 21 has a heat dissipation surface 210 . More specifically, each heat sink 21 has two heat dissipation surfaces 210 corresponding to each other, and the distance between the two heat dissipation surfaces 210 is the thickness T of the heat sink 21 . Wherein, the thickness T of the heat sink 21 may be determined according to actual use requirements. When the thickness T of the heat sink 21 is large, the heat capacity of the heat sink 21 is increased and the heat dissipation effect can be improved. On the contrary, when the thickness T of the heat sink 21 is smaller, the volume occupied by the heat sink 21 decreases, so that more heat sinks 21 can be accommodated in the heat dissipation door panel 2A.

In some embodiments, the length of each heat sink 21 in the vertical direction is the height H of the heat sink 21 . Wherein, the height H of the heat sink 21 can be determined according to actual use requirements. When the height H of the heat sink 21 is large, the heat capacity of the heat sink 21 is increased, and the heat dissipation effect can be improved. It is worth mentioning that the height H of the heat sink 21 is preferably less than or equal to the length of the first plate body 22 in the vertical direction, so as to avoid being exposed by the first plate body 22 .

In some embodiments, the length of each heat sink 21 in a direction away from the first plate body 22 is the width W of the heat sink 21 . Wherein, the width W of the heat sink 21 can be determined according to actual use requirements. When the width W of the heat sink 21 is larger, the heat capacity of the heat sink 21 increases and the heat dissipation effect can be improved. It is worth mentioning that, when the heat dissipation door panel 2A has both the first plate body 22 and the second plate body 23, the width W of the heat sink 21 is less than or equal to the inner surface of the first plate body 22 (the surface away from the external environment) and the width W of the heat sink 21. The distance between the inner side surfaces of the second plate bodies 23 (surfaces away from the cabinet main body 2B).

In some embodiments, the plurality of cooling fins 21 are orthogonal to the inner surface of the first plate body 22 and are sequentially arranged on the first plate body 22 along the horizontal direction. Besides, the plurality of cooling fins 21 may also be orthogonal to the ground. It is worth mentioning that the term "orthogonal" used in this application means that two elements (for example, the plurality of heat sinks 21 and the first plate body 22) are substantially perpendicular to each other, which covers two elements. Unexpected situations such as small angles (eg, 0.1 degrees to 5 degrees) of components are generated due to tolerances or the assembly process.

It is worth mentioning that the plurality of heat sinks 21 may have two or more specific angles or two or more specific directions at the same time, and should not be limited to one specific angle or one specific direction.

In some embodiments, there may be a specific separation distance D between two adjacent heat sinks 21 . Wherein, the distance D between two adjacent heat sinks 21 in each group may be the same or different. In the present application, the term "separation distance D" refers to the distance between one side surface of the heat sink 21 and the side surface of the adjacent heat sink 21 on the same side. For example, the separation distance D between two adjacent fins 21 in each group may be the first length. By setting the distance D between two adjacent radiating fins 21 in each group to be the same, it is possible to prevent the cabinet body 2B from having a significant temperature gradient in the horizontal direction. However, the present application is not limited to the above-described manner.

In other embodiments, when more central processing units (CPUs) are stacked in the central area of the cabinet body 2B, the distance D between two adjacent heat sinks 21 in each group of the present application may be the first length or one of the second lengths. Wherein, the first length is smaller than the second length. Further, the distance D between the two adjacent heat sinks 21 located in the central area of the first plate body 22 is the first length, and the two adjacent heat sinks located in the peripheral area of the first plate body 22 The separation distance D between 21 is the second length. In this way, the heat dissipation effect of the central area of the first plate body 22 can be effectively enhanced by arranging the heat dissipation fins 21 with higher density in the central area.

In some embodiments, the plurality of heat sinks 21 can be fixed on the inner surface of the first plate body 22 by means of bonding, fitting, locking, etc., which are well known to those skilled in the art. For example, the inner surface of the first plate body 22 may be recessed with a plurality of engaging grooves, and the thickness T of the engaging grooves may be similar to the thickness T of the heat sink 21 (for example, it may be the same or slightly smaller than that of the heat sink 21 ). ). The heat sink 21 can be stably fixed on the first plate body 22 by means of clamping or interference fit. It is worth mentioning that the above-mentioned manners are only examples, and other setting manners may also be adopted in the present application, or two setting manners may be combined to obtain a more excellent fixing effect.

In the present application, the positions of the water outlet 201 and the water inlet 200 may be determined according to the position of the cooling device 101 . For example, the cooling device 101 can be disposed on the upper layer or the lower layer of the cabinet main body 2B, and is connected to the water outlet 201 and the water inlet 200 through the first circulation pipe 100 . In order to reduce the length/volume of the first circulation pipe 100 in the heat exchange system, the water outlet 201 and the water inlet 200 are preferably arranged on the side of the heat dissipation door panel 2A adjacent to the ceiling or the ground, so that the cooling device 101 can be as much as possible Close to the water outlet 201 and the water inlet 200 .

In some embodiments, when the cooling device 101 is disposed adjacent to the ground, the water outlet 201 and the water inlet 200 are located on a side of the first plate body 22 adjacent to the ground. More specifically, the openings of the water outlet 201 and the water inlet 200 may be orthogonal to the ground. By arranging the water outlet 201 and the water inlet 200 adjacent to the ground and orthogonal to the ground, the total length of the first circulation pipe 100 connected to the cooling coil assembly 20 can be effectively reduced. Based on the above configuration, the present application can further improve the space utilization of the entire device.

In some embodiments, when the cooling device 101 is disposed adjacent to the ceiling, the water outlet 201 and the water inlet 200 are located on the side of the first plate body 22 away from the ground. More specifically, the openings of the water outlet 201 and the water inlet 200 may be adjacent to the ceiling of the machine room, so as to effectively reduce the total length of the first circulation pipe 100 connected to the cooling coil assembly 20 .

Both ends of each of the plurality of heat dissipation coils 202 are in fluid communication with the water inlet 200 and the water outlet 201, respectively, and each of the plurality of heat dissipation coils 202 has a plurality of extension sections 2020 and at least one connecting section 2021, a plurality of The extending sections 2020 pass through the plurality of heat dissipation surfaces 210 in sequence, and at least one connecting section 2021 is connected to one end of two adjacent extending sections 2020 located on the same side. More specifically, the number of the plurality of extension segments 2020 may be N, and the number of the connecting segments 2021 may be N−1. For example, the number of the plurality of extension segments 2020 may be three, and the number of the connecting segments 2021 may be two. Alternatively, the number of the plurality of extension segments 2020 may be five, and the number of the connecting segments 2021 may be four.

In some embodiments, the heat dissipation surface 210 is orthogonal to the plurality of extensions 2020 . In other words, the plurality of extension sections 2020 and the heat dissipation surface 210 all form an angle of 90 degrees. However, the present application is not limited thereto. In other embodiments, the plurality of extension sections 2020 and the heat dissipation surface 210 can also have a specific angle other than 90 degrees.

In the case where the plurality of heat sinks 21 and the plurality of heat dissipation coils 202 are in contact with each other, the rate of heat conduction can be made faster. In some embodiments, each heat sink 21 may be provided with a plurality of through holes 211 in advance, and each through hole 211 corresponds to an extension 2020 in the heat dissipation coil 202 . Further, the periphery of the through hole 211 and the extension 2020 are in contact with each other, and the contact area between the heat sink 21 and the extension 2020 is proportional to the thickness T of the heat sink 21 (ie, the thickness of the periphery). Therefore, by increasing the thickness T of the heat sink 21 to increase the area of the periphery of the through hole 211 that is in contact with the extending section 2020, the heat conduction rate can be increased more effectively.

In some embodiments, a plurality of heat dissipation coils 202 are sequentially disposed on the first plate body 22 along a vertical direction. By arranging a plurality of heat dissipation coils 202 in sequence, the heat dissipation door panel 2A can be divided into a plurality of heat dissipation sections B. As shown in FIG. When more heat dissipation sections B are formed, the temperature of the entire heat dissipation door panel 2A will exhibit frequent periodic changes. For example, it presents: low temperature (the extension section 2020 of the first cooling coil 202 close to the water inlet 200 ), medium temperature (the extension section 2020 of the first cooling coil 202 near the water outlet 201 ), low temperature (the extension section 2020 of the first cooling coil 202 close to the water outlet 201 ) The extension section 2020 of the two heat dissipation coils 202 close to the water inlet 200), the medium temperature (the extension section 2020 of the second heat dissipation coil 202 close to the water outlet 201) . . .

In contrast, in the prior art, the entire heat dissipation door plate 2A has only one heat dissipation area B, which will generate a significant temperature gradient.

In this way, the hot gas in the cabinet 2 will be cooled when passing through the heat dissipation coil 202 and the heat dissipation fins 21 , so as to leave the heat dissipation door panel 2A in a low temperature state. Further, the gas outside the heat dissipation door panel 2A will be pushed to move in a direction away from the heat dissipation door panel 2A. In addition, after the air in the cabinet 2 leaves the heat dissipation door panel 2A and moves in a direction away from the heat dissipation door panel 2A, the air in the external environment can enter the cabinet body 2B from the side of the cabinet body 2B away from the heat dissipation door panel 2A. in order to form a good heat dissipation cycle.

The operations of the plurality of fans 24 are similar or the same as those described above, and will not be repeated here.

In some embodiments, when the heat dissipation door panel 2A of the cabinet 2 further includes a plurality of fans 24 , the first plate body 22 and the second plate body 23 respectively have a plurality of air holes. By providing the air holes, the hot air in the cabinet 2 is more easily driven by the fan 24 and leaves the cabinet 2 through the heat dissipation door panel 2A. In some embodiments, in order to improve the stability of the intake air, the plurality of air holes are spaced apart from each other by a fixed distance. In some embodiments, in order to improve the local heat dissipation effect, the plurality of air holes are spaced apart from each other at different distances. For example, the area that needs to improve the heat dissipation effect may have more air holes correspondingly.

In some embodiments, the heat dissipation door panel 2A of the cabinet 2 further includes a roller 25 , and the roller 25 is disposed on a side of the first panel body 22 adjacent to the ground. Since a large number of heat dissipation components such as heat dissipation coils 202 and heat dissipation fins 21 are provided in the heat dissipation door panel 2A of the present application, it is bound to have a certain weight. Therefore, by providing the rollers 25, the heat dissipation door panel 2A of the present application can be easily opened or closed. It is worth mentioning that, although only one roller 25 is shown in the drawings of the present application, the present application is not limited thereto. In other embodiments, the number of the rollers 25 can be two, three or more than three, which can be determined according to the actual usage.

To sum up, the heat exchange system conducts the heat in the cabinet through the first circulation pipe, and conducts the heat to the plurality of heat dissipation fins through the second circulation pipe, thereby effectively dissipating heat. Wherein, there is only heat transfer between the first circulation pipe and the second circulation pipe without fluid communication.
