The following describes the main control box and the server provided by the present invention in detail with reference to the embodiments.

Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of a main control box according to a first embodiment of the present application (a first upper cover plate is hidden); FIG. 2 is a side view of a first embodiment of a master control box of the present application; fig. 3 is a partial side view of a second embodiment of a master control box of the present application.

The present application provides a master control box 10. The main control box 10 comprises a main control box body 1, a wind power assembly 13, a cooling circulation system 14 and a flow equalizing assembly 15. The main control box main body 1 includes a first accommodating chamber 11, and the first accommodating chamber 11 is provided with an opening 106. The first accommodating cavity 11 accommodates the wind power assembly 13, the cooling circulation system 14 and the flow equalizing assembly 15. The first accommodating chamber is provided with a main board 161, and the main board 161 is provided with a first heat generating device 162. The first heat generating device 162 may be, but is not limited to, a CPU. The first accommodating chamber 11 is provided with first ventilation parts 191 opposite to both side walls close to the opening 106. The first ventilation part 191 serves to flow wind. The first ventilation part 191 is a plurality of first ventilation holes, and the number of the first ventilation holes can be determined according to actual conditions. The wind bracket 12 is spanned on two side walls of the first accommodating cavity 11 close to the opening 106. The wind bracket 12 is used for mounting a wind power assembly 13. The wind bracket 12 and the main plate 161 are spaced apart from each other. When wind flow enters the main control box body 1 from the opening 106, a part of the wind flow enters the wind power assembly 13, is disturbed by the wind power assembly 13 and then enters the first accommodating cavity 11; another part of the wind current blows into the upper or lower part of the main board 161 through the gap between the wind bracket 12 and the main board 161 to dissipate heat from the main board 161 and the first heat generating device 162 and the like on the main board 161.

The lateral direction X of the wind power assembly 13 is set on a side of the wind bracket 12 facing away from the opening 106, and the air outlet of the wind power assembly 13 faces away from the opening 106. The cooling circulation system 14 is located in the first accommodation chamber 11. Cooling cycle system 14 includes a cold row assembly 141 and a cooling assembly 142. The cold row assembly 141 is in circulating communication with the cooling assembly 142. The cooling assembly 142 is thermally connected to the first heat generating device 162 for absorbing heat in the first heat generating device 162. The cold row assembly 141 is disposed on a side of the wind bracket 12 near the opening 106. Two ends of the cold discharging assembly 141 are respectively communicated with the corresponding first ventilating parts 191. The wind flows enter the cold row assembly 141 from both ends of the cold row assembly 141 through the two first ventilation parts 191, respectively.

The heat absorbed by the cooling component 142 from the first heat generator 162 in the cooling circulation system 14 enters the cold discharging component 141, and then after the heat is subjected to turbulent heat exchange with the wind power component 13, the temperature of the cooling component 142 is reduced after the heat is released, so that the heat in the first heat generator 162 is continuously absorbed, and the heat is subjected to reciprocating circulation flow heat exchange; the heated air flow flows out of the main control box body 1 along the first accommodating cavity 11. Through the mutual cooperation of the cooling circulation system 14 and the wind power assembly 13, the first heating device 162 and the internal heat dissipation of the main control box body 1 are realized, and the heat dissipation efficiency is improved. In addition, by arranging the cold row assembly 141 at the upstream position of the main control box 10, the wind flow is not affected by the wind power assembly 13, the first heat generating device 162, and the like, and the heat dissipation efficiency is improved.

In an actual process, when the air flow passing through the two first ventilation parts 191 enters the cold air discharging assembly 141, due to the resistance of the air flow, the air flow entering the cold air discharging assembly 141 is large in a partial region and small in a partial region, so that the air flow entering the cold air discharging assembly 141 cannot be homogenized. Therefore, the current equalizing assembly 15 in the main control box 10 has various wind current impedances. The different wind flow impedances control the wind flow entering the cold air discharging assembly 141, and further the wind flow homogenization is realized. The flow equalizing assembly 15 is disposed near the cold row assembly 141. After the wind flows through the flow equalizing assembly 15 in the first ventilating part 191, the wind flows can uniformly enter the cold air discharging assembly 141, the flow of the wind flows is optimally distributed, and the heat exchange efficiency is further enhanced.

The wind flow resistance in the flow equalizing assembly 15 can be set according to actual conditions. For example, the wind flow impedance is set in the transverse direction X or the vertical direction Y to realize the wind flow homogenization. The wind bracket 12 is detachably mounted at the position of the opening 106, so that the installation and the disassembly are convenient. The wind power assembly 13 is a number of fans. The fan may be one, two or more, etc. A number of fans are arranged side by side on the side of the wind cradle 12 facing away from the opening 106. In this embodiment, the number of the fans is four.

With continued reference to fig. 1-3, in one embodiment, the cooling assembly 142 includes a cold plate 1421, an inlet tube 1422, and an outlet tube 1423. The cold row assembly 141 includes a cold row frame 1411 and a number of flow conduits 1412. A plurality of flow conduits 1412 are arranged in parallel in a transverse direction along the cold row assembly 141, and adjacent flow conduits 1412 are arranged in parallel. Wherein the cold plate 1421, the inlet tube 1422, the plurality of flow channels 1412, and the outlet tube 1423 form a closed loop passage. The cold plate 1421 is thermally connected to the first heat generating device 162, and the cold plate 1421 absorbs heat in the first heat generating device 162 and transfers the heat to the cold row assembly 141 through the inlet pipe 1422, and then performs heat disturbing and temperature reduction through the wind power assembly 13. The number of the cold plates 1421 is plural. When there are more than two cold plates 1421, adjacent cold plates 1421 may be connected by cold tubes 1424. The number of the cold plates 1421 and the cold pipes 1424 may be determined according to actual conditions.

Because the plurality of flow pipelines 1412 are arranged in parallel in the transverse direction X, the cold row assembly 141 is close to the two end regions of the two first ventilation parts 191, when the wind flow enters the two ends of the cold row assembly 141, the flow path of the wind flow is short, the transverse impedance is small, and the ventilation quantity is large; and the middle area far away from the first ventilation part 191 has long wind flow path, large transverse resistance and large ventilation quantity. That is, the wind flow tends to flow into the fins 1413 of the cold row assembly 141 from the two ends of the cold row assembly 141 intensively, and a certain short circuit phenomenon exists, so that the heat exchange efficiency of the cold row assembly 141 is low.

Therefore, the present embodiment varies the cross-directional wind flow resistance in the cross direction X by changing the current equalizing assembly 15. The resistance of the transverse wind flow gradually decreases from the two ends of the flow equalizing assembly 15 to the middle, so that more wind flows enter the middle area of the flow equalizing assembly 15, and the homogenization of the wind flow is realized. The above-described variation of the lateral wind flow impedance across the flow equalization assembly 15 can be achieved in a number of ways. As will be explained in detail below.

Referring to fig. 4, fig. 4 is a partial top view of a main control box according to a second embodiment of the present application. In conjunction with fig. 1 and 3, in one embodiment, the current share assembly 15 includes a current share grid 151. The flow equalizing grid 151 is covered on an end face of the cold row component 141 facing away from the wind power component 13. The flow equalizing grid 151 is provided with a plurality of flow equalizing holes 1511 in a penetrating manner. The flow equalizing holes 1511 are arranged in an array. The flow equalizing grid 151 may be a mesh plate, which is provided with a plurality of flow equalizing holes 1511, and is distributed in a transversely symmetrical gradient.

The area of the flow equalizing hole 1511 in the unit area of the flow equalizing bar 151 gradually increases from the two ends of the flow equalizing bar 151 to the middle direction, so that the resistance of the transverse wind flow at the two ends of the flow equalizing bar 151 to the middle direction gradually decreases, and more wind flows enter the middle area of the flow equalizing bar 151. The unit area is mainly used as a comparison basis of the size of the flow equalizing hole 1511 and can be any area measurement unit.

Specifically, the area of the flow equalizing hole 1511 in the unit area is related to the size of the flow equalizing hole 1511 and the density of the flow equalizing hole 1511, so the area of the flow equalizing hole 1511 is adjusted by changing the size of the flow equalizing hole 1511 and the density of the flow equalizing hole 1511. The density of the flow equalizing holes 1511 is the number of the flow equalizing holes 1511 in a unit area, and the greater the number of the flow equalizing holes 1511 is, the greater the density of the flow equalizing holes 1511 is; otherwise, the lower the density of the flow equalizing holes 1511. The size of the flow equalizing hole 1511 is the area of one flow equalizing hole 1511 in a unit area, and the larger the area of the flow equalizing hole 1511 is, the larger the flow equalizing hole 1511 is; the smaller the equalizing hole 1511. The above-mentioned change in the size of the flow equalizing hole 1511 and the density of the flow equalizing hole 1511 can be at least the following three cases:

first, the size of the flow equalizing holes 1511 increases gradually from the two ends of the flow equalizing bar 151 to the middle, and the density of the flow equalizing holes 1511 is equal, that is, the area of the flow equalizing holes 1511 per unit area increases gradually from the two ends of the flow equalizing bar 151 to the middle.

Secondly, the flow equalizing holes 1511 are equal in size from the two ends of the flow equalizing bar 151 to the middle, and the density of the flow equalizing holes 1511 is gradually increased, that is, the area of the flow equalizing holes 1511 per unit area is gradually increased from the two ends of the flow equalizing bar 151 to the middle. As shown in fig. 3 of the present embodiment, the end region flow equalizing holes 1511 near the first ventilation portion 191 have a sparser distribution density, and the flow resistance of the wind flow passing through the cold row assembly 141 is greater. The middle region flow equalizing holes 1511 far away from the first ventilation part 191 are distributed more densely, and the flow resistance of the air passing through the cold row assembly 141 is smaller. Therefore, the larger the resistance level of the cross wind from R1 to R3 from the middle to both sides of the current sharing grid 151 is, the larger the resistance is. Among the above-mentioned different transverse wind current impedance levels, the size of single hole 1511 that flow equalizes keeps unchangeable, only distributes the interval change, and then changes the hole 1511 density that flow equalizes. In addition, the span/length of each transverse wind flow impedance can also be distributed according to the actual situation in a gradient mode.

Third, the flow equalizing holes 1511 increase in size and density from both ends of the flow straightener 151 towards the middle.

The sizes and densities of the adjacent flow equalizing holes 1511 may be set at equal intervals or at unequal intervals, wherein the sizes and densities of the flow equalizing holes 1511 are not limited to the three cases, but may be other types of cases as long as the area of the flow equalizing holes 1511 in a unit area gradually increases from the two ends of the flow equalizing grid 151 to the middle direction, and are not limited herein.

Referring to fig. 5, fig. 5 is a partial top view of a third embodiment of a main control box according to the present application. Referring to FIG. 1, in another embodiment, the flow equalization assembly 15 includes a flow equalization chamber 155. Both ends of the flow equalizing cavity 155 are respectively communicated with the corresponding first ventilating parts 191. The flow-equalizing chamber 155 can concentrate the flow of wind into the cold row assembly 141. The flow equalizing cavity 155 is provided with a plurality of flow equalizing rails 156 from two ends to the middle. The current share column 156 includes a first current share column 1561 and a second current share column 1562, the first current share column 1561 and the second current share column 1562 are vertically arranged. First flow straightener 1561 one end sets up near cold row's subassembly 141, and second flow straightener 1562 one end sets up near first ventilation portion 191. The area between the first current equalizing column 1561 and the second current equalizing column 1562 is communicated with the area of the cold row component 141. The flow equalizing cavity 155 is divided into a plurality of flow equalizing subcavities 1551 by the plurality of flow equalizing columns 156. From this, through control entering a plurality of sub-chambers 1551 that flow equalize the amount of wind that realize that the wind current is evenly distributed in transverse direction X. The number of the flow equalizing bars 156 can be one, two, three or more, and the like, and the number can be determined according to actual situations.

Referring to fig. 6, fig. 6 is a partial side view of a third embodiment of a main control box according to the present application. In conjunction with fig. 1 and 5, as one embodiment, the plurality of flow subchambers 1551 are the same height in the vertical direction Y of the opening 106. The width of the plurality of flow equalization subcavities 1551 gradually decreases in the direction that the opening 106 extends toward the cold row assembly 141. Therefore, the air inlet quantity entering the flow equalizing subcavity 1551 is adjusted to further change the impedance of the transverse airflow, so that more airflow enters the middle area of the cold row component 141, and further the airflow homogenization is realized.

In this embodiment, two flow equalizing bars 156 are disposed at two ends of the flow equalizing cavity 155, and the flow equalizing cavity 155 is divided into three flow equalizing sub-cavities 1551 by the two flow equalizing bars 156. The width w of the plurality of flow equalization cavities 1551 gradually decreases from the opening 106 to the cold row assembly 141. As shown in fig. 7, w3 is greater than w2 and less than w1, so that different lateral wind flow impedances are adjusted to realize uniform distribution of wind flow in the lateral direction X.

Referring to fig. 7 and 8, fig. 7 is a partial top view of a fourth embodiment of a master control box of the present application, and fig. 8 is a partial side view of the fourth embodiment of the master control box of the present application. Referring to FIG. 1, in another embodiment, the flow equalization assembly 15 includes a secondary chamber 157. The auxiliary chamber 157 is located below the flow-equalizing chamber 155. I.e., the secondary chamber 157 is located below the flow equalizing subcavities 1551. The auxiliary cavity 157 extends lengthwise in the same direction as the flow equalization cavity 155. Wherein, the two ends of the auxiliary cavity 157 are respectively communicated with the corresponding first ventilation parts 191. The widths of the flow equalizing cavities 1551 of the plurality of flow equalizing cavities 155 from the opening 106 to the cold row assembly 141 are the same. The heights of the plurality of flow equalizing chambers 155 in the vertical direction of the opening 106 are the same. The auxiliary cavity 157 is connected to a plurality of sub-cavities 1551 that flow equalize, if assist the intercommunication between cavity 157 and the sub-cavity 1551 that flow equalize have the intercommunicating pore 1571 to in making the air current in the auxiliary cavity 157 get into the sub-cavity 1551 that flow equalize that corresponds, and then adjust the air current flow in a plurality of sub-cavities 1551 that flow equalize, thereby realize the amount of wind homogenization.

Specifically, the number or the size of the communication holes 1571 corresponding to each flow equalizing cavity 1551 is determined by the position of the flow equalizing cavity 1551. In the direction of the opening 106 of the cold row member 141, the number of the communication holes 1571 is relatively large, or the area of the communication holes 1571 is relatively large. By the mode, air flow distribution in each flow equalizing subcavity 1551 is adjusted, and efficient heat exchange of fluid inside and outside the cold discharging assembly 141 is achieved. As shown in fig. 8, in the case that the communication hole 1571 is provided on the auxiliary chamber 157, the width w of the plurality of flow equalizing chambers 1551 may be kept uniform, w1= w2= w3.

Referring to fig. 9, fig. 9 is a partial side view of a fifth embodiment of a main control box according to the present application. Referring to FIG. 1, in one embodiment, the cold row assembly 141 includes a plurality of fins 1413. Fins 1413 are disposed in the transverse direction X between adjacent flow tubes 1412. The fins 1413 are capable of absorbing heat in the flow tubes 1412, thereby increasing the convective heat transfer area of the cold row assembly 141. The fin 1413 density gradually decreases along the flow tubes 1412 from both ends toward the middle. The fins 1413 are densely distributed near the end region of the first ventilation part 191, and the resistance to the lateral wind flow passing through the fins 1413 is large. The fins 1413 are distributed sparsely in the middle region away from the first ventilation part 191, and the resistance of the cross wind flow of the wind flow passing through the fins 1413 is small. Namely, the resistance of the transverse wind flow from the two ends to the middle is formed to be reduced from R3 to R1. The span/length of each level can also be distributed according to the actual situation in a gradient manner, and is not limited herein. The transverse airflow impedance is changed through the distribution form of the fins 1413, so that the uniform distribution of the airflow in the transverse direction X can be realized, the airflow uniformly enters the wind power assembly 13 after entering the fins 1413, and the heat dissipation uniformity is improved.

As can be seen from the above, in order to realize efficient heat exchange between the cooling circulation system 14 and the wind power module 13, the flow equalizing grid 151 is disposed at the cold row module 141 to realize uniform wind flow, thereby improving efficient heat exchange efficiency. Or the density change of the fins 1413 is changed, so that the air flow homogenization is realized, and the high-efficiency heat exchange efficiency is improved. Or the air flow homogenization is realized by simultaneously arranging the flow equalizing grid 151 and changing the density of the fins 1413, so that the high-efficiency heat exchange efficiency is improved. As shown in fig. 9, after the wind flows through the flow equalizing holes 1511 and/or the fins 1413 of the flow equalizing grid 151 in the first ventilation portion 191 for cascade flow equalization, the wind volume can be equally distributed, so that the efficient heat exchange of the wind flows inside and outside the cold air discharging assembly 141 is realized.

Of course, in an actual process, in order to achieve efficient heat exchange between the cooling circulation system 14 and the wind power assembly 13, the flow equalizing grid 151, the flow equalizing chamber 155, the flow equalizing rail 156 and the fins 1413 cooperate with each other to achieve wind flow equalization. Or the flow equalizing grid 151, the flow equalizing cavity 155, the flow equalizing rail 156 and the communication hole 1571 are matched with each other to realize the wind flow equalization. Or the air flow is homogenized by the mutual matching of the flow equalizing cavity 155, the flow equalizing rail 156, the communication holes 1571 and the fins 1413.

Referring to fig. 10, fig. 10 is a partial side view of a sixth embodiment of the main control box of the present application. With reference to fig. 1 and 2, in one embodiment, the cooling assembly 142 includes a cold plate 1421, an inlet tube 1422, and an outlet tube 1423. The cold row assembly 141 includes a cold row frame 1411 and a number of flow conduits 1412. A plurality of flow conduits 1412 are arranged in series and in a serpentine configuration. The cold plate 1421, the inlet tube 1422, the plurality of flow channels 1412, and the outlet tube 1423 form a closed circulation path. The cold plate 1421 is thermally connected to the first heat generating device 162, and the cold plate 1421 absorbs heat in the first heat generating device 162 and transfers the heat to the cold row assembly 141 through the inlet pipe 1422, and then performs heat disturbing and temperature reduction through the wind power assembly 13. The number of the cold plates 1421 is plural. When there are more than two cold plates 1421, adjacent cold plates 1421 may be connected by cold tubes 1424. The number of the cold plates 1421 and the cold pipes 1424 may be determined according to actual conditions.

Because the plurality of flow pipes 1412 are arranged in series and distributed in a serpentine shape, a temperature distribution of 'hot-top and cold-bottom' is formed in the cold row assembly 141, so that the wind flow entering the cold row assembly 141 cannot be homogenized and enters the wind power assembly 13. Therefore, in the present embodiment, the vertical wind flow resistance is different in the vertical direction Y by changing the current equalizing assembly 15. The impedance of the vertical wind flow is reduced from the vertical height direction of the flow equalizing assembly 15, so that more wind flows enter the upper area of the flow equalizing assembly 15, and the homogenization of the wind flows is realized. The change in vertical wind flow impedance across the flow equalization assembly 15 described above can be accomplished in a number of ways. As will be explained in detail below.

In one embodiment, with continued reference to fig. 1, 2, and 10, the current share device 15 includes a current share gate 151. The flow equalizing grid 151 is arranged on an end face of the cold row component 141 facing away from the wind power component 13. The flow equalizing grid 151 is provided with a plurality of flow equalizing holes 1511 in a penetrating manner. The flow equalizing holes 1511 are arranged in an array. The area of the flow equalizing holes 1511 in unit area is gradually increased from the upper part to the lower part of the flow equalizing grid 151 in the vertical direction Y, and then the vertical wind flow resistance of the flow equalizing grid 151 from the upper part to the lower part in the vertical direction Y is gradually reduced. The unit area is mainly used as a comparison basis of the size of the flow equalizing hole 1511 and can be any area measurement unit.

first, the size of the flow equalizing holes 1511 increases gradually from the upper part to the lower part of the flow equalizing grid 151 in the vertical direction Y, and the density of the flow equalizing holes 1511 is equal, that is, the area of the flow equalizing holes 1511 in a unit area increases gradually from the upper part to the lower part of the flow equalizing grid 151 in the vertical direction Y.

Secondly, the sizes of the flow equalizing holes 1511 are equal from the upper part to the lower part of the flow equalizing grid 151 in the direction, and the density of the flow equalizing holes 1511 is gradually increased, that is, the area of the flow equalizing holes 1511 in a unit area is gradually increased from the upper part to the lower part of the flow equalizing grid 151 in the vertical direction Y.

Third, the flow equalizing holes 1511 increase in size and density from the upper portion to the lower portion of the flow equalizing bar 151. As shown in fig. 10, in the embodiment, from one end of the inlet pipe 1422 to one end of the outlet pipe 1423 in the vertical height direction, the single flow equalizing hole 1511 is smaller and smaller while the number of the flow equalizing holes 1511 is kept unchanged; meanwhile, the density of the flow equalizing holes 1511 is gradually increased. A vertical wind flow resistance level variation from R1 to R4 in the vertical height direction is formed. Meanwhile, in the lateral direction X, the lateral wind flow resistance of the flow straightener 151 from the middle to both sides becomes large.

Specifically, the liquid with higher temperature heated by the first heat generating device 162 flows in the inlet pipe 1422, and the inlet pipe 1422 is close to the upper flow passage of the cold row assembly 141. The higher temperature liquid dissipates heat in the serpentine flow path and flows through outlet 1423 to the lower temperature liquid after dissipation. Outlet duct 1423 is proximate the lower flow path of cold row assembly 141. Thus, a "hot-top-cold" temperature distribution is formed within cold row assembly 141. After the resistance to the vertical wind flow in the vertical height direction, more wind flow can be input into the flow channel with higher temperature at the upper part, so that the heat dissipation is intensively enhanced, and the heat exchange efficiency is further improved.

The sizes and densities of the adjacent flow equalizing holes 1511 may be set at equal intervals or at unequal intervals, wherein the sizes and densities of the flow equalizing holes 1511 are not limited to the three cases, but may be other types of cases as long as the area of the flow equalizing holes 1511 in a unit area gradually increases from the upper portion to the lower portion of the flow equalizing grid 151 in the vertical direction Y, and are not limited herein.

Referring to fig. 11, fig. 11 is a schematic structural diagram of a main control box according to a seventh embodiment of the present application (hiding a first upper cover plate). Referring to fig. 1 and 2, in one embodiment, the master control box 10 includes a first air bridge 18. Two ends of the first air bridge 18 are respectively communicated with the first ventilating part 191. By providing the first air bridge 18, the air flow in the first ventilation part 191 enters the cold row assembly 141. The wind flow provides a good condition for heat dissipation of the first heat generating device 162 in the main control box 10 and other heat generating devices on the main board 161. Such as wind flow, primarily dissipates heat from the first heat generating device 162. The first air bridge 18 may have any structure, and may introduce both air flows in the two first ventilation parts 191 into the cold row assembly 141.

In one embodiment, the first air bridge 18 is a semi-enclosed cavity structure. The cold row component 141 and the first ventilation portion 191 are bridged, so that a dedicated circulation channel of the cold row component 141 is realized. Specifically, the first air bridge 18 includes an air bridge frame 181 and a plurality of connecting portions. The connection portion (not shown) is used to connect two ends of the air bridge frame 181 with the corresponding first ventilation portion 191.

In this embodiment, the air bridge frame 181 is the flow equalizing cavity 155, which saves materials. For example, the first connection portion 182 communicates one end of the uniform flow chamber 155 with a first ventilation portion 191. The second connecting portion 183 communicates the other end of the flow equalizing chamber 155 with the other first ventilation portion 191. Both the first connection portion 182 and the second connection portion 183 may be made of a flexible material. Because the flexible material possesses certain flexibility, be convenient for assemble between wind bridge frame 181 and the first ventilation portion 191, and the assembly leakproofness is high.

When the first air bridge 18 is matched with the flow equalizing grid 151 in the flow equalizing assembly 15, more air flow can enter the cold air exhaust assembly 141 through the flow equalizing assembly 15. Wherein the flow straightener 151 may be disposed on an end of the first air bridge 18 proximate to the cold row assembly 141. When the first air bridge 18 is matched with the flow equalizing cavity 155 in the flow equalizing assembly 15, the first air bridge 18 can also be the flow equalizing cavity 155, so that the cost is saved.

Referring to fig. 12, fig. 12 is an exploded view of a seventh embodiment of the main control box of the present application. Referring to fig. 1, in an embodiment, a side of the first air bridge 18 facing away from the main plate 161 is provided with an air bridge hole 184.

The air bridge hole 184 is communicated with the second ventilation portion 192 to introduce the air flow in the external environment into the first air bridge 18, so that the air volume entering the cold air discharging assembly 141 is further increased, and the heat dissipation efficiency is improved. The number of the air bridge holes 184 can be one, two or more, and the number can be determined according to actual conditions. Such as the air bridge openings 184 in this embodiment, are disposed along the length of the first air bridge 18. The second ventilation part 192 may be a plurality of second ventilation holes, and the number of the second ventilation holes may be determined according to actual situations.

In an embodiment, referring to fig. 1, 11 and 12, the main control box body 1 includes a first side plate 101, a second side plate 102, a first rear panel 103, a first upper cover plate 104 and a first lower cover plate 105. The first side plate 101, the second side plate 102, the first back plate 103, the first upper cover plate 104 and the first lower cover plate 105 enclose a first receiving cavity 11 having an opening 106. The first side plate 101 and the second side plate 102 are disposed opposite to each other. The first rear panel 103 and the opening 106 are disposed opposite to each other. The first upper cover plate 104 and the first lower cover plate 105 are disposed oppositely.

Wherein the first side plate 101 and the second side plate 102 are respectively provided with a first ventilation portion 191. The two first ventilation portions 191 are respectively communicated with two end positions of the cold row assembly 141 and used for providing air flow to the cold row assembly 141. The first rear panel 103 is provided with a third ventilation part 193. The third ventilation part 193 is communicated with the first accommodating chamber 11, so that the air inside the main control box 10 flows out through the third ventilation part 193. The first side plate 101 and the second side plate 102 are respectively provided with a fourth ventilation portion 194, the fourth ventilation portion 194 is communicated with the first accommodating cavity 11, the fourth ventilation portion 194 is located below the second ventilation portion 192, and the fourth ventilation portion 194 is used for heat dissipation of the main plate 161 and the second heat generating device 163 on the main plate 161.

In one embodiment, referring to fig. 1 and 2, the cold row assembly 141 is transversely disposed at an upper portion of a side of the wind turbine 12 adjacent to the opening 106. The height of the wind power assembly 13 in the vertical direction Y is the same as the height of the opening 106 in the vertical direction Y. The area of the orthographic projection of the cold row assembly 141 on the plane of the opening 106 accounts for half of the area of the wind power assembly 13 in the direction of the opening 106. I.e., the cold row assembly 141 occupies only the upper half of the height of the opening 106 of the main control box 10. In this way, the airflow entering the first ventilating portion 191 can flow through the cold air discharging assembly 141 to perform enhanced heat dissipation on the first heat generating device 162, such as a CPU. The airflow entering the fourth ventilation part 194 can directly enter the first accommodating cavity 11 in the main control box 10 to dissipate heat for the second heat generating device 163 on the main board 161, such as the PCIE expansion card 1631 and the memory bank 1632.

The cooling plate 1421 in the cooling assembly 142 is fixed above the first heat generating device 162, so that the cooling circulation system 14 does not affect the arrangement of the PCIE expansion card 1631 in the second heat generating device 163 of the first rear panel 103, so as to support more function expandability for users in a high density trend.

Referring to fig. 1, 2 and 9, the cooling module 142 further includes a liquid pump 1425, and the liquid pump 1425 may be connected in series with the cooling circulation system 14. Liquid pump 1425 may be connected directly in series with cold pipe 1424. The liquid pump 1425 may also be secured with the cold plate 1421 or the cold row assembly 141. In this embodiment, the liquid pumps 1425 are fixed to the cold row assembly 141 and distributed on one or two sides of the cold row assembly 141. The cooling module 142 includes at least one reservoir 1426. There are two liquid storage tanks 1426 as in the present embodiment. The liquid storage tank 1426 is distributed on two sides, a liquid pump 1425 is distributed outside the liquid storage tank 1426 on one side, and the liquid working medium enters the liquid storage tank 1426 through an inlet pipe 1422, and then flows out of the cold discharge assembly 141 through an outlet pipe 1423 after passing through the flow channel and the liquid pump 1425.

The cooling circulation system 14 may be a liquid loop cooling system driven by a liquid pump 1425. The cooling circulation system 14 may be a vapor-liquid phase change loop cooling system that is driven by gravity or capillary forces. The vapor-liquid phase change loop cooling system performs flowing and heat transfer by means of a phase change principle, a liquid working medium in the cold plate 1421 absorbs heat of the first heating device 162 and then is gasified, generated vapor flows to the cold discharge assembly 141 along with the inlet pipe 1422 and releases heat and condenses into liquid after meeting cold, and then condensate flows back to the cold plate 1421 through the outlet pipe 1423 and flows back to the cold plate 1421 through gravity or capillary force and the like to absorb heat repeatedly. Liquid flows in the cold pipe 1424 of the liquid loop system; and the vapor-liquid phase change loop cooling system is divided into a vapor pipe and a liquid pipe according to the flowing direction. The two cooling circulation systems 14 are somewhat different in principle but identical in construction. Therefore, through the cooling circulation, an external liquid supply system is not needed, and the limitation on the working scene of a machine room is reduced.

The heat dissipation process of the main control box 10 in the above embodiment is as follows: the heat of the first heat generating device 162 is first transferred to the cold plate 1421, and then transferred to the cold row assembly 141 along with the flow of the liquid by the liquid pump 1425. The cold discharging assembly 141 and the wind power assembly 13 perform strong turbulent heat exchange, the temperature of the liquid working medium is reduced, and the liquid working medium continuously flows to the cold plate 1421 to absorb the heat of the first heating device 162, so as to perform reciprocating circular flow heat exchange. The heated wind flows out along the third ventilation part 193 of the first rear panel 103 of the main control box 10.

Compared with the prior art, the transverse direction X of the wind power assembly 13 is arranged on one side surface of the wind power bracket 12 departing from the opening 106, and the air outlet of the wind power assembly 13 deviates from the opening 106. The cold row assembly 141 is disposed on a side of the wind bracket 12 close to the opening 106 in the transverse direction X. Two ends of the cold discharging assembly 141 are respectively communicated with the corresponding first ventilating parts 191.

Further, the current share assembly 15 has a plurality of different wind flow impedances. The air current in the first ventilation portion 191 enters the cold row assembly 141 through the flow equalizing assembly 15. The wind flow enters the cold discharge assembly 141 uniformly due to the flow equalizing assembly 15. Through cooling circulation system 14 and wind-force subassembly 13 mutually supporting, realize the vortex heat transfer, to the inside heat dissipation of first heating device 162 and main control box main part 1, promoted the radiating efficiency.
