It should be appreciated that in this embodiment, the air extraction module 30 should have a high protection level. The air-liquid heat exchanger 21 radiates heat through the main air intake 111, the first air intake 131, the second air intake 141, the air suction module 30 and the air outlet 101, and has high heat exchange efficiency. When a plurality of power cabinets are parallel-connected in the second direction, only the first air inlet 131 and the second air inlet 141 at the outermost side can be used for air intake. The air passing cavity 10A of the power cabinet located in the middle does not enter the air from the first air introduction port 131 and the second air introduction port 141 due to the limitation of the air pressure.
Referring still to fig. 5-6, the heating assembly is disposed in the protection cavity 10B and includes a high heating element 40 and a low heating element 50, the high heating element 40 is cooled by the liquid cooling plate 22, the high heating element 40 is an inversion module in this embodiment, so that the water pipe of the air-liquid heat exchanger 21 also passes through the support plate 15 to communicate with the liquid cooling plate 22, the low heating element 50 includes a direct current electric element 51, an alternating current electric element 53 and a capacitor module 52, the direct current electric element 51 is close to the first side wall 11, the alternating current electric element 53 is close to the second side wall 12 and is disposed at the bottom of the protection cavity 10B and is located below the air heat exchanger 60, and the capacitor module 52 is located between the direct current electric element 51 and the alternating current electric element 53 and is located below the high heating element 40. In the present embodiment, the lower surface of the capacitor module 52 is provided with a heat dissipating surface 521 parallel to the horizontal direction.
Wherein the dc electrical component 51 is disposed in the third zone, the ac electrical component 53 is disposed in the fourth zone, and the capacitor module 52 spans the third zone and the fourth zone. The high heat generating element 40 is located above the fourth zone. The electrical connection relationship in the protection cavity 10B is that the direct current electrical component 51 is connected with the capacitor module 52, the capacitor module 52 is connected with the high heat generating component 40, and the high heat generating component 40 is connected with the alternating current electrical component 53.
The air heat exchanger 60 is arranged on the inner surface of the second side wall 12, the air heat exchanger 60 is provided with a cold air port 61 for conveying cold air to the protection cavity 10B and a hot air port 62 for recovering hot air from the protection cavity 10B, the hot air port 62 and the cold air port 61 face the first side wall 11, the hot air port 62 is higher than the cold air port 61, in practical application, an air draft fan is further arranged at the hot air port 62, the axis of the air draft fan is parallel to a first direction, the air heat exchanger 60 is provided with a first air flow channel and a second air flow channel, the first air flow channel is communicated with a third air inlet 123 and an air passing port 151, the second air flow channel is provided with a cold air port 61 and a hot air port 62, the air draft module 30 further drives air to flow from the third air inlet 123 to the air outlet 101 through the air passing port 151, and the first air flow channel and the second air flow channel exchange heat with each other to take away heat of the second air flow channel. Wherein the high heat generating component 40 is adjacent to the hot air port 62.
In this embodiment, the electrical components in the protection cavity 10B mainly dissipate heat through liquid cooling and air cooling, wherein the high heat generating component 40 dissipates heat through liquid cooling, the liquid cooling dissipates heat efficiently, the low heat generating component 50 dissipates heat through air cooling, and the protection performance of the protection cavity 10B can be improved well due to the fact that the air heat exchanger 60 and the air-liquid heat exchanger 21 dissipate heat through external circulation, and the high heat generating component 40 is close to the hot air port 62 of the air heat exchanger 60, so that the cold air flowing out from the cold air port 61 of the air heat exchanger 60 can take away the heat of the low heat generating component 50 in the protection cavity 10B first, and then take away the heat of the high heat generating component 40, thereby ensuring the heat dissipation efficiency of the low heat generating component 50. The heat dissipation efficiency of the heating component in the protection cavity 10B can be maximally ensured by the liquid cooling and air cooling matched heat dissipation mode, and the protection performance of the protection cavity 10B is good.
In this embodiment, since the hot air port 62 of the air heat exchanger 60 is higher than the cold air port 61, the cold air of the air heat exchanger 60 can gradually take away the heat of the heating component in the protection cavity 10B in the process of flowing upwards in the protection cavity 10B, the air circulation is good, the high heating element 40 is lower than the hot air port 62, so that the resistance is small when the hot air flows back, and since the density of hot air in the air flow is lower than that of the air, the cold air is under when the hot air flows back and the hot air is over when the hot air flows back, so that the air heat exchanger 60 can dissipate the heat of the low heating element 50 and also dissipate the heat of the high heating element 40.
In this embodiment, the air heat exchanger 60 and the air-liquid heat exchanger 21 share the air extraction module 30, so as to share the air outlet 101, so that hot air generated by the protection cavity 10B is exhausted from the air outlet 101 at the top of the cabinet body 10, and when a plurality of power cabinets are used side by side along the first direction, the hot air of the air outlet 101 of the upstream power cabinet will not affect the main air outlet 111 of the downstream power cabinet, wherein the air heat exchanger 60 is attached to the inner surface of the second side wall 12, and is more attractive than the air heat exchanger 60 is attached to the outer surface of the second side wall 12, and if the air heat exchanger 60 is attached to the outer surface of the second side wall 12, the hot air of the first air flow channel easily flows into the main air outlet 111 of the downstream cabinet body 10.
The heating value of the capacitor module 52 in the low heating element 50 is the largest, the capacitor module 52 is located between the direct current electric element 51 and the alternating current electric element 53 and below the high heating element 40, wiring is facilitated, cold air of the air heat exchanger 60 flows through the alternating current electric element 53, the capacitor module 52 and the direct current electric element 51 and then flows through the high heating element 40 to be recovered to the hot air port 62, the temperature of the cold air is still lower after the cold air passes through the alternating current electric element 53 due to the small heating value of the alternating current electric element 53, so that heat of the capacitor module 52 can be well taken away, and the direct current electric element 51 can radiate outwards through the first side wall 11 due to the fact that the heat of the direct current electric element 51 is close to the first side wall 11, and therefore the heat dissipation efficiency of the low heating element 50 is high.
In this embodiment, the lower surface of the capacitor module 52 is provided with the heat dissipation surface 521 parallel to the horizontal direction, which is not only beneficial to the electrical coupling between the upper surface of the capacitor module 52 and the high heat generating component 40, but also makes the cold air better dissipate the heat of the capacitor module 52.
Referring to fig. 6, the first heat generating element 70 extends along a vertical direction, the first heat generating element 70 is disposed in the accommodating section of the first air duct 01 and forms an air passing gap with the air duct wall of the first air duct 01, the top end of the air passing gap is not higher than the input end of the accommodating section to allow the air flow of the first air inlet 112 to take away the heat of the first heat generating element 70 from top to bottom, wherein the first heat generating element 70 is located in the upper air outlet chamber 10D, mainly located in the vertical section of the cover 18, and the bottom end of the first heat generating element 70 is higher than the first air outlet 121. That is, the first heat generating member 70 is disposed in the first region. An "overwind gap" is understood to be used only for overwind and no other heat generating components can be placed in the overwind gap. In this embodiment, the first heating element 70 is a reactor, and the first heating element 70 is disposed in the first air duct 01 of the heat dissipation cavity 10C, on one hand, because the first heating element 70 is heavier and is disposed at the bottom of the cabinet 10, the load bearing performance is better, on the other hand, the hot air discharged from the first air outlet 121 by the first air duct 01 is further away from the third air inlet 123 as far as possible, and the hot air movement track of the first air outlet 121 is parabolic, thereby avoiding the turbulent flow of the hot air generated by the first heating element 70 to the cold air of the third air inlet 123. The first heat generating element 70 is located in the upper air outlet chamber 10D, so that the first heat generating element 70 is spaced from the ground by the lower air outlet chamber 10F, and the first heat generating element 70 is prevented from being affected by the heat radiation of the ground.
Since the air passing gap is formed between the cover 18 and the first abutting wall 13 and the second abutting wall 14, the flow speed of the cold air flowing through the second air inlet 113 is increased, the cold air flows collide with the air guiding surface 161 after flowing to the air guiding surface 161, the flow speed is further increased, the air flowing colliding with the air guiding surface 161 flows downwards along the outer part of the cover 18, heat radiated to the cover 18 by the first heat generating element 70 can be taken away, the heat dissipation efficiency of the first heat generating element 70 is further improved, and the air flowing not colliding with the air guiding surface 161 continues to flow to the second air outlet 122 due to the fact that the air guiding surface 161 is vertically spaced from the inner partition plate 17.
Because the heat insulation gap 03 exists between the top surface of the cover 18 and the cavity wall of the heat dissipation cavity 10C, the heat insulation gap 03 is matched with the air passing gap between the cover 18 and the air guide surface 161, so that the heat conduction efficiency between the cover 18 and the partition plate 16 is reduced, the heat of the first heat generating element 70 is prevented from being dissipated into the protection cavity 10B in a radiation manner, and the influence on electric components in the protection cavity 10B is further avoided. The heat radiation efficiency of the whole cabinet 10 is improved, so that the heat of the first heat generating member 70 is not easily transferred through the heat radiation phase.
The second heat generating element 80 is at least partially located in the second air duct 02. The second heat generating component 80 has a smaller heat than the first heat generating component 70, the second heat generating component 80 includes a fuse 81, a first connector 82 and a second connector 83, the fuse 81 is used for electrically coupling with the dc electrical component 51, the first connector 82 is a dc electrical connector, and the second connector 83 is an ac electrical connector connected with the ac electrical component 53. Since the heat generation amount of the fuse 81 is larger than the first connector 82 and the second connector 83, the temperature resistance of the fuse 81 is lower than the first connector 82 and the second connector 83, the fuse 81, the first connector 82 are located on one side of the first heat generating element 70 close to the first side wall 11 in the second direction, and the second connector 83 is located on the other side of the first heat generating element 70 close to the second side wall 12 in the second direction, facilitating the wiring operation of the first connector 82 and the direct current electric element 51 and the wiring operation of the second connector 83 and the alternating current electric element 53 and the fuse 81, the first connector 82 and the second connector 83. The fuse 81 is close to the second air inlet 113, and the first connector 82 is located below the fuse 81. The first connector 82 and the second connector 83 penetrate the inner partition 17 and extend into the lower outlet chamber 10F to improve heat dissipation efficiency. Correspondingly, a via hole for extending the dc electrical component 51 may be formed at the bottom end of the first side wall 11, and a via hole for extending the ac electrical component 53 may be formed at the bottom end of the second side wall 12.
In this embodiment, the first heat generating element 70 extends along the vertical direction, and is disposed in the accommodating section of the first air duct 01 and forms an air passing gap with the air duct wall of the first air duct 01, the top end of the air passing gap is not higher than the input end of the accommodating section to allow the air flow of the first air inlet 112 to take away the heat of the first heat generating element 70 from top to bottom, on the one hand, the first air inlet 112 is far away from the ground, thereby preventing the air flow entering the first air duct 01 when the ground temperature is high from being hot air, ensuring that the air flow entering the first air duct 01 is cold air far away from the ground, on the other hand, because the air passing section is only used for passing air, the air passing gap is formed between the first heat generating element 70 and the air duct wall of the first air duct 01, the heat of the first heat generating element 70 is concentrated, so that the cold air flow of the first air inlet 112 directly flows to the first heat generating element 70, and takes away the heat of the first heat generating element 70 from top to bottom, when the air flow flows into the air passing gap, on the air flow, on the other hand, the air flow can rapidly take away the heat of the first heat generating element 70, on the ground, on the other hand, the air outlet 121 is closer to the ground, the air outlet 121 is prevented from being far away from the ground, and the air inlet 121 is far away from the air inlet 70, and the air inlet is not directly flowing along the same with the air inlet, and the air inlet 70, on the side of the air path, and the air inlet side, and the air path is not directly has the air path, and the air path of the air path. It can be seen that, in the present technical solution, the cold air temperature of the first heating element 70 is low, the heat dissipation efficiency is high, and meanwhile, the hot air of the first heating element 70, i.e. the hot air of the first air outlet 121, is as close to the ground as possible, so as to avoid affecting the air inlet of the cabinet 10 above the heat dissipation cavity and on the same surface as the first air outlet 121 or affecting the downstream power cabinet.
Further, the second heating element 80 is at least partially located in the second air duct 02, because the second air inlet 113 and the second air outlet 122 are both located between the first air inlet 112 and the first air outlet 121, and the second air inlet 113 is higher than the second air outlet 122, therefore, when the heat productivity of the first air inlet 112 is greater than that of the second heating element 80, the second air outlet 122 is farther away from the ground than the first air outlet 121, the air inlet temperature of the first air inlet 112 is lower than that of the second air inlet 113, the air outlet temperature of the first air outlet 121 is higher than that of the second air outlet 122, so that the colder air flow can be the first heating element 70 to dissipate heat, the hotter air flow is closer to the ground, and the secondary air flow is far away from the ground, and when the heat productivity of the first heating element 70 is greater than that of the second heating element 80, the first heating element 70 and the second heating element 80 have higher heat dissipation efficiency, and simultaneously, because the heat efficiency of the first air outlet 121 is higher than that of the second air outlet 121, and the second air outlet 121 are also higher than that of the second air outlet 121, and the second air outlet 122 are not influenced by the heat dissipation element 10 and the heat dissipation element 10, and the heat dissipation element 122 are located at least along the same air duct 02, and the upper side of the second air outlet 121, and the upper side of the second air outlet 10 is not being located at the bottom of the second air outlet 121, and the upper part is avoided when the heat dissipation element is located at least, and the second air outlet 10 is located at the bottom of the air outlet and the air outlet 02, because the heat productivity of the second heat generating element 80 is low, the second air duct 02 can also take away the heat of the first air duct 01 in the heat dissipation process, so that the heat dissipation efficiency of the first heat generating element 70 is further improved. The first heating element 70 and the second heating element 80 are located in independent heat dissipation cavities, and hot air flowing through the first heating element 70 and the second heating element 80 is directly discharged, so that other electric elements are not interfered.
More preferably, on the basis that the temperature of the cold air of the first air inlet 112 is lower than that of the second air inlet 113, the air volume of the first air inlet 112 is larger than that of the second air inlet 113, so that on one hand, the first heating element 70 has higher heat radiation efficiency, and therefore the heat radiation efficiency of the second heating element 80 is lower, on the other hand, the air volume of the first air outlet 121 is also larger than that of the second air outlet 122, so that the hot air of the first air outlet 121 can also move along the parabolic track with the hot air of the second air outlet 122, and thus the hot air is far away from the air inlets of other air inlets above the heat radiation cavity 10C or the air inlets of the downstream power cabinet, and the second heating element 80 with less heat generation is arranged in the second air channel 02 with small air volume, thereby meeting the heat radiation requirement of the second heating element 80, and also being capable of assisting in heat radiation for the first heating element 70.
In this embodiment, the lower air outlet chamber 10F further forms the third air outlet 132 and the fourth air outlet 142 that are communicated with the air outlet 171 of the air outlet 151 on the first abutting wall 13 and the second abutting wall 14, so that the hot air flowing through the first heating element 70 can flow out through the third air outlet 132 and the fourth air outlet 142 in addition to the first air outlet 121, thereby reducing the amount of the hot air of the first air outlet 121, and being not easy to interfere the first air inlet 112 and the second air inlet 113 of the downstream power cabinet, and it should be understood that the first abutting wall 13 and the second abutting wall 14 are both suitable for being used in combination with other power cabinets, and when a plurality of power cabinets are combined in the second direction to form a power pack, only the third air outlet 132 and the fourth air outlet 142 located at the outermost side will air outlet, and the third air outlet 132 and the fourth air outlet 142 of the power cabinet located at the middle will not air outlet outwards due to the larger wind pressure of the adjacent power cabinet.
After the arrangement, the hot air of the whole power cabinet is discharged from the air outlet 101 at the top and the first air outlet 121 at the bottom, so that turbulence is not easy to be generated on the air inlet of the downstream power cabinet. In this embodiment, the high heat generating element 40 is disposed in the fourth region, the first heat generating element 70 is disposed in the first region, and the first heat generating element 70 is disposed substantially diagonally, so that two electrical elements with large heat generation are far away as far as possible, further improving the heat dissipation efficiency, and the dc electrical element 51 is disposed in the third region, the ac electrical element 53 is disposed in the fourth region, and the capacitor module 52 spans across the third region and the fourth region, which is also beneficial for wiring.
