DETAILED DESCRIPTION

It should be understood that the orientation description "upper", "lower", "outer", "inner" is the orientation in the normal use state, and the "left", "right" direction represents the left and right directions shown in the specific corresponding schematic diagram, which can be the left and right directions in the normal use state or not.

Without more limitations, the element defined by the statement "including one" does not exclude the presence of additional identical elements in the process, method, article or device including the element. The term "connected" includes direct connection and indirect connection unless otherwise specified.

[0033] In the specific embodiments, the power module is applicable to any type of power supply, for example, the power module is applicable to an uninterruptible power supply; for example, the power module is also applicable to a dual-circuit power supply; for the convenience of description, the following is exemplarily described by taking that the power module is applicable to an uninterruptible power supply.

[0034] At present, the uninterruptible power supply has strict requirements on the size of the overall structure, for example, the width size and the height size, the power module 100 is provided with air inlets at the front end and air outlets at the rear end to dissipate heat of the power devices in the power module 100, generally, the power module 100 is provided with connecting terminals at the rear end, the connecting terminals need to be connected with the connectors of the overall cabinet, thereby reducing the area of the air outlet at the rear end of the power module 100 and limiting the heat dissipation of the power module 100, in view of the above problems, the power module 100 is provided to overcome the above problems.

[0035] In some embodiments, as shown in Figures 1 to 3 The power module 100 includes a housing 110 and a heat sink 120, the housing 110 surrounds to form a first accommodating cavity 111, the heat sink 120 is located in the first accommodating cavity 111, the heat sink 120 includes a plurality of heat dissipation fins 121, the heat dissipation fins 121 have opposite first ends 1211 and second ends 1212 in the extending direction, and the heat dissipation fins 121 have heat exchange cavities 122 therebetween.

[0036] Firstly, the power module 100 includes the housing 110 and the heat sink 120, the specific structure of the housing 110 is not limited, for example, the housing 110 is a cuboid structure, the size of which is designed according to actual requirements, the housing 110 surrounds to form the first accommodating cavity 111, the first accommodating cavity 111 is used for accommodating the heat sink 120 and the power device 160, the structure of the heat sink 120 itself includes the heat dissipation fins 121 and a base plate 123, one side of the base plate 123 is connected with the plurality of heat dissipation fins 121, the other side of the base plate 123 is connected or contacted with the power device 160, the connection includes direct connection and indirect connection, which can play a role of heat conduction for the power device 160, the power device 160 can be understood as an SCR (Silicon Controlled Rectifier, Silicon Controlled Rectifier), which is a kind of high-power electrical element, also known as thyristor, which can be used as a high-power driving device in an automatic control system to control high-power equipment with a small-power control. The specific connection mode can be determined according to actual conditions, for example, the power device 160 is bonded on the base plate 123, the heat generated by the power device 160 is transferred to the base plate 123, and then transferred to the heat dissipation fins 121 for heat dissipation.

[0037] The fins 121 in the heat sink 120 have opposite first ends 1211 and second ends 1212 in the extension direction. The extension direction of the fins 121 can be understood as the depth direction of the shell 110, that is, the depth direction of the power module 100 inserted into the uninterruptible power supply device 1. The gas generated by the fan blows in from the first ends 1211 of the fins 121 and blows out from the second ends 1212 of the fins 121. The distance between two adjacent fins 121 is the tooth gap, which is the heat exchange cavity 122. The gas blown in from the first ends 1211 of the fins 121 fully exchanges heat with the fins 121 in the heat exchange cavity 122, and the gas temperature rises to become hot gas blown out from the second ends 1212. The specific value of the tooth gap is not limited. It should be noted that when the heat sink 120 is manufactured by using aluminum extrusion or die casting and other processing technologies, the higher the ratio of tooth height to tooth gap, the more difficult the processing, the shorter the service life of the corresponding mold, and the higher the rejection rate of the processed heat sink 120. However, the heat dissipation area of the heat sink 120 per unit volume is limited, and the increase of the tooth gap will also lead to lower wind speed and lower heat exchange coefficient, so the values and the corresponding proportional relationship of the tooth height and the tooth gap need to be considered comprehensively.

[0038] In order to improve the heat dissipation efficiency of the heat sink 120 in the power module 100, the power module 100 is provided with a separate fan, for example, the power module 100 includes a first fan 130, which is used to dissipate heat from the heat sink 120. The shell 110 has a first through hole 112 between the first ends 1211 and the second ends 1212. The specific position of the first through hole 112 can be determined according to actual needs. For example, the first through hole 112 is close to the second end 1212. After the gas generated by the fan passes through most of the area of the fin 121, it is discharged through the first through hole 112. At this moment, the gas can fully exchange heat with the fin 121, which helps to dissipate heat from the heat sink 120. The size of the first through hole 112 can also be determined according to the size and number of the fins 121. For example, the first through hole 112 is a rectangular through hole. The length of the first through hole 112 is the same as or similar to the extension direction of the fin 121, and the width of the first through hole 112 is the distance between the two most distant fins 121 in the heat sink 120.

[0039] For the convenience of understanding, the heat sink 120 is exemplarily explained by directions, the fins 121 in the heat sink 120 have a first end 1211 and a second end 1212 in the horizontal direction, the air generated by the fan enters in the horizontal direction, is discharged in the horizontal direction, the first through hole 112 is arranged on the shell 110 between the first end 1211 and the second end 1212 in the horizontal direction, the first through hole 112 is a vertical direction through hole, the first through hole 112 connects the space in the vertical direction, the air generated by the fan enters in the horizontal direction, can be discharged in the horizontal direction through the second end 1212 and be discharged in the vertical direction through the first through hole 112, the design of the first through hole 112 increases the area of the exhaust port of the heat sink 120, and the heat dissipation efficiency is increased.

[0040] In some embodiments, as shown in Figure 2 and Figure 5 shown, considering that the power module 100 further includes a bypass connection terminal 150 and a power power device 160, the bypass connection terminal 150 is close to the second end 1212, the bypass connection terminal 150 is electrically connected with the cabinet connector 420, the heat sink 120 has a substrate 123 on the side of the fin 121 away from the first through hole 112, the power power device 160 is in contact with or connected with the substrate 123, for example, the power power device 160 is bonded on the substrate 123, the heat generated by the power power device 160 is transferred to the substrate 123, and is transferred to the fin 121 by the substrate 123 to dissipate heat. In order to further improve the heat dissipation efficiency, the cooling pipeline 170 is further arranged on the substrate 123, the cooling liquid is placed in the cooling pipeline 170, the cooling liquid can be a cooling liquid, or can be a refrigerant, the refrigerant is a substance that is easy to absorb heat to become a gas, and is easy to release heat to become a liquid, and the reversible phase change is used to transfer heat, thereby effectively assisting the heat dissipation of the substrate 123. Its specific form is not limited, for example, freon, hydrofluorocarbon, etc.

[0041] The application also provides a power supply system 10, as shown in Figure 4As shown, the power supply system 10 includes a power module 100 and a power distribution cabin module 200, the power distribution cabin module 200 includes power distribution devices and copper bars, considering the special structural requirements of the power distribution cabin module 200, for example, the front sealing plate of the power distribution cabin module 200 does not have the position of installing the fan due to the structural design problem, at the same time, considering that the operation of the fan inevitably exists the shaking condition, which may affect the air switch in the power distribution cabin module 200, therefore the power distribution cabin module 200 is also not suitable for installing the fan. Considering the heat dissipation of the power distribution cabin module 200, the power distribution cabin module 200 is located on the side of the power module 100 with the first through hole 112, the gas discharged through the first through hole 112 can be directly discharged into the power distribution cabin module 200, and the related devices in the power distribution cabin module 200 are subjected to convection heat dissipation, the related devices include fuses, air switches and Hall devices, etc., for example, the power distribution cabin module 200 is above the power module 100, then it is discharged upward into the power distribution cabin module 200 through the first through hole 112; for example, the power distribution cabin module 200 is below the power module 100, then it is discharged downward into the power distribution cabin module 200 through the first through hole 112. At the same time, in order to flow the gas, the power distribution cabin module 200 will also be correspondingly provided with an exhaust outlet. The related embodiments will be given in the following, which will not be described here.

[0042] At the same time, in order to accelerate the cooling of the power distribution cabin module 200, such as Figure 2 and Figure 4As shown, the first end 1211 and the fan have a cavity 113, the shell 110 has a second through hole 114, the second through hole 114 is located on the same side of the shell 110 as the first through hole 112, and the second through hole 114 communicates the cavity 113 and the power distribution compartment module 200. Specifically, the fan introduces external air into the inside of the power supply module 100. At this moment, the gas generated by the fan does not pass through any high-temperature components and can be called cold air. The cold air enters the first end 1211, exchanges heat with the heat sink 121, and becomes hot air from the second end 1212 and the first through hole 112. The hot air discharged from the first through hole 112 performs forced convection with the devices and copper bars of the power distribution compartment module 200, which helps to dissipate heat from the power distribution compartment module and improves the heat dissipation efficiency of the power distribution compartment module. In order to better utilize the power supply module 100 to dissipate heat from the devices and copper bars of the power distribution compartment module 200, for ease of description, the power supply module 100 is taken as an example including a first fan 130. The cavity 113 is provided between the heat sink 120 and the first fan 130 in the shell 110. The gas entering the cavity 113 through the first fan 130 is cold air. The second through hole 114 is provided on the shell 110 at the position of the cavity 113. The second through hole 114 is located on the same side of the shell 110 as the first through hole 112. The second through hole 114 communicates the cavity 113 and the power distribution compartment module 200. The specific shape and size of the second through hole 114 are not limited. For example, the second through hole 114 is a long strip-shaped through hole. For example, the second through hole 114 is a circular hole-shaped through hole. The cold air in the cavity 113 can directly enter the power distribution compartment module 200 through the second through hole 114 to cool the devices and copper bars. Compared with cooling the devices and copper bars by discharging hot air through the first through hole 112, the efficiency of cooling the devices and copper bars by discharging cold air through the second through hole 114 is better.

[0043] In some embodiments, as Figure 4As shown, the air guide plate 140 is arranged in the cavity 113, one end of the air guide plate 140 is in contact with the first end 1211, and the other end of the air guide plate 140 extends towards the fan and away from the second through hole 114. Specifically, considering that the housing 110 of the power module 100 needs to accommodate the heat sink 120 and the power power device 160 and other related devices, for example, after the gas generated by the first fan 130 blows out of the cavity 113, due to the blocking of related parts, it may cause the airflow to produce turbulence, and the gas in the cavity 113 cannot directly flow through the heat exchange cavity 122 between the heat dissipation fins 121 through the first end 1211. In order to improve the heat exchange efficiency and the smoothness of the airflow, the air guide plate 140 is arranged in the cavity 113, one end of the air guide plate 140 is in contact with the first end 1211, and the other end of the air guide plate 140 is close to the first fan 130 and away from the second through hole 114. It can be understood that after the first fan 130 generates gas, the flow channel of the gas gradually narrows from the first fan 130 to the first end 1211 of the heat sink 120. According to Bernoulli's principle, under ideal conditions, the sum of the kinetic energy, potential energy and pressure potential energy of unit volume of fluid at any cross section of the same flow pipe is a constant. Therefore, the narrowing of the cross section helps to improve the flow rate of the gas, thereby facilitating heat exchange. At the same time, the air guide plate 140 is arranged in an inclined manner, and the air guide plate 140 is also convenient for guiding the gas to flow into the power distribution cabin module 200 through the first through hole 112 after passing through the heat exchange cavity 122 between the heat dissipation fins 121.

[0044] The application also provides a power supply complete device 1, such as Figures 5 to 7As shown, in order to facilitate understanding, the working principle of the uninterruptible power supply device is simply explained. The UPS (Uninterruptible Power Supply) is an uninterruptible power supply containing an energy storage device, mainly used to provide uninterrupted power supply for some devices with high requirements for power supply stability. When the mains input is normal, the UPS supplies the mains voltage to the load, at this time the UPS is an AC power stabilizer, and it also charges the battery in the machine; when the mains is interrupted, the UPS immediately converts the DC power of the battery to continue supplying 220V AC power to the load through the inverter switching method, so that the load maintains normal work and protects the load software and hardware from damage. The UPS device can provide protection for both voltage overload and voltage undershoot. Uninterruptible power supplies can be widely used in: mining, aerospace, industry, communication, national defense, hospital, computer business terminal, network server, network equipment, data storage equipment, emergency lighting system, railway, shipping, transportation, power plant, substation, nuclear power plant, fire safety alarm system, wireless communication system, program-controlled switch, mobile communication, solar energy storage and conversion equipment, control equipment and its emergency protection system, personal computer and other fields. For double-circuit or double-switch electrical equipment, there are also similar scenes of alternating work of rectifier state and battery state in UPS.

[0045] The uninterruptible power supply has multiple working states, and the losses of different power devices in different working states are different. The alternating working mode is usually adopted, which is mainly divided into bypass working condition and normal working condition. The normal working condition has a heating device, for example, the heating device includes an inverter power tube and a rectifier power tube. For the normal working condition, it is divided into a mains state and a battery state. In the mains state, the battery state related power devices in the rectifier circuit, such as IGBT, diode, inductor, etc., are not running, and the mains state power devices in the rectifier circuit and the power devices in the inverter circuit continue to run. In the battery state, the battery state related power devices in the rectifier circuit and the power devices in the inverter circuit continue to run, and the mains state related power devices in the rectifier circuit are not running.

[0046] In the normal working condition, whether the mains state or the battery state related device needs to run through the power distribution cabin module 200; in the bypass working condition, it needs to run by using the power module 100, at this moment the circuit does not have the conversion dissipation of the rectifier and inverter, and the loss of the whole machine is relatively low. For the uninterruptible power supply device 1, the heat dissipation parts mainly include: the power module 100, the power distribution cabin module and the power module 300.

[0047] The whole machine device 1 comprises a power module 100, a power distribution cabin module 200, a power module 300 and a box body 400. The box body 400 of the whole machine device 1 can be understood as the shell of the whole machine device 1. The box body 400 forms a second containing cavity 410. The box body 400 in the second containing cavity 410 is provided with a cabinet connector 420. The power module 100, the power distribution cabin module 200 and the power module 300 are all installed in the second containing cavity 410. The power module 300 and the power distribution cabin module 200 are respectively located on the two sides of the power module 100. The specific arrangement form is not limited. The power module 100 can be understood as a bypass module in the uninterruptible power supply. The cabinet connector 420 is electrically connected with the bypass connection terminal 150 of the power module 100. The power distribution cabin module 200 is electrically connected with the power module 300.

[0048] It should be noted that for the uninterruptible power supply whole machine device 1, the parts that need to be cooled mainly include the power module 100, the power distribution cabin module 200 and the power module 300. The power module 100 and the power module 300 can share a fan or use a fan separately. For example, the power module 100 is provided with a first fan 130 and the power module 300 is provided with a second fan 310. The first fan 130 and the second fan 310 are controlled separately.

[0049] In order to facilitate understanding, first, the size of the heating power is described. The whole machine device 1 adopts an alternating working mode. It mainly includes bypass working condition and normal working condition. In the normal working condition, the operation mainly depends on the power module 300. The heating devices of the power module 300 include inverter power tubes and rectifier power tubes. The power module 300 is electrically connected with the power distribution cabin module 200. The power distribution cabin module 200 also needs to operate. The devices in the power distribution cabin module 200 and the copper bar generate a large amount of heat. Therefore, in the normal working condition, the main heat sources are the power module 300 and the power distribution cabin module 200. The power module 300 and the power distribution cabin module 200 need to be cooled. In the bypass working condition, the operation mainly depends on the power module 100. The heating devices of the power module 100 include power supply power devices 160. At the same time, the bypass connection terminal 150 is electrically connected with the cabinet connector 420. Part of the devices in the power distribution cabin module 200 also operate. However, compared with the normal working condition, the heat generated by the power distribution cabin module 200 is greatly reduced. Therefore, in the bypass working condition, the main heat sources are the power module 100 and the power distribution cabin module 200. The power module 300 and the power distribution cabin module 200 need to be cooled.

[0050] Therefore, after considering the heating problems of different modules in different working conditions, the whole machine device 1 can adopt different arrangement forms.

[0051] For example, Figure 6As shown, in the direction of gravity, the whole device 1 is arranged in sequence from top to bottom according to the order of the power distribution cabin module 200, the power supply module 100 and the power module 300, which can facilitate the replacement and maintenance of the line by the operator. The power distribution cabin module 200 is located above the power supply module 100, and the power supply power device 160 is hung upside down on the base plate 123 of the heat sink 120. The first through hole 112 and the second through hole 114 in the power supply module 100 are both arranged above the shell 110, so that the gas generated by the first fan 130 enters the power distribution cabin module 200 through the first through hole 112 and the second through hole 114 to forcibly cool the devices and copper bars.

[0052] Meanwhile, further considering that under normal working conditions, the power module 300 and the power distribution cabin module 200 will generate a large amount of heat. After the second fan 310 cools the power module 300, the hot gas may rise and flow back into the power distribution cabin module 200, causing the temperature of the power distribution cabin module 200 to further rise. At this moment, the first fan 130 of the power supply module 100 between the power module 300 and the power distribution cabin module 200 is turned on. The cold gas generated by the first fan 130 is discharged through the second end 1212 to block the hot gas rising from the power module 300, avoiding the hot gas of the power module 300 entering the power distribution cabin module 200. The cold gas sinking from the second end 1212 can also assist in cooling the power module 300. At the same time, the remaining gas generated by the first fan 130 enters the power distribution cabin module 200 through the first through hole 112 and the second through hole 114 to cool the devices and copper bars in the power distribution cabin module 200. Since the power supply module 100 is not working at this moment, the gas entering the power distribution cabin module 200 is cold, which has better cooling effect and accelerates the heat dissipation of the power distribution cabin module 200.

[0053] Under bypass working condition, the power distribution cabin module 200 generates a small amount of heat. At this moment, the speed of the first fan 130 can be increased to improve the efficiency of the power supply module 100. Part of the gas generated by the first fan 130 becomes hot gas after passing through the heat sink 121 and enters the power distribution cabin module 200 through the first through hole 112. Part of the cold gas generated by the first fan 130 directly enters the power distribution cabin module 200 through the second through hole 114. It should be noted that whether the gas is cold or hot, the flow of the gas forces natural heat dissipation to become convective heat dissipation, which is beneficial to improve the heat dissipation efficiency.

[0054] Exemplarily, in the direction of gravity, the whole device 1 can also be arranged in the order of the power module 300, the power supply module 100 and the power distribution cabin module 200 from top to bottom, and the power distribution cabin module 200 is located below the power supply module 100. Then the first through hole 112 and the second through hole 114 in the power supply module 100 are arranged at the lower part of the shell 110, so that the gas generated by the first fan 130 enters the power distribution cabin module 200 through the first through hole 112 and the second through hole 114 to forcibly cool the devices and the copper bars. Similarly, in the normal working condition, the second fan 310 of the power module 300 is turned on for cooling, the first fan 130 of the power supply module 100 is turned on to block the hot gas and also to cool the power distribution cabin module 200. In the bypass working condition, the second fan 310 of the power module 300 is turned off, the rotating speed of the first fan 130 can be increased to improve the efficiency of the power supply module 100. Part of the gas generated by the first fan 130 becomes hot gas after passing through the cooling fin 121 and enters the power distribution cabin module 200 through the first through hole 112, and part of the gas generated by the first fan 130 directly enters the power distribution cabin module 200 in the form of cold gas through the second through hole 114.

[0055] This structure uses the fan of the power supply module 100 to cool the power distribution cabin module 200, which can solve the problem that the power distribution cabin module 200 cannot independently install a fan due to structural problems, and also can optimize the whole device arrangement structure and reduce unnecessary fan installation. In order to accelerate cooling, the number of ventilation openings can be increased in the area where the power distribution cabin module 200 is installed in the box 400, so as to facilitate the flow and heat exchange of the gas.

[0056] In some embodiments, after the cooling pipeline 170 is filled with cooling liquid, when the power supply module 100 is in a low-temperature state, the cooling liquid in the cooling pipeline 170 may freeze. The expansion of the frozen volume inside the cooling pipeline 170 may cause the pipe to expand, resulting in the rupture of the cooling pipeline 170. The cooling liquid inside the cooling pipeline 170 will accumulate at the bottom when not working to cause the pipe to expand, and the bottom directly contacts the power supply power device 160, so that the pipe expansion will lift the power supply power device 160 to cause abnormal temperature rise and cause the machine to explode.

[0057] Exemplarily, as shown in Figure 8 The cooling pipeline 170 of the substrate 123 is provided with a raised end 171 extending downward, the raised end 171 has a space for storing cooling liquid, and the liquid in the cooling pipeline 170 can flow into the storage space of the raised end 171 under the action of gravity. The aggregation area of the cooling liquid can avoid the power supply power device 160, and even if the raised end 171 expands, it will not affect the power supply power device 160.

[0058] Exemplarily, as shown in Figure 9As shown, the heat sink 120 can be tilted, that is, there is an angle α1 between the plane where the substrate 123 is located and the vertical plane. The value of the tilt angle is not limited, as long as it meets the requirement that the liquid in the cooling pipe 170 flows to one end of the cooling pipe 170 under the action of gravity. For example, if the angle α1 between the plane where the substrate 123 is located and the vertical plane is 85 degrees, the coolant is located at one end of the cooling pipe 170, which can avoid the power device 160. Even if the tube expands, it will not affect the power device 160.

[0059] In some embodiments, such as Figure 10 As shown, the previous embodiment provides an embodiment in which the coolant will not accumulate in the connection area between the power device 160 and the substrate 123. The path of the cooling pipe 170 can also be adjusted. The arrangement of the cooling pipe 170 should avoid the area of ​​the heat source power device 160. The cooling pipe 170 is spaced at a preset distance from the connection fixing point, which is the connection position between the power device 160 and the substrate 123. This allows the cooling pipe 170 to bypass the area of ​​the power device 160 on the substrate 123, so that even if the pipe expands, it will not affect the power device 160.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
