Description

Technical Field

[0001] The utility model relates to the technical field of direct current power supply, in particular to a 540V direct current power supply device. Background Art

[0002] A DC power supply is an energy conversion device that converts other forms of energy into electrical energy to supply the circuit in order to maintain a steady flow of current. In the chemical fiber spinning industry, there are some key equipment such as spinning metering pumps in the spinning process. When the AC power grid experiences voltage transients, power outages and other faults, the equipment is not allowed to interrupt operation, otherwise it will cause great economic losses. Therefore, these companies need to configure backup power supplies in the power supply system.

[0003] During the operation of the power supply, the battery cells in the power supply need to be cooled. Otherwise, the increase in ambient temperature will affect the working state of the power supply, resulting in excessive power loss or battery expansion. Therefore, the battery needs to be cooled.

[0004] The existing patent (publication number: CN212210242U) discloses a high-voltage DC power supply device, which is provided with fins and evenly provided with circular holes. When the heat dissipation fan blows external air to the fins through the air inlet holes, it is easier to take away the heat on the fins and discharge the heat through the air outlet holes.

[0005] In view of the above problems, the existing patents provide solutions, but during the heat dissipation process, the gas that has absorbed heat will flow around the battery cell. When the hot air flow flows on the surface of the battery cell, the temperature difference between the battery cell and the hot air flow is small, so that the heat dissipation effect of this part is poor and the heat cannot be dissipated in time.

[0006] Therefore, a 540V DC power supply device is proposed. Summary of the invention

[0007] The purpose of the utility model is to provide a 540V DC power supply device, which can solve the problem that the temperature difference between the battery core and the hot air flow is small, so that the heat dissipation effect of this part is poor and the heat cannot be dissipated in time.

[0008] To achieve the above object, the utility model provides the following technical solutions: a 540V DC power supply device, comprising a shell and a battery core, the battery core is arranged inside the shell, a bracket is installed on the inner wall of the shell, the battery core is installed on the bracket, a circular ring is sleeved on the bracket, a gantry is installed on the circular ring, a pressure chamber is opened on the gantry, an exhaust groove is opened on the side wall of the pressure chamber, the exhaust groove is used to blow air to the surface of the battery core, and an air supply mechanism matched with the pressure chamber is provided on the shell;

[0009] The air supply mechanism includes a guide cavity opened on the bracket, an annular groove is opened on the inner wall of the circular ring sleeve, one end of the guide cavity is connected to the annular groove, a wind shield plate is evenly and obliquely installed in the annular groove, and a fan with an output end connected to the guide cavity is installed on the shell, and the pressure chamber is connected to the installation groove.

[0010] During the discharge process of the battery cell, the fan is started and the fan inhales low-temperature dust-free gas. At this time, the gas discharged from the fan is discharged into the installation groove through the guide cavity. The airflow discharged into the installation groove impacts the wind shield plate, thereby driving the annular sleeve to rotate. At this time, the annular sleeve drives the gantry to rotate around the battery cell. During this process, the gas in the installation groove enters the pressure chamber and finally flows out through the exhaust groove. Since the gantry is in a rotating state, the low-temperature gas discharged from the exhaust groove can evenly and directly contact the surface of the battery cell, thereby improving the heat dissipation effect of the battery cell.

[0011] Preferably, a heat dissipation port is provided on the shell, a fan blade is installed on the bracket, the fan blade cooperates with the heat dissipation port, and the rotating shaft of the fan blade is fixedly connected to the circular ring sleeve.

[0012] By setting up the heat dissipation port, the hot air flow in the shell can be discharged to the outside in time, reducing the heat exchange amount between the hot air flow and the low-temperature gas. The fan blades can also speed up the air flow rate in the shell, increasing the probability of the hot air flow drifting to the vicinity of the heat dissipation port, thereby facilitating the timely transfer of the hot air flow.

[0013] Preferably, a sponge is installed on the gantry, and the sponge is located on both sides of the exhaust groove.

[0014] After the low-temperature airflow hits the battery cell, its temperature rises and changes direction. At this time, the high-temperature airflow that has changed direction passes through the sponge. During this process, the sponge is deformed, thereby reducing the power of the high-temperature airflow, thereby ensuring that the high-temperature airflow can be transferred in time by the airflow generated by the fan blades.

[0015] Preferably, a filter is provided in the heat dissipation port, and the filter is used to prevent dust from entering the housing.

[0016] The heat dissipation effect of the battery cell can be improved by evenly opening holes on the outer wall of the shell, and the filter can prevent dust and other impurities in the air from entering the shell, thereby ensuring that the battery cell can dissipate heat normally.

[0017] Preferably, a grounding wire is provided on the housing.

[0018] The grounding wire can transfer the static electricity generated by the friction during the rotation of the ring sleeve in time, thus preventing the battery cell from being damaged by static electricity.

[0019] Preferably, a plurality of gantries are evenly and symmetrically mounted on the circular ring.

[0020] Since the circular ring sleeve is in a rotating state, multiple gantries are evenly arranged on the circular ring sleeve to ensure that the overall balance of the circular ring sleeve and the gantries is maintained, thereby ensuring that the circular ring sleeve can rotate normally, and multiple gantries can blow air to the surface of the battery cell in time, thereby improving the cooling effect.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The present application sets a circular ring, a gantry, a pressure chamber, and an exhaust groove; the gas exhausted from the fan is discharged into the installation groove through the guide cavity, and the airflow discharged into the installation groove impacts the wind shield plate, thereby driving the circular ring sleeve to rotate. At this time, the circular ring sleeve drives the gantry to rotate around the battery cell. During this process, the gas in the installation groove enters the pressure chamber and finally flows out through the exhaust groove. Since the gantry is in a rotating state, the low-temperature gas discharged from the exhaust groove can evenly and directly contact the surface of the battery cell. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figures 1 to 6 , the utility model provides a technical solution:

[0034] A 540V DC power supply device comprises a shell 1 and a battery cell 2, wherein the battery cell 2 is arranged inside the shell 1, a bracket 3 is installed on the inner wall of the shell 1, the battery cell 2 is installed on the bracket 3, a circular ring sleeve 4 is sleeved on the bracket 3, a gantry 5 is installed on the circular ring sleeve 4, a pressure chamber 6 is provided on the gantry 5, an exhaust groove 7 is provided on the side wall of the pressure chamber 6, the exhaust groove 7 is used to blow air to the surface of the battery cell 2, and an air supply mechanism matching the pressure chamber 6 is provided on the shell 1;

[0035] The air supply mechanism includes a guide cavity 8 opened on the bracket 3, an annular groove 9 is opened on the inner wall of the annular sleeve 4, one end of the guide cavity 8 is connected to the annular groove 9, a wind shield plate 10 is evenly and obliquely installed in the annular groove 9, and a fan 11 whose output end is connected to the guide cavity 8 is installed on the shell 1, and the pressure chamber 6 is connected to the installation groove.

[0036] During the discharge process of the battery cell 2, the fan 11 is started, and the fan 11 inhales low-temperature dust-free gas. At this time, the gas discharged from the fan 11 is discharged into the installation groove through the guide cavity 8. The airflow discharged into the installation groove impacts the wind shield 10, thereby driving the annular sleeve 4 to rotate. At this time, the annular sleeve 4 drives the gantry 5 to rotate around the battery cell 2. During this process, the gas in the installation groove enters the pressure chamber 6 and finally flows out through the exhaust groove 7. Since the gantry 5 is in a rotating state, the low-temperature gas discharged from the exhaust groove 7 can evenly and directly contact the surface of the battery cell 2, thereby improving the heat dissipation effect of the battery cell 2.

[0037] Specifically, Figure 4 As shown, a heat dissipation port 12 is provided on the housing 1 , a fan blade 13 is installed on the bracket 3 , the fan blade 13 cooperates with the heat dissipation port 12 , and the rotating shaft of the fan blade 13 is fixedly connected to the circular ring sleeve 4 .

[0038] By adopting the above technical solution, the heat dissipation port 12 is provided to discharge the hot air flow in the shell 1 to the outside in time, thereby reducing the heat exchange amount between the hot air flow and the low-temperature gas, and the fan blades 13 can accelerate the air flow rate in the shell 1, thereby increasing the probability of the hot air flow drifting to the vicinity of the heat dissipation port 12, thereby facilitating the timely transfer of the hot air flow.

[0039] Specifically, Figure 6 As shown, a sponge 14 is installed on the gantry 5 , and the sponge 14 is located on both sides of the exhaust groove 7 .

[0040] By adopting the above technical solution, the temperature of the low-temperature airflow rises and changes direction after impacting the battery cell 2. At this time, the high-temperature airflow that has changed direction passes through the sponge 14. During this process, the sponge 14 is deformed, thereby reducing the power of the high-temperature airflow, thereby ensuring that the high-temperature airflow can be transferred in time by the airflow generated by the fan blades 13.

[0041] Specifically, Figure 3 As shown, a filter screen 15 is disposed in the heat dissipation port 12 , and the filter screen 15 is used to prevent dust from entering the housing 1 .

[0042] By adopting the above technical solution, holes are evenly opened on the outer wall of the shell 1 to improve the heat dissipation effect of the battery cell 2, and the filter 15 can prevent impurities such as dust in the air from entering the shell 1, thereby ensuring that the battery cell 2 can dissipate heat normally.

[0043] Specifically, Figure 2 As shown, a grounding wire 16 is provided on the housing 1 .

[0044] By adopting the above technical solution, the static electricity generated by the friction during the rotation of the annular sleeve 4 can be transferred in time through the grounding wire 16, which plays a role in preventing the battery cell 2 from being damaged by static electricity.

[0045] Specifically, Figure 3 As shown, a plurality of gantries 5 are evenly and symmetrically mounted on the annular sleeve 4 .

[0046] By adopting the above technical scheme, since the annular sleeve 4 is in a rotating state, multiple gantries 5 are evenly arranged on the annular sleeve 4 to ensure that the annular sleeve 4 and the gantries 5 are kept balanced as a whole, thereby ensuring that the annular sleeve 4 can rotate normally, and multiple gantries 5 can blow air to the surface of the battery cell 2 in time, thereby improving the cooling effect.

[0047] Working principle: During the discharge process of the battery cell 2, the fan 11 is started, and the fan 11 inhales low-temperature dust-free gas. At this time, the gas discharged from the fan 11 is discharged into the installation groove through the guide cavity 8. The airflow discharged into the installation groove impacts the wind shield 10, thereby driving the annular sleeve 4 to rotate. At this time, the annular sleeve 4 drives the gantry 5 to rotate around the battery cell 2. During this process, the gas in the installation groove enters the pressure chamber 6 and finally flows out through the exhaust groove 7. Since the gantry 5 is in a rotating state, the low-temperature gas discharged from the exhaust groove 7 can evenly and directly contact the surface of the battery cell 2, thereby improving the heat dissipation effect of the battery cell 2.

[0048] By providing the heat dissipation port 12, the hot air flow in the shell 1 can be discharged to the outside in time, reducing the heat exchange amount between the hot air flow and the low-temperature gas, and the fan blades 13 can accelerate the air flow rate in the shell 1, increasing the probability of the hot air flow drifting to the vicinity of the heat dissipation port 12, and the heat dissipation effect of the battery cell 2 can be improved by evenly opening holes on the outer wall of the shell 1, and the filter 15 can prevent impurities such as dust in the air from entering the shell 1, thereby ensuring that the battery cell 2 can dissipate heat normally.

[0049] After the low-temperature airflow hits the battery cell 2, its temperature rises and changes direction. At this time, the high-temperature airflow that has changed direction passes through the sponge 14. During this process, the sponge 14 is deformed, thereby reducing the power of the high-temperature airflow, thereby ensuring that the high-temperature airflow can be transferred in time by the airflow generated by the fan blades 13.

[0050] Since the annular sleeve 4 is in a rotating state, multiple gantries 5 are evenly arranged on the annular sleeve 4 to ensure that the annular sleeve 4 and the gantries 5 are balanced as a whole, thereby ensuring that the annular sleeve 4 can rotate normally, and multiple gantries 5 can blow air to the surface of the battery cell 2 in time, thereby improving the cooling effect.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
