Description

Technical Field

[0001] The present invention relates to the technical field of UPS power supply, and in particular to a UPS power supply overheat protection device and a control method thereof. Background Art

[0002] UPS power supply is an uninterruptible power supply with an energy storage device, which is mainly used to provide uninterruptible power supply to some equipment with high requirements on power supply stability.

[0003] Existing electronic devices, such as UPS power supplies, usually increase the air flow inside the electronic device by speeding up the fan speed or increasing the size of the air outlet when overheating occurs, thereby reducing the occurrence of overheating of internal electronic components; however, during the use of electronic devices, the air outlet position is easily adhered to some dust, lint and other impurities, resulting in the reduction or even blockage of the air outlet position; when the air outlet is blocked, even if the above two methods are used to deal with it, it is difficult to reduce the adverse effects of impurities on ventilation. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a UPS power supply overheat protection device and a control method thereof.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a UPS power supply overheat protection device, comprising a power supply housing, and further comprising:

[0006] A heat sink, the heat sink is slidably disposed inside the power supply housing, and a fan assembly is disposed inside the heat sink;

[0007] A pushing component, the pushing component is used to push the heat sink out from the inside of the power supply housing;

[0008] A mounting groove, the mounting groove is provided on the side wall of the heat dissipation box, a rotating column is provided inside the mounting groove, a through heat dissipation groove is provided on the rotating column, when the heat dissipation groove is in a vertical state, dust accumulation can be prevented, and when the heat dissipation groove is in a horizontal state, heat dissipation can be performed;

[0009] A shielding component, wherein the shielding component is disposed inside the heat sink, and when the heat sink is not fully extended, the shielding component is used to shield the position of the heat sink that does not extend out of the heat sink;

[0010] Existing electronic equipment, such as UPS power supplies, usually increase the airflow inside the electronic equipment by speeding up the fan speed or increasing the size of the air outlet when overheating occurs, thereby reducing the occurrence of overheating of internal electronic components; however, during the use of electronic equipment, the air outlet position is easily adhered to some dust, lint and other impurities, resulting in the shrinkage or even blockage of the air outlet position; when the air outlet is blocked, even if the above two methods are used to deal with it, it is difficult to reduce the adverse effects of impurities on ventilation;

[0011] Usually, the heat sink is located inside the power supply housing and dissipates heat through the heat dissipation holes on the front side thereof, and the heat dissipation slots on the rotating column on the heat sink are in a vertical state, that is, the upper and lower openings of the heat dissipation slots are blocked by the inner wall of the mounting slot, thereby preventing dust from accumulating inside the heat dissipation slots;

[0012] When the UPS power supply is overheated, the push component can be started to first start the rotation of the rotating column, so that the heat sink rotates to a horizontal state, that is, the upper and lower openings of the heat sink flip to a horizontal state, so as to be connected with the outside, and then the heat sink is pushed to extend out of the power supply housing. On the one hand, the number of heat sinks is increased, and the heat dissipation area is increased, and the heat dissipation effect is improved. On the other hand, since the newly added heat sink is in a vertical state before being extended, the upper and lower openings are blocked by the inner wall of the installation groove, thereby preventing the accumulation of external dust inside the heat sink, so that the newly added heat sink is in a smooth state when exhausting and dissipating heat, which is conducive to further improving the heat dissipation effect.

[0013] Furthermore, compared with the method of adjusting the size of the heat dissipation slot in the prior art, dust is accumulated inside the heat dissipation slot in the prior art. Even if the slot of the heat dissipation slot is enlarged, it will be blocked by the original dust, affecting the heat dissipation effect.

[0014] The present invention can set the notch area of ​​the heat dissipation slot to be larger during design, thereby ensuring a larger air outlet, and since dust will not accumulate inside before heat dissipation, the design has a better heat dissipation effect than the prior art when the notch area is the same as that of the prior art.

[0015] It should be further explained that there are some devices in the prior art for cleaning the original dust, but when the UPS power supply is working, the dust is cleaned, and the raised dust may cause short circuits and other damages to electronic components. The present invention does not need to clean the dust, thereby avoiding the problem of dust.

[0016] Preferably, it also includes:

[0017] A temperature sensor, the temperature sensor is arranged inside the power supply housing, and the temperature sensor is used to detect the temperature inside the power supply housing;

[0018] A controller, when the temperature inside the power supply housing is overheated, the controller controls the first electric cylinder to push the heat sink outward to extend the heat sink, and the controller is not shown in the figure;

[0019] Among them, a temperature sensor is set to detect the temperature inside the power supply. When the temperature reaches the set value, it is determined that the power supply is overheated and the heat dissipation needs to be increased. Therefore, the controller controls the pushing component to start pushing the heat dissipation box outward, adding new heat dissipation slots to improve the heat dissipation efficiency.

[0020] Preferably, the shielding component comprises:

[0021] A sliding member, wherein the sliding member is slidably connected to the inside of the heat dissipation slot, and a first spring is arranged between the sliding member and the heat dissipation slot;

[0022] A shielding belt, one end of which is fixed to the sliding member, and the other end of which is provided with a winding device, the shielding belt being wound and fixed on a winding shaft of the winding device;

[0023] A positioning groove, the positioning groove is provided on the surface of the power supply housing;

[0024] A limiting component cooperates with the positioning groove to limit the sliding member.

[0025] In a second aspect, the present invention provides a control method for a UPS power supply overheat protection device, the control method comprising the following steps:

[0026] Obtain overheating information detected by a temperature sensor;

[0027] According to the overheating information, the rotating column is first controlled to rotate, so that the heat sink is flipped from a vertical state to a horizontal state, so that the heat sink is exposed and connected to the outside, and then the pushing component is started to push the heat sink to move outward;

[0028] Obtaining obstruction information detected by the pressure sensor;

[0029] According to the obstruction information, the heat dissipation box is controlled to move backward and connect with the strip-shaped through hole;

[0030] When overheating is detected, the heat dissipation box is pushed outward to increase the heat dissipation area, thereby facilitating the reduction of the temperature inside the power supply housing.

[0031] When excessive pressure is detected, it means that an obstacle is encountered in the process of pushing the heat sink outward, so the heat sink is controlled to move backward and dissipate heat from the side.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. When the UPS power supply is overheated, the pushing component can be started to push the heat sink to the outside of the power supply housing, and the rotating column can be started to rotate, so that the heat sink is horizontal and connected to the outside. On the one hand, the number of heat sinks is increased, thereby increasing the heat dissipation area and improving the heat dissipation effect. On the other hand, since the newly added heat sink is in a vertical state before leaking out and is not connected to the installation slot, it can avoid the accumulation of external dust inside the heat sink, so that the newly added heat sink is in a smooth state during exhaust and heat dissipation, which is beneficial to further improve the heat dissipation effect.

[0034] 2. Compared with the method of adjusting the size of the heat sink in the prior art, dust accumulates inside the heat sink in the prior art. Even if the slot of the heat sink is enlarged, it will be blocked by the original dust, affecting the heat dissipation effect. The present invention can set the slot area of ​​the heat sink to be larger during design, thereby ensuring a larger air outlet. Moreover, since dust will not accumulate inside before heat dissipation, the above design has a better heat dissipation effect than the prior art when the slot area remains the same size as the prior art.

[0035] 3. There are also some devices for cleaning the original dust in the prior art, but when the UPS power supply is working, the dust is cleaned, and the raised dust may cause short circuits and other damages to electronic components. The present invention does not need to clean the dust, thereby avoiding the problem of dust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0051] like Figures 1 to 12 A UPS power supply overheat protection device shown includes a power supply housing 1 and also includes:

[0052] A heat sink 2 is slidably disposed inside the power supply housing 1, and a fan assembly is disposed inside the heat sink 2;

[0053] A pushing component, which is used to push the heat sink 2 out from the inside of the power supply housing 1;

[0054] The mounting groove 3 is provided on the side wall of the heat dissipation box 2. A rotating column 4 is provided inside the mounting groove 3. A through heat dissipation groove 5 is provided on the rotating column 4. When the heat dissipation groove 5 is in a vertical state, dust accumulation can be prevented. When the heat dissipation groove 5 is in a horizontal state, heat dissipation can be performed.

[0055] The shielding component is disposed inside the heat sink 5, and when the heat sink 2 is not fully extended, the shielding component is used to shield the heat sink 5 from the position of the heat sink 2 that does not extend out of the heat sink;

[0056] Existing electronic equipment, such as UPS power supplies, usually increase the airflow inside the electronic equipment by speeding up the fan speed or increasing the size of the air outlet when overheating occurs, thereby reducing the occurrence of overheating of internal electronic components; however, during the use of electronic equipment, the air outlet position is easily adhered to some dust, lint and other impurities, resulting in the shrinkage or even blockage of the air outlet position; when the air outlet is blocked, even if the above two methods are used to deal with it, it is difficult to reduce the adverse effects of impurities on ventilation;

[0057] It should be noted that a gear 6 is fixed on the rotating shaft of all rotating columns 4, a rack 7 is provided on one side of the gear 6, and the rack 7 is connected to the first electric cylinder 8, so that the rack 7 is driven to move by starting the first electric cylinder 8, and the gear 6 is driven to rotate by the rack 7, so that the rotating column 4 is driven to rotate by the gear 6, so that the heat dissipation slots 5 in all rotating columns 4 are synchronously changed between the vertical or horizontal state;

[0058] Normally, the heat dissipation box 2 is located inside the power supply housing 1, and dissipates heat through the heat dissipation holes on the front thereof, and the heat dissipation slots 5 on the rotating column 4 on the heat dissipation box 2 are in a vertical state, that is, the upper and lower openings of the heat dissipation slots 5 are blocked by the inner wall of the mounting slot 3, thereby preventing dust from accumulating inside the heat dissipation slots 5;

[0059] When the UPS power supply is overheated, the rotating column 4 is first started to rotate so that the heat dissipation slot 5 is rotated to a horizontal state, that is, the upper and lower openings of the heat dissipation slot 5 are flipped to a horizontal state, so as to be connected with the outside, and then the pushing component is started to push the heat dissipation box 2 to extend out of the power supply housing 1. On the one hand, the number of heat dissipation slots 5 is increased, thereby increasing the heat dissipation area and improving the heat dissipation effect. On the other hand, since the newly added heat dissipation slot 5 is in a vertical state before being extended, the upper and lower openings are blocked by the inner wall of the mounting slot 3, thereby preventing the accumulation of external dust inside the heat dissipation slot 5, so that the newly added heat dissipation slot 5 is in a smooth state during exhaust and heat dissipation, which is conducive to further improving the heat dissipation effect.

[0060] Furthermore, compared with the method of adjusting the size of the heat dissipation slot 5 in the prior art, dust is accumulated inside the heat dissipation slot 5 in the prior art. Even if the slot of the heat dissipation slot 5 is enlarged, it will be blocked by the original dust, affecting the heat dissipation effect.

[0061] The present invention can set the notch area of ​​the heat dissipation slot 5 to be larger during design, thereby ensuring a larger air outlet, and since dust will not accumulate inside before heat dissipation, the above design has a better heat dissipation effect than the prior art when the notch area is the same as that of the prior art.

[0062] It should be further explained that there are some devices in the prior art for cleaning the original dust, but when the UPS power supply is working, the dust is cleaned, and the raised dust may cause short circuits and other damages to electronic components. The present invention does not need to clean the dust, thereby avoiding the problem of dust.

[0063] As a further embodiment of the present invention, it also includes:

[0064] A temperature sensor 9 is disposed inside the power supply housing 1 and is used to detect the temperature inside the power supply housing 1;

[0065] A controller, when the temperature inside the power supply housing 1 is overheated, the controller controls the first electric cylinder 8 to push the heat sink 2 to move outward and extend the heat sink 2. The controller is not shown in the figure;

[0066] Among them, a temperature sensor 9 is set to detect the temperature inside the power supply. When the temperature reaches the set value, it is determined that the power supply is overheated and the heat dissipation needs to be increased. Therefore, the controller controls the pushing component to start pushing the heat dissipation box 2 outward, adding a new heat dissipation slot 5 to improve the heat dissipation efficiency.

[0067] As a further embodiment of the present invention, the shielding assembly comprises:

[0068] A sliding member, the sliding member is slidably connected to the inside of the heat dissipation slot 5, and a first spring 11 is provided between the sliding member and the heat dissipation slot 5;

[0069] A shielding belt 12, one end of which is fixed to the sliding member, and a winding device 16 is provided at the other end of the shielding belt 12, and the shielding belt 12 is wound and fixed on the winding shaft of the winding device;

[0070] A positioning groove 13, which is formed on the surface of the power supply housing 1;

[0071] A limiting component, which cooperates with the positioning groove 13 to limit the sliding member;

[0072] It should be noted that the limiting component can adopt a second electric cylinder 14, which is fixed on the sliding member. When the second electric cylinder 14 moves to the position of the positioning groove 13, the second electric cylinder 14 is started, and the movable end of the second electric cylinder 14 is inserted into the positioning groove 13, thereby limiting the sliding member.

[0073] The winding device 16 is a prior art device, including a spiral spring, a winding shaft and other components, and its working method is not described in detail here;

[0074] Among them, multiple temperature intervals can be set, for example, 40-60 degrees Celsius is set as the first temperature interval and 60-80 degrees Celsius is set as the second temperature interval. When the temperature detected by the temperature sensor 9 is in the first temperature interval, the heat dissipation pressure is relatively small, and the pushing component is controlled to push 5 cm, which is the first stroke push, so that the heat dissipation slot 5 extends halfway; when the temperature detected by the temperature sensor 9 is in the second temperature interval, the heat dissipation pressure is relatively large, and the pushing component is controlled to push another 5 cm, which is the second stroke push, so that the heat dissipation slot 5 is fully extended; thereby adapting to different heat dissipation requirements;

[0075] Furthermore, when the heat dissipation slot 5 is half extended, one side of the other half of the heat dissipation slot 5 is blocked by the power supply housing 1. When the airflow blows toward the blocked position, the air flow will be affected, and the poor air flow may cause dust to accumulate inside the heat dissipation hole.

[0076] Furthermore, the present invention arranges a sliding member inside the heat dissipation slot 5. Under the pushing action of the first spring 11, the sliding member drives the shielding belt 12 to shield the heat dissipation slot 5. When the heat dissipation box 2 and the heat dissipation slot 5 move outward, the movement of the sliding member can be limited by the blocking of the limiting mechanism, so that the shielding belt 12 only blocks the position where the heat dissipation slot 5 is not extended, thereby preventing airflow from entering the position where the heat dissipation slot 5 is not extended, causing dust accumulation, and affecting the heat dissipation effect during use.

[0077] As a further embodiment of the present invention, the sliding member comprises:

[0078] A fixing portion 10, the fixing portion 10 is slidably connected to the heat dissipation slot 5;

[0079] The movable part 15 is inserted into the fixed part 10, and its extension length is adjusted by a push-pull member;

[0080] One end of the first spring 11 is fixed to the surface of the fixing portion 10, and the other end of the first spring 11 is fixed to the inner wall of the heat dissipation slot 5;

[0081] One end of the shielding belt 12 away from the winding device is fixed to the movable part 15 and is located at the edge of the movable part 15 away from the fixed part 10;

[0082] An angle sensor, the angle sensor is connected to the reel of the reel device 16, and the angle sensor is used to detect the number of rotations of the reel to determine whether the surface of the shielding tape 12 is concave;

[0083] When the shielding belt 12 is recessed, the controller is also used to control the movable portion 15 to retract into the interior of the fixed portion 10, so that the shielding belt 12 is tilted;

[0084] It should be noted that the push-pull member may be a micro electric cylinder, which is a prior art and is not shown in the figure;

[0085] For example, when the heat sink 5 is half extended, the extended length of the shielding belt 12 is determined, and the number of rotations of the reel of the reel device 16 is determined. If the airflow blown by the fan is too large, the shielding belt 12 will be concave inward, thereby causing the shielding belt 12 to extend, and the number of rotations of the reel of the reel 16 will increase. The number of rotations of the reel of the reel 16 is detected by the angle sensor to determine whether the shielding belt 12 is concave;

[0086] When the shielding strip 12 is recessed, the push-pull member is activated to pull the movable portion 15 to retract into the fixed portion 10, so that the shielding strip 12 is tilted as a whole. On the one hand, the airflow can be guided to reduce the degree of recess, thereby avoiding dust accumulation in the recessed position. On the other hand, guiding the airflow is beneficial to improving the heat dissipation efficiency of the heat dissipation slot 5.

[0087] As a further embodiment of the present invention, the fan assembly comprises:

[0088] A plurality of cooling fans 17, wherein the plurality of cooling fans 17 are rotatably connected to the inside of the cooling box 2;

[0089] Motor 18, motor 18 is fixed at the bottom of the heat dissipation box 2, and the output shaft of motor 18 is coaxially fixed with the rotating shaft of the outer frame of the heat dissipation fan 17;

[0090] The cooling fan 17 is started to discharge the airflow inside the power supply housing 1. The motor 18 is further started to adjust the angle of the outer frame of the cooling fan 17 so that the cooling fan 17 is tilted to blow toward the new cooling slots 5 on both sides. Since the new cooling slots 5 do not have dust accumulation and other problems, the cooling efficiency is improved by changing the wind direction.

[0091] Furthermore, when the cooling fan 17 changes the wind direction, the wind force blowing toward the shielding belt 12 may increase, which may have an adverse effect on the shielding belt 12 in the inclined state, and then the number of rotations of the winding shaft of the winding device 16 can be detected in real time by the angle sensor. When the cooling fan 17 changes the wind direction, if the number of rotations increases, it means that the shielding belt 12 has an adverse effect. At this time, the cooling fan 17 can be controlled to slowly reset by starting the motor 18 until the number of rotations of the winding shaft of the winding device 16 returns to the set value, and the resetting of the cooling fan 17 is stopped. At this time, the wind direction of the cooling fan 17 is balanced with the shielding belt 12, which will not have an adverse effect on the shielding of the shielding belt 12, and can ensure that part of the airflow flows directly out of the new heat dissipation slot 5;

[0092] The specific steps of adjusting the inclination angle of the outer frame of the cooling fan 17 according to the concave degree of the shielding belt 12 are as follows;

[0093] Obtaining the rotation circle value of the winding shaft of the winding device 16;

[0094] When the rotation circle value is greater than the set circle value, it is determined that the shielding belt 12 is sunken;

[0095] When the shielding belt 12 is sunken, the cooling fan 17 is controlled to move in the reset direction;

[0096] Obtain the rotation circle value of the winding shaft of the winding device 16 in real time;

[0097] When the rotation circle value decreases to the set circle value, the cooling fan 17 is controlled to stop moving in the reset direction.

[0098] As a further embodiment of the present invention, the pushing assembly comprises:

[0099] A pressure sensor 19, which is fixed on the surface of the heat sink 2, and is used to detect whether there are obstacles in the outside world;

[0100] An electric push rod 20, the electric push rod 20 is fixed inside the power supply housing 1, and a second spring 21 is provided between the movable end of the electric push rod 20 and the pressure sensor 19;

[0101] In the process of the electric push rod 20 pushing the heat sink 2 to move outward, there may be external obstacles, resulting in the situation that the push cannot be made. At this time, under the blocking effect of the external obstacles, the second spring 21 will be compressed during the pushing process of the electric push rod 20, and the pressure sensor 19 detects the pressure value of the second spring 21. When the pressure value reaches the set value, it is determined that there is an external obstacle.

[0102] When the power supply urgently needs to discharge the internal heat, and there are obstacles in the outside world, the new heat dissipation slot 5 is difficult to be activated. Therefore, the present invention also proposes the following implementation mode, a strip-shaped through hole 22 is opened on the side wall of the power supply housing 1, and when there are obstacles in the outside world, the controller is used to adjust the position of the heat dissipation box 2 so that the heat dissipation slot 5 is connected with the strip-shaped through hole 22;

[0103] By connecting the heat dissipation slot 5 with the strip-shaped through hole 22, it is ensured that the high-temperature gas inside the power supply housing 1 can be discharged from the side, and the front side of the power supply housing 1 is in an open state, so that part of the heat can also be discharged;

[0104] Furthermore, in order to prevent dust from entering, a dust cover can be set on the outside of the heat dissipation box 2, and the dust cover can be fixed on the power supply housing 1. When the heat dissipation box 2 is retracted inward, the dust cover can cover the open position to prevent dust from entering.

[0105] Furthermore, the length of the heat dissipation box 2 can be lengthened so that the outer walls on both sides of the heat dissipation box 2 can extend toward the strip through hole 22 to block the entire strip through hole 22, so that the strip through hole 22 is in a closed state under normal circumstances, thereby reducing the adverse effect of the strip through hole 22 on the flow direction of the airflow inside the power supply housing 1.

[0106] like Fig.13 A control method for a UPS power supply overheat protection device is shown, and the control method comprises the following steps:

[0107] Acquiring overheating information detected by the temperature sensor 9;

[0108] According to the overheating information, the rotating column 4 is first controlled to rotate, so that the heat dissipation slot 5 is flipped from a vertical state to a horizontal state, so that the heat dissipation slot 5 is exposed and connected to the outside, and then the pushing component is started to push the heat dissipation box 2 to move outward;

[0109] Obtaining obstruction information detected by the pressure sensor 19;

[0110] According to the blocking information, the heat dissipation box 2 is controlled to move backward and communicate with the strip-shaped through hole 22;

[0111] When overheating is detected, the heat dissipation area can be increased by pushing the heat dissipation box 2 outward, thereby facilitating lowering the temperature inside the power supply housing 1;

[0112] When the pressure is too high, it means that an obstacle is encountered in the process of pushing the heat dissipation box 2 outward, so the heat dissipation box 2 is controlled to move backward to dissipate heat from the side;

[0113] The purpose of first controlling the rotation of the rotating column 4 and then controlling the heat sink 2 to move outward is to make the second electric cylinder 14 flip to a horizontal state together with the heat sink 5 first, and be on the same horizontal plane as the positioning groove 13, so as to facilitate the positioning of the sliding part through the cooperation of the second electric cylinder 14 and the positioning groove 13 during the extension of the heat sink 5.

[0114] As a further embodiment of the present invention, the specific steps of the temperature sensor 9 detecting overheating information include:

[0115] Obtaining the temperature value inside the power supply housing 1;

[0116] When the temperature reaches the set value, overheat information is generated;

[0117] Send overheat information to the controller.

[0118] As a further embodiment of the present invention, the specific steps of the pressure sensor 19 detecting the obstruction information include:

[0119] Obtaining the pressure value of the second spring 21;

[0120] When the pressure value reaches the set value, the obstacle information is generated;

[0121] Send obstacle information to the controller.

[0122] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
