Embedded energy-saving and cooling UPS power supply

Abstract

The present invention discloses an embedded energy-saving and cooling UPS power supply, comprising a shell, on which are respectively provided: a circuit assembly, which comprises a first circuit board arranged on the central axis of the shell; a battery assembly, which comprises a battery compartment symmetrically and movably arranged along the first circuit board; and a cooling mechanism. In the embedded energy-saving and cooling UPS power supply provided by the present invention, the battery compartment is symmetrically arranged along the first circuit board. When the battery is not working and the first circuit board is performing sine wave inversion operation, the fan group draws air at a low flow rate to dissipate heat for the first circuit board alone. When power is off and power is on, the battery will charge and discharge in the battery compartment. At this time, the fan group draws air at a high flow rate, so that the airflow passes through the first circuit board while the auxiliary suction groove is opened to draw air from the battery compartment to dissipate heat for the battery. The two working states can provide targeted protection for the battery while reducing the power of the fan group to achieve energy saving.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0042] like Figure 1-13 As shown, an embedded energy-saving and cooling UPS power supply includes a housing 1, and the housing 1 is respectively provided with:

[0043] The circuit assembly 2 includes a first circuit board 40 disposed on the central axis of the housing 1;

[0044] The battery assembly 3 includes a battery compartment 31 symmetrically arranged along the first circuit board 40;

[0045] The cooling mechanism 4 includes a barrier sheet 41 covered on the first circuit board 40, a fan group 15 is provided at a first end of the barrier sheet 41, and an auxiliary suction groove 43 facing the battery compartment 31 is provided on the barrier sheet 41;

[0046] The auxiliary suction trough 43 is assembled at the following two stations:

[0047] First station: the fan group 15 draws air at a low flow rate, the auxiliary suction slot 43 is closed, and the air flows along the first circuit board 40 to the fan group 15;

[0048] Second station: the fan group 15 draws air at a high flow rate, the auxiliary suction slot 43 is open, and the air flows along the first circuit board 40 and the battery compartment 31 toward the fan group 15 .

[0049] Specifically, the first circuit board 40 is mainly provided with a transformer with relatively large heat generation, a sine wave inverter circuit and a heat sink, which generates relatively large heat during operation. The barrier sheet 41 covers the first circuit board 40. When the fan group 15 is exhausting air, the external airflow will be restricted by the barrier sheet 41 to flow along the first circuit board 40 for targeted heat dissipation. The auxiliary suction groove 43 is fixedly connected to the battery compartment 31. A battery is arranged in the battery compartment 31. The fan group 15 is composed of a plurality of fans. The switching between low flow and high flow is controlled by the change in the number of fan rotations. When the power is not cut off and the battery is fully charged, the connection is individually The device is powered by the fan group 15, and the battery is not working at this time. The fan group 15 is in a low-flow mode for exhaust. At this time, the auxiliary suction groove 43 is closed, and the external airflow only passes through the first circuit board 40 to dissipate heat for the first circuit board 40 alone. When the power is off and then powered on, the battery and the first circuit board 40 both work, and the fan group 15 exhausts air at a high flow rate, which will drive the auxiliary suction groove 43 to open, causing the airflow to flow from the outside to the first circuit board 40 and the battery compartment 31. The airflow in the battery compartment 31 enters the first circuit board 40 through the auxiliary suction groove 43, and is finally discharged from the fan group 15 for heat dissipation.

[0050] A back plate 10 is disposed on the housing 1 , and a circuit board 16 and a fan assembly 15 are disposed on the back plate 10 .

[0051] In the above technical solution, the battery compartment 31 is symmetrically arranged along the first circuit board 40. When the battery is not working and the first circuit board 40 is performing sine wave inversion operation, the fan group 15 draws air at a low flow rate to dissipate heat for the first circuit board 40 alone. When power is off or on, the battery will be charged and discharged in the battery compartment 31. At this time, the fan group 15 draws air at a high flow rate, so that the airflow passes through the first circuit board 40. At the same time, the auxiliary suction groove 43 is opened to draw air from the battery compartment 31 to dissipate heat for the battery. The two working states can provide targeted protection for the battery while reducing the power of the fan group 15 to achieve energy saving.

[0052] As an embodiment provided by the present invention, a first sealing plate 11 and a second sealing plate 12 are respectively provided on the top and bottom of the shell 1, and second heat dissipation holes 112 are opened in a linear array on the first sealing plate 11. A movable part 42 is provided on the barrier sheet 41. The movable part 42 slides along the first sealing plate 11 to seal or open the second heat dissipation holes 112 as the work station is switched.

[0053] Specifically, the first sealing plate 11 and the second sealing plate 12 are both provided with a first heat dissipation hole 111, and the first heat dissipation hole 111 is used to allow external airflow to flow into the battery compartment 31. The movable portion 42 is in a bent state, and the end of the movable portion 42 (with Figure 8 For reference, the end is the upper end) is an elastic sheet that fits the first blocking plate 11. In the low flow mode, the suction force generated by the fan group 15 is small, and the exhaust direction tends to the central axis of the fan group 15. At this time, the movable part 42 on the blocking sheet 41 will not be obviously deformed, and the second heat dissipation hole 112 is in a fully open state to dissipate heat for the first circuit board 40 alone. In the high flow mode, the fan group 15 is opened as a whole for exhaust. At this time, the movable part 42 will be deformed to move and block part of the second heat dissipation hole 112 to enhance the deformation of the movable part 42 to drive the auxiliary suction groove 43 to open.

[0054] When the battery is not working, the fan group 15 is in a low-flow mode for exhaust. At this time, the movable part 42 will not be obviously deformed, the auxiliary suction groove 43 is closed, and the external airflow passes through the first circuit board 40 along the second heat dissipation hole 112 to dissipate heat for the first circuit board 40 alone. When the battery and the first circuit board 40 are both working, the fan group 15 performs high-flow exhaust, the movable part 42 will be deformed to move, and partially block the second heat dissipation holes 112, and will drive the auxiliary suction groove 43 to open, causing airflow to flow from the outside to the first circuit board 40 and the battery compartment 31. The airflow in the battery compartment 31 will enter the first circuit board 40 through the auxiliary suction groove 43, and finally be discharged from the fan group 15 for heat dissipation.

[0055] As an embodiment provided by the present invention, a sealing plate 46 for sealing the auxiliary suction groove 43 is provided on the housing 1, and the blocking sheet 41 is switched and deformed with the workstation to drive the auxiliary suction groove 43 and the sealing plate 46 to move away from each other.

[0056] Specifically, a fixed seam strip 45 is provided on the shell 1, and the sealing plate 46 and the barrier sheet 41 are both fixed on the fixed seam strip 45. The sealing plate 46 is fixed and is used to limit the maximum expansion range of the barrier sheet 41. When the fan group 15 is at low power, the barrier sheet 41 does not deform. At this time, the auxiliary suction groove 43 is blocked by the sealing plate 46. When the fan group 15 is at high power, the barrier sheet 41 is deformed. At this time, the sealing plate 46 is separated from the barrier sheet 41 to generate a gap opening to connect the battery compartment 31. When opening, the deformation force of the barrier sheet 41 due to the suction negative pressure is reduced, but the second heat dissipation hole 112 will be blocked to increase the negative pressure deformation force to avoid the heavy sealing plate 46 and the barrier sheet 41 Separation to generate a gap closed for a long time.

[0057] When the battery is not working, the fan group 15 is in a low-flow mode for exhaust. At this time, the movable part 42 will not be obviously deformed, the auxiliary suction groove 43 is closed by fitting the sealing plate 46, and the external airflow passes through the first circuit board 40 along the second heat dissipation hole 112 to dissipate heat for the first circuit board 40 alone. When the battery and the first circuit board 40 are both working, the fan group 15 performs high-flow exhaust, the movable part 42 will be deformed to move, and partially block the second heat dissipation hole 112, and will drive the sealing plate 46 to separate from the auxiliary suction groove 43 to create a gap opening, causing airflow to flow from the outside to the first circuit board 40 and the battery compartment 31, and the airflow in the battery compartment 31 will enter the first circuit board 40 through the auxiliary suction groove 43, and finally be discharged from the fan group 15 for heat dissipation.

[0058] As an embodiment provided by the present invention, an air alignment groove 312 is provided on the battery compartment 31. The air alignment groove 312 is misaligned with the auxiliary suction groove 43 when the battery compartment 31 is installed upright, and overlaps with the auxiliary suction groove 43 when the battery compartment 31 is installed reversely.

[0059] The air groove 312 is opened at the bottom of the battery compartment 31 , and a guide channel is formed between the battery compartment 31 and the barrier sheet 41 , and the airflow passes through the guide channel along the battery compartment 31 .

[0060] Specifically, there is a gap between the battery compartment 31 and the barrier sheet 41 (the gap is 8mm-16mm), and the air groove 312 is opened at the bottom of the battery compartment 31. When there is a timed power-off in the working mode of the device (the timed power-off is to turn off the main power at a fixed time every day, several days or every week, and start the standby work), the battery compartment 31 is installed upright. At this time, the external airflow will enter from the top of the battery compartment 31 to cool the battery, and then enter the guide space along the air groove 312. Because the battery compartment 31 is installed upright, the air groove 312 and the auxiliary The suction groove 43 is staggered to extend the time of the airflow in the guide channel to increase the cooling of the battery compartment 31. In the working mode of the device, there is a long-term operation situation (that is, when the power is rarely actively cut off, the battery can be recharged after a slight leakage, resulting in a short battery activation time). The battery compartment 31 is reversed and installed on the shell 1. At this time, the air groove 312 and the auxiliary suction groove 43 overlap. At this time, the external airflow will directly enter the auxiliary suction groove 43 after entering the battery compartment 31, and does not need to pass through the entire guide channel to reduce the cooling of the battery compartment 31.

[0061] First, according to the working conditions of the equipment, the battery compartment 31 is installed forward or reverse. When the battery is not working, the fan group 15 is in low-flow mode for exhaust. At this time, the movable part 42 will not be obviously deformed, and the auxiliary suction groove 43 is closed by fitting the sealing plate 46. The external airflow passes through the first circuit board 40 along the second heat dissipation hole 112 to dissipate heat for the first circuit board 40 alone. When the battery and the first circuit board 40 are both working, the fan group 15 performs high-flow exhaust. The movable part 42 will be deformed to move and block part of the second heat dissipation hole 112. The sealing plate 46 will be driven to separate from the auxiliary suction groove 43 to create a gap opening, causing airflow to flow from the outside to the first circuit board 40 and the battery compartment 31. The airflow in the battery compartment 31 will enter the first circuit board 40 through the auxiliary suction groove 43 and finally be discharged from the fan group 15 for heat dissipation.

[0062] As an embodiment provided by the present invention, the circuit assembly 2 also includes a second circuit board 401 arranged along the central axis of the shell 1, and a bending portion 411 is provided on the barrier sheet 41 to divide the second circuit board 401 and the first circuit board 40 into a second channel 4001 and a first channel 400 respectively, and the fan group 15 is arranged on the first channel 400.

[0063] Specifically, the second circuit board 401 and the first circuit board 40 are coaxially arranged, and the second circuit board 401 is provided with a synchronous sampling circuit, an EMI filter circuit, etc. with low heat generation, and a bending portion 411 is provided on the barrier sheet 41 to separate the second circuit board 401 and the first circuit board 40 into a second channel 4001 and a first channel 400, so as to specifically cool the first circuit board 40 with higher heat generation, while the second circuit board 401 with lower heat generation can be cooled with the help of the barrier sheet 41.

[0064] First, according to the working conditions of the equipment, the battery compartment 31 is installed forward or reverse. When the battery is not working, the fan group 15 is in low-flow mode for exhaust. At this time, the movable part 42 will not be obviously deformed, and the auxiliary suction groove 43 is closed in contact with the sealing plate 46. The external airflow passes through the first channel 400 along the second heat dissipation hole 112 to dissipate heat for the first circuit board 40 alone. When the battery and the first circuit board 40 are both working, the fan group 15 performs high-flow exhaust, the movable part 42 will be deformed to move, and partially block the second heat dissipation hole 112, and will drive the sealing plate 46 to separate from the auxiliary suction groove 43 to create a gap opening, causing airflow to flow from the outside to the first circuit board 40 and the battery compartment 31. The airflow in the battery compartment 31 will enter the first circuit board 40 through the auxiliary suction groove 43, and finally be discharged from the fan group 15 for heat dissipation, while the second circuit board 401 in the second channel 4001 is cooled by heat conduction with the aid of the barrier sheet 41.

[0065] As an embodiment provided by the present invention, the second channel 4001 is assembled at the following two stations:

[0066] The third station: the first channel 400 is sucked and blocked by the second channel 4001;

[0067] Fourth station: the first channel 400 sucks the second channel 4001 connected to the battery compartment 31;

[0068] The first channel 400 is fixedly connected to an inclined air channel 44 directed toward the second channel 4001 . The direction of the inclined air channel 44 is opposite to the airflow direction in the first channel 400 .

[0069] Specifically, when the second circuit board 401, which does not generate much heat, is used for a long period of time without power outage, it is prone to aging, and electric sparks will appear during aging. At this time, the second channel 4001 is switched to the third station to allow the first channel 400 to suck and block the second channel 4001, so that negative pressure is generated in the second channel 4001 to avoid combustion and diffusion after the electric sparks emerge. When the second circuit board 401 is powered off at a fixed time, electric sparks are not likely to appear, so the second channel 4001 is switched to the fourth station to allow airflow to flow along the second channel 4001 to cool the second circuit board 401 during use, so as to extend the service life of the second circuit board 401.

[0070] Since the size of the inclined air channel 44 is smaller than that of the first channel 400 , when the airflow in the first channel 400 flows, the inclined air channel 44 will suck the airflow in the second channel 4001 along with the airflow.

[0071] First, the battery compartment 31 is installed forward or reversely according to the working condition of the device. When the battery is not working, the fan group 15 is in a low-flow mode for exhaust. At this time, the movable part 42 will not be significantly deformed, the auxiliary suction groove 43 is closed by fitting the sealing plate 46, and the external airflow passes through the first channel 400 along the second heat dissipation hole 112 to dissipate heat to the first circuit board 40 alone. When the battery and the first circuit board 40 are both working, the fan group 15 performs high-flow exhaust, the movable part 42 will be deformed to move, and partially block the second heat dissipation hole 112. It will also drive the sealing plate 46 to separate from the auxiliary suction groove 43 to create an open gap, causing airflow to flow from the outside to the first circuit board 40 and the battery compartment 31. The airflow in the battery compartment 31 will enter the first circuit board 40 through the auxiliary suction groove 43 and eventually be discharged from the fan group 15 to dissipate heat. The second circuit board 401 in the second channel 4001 is cooled by heat conduction through the barrier sheet 41. When the power is not cut off for a long time, the second channel 4001 is switched to the third station. When the power is cut off for a time, the second channel 4001 is switched to the fourth station.

[0072] As an embodiment provided by the present invention, the second channel 4001 is installed forward or reversely with the battery compartment 31 so that the battery compartment 31 is connected to or blocks the second channel 4001 .

[0073] Specifically, the work station switching of the second channel 4001 is controlled by the normal or reverse installation of the battery compartment 31. The normal installation of the battery compartment 31 corresponds to a timed power outage. The fourth work station of the second channel 4001 corresponds to the normal installation of the battery compartment 31, and the reverse installation of the battery compartment 31 corresponds to the third work station of the second channel 4001, so as to cope with the situation of continuous operation.

[0074] First, the battery compartment 31 is installed forward or reversely according to the working condition of the device. When the battery is not working, the fan group 15 is in a low-flow mode for exhaust. At this time, the movable part 42 will not be significantly deformed, the auxiliary suction groove 43 is closed in contact with the sealing plate 46, and the external airflow passes through the first channel 400 along the second heat dissipation hole 112 to dissipate heat to the first circuit board 40 alone. When the battery and the first circuit board 40 are both working, the fan group 15 performs high-flow exhaust, the movable part 42 will be deformed to move, and partially block the second heat dissipation hole 112, and drive the sealing plate 46 and The auxiliary suction groove 43 is separated to create an open gap, causing airflow to flow from the outside to the first circuit board 40 and the battery compartment 31. The airflow in the battery compartment 31 enters the first circuit board 40 through the auxiliary suction groove 43 and is finally discharged from the fan group 15 to dissipate heat. The second circuit board 401 in the second channel 4001 is cooled by heat conduction with the help of the barrier sheet 41. When the battery compartment 31 is reversed and the power is not cut off for a long time, the second channel 4001 is switched to the third position and the battery compartment 31 is installed normally. When the power is off for a timed period, the second channel 4001 is switched to the fourth position.

[0075] As the optimal embodiment provided by the present invention, a ventilation groove 510 is opened on the second channel 4001, an elastic plate 511 is arranged on the ventilation groove 510, an opening groove 311 is opened on the battery compartment 31, and the opening groove 311 corresponds to the ventilation groove 510 when the battery compartment 31 is installed.

[0076] Specifically, spacer plates 51 are respectively provided on both sides of the second channel 4001, and ventilation grooves 510 are opened on the spacer plates 51. Elastic plates 511 are provided on the ventilation grooves 510, and the elastic plates 511 are stretched outward from the battery compartment 31. When the battery compartment 31 is installed upright, the opening grooves 311 are correspondingly connected with the ventilation grooves 510, so that the first channel 400 can draw the second channel 4001 connected with the battery compartment 31. When the battery compartment 31 is installed reversely, the elastic plate 511 and the opening grooves 311 are misaligned, so that the ventilation grooves 510 are blocked, thereby realizing the fourth working position of the second channel 4001.

[0077] First, according to the working conditions of the device, the battery compartment 31 is installed forward or reverse. When the battery is not working, the fan group 15 is in a low-flow mode for exhaust. At this time, the movable part 42 will not be significantly deformed, the auxiliary suction groove 43 is closed by fitting the sealing plate 46, and the external airflow passes through the first channel 400 along the second heat dissipation hole 112 to dissipate heat for the first circuit board 40 alone. When the battery and the first circuit board 40 are both working, the fan group 15 performs high-flow exhaust, the movable part 42 will be deformed to move, and partially block the second heat dissipation hole 112, and will drive the sealing plate 46 to separate from the auxiliary suction groove 43 to open a gap, causing airflow to flow from the outside to the first circuit board 40 and the battery compartment 31 , the airflow in the battery compartment 31 will enter the first circuit board 40 through the auxiliary suction groove 43, and will eventually be discharged from the fan group 15 for heat dissipation, while the second circuit board 401 in the second channel 4001 is cooled by heat conduction with the help of the barrier sheet 41. When the battery compartment 31 is reversed and the power is not cut off for a long time, the second channel 4001 is switched to the third station, the elastic plate 511 and the opening groove 311 are misaligned so that the ventilation groove 510 is blocked, and the battery compartment 31 is installed normally. When the power is cut off at a fixed time, the second channel 4001 is switched to the fourth station, and the opening groove 311 is connected to the ventilation groove 510 accordingly, so that the first channel 400 can suck the second channel 4001 connected to the battery compartment 31.
