Description

Technical Field

[0001] The present invention relates to the technical field of rectifiers, and in particular to a noise reduction rectifier. Background Art

[0002] A rectifier is a rectifying device, which is simply a device that converts AC into DC. It has two main functions: first, to convert AC into DC; second, to provide charging voltage to the battery.

[0003] When the noise reduction rectifier is working, it not only converts AC power into DC power, but also allows specific frequency components in the signal to pass through, while greatly attenuating other frequency components, so as to filter out interference noise. The noise reduction rectifier will generate a certain amount of heat during operation. The noise reduction rectifier is usually cooled by air, which will cause dust to adhere to the circuit board inside the noise reduction rectifier. Dust easily absorbs moisture. After the dust absorbs moisture, the resistance of the dust decreases and it can conduct electricity. This may cause a short circuit in the circuit board, causing local leakage of the circuit board, resulting in abnormal operation of the noise reduction rectifier or even heat and fire.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1 to 6 The present invention provides a noise reduction rectifier, and the technical solution is as follows:

[0035] A noise reduction rectifier, comprising:

[0036] The housing 1 has a circuit board 3 fixedly mounted inside it, and the housing 1 is a closed type;

[0037] A mounting plate 2, the mounting plate 2 is fixedly connected to the bottom of the housing 1;

[0038] Wiring ports 4: Multiple wiring ports 4 are provided on one side of the housing 1. The multiple wiring ports 4 are fixedly connected to the housing 1 and are electrically connected to the circuit board 3.

[0039] The cooling device is installed on the shell 1 and is used to cool the interior of the shell 1 .

[0040] During use, the mounting plate 2 is used to install the noise reduction rectifier. After installation, the noise reduction rectifier can be connected to the circuit that needs noise reduction and rectification through the wiring port 4, so that the circuit can be subjected to noise reduction and rectification. During use, after dust accumulates on the circuit board 3, the dust easily absorbs moisture, and the resistance of the dust with moisture will decrease, causing the circuit board 3 to leak electricity locally, resulting in abnormal operation of the noise reduction rectifier or even heat and fire. During use, in order to prevent dust from entering the interior of the shell 1, the shell 1 is set to a closed type, which can prevent dust from accumulating on the circuit board 3, and then the interior of the shell 1 can be cooled by a cooling device.

[0041] As an embodiment of the present invention, refer to Figure 3 The cooling device includes four cooling boxes 5 fixedly installed around the inside of the shell 1 and a spare box 6 fixedly installed above the shell 1. The cooling boxes 5 and the spare box 6 are filled with coolant. The four cooling boxes 5 are interconnected. Both sides of the spare box 6 are connected to the cooling boxes 5 through coolant pipes 7. Valves 8 are fixedly installed on the two coolant pipes 7. A water pump 9 is provided on the coolant pipe 7 away from the wiring port 4. The water pump 9 is fixedly connected to the shell 1. The capacity of the spare box 6 is greater than the total capacity of the four cooling boxes 5.

[0042] During use, the noise reduction rectifier will generate heat when working. By fixing a cooling box 5 on the four sides of the interior of the shell 1, there is coolant inside the cooling box 5. The coolant is an ethylene glycol coolant, which can absorb the heat generated by the noise reduction rectifier and effectively prevent the temperature of the noise reduction rectifier from rising rapidly. By arranging a spare box 6 on the shell 1, the spare box 6 is connected to the cooling box 5 through a coolant pipe 7, and a water pump 9 is provided on the coolant pipe 7. The water pump 9 is fixedly connected to the shell 1. When the water pump 9 is started, the cold coolant inside the spare box 6 can be replaced with the hot coolant inside the cooling box 5, and the interior of the shell 1 can be continuously cooled.

[0043] As an embodiment of the present invention, refer to Figure 3 A piston plate 12 is slidably installed inside the plurality of cooling boxes 5 and the spare box 6 .

[0044] During use, the water pump 9 will replace the cold coolant in the standby tank 6. During the replacement process, the cold coolant and the hot coolant will be mixed with each other. The temperature of the coolant after replacement is higher, which will increase the frequency of cooling liquid replacement by the water pump 9 and affect the service life of the water pump 9. By slidingly installing the piston plate 12 inside the cooling box 5 and the standby tank 6, after the water pump 9 is started, the cold coolant in the standby tank 6 is pumped into the cooling box 5. The piston plate 12 in the cooling box 5 will slide toward the side away from the coolant inlet direction under the action of the coolant pressure, pushing the internal hot coolant to flow into the standby tank 6 for cooling. By setting the piston plate 12, the cold coolant can be separated from the hot coolant, avoiding the increase in the frequency of cooling liquid replacement by the water pump 9 and affecting the service life of the water pump 9.

[0045] As an embodiment of the present invention, refer to Figure 3 A detection cylinder 10 is fixedly installed on the cooling box 5 close to the spare box 6, and a temperature sensor 11 is fixedly installed inside the detection cylinder 10. The temperature sensor 11 is electrically connected to the water pump 9.

[0046] By fixing a detection cylinder 10 on the cooling box 5 near the spare box 6 and fixing a temperature sensor 11 inside the detection cylinder 10, the temperature sensor 11 can detect the temperature of the coolant inside the cooling box 5 and is electrically connected to the water pump 9 through the temperature sensor 11.

[0047] After the temperature of the coolant inside the cooling box 5 reaches a certain level, the water pump 9 is started to replace the coolant with a lower temperature in the spare box 6 into the cooling box 5. By arranging a detection cylinder 10 on the cooling box 5, the temperature inside the shell 1 is kept within a suitable range, and automatic control of the coolant replacement is achieved, thereby improving the practicality of the noise reduction rectifier.

[0048] As an embodiment of the present invention, refer to Figure 4 、 Figure 5 A No. 1 switching rod 13 is slidably installed on the side of the spare box 6 close to the water pump 9, and a No. 2 switching rod 14 is slidably installed on the other side. A No. 1 switching cylinder 15 is fixedly installed on the position of the No. 1 switching rod 13 of the spare box 6, and a No. 2 switching cylinder 16 is fixedly installed on the position of the No. 2 switching rod 14 of the spare box 6. A reverse switch 17 is fixedly installed on the side of the No. 1 switching rod 13 away from the No. 1 switching rod, and a forward switch 18 is fixedly installed on the side of the No. 2 switching cylinder 16 away from the No. 2 switching rod 14. Reset plates 19 are fixedly installed on both the No. 1 switching rod 13 and the No. 2 switching rod 14. The two reset plates 19 are connected to the housing 1 through a No. 1 spring 20.

[0049] Since a piston plate 12 is slidably installed inside the standby box 6 and the cooling box 5, the piston plate 12 separates the cooling box 5 from the inside of the standby box 6. The water pump 9 needs two-way pumping to realize multiple exchanges of coolant in the cooling box 5 and the standby box 6. By fixedly installing the No. 1 switching cylinder 15 and the No. 2 switching cylinder 16 on the standby box 6, and providing a forward switch 18 and a reverse switch 17 inside the No. 1 switching cylinder 15 and the No. 2 switching cylinder 16, when the water pump 9 rotates forward, the water pump 9 pumps the coolant in the standby box 6 into the cooling box 5. At this time, the piston plate 12 in the standby box 6 moves toward the water pump 9, and the piston plate 12 in the cooling box 5 moves in the direction away from the water pump 9. The piston plate 12 in the standby box 6 will push the No. 1 switching rod during the movement. 13, so that the No. 1 switching rod 13 contacts the reverse switch 17 and the water pump 9 stops working. When the temperature inside the cooling box 5 rises next time, the water pump 9 reverses and the piston plate 12 moves in the opposite direction during the reversal of the water pump 9 and pushes the No. 2 switching rod 14 to contact the forward switch 18, so that the water pump 9 stops working again. When the temperature inside the cooling box 5 rises next time, the water pump 9 works in the forward direction. The temperature sensor 11 is electrically connected to the water pump 9, but can only control the start of the water pump 9, but cannot control the shutdown of the water pump 9. The shutdown of the water pump 9 is controlled by the forward switch 18 and the reverse switch 17, which can ensure the sufficient replacement of the coolant with a lower temperature and the coolant with a higher temperature, and will not cause the water pump 9 to start and shut down frequently due to temperature changes.

[0050] As an embodiment of the present invention, refer to Figure 6 A pressure detection cylinder 25 is fixedly installed on the cooling box 5, a detection plate 26 is fixedly installed inside the pressure detection cylinder 25, a power-off switch 27 is fixedly installed on the detection plate 26, and a No. 3 movable plate 28 is slidably installed inside the pressure detection cylinder 25. The No. 3 movable plate 28 is connected to the pressure detection cylinder 25 through a No. 3 spring 29.

[0051] Since the noise reduction rectifier adopts a coolant cooling structure, the coolant is a diethanol coolant, which is commonly used in solvents. If the coolant leaks, it will dissolve and damage the circuit board 3. In order to avoid the coolant leaking inside the cooling box 5 and damaging the circuit board 3, a pressure detection cylinder 25 is fixedly installed on the cooling box 5, and a No. 3 movable plate 28 is slidably installed inside the detection cylinder 10. During the water pumping process of the water pump 9, the pressure inside the cooling box 5 can be increased by increasing the pumping time delay control of the water pump 9. The No. 3 movable plate 28 is pushed by the cooling hydraulic pressure to move in the direction of the box power-off switch 27 and contact the power-off switch 27. If the cooling box 5 leaks coolant, the internal pressure of the cooling box 5 decreases, and the movable plate moves away from the power-off switch 27 under the action of the No. 3 spring 29 and cannot contact the power-off switch 27. The power-off switch 27 can be connected to a signal light. After contacting the power-off switch 27, the signal light will light up to remind people to perform fault maintenance, thereby avoiding the coolant leaking inside the cooling box 5 and damaging the circuit board 3.

[0052] As an embodiment of the present invention, refer to Figure 1 The cooling box 5 and the spare box 6 are both fixedly installed with a pressure relief cylinder 32. The cooling box 5, the spare box 6 and the pressure relief cylinder 32 are all connected through a pressure relief pipe 33. A No. 1 pressure relief valve 34 is fixedly installed on the pressure relief pipe 33.

[0053] During use, the coolant will vaporize due to heat, causing the pressure inside the cooling water tank and the spare water tank to increase, which may easily damage the internal parts. A pressure relief cylinder 32 is fixedly installed on the cooling box 5 and the spare box 6, and the cooling box 5, the spare box 6 and the pressure relief cylinder 32 are connected by a pressure relief pipe 33. A No. 1 pressure relief valve 34 is fixedly installed on the pressure relief pipe 33. When the pressure inside the spare box 6 and the cooling box 5 increases due to the vaporization of the coolant, part of the coolant will pass through the No. 1 pressure relief valve 34 into the pressure relief cylinder 32, thereby reducing the internal pressure of the cooling box 5 and the spare box 6.

[0054] As an embodiment of the present invention, refer to Figure 1 The two pressure relief cylinders 32 are both slidably installed with energy storage plates 35, and energy storage springs 36 are connected between the energy storage plates 35 and the pressure relief cylinders 32. The cooling box 5, the spare box 6 and the pressure relief cylinders 32 are all connected through a return pipe 37, and a No. 2 pressure relief valve 30 is fixedly installed on the return pipe 37.

[0055] By setting a No. 1 pressure relief valve 34, the coolant is introduced into the pressure relief cylinder 32 to reduce the internal pressure of the cooling box 5 and the standby box 6. The vaporized coolant will be liquefied again. Since some of the coolant enters the pressure relief cylinder 32 and cannot flow back, this will cause the pressure inside the cooling box 5 and the standby box 6 to decrease. By connecting a return pipe 37 between the pressure relief cylinder 32 and the cooling box 5 and the standby box 6, and fixing the No. 2 pressure relief valve 30 on the return pipe 37, an energy storage plate 35 is slid inside the pressure relief cylinder 32, and the energy storage plate 35 is connected to the pressure relief cylinder 32 through an energy storage spring 36. The coolant entering the pressure relief cylinder 32 will be squeezed by the energy storage plate 35. When the internal pressure of the cooling box 5 and the standby box 6 is lower than the internal pressure of the pressure relief cylinder 32, the pressure relief cylinder 32 will be squeezed by the energy storage plate 35 and flow back into the standby box 6 or the cooling box 5, thereby ensuring the stability of the internal pressure of the cooling box 5 and the standby box 6.

[0056] As an embodiment of the present invention, refer to Figure 1 A partition box 21 is fixedly installed on the outside of the spare box 6, a heat dissipation motor 22 is fixedly installed above the partition box 21, a heat dissipation fan 23 is fixedly installed at the output end of the heat dissipation motor 22, and a plurality of ventilation holes 24 are opened on the partition box 21; air outlets are provided on both sides of the heat dissipation motor 22 above the partition box 21.

[0057] When in use, the heat dissipation motor 22 starts and drives the heat dissipation fan 23 to rotate to extract the hot air inside the compartment 21. By opening a plurality of ventilation holes 24 on the compartment 21, external cold air enters the compartment 21 to cool the spare box 6. After absorbing heat, the cold air is extracted from the air outlet through the heat dissipation fan 23 on the compartment 21 and flows to the outside, so that a continuous flow of air is formed inside the compartment 21, exerting a wind cooling effect, thereby improving the cooling effect of the noise reduction rectifier.

[0058] As an embodiment of the present invention, refer to Figure 1 An isolation frame 31 is provided between the compartment box 21 and the shell 1 , and the isolation frame 31 is used to fix the compartment box 21 on the shell 1 , and the ventilation hole 24 is located below the compartment box 21 .

[0059] By supporting the partition box 21 with an isolation frame 31 and opening the ventilation holes 24 under the partition box 21, the density of the air inside the partition box 21 after absorbing heat is lower than the cold air outside the partition box 21, so that the hot air inside the partition box 21 floats above the partition box 21, and the cold air enters from the bottom of the partition box 21, thereby preventing the hot air from accumulating inside the partition box 21, which is more conducive to the heat dissipation of the spare box 6.

[0060] Working principle: When in use, after the temperature of the coolant inside the cooling box 5 reaches a certain height, the water pump 9 is started to replace the cold coolant inside the standby box 6 with the hot coolant inside the cooling box 5. When the water pump 9 rotates forward, the water pump 9 pumps the coolant in the standby box 6 into the cooling box 5. At this time, the piston plate 12 in the standby box 6 moves toward the water pump 9, and the piston plate 12 in the cooling box 5 moves away from the water pump 9. The piston plate 12 in the standby box 6 will push the No. 1 switching rod 13 during the movement, so that the No. 1 switching rod 13 contacts the reversal switch 17 and the water pump 9 stops working. When the temperature inside the cooling box 5 rises next time, the water pump 9 reverses and the piston plate 12 will move in the opposite direction during the reversal of the water pump 9 and push the No. 2 switching rod 13 to contact the reversal switch 17. The No. 1 switching rod 14 contacts the forward switch 18, causing the water pump 9 to stop working again. The next time the temperature inside the cooling box 5 rises, the water pump 9 will work in the forward direction. A reset plate 19 is set on the No. 1 switching rod 13 and the No. 2 switching rod 14, and the reset plate 19 is connected to the housing 1 through the No. 1 spring 20. After the piston plate 12 no longer pushes the No. 1 switching rod 13 and the No. 2 switching rod 14, it can be reset by the No. 1 spring 20. When the water pump 9 rotates forward, the water pump 9 draws the coolant in the standby tank 6 into the cooling box 5. At this time, the piston plate 12 in the standby tank 6 moves toward the water pump 9, and the piston plate 12 in the cooling box 5 moves in the direction away from the water pump 9. The piston plate 12 in the standby tank 6 will push the No. 1 switching rod 1 during the movement. 3. The No. 1 switching rod 13 contacts the reverse switch 17 and the water pump 9 stops working. When the temperature inside the cooling box 5 rises next time, the water pump 9 reverses and the piston plate 12 moves in the reverse direction during the reversal of the water pump 9 and pushes the No. 2 switching rod 14 to contact the forward switch 18, so that the water pump 9 stops working again. When the temperature inside the cooling box 5 rises next time, the water pump 9 works in the forward direction. A reset plate 19 is provided on the No. 1 switching rod 13 and the No. 2 switching rod 14, and the reset plate 19 is connected to the housing 1 through the No. 1 spring 20. After the piston plate 12 no longer pushes the No. 1 switching rod 13 and the No. 2 switching rod 14, it can be reset by the No. 1 spring 20. During the pumping process of the water pump 9, the pumping time of the water pump 9 can be increased by delay control to make the cooling box 5 internal pressure increases, through the cooling hydraulic pressure push No. 3 movable plate 28 box power switch 27 direction movement and contact with the power switch 27, if the cooling box 5 leaks coolant, the cooling box 5 internal pressure decreases, the movable plate under the action of No. 3 spring 29 moves in the direction away from the power switch 27 and cannot contact with the power switch 27, the power switch 27 can be connected to a signal light, after contacting the power switch 27, the signal light lights up to remind people to perform fault maintenance, during use, the coolant will be gasified by heat, resulting in increased pressure inside the cooling water tank and the spare water tank, which can easily damage the internal parts, by fixedly installing a pressure relief cylinder 32 on the cooling box 5 and the spare tank 6, the cooling box 5, the spare tank 6 and the pressure relief cylinder 32 are connected by a pressure relief pipe 33,A No. 1 pressure relief valve 34 is fixedly installed on the pressure relief pipe 33. When the pressure inside the standby tank 6 and the cooling tank 5 increases due to the gasification of the coolant, part of the coolant will pass through the No. 1 pressure relief valve 34 into the pressure relief cylinder 32, thereby reducing the internal pressure of the cooling tank 5 and the standby tank 6. A return pipe 37 is connected between the pressure relief cylinder 32 and the cooling tank 5 and the standby tank 6, and a No. 2 pressure relief valve 30 is fixedly installed on the return pipe 37. An energy storage plate 35 is slid inside the pressure relief cylinder 32. The energy storage plate 35 is connected to the pressure relief cylinder 32 through an energy storage spring 36, and the coolant enters the pressure relief cylinder 32. The energy storage plate 35 squeezes the cooling box 5 and the standby box 6. When the pressure inside the pressure relief tube 32 is lower than the pressure inside the pressure relief tube 32, the pressure relief tube 32 squeezes the energy storage plate 35 back into the standby box 6 or the cooling box 5, thereby ensuring the internal pressure of the cooling box 5 and the standby box 6 is stable. The heat dissipation motor 22 starts, and the hot air inside the compartment 21 is drawn out through the heat dissipation fan 23 on the compartment 21. The cold air enters the compartment 21 through the ventilation holes 24 below the compartment 21, forming a continuous flow of air inside the compartment 21, exerting a wind cooling effect, thereby improving the cooling effect of the noise reduction rectifier.
