Description

Technical Field

[0001] This invention belongs to the field of charger technology, and particularly relates to a cooling and ventilation structure for a high-power charger. Background Technology

[0002] A charger is a device that converts alternating current (AC) into low-voltage direct current (DC) to charge batteries. It has a wide range of applications in various fields. The efficiency of high-power chargers is limited by their operating conditions, among which operating temperature is a crucial factor. Therefore, controlling the operating temperature of high-power chargers is an important measure to ensure their safe operation.

[0003] With the rapid development of modern society, chargers are used in more and more places, bringing great convenience to people's lives. However, existing chargers still have the following problems during use: Chargers generate a lot of heat during charging. If the charger is not cooled in time, the charger casing and power cord can easily become overheated. Over time, this high-heat working environment can reduce the performance of internal components or even damage them, thus reducing the charger's lifespan and hindering sustainable use. Furthermore, the lack of dustproof structures at the ventilation openings of existing ventilation systems allows dust to enter the charger directly through the vents during heat dissipation. Dust inside the charger also affects its heat dissipation. Therefore, these shortcomings fail to meet user needs and further improvements are necessary.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a cooling and ventilation structure for high-power chargers, in order to achieve a more practical purpose. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a cooling and ventilation structure for a high-power charger, which is achieved by the following specific technical means:

[0006] A cooling and ventilation structure for a high-power charger includes a base, a housing fixedly mounted on the upper side of the base, a controller fixedly mounted on the upper side of the base and inside the housing, a temperature sensor fixedly mounted on the upper side of the base and to the right of the controller, a cooling component for cooling the controller fixedly mounted on the right side of the housing, a mounting bracket fixedly mounted on the inner wall of the cooling component, a cooling assembly for cooling the controller fixedly mounted on the mounting bracket, a dust filter for filtering dust inside the cooling component, and a dust filter for filtering dust at the central opening.

[0007] The cooling assembly includes a dual-axis motor, a cooling fan, and a drive ratchet. The outer periphery of the dual-axis motor is fixedly mounted to the mounting bracket. The left side of the dual-axis motor is movably connected to the cooling fan via an output shaft, and the right side of the dual-axis motor is movably connected to the drive ratchet via an output shaft.

[0008] By adopting the above structure, the cooling air is drawn into the box through the ventilation holes of the dustproof plate by the force of the dual-axis motor and the cooling fan, thereby cooling the electronic components inside the controller and improving the charging efficiency of the charger.

[0009] Furthermore, the controller has input lines and output lines on its left and right sides respectively, which pass through the box and connect to the outside. The left side of the box has a control panel for controlling the controller.

[0010] By adopting the above structure, power is connected to the device via the input line and the charging port of the charging equipment is connected via the output line, enabling the charging operation of the device. The control panel can effectively control the charger, further improving its practicality.

[0011] Furthermore, a fixing seat is fixedly installed inside the cooling component and on the right side of the cooling assembly. The fixing seat has an annular structure and a groove is provided on the inner wall of the fixing seat. An elastic layer is provided on the outer edge where the dustproof net is located, and the elastic layer is fixedly connected to the inner wall of the groove of the fixing seat.

[0012] By adopting the above structure, the dustproof net can effectively block dust and impurities in the air, while the elastic layer can enhance the vibration frequency of the dustproof net.

[0013] Furthermore, a dustproof seat is provided on the inner wall of the cooling component and on the left side of the cooling assembly, and a dustproof plate is provided on the left side of the dustproof seat, with the dustproof plate in close contact with the dustproof seat.

[0014] The dustproof seat has a groove on the side facing the dustproof plate, and an elastic connector is provided inside the groove. The left side of the elastic connector is elastically connected to the dustproof plate.

[0015] By adopting the above structure, the dustproof plate is pulled back to its original position by the tension of the elastic connector, so that the dustproof plate and the dustproof seat are attached to each other and achieve a closed effect. This setting can prevent the loss of cold air on the one hand, and on the other hand, it can protect the charger equipment itself from dust, preventing dust and impurities from entering the inside of the box.

[0016] Furthermore, a cooling channel is provided in the middle of the dustproof seat, and several ventilation holes are provided on the dustproof plate. The cooling channel and ventilation holes are staggered. The cooling channel and ventilation holes are sealed and closed by the dustproof plate and the side wall of the dustproof seat being fitted together.

[0017] By adopting the above structure, the dustproof plate and the dustproof seat can be fitted together to achieve a closed effect, which can effectively prevent dust and impurities from entering the interior of the box.

[0018] Furthermore, a condenser is installed inside the dustproof seat, and a condenser tube is connected to the upper side of the condenser. The condenser tube is located in the cooling channel of the dustproof seat, and the condenser tube is driven to perform a cooling operation.

[0019] By adopting the above structure, the condenser and the condenser tube work together to generate cold air in the condenser tube. The air passing through the cooling channel drives the cold air generated by the condenser tube to be simultaneously drawn into the interior of the box, thereby further cooling the controller and achieving a powerful cooling effect, which further improves the charging efficiency of the charger.

[0020] Furthermore, a transmission assembly is provided on the inner wall of the fixed base and on the left side of the dustproof net. The transmission assembly includes a transmission shaft, a transmission ratchet, and a movable component.

[0021] The drive shaft is rotatably connected to the inner wall of the fixed base. The drive ratchet is movably mounted on the drive shaft and meshes with the drive ratchet. Several movable parts are provided, and several movable parts are fixedly mounted at the end of the drive shaft. The drive ratchet meshes with the drive ratchet and drives the drive shaft and movable parts to rotate.

[0022] By adopting the above structure, the drive ratchet and transmission ratchet mesh with each other, driving the transmission shaft and moving parts to rotate synchronously, thus achieving the effective transmission function of the structure.

[0023] Furthermore, a fixing bracket is fixedly installed on the side of the fixing base facing the cooling component, and the side of the fixing bracket facing the dustproof net is elastically connected to the vibration component through a vibration spring.

[0024] By adopting the above structure, the vibration frequency of the vibration component can be increased on the one hand, and the vibration spring can be reset on the other hand, so that the vibration component returns to its initial position after operation.

[0025] Furthermore, the vibration assembly includes a vibration seat, a vibration frame, a vibration plate, and a vibration element;

[0026] A vibration frame is fixedly installed on the side of the vibration seat away from the vibration spring. A vibration plate is fixedly installed on the side of the vibration frame away from the vibration seat. A vibration element is fixedly installed on the side of the vibration plate facing the dustproof net. The dustproof net is struck by the vibration element, causing the dustproof net to vibrate.

[0027] By adopting the above structure, the moving parts are driven by the transmission shaft to rotate, and at the same time, the vibrating seat is struck and pushed, so that the vibrating seat generates a back-and-forth vibration frequency.

[0028] Furthermore, a limiting component is fixedly provided on the inner wall of the fixed bracket, the limiting component including a limiting frame and a limiting rod;

[0029] The limiting frame is fixedly installed on the inner wall of the fixed bracket, and the limiting rod is fixedly installed on the limiting frame. The vibration frame has a movable groove, and the limiting rod is inserted into the movable groove of the vibration frame.

[0030] By adopting the above structure, the stability of the vibration component during movement can be improved by inserting the limiting rod into the movable slot of the vibration frame, while limiting its displacement and further improving its stability.

[0031] Beneficial effects

[0032] Compared with the prior art, the present invention provides a cooling and ventilation structure for a high-power charger, which has the following beneficial effects:

[0033] 1. The cooling and ventilation structure of this high-power charger uses a dual-axis motor and a cooling fan to draw cooling air into the interior of the casing through the ventilation holes of the dustproof plate. This allows for the intake of cooling air, which in turn cools the electronic components inside the controller, thereby improving the charging efficiency of the charger.

[0034] 2. The cooling and ventilation structure of this high-power charger uses the cooperation between the condenser and the condenser tube to generate cold air. The cold air generated by the condenser tube is then drawn into the interior of the casing by the air passing through the cooling channel, further cooling the controller and achieving a powerful cooling effect. This further improves the charging efficiency of the charger and provides a certain degree of protection for the controller, effectively extending the service life of the charger and facilitating sustainable use by the user.

[0035] 3. The cooling and ventilation structure of this high-power charger automatically stops the operation of the cooling components and condenser when the internal temperature of the box drops to within a certain range, based on the internal program settings. The dustproof plate is pulled back by the tension of the elastic connector, so that the dustproof plate and the dustproof seat are attached to each other to achieve a closed effect. This setting can prevent the loss of cold air on the one hand, and play a role in dust protection for the charger itself on the other hand, preventing dust and impurities from entering the interior of the box, thus further improving its applicability.

[0036] 4. The cooling and ventilation structure of this high-power charger: This device uses a dustproof net to block dust and impurities in the air. At the same time, the vibration component impacts the dustproof net, causing the net to vibrate under the action of the elastic layer. This shakes off the dust and impurities on the surface of the net, preventing them from entering the housing and accumulating on the controller surface, thus affecting the controller's heat dissipation. This design not only prevents dust and impurities from entering but also improves air penetration, which is beneficial for air circulation and heat dissipation of the charger.

Under the action of the dual-axis motor 71 and the cooling fan 72, cooling air passes through the ventilation holes 111 of the dustproof plate 11 and is drawn into the interior of the box 2, thereby cooling the electronic components inside the controller 3 and improving the charging efficiency of the charger.

The dustproof seat 10 has a groove on the side facing the dustproof plate 11, and an elastic connector 12 is provided inside the groove. The left side of the elastic connector 12 is elastically connected to the dustproof plate 11. Based on the pulling force of the elastic connector 12, the dustproof plate 11 is pulled to reset, so that the dustproof plate 11 and the dustproof seat 10 are in close contact and achieve a closed effect. This setting can prevent the loss of cold air and also protect the charger equipment itself from dust, preventing dust and impurities from entering the interior of the box 2.

[0055] A cooling channel 101 is provided in the middle of the dustproof base 10, and a number of ventilation holes 111 are provided on the dustproof plate 11. The cooling channel 101 and the ventilation holes 111 are staggered. The cooling channel 101 and the ventilation holes 111 are sealed and closed by the dustproof plate 11 and the side wall of the dustproof base 10 being attached to each other. This arrangement allows the dustproof plate 11 and the dustproof base 10 to be attached to each other to achieve a sealing effect, which can effectively prevent dust and impurities from entering the interior of the box 2.

[0056] The dustproof base 10 has a condenser 13 inside, and a condenser pipe 131 is connected to the upper side of the condenser 13. The condenser pipe 131 is located in the cooling channel 101 of the dustproof base 10. The condenser 13 is driven to make the condenser pipe 131 perform refrigeration. The condenser pipe 131 generates cold air through the cooperation between the condenser 13 and the condenser pipe 131. The cold air generated by the condenser pipe 131 is driven by the air passing through the cooling channel 101 and is synchronously drawn into the interior of the box 2 to further cool the controller 3 and achieve a strong cooling effect.

[0057] A transmission assembly 14 is provided on the inner wall of the fixed base 8 and on the left side of the dustproof net 9.

The transmission ratchet 142 is detachably mounted on the transmission shaft 141 and meshes with the drive ratchet 73. Several movable parts 143 are provided and fixedly mounted at the end of the transmission shaft 141. The drive ratchet 73 meshes with the transmission ratchet 142 and drives the transmission shaft 141 and the movable parts 143 to rotate. The drive ratchet 73 meshes with the transmission ratchet 142 and drives the transmission shaft 141 and the movable parts 143 to rotate synchronously, realizing the effective transmission function of the structure.

[0058] A fixed bracket 15 is fixedly installed on the side of the fixed base 8 facing the cooling component 7. The side of the fixed bracket 15 facing the dustproof net 9 is elastically connected to the vibration component 16 through a vibration spring 151. The vibration spring 151 can increase the vibration frequency of the vibration component 16 on the one hand, and reset it on the other hand.

The vibration plate 163 is fixedly installed on the side of the vibration frame 162 away from the vibration seat 161. The vibration element 164 is fixedly installed on the side of the vibration plate 163 facing the dustproof net 9. The vibration element 164 strikes the dustproof net 9 and causes it to vibrate.

The vibration frame 162 has a movable groove, and the limiting rod 172 is inserted into the movable groove of the vibration frame 162. By inserting the limiting rod 172 into the movable groove of the vibration frame 162, the stability of the vibration component 16 when moving can be improved, and its displacement can be limited.

[0061] A fixing seat 8 is fixedly installed inside the cooling component 6 and on the right side of the cooling assembly 7. The fixing seat 8 has a ring structure and a groove is provided on the inner wall of the fixing seat 8. An elastic layer 91 is provided on the outer edge where the dustproof net 9 is located, and the elastic layer 91 is fixedly connected to the inner wall of the groove of the fixing seat 8. The dustproof net 9 can block dust and impurities in the air, and the elastic layer 91 can enhance the vibration frequency of the dustproof net 9.

[0062] The specific usage and function of this embodiment are as follows:

[0063] Working Principle: During use, electrical energy is connected via input line 31 and the charging port of the charging device is connected via output line 32. The controller 3 performs safety checks on the circuit signals through the input detection circuit and signal detection circuit, and charges the charging device via the charging module. During prolonged charging operation, a large amount of heat is generated inside the housing 2, resulting in a high internal temperature. The temperature sensor 5 monitors the internal temperature of the housing 2. When the internal temperature reaches a certain level, the alarm module in the temperature sensor 5 triggers an overheat alarm, thereby activating the dual-axis motor 71 under program control. The dual-axis motor 71 drives the cooling fan 72 to rotate. This creates a pressure difference on the outside of the dustproof net 9, drawing external cooling air into the cooling component 6 along the dustproof net 9. Under the force of the dual-axis motor 71 and the cooling fan 72, the external cooling air passes through the cooling channel 101 and pushes the dustproof plate 11. Based on the airflow, the dustproof plate 11 is simultaneously pushed to move the elastic connector 12, causing the dustproof plate 11 to separate from the side wall of the dustproof seat 10. The cooling air passes through the gap and then through the ventilation holes 111 of the dustproof plate 11 into the interior of the box 2, thus achieving the intake of cooling air. This allows for the cooling and temperature reduction of the electronic components inside the controller 3, ensuring sufficient cooling of the controller 3 and improving the charging efficiency of the charger.

[0064] When the internal temperature of the housing 2 is high and reaches a certain high temperature, the condenser 13 is activated and runs simultaneously through the internal program settings. The condenser 13 and the condenser tube 131 work together to generate cold air. The cold air generated by the condenser tube 131 is drawn into the interior of the housing 2 by the air passing through the cooling channel 101, thereby further cooling the controller 3 and achieving a strong cooling effect. This further improves the charging efficiency of the charger and provides a certain degree of protection for the controller 3, effectively extending the service life of the charger and facilitating continuous use by the user. When the internal temperature of the housing 2 drops to within the range, the cooling component 7 and the condenser 13 automatically stop running through the internal program settings. The dustproof plate 11 is pulled back by the tension of the elastic connector 12, causing the dustproof plate 11 and the dustproof seat 10 to stick together and achieve a closed effect. This setting can prevent the loss of cold air and also protect the charger itself from dust, preventing dust and impurities from entering the interior of the housing 2.

[0065] Furthermore, as cooling air enters the cooling component 6 along the dustproof mesh 9, the filter effectively blocks dust and impurities from the air. During operation, the dual-axis motor 71 synchronously drives the drive ratchet 73 via its other output shaft. The drive ratchet 73 meshes with the transmission ratchet 142, causing the transmission shaft 141 and the moving part 143 to rotate synchronously. Simultaneously, the moving part 143 strikes and pushes the vibrating seat 161, causing it to vibrate back and forth. This vibration simultaneously pushes the vibrating component 164 into contact with the filter. By inserting the limiting rod 172 into the movable slot of the vibration frame 162, the stability of the vibration component 16 during movement can be improved, and its displacement can be limited. As the vibrating component 164 collides with the filter screen, the filter screen generates its own vibration frequency under the action of the elastic layer 91, which can shake off the dust and impurities on the surface of the filter screen, preventing them from entering the box 2 and accumulating on the surface of the controller 3, thus affecting the heat dissipation effect of the controller 3. This setting can prevent dust and impurities from entering and improve the air penetration effect, which is conducive to air circulation and heat dissipation of the charger equipment.
