Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and in particular to a fast charging terminal and its usage method. Background Technology

[0002] A fast-charging terminal, also known as a fast-charging station, is a device for quickly charging the batteries of electric two-wheelers. The fast-charging terminal includes a housing containing components such as a charging module, a control module, and a communication module. The charging module charges the electric two-wheeler's battery through a charging gun. During operation, the charging module, as a major heat-generating component, produces a significant amount of heat. Although heat can be dissipated through fans, in hot weather, a large amount of heat inevitably transfers to the control and communication modules. Overheating of the control and communication modules can affect their functionality or even cause damage. Furthermore, excessively low temperatures can also affect the performance of the control and communication modules, and may cause condensation or frost, leading to short circuits and ultimately damaging the control and communication modules. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a fast charging terminal that, in hot weather, can effectively reduce the heat generated by the charging module from being transferred to the control module and communication module, and in cold weather, can transfer the heat generated by the charging module to the control module and communication module, thus preventing the control module and communication module from being overheated or underheated, which could affect their performance or even cause damage.

[0004] This application also proposes a method for microplastic recycling filtration extraction.

[0005] According to a first aspect embodiment of this application, a fast-charging terminal includes a housing and a heat-conducting assembly. The housing is divided by two partitions to form a first mounting cavity, a heat dissipation cavity, and a second mounting cavity arranged sequentially. The first mounting cavity is used to install a charging module, and the second mounting cavity is used to install a communication module and a control module. The heat-conducting assembly includes two hot water plates and a valve assembly. The two hot water plates are respectively disposed in the first mounting cavity and the second mounting cavity, and both extend into the heat dissipation cavity. Each hot water plate has a hot water channel, and each hot water channel has a circulating water pump. The valve assembly is disposed between the two hot water plates. When the temperature in the second mounting cavity is greater than a preset value, the valve assembly disconnects the two hot water channels, forming two first circulating water channels respectively; when the temperature in the second mounting cavity is less than or equal to the preset value, the valve assembly connects the two hot water channels, forming a second circulating water channel.

[0006] The fast charging terminal according to the embodiments of this application has at least the following beneficial effects: In this application, the heat dissipation cavity is located between the first mounting cavity and the second mounting cavity. The charging module is installed in the first mounting cavity, and the communication module and control module can be installed in the second mounting cavity. The heat dissipation cavity isolates them, which can reduce direct heat transfer between the first and second mounting cavities. When the weather is hot and the temperature in the second mounting cavity exceeds a preset value, the valve assembly disconnects the two hot water channels and forms two separate first circulating water channels. Two circulating water pumps drive the water in the two first circulating water channels to circulate. When the water in the first circulating water channel in the first mounting cavity circulates, it can transfer the heat generated by the charging module to the heat dissipation cavity for dissipation. When the water in the first circulating water channel in the second mounting cavity circulates, it can transfer the heat generated by the multiple components in the second mounting cavity to the heat dissipation cavity for dissipation, thus achieving heat dissipation for each component. Moreover, the disconnection of the two hot water channels can effectively reduce the heat generated by the charging module from being transferred to the control module and communication module, avoiding the communication module and control module from overheating and affecting performance or causing damage. When the weather is cold, and the temperature inside the second mounting cavity is less than or equal to a preset value, the valve assembly connects the two hot water channels to form a second circulating water channel. The second circulating water channel passes through the first mounting cavity, the second mounting cavity, and the heat dissipation cavity, allowing the heat generated by the charging module to be transferred to the first mounting cavity. This effectively utilizes thermal energy to heat the control module and the communication module, preventing the communication module and the control module from being damaged due to excessively low temperatures. It also prevents condensation or frost from causing short circuits and damage.

[0007] According to some embodiments of this application, the valve assembly includes a docking plate and four directional valves. The docking plate has two oppositely arranged first channels and two oppositely arranged second channels, which together form a quadrilateral structure. The four directional valves are respectively located at the four corners of the quadrilateral structure. The directional valves connect adjacent first channels and second channels. The two ends of the hot water conduction channel form connection ends, and the four directional valves are respectively connected to the four connection ends. Furthermore, the two connection ends of the same hot water conduction channel are respectively connected to two adjacent directional valves.

[0012] According to some embodiments of this application, the arrangement direction of the plurality of heat sinks on the heat sink plate is perpendicular to the arrangement direction of the air vent and the cooling fan.

[0013] According to some embodiments of this application, a temperature sensor is provided in the second mounting cavity. The temperature sensor is used to detect the temperature in the second mounting cavity. The temperature sensor and the valve assembly are adapted to be connected to the control module. The control module controls the operation of the valve assembly and the circulating water pump according to the detection result of the temperature sensor.

[0014] According to some embodiments of this application, the hot water conductive plate in the first mounting cavity is configured to fit against the charging module.

[0015] The method of using a fast charging terminal according to a second aspect embodiment of this application, based on a fast charging terminal according to a first aspect embodiment of this application, includes: Detect the temperature inside the second mounting cavity; When the temperature inside the second mounting cavity is greater than a preset value, the valve assembly disconnects the two hot water channels and forms two first circulating water channels respectively. The two circulating water pumps drive the water in the two first circulating water channels to circulate. When the temperature inside the second mounting cavity is less than or equal to the preset value, the valve assembly connects the two hot water channels to form a second circulating water channel, and at least one circulating water pump drives the water in the second circulating water channel to circulate.

[0016] The method of using the fast charging terminal according to the embodiments of this application has at least the following beneficial effects: When the weather is hot, it can effectively reduce the heat generated by the charging module from being transferred to the control module and communication module. When the temperature is low, it can transfer the heat generated by the charging module to the control module and communication module, thus preventing the control module and communication module from being too hot or too cold, which could affect their performance or even cause damage.

[0024] The following is for reference. Figures 1 to 3 This application describes a fast-charging terminal and its usage method according to embodiments of the present application.

[0025] refer to Figures 1 to 3 As shown, a fast charging terminal according to a first aspect embodiment of this application includes a housing 100 and a heat-conducting component 200.

[0026] For example, a fast-charging terminal may also include a charging pile, a charging module 300, a communication module 400, a control module 500, and a charging gun. The housing 100 is located on the charging pile, and the charging module 300, communication module 400, and control module 500 are located inside the housing 100. The charging gun is located in the housing 100. The charging module 300 charges the battery of the electric two-wheeler through the charging gun. The communication module 400 is used to enable the fast-charging terminal to exchange information with other devices, networks, or the cloud via wired or wireless means. The control module 500 is used to control the operation of the fast-charging terminal. The communication module 400 and the control module 500 are common components of fast-charging terminals, and their structure and working principle will not be described in detail here.

[0027] The housing 100 has two partitions 101 inside, dividing the interior of the housing 100 into a first mounting cavity 102, a heat dissipation cavity 103, and a second mounting cavity 104 arranged sequentially. For example, the two partitions 101 can be arranged horizontally and extend vertically, so that the first mounting cavity 102, the heat dissipation cavity 103, and the second mounting cavity 104 can be arranged sequentially from top to bottom, with the heat dissipation cavity 103 located between the first mounting cavity 102 and the second mounting cavity 104. The first mounting cavity 102 is used to mount the charging module 300, and the second mounting cavity 104 can be used to mount the communication module 400, the control module 500, and most other components.

[0028] The heat-conducting assembly 200 includes two heat-conducting plates 201 and a valve assembly 202. The two heat-conducting plates 201 are respectively disposed in the first mounting cavity 102 and the second mounting cavity 104, and both extend into the heat dissipation cavity 103. The heat-conducting plates 201 are provided with heat-conducting channels 203. The heat-conducting channels 203 at the first mounting cavity 102 extend into both the first mounting cavity 102 and the heat dissipation cavity 103, and the heat-conducting channels 203 at the second mounting cavity 104 extend into both the second mounting cavity 104 and the heat dissipation cavity 103. The heat-conducting channels 203 are equipped with a circulating water pump 204. The valve assembly 202... 2. Located between two hot water conduction plates 201, wherein when the temperature in the second mounting cavity 104 is greater than a preset value, the valve assembly 202 disconnects the two hot water conduction channels 203 and forms two first circulating water channels respectively, and the two circulating water pumps 204 drive the water in the two first circulating water channels to circulate; when the temperature in the second mounting cavity 104 is less than or equal to the preset value, the valve assembly 202 connects the two hot water conduction channels 203 to form a second circulating water channel, and at least one circulating water pump 204 drives the water in the second circulating water channel to circulate.

[0029] In this application, the heat dissipation cavity 103 is located between the first mounting cavity 102 and the second mounting cavity 104. The charging module 300 is installed in the first mounting cavity 102, and the communication module 400 and the control module 500 can be installed in the second mounting cavity 104. They are separated by the heat dissipation cavity 103, which can reduce the direct heat transfer between the first mounting cavity 102 and the second mounting cavity 104.

[0030] When the weather is hot, and the temperature inside the second mounting cavity 104 exceeds the preset value, the valve assembly 202 disconnects the two hot water channels 203 and forms two separate first circulating water channels. The two circulating water pumps 204 drive the water in the two first circulating water channels to circulate. When the water in the first circulating water channel at the first mounting cavity 102 circulates, it can transfer the heat generated by the charging module 300 to the heat dissipation cavity 103 for dissipation. When the water in the first circulating water channel at the second mounting cavity 104 circulates, it can transfer the heat generated by the multiple components in the second mounting cavity 104 to the heat dissipation cavity 103 for dissipation, thereby achieving heat dissipation for each component.

[0031] Furthermore, the two hot water channels 203 are disconnected, which effectively reduces the heat generated by the charging module 300 from being transferred to the control module 500, communication module 400, or other components in the second mounting cavity 104, thus preventing the communication module 400, control module 500, or other components from overheating and affecting their performance or causing damage.

[0032] When the weather is cold, when the temperature inside the second mounting cavity 104 is less than or equal to a preset value, the valve assembly 202 connects the two hot water conduction channels 203 to form a second circulating water channel. The second circulating water channel passes through the first mounting cavity 102, the second mounting cavity 104, and the heat dissipation cavity 103, so that the heat generated by the charging module 300 can be transferred to the first mounting cavity 102. In this way, the heat energy can be effectively used to heat the control module 500, the communication module 400, or other components, so as to avoid the communication module 400, the control module 500, or other components being too cold, affecting their performance or causing damage. It can also prevent condensation or frost from causing short circuits and damage.

[0033] Furthermore, the first mounting cavity 102 and the second mounting cavity 104 of this application dissipate heat directly through two hot water conduction plates 201. Compared with the side walls of the first mounting cavity 102 and the second mounting cavity 104 being equipped with fans for heat dissipation, this can reduce the amount of rainwater and dust entering the first mounting cavity 102 and the second mounting cavity 104.

[0034] refer to Figures 1 to 3As shown, in some embodiments of this application, the valve assembly 202 includes a docking plate 205 and four directional valves 208. The docking plate 205 has two oppositely arranged first channels 206 and two oppositely arranged second channels 207. The two first channels 206 and the two second channels 207 form a quadrilateral structure. The four directional valves 208 are respectively located at the four corners of the quadrilateral structure. The directional valves 208 are connected to adjacent first channels 206 and second channels 207. The two ends of the hot water conduction channel 203 are respectively formed as connection ends. The four directional valves 208 are respectively connected to the four connection ends, and the two connection ends of the same hot water conduction channel 203 are respectively connected to two adjacent directional valves 208.

[0035] For example, when the first mounting cavity 102, the heat dissipation cavity 103, and the second mounting cavity 104 are arranged sequentially from top to bottom, the two first channels 206 can be arranged vertically and extend in the left-right direction, the two second channels 207 can be arranged horizontally and extend in the up-down direction, the two connecting ends of the upper hot water channel 203 can be located on the left and right sides of the bottom end of the upper hot water plate 201 respectively, and the two reversing valves 208 can be located on the left and right sides of the bottom end of the upper hot water plate 201 respectively, the two connecting ends of the lower hot water channel 203 can be located on the left and right sides of the top end of the lower hot water plate 201 respectively, and the other two reversing valves 208 can be located on the left and right sides of the top end of the lower hot water plate 201 respectively, and the other two reversing valves 208 can be located on the left and right sides of the top end of the lower hot water plate 201 respectively. Each reversing valve 208 is connected to its adjacent connecting end, the corresponding end of the first channel 206, and the corresponding end of the second channel 207.

[0036] In this embodiment, when the temperature inside the second mounting cavity 104 is greater than a preset value, multiple reversing valves 208 cooperate to disconnect the two hot water conduction channels 203 from the second channel 207, and connect the two ends of the upper hot water conduction channel 203 to the two ends of the upper first channel 206, and connect the two ends of the lower hot water conduction channel 203 to the two ends of the lower first channel 206, thus forming two separate first circulating water channels connected end to end. When the temperature inside the second mounting cavity 104 is less than the preset value, multiple reversing valves 208 cooperate to disconnect the two hot water conduction channels 203 from the first channel 206, and connect the left ends of the two hot water conduction channels 203 to the two ends of the left second channel 207, and connect the right ends of the two hot water conduction channels 203 to the two ends of the right second channel 207, thus connecting the two hot water conduction channels 203 to form a second circulating water channel connected end to end, making switching simple and convenient.

[0037] In some embodiments of this application, the mating plate 205 is made of a thermal insulation material. For example, it can be made of extruded polystyrene board and expanded polystyrene board.

[0038] Thus, when the weather is hot and the temperature inside the second mounting cavity 104 exceeds the preset value, the two hot water conduction plates 201 can be prevented from transferring heat through the docking plate 205, thereby further reducing the heat generated by the charging module 300 from being transferred to the control module 500, communication module 400, or other components in the second mounting cavity 104.

[0039] refer to Figure 1 As shown, in some embodiments of this application, a heat dissipation plate is attached to the surface of one end of the two hot water conducting plates 201 located inside the heat dissipation cavity 103, and the heat dissipation plate is provided with a plurality of heat dissipation fins 209. In this way, when the heat in the first mounting cavity 102 and the second mounting cavity 104 is transferred to the heat dissipation cavity 103, the heat dissipation effect is better.

[0040] refer to Figure 1 As shown, in some embodiments of this application, air vents and cooling fans 105 are respectively provided on opposite sides of the heat dissipation cavity 103. For example, the cooling fan 105 can be used to draw air from the heat dissipation cavity 103, and the air vent can be an air inlet. Of course, the cooling fan 105 can also be used to blow air into the heat dissipation cavity 103, and the air vent can be an air outlet.

[0041] In this embodiment, an air vent and a cooling fan 105 are provided to improve the heat dissipation effect of the heat dissipation cavity 103.

[0042] refer to Figure 1 As shown, in some embodiments of this application, the cooling fan 105 is used to draw air from the cooling cavity 103, a filter plate is provided on the outside of the air vent, and a detachable anti-theft mesh plate 106 is provided on the inside of the air vent. For example, the anti-theft mesh plate 106 can be installed on the inside of the air vent by fasteners or snapped onto the inside of the air vent, that is, it is detachably provided inside the housing 100.

[0043] In this embodiment, the cooling fan 105 is used to draw air from the heat dissipation cavity 103. The air outlet is an air inlet, and a filter plate is provided on the outside of the air outlet to reduce dust entering the heat dissipation cavity 103. In addition, the anti-theft mesh panel 106 is detachably installed inside the enclosure 100. The anti-theft mesh panel 106 can only be opened by opening the door of the enclosure 100, and cannot be opened from the outside, thus improving the anti-theft effect.

[0044] refer to Figure 1 As shown, in some embodiments of this application, the arrangement direction of the plurality of heat sinks 209 on the heat sink plate is perpendicular to the arrangement direction of the air vent and the cooling fan 105. In this way, the airflow generated by the cooling fan 105 can pass through the gap between two adjacent heat sinks 209, avoiding the heat sinks 209 from obstructing the airflow, thereby improving the heat dissipation effect.

[0045] refer to Figure 1As shown, in some embodiments of this application, a temperature sensor 107 is provided in the second mounting cavity 104. The temperature sensor 107 is used to detect the temperature in the second mounting cavity 104. The temperature sensor 107 and the valve assembly 202 are adapted to be connected to the control module 500. The control module 500 controls the operation of the valve assembly 202 and the circulating water pump 204 according to the detection result of the temperature sensor 107.

[0046] In this embodiment, a temperature sensor 107 is provided. The temperature sensor 107 can detect the temperature inside the second mounting cavity 104. When the detected temperature inside the second mounting cavity 104 is greater than a preset value, the control module 500 controls the valve assembly 202 to disconnect the two hot water conduction channels 203 and form two first circulating water channels respectively. The control module 500 also controls two circulating water pumps 204 to drive the water in the two first circulating water channels to circulate. When the detected temperature inside the second mounting cavity 104 is less than the preset value, the control module 500 controls the valve assembly 202 to connect the two hot water conduction channels 203 to form a second circulating water channel. The control module 500 also controls at least one circulating water pump 204 to drive the water in the second circulating water channel to circulate. This results in a higher degree of automation and greater ease of use.

[0047] In some embodiments of this application, the hot water conduction plate 201 in the first mounting cavity 102 is configured to be in contact with the charging module 300. This allows the heat generated by the charging module 300 to be better transferred to the hot water conduction plate 201, and then transferred by the hot water conduction plate 201 to the heat dissipation cavity 103 or the second mounting cavity 104, resulting in better heat dissipation.

[0048] The fast charging terminal usage method according to the second aspect of the present application, and the fast charging terminal based on the first aspect of the present application, includes, but is not limited to, the following steps: Detect the temperature inside the second mounting cavity 104; When the temperature inside the second mounting cavity 104 is greater than the preset value, the valve assembly 202 disconnects the two hot water channels 203 and forms two first circulating water channels respectively. The two circulating water pumps 204 drive the water in the two first circulating water channels to circulate. When the temperature in the second mounting cavity 104 is less than or equal to a preset value, the valve assembly 202 connects the two hot water channels 203 to form a second circulating water channel, and at least one circulating water pump 204 drives the water in the second circulating water channel to circulate.

[0049] In this embodiment, when the weather is hot, the heat generated by the charging module 300 can be effectively reduced to be transferred to the control module 500 and the communication module 400. When the temperature is too low, the heat generated by the charging module 300 can be transferred to the control module 500 and the communication module 400, thus preventing the control module 500 and the communication module 400 from being too hot or too cold, which would affect their performance or cause damage.

[0050] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
