Description

Technical Field

[0001] This invention relates to the field of JP cabinet technology, specifically a dual-power JP cabinet with humidity regulation function. Background Technology

[0002] Dual-power JP cabinets are outdoor integrated power distribution equipment that integrates power distribution, metering, protection, control, and reactive power compensation. They are equipped with key electrical components such as dual-power automatic transfer switches, circuit breakers, and controllers, and are widely used in important places requiring uninterrupted power supply, such as high-rise buildings, industrial and mining enterprises, and telecommunications.

[0003] Since JP cabinets operate outdoors for extended periods, the humidity and temperature control within the cabinet directly impacts the safe operation and lifespan of the electrical equipment. Existing technologies have proposed various solutions for dehumidification and heat dissipation in dual-power cabinets or JP cabinets. For example, application number "CN202223379699.6" describes a dual-power cabinet that uses a rectangular frame and dehumidifying bags at the heat dissipation vents to dry the air entering the cabinet. Another application number, "CN201920501155.1" describes a dual-power supply ring network cabinet that uses temperature and humidity sensors in conjunction with an evaporator, condenser, and PLC controller to achieve automatic heat dissipation and dehumidification. Furthermore, some intelligent JP cabinets with dehumidification and heat dissipation functions combine a refrigeration system consisting of a compressor, evaporator, and condenser with desiccant adsorption to treat internal moisture.

[0004] However, the aforementioned existing technologies still have the following shortcomings in practical applications: First, dehumidification and heat dissipation functions are mostly designed independently or simply superimposed. The heat generated by condensation dehumidification is usually directly discharged into the environment without being effectively utilized, resulting in energy waste and a low system energy efficiency ratio. Second, desiccant adsorption schemes are mostly single-path airflow treatments. Once the desiccant is saturated, it needs to be shut down for replacement or regeneration, making continuous and uninterrupted dehumidification impossible. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dual-power JP cabinet with humidity regulation function, which solves the problem that existing independent or simply superimposed dehumidification and heat dissipation designs cannot achieve continuous, efficient, and adaptive internal environment management within the cabinet.

The refrigeration unit has its cold end thermally coupled to the side wall of the second airflow channel for cooling the gas passing through the second airflow channel; its hot end is thermally coupled to the desiccant block located at the port of the first airflow channel for heating and regenerating the desiccant block.

[0007] Preferably, the air intake module includes: The first channel component has one end fixedly connected to the side wall of the cabinet, and the port of the first channel component corresponds to the through hole; A fan component is fixed in the middle of the first channel component, such that the side of the fan component and the inner side of the first channel component form an extended area. A guide plate inclined toward the fan component is fixedly connected to the inner side of the extended area. A first inlet corresponding to the guide plate is opened on the side of the fan component.

[0008] Preferably, the first channel component has a port away from the cabinet and a number of spaced leaf plates fixedly connected to the corresponding area on the outside of the guide plate.

[0009] Preferably, the flow divider housing has a set of parallel and opposite mounting sides, one of which has a plurality of second airflow channels fixedly connected at intervals, and a fin is provided on the mounting side in a first region between two adjacent second airflow channels; the other mounting side has a plurality of first airflow channels fixedly connected at intervals, one end of which extends into the interior of the flow divider housing and corresponds to the fin.

[0010] Preferably, it further includes: an exhaust channel, the exhaust channel being fixedly connected to the cabinet body, and the opening of the exhaust channel facing the outside of the cabinet body, and one end of the first airflow channel being fixedly connected to the exhaust channel.

[0011] Preferably, the second airflow channel includes: a main body shell, which is inclined upward and the cross-sectional area of ​​the main body shell gradually decreases along the direction away from the diversion shell; The main body shell has several air outlets on its side, and each air outlet is connected to a corresponding anti-reverse baffle.

[0012] Preferably, the movable desiccant module includes: A regenerable desiccant module is vertically slidably arranged along the inner sidewall of the diversion shell. The regenerable desiccant module includes a desiccant storage frame and desiccant blocks installed on the desiccant storage frame, with the first desiccant block and the second desiccant block being staggered. The lifting component is fixedly connected to the inner wall of the diversion shell, and the top telescopic end of the lifting component is fixedly connected to the desiccant storage frame.

[0013] Preferably, the refrigeration unit includes: A cooling element is fixedly connected to the lower side wall of the main body shell, with the cold end of the cooling element facing the lower side wall of the main body shell. A heat insulation cover is fixedly connected to the first area of ​​the main shell and the flow distribution shell, at least covering the first area of ​​the cooling chip and the flow distribution shell to form a sealed area.

[0014] Preferably, the cooling element is a semiconductor cooling device.

[0015] Preferably, a drain pipe is fixedly connected to one side of the diversion shell near the bottom.

[0016] This invention provides a dual-power JP cabinet with humidity regulation function. It has the following beneficial effects: This invention introduces airflow by setting an air intake module located on the outside of the cabinet and an air guide component located on the inside of the cabinet. The air guide component is designed with a collaborative system consisting of a refrigeration unit, a first airflow channel, a second airflow channel, and a switchable desiccant module, thus constructing a system that integrates drying gas, heat dissipation and cooling, and desiccant recovery. Specifically, when outside air is introduced through the air intake assembly, it passes through the desiccant block and the second airflow channel. Initial drying of the gas occurs at the desiccant block. The sidewall of the second airflow channel is thermally coupled to the cold end of the refrigeration unit. As the gas flows through, it is cooled, causing water in the gas to precipitate and adhere to the channel wall for condensation and dehumidification. Simultaneously, the cooled, dried gas, with its lower temperature, can be directly used for heat dissipation and cooling of electrical components inside the cabinet, achieving "dual cooling"—both dehumidification and cooling. At the same time, the heat generated at the hot end of the refrigeration unit is conducted to the desiccant block currently corresponding to the port of the second airflow channel, regenerating it by heating and decomposing the water adsorbed in the previous working cycle. The hot, humid exhaust gas is then discharged outside the cabinet through the first airflow channel, achieving in-situ desiccant recovery. After the desiccant module has been used for a period of time, its position is switched. The recovered desiccant block enters the port of the second airflow channel to begin a new round of adsorption and dehumidification, while the other desiccant block enters the regeneration state. This design uses the refrigeration unit simultaneously as a dehumidification cold source, a heat dissipation cold source, and a regeneration heat source, forming a synergistic cycle of "dehumidification-heat dissipation-regeneration": the cooling generated at the cold end serves both gas drying and cabinet heat dissipation, while the heat generated at the hot end is used for desiccant replenishment, allowing the same electrical energy to be converted into three functions simultaneously: dehumidification, heat dissipation, and regeneration. Compared to existing technologies where the dehumidification system, heat dissipation system, and desiccant replacement or external heating regeneration system are independent and consume their own energy, the integrated system of this invention achieves tiered energy utilization and organic integration of functions, significantly improving energy efficiency; the desiccant is replenished in situ within the cabinet without disassembly or replacement, reducing maintenance costs; the cooled dry gas is directly used for heat dissipation, avoiding the additional energy consumption and space occupation caused by setting up a separate cooling fan, and improving heat dissipation efficiency by utilizing the low gas temperature; the entire system simultaneously completes the three tasks of dry gas production, cabinet cooling, and desiccant replenishment within the same working cycle, with a compact structure, high operating efficiency, and optimized energy consumption, making it particularly suitable for outdoor dual-power JP cabinet applications with high requirements for reliability, continuity, and energy efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] like Figures 1-8 As shown, this embodiment of the invention provides a dual-power JP cabinet with humidity regulation function, which is suitable for continuous, long-term uninterrupted operation systems. Specifically, it includes: cabinet body 1, air inlet component 2, and air outlet component 3. The cabinet body 1 has a cubic structure, with the air inlet component 2 fixedly installed on its left side and the air outlet component 3 arranged on its right side, which is parallel to and opposite to the left side.

[0021] It is understandable that air is introduced into the cabinet 1 from the air intake component 2 to dissipate heat from the circuits and electronic components inside the cabinet 1. The hot air is then discharged outside the cabinet through the air outlet component 3, thus achieving heat dissipation for the circuits and electronic components inside the cabinet 1. Inside the cabinet 1, there can also be flow channels or flow guide plates designed to guide airflow and dissipate heat from important circuits and electronic components according to a preset path.

[0022] A preferred implementation is that the air outlet assembly 3 is located on the right side of the cabinet 1 near the top, so that the gas carrying heat can be easily discharged from the location of the air outlet assembly 3.

[0023] Specifically, the air intake assembly 2 includes an air intake module 201 located on the outside of the cabinet 1 and an air guide assembly 202 located on the inside of the cabinet 1. The air intake module 201 and the air guide assembly 202 are connected through a through hole opened on the side wall of the cabinet 1. The air intake module 201 provides power to transport the air outside the cabinet 1 through the through hole to the air guide assembly 202. After the airflow is processed by the air guide assembly 202, it enters the interior of the cabinet 1 to dissipate heat from the circuits and electronic devices inside the cabinet 1.

[0024] In order to achieve more efficient heat dissipation and reduce the humidity inside the cabinet 1, and to ensure the dryness of the air entering the cabinet 1, the air guide assembly 202 is designed as follows.

[0025] The air guide assembly 202 includes: a flow divider housing 2021, a first airflow channel 2025, several second airflow channels 2027, a movable desiccant module, and a refrigeration unit.

[0026] The distribution housing 2021 has an air inlet communicating with a through hole. Air introduced from the outside (referring to the outside of cabinet 1, hereinafter the same terminology) by the air intake module 201 enters the interior of the distribution housing 2021 after passing through the through hole. The first airflow channel 2025 and the second airflow channel 2027 are both located on the distribution housing 2021 and communicate with its interior. The first airflow channel 2025 guides the gas inside the distribution housing 2021 to the outside of cabinet 1; this gas is used to assist in the heating and regeneration of the desiccant block. The second airflow channel 2027 guides the gas inside the distribution housing 2021 to the interior of cabinet 1; this gas is used to dissipate heat from the circuits and electronic components inside cabinet 1. A movable desiccant is also present. The module is equipped with desiccant blocks, including a first desiccant block 20242 and a second desiccant block 20243. The desiccant module can switch between a first position and a second position. When the desiccant module is in the first position, the first desiccant block 20242 corresponds to the port of the first airflow channel 2025, and the second desiccant block 20243 corresponds to the port of the second airflow channel 2027. In this position, part of the gas inside the diversion housing 2021 is preliminarily dried by the second desiccant block 20243 and then enters the second airflow channel 2027. After passing through the second airflow channel 2027, it dissipates heat from the circuits and electronic components inside the cabinet 1. The other part of the gas passes through the first desiccant block 20242... The first airflow channel 2025 discharges to the outside. When the desiccant module is in the second position, the first desiccant block 20242 corresponds to the port of the second airflow channel 2027, and the second desiccant block 20243 corresponds to the port of the first airflow channel 2025. In this position, part of the gas inside the diversion housing 2021 is initially dried by the first desiccant block 20242 and then enters the second airflow channel 2027. After passing through the second airflow channel 2027, it dissipates heat from the circuits and electronic components inside the cabinet 1. The other part of the gas is discharged to the outside after passing through the second desiccant block 20243 and the first airflow channel 2025. The cold end of the refrigeration unit is thermally coupled to the side wall of the second airflow channel 2027 to dissipate heat from the gas passing through the second airflow channel 2027. The gas in the second airflow channel 2027 is cooled down, thus the gas passing through the second airflow channel 2027 is condensed, further reducing the moisture content in the air, and cooling this part of the gas improves the subsequent heat dissipation effect; the hot end of the refrigeration unit is thermally coupled to the desiccant block located at the port of the first airflow channel 2025, which is used to heat and regenerate the desiccant block. Thus, some gas passes through the desiccant block (first desiccant block 20242 or second desiccant block 20243) corresponding to the first airflow channel 2025. Since the desiccant block at this location is heated, the gas can carry away some of the moisture in the desiccant block when passing through it, and then it is discharged to the outside after passing through the first airflow channel 2025.

[0027] It is understandable that when the movable desiccant module switches positions, it can manipulate the first desiccant block 20242 or the second desiccant block 20243 to correspond with the first airflow channel 2025 and the hot end of the refrigeration unit, thereby achieving heating and regeneration of the corresponding desiccant block. This allows one of the first desiccant block 20242 and the second desiccant block 20243 to be in a drying state, while the other is in a heating and regeneration state. After a period of use, the movable desiccant module switches positions, thus exchanging the positions of the desiccant blocks in the drying and heating and regeneration states. This enables continuous and long-term stable operation without the need for manual replacement of desiccant blocks, and works well with the dual power supply JP cabinet (one main and one backup for safety).

[0028] Understandably, the cold end of the refrigeration unit is thermally coupled to the side wall of the second airflow channel 2027 to cool the gas passing through the second airflow channel 2027, and the gas passing through the second airflow channel 2027 is condensed to further reduce the moisture content in the air; the hot end of the refrigeration unit is used to heat and regenerate the desiccant block. This combination structure design allows both the cold and hot ends of the refrigeration unit to be fully utilized, resulting in optimal energy utilization.

[0029] In one embodiment, the air intake module 201 includes: a first channel component 2011, a fan component 2014, and a guide plate 2012.

[0030] like Figure 4 As shown, one end of the first channel component 2011 is fixedly connected to the side wall of the cabinet 1, the port of the first channel component 2011 corresponds to the through hole, the fan component 2014 is fixed in the middle of the first channel component 2011, so that the side of the fan component 2014 and the inner side of the first channel component 2011 form an extended area, and a guide plate 2012 inclined towards the fan component 2014 is fixedly connected to the inner side of the extended area, and a first inlet a1 corresponding to the guide plate 2012 is opened on the side of the fan component 2014.

[0031] Understandably, a typical fan component 2014 has a second inlet a2 located at its end. When the fan component 2014 is working, it can transport outside air to the outlet end of the fan component 2014, thereby entering the interior of the splitter housing 2021. Some of the outside air will be guided by the guide plate 2012, flowing along the side wall of the guide plate 2012, entering the fan component 2014 through the first inlet a1, and then being transported to the interior of the splitter housing 2021. This part of the air flowing along the side wall of the guide plate 2012 can achieve preliminary condensation. Especially in rainy weather, the second inlet a2 of the fan component 2014 can be blocked, and most of the air will flow along the side wall of the guide plate 2012, enter the fan component 2014 through the first inlet a1, and then be transported to the interior of the splitter housing 2021, preventing rainwater-laden air with a high moisture content from entering the interior of the splitter housing 2021.

[0032] In one embodiment, the first channel component 2011 has a port away from the cabinet 1 and is fixedly connected to a number of spaced leaf components 2013 in the corresponding area on the outside of the guide plate 2012.

[0033] Several spaced blades 2013 form the first barrier net, reducing the direct entry of rainwater into the extended area.

[0034] In one embodiment, the flow divider housing 2021 has a set of parallel and opposite mounting sides. A plurality of second airflow channels 2027 are fixedly connected at intervals on one of the mounting sides. A fin 2029 is provided on a first region b located between two adjacent second airflow channels 2027 on the mounting side. The fin 2029 is used to conduct heat from the hot end of the refrigeration unit and to improve the thermal coupling to the desiccant block. A plurality of first airflow channels 2025 are fixedly connected at intervals on the other mounting side. One end of the first airflow channel 2025 extends into the interior of the flow divider housing 2021 and corresponds to the fin 2029, ensuring that the desiccant block corresponding to the first airflow channel 2025 can contact the fin 2029.

[0035] It is understood that the hot end of the refrigeration unit heats the finned element 2029, and the finned element 2029 heats the desiccant block located there. The gas passes through the heated desiccant block, and then passes through the first airflow channel 2025 before being discharged to the outside.

[0036] In one embodiment, it further includes: an exhaust channel 2026, which is fixedly connected to the cabinet 1 and the opening of the exhaust channel 2026 faces the outside of the cabinet 1, and one end of the first airflow channel 2025 is fixedly connected to the exhaust channel 2026.

[0037] The exhaust trough 2026 has an elongated structure and is connected to multiple first airflow channels 2025 to ensure the structural stability of the multiple first airflow channels 2025. The gas discharged through the first airflow channels 2025 first enters the exhaust trough 2026, and then the exhaust trough 2026 discharges to the outside.

[0038] In one embodiment, the second airflow channel 2027 includes: a main shell 20271, which is inclined upward to facilitate gas flow. Along the direction away from the diversion shell 2021, the cross-sectional area of ​​the main shell 20271 gradually decreases. When the gas flows from the direction of large cross-section to small cross-section, a region with greater air pressure is formed at the end of the main shell 20271. Several air outlets 20272 are opened on the side of the main shell 20271. Each air outlet 20272 is connected to a corresponding anti-reverse baffle 20273. In the region with greater air pressure formed at the end of the main shell 20271, this part of the gas can push open the anti-reverse baffle 20273, so that the gas inside the main shell 20271 can smoothly enter the interior of the cabinet 1.

[0039] Specifically, the anti-reverse baffle 20273 includes a lightweight plastic sheet. One side of the lightweight plastic sheet is bonded to the side wall of the air outlet 20272 of the main body shell 20271. Then, a counterweight plate is fixedly connected to the center of the lightweight plastic sheet, so that the anti-reverse baffle 20273 can block the air outlet 20272 in its natural state. Furthermore, a region with a large air pressure is formed at the end of the main body shell 20271, which allows the gas inside the main body shell 20271 to smoothly enter the interior of the cabinet 1.

[0040] Of course, when the airflow inside the main body shell 20271 is relatively large, the air pressure in each area inside the main body shell 20271 is relatively large, and all the check valves 20273 can be opened.

[0041] In one embodiment, the movable desiccant module includes a regenerable desiccant module 2024 and a lifting member 2023 that are vertically disposed along the inner sidewall of the diversion shell 2021.

[0042] The lifting component 2023 is fixedly connected to the inner wall of the diversion shell 2021, and the top telescopic end of the lifting component 2023 is fixedly connected to the desiccant storage frame 20241. The lifting component 2023 is used to drive the regenerable desiccant module 2024 to move up and down; for example, driving the regenerable desiccant module 2024 to the top, so that it is in the first position, and driving the regenerable desiccant module 2024 to the bottom, so that it is in the second position.

[0043] Specifically, the renewable desiccant module 2024 includes a desiccant storage frame 20241 and desiccant blocks installed on the desiccant storage frame 20241, with the first desiccant block 20242 and the second desiccant block 20243 being distributed alternately.

[0044] like Figure 5 As shown, the first desiccant block 20242 and the second desiccant block 20243 are positioned using a storage frame 20241, so that the gas inside the diversion shell 2021 can enter the first desiccant block 20242 and the second desiccant block 20243 from all directions, and rely on the first airflow channel and the second airflow channel to guide the airflow.

[0045] In one embodiment, the cooling unit includes a cooling chip 20210, a heat insulation cover 2028, and a heat-conducting component.

[0046] The cooling element 20210 is fixedly connected to the lower side wall of the main body shell 20271, with the cold end of the cooling element 20210 facing the lower side wall of the main body shell 20271. The cooling element 20210 is used to cool the lower side wall of the main body shell 20271, so that the gas passing through the main body shell 20271 can be cooled. The heat insulation cover 2028 is fixedly connected to the first region b of the main body shell 20271 and the diversion shell 2021, covering at least the cooling element 20210 and the first region b of the diversion shell 2021 inside to form a sealed area. The hot end of the cooling element 20210 faces the sealed area. The sealed area is filled with a heat-conducting element, which can be a fluid or a solid, to transfer the heat from the hot end of the cooling element 20210 to the first region b to heat the finned element 2029. For example, the heat-conducting element can be made of silicone, and the heat insulation cover 2028 is a multi-layer composite heat insulation material.

[0047] In one embodiment, the cooling chip 20210 is a semiconductor cooling device. Semiconductor cooling devices have a simple structure, are easy to arrange, and can achieve cooling and heating simply by being powered on.

[0048] In one embodiment, a drain pipe 2022 is fixedly connected to one side of the diversion housing 2021 near the bottom end for draining water from inside the diversion housing 2021.

[0049] It is understandable that setting the main body shell 20271 at an upward angle also facilitates the flow of condensate from the inner wall of the main body shell 20271 into the interior of the diversion shell 2021 and out through the drain pipe 2022.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
