[0001] This invention relates to the field of rail transit air conditioning technology, specifically a novel integrated air conditioning device for rail transit. Background Technology

[0002] The air conditioning system in rail transit (such as subways, high-speed trains, and bullet trains) is a key system to ensure passenger comfort. It is mainly used to regulate the temperature, humidity, air flow rate and air quality in the carriage. At the same time, it needs to adapt to special environments such as high-speed operation, vibration and space constraints. It mainly consists of air outlets, air inlets and air conditioning units. In addition, the top of the rail transit carriage is equipped with a power supply module.

[0003] However, existing air conditioning systems for rail transit have several drawbacks. When the air conditioning system is heating, it is not convenient to reuse the heat generated by the power supply module, resulting in heat waste and making it neither energy-efficient nor environmentally friendly. Furthermore, when the air conditioning system is cooling, it is not convenient to pre-cool the hot air in the carriage, making it neither energy-efficient nor environmentally friendly. Summary of the Invention

At least one set of condensers is installed in the receiving box, and the air conditioning unit is installed in the receiving box and arranged adjacent to the condensers. The bottom of the air conditioning unit is provided with heat dissipation fins.

[0006] Ideally, the protective cover has an air duct that matches the air outlet and air inlet, and an adjustable air duct baffle can be installed inside the air duct.

[0009] Ideally, the protective cover has at least two air inlets on its side, and the air inlets are connected to each receiving chamber through a first flow channel; the two end faces of the protective cover each have an air outlet, and the air outlet is connected to each receiving chamber through a second flow channel, and the air duct includes the first flow channel and the second flow channel.

[0010] Ideally, the housing is divided into multiple housing chambers by baffles, and the air conditioning unit is installed in the middle housing chamber.

[0011] Ideally, the condenser is also installed in the central receiving chamber on both sides of the air conditioning unit.

[0012] Ideally, the protective cover has at least two air inlets on its side, and the air inlets are connected to the middle receiving chamber through a first flow channel; the two end faces of the protective cover each have an air outlet, and the air outlet is connected to the middle receiving chamber through a second flow channel. The air duct includes the first flow channel and the second flow channel.

[0013] Another objective of this invention is to provide a novel integrated air conditioning device for rail transit, comprising a protective cover installed on the top of the carriage, wherein a power supply module, a waste discharge module, an auxiliary reversing module, and an air conditioning module are disposed within the protective cover. The air conditioning module includes an air outlet, an air inlet, and an air conditioning unit. The air conditioning unit includes an air inlet pipe and an air outlet pipe. A first connecting pipe is fixedly connected between the air outlet and the air outlet pipe. A second connecting pipe is fixedly connected to the top of the air inlet. A heat exchange box is fixedly inserted into the side wall of the second connecting pipe, and the heat exchange box is fixedly inserted into the side wall of the air inlet pipe. An air inlet pipe is fixedly connected to the side wall of the power supply module, and an exhaust pipe is fixedly connected to the bottom of the power supply module. A fan is installed on the side wall of the exhaust pipe, and the other end of the exhaust pipe is fixedly connected to...

Simultaneously, it enables the application of cooling water and airflow through the heat exchange pipes to pre-cool the air entering the air conditioning unit, resulting in greater energy efficiency and environmental friendliness.

Detailed Implementation

[0016] 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 1

[0017] like Figures 1 to 3 The novel integrated air conditioning device for rail transit shown includes a protective cover 1202' installed on the top of the car 1. The protective cover 1202' houses a power supply module, a waste discharge module, an auxiliary reversing module, and an air conditioning module. By centrally arranging these modules (or equipment, such as the power supply module, waste discharge module, auxiliary reversing module, and air conditioning module) within the protective cover 1202', eliminating their original placement at the bottom of the car or other locations, it helps reduce the overall weight of the vehicle and saves space.

[0018] The protective cover 1202' has an air outlet and an air inlet. An air duct is formed inside the protective cover 1202' to cooperate with the air outlet and air inlet. An adjustable air duct baffle can be installed inside the air duct (the adjustable method can use existing conventional methods, allowing the air duct baffle to be adjusted to close or open the air duct; that is, the air duct baffle can be installed or not). The air conditioning module includes at least an air conditioning unit 1204', the specific structure of which can be referred to existing conventional structures.

[0019] The protective cover 1202' includes a support frame 1200' installed on the top of the carriage 1, a limiting and receiving frame 1201' installed at the bottom of the support frame 1200' and spaced apart to be embedded in the carriage 1 (the protective cover 1202' can be firmly supported and embedded in the top of the carriage 1 by the support frame 1200' and the limiting and receiving frame 1201', the support frame 1200' is connected to the top of the carriage 1 by fasteners and sealed with sealing rings, sealant, etc., and the end face of the limiting and receiving frame 1201' has the aforementioned air outlet), and a receiving box 1203' formed on the support frame 1200' (formed by welding or integral molding, the receiving box 1203' is used to install the aforementioned power supply module, waste discharge module, auxiliary inverter module and air conditioning module, etc.). In this embodiment, the receiving box 1203' is divided into multiple receiving chambers by baffles, and the air conditioning unit 1204' is installed in any one of the receiving chambers, such as Figure 3 As shown, the air conditioning unit 1204' is installed in the central receiving chamber, and the bottom of the air conditioning unit 1204' is provided with multiple heat dissipation fins arranged at equal intervals; this novel integrated air conditioning device for rail transit also has at least one set of condensers 11' (two sets in this embodiment, also referred to as condensing units), which are also installed in the central receiving chamber and located on both sides of the power supply module, waste discharge module, and auxiliary inverter module, etc. In addition, an evaporation unit is installed in each of the two receiving chambers adjacent to the central receiving chamber.

[0020] It should be noted that the multiple containment chambers are not isolated from each other; they are interconnected through a ventilation structure. Specifically, the protective cover 1202' has at least two air inlets 1205' on its side (the air inlets 1205' usually correspond to the evaporator unit). The two air inlets 1205' are respectively connected to the middle receiving chamber through a first flow channel (the first flow channel is more preferably connected to each receiving chamber, and a valve can be installed at the connection point for opening and closing control). The two end faces of the protective cover 1202' each have an air outlet 1206' (the air outlet 1206' is opened on the limiting receiving frame 1201'), so that the air outlet 1206' is connected to the middle receiving chamber through a second flow channel (the second flow channel is more preferably connected to each receiving chamber, and the first flow channel and the second flow channel form a complete air duct). In this way, the incoming air first enters the middle receiving chamber through the air inlet 1205' to dissipate heat from the air conditioning unit 1204', and then is discharged through the air outlet 1206', which effectively increases the air intake stroke and is conducive to improving the heat dissipation effect of the air conditioning unit 1204'. When heating, the heat generated by the condenser 11' and other components can be used to preheat the air entering the air conditioning unit; when cooling, the cold air generated by the air conditioning module can be used to cool the condenser 11' or to expel the heat generated by the power supply module and other components, without interfering with each other. Example 2

[0021] Please see Figure 4This embodiment provides a novel integrated air conditioning device for rail transit, including a protective cover 1202 installed on the top of the carriage 1. The protective cover 1202 houses a power supply module, a waste discharge module, an auxiliary reverse module, and an air conditioning module. This reduces the overall vehicle weight (a protective cover is required when installed in other locations), saves costs, and conserves space in other parts of the train. The waste discharge module, auxiliary reverse module, power supply module 11, and air conditioning unit are well-known technologies in this field and will not be described in detail here. The air conditioning module includes an air outlet 1201, an air inlet 1203, and an air conditioning unit. The air inlet 1203 is located at the top of the inner layer, and the air conditioning unit includes an air inlet pipe and an air outlet pipe. A first connecting pipe is fixedly connected between the air outlet 1201 and the air outlet pipe. The air outlet 1201 is located on both sides of the inner layer, and a second connecting pipe is fixedly connected to the top of the air inlet 1203. A heat exchange box is fixedly inserted into the side wall of the second connecting pipe, and the heat exchange box is fixedly inserted into the side wall of the air inlet pipe. The side wall of the power supply module is fixedly connected to the air inlet pipe. The heat exchanger has an air duct, and a vent pipe is fixedly connected to the bottom of the power supply module. A fan is installed on the side wall of the vent pipe, and a solenoid valve is fixedly connected to the other end of the vent pipe. The other end of the solenoid valve is fixedly connected to a first-row air duct, and a connecting pipe is fixedly connected between the vent pipe and the second connecting pipe. Two rectangular tubes are fixedly connected inside the heat exchanger, and the two rectangular tubes are respectively connected to the second connecting pipe and the air inlet pipe. Multiple heat exchange tubes are fixedly connected between the two rectangular tubes, and a second-row air duct is fixedly connected to the bottom of the heat exchanger. The upper end of the air inlet pipe passes through... The top of the protective cover is equipped with a one-way valve and a filter. The outlets of the second and first exhaust ducts are connected to the waste exhaust module, allowing air flowing out of the power supply module to be discharged to the waste exhaust module and then out to the atmosphere. Two independent air ducts are provided, allowing independent exhaust through the second and first exhaust ducts. During cooling, exhaust is through the first exhaust duct and the waste exhaust module; during heating, exhaust is through the second exhaust duct and the waste exhaust module, without interference. The heat exchange box is equipped with a sealing mechanism for sealing multiple heat exchange tubes and a heat dissipation mechanism for cooling the heat exchange tubes. By integrating the power supply module and the air conditioning module, during heating, the heat generated by the power supply module can preheat the air entering the air conditioning unit; during cooling, the heat generated by the power supply module is directly discharged, without interference. Simultaneously, blowing air and applying cooling water through the heat exchange tubes can pre-cool the air entering the air conditioning unit, making it more energy-efficient and environmentally friendly.

[0022] The sealing mechanism includes a telescopic pipe fixedly connected to the lower end of the connecting pipe, and a movable pipe fixedly connected to the lower end of the telescopic pipe. A first sealing plate is fixedly sleeved on the side wall of the movable pipe, and a rotating plate is rotatably connected to the side wall of the first sealing plate via a rotating mechanism. A second sealing plate is connected to the lower part of the heat exchange tube via a lifting mechanism. A through hole is opened on the top of the second sealing plate, and an opening and closing mechanism is provided on the side wall of the movable pipe. By closing the solenoid valve, the exhaust pipe is started to perform an exhaust operation, allowing the hot air generated in the power supply module to enter the movable pipe through the exhaust pipe, connecting pipe, and telescopic pipe. Under the action of air pressure, the movable pipe can be driven to move downward, so that the first sealing plate is in contact with the top of the two rectangular tubes. At the same time, the rotating mechanism... The mechanism drives the rotating plate to rotate downwards and fits against the top of the two rectangular tubes. Simultaneously, a lifting mechanism moves the second sealing plate upwards and fits against the bottom of the two rectangular tubes. At this point, the first sealing plate, rotating plate, second sealing plate, and two rectangular tubes seal multiple heat exchange tubes, forming a heat exchange area. Hot air then enters the heat exchange area through the moving pipe, preheating the air inside. The air is then discharged through the through-hole and the second exhaust duct. A temperature sensor detects the air temperature inside the intake duct, reducing the power consumption of the air conditioning unit. This allows the heat generated by the power supply module to preheat the air entering the air conditioning unit, resulting in greater energy efficiency and environmental friendliness.

[0023] The opening and closing mechanism is fixedly inserted into the fixed cover on the side wall of the moving pipe, and a sealing plate is connected inside the fixed cover through the first moving mechanism. The sealing plate is moved by the first moving mechanism to realize the opening and sealing of the moving pipe.

[0024] The first moving mechanism includes a first connecting block fixedly connected to the side wall of the sealing plate, and a push rod fixedly connected to the side wall of the first connecting block. An L-shaped block is fixedly connected to the side wall of one of the rectangular tubes, and the top of the L-shaped block is provided with an inclined surface. Two symmetrically arranged T-shaped guide rods are fixedly connected to the side wall of the first connecting block, and a second connecting block is sleeved on the side wall of the T-shaped guide rod. The second connecting block is fixed to the side wall of the fixed cover, and a first spring is sleeved on the side wall of each T-shaped guide rod. When the sealing plate moves downward, it can drive the push rod to move downward synchronously. When the push rod slides along the inclined surface to the side wall of the L-shaped block, it can push the sealing plate to move away from the fixed cover, and the first spring is compressed.

[0025] The rotating mechanism includes a fixed plate fixedly connected to the side wall of the first sealing plate, and a rotating plate rotatably connected to the side wall of the fixed plate via a rotating shaft. A gear is fixedly sleeved on the side wall of the rotating shaft, and an L-shaped rod is fixedly connected to the bottom of the push rod. A telescopic sleeve rod is fixedly connected to the other end of the L-shaped rod, and a connecting rod is fixedly connected to the other end of the telescopic sleeve rod. A rack is fixedly connected to the other end of the connecting rod, and the rack meshes with the gear. When the push rod moves, it can drive the telescopic sleeve rod to extend through the L-shaped rod. After extension, it can drive the rack to move through the connecting rod, causing the gear and the rotating shaft to rotate, thereby causing the rotating plate to rotate downward and fit against the top of the two rectangular tubes.

[0026] The lifting mechanism includes two symmetrically arranged guide rods fixedly connected between the rectangular tube and the heat exchange box, and a second sealing plate sleeved on the side wall of the guide rod. A second spring is sleeved on the side wall of each guide rod, and a bracket is fixedly connected to the side wall of one of the rectangular tubes. A guide wheel is rotatably connected to the side wall of the bracket, and a pull rope is slidably connected to the side wall of the guide wheel. The upper end of the pull rope is fixed to the side wall of the first sealing plate through a third connecting block, and the other end of the pull rope is fixed to the side wall of the second sealing plate through a fourth connecting block. When the first sealing plate moves downward, the pull rope can pull the second sealing plate upward and make it fit against the bottom of the two rectangular tubes. At the same time, the second spring is compressed.

[0027] The heat dissipation mechanism includes a working box fixedly inserted into the side wall of the first exhaust duct. Multiple blades are rotatably connected inside the working box via a rotating rod. The lower end of the rotating rod extends into the heat exchange box and is fixedly connected to a fan. The heat exchange box is equipped with a coating mechanism for applying cooling water to the surface of the heat exchange tubes. When cooling is required, hot air from inside the vehicle compartment is absorbed through the air inlet and the second connecting pipe. The solenoid valve is opened, and the hot air generated in the power supply module is discharged through the exhaust pipe and the first exhaust duct, no longer pushing the moving pipe downwards. The moving pipe can move downwards under the action of the telescopic pipe. Simultaneously, the sealing plate and the pushing rod can move and reset under the action of the first spring, thus sealing the moving pipe. The first and second sealing plates also move and reset, and the rotating plate rotates upwards and resets. When hot air passes through the first exhaust duct, it enters the working box and impacts the surface of the blades, causing the rotating rod to rotate. When the rotating rod rotates, it drives the fan to rotate, thus blowing air to dissipate heat from the heat exchange tubes, facilitating the pre-cooling of the hot air entering the air conditioning unit.

[0028] The coating mechanism includes a movable cover fitted onto the side wall of the heat exchange tube, with multiple sponge rings fixedly connected inside the movable cover. A first cotton thread is fixedly connected between the sponge rings. The side wall of the heat exchange box is provided with a second moving mechanism for moving the movable cover, and a water supply mechanism for supplying cooling water to the sponge rings. The movable cover is moved by the second moving mechanism, thereby causing the multiple sponge rings to slide on the surface of the heat exchange tube, thus coating the surface of the heat exchange tube with cooling water. Combined with the blowing of the fan, it can achieve a good pre-cooling effect on the hot air passing through the heat exchange tube.

[0029] The second moving mechanism includes a strip-shaped opening on the side wall of the heat exchange box, with a sliding block slidably connected inside the strip-shaped opening. The sliding block is fixed to the side wall of the moving cover, and a telescopic cover is fixedly connected between the sliding block and the strip-shaped opening. Two symmetrically arranged limiting rods are inserted into the side wall of the sliding block, and support blocks are fixedly connected to both ends of the limiting rods and the heat exchange box. A third spring is sleeved on the side wall of each limiting rod, and a connecting frame is fixedly connected to the top of the sliding block. A push plate is fixedly connected to the side wall of the connecting frame, and a cam is fixedly sleeved on the side wall of the rotating rod. When the rotating rod rotates, it can drive the cam to rotate. When the tip of the cam abuts against the side wall of the push plate, it can drive the moving cover to move through the connecting frame and the sliding block. At the same time, the third spring is compressed. When the tip of the cam passes the side wall of the push plate, the moving cover can move and reset under the action of the third spring. By repeating this process, the moving cover can drive multiple sponge rings to slide on the surface of the heat exchange tube.

[0030] The water supply mechanism includes a water storage tank fixedly connected to the side wall of the heat exchange box, and a flexible hose is fixedly connected between the water storage tank and the heat exchange box. A second cotton thread is fixedly connected to the side wall of the sponge ring, and the other end of the second cotton thread passes through the flexible hose and is inserted into the water storage tank. The cooling water in the water storage tank can be adsorbed onto the sponge ring through the first cotton thread and the second cotton thread, which facilitates the supply of cooling water.

[0031] Working principle: When in use, the power supply module 11 is integrated with the air conditioning module. When the temperature is low and the air conditioning module needs to heat, the air conditioning unit is started. At this time, the cold air in the compartment 1 enters the heat exchange box through the air inlet 1203 and the second connecting pipe, and then enters the air conditioning unit through the rectangular pipe and the heat exchange pipe for heating. The heated air can enter the air outlet 1201 through the air outlet pipe and the first connecting pipe and be blown into the compartment 1. At the same time, the solenoid valve is closed and the exhaust pipe is started to perform the exhaust operation, so that the hot air generated in the power supply module can enter the moving pipe through the exhaust pipe, the connecting pipe and the telescopic pipe. Under the action of air pressure, the moving pipe, the fixed cover and the sealing plate can be moved downward, and at the same time, the telescopic pipe is stretched.

[0032] When the sealing plate moves downward, it drives the push rod to move downward synchronously. When the push rod slides along the inclined plane to the side wall of the L-shaped block, it pushes the sealing plate to move away from the fixed cover. The first spring is compressed, and at this time, the moving tube is partially opened. At the same time, the first sealing plate is in contact with the top of the two rectangular tubes. When the push rod moves, it can drive the telescopic sleeve rod to extend through the L-shaped rod. After extension, it can drive the rack to move through the connecting rod, so that the gear and the rotating shaft rotate, thereby causing the rotating plate to rotate downward and contact with the top of the two rectangular tubes. Furthermore, when the first sealing plate moves downward, it can pull the second sealing plate upward through the pull rope and contact with the bottom of the two rectangular tubes. At the same time, the second spring is compressed. At this time, the first sealing plate, the rotating plate, the second sealing plate, and the two rectangular tubes seal the multiple heat exchange tubes, forming a heat exchange area.

[0033] Next, hot air can enter the heat exchange area through the moving pipe, preheat the air inside the heat exchange pipe, and then be discharged through the through hole and the second exhaust pipe. The temperature of the air in the air inlet pipe is detected by the temperature sensor, which reduces the power of the air conditioning unit. In this way, the heat generated when the power supply module is working can be used to preheat the air entering the air conditioning unit, which is more energy-saving and environmentally friendly.

[0034] When cooling is required, hot air inside the carriage 1 is absorbed through the air inlet and the second connecting pipe. The solenoid valve is opened, and the hot air generated in the power supply module is discharged through the exhaust pipe and the first exhaust pipe. The moving pipe is no longer pushed downward. The moving pipe can move downward under the action of the telescopic pipe. At the same time, the sealing plate and the push rod can move and reset under the action of the first spring, thereby blocking the moving pipe. At the same time, the first sealing plate and the second sealing plate move and reset, and the rotating plate rotates upward and resets.

[0035] Furthermore, when hot air passes through the first exhaust duct, it enters the working chamber and impacts the surface of the blades, causing the rotating rod to rotate. When the rotating rod rotates, it drives the fan to rotate, which in turn blows air onto the heat exchange tubes to dissipate heat, facilitating the pre-cooling of the hot air entering the air conditioning unit. At the same time, when the rotating rod rotates, it drives the cam to rotate. When the tip of the cam abuts against the side wall of the push plate, it moves the moving cover through the connecting frame and sliding block. Simultaneously, the third spring is compressed.

[0036] When the tip of the cam passes the side wall of the push plate, the moving cover can move and reset under the action of the third spring. By repeating this process, the moving cover can drive multiple sponge rings to slide on the surface of the heat exchange tube. The first and second cotton threads can cause the cooling water in the water storage tank to be absorbed onto the sponge rings, thereby coating the surface of the heat exchange tube with cooling water. Combined with the blowing of the fan, it can achieve a good pre-cooling effect on the hot air passing through the heat exchange tube. The temperature sensor detects the air temperature in the air inlet pipe, reducing the power of the air conditioning unit and making it more energy-efficient and environmentally friendly.
