Description

Technical Field

[0001] The present invention relates to the technical field of power control cabinets, and in particular to a multi-mode switching new energy power control cabinet with enhanced heat dissipation and moisture resistance. Background Art

[0002] With the rapid development of the global new energy industry, new energy power control cabinets, as core equipment, are widely used in scenarios such as photovoltaic power generation, wind energy storage, and distributed energy systems. However, this type of equipment is often deployed outdoors or in complex industrial environments, facing extreme challenges such as high temperature, high humidity, dust, and large temperature swings between day and night. Traditional control cabinets often rely on single-mode heat dissipation and moisture-proofing (such as natural ventilation, forced air cooling, or air conditioning), making them difficult to adapt to dynamic environmental changes. This can lead to problems such as overheating, condensation, and insulation degradation during long-term operation, directly impacting system reliability and service life.

[0003] While some existing control cabinets integrate dehumidification modules, these lack coordination with the cooling system, potentially leading to secondary condensation due to the inhalation of moist air through cooling. Furthermore, existing moisture-proofing technologies often rely on electrical control, which requires the coordinated operation of multiple components, including motors, sensors, controllers, and power supplies. This leads to high troubleshooting and maintenance costs. Summary of the Invention

[0004] Therefore, the present invention provides a multi-mode switching new energy power control cabinet with enhanced heat dissipation and moisture resistance.

[0005] The technical solution of the present invention is: a multi-mode switching new energy power control cabinet with enhanced heat dissipation and moisture resistance, comprising: a cabinet body, and a heat dissipation assembly and a drying box arranged in the cabinet body; the top surface of the cabinet body is provided with openings for heat dissipation;

[0006] The heat dissipation assembly includes a circulation box fixed to the cabinet, a refrigerator, a heat dissipation pipe and a cold pipe. The heat dissipation pipe is distributed inside the side of the cabinet, and the liquid inlet and outlet of the heat dissipation pipe are connected to the circulation box through the cold pipe.

[0007] The circulation box is provided with rotating blades for circulating the cooling liquid in the heat dissipation assembly, and the rotating blades are rotatably connected to the circulation box via a rotating shaft;

[0008] The cabinet side is provided with a plurality of heat dissipation mesh holes, the drying box is connected to the inner wall of the cabinet by sliding up and down, and the top of the drying box is connected to the upper surface of the cabinet by a first spring;

[0009] The cabinet is provided with a transmission assembly for driving the drying box to move downward to cover the heat dissipation mesh. The transmission assembly includes a gear rod, a gear, a first telescopic kit and a rotating rod. The gear rod is connected to the inner wall of the cabinet for vertical sliding, and one end of the gear rod is fixedly connected to the drying box.

[0010] The rotating rod is rotatably mounted on the circulation box, and a second bevel gear is provided at one end of the rotating rod to mesh with the first bevel gear provided on the rotating shaft for transmission.

[0011] The first telescopic assembly is composed of a spline rod sleeve and a spline rod that are slidably sleeved with each other, and a moisture memory material filled in the telescopic margin between the spline rod sleeve and the spline rod;

[0012] When the humidity exceeds the upper threshold, the humidity memory material deforms, causing the drying box to be connected to the rotating blade shaft. When the humidity exceeds the lower threshold, the humidity memory material returns to its original shape, causing the drying box to be disconnected from the rotating blade shaft.

[0013] The spline rod sleeve is fixedly connected to the other end of the rotating rod, the gear is fixedly connected to the spline rod, and the gear is controlled to engage or disconnect with the gear rod through the humidity memory material according to the humidity change.

[0014] Description: Through the above-mentioned setting, dynamic monitoring is achieved by using special humidity-sensitive memory materials, which control the downward movement of the drying box to close the mesh and isolate external moisture. Specifically, when the humidity exceeds the upper threshold, deformation occurs, causing the drying box to be connected to the rotating blade shaft, causing the drying box to open and move downward. When the humidity of the humidity memory material exceeds the lower threshold, the drying box returns to its original state, disconnecting the drying box from the rotating blade shaft. The drying box then returns to its original state under the action of the spring, and at the same time, the heat dissipation assembly forms a high-efficiency liquid cooling cycle.

[0015] Furthermore, a top cover is provided on the top of the cabinet, and the top cover is connected to the top surface of the cabinet through a heat dissipation mesh cover.

[0016] Note: The top cover can prevent rainwater, fallen leaves and other impurities from entering the cabinet.

[0017] Furthermore, a first rotating fan is rotatably provided in the cabinet located at the opening; a cover plate is arranged above the opening; a first connecting rod connected to the cover plate is provided on the drying box for synchronously opening and closing the opening according to the opening and closing of the heat dissipation mesh of the drying box; the first connecting rod is connected to the top surface of the cabinet through a fourth spring.

[0018] Note: Through the above-mentioned setting, heat dissipation can be assisted and the opening and the heat dissipation mesh can be closed or opened synchronously through the first connecting rod.

[0019] Furthermore, the rotating shaft passes through the top surface of the circulation box and is provided with a second rotating fan; the drying box includes a first shell fixed to the inner wall of the cabinet through the end edge, and a second shell slidably connected to the cabinet, the first shell and the second shell are assembled and a desiccant is fixed in the second shell, the first connecting rod is connected to the second shell, and a slag net for blocking the desiccant is fixed on the second shell.

[0020] Note: Through the above settings, the drying box can be moved downward to open and start drying adsorption at the same time, and moved upward to close to avoid the desiccant being affected by the environment or the adsorption causing poor drying effect when the humidity does not exceed the standard.

[0021] Furthermore, a notch is provided at the upper end of the gear rod for disconnecting the meshing state with the gear.

[0022] Note: The notch at the top of the gear rod allows the gears to disengage under certain conditions to avoid mechanical jamming or excessive wear.

[0023] Furthermore, the inner wall of the cabinet is provided with a clamping piece for clamping with the protrusion, and the clamping piece includes a clamping block that is slidably connected to the cabinet left and right to clamp the second shell, and a second telescopic kit that is fixed to the cabinet at one end and connected to the clamping block at the other end. The second telescopic kit is composed of a telescopic rod sleeve and a telescopic rod that are slidably connected to each other, and a humidity memory material filled in the telescopic margin between the telescopic rod sleeve and the telescopic rod. The clamping block is clamped with the groove on the second shell by controlling the expansion and contraction according to humidity changes through the humidity memory material.

[0024] Note: The above setting can push the card block and the protrusion to engage according to the humidity change, that is, it can lock the position of the drying box in a high humidity environment to enhance the moisture-proof effect.

[0025] Furthermore, a guide groove is vertically provided at the bottom of the cabinet side wall, a first air bag is provided at the lower end of the guide groove, and a slider is provided on the gear rod for synchronously squeezing the first air bag when the drying box closes the heat dissipation mesh.

[0026] The drying box is divided into a left chamber and a right chamber by a spacer. A feed bin door is provided at the bottom end of the left chamber of the drying box, and a discharge bin door is provided at the bottom end of the right chamber of the drying box.

[0027] A filler assembly is provided at the bottom of the cabinet side wall for partially replacing the desiccant in the drying box by squeezing the first airbag. The filler assembly includes a box body for cooperating with the feed bin door to feed the internal desiccant into the left chamber. A feed plate is provided in the box body that moves up and down. A second airbag is connected to the bottom surface of the feed plate. The second airbag is connected to the first airbag via a connecting pipe.

[0028] A connecting box is provided on the outer wall of the cabinet just below the discharge bin door, which penetrates into the cabinet. The desiccant in the discharge bin door is discharged to the outside of the cabinet through the connecting box for recovery or reuse. Both the feed bin door and the discharge bin door are bin doors that can be opened by pushing toward the inside of the drying box.

[0029] Note: Through the above arrangement, desiccant can be added synchronously during the movement of the drying box to achieve partial replacement of the desiccant in the drying box, thereby improving the drying effect. Specifically, the gear rod squeezes the first airbag, and the gas in the first airbag flows to the second airbag. The second airbag extends to push the feed plate upward, pushing the desiccant above it into the drying box through the feed bin door, thereby realizing the feeding process. At the same time, the desiccant in the left chamber of the drying box is squeezed into the right chamber through the upper part, and then discharged through the discharge bin door and discharged to the outside of the cabinet.

[0030] Furthermore, the refrigerator is arranged on the outer wall of the cabinet; a drying box is provided outside the cabinet for using the refrigerator to heat, dry and recycle the desiccant discharged from the drying box. The drying box is connected to the connecting box arranged on the outer wall of the cabinet through a first through pipe, and the recovery box is connected to the box body through a second through pipe, and the second through pipe is located above the feed plate. The connecting box extends into the cabinet and has a feed port that is plugged and connected to the drying box.

[0031] Note: Through the above-mentioned setting, the heat energy emitted from the external component of the refrigerator can be used to heat the desiccant for reuse, so that heat energy can be saved and the desiccant can be automatically recycled and reused.

[0032] Furthermore, the feed plate is provided with a baffle to prevent the second through pipe from feeding material below the feed plate.

[0033] Note: The above arrangement can prevent the second through-pipe from feeding material below the feed plate, thereby preventing the feed plate from being unable to push the desiccant below it for feeding.

[0034] The beneficial effects of the present invention are:

[0035] The present invention can isolate moisture and dry the cabinet by moving the drying box downward to close the mesh when the humidity is too high. At the same time, the heat dissipation assembly forms an efficient liquid cooling cycle, and the air flow in the cabinet is enhanced in combination with the second rotating fan. In addition, the first memory material deforms when the ambient humidity exceeds the threshold, pushing the gear and the gear rod to engage. At the same time, the second memory material responds to the humidity change to push the card block and the protrusion to engage, which can lock the position of the drying box in a high-humidity environment to enhance the moisture-proof effect.

DETAILED DESCRIPTION

[0045] The present invention will be further described in detail below in conjunction with specific implementation methods to better demonstrate the advantages of the present invention.

[0046] Example 1: Figure 1 、 Figure 2 As shown, a multi-mode switching new energy power control cabinet with enhanced heat dissipation and moisture resistance includes: a cabinet body 1, and a heat dissipation assembly 2 and a drying box 3 arranged in the cabinet body 1; the top surface of the cabinet body 1 is provided with openings for heat dissipation;

[0047] The heat dissipation assembly 2 includes a circulation box 29 fixed to the cabinet 1, a refrigerator 291, a heat dissipation pipe and a cold pipe 22. The heat dissipation pipe is distributed inside the side of the cabinet 1, and the liquid inlet and outlet of the heat dissipation pipe are connected to the circulation box 29 through the cold pipe 22 respectively. A top cover 11 is provided on the top of the cabinet 1, and the top cover 11 is connected to the top surface of the cabinet 1 through a heat dissipation mesh cover 12; a first rotating fan 36 is provided in the cabinet 1 at the opening; a cover plate 14 is provided above the opening, and a first connecting rod 35 is provided on the drying box 3 and is connected to the cover plate 14 for synchronously opening and closing the opening according to the opening and closing of the heat dissipation mesh hole 13 of the drying box 3; the first connecting rod 35 is connected to the top surface of the cabinet 1 through a fourth spring 351;

[0048] like Figure 2 and Figure 3 As shown, the circulation box 29 is provided with a rotating blade 21 for circulating the cooling liquid in the heat dissipation assembly 2, and the rotating blade 21 is rotatably connected to the circulation box 29 through a rotating shaft; a plurality of heat dissipation mesh holes 13 are provided on the side of the cabinet 1, and the drying box 3 is slidably connected to the inner wall of the cabinet 1 up and down, and the top of the drying box 3 is connected to the top surface of the cabinet 1 through a first spring 31; a transmission component is provided in the cabinet 1 for driving the drying box 3 to move downward to block the heat dissipation mesh holes 13, and the transmission component includes a gear rod 51, a gear 52, a first telescopic kit 53 and a rotating rod 26, the gear rod 51 is slidably connected to the inner wall of the cabinet 1 up and down, and one end of the gear rod 51 is fixedly connected to the drying box 3, the rotating rod 26 is rotatably set on the circulation box 29, and a second bevel gear 25 is provided at one end of the rotating rod 26 to mesh with the first bevel gear 24 provided on the rotating shaft for transmission; the upper end of the gear rod 51 is provided with a notch for disconnecting the meshing state with the gear 52;

[0049] like Figure 3 As shown, the inner wall of the cabinet 1 is provided with a clamping member 4 for clamping with the protrusion 34. The clamping member 4 includes a clamping block 41 that is slidably connected to the cabinet 1 left and right and is used to clamp the second shell 32, and a second telescopic kit 42 fixed to the cabinet 1 at one end and connected to the clamping block 41 at the other end. The second telescopic kit 42 is composed of a telescopic rod sleeve and a telescopic rod that are slidably connected to each other, and a humidity memory material filled in the telescopic margin between the telescopic rod sleeve and the telescopic rod. The clamping block 41 is clamped with the groove on the second shell 32 by the humidity memory material to control the expansion and contraction according to the humidity change.

[0050] like Figure 4As shown, the first telescopic kit 53 is composed of a spline rod sleeve and a spline rod that are slidably sleeved with each other, and a humidity memory material filled in the telescopic margin between the spline rod sleeve and the spline rod (the humidity memory material is a PVA-TPU composite material, which is a solution mixing / casting method used by Wu et al. in the prior art with polyvinyl alcohol (PVA) submicron particles as the hydrophilic phase and thermoplastic polyurethane (TPU) as the elastic source and matrix, which can produce a reversible modulus change and maintain a shape recovery rate of 97-98%); the humidity memory material deforms when the humidity exceeds the upper threshold value, causing the drying box 3 to be transmission-connected to the rotating shaft of the rotating blade 21; the humidity memory material returns to its original shape when the humidity exceeds the lower threshold value, causing the drying box 3 to be disconnected from the rotating shaft of the rotating blade 21; the spline rod sleeve is fixedly connected to the other end of the rotating rod 26, and the gear 52 is fixedly connected to the spline rod. The gear 52 is controlled to telescope and engage or disconnect with the gear rod 51 according to the humidity change through the humidity memory material;

[0051] like Figure 5 As shown, the rotating shaft passes through the top surface of the circulation box 29 and is provided with a second rotating fan 23; the drying box 3 includes a first shell 33 fixed to the inner wall of the cabinet 1 through the end edge, and a second shell 32 slidably connected to the cabinet 1, the first shell 33 and the second shell 32 are assembled and arranged, and a desiccant is fixed in the second shell 32, the first connecting rod 35 is connected to the second shell 32, and a slag net 321 for blocking the desiccant is fixed on the second shell 32;

[0052] The working principle of the above device is:

[0053] First, the opening motor in the cabinet 1 drives the rotating blade 21 in the circulation box to rotate, so that the cold liquid circulates in the circulation box and the cold pipe 22, reducing the temperature in the cabinet 1; at the same time, since the second rotating fan 23 and the rotating blade 21 have the same rotation axis, that is, Figure 2 The output end of the motor is provided with a rotating shaft, one end of which passes through the circulation box and is fixed to the second rotating fan 23, and the second rotating fan 23 can assist in heat dissipation;

[0054] When the humidity exceeds the standard (for example, 70% in the embodiment of the present invention), the first telescopic kit 53 provided with the humidity memory material is extended and deformed, pushing the gear 52 to engage with the gear rod 51, causing the gear rod 51 to move downward, and the gear rod 51 drives the second shell 32 to move downward for drying. The second shell 32 moves downward to the clamp 4. At this time, the humidity memory material causes the second telescopic kit 42 to extend and deform, and the clamp 41 clamps the drying box 3; the second shell 32 moves downward, blocking a number of heat dissipation meshes 13 for dehumidification, thereby reducing the moisture in the outside air. Particles or impurities enter the cabinet 1, causing problems such as poor dehumidification effect; when the second shell 32 moves downward, the first connecting rod 35 causes the cover plate 14 to move downward to cover the opening on the top surface of the cabinet 1. When the humidity drops below 20%, the humidity memory material returns to its original state, so that the first telescopic kit 53 and the second telescopic kit 42 return to their original state, the gear 52 disengages from the gear rod 51, and the clamping block 41 disconnects from the drying box 3; the first spring 31 is used to move the second shell 32 upward to return to its original position, and the first connecting rod 35 and the cover plate 14 return to their original position.

[0055] Example 2: This example differs from Example 1 in that:

[0056] like Figure 6 and Figure 7 As shown, a guide groove 15 is vertically provided at the bottom of the side wall of the cabinet 1, and a first air bag 151 is provided at the lower end of the guide groove 15, and a slider 511 is provided on the gear rod 51 for synchronously squeezing the first air bag 151 when the drying box 3 closes the heat dissipation mesh 13. The interior of the drying box 3 is divided into a left chamber and a right chamber by arranging a spacer 37. A feed bin door 39 is provided at the bottom end of the left chamber of the drying box 3, and a discharge bin door 38 is provided at the bottom end of the right chamber of the drying box 3. Both the discharge bin door 38 and the feed bin door 39 are bin doors that can be pushed into the interior of the drying box 3 in the prior art (similar to the one-way opening door structure in the prior art). Specifically, for example, the feed bin door 39 can be opened by squeezing the protruding end edge on the box body 16, and the discharge bin door 38 can be opened by squeezing the protruding end edge on the connecting box 163.

[0057] A packing assembly is provided at the bottom of the side wall of the cabinet 1 for partially replacing the desiccant in the drying box 3 by squeezing the first airbag 151. The packing assembly includes a box body 16 for cooperating with the feed bin door 39 to feed the internal desiccant into the left chamber. A feed plate 161 is provided in the box body 16 for moving up and down. The bottom surface of the feed plate 161 is connected to a second airbag 153. The second airbag 153 is a vertically telescopic airbag and is connected to the first airbag 151 through a connecting pipe 152.

[0058] A connecting box 163 is provided on the outer wall of the cabinet 1 directly below the discharge bin door 38, which penetrates into the cabinet 1. The desiccant in the discharge bin door 38 is discharged to the outside of the cabinet 1 through the connecting box 163 for recycling or reuse.

[0059] The working principle of this embodiment is roughly the same as that of embodiment 1, except that:

[0060] As the drying box 3 moves downward, the gear rod 51 also moves downward. When the gear rod 51 reaches the lower end of the guide groove 15, it squeezes the first air bag 151. The gas in the first air bag 151 flows to the second air bag 153 through the connecting pipe 52. The second air bag 153 extends, pushing the feed plate 161 upward. The feed plate 161 pushes the desiccant above it to move upward and enter the left chamber of the drying box through the feed bin door 39 (preferably, the top of the box body 16 is provided with a bin door that can be pushed outward (i.e. upward) to open). After entering the left chamber, the desiccant squeezes the desiccant above it, and the desiccant in the upper part of the drying box 3 is squeezed and moved to the right chamber. At the same time, the discharge bin door 38 contacts and squeezes the connecting box 163, causing the discharge bin door 38 to open, and the desiccant inside it falls into the connecting box 163. Outsiders use the connecting box 163 to dispose of the used dryer and regularly put new desiccant into the box body 16.

[0061] Example 3: This example differs from Example 1 in that:

[0062] like Figure 8 As shown, the refrigerator 291 adopts a commercially available one, such as a semiconductor refrigerator, and the refrigerator 291 is arranged on the outer wall of the cabinet 1; the outside of the cabinet 1 is provided with a drying box 164 for heating, drying and recycling the desiccant discharged from the drying box 3 using the hot end of the refrigerator 291, and the drying box 164 is connected to the connecting box 163 arranged on the outer wall of the cabinet 1 through a first through-tube, and the recovery box 164 is connected to the box body 16 through a second through-tube 162, and the second through-tube 162 is located above the feed plate 161, the connecting box 163 extends into the cabinet 1 and has a feed port connected to the drying box 3 by plugging, and a warehouse door for one-way feeding into the box body 16 is provided in the second through-tube 162 (a warehouse door that can be opened one-way in the prior art), which can prevent the desiccant from absorbing moisture through the second through-tube 162 and affecting the quality of the desiccant stored in the connecting box 163; the feed plate is provided with a baffle to prevent the second through-tube from feeding to the bottom of the feed plate.

[0063] The working principle of this embodiment is roughly the same as that of embodiment 2, except that:

[0064] After the desiccant falls into the connecting box 163, it falls into the drying box 164 through the first through pipe. The drying box 164 contacts the heat exchange box 291 for heat exchange. The drying box 164 absorbs the heat of the heat exchange box 291 to heat the desiccant in the drying box 164 for reuse. The heated and dried desiccant falls into the box body 16 through the second through pipe 162 for reuse. At the same time, the baffle can prevent the second through pipe 162 from feeding to the bottom of the feed plate 161, thereby preventing the feed plate 161 from being unable to push the desiccant below it for feeding.
