Description

Technical Field

[0001] This invention relates to the field of power cabinets, specifically a moisture-proof integrated power distribution cabinet structure. Background Technology

[0002] Power distribution cabinets, also known as cabinet heads, are power management devices designed specifically for communication equipment rooms or data centers. They are usually located at the end of a cabinet row or at a designated location and are responsible for centralized power distribution to the equipment in the entire row of cabinets. They also integrate monitoring, protection, and energy data acquisition functions.

[0003] In the existing power distribution cabinet structure, the fan is usually placed at the top for cooling. Cool air is introduced from the top of the power distribution cabinet, which easily causes condensation on the top of the cabinet after a period of time. The condensation can drip into the internal electrical components of the power distribution cabinet, causing the components to become damp and potentially leading to dangerous situations such as short circuits. Summary of the Invention

[0004] The purpose of this invention is to provide a moisture-proof integrated power distribution cabinet structure to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a moisture-proof integrated power distribution cabinet structure, including a cabinet body, the cabinet body being composed of a base, a top cover, a back panel and two side panels;

[0006] A primary heat dissipation assembly is provided on the inner side of each side plate. The primary heat dissipation assembly includes a first cooling fan fixed on one of the side plates and a first air guide plate on the other side plate that is directly opposite the position of the first cooling fan. The first air guide plate is fixed on a cooling block, and the cooling block is fixed to the side plate. A first ventilation hole is opened on both side plates, and each first ventilation hole corresponds to the position of one of the first cooling fans. A cooling cavity is opened vertically through the cooling block, and several heat dissipation fins protruding from the cooling block are fixed in the cooling cavity.

[0007] A water collection tank fixed to the base is provided at the bottom of the cooling block;

[0008] A secondary heat dissipation component is provided between the two primary heat dissipation components. The secondary heat dissipation component consists of a blower mechanism and an exhaust mechanism. The exhaust mechanism includes a baffle fixed between the side plates. A second air guide plate and a straight plate are fixed at the bottom of the baffle. The second air guide plate and the straight plate form an air inlet. A connecting port is opened on the baffle to connect with the air inlet. An exhaust block is fixed on the baffle. An exhaust cavity is opened through the exhaust block. One side of the exhaust cavity is connected to a discharge hole, and the other side of the exhaust cavity is connected to the connecting port.

[0009] A temperature detector and a control terminal are installed on the back panel.

[0010] Preferably, the two primary heat dissipation components are arranged symmetrically at the center.

[0011] Preferably, a sponge is installed inside the water collection tank, and a drain hole penetrating the base is provided at the bottom of the water collection tank.

[0012] Preferably, the blower mechanism includes a mounting bracket fixed on the base, at least one secondary cooling fan is fixedly mounted on the mounting bracket, and air inlets facing the primary heat dissipation component are opened on both sides of the mounting bracket.

[0013] Preferably, two notches are provided on the baffle, and the notches are located directly above the cooling block.

[0014] Preferably, a frame fixed between the two side plates is provided at the bottom of the exhaust mechanism, and at least one layer of mesh is installed inside the frame.

[0015] Preferably, the mesh is made of nylon or polyester fiber.

[0016] Preferably, a partition is fixed on the baffle, and a heat insulation layer is installed between the partition and the exhaust block. The heat insulation layer is made of polystyrene foam or polyurethane foam.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. This application divides the heat dissipation part into two parts. The first part is a primary heat dissipation component set inside each side panel. A secondary heat dissipation component is set between the two primary heat dissipation components. The secondary heat dissipation component consists of a blower mechanism and an exhaust mechanism. Secondary heat dissipation prevents excessive condensation from being generated at one time, thus preventing sudden condensation from causing severe damage to the electronic components inside the cabinet.

[0019] 2. The primary heat dissipation component includes a cooling fan fixed to one side panel and an air guide plate on the other side panel, directly opposite the cooling fan. The air guide plate is fixed to the cooling block, which is also fixed to the side panel. A ventilation hole corresponding to the cooling fan's position is provided on the side panel for air intake. A cooling chamber runs vertically through the cooling block, containing several heat sinks extending out of it. When heat dissipation is needed, the cooling fan is activated, drawing outside air through the ventilation hole and blowing it onto the air guide plate. The air is then directed into the cooling chamber by the air guide plate, dissipating heat from the heat sinks within. Because the heat sinks are located on the outside of the cooling block, they continuously absorb heat from the cabinet and direct it into the cooling chamber for further cooling. This design ensures that initial heat dissipation occurs within the cooling chamber, and most of the condensate from the hot and cold contact accumulates on the surface of the heat sinks, preventing interference with electrical components within the cabinet.

[0020] 3. A water collection tank fixed to the base is installed at the bottom of the cooling block. A sponge is installed inside the water collection tank. The condensate will flow into the sponge along the inner wall of the cooling chamber and be collected, avoiding the subsequent impact of the condensate.

[0021] 4. A secondary heat dissipation component is installed between the two primary heat dissipation components. The secondary heat dissipation component consists of a blower mechanism and an exhaust mechanism. The exhaust mechanism includes a baffle fixed between the side panels. A second air guide plate and a straight plate are fixed to the bottom of the baffle. The second air guide plate and the straight plate form an air inlet. A connecting port is opened on the baffle to connect with the air inlet. An exhaust block is fixed on the baffle. An exhaust cavity is opened through the exhaust block. One side of the exhaust cavity is connected to the exhaust hole, and the other side of the exhaust cavity is connected to the connecting port. A frame is fixed between the two side panels at the bottom of the exhaust mechanism. At least one layer of mesh is installed inside the frame. When the blower mechanism blows hot air from the air outlet, the connecting port, the exhaust cavity, and finally out of the exhaust hole, the condensate generated is blocked and absorbed along the second air guide plate and the straight plate and finally falls onto the surface of the mesh. This ensures that the condensate in the entire heat dissipation process will not affect the electrical components inside the cabinet. Attached Figure Description

[0031] Combined with appendix Figures 1-7 The aforementioned moisture-proof integrated power distribution cabinet structure includes a cabinet body 10, which is composed of a base 12, a top cover 13, a back panel 16, and two side panels 11. Various electrical components are installed on the back panel 16.

[0032] See Figure 1 and Figure 2To ensure minimal moisture during heat dissipation, the heat dissipation components inside the cabinet have been optimized. Specifically, the heat dissipation components are divided into two parts. The first part consists of a primary heat dissipation assembly 50 located inside each side panel 11. To ensure heat dissipation covers the entire cabinet 10, two primary heat dissipation assemblies 50 are arranged symmetrically. Each primary heat dissipation assembly 50 is responsible for dissipating heat from half of the cavity inside the cabinet 10. Each primary heat dissipation assembly 50 includes a primary cooling fan 31 fixed to one of the side panels 11, and a primary air guide plate 29 on the other side panel 11 directly opposite the primary cooling fan 31. The primary air guide plate 29 is fixed to a cooling block 32, which is fixed to the side panel 11. Both side panels 11 have ventilation holes 14, each corresponding to one of the primary cooling fans 31. A cooling chamber 42 is formed through the cooling block 32 from top to bottom. Several heat sinks 24 protruding from the cooling block 32 are fixed in the cooling chamber 42. When heat dissipation is required, the first cooling fan 31 is activated to draw outside air through the first ventilation hole 14 and blow it onto the first air guide plate 29. The air is then guided by the first air guide plate 29 and blown into the cooling chamber 42 to dissipate heat from the heat sinks 24 inside the cooling chamber 42. Since the heat sinks 24 are located on the outside of the cooling block 32, they can continuously absorb heat from the cabinet 10 and conduct it into the cooling chamber 42 for heat dissipation. The advantage of this is that the initial heat dissipation occurs within the cooling chamber 42. In this way, most of the condensate generated by the contact between hot and cold water will accumulate on the surface of the heat sinks 24 inside the cooling chamber 42, without interfering with the electrical components inside the cabinet 10.

[0033] To handle the condensate in the cooling chamber 42, a water collection tank 36 fixed to the base 12 is provided at the bottom of the cooling block 32. A sponge 37 is installed in the water collection tank 36, and the condensate will flow into the sponge 37 along the inner wall of the cooling chamber 42 and be collected.

[0034] Specifically, a drain hole 38 penetrating the base 12 is provided at the bottom of the water collection tank 36. The drain hole 38 is used to drain condensate. The sponge 37 needs to be replaced regularly.

[0035] A secondary heat dissipation component is provided between the two primary heat dissipation components 50. The secondary heat dissipation component consists of a blower mechanism 60 and an exhaust mechanism 70. The exhaust mechanism 70 includes a baffle 28 fixed between the side plates 11. A second air guide plate 27 and a straight plate 44 are fixed at the bottom of the baffle 28. The second air guide plate 27 and the straight plate 44 form an air inlet. A connecting port 34 is opened on the baffle 28 to connect with the air inlet. An exhaust block 33 is fixed on the baffle 28. An exhaust cavity 35 is opened through the exhaust block 33. One side of the exhaust cavity 35 is connected to the discharge hole 15, and the other side of the exhaust cavity 35 is connected to the connecting port 34.

[0036] The blower mechanism 60 includes a mounting bracket 21 fixed on the base 12. At least one secondary cooling fan 22 is fixedly mounted on the mounting bracket 21. Air collection ports 39 are opened on both sides of the mounting bracket 21 facing the primary heat dissipation component 50. The air collection ports 39 facilitate the upward blowing of the air discharged from the primary heat dissipation component 50.

[0037] A temperature detector 43 and a control terminal are installed on the back panel 16. The temperature detector 43 is used to detect the temperature inside the cabinet 10 and feed it back to the control terminal. The control terminal controls each cooling fan to start for heat dissipation.

[0038] Each cooling fan uses a DC fan, which has a relatively simple structure, mature technology, and low procurement cost. The fan has a built-in small motor and can be started with just power.

[0039] Two notches 30 are made on the baffle 28, and the notches 30 are located directly above the cooling block 32 to prevent the air guided by the first air guide plate 29 from being blocked by the baffle 28.

[0040] Further optimization involves a frame 25 fixed between the two side plates 11 at the bottom of the exhaust mechanism 70, with at least one layer of mesh 26 inside the frame 25. When the blower mechanism 60 blows hot air from the air outlet, the connecting port 34, the exhaust chamber 35, and finally out of the discharge hole 15, condensation will also be generated. The condensation will flow along the second air guide plate 27 and the straight plate 44 and finally fall onto the surface of the mesh 26 where it will be blocked and absorbed (due to the surface tension of the liquid, the water droplets will be blocked by the mesh openings on the mesh 26). This ensures that the condensation during the entire heat dissipation process will not affect the electrical components inside the cabinet 10.

[0041] The mesh 26 is preferably made of a water-absorbing material, commonly nylon and polyester fiber.

[0042] A partition 41 is fixed on the baffle 28, and a heat insulation layer 40 is installed between the partition 41 and the exhaust block 33. The presence of the heat insulation layer 40 can prevent the hot air discharged from the exhaust cavity 35 from affecting the cold air drawn in by the first cooling fan 31, thus preventing the heat dissipation effect from being affected.

[0043] The commonly used materials for the insulation layer 40 include polystyrene foam and polyurethane foam.

[0044] How to use:

[0045] In use, the necessary electronic components and brackets are mounted on the back panel 16. The temperature detector 43 is used to detect the temperature inside the cabinet 10 and feed it back to the control terminal. When the temperature is too high, the control terminal controls the first cooling fan 31 and the second cooling fan 22 to start.

[0046] The first cooling fan 31 is activated to draw outside air through the first ventilation hole 14 and blow it onto the first air guide plate 29. The air is then guided by the first air guide plate 29 and blown into the cooling chamber 42 to dissipate heat from the heat sink 24 portion inside the cooling chamber 42. Since the heat sink 24 portion is located outside the cooling block 32, the heat sink 24 portion outside the cooling block 32 can continuously absorb heat from the cabinet 10 and guide it into the heat sink 24 portion inside the cooling chamber 42 for heat dissipation. Most of the condensate generated by the contact between hot and cold water will accumulate on the surface of the heat sink 24 portion inside the cooling chamber 42. The condensate will flow along the inner wall of the cooling chamber 42 into the sponge 37 and be collected.

[0047] The second cooling fan 22 absorbs the air discharged from the cooling chamber 42 and carries out the hot air between the electronic components of the back plate 16. The hot air is then blown out from the air outlet, the connecting port 34, the exhaust chamber 35, and finally from the discharge hole 15. When condensation occurs, the condensation flows along the second air guide plate 27 and the straight plate 44 and finally falls onto the surface of the mesh 26 where it is blocked and absorbed.

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
