Description

Technical Field

[0001] The invention belongs to the technical field of power cabinets and relates to an energy-saving and heat-dissipating communication cabinet. Background Art

[0002] In the field of communications, there are many scenarios where power cabinets are needed for power supply. For example, in construction, maintenance or places where power supply is difficult, wall-mounted power cabinets are often used to meet the needs of rapid construction. The communication power supply system is the heart of the communication system. A stable and reliable communication power supply system is the key to ensuring the safe and reliable operation of the communication system.

[0003] Since most power cabinets are installed outdoors, they are exposed to sunlight, which causes the power cabinet and its internal equipment to heat up. In addition, the power cabinet itself contains many power supply devices that generate a lot of heat during operation. In order to dissipate the heat of the power cabinet, cooling fans and other devices are usually installed on the cabinet to dissipate the heat inside the cabinet through air flow. In addition, temperature monitoring devices need to be installed on the cabinet to monitor the temperature and control the start and stop of the cooling fan, which consumes a lot of electricity. At the same time, during the process of the cooling fan ventilating and dissipating the heat into the cabinet, dust, water vapor and other substances in the external environment may also enter the cabinet with the airflow, causing the components inside the cabinet to be contaminated and shortening their service life. Summary of the invention

[0004] The object of the present invention is to provide an energy-saving and heat-dissipating communication cabinet, which can realize automatic heat dissipation of the cabinet and save electric energy.

[0005] In order to achieve the above-mentioned object, the basic scheme of the present invention is: an energy-saving heat dissipation communication cabinet, comprising a cabinet body and a heat dissipation mechanism arranged outside the cabinet body, the heat dissipation mechanism comprising a shell, a water tank and a sprinkler, the shell being a solid frame structure;

[0006] The bottom of the cabinet is fixedly connected to the inner bottom of the shell, and there is a gap between the other side walls of the cabinet and the shell;

[0007] The water tank is installed on the outer top of the shell, and the sprinkler is arranged on the inner top of the shell;

[0008] A connecting hole is provided at the top of the shell, and a first sealing mechanism is provided at the connecting hole. The first sealing mechanism includes a transverse groove and a baffle for sealing the connecting hole. The transverse groove is provided on both sides of the connecting hole, and both ends of the baffle are respectively located in the transverse grooves on both sides of the connecting hole. The baffle is sealingly and slidingly connected to the transverse groove. A space formed by one end of the baffle and the inner wall of the transverse groove on one side of the connecting hole contains thermal expansion and contraction gas. A through hole is provided on the side of the baffle close to the thermal expansion and contraction gas. The through hole can be placed in the transverse groove or overlap with the connecting hole. The bottom of the water tank is connected to the top of the connecting hole, and the sprinkler is connected to the bottom of the connecting hole.

[0009] The working principle and beneficial effects of this basic solution are as follows: a shell is set outside the cabinet to facilitate heat insulation and reduce the heat transferred to the cabinet from sunlight. A water tank is set on the top of the cabinet to provide shade and reduce the impact of sunlight on the cabinet. The water tank is connected to the shell through a connecting hole. There is a gap between the shell and the cabinet, and the water in the water tank can flow into the gap through the connecting hole to achieve water cooling of the cabinet. Compared with the heat dissipation method of the cooling fan, it prevents impurities such as dust or water vapor in the external environment from entering the cabinet, which is convenient for use.

[0010] A first sealing mechanism is provided at the connection hole. When heat dissipation is not required, the baffle can seal the connection hole. When the thermal expansion and contraction gas in the transverse groove is heated, it indicates that the temperature of the side wall of the shell is too high. It is judged that the external sunlight temperature is too high or the temperature rises due to heating of the equipment in the cabinet. The thermal expansion and contraction gas expands and pushes the baffle to the outside of the corresponding side transverse groove. The movement of the baffle can gradually make the through hole on it overlap with the connection hole, so that the water in the water tank flows through the connection hole into the shell, realizing automatic water cooling and heat dissipation, reducing power consumption, and facilitating energy saving. Injecting water into the gap between the shell and the cabinet can play a heat-insulating role and reduce the temperature impact of sunlight on the cabinet.

[0011] Furthermore, a first elastic member is provided in the space between the baffle plate and the transverse groove where the thermally expanding and contracting gas is located. One end of the first elastic member is fixedly connected to the baffle plate, and the other end is fixedly connected to the inner wall of the transverse groove.

[0012] In this way, when the temperature drops, the thermally expanded and contracted gas recovers, and the elastic force of the first elastic member helps the baffle to return to its original position.

[0013] Furthermore, the outer wall of the transverse groove containing the thermally expanding and contracting gas is provided with a heat absorbing material.

[0014] The heat absorbing material is provided to concentrate the heat and control the volume change of the gas due to thermal expansion and contraction.

[0015] Furthermore, the sprinkler includes a tube body with a sealed bottom, a plurality of first sprinkler holes arranged on the tube wall of the tube body, and a plurality of second sprinkler holes arranged at the bottom of the tube body;

[0016] A second sealing mechanism is provided at the first watering hole, and the sealing mechanism includes a groove and a block for blocking the watering hole. The groove is arranged on the upper and lower sides of the first watering hole. The connection structure between the block and the groove is the same as the connection structure between the baffle and the transverse groove in the first sealing mechanism. A water outlet hole is provided on the side of the block close to the thermal expansion and contraction gas in the corresponding groove, and the water outlet hole is placed in the transverse groove or coincides with the corresponding first watering hole.

[0017] The water flowing through the connecting hole enters the tube body and can fall into the outer shell from the second water sprinkling hole at the bottom of the tube body for preliminary water cooling and heat dissipation. A second sealing mechanism is provided at the first water sprinkling hole. The gas in the groove cavity can expand due to heat, pushing the block to move to the outside of the groove. The block moves to overlap the water outlet hole on it with the first water sprinkling hole. The water flow in the sprinkler can also flow out from the first water sprinkling hole on the side wall of the tube body. The spraying range is wider, which is conducive to heat dissipation. The temperature on different sides of the cabinet may be different, and the expansion degree of the gas in the corresponding side groove is different. The distance of controlling the movement of the block is different, so the degree of exposure of the first water sprinkling hole is also different. By controlling the water output of the first water sprinkling holes at different positions of different tube bodies, water sprinkling and heat dissipation can be targeted, and the cooling effect is better.

[0018] Furthermore, a heat absorbing material is provided on the side wall of the groove containing the thermally expanding and contracting gas.

[0019] The heat absorbing material is arranged to concentrate the heat and control the volume change of the gas in the groove due to thermal expansion and contraction.

[0020] Furthermore, the first watering hole and the second watering hole are both inclined from top to bottom and toward the outside of the tube body.

[0021] The watering holes are set at an angle to facilitate the outflow of liquid.

[0022] Furthermore, it also includes a water supply mechanism, which includes a water pump, a water supply system, a second elastic member, a placement plate, an automatic reset button and a non-automatic reset button;

[0023] The water pump is connected to the water supply system, and the water pump is connected to the water tank through a water supply pipe;

[0024] The second elastic member is arranged vertically, the placement plate is placed horizontally, one end of the second elastic member is fixedly connected to the top of the housing, and the other end is fixedly connected to the bottom of the placement plate, and the water tank is placed on the placement plate;

[0025] The automatic reset button is installed on the top of the housing and is located directly below the placement plate, and the placement plate can be against the automatic reset button;

[0026] The non-automatic reset button is installed on the shell through a frame. The non-automatic reset button is located directly above the water tank. The non-automatic reset button can be against the top of the water tank. The output end of the non-automatic reset button is connected to the control end of the water pump, and the output end of the automatic reset button is connected to the reset end of the non-automatic reset button.

[0027] When there is less water in the water tank, the compression degree of the second elastic member is low, and the second elastic member and the placement plate support the water tank so that the top of the water tank abuts against the non-automatic reset button. The non-automatic reset button outputs a control signal to the water pump, and the water pump starts to fill the water tank with water. As water flows into the water tank, the pressure on the placement plate and the second elastic member increases, and the second elastic member is gradually compressed until the placement plate abuts against the automatic reset button. The output end of the automatic reset button is connected to the reset end of the non-automatic reset button, and the non-automatic reset button is reset. Then, the non-automatic reset button no longer outputs a control signal to the water pump, and the water pump stops. There is no need to set up real-time monitoring equipment, which reduces energy consumption.

[0028] Furthermore, a drain port is provided on the outer wall of the shell near the bottom thereof, and a third sealing mechanism identical to the second sealing mechanism is provided at the drain port.

[0029] A drain port is provided. When the temperature at the drain port rises, the third sealing mechanism opens and can be used as a vent. When water is filled into the shell, the water flows through the drain port to cool it down, and the third sealing mechanism can close the drain port again. If the water flow is overheated due to heat exchange, the third sealing mechanism opens again to discharge the hot water, and the water tank flows cooling water into the shell again.

[0030] Furthermore, the outer wall of the cabinet is provided with heat conducting material.

[0031] It speeds up the heat dissipation from the inside of the cabinet to the outside, which is beneficial to heat dissipation.

[0032] Furthermore, a heat insulation layer is provided on the outer wall of the water tank.

[0033] The heat-insulating layer can prevent the water tank from being heated by sunlight, thus facilitating its use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0039] The present invention discloses an energy-saving and heat-dissipating communication cabinet, such as Figure 1 As shown, it includes a cabinet 1 and a heat dissipation mechanism arranged outside the cabinet 1, and the cabinet 1 itself is sealed. The heat dissipation mechanism includes an outer shell 2, a water tank 3 and a sprinkler 4. The outer shell 2 is a solid frame structure. The cabinet 1 is placed in the outer shell 2 as a whole, and the outer shell 2 can be sealed. The outer wall of the cabinet 1 is provided with a heat-conducting material (such as a conventional heat-conducting sheet, heat-conducting silica gel, etc.) to accelerate the speed of heat dissipation from the inside of the cabinet 1 to the outside, which is beneficial to heat dissipation. The bottom of the cabinet 1 is fixedly connected to the inner bottom of the outer shell 2 (such as welding, bonding, integral forging connection, etc.), and there is a gap between the other side walls of the cabinet 1 and the outer shell 2.

[0040] The water tank 3 of the heat dissipation mechanism is installed on the outer top of the shell 2, and the sprinkler 4 is arranged on the inner top of the shell 2. A heat insulation layer is arranged on the outer wall of the water tank 3 to prevent the water tank 3 from being heated by sunlight. The heat insulation layer can be made of Dike aluminum foil heat insulation coil, thermal insulation paper, glass fiber wool board / felt, etc.

[0041] A vertical connection hole 5 is provided at the top of the housing 2 of the heat dissipation mechanism, and the connection block can be a square hole. The bottom of the water tank 3 is connected to the top of the connection hole 5, and the sprinkler 4 is connected to the bottom of the connection hole 5. A first sealing mechanism is provided in the connection hole 5, and the first sealing mechanism includes a transverse groove 6 and a baffle 7 for sealing the connection hole 5. The transverse groove 6 is provided on the left and right sides of the connection hole 5, and the two ends of the baffle 7 are respectively located in the transverse grooves 6 on both sides of the connection hole 5.

[0042] The baffle plate 7 of the first sealing mechanism is sealed and slidably connected to the transverse groove 6. The space formed by one end of the baffle plate 7 and the inner wall of the transverse groove 6 on one side of the connecting hole 5 contains a heat-expanding and cold-contracting gas (using a gas with a large expansion coefficient, such as CO2 gas, etc.). A first elastic member 9 is provided in the space between the baffle plate 7 and the transverse groove 6 containing the heat-expanding and cold-contracting gas. The first elastic member 9 can be a spring. One end of the spring is fixedly connected to the baffle plate 7 (such as welding or bonding), and the other end is fixedly connected to the inner wall of the transverse groove 6. The outer wall of the transverse groove 6 containing the heat-expanding and cold-contracting gas is provided with a heat-absorbing material (such as a rock wool board, etc.), which is conducive to concentrating heat and controlling the volume change of the heat-expanding and cold-contracting gas. The heat-absorbing material can absorb the heat of the sunlight irradiation outside the shell 2, which is used to control the water cooling of the water tank 3 and reduce the influence of the heat irradiation and heating of the sunlight on the cabinet 1. A through hole 8 is provided on the side of the baffle plate 7 close to the heat-expanding and cold-contracting gas. The through hole 8 is vertically arranged on the baffle plate 7. The through hole 8 can be placed in the transverse groove 6, or extend out of the transverse groove 6 and partially overlap or completely overlap with the connecting hole 5.

[0043] When the thermal expansion and contraction gas in the transverse groove 6 of the connecting hole 5 is heated, it can be known that the external sunlight temperature is too high or the temperature rises due to the heating of the equipment in the cabinet 1, and a cooling operation or a heat insulation operation is required. The thermal expansion and contraction gas expands and pushes the end of the baffle 7 out of the transverse groove 6, and the through hole 8 placed in the transverse groove 6 gradually overlaps with the connecting hole 5 as the baffle 7 moves. At this time, the connecting hole 5 is connected, and the water flow in the water tank 3 can enter the shell 2 through the connecting hole 5 to achieve automatic water cooling and heat dissipation. And according to the different temperatures received by the thermal expansion and contraction gas, its expansion degree is different, and the distance that pushes the baffle 7 to move is different, so that the area of ​​the through hole 8 overlapping with the connecting hole 5 is different, so as to control the water flow rate of the water tank 3 and avoid excessive water discharge and waste of water resources. When the temperature drops, the volume of the thermal expansion and contraction gas is restored, and the elastic force of the first elastic member 9 is conducive to the reset of the baffle 7 to block the connecting hole 5.

[0044] In a preferred embodiment of the present invention, the sprinkler 4 includes a tube body 10 with a sealed bottom, a plurality of first sprinkler holes 11 arranged on the tube wall of the tube body 10, and a plurality of second sprinkler holes 12 arranged at the bottom of the tube body 10. The sprinkler holes are evenly arranged on the circumference and bottom of the tube wall of the tube body 10. The first sprinkler holes 11 and the second sprinkler holes 12 are inclined from top to bottom and toward the outside of the tube body 10. The sprinkler holes are inclined to facilitate the outflow of liquid.

[0045] A second sealing mechanism is provided at the first watering hole 11, and the sealing mechanism includes a groove 14 and a block 13 for blocking the watering hole. The groove 14 is provided at the upper and lower sides of the first watering hole 11. The connection structure of the block 13 and the groove 14 is the same as the connection structure of the baffle 7 and the transverse groove 6 in the first sealing mechanism. The block 13 is provided with a water outlet on the side close to the thermal expansion and contraction gas in the corresponding groove 14. The water outlet is placed in the transverse groove 6 or overlaps with the corresponding first watering hole 11. The side wall of the groove 14 containing the thermal expansion and contraction gas is provided with a heat absorbing material, which is conducive to concentrating heat and controlling the volume change of the thermal expansion and contraction gas in the groove 14.

[0046] The water flowing through the connection hole 5 enters the tube body 10 and can fall into the housing 2 from the second water sprinkling hole 12 at the bottom of the tube body 10 for preliminary water cooling and heat dissipation. A second sealing mechanism is set at the first water sprinkling hole 11. Similar to the first sealing mechanism, the gas in the cavity of the groove 14 can expand due to heat, pushing the block 13 to move to the outside of the groove 14. The block 13 moves to overlap the water outlet hole on it with the first water sprinkling hole 11. The water flow in the sprinkler 4 can also flow out from the first water sprinkling hole 11 on the side wall of the tube body 10, and its spraying range is wider. After the volume of the gas that expands and contracts due to heat is restored, a negative pressure can be formed in the space, and at the same time, the block 13 itself is affected by gravity, driving the block 13 to reset. The temperatures on different sides of the cabinet 1 may be different, and the expansion degrees of the gas in the corresponding side grooves 14 are different, which controls the movement distance of the stopper 13 to be different, so that the degree of exposure of the first watering hole 11 is also different. By controlling the water output of the first watering holes 11 at different positions of different tube bodies 10, water can be sprayed in a targeted manner to dissipate heat, and the cooling effect is better.

[0047] In a preferred embodiment of the present invention, the energy-saving and heat-dissipating communication cabinet also includes a water supply mechanism. The water supply mechanism includes a water pump, a water supply system, a second elastic member 16, a placement plate 15, an automatic reset button 17, and a non-automatic reset button 18. The water pump is connected to the water supply system, and the water pump is connected to the water tank 3 through a water supply pipe. The water supply system can be groundwater or a tap water pipe. The second elastic member 16 is arranged vertically, and the placement plate 15 is placed horizontally. The second elastic member 16 can be a single or multiple springs. One end of the second elastic member 16 is welded to the top of the housing 2, and the other end is welded to the bottom of the placement plate 15. The water tank 3 is placed on the placement plate 15. A recessed groove can be provided on the placement plate 15 for placing the water tank 3. The bottom of the water tank 3 can be connected to the top of the connecting hole 5 through a water pipe.

[0048] The automatic reset button 17 of the water supply mechanism is fixedly installed (such as welding, bonding, etc.) on the top of the shell 2 and is located directly below the placement plate 15, and the placement plate 15 can be against the automatic reset button 17. The non-automatic reset button 18 is installed on the shell 2 through a frame, and the frame is welded to the shell 2, and the non-automatic reset button 18 can also be welded to the frame. The non-automatic reset button 18 is located directly above the water tank 3, and the non-automatic reset button 18 can be against the top of the water tank 3. The output end of the non-automatic reset button 18 is electrically connected to the control end of the water pump, and the output end of the automatic reset button 17 is electrically connected to the reset end of the non-automatic reset button 18. All electrical equipment required for this solution can be electrically connected to the power supply equipment of the cabinet 1 to ensure normal operation.

[0049] When there is less water in the water tank 3, the pressure of the water tank 3 on the placement plate 15 and the second elastic member 16 is relatively small, and the compression degree of the second elastic member 16 is relatively low. The distance between the second elastic member 16, the placement plate 15, the automatic reset button 17 and the non-automatic reset button 18 can be set as needed. The second elastic member 16 and the placement plate 15 support the water tank 3 so that the top of the water tank 3 abuts against the non-automatic reset button 18, and the non-automatic reset button 18 outputs a control signal to the water pump, and the water pump starts to fill the water flow into the water tank 3. As the water flows into the water tank 3, the pressure on the placement plate 15 and the second elastic member 16 increases, and the second elastic member 16 is gradually compressed until the placement plate 15 abuts against the automatic reset button 17, and the output end of the automatic reset button 17 is connected to the reset end of the non-automatic reset button 18, and the non-automatic reset button 18 is reset, then the non-automatic reset button 18 no longer outputs a control signal to the water pump, and the water pump stops.

[0050] More preferably, a drain port is provided on the outer wall of the housing 2 near the bottom thereof, and a third sealing mechanism (not shown in the figure) identical to the second sealing mechanism is provided at the drain port. The operation process of the third sealing mechanism is the same as that of the second sealing mechanism. When the temperature at the drain port rises and the third sealing mechanism is opened, it can be used as a vent. When water is filled into the housing 2, the water flows through the drain port to cool it down, and the third sealing mechanism can close the drain port again. If the water flow is overheated due to heat exchange, the third sealing mechanism is opened again to discharge the hot water, and the water tank 3 flows cooling water into the housing 2 again.
