Abstract
Description
Technical Field
[0001] This invention belongs to the field of power supply cabinet technology and relates to an energy-saving communication power supply cabinet. Background Technology
[0002] In the field of communications, there are numerous scenarios requiring power supply from cabinets. For example, wall-mounted power cabinets are frequently used in construction, maintenance, or locations where power supply is difficult to obtain, to meet the needs of rapid deployment. The communication power supply system is the heart of the communication system; a stable and reliable power supply system is crucial to ensuring the safe and reliable operation of the communication system.
[0003] Since power supply cabinets are mostly installed outdoors, they are exposed to sunlight, causing the cabinet and its internal equipment to heat up. Furthermore, the numerous power supply devices within the cabinet generate a significant amount of heat during operation. To dissipate heat, ventilation holes are typically created in the cabinet, utilizing simple heat convection to allow airflow to dissipate the internal heat. However, in humid and rainy environments like those in southern regions, the high humidity can easily corrode and short-circuit the internal telecommunications equipment, leading to a decrease in the equipment's lifespan and transmission quality. Installing air conditioners or other cooling devices directly inside the cabinet would consume a large amount of electricity. Summary of the Invention
[0004] The purpose of this invention is to provide an energy-saving communication power supply cabinet that can cool and dissipate heat from the cabinet, prevent dust and moisture in the air from contaminating the internal components of the cabinet, and reduce power consumption.
[0005] To achieve the above objectives, the basic solution of the present invention is as follows: an energy-saving communication power supply cabinet, including a cabinet body, the cabinet body including a cabinet side wall and a cabinet door, and a heat dissipation mechanism provided outside the cabinet side wall, the heat dissipation mechanism including a shell, a sealing ring and a piston cylinder;
[0006] The outer shell covers the cabinet body except for the cabinet door, and there is a gap between the cabinet body side wall and the outer shell. The top or bottom of the cabinet body is connected to the outer shell.
[0007] The sealing ring is fitted onto the side wall of the cabinet, and the sealing ring is slidably connected to the side wall of the cabinet and the corresponding inner wall of the outer shell.
[0008] The piston cylinder is located outside the outer casing. A piston plate is slidably connected inside the piston cylinder. The piston cylinder has a first side wall and a second side wall opposite to the piston plate. The first side wall is connected to the cabinet body. The second side wall is connected to the outer casing at the end away from the end connected to the cabinet body. Cooling gas is placed between the first side wall of the piston cylinder and the piston plate. Cooling liquid is placed between the second side wall of the piston cylinder and the piston plate. The piston plate is connected to a control mechanism that controls its linear reciprocating movement.
[0009] The working principle and beneficial effects of this basic solution are as follows: the outer shell covers all sides of the cabinet except for the doors, providing heat insulation without affecting the opening and closing of the cabinet doors. A sealing ring is placed in the gap between the outer shell and the cabinet, and this sealing ring can divide the gap into two areas. Due to the separating effect of the sealing ring, airflow and water cooling do not interfere with each other.
[0010] The piston cylinder has a gas-filled side connected to the cabinet, and the cabinet is connected to the top or bottom of the outer shell. Cooling gas can enter the cabinet to cool the components inside, and then be discharged into the gap between the outer shell and the cabinet to cool the outer shell and the side walls of the cabinet. Furthermore, the cooling gas remains inside the piston cylinder, preventing external moisture and dust from being brought into the cabinet, thus protecting the components inside.
[0011] The piston cylinder, with its internal coolant, is directly connected to the outer casing, allowing the coolant to enter and cool the casing and cabinet. A control mechanism moves the piston plate back and forth, pushing cooling gas into the cabinet or coolant into the gap between the casing and cabinet. Air cooling and water cooling can alternate, making operation simple. The energy consumption for the linear reciprocating motion of the control mechanism is far less than the energy required for an air conditioning system. Furthermore, both the coolant and cooling gas can be reused, saving energy.
[0012] Furthermore, the cabinet is provided with several partitions, which divide the cabinet into multiple areas. The partitions are provided with several connecting holes, and the first side wall of the piston cylinder is connected to multiple areas of the cabinet through multiple branch pipes.
[0013] The cabinet interior is divided into zones by partitions, facilitating the planning and installation of equipment. The piston cylinder simultaneously supplies cooling gas to all areas within the cabinet via branch pipes, accelerating cooling efficiency.
[0014] Furthermore, a sealing mechanism is provided at the connection between the branch pipe and the cabinet area, the sealing mechanism including a horizontal groove and a baffle for sealing the connection;
[0015] The transverse grooves are arranged on both sides of the connecting point. The two ends of the baffle are respectively located in the transverse grooves on both sides of the connecting point. The baffle and the transverse grooves are connected in a sealed sliding connection. The space formed by one end of the baffle and the inner wall of the transverse groove on one side of the connecting point contains a gas that expands and contracts with temperature. The side of the baffle near the gas that expands and contracts with temperature is provided with a through hole. The through hole can be placed in the transverse groove or coincide with the connecting point.
[0016] When heated, the gas within the transverse groove expands, pushing a baffle to the outside of the groove. This movement aligns the through-hole on the baffle with the connecting point, allowing cooling gas to enter the corresponding area of the cabinet from the connecting point. Since different areas of the cabinet may have different temperatures, the degree of gas expansion within the transverse groove at the connecting point in the corresponding area will vary. This, in turn, controls the distance the baffle moves, resulting in different overlap areas between the through-hole and the connecting point. Controlling the gas flow rate at the connecting points in different areas allows for targeted cooling and improved cooling performance.
[0017] Furthermore, the control mechanism includes a temperature sensor, a temperature comparator, and a rodless cylinder. The temperature sensor is installed on the top of the cabinet, and its output is connected to the first input of the temperature comparator. The second input of the temperature comparator is connected to a temperature threshold memory, and its output is connected to the control terminal of the rodless cylinder.
[0018] Because hot air rises, mounting the temperature sensor on the top of the cabinet facilitates the acquisition of the required temperature signal. Based on the acquired temperature signal, the temperature comparator determines whether the cabinet is overheating and controls the rodless cylinder to activate when needed, controlling the alternating operation of air cooling and water cooling.
[0019] Furthermore, the piston plate is provided with cooling fins, and the output terminal of the temperature comparator is connected to the control terminal of the cooling fins.
[0020] When the cooling liquid or cooling gas enters the outer casing or cabinet, completes heat exchange, and then flows back into the piston cylinder under the action of the piston plate, the cooling fins can cool the cooling liquid and cooling gas again to ensure the cooling effect.
[0021] Furthermore, a solar panel is installed on the top of the outer casing, and the output end of the solar panel is connected to the power supply end of the control mechanism.
[0022] Using solar panels to generate electricity is convenient.
[0023] Furthermore, the cooling gas is dry air, and the cooling liquid is water.
[0024] The materials are simple and easy to obtain and use.
[0025] Furthermore, the piston cylinder is installed underground.
[0026] The piston cylinder is located underground, which can insulate and cool the cooling liquid and cooling gas. The cooling liquid or cooling gas enters the outer shell or cabinet, completes the heat exchange, and then flows back into the piston cylinder under the action of the piston plate. The underground temperature is low, and the cooling liquid and cooling gas can exchange heat with the underground temperature to restore the initial cooling temperature. Attached Figure Description

[0033] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0034] This invention discloses an energy-saving communication power supply cabinet, such as... Figure 1 As shown, it includes a cabinet 1, which includes a side wall and a door. A heat dissipation mechanism is provided on the outside of the side wall of the cabinet 1. The heat dissipation mechanism includes a shell 2, a sealing ring 3, and a piston cylinder 4.
[0035] The outer shell 2 of the heat dissipation mechanism covers all sides of the cabinet 1 except for the cabinet door. For example, one side of the outer shell 2 may have an opening, and the edge of the opening is welded to the edge of the side where the cabinet door is located. The outer shell 2 can be cylindrical or rectangular. There is a gap 12 between the side wall of the cabinet 1 and the outer shell 2. The top or bottom of the cabinet 1 is connected to the outer shell 2, and the cabinet 1 can be placed directly on the inner bottom of the outer shell 2. A sealing ring 3 is fitted onto the side wall of the cabinet 1. For example, if the side wall of the cabinet 1 has a vertical groove, a slider is welded to the sealing ring 3. The slider slides in contact with the groove, and the side wall of the slider fits against the inner wall of the groove, achieving a sealed sliding motion. Figure 1 and Figure 2 As shown, the sidewall of the sealing ring 3 is respectively attached to the sidewall of the cabinet 1 and the inner wall of the corresponding outer shell 2, so that the sealing ring 3 is respectively sealed and slidably connected to the sidewall of the cabinet 1 and the inner wall of the corresponding outer shell 2. The outline of the sealing ring 3 is "U" shaped. The sealing ring 3 divides the gap 12 between the outer shell 2 and the cabinet 1 into two areas: a water-cooled area and an air-cooled area.
[0036] The piston cylinder 4 of the heat dissipation mechanism is located outside the outer casing 2. A piston plate 5 is slidably connected inside the piston cylinder 4. The piston cylinder 4 has a first side wall 6 and a second side wall 7 opposite to the piston plate 5. The first side wall 6 communicates with the interior of the cabinet 1, and the second side wall 7 communicates with the end of the outer casing 2 away from its communication with the interior of the cabinet 1. This connection can be made using water pipes or air pipes. For example, if the first side wall 6 communicates with the cabinet 1, and the bottom of the cabinet 1 communicates with the outer casing 2, then the second side wall 7 communicates with the top of the outer casing 2. Cooling gas is placed between the first side wall 6 of the piston cylinder 4 and the piston plate 5, and cooling liquid is placed between the second side wall 7 of the piston cylinder 4 and the piston plate 5. The piston plate 5 is connected to a control mechanism that controls its linear reciprocating movement. Preferably, the cooling gas is dry air, and the cooling liquid is water; the materials are simple, easy to obtain, and easy to use.
[0037] In the initial state, the piston plate 5 is located on the side of the piston cylinder 4 closest to the second side wall 7. The cooling liquid in the piston cylinder 4 is pushed by the piston plate 5 and enters all or most of it into the gap 12 between the outer shell 2 and the cabinet 1, achieving heat insulation and cooling of the cabinet 1. The cooling liquid enters the water-cooled area between the outer shell 2 and the cabinet 1, and the sealing ring 3 is pushed by the cooling liquid to move towards the side of the outer shell 2. The cooling liquid surrounds the outer wall of the cabinet 1, providing more comprehensive heat insulation and cooling.
[0038] If cabinet 1 overheats, the control mechanism activates, controlling piston plate 5 to reciprocate linearly within piston cylinder 4. Piston plate 5 first moves towards the side wall 6, pushing cooling gas into cabinet 1. The cooling gas first cools the components inside cabinet 1, then enters the air-cooled area between cabinet 1 and outer shell 2, cooling outer shell 2 and the side walls of cabinet 1. The gas entering the air-cooled area pushes sealing ring 3 away from the connection point 10 between cabinet 1 and outer shell 2. Sealing ring 3 pushes the cooling liquid back into piston cylinder 4. When the cooling liquid exits the water-cooled area, it carries away heat from the side walls of cabinet 1 and outer shell 2. Furthermore, the cooling liquid dissipates heat after exiting gap 12, ensuring that the next liquid entering gap 12 is also at a lower temperature.
[0039] When the control mechanism moves the piston plate 5 toward the second side wall 7, the piston plate 5 pushes the cooling liquid into the gap 12 between the outer shell 2 and the cabinet 1. The cooling liquid enters the water-cooled area and drives the sealing ring 3 to move toward the side where the connection 10 between the outer shell 2 and the cabinet 1 is located. The sealing ring 3 pushes the cooling gas in the gap 12 into the cabinet 1. The cooling gas then enters the piston cylinder 4 through the cabinet 1.
[0040] In a preferred embodiment of the present invention, the control mechanism includes a temperature sensor (such as PT100), a temperature comparator, and a rodless cylinder. The temperature sensor is mounted (e.g., glued, welded, etc.) on the top of the cabinet 1. The output terminal of the temperature sensor is electrically connected to the first input terminal of the temperature comparator. The second input terminal of the temperature comparator is electrically connected to a temperature threshold memory. The output terminal of the temperature comparator is electrically connected to the control terminal of the rodless cylinder. The rodless cylinder can be a magnetic couple rodless cylinder, with a magnetic ring mounted on the piston plate 5. The rodless cylinder drives the piston plate 5 to reciprocate through magnetic force.
[0041] A temperature sensor collects the temperature signal inside cabinet 1 and transmits it to the temperature sensor. A temperature comparator compares the collected temperature signal value with the threshold value stored in the temperature threshold memory to determine whether cabinet 1 is overheated. When the collected temperature signal value is greater than the temperature threshold, the temperature comparator outputs a control signal to the control terminal of the rodless cylinder, controlling the rodless cylinder to start.
[0042] In a preferred embodiment of the present invention, a heat insulation layer, such as Dike aluminum foil insulation roll, thermal insulation paper, or fiberglass wool board / felt, is wrapped around the piston cylinder 4 to reduce the influence of external environmental heat on the internal temperature of the piston cylinder 4. A cooling fin is provided on the piston plate 5, and the output terminal of the temperature comparator is electrically connected to the control terminal of the cooling fin. When the cooling liquid or cooling gas enters the outer casing 2 or cabinet 1 and then flows back into the piston cylinder 4 under the action of the piston plate 5, the cooling fin can cool the cooling liquid and cooling gas again, ensuring the cooling effect.
[0043] In another preferred embodiment, the piston cylinder 4 is installed underground, such as one meter underground. The piston cylinder 4 is placed underground, where the temperature is lower, which can insulate and cool the cooling liquid and cooling gas. During the process of the cooling liquid or cooling gas flowing out of the gap 12 and back into the piston cylinder 4, the cooling liquid and cooling gas can exchange heat with the underground temperature to restore their initial cooling temperature.
[0044] In a preferred embodiment of the present invention, the cabinet 1 is provided with several partitions, which divide the cabinet 1 into multiple areas. The partitions have several connection holes. The first sidewall 6 of the piston cylinder 4 is connected to multiple areas of the cabinet 1 via multiple branch pipes. Gas in each area can circulate through the connection holes, ensuring smooth gas flow and utilizing heat exchange. The piston cylinder 4 simultaneously introduces cooling gas into each area of the cabinet 1 through the branch pipes, accelerating the cooling efficiency.
[0045] More preferably, a sealing mechanism is provided at the connection point 10 between the branch pipe and the cabinet 1 area, such as... Figure 3 As shown, the sealing mechanism includes a transverse groove 11 and a baffle 8 for sealing the connection 10. The transverse groove 11 is located on both sides of the connection 10, and both ends of the baffle 8 are located within the transverse groove 11 on both sides of the connection 10, with the baffle 8 and the transverse groove 11 in a sealing sliding connection. The space formed by one end of the baffle 8 and the inner wall of the transverse groove 11 on one side of the connection 10 contains a gas that expands and contracts with temperature (using a gas with a high expansion coefficient, such as CO2 gas). The side of the baffle 8 near the gas that expands and contracts with temperature has a through hole 9, which can be placed within the transverse groove 11 or overlap with the connection 10. In the initial state, the baffle 8 can be set to partially block the connection, and the through hole 9 partially overlaps with the connection hole.
[0046] The gas within the transverse groove 11 expands when heated, pushing the baffle 8 to move outwards. The baffle 8 then aligns its through-hole 9 with the connecting point 10, allowing cooling gas to enter the corresponding area of the cabinet 1 from the connecting point 10. Since different areas of the cabinet 1 may have different temperatures, the degree of gas expansion within the transverse groove 11 at the corresponding connecting point 10 varies. This, in turn, controls the movement distance of the baffle 8, resulting in different overlap areas between the through-hole 9 and the connecting point 10. Controlling the gas flow rate at the connecting points 10 in different areas allows for targeted cooling and better temperature reduction. When the temperature decreases, the volume of the thermally expanded gas returns to its original state, creating a negative pressure within the corresponding transverse groove 11, which can reset the baffle 8. Alternatively, a spring can be installed in the transverse groove 11 without gas, using the spring's compression force to reset the baffle 8.
[0047] In a preferred embodiment of the present invention, a solar panel (not shown in the figure) is mounted on the top of the outer casing 2. The solar panel can be riveted or screwed to the top of the outer casing 2 using a frame or other structure. The output end of the solar panel is electrically connected to the power supply end of the control mechanism. Using the solar panel to provide electrical energy is convenient for use.
