Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution cabinet with temperature regulation function. Background Technology

[0002] Distribution cabinets are the final stage equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the loads are relatively dispersed and there are fewer circuits, while motor control centers are used in situations where the loads are concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the previous stage power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] A search revealed Chinese patent CN217642313U, which discloses a power distribution cabinet with temperature regulation function. The cabinet includes a cabinet door hinged to its front wall, a first dustproof mesh embedded in one side wall, a fan box fixedly installed on the rear wall, a ventilation duct fixedly installed on the bottom inner side of the cabinet, a support box fixedly installed on the bottom inner side of the cabinet, and a heating plate fixedly installed on one inner wall of the support box. This temperature-regulating power distribution cabinet uses a motor to drive fan blades, causing airflow to carry away heat from bottom to top, thus rapidly lowering the temperature. The heating plate heats the air to prevent damage to electrical components from excessively low temperatures. A temperature sensor monitors temperature changes inside the cabinet in real time, and a controller adjusts the operation of the motor, heating plate, and audible and visual alarm. The audible and visual alarm promptly notifies staff if the temperature fails to decrease or rises for an extended period.

[0004] However, the above design still has shortcomings. The power distribution cabinet with temperature regulation function does not have a replaceable filter plate inside. When the fan blades rotate, dust in the air is easily blown into the power distribution cabinet, which makes the internal parts of the power distribution cabinet easy to be damaged and inconvenient to use.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a power distribution cabinet with temperature regulation function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a power distribution cabinet with temperature regulation function, comprising a cabinet body, with mounting boxes fixedly connected to both outer walls of the cabinet body, a cooling chamber inside the mounting box, and air inlets connected to each other on the two cooling chambers on opposite sides, a second threaded cap threadedly connected to the inner wall of the air inlet, a second vent opening through the surface of the second threaded cap, a second filter screen fixedly installed inside the second vent opening, an air pump installed on the top of the cabinet body, an air outlet pipe fixedly connected to the output end of the air pump, a first threaded cap threadedly installed at the opening of the air outlet pipe, a first vent opening through the surface of the first threaded cap, and a first filter screen fixedly installed inside the first vent opening.

[0008] As a further embodiment of this utility model: a semiconductor cooler is installed at the bottom of the interior of the cooling cavity, and a heat sink is installed at the bottom of the semiconductor cooler.

[0009] As a further embodiment of this utility model: each of the two cooling cavities has a connected air vent on one side that is close to each other, and the air vent is connected to the interior of the cabinet.

[0010] As a further embodiment of this utility model: an air suction pipe is installed at the top of the inside of the cabinet, and the air suction pipe is connected to the input end of the air pump through a pipe.

[0011] As a further embodiment of this utility model: a plurality of interconnected suction heads are fixedly provided at the bottom of the suction pipe, and a temperature sensor is installed on the right side of the suction pipe.

[0012] As a further embodiment of this utility model: support plates are fixedly connected to both sides of the air pump, and a triangular baffle is fixedly connected to the top of the support plates.

[0013] As a further embodiment of this utility model: the front end of the cabinet is rotatably provided with a cabinet door, and support blocks are fixedly connected to the four corners of the bottom of the cabinet.

[0014] This utility model has the following beneficial effects:

[0015] (1) Through the structural design of the first threaded cover, the air outlet pipe, the first filter screen, the first vent, the second threaded cover, the second filter screen, the second vent, and the air inlet, it is possible to facilitate the cleaning of the first filter screen or the second filter screen, thereby ensuring the filtration effect of the first filter screen or the second filter screen and improving the use effect. This solves the problem that the power distribution cabinet with temperature regulation function does not have a replaceable filter plate inside. When the fan blades rotate, dust in the air is easily blown into the power distribution cabinet, making the parts inside the power distribution cabinet easily damaged and inconvenient to use.

[0016] (2) Through the structural design of the air pump, suction pipe, temperature sensor, suction head, cooling chamber, air outlet and semiconductor cooler, the temperature inside the cabinet can be reduced quickly, thereby achieving the purpose of rapid heat dissipation.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-4 This utility model provides an embodiment of a power distribution cabinet with temperature regulation function, including a cabinet body 2. A cabinet door 6 is rotatably mounted on the front end of the cabinet body 2. Support blocks 7 are fixedly connected to the four corners of the bottom of the cabinet body 2. Mounting boxes 3 are fixedly connected to the outer walls of both sides of the cabinet body 2. The interior of the mounting boxes 3 is provided with cooling chambers 19. Two air inlets 18 are opened on the sides of the two cooling chambers 19 that are far apart from each other. A second threaded cover 15 is threadedly connected to the inner wall of the air inlet 18. The surface of the second threaded cover 15... A second vent 17 is provided through the cabinet 2. A second filter 16 is fixedly installed inside the second vent 17. An air pump 4 is installed on the top of the cabinet 2. Support plates 5 are fixedly connected to both sides of the air pump 4. A triangular baffle 1 is fixedly connected to the top of the support plate 5. An air outlet pipe 9 is fixedly connected to the output end of the air pump 4. A first threaded cap 8 is threaded at the opening of the air outlet pipe 9. A first vent 12 is provided through the surface of the first threaded cap 8. A first filter 11 is fixedly installed inside the first vent 12.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during use, the first filter 11 and the second filter 16 work together to effectively filter the air, preventing dust from entering the distribution cabinet with the airflow. Simultaneously, by rotating the first threaded cover 8 until it detaches from the air outlet 9, or by rotating the second threaded cover 15 until it detaches from the air inlet 18, the first or second threaded cover 8 can be cleaned. After cleaning, the first or second threaded cover 8 can be installed. This ease of disassembly and reassembly facilitates cleaning of the first or second filter 16, ensuring its filtration effect and improving overall performance. This solves the problem of distribution cabinets with temperature regulation lacking replaceable filters, where dust is easily blown into the cabinet by the fan blades, causing damage to internal parts and hindering operation.

[0029] A semiconductor cooler 21 is installed at the bottom of the interior of the cooling chamber 19. A heat sink 22 is installed at the bottom of the semiconductor cooler 21. Both cooling chambers 19 have interconnected air inlets 20 on their sides that are close to each other. The air inlets 20 are connected to the interior of the cabinet 2. An air suction pipe 10 is installed at the top of the interior of the cabinet 2. The air suction pipe 10 is connected to the input end of the air pump 4 through a pipe. Multiple interconnected air suction heads 14 are fixedly installed at the bottom of the air suction pipe 10. A temperature sensor 13 is installed on the right side of the air suction pipe 10.

[0030] Specifically, such as Figure 3 and Figure 4 As shown, during use, the temperature inside the cabinet can be monitored in real time by the semiconductor cooler 21. When the temperature inside the cabinet reaches a certain level, the signal is transmitted to the peripheral controller. The peripheral controller controls the air pump 4 and the semiconductor cooler 21 to start. The semiconductor cooler 21 can cool the air inside the cooling chamber 19. The suction force generated by the air pump 4 when it is working, together with the suction pipe 10 and the suction head 14, can extract the air from the cabinet. The cold air in the cooling chamber 19 enters the cabinet 2 through the air duct 20, thereby quickly reducing the temperature inside the cabinet and achieving the purpose of rapid heat dissipation.

[0031] Working Principle: In this application, the first filter 11 and the second filter 16 work together to effectively filter the air, preventing dust from entering the electrical cabinet with the airflow. Simultaneously, by rotating the first threaded cover 8 until it detaches from the air outlet 9, or by rotating the second threaded cover 15 until it detaches from the air inlet 18, the first or second threaded cover 8 can be cleaned. After cleaning, the first or second threaded cover 8 can be reinstalled. This ease of disassembly and reassembly facilitates the cleaning of the first filter 11 or the second filter 16. This ensures the filtration effect of the first filter 11 or the second filter 16, thereby improving the performance. Secondly, the temperature inside the cabinet can be monitored in real time by the semiconductor cooler 21. When the temperature inside the cabinet reaches a certain level, the signal is transmitted to the peripheral controller. The peripheral controller controls the air pump 4 and the semiconductor cooler 21 to start. The semiconductor cooler 21 can cool the air inside the cooling chamber 19. The suction force generated by the air pump 4 when it is working, together with the suction pipe 10 and the suction head 14, can extract the air from the cabinet. The cold air in the cooling chamber 19 enters the cabinet 2 through the air duct 20, thereby quickly reducing the temperature inside the cabinet and achieving the purpose of rapid heat dissipation.
