Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electrical equipment heat dissipation, specifically, relate to a dustproof heat dissipation port of electrical automation equipment. BACKGROUND

[0002] The dustproof heat dissipation port of electrical automation equipment is to ensure that the equipment maintains good heat dissipation effect during use, and prevents dust and impurities from entering the equipment interior, thereby affecting the normal operation and service life of the equipment. It is an important component in the design of electrical equipment, especially in industrial environments, often facing challenges from external factors such as dust and moisture. Dustproof heat dissipation ports usually need to be equipped with dust screens or filter screens, which can effectively block external dust or particulate matter from entering the equipment interior, reducing dust accumulation inside the equipment and ensuring the cleanliness of internal components. The design of the heat dissipation port needs to ensure good air circulation to allow the heat generated inside the equipment to be dissipated in a timely manner and avoid overheating. Typically, the size, number, and location of the heat dissipation port need to be optimized based on factors such as equipment power and internal temperature. Larger heat dissipation area and reasonable ventilation design can effectively reduce the operating temperature of the equipment. The material of the heat dissipation port is usually a metal or plastic with good corrosion resistance, such as aluminum alloy, stainless steel, etc., to avoid corrosion affecting equipment performance in harsh environments.

[0003] The existing dustproof heat dissipation port is difficult to disassemble and is prone to blockage after long-term use. INVENTION CONTENTS

[0004] Therefore, the utility model provides a dustproof heat dissipation port of electrical automation equipment, which can solve the problem of difficult disassembly and blockage after long-term use of the existing dustproof heat dissipation port.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a dustproof heat dissipation port of electrical automation equipment, which comprises a mounting ring and a heat dissipation screen, the mounting ring comprises a fixed ring and a sealing ring, the heat dissipation screen comprises an inner heat dissipation screen and an outer heat dissipation screen, the fixed ring is fixed at the heat dissipation fan position of the electrical automation equipment, the sealing ring comprises two, and is fixed at the outer circle of the inner heat dissipation screen and the outer heat dissipation screen respectively, is used for fixing the inner heat dissipation screen and the outer heat dissipation screen on the fixed ring in sequence, so that the heat dissipation screen is convenient to disassemble and clean.

[0007] Based on the above technical solution, the dustproof heat dissipation port of electrical automation equipment of the utility model can also be improved as follows:

[0008] Among them, one side of the fixed ring is fixed on the electrical automation equipment through a bolt, and the other side is set in a groove, and the outer wall is provided with a thread.

[0009] Further, the size of the sealing ring corresponds to the size of the fixing ring, and the cross section is provided in an I-shaped type.

[0010] Further, the grid size of the inner heat dissipation net is smaller than the grid size of the outer heat dissipation net.

[0011] Further, the grid intersection point position of the inner heat dissipation net corresponds to and overlaps the grid intersection point and the grid center point position of the outer heat dissipation net.

[0012] Further, the inner wall of the sealing ring is provided with threads corresponding to the outer wall of the fixing ring, and the connection is achieved through the mutual cooperation between the threads.

[0013] Further, the fixing ring and the sealing ring are provided with clamping members on the connected surfaces, and the clamping members include clamping grooves and clamping protrusions, which are correspondingly arranged.

[0014] Further, the inner heat dissipation net, the outer heat dissipation net and the sealing ring are fixedly connected through a sealing strip, and the thickness of the sealing ring is 3 times the thickness of the inner heat dissipation net and the outer heat dissipation net.

[0015] Further, the inner wall of the sealing ring connected to the outer wall of the inner heat dissipation net is provided with threads away from the inner wall of the fixing ring, and the outer wall of the sealing ring connected to the outer wall of the outer heat dissipation net is provided with corresponding threads.

[0016] Further, the corresponding positions of the fixing ring and the sealing ring are provided with screw holes, and the connection between the fixing ring and the sealing ring is reinforced by inserting bolts.

[0017] Compared with the prior art, the dustproof and heat dissipation port of the electrical automation equipment has the following advantages: the fixing ring is used to fix the heat dissipation net assembly (the inner heat dissipation net and the outer heat dissipation net) at the heat dissipation fan position of the electrical automation equipment. Through the fixing ring, the heat dissipation net can be firmly installed in the heat dissipation port, preventing displacement or loosening during equipment operation, ensuring the stability and effect of the heat dissipation system. One side of the fixing ring is fixed on the electrical automation equipment by bolts, and the other side is provided with a groove and has threads, so that the heat dissipation net and other components can be firmly installed on the equipment and maintain a certain sealing property and stability.

[0018] The sealing ring is used to enhance the dustproof function of the device, preventing dust and foreign matter from entering the interior of the device through the heat dissipation port. The sealing ring fixes the inner heat dissipation net and the outer heat dissipation net on the fixing ring respectively, and forms a closed and stable structure, reducing the risk of dust entering the interior of the device. The sealing ring corresponds in size to the fixing ring, and its cross section is in the shape of an I-beam. This design enhances the sealing performance and avoids leakage during air flow.

[0019] The main function of the inner heat dissipation net is to block larger particles of dust from entering the interior of the device. At the same time, the grid size of the inner heat dissipation net is small, which helps to effectively intercept larger dust and impurities during air flow. The grid size of the inner heat dissipation net is smaller than that of the outer heat dissipation net, and it coincides with the corresponding staggered point position of the grid of the outer heat dissipation net. This design helps to improve the heat dissipation efficiency and reduce wind resistance, while enhancing the dustproof performance. The outer heat dissipation net cooperates with the inner heat dissipation net, and the grid size of the outer heat dissipation net is larger, but the staggered design with the inner heat dissipation net helps to optimize air flow and prevent excessive particles from blocking the heat dissipation system.

[0020] One side of the fixing ring is provided with a groove, and a thread is provided on the outer wall. Through this design, the fixing ring can be conveniently connected with the device body, making installation and disassembly more convenient and fast. The threaded connection further enhances the stability of the fixation, preventing loosening due to vibration or long-term use.

[0021] A clamping piece is arranged on the connecting surface between the fixing ring and the sealing ring, including a clamping groove and a clamping protrusion. Through the clamping design, the connection between the sealing ring and the fixing ring is more firm, and at the same time it is convenient to disassemble, which is convenient for cleaning and maintaining the heat dissipation net assembly.

[0022] The inner heat dissipation net, the outer heat dissipation net and the sealing ring are fixedly connected through a sealing strip, which can effectively improve the sealing performance and further prevent dust and other impurities from entering the interior of the device. The use of the sealing strip can also reduce the leakage in air flow and improve the heat dissipation efficiency. The thickness of the sealing ring is three times the thickness of the inner and outer heat dissipation nets, enhancing the compactness of the sealing and further improving the dustproof effect.

[0023] The outer wall of the sealing ring is provided with a thread at the connection with the inner heat dissipation net, and the outer wall of the outer heat dissipation net also has a corresponding thread cooperation with the inner wall of the sealing ring. Through this threaded connection, the combination of the inner and outer heat dissipation nets and the sealing ring is more firm, avoiding loosening or falling off of the heat dissipation net due to wind or vibration.

[0024] The retaining ring and sealing ring have corresponding screw holes for secure connection via bolt insertion. Bolted connections help ensure the retaining ring, sealing ring, and heat dissipation mesh remain stable and secure during high-intensity use, preventing components from loosening or falling off during operation and ensuring long-term stable operation of the equipment.
