Description

Technical Field

[0001] This utility model relates to the field of combustible gas detectors, specifically a combustible gas detector with good heat dissipation. Background Technology

[0002] Combustible gas detectors can accurately sense changes in airborne gases. Once the concentration of combustible gas exceeds a preset safety threshold, the alarm system is quickly triggered, emitting an audible and visual alarm to alert personnel to take timely countermeasures. These detectors are particularly crucial in flammable and explosive environments such as oil, chemical, and gas industries. Through real-time monitoring and early warning, they effectively prevent potential gas leaks, ensuring the safety of personnel and equipment. Furthermore, depending on the application scenario, combustible gas detectors can be categorized into three types: residential, commercial, and industrial. Residential combustible gas detectors are typically installed in homes to detect leaks of natural gas and liquefied petroleum gas. Commercial and industrial combustible gas detectors are generally explosion-proof products, suitable for large-scale industrial and commercial applications, such as oil, chemical, metallurgical, research, and large supermarkets.

[0003] The existing technology has the following problems:

[0004] Existing combustible gas detectors suffer from poor heat dissipation. These detectors generate heat during operation, and inadequate heat dissipation leads to increased internal temperatures. Excessive heat can affect the performance of the detector's electronic components and sensors, resulting in decreased sensitivity and even inaccurate detection of combustible gas concentrations. This performance degradation due to poor heat dissipation can cause false alarms or missed alarms. False alarms waste resources and cause unnecessary panic, while missed alarms may prevent the timely detection and handling of potential safety hazards. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a combustible gas detector with good heat dissipation, which solves the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned good heat dissipation effect, this utility model provides the following technical solution: a combustible gas detector with good heat dissipation effect, including a bottom shell, a top cover movably connected to one side of the bottom shell, a positioning sleeve provided on one side of the top cover, a positioning rod detachably provided on one side of the bottom shell, a positioning plate provided on the inner wall of the bottom shell, an electronic component board movably connected to one side of the positioning plate, a heat-conducting plate provided on one side of the electronic component board, a liquid cooling pipe fixedly connected to one side of the heat-conducting plate, a cold air radiator frame plate fixedly connected to one end of the liquid cooling pipe, cold air radiator blades provided on the inner wall of the cold air radiator frame plate, and a servo motor provided on one side of the heat-conducting plate.

[0009] The output end of the servo motor is fixedly connected to a rotating shaft via a coupling. The outer wall of the rotating shaft is equipped with heat dissipation fins and a dust removal brush plate. A mounting rod is mounted on the heat-conducting plate, and a nut is detachably mounted on the outer wall of the mounting rod. A heat dissipation mesh is provided on the back of the bottom shell. This design enables the combustible gas detector to have excellent heat dissipation capabilities. During operation, the detector absorbs and conducts heat, and utilizes a combination of water cooling and air cooling to quickly dissipate the heat, preventing heat buildup that could lead to malfunctions. This ensures the normal operation of the detector and meets user needs.

[0010] Preferably, the heat-conducting plate is connected to one side of the electronic component board and the other side of the servo motor on both sides, respectively. As a key heat dissipation component, the heat-conducting plate cleverly connects the electronic component board and the servo motor. During the operation of the combustible gas detector, the various electronic components on the electronic component board generate a large amount of heat, and the operation of the servo motor also generates heat. The heat-conducting plate, made of a highly efficient heat-conducting material, can effectively absorb and disperse this heat. Its two sides are tightly attached to the electronic component board and the servo motor, respectively, ensuring rapid heat transfer and laying a solid foundation for the subsequent heat dissipation process.

[0011] Preferably, one end of the liquid-cooled pipe is fixedly connected to one side of the heat-conducting plate, and the other end is connected to the radiator frame. As a crucial component of the heat dissipation system, the liquid-cooled pipe is designed with heat transfer and dissipation efficiency in mind. The fixed connection to the heat-conducting plate allows for rapid removal of heat absorbed by the plate, which is then circulated and cooled by the cooling liquid within the pipe. The other end connects to the radiator frame, transferring heat to the radiator blades in preparation for the air-cooling process. This combined liquid and air-cooling design significantly improves heat dissipation efficiency and ensures the stable operation of the combustible gas detector.

[0012] Preferably, several heat dissipation blades are provided, and these blades are equidistantly distributed in a ring around the center point of the rotating shaft. The heat dissipation blades are one of the key components of the air-cooled heat dissipation system. To maximize heat dissipation efficiency, the heat dissipation blades are designed as a plurality of blades, equidistantly distributed in a ring around the center point of the rotating shaft. This design not only ensures uniform airflow distribution but also improves the coverage area and heat dissipation efficiency of the air cooling system. When the servo motor drives the rotating shaft to rotate, the heat dissipation blades rotate accordingly, generating a strong airflow that rapidly cools the radiator blades, effectively reducing the internal temperature of the detector.

[0013] Preferably, the inner wall of the positioning sleeve is provided with an installation groove, and the outer wall of the positioning rod is provided with a threaded groove. The positioning rod is connected to the positioning sleeve through the installation groove and the threaded groove. The positioning sleeve and the positioning rod serve as connecting components between the bottom shell and the top cover, and their design fully considers the stability of the structure and the ease of disassembly. The inner wall of the positioning sleeve is provided with an installation groove, while the outer wall of the positioning rod is provided with a threaded groove. This design allows the positioning rod to be easily inserted into the installation groove of the positioning sleeve and secured by the threaded connection. When disassembly is required, the bottom shell and the top cover can be easily separated simply by loosening the positioning rod, providing great convenience for maintenance and component replacement.

[0014] Preferably, four mounting rods and eight nuts are provided. Each mounting rod and two nuts form a group, and the four groups of mounting rods and nuts are fixed to the four corners of the heat-conducting plate by threaded connections. The mounting rods and nuts serve as fixing components for the heat-conducting plate, and their design fully considers structural stability and ease of installation. By fixing the four mounting rods to the four corners of the heat-conducting plate and connecting them with eight nuts by thread, a tight fit and stable connection between the heat-conducting plate, the positioning plate, and the electronic component board are ensured. This design not only improves the overall stability of the heat dissipation system but also greatly facilitates subsequent maintenance and component replacement.

[0015] (III) Beneficial Effects

[0027] In this embodiment, the heat-conducting plate 7 is connected to one side of the electronic component board 6 and the other side of the servo motor 11, respectively. As a key heat dissipation component, the heat-conducting plate 7 cleverly connects the electronic component board 6 and the servo motor 11. During the operation of the combustible gas detector, the various electronic components on the electronic component board 6 generate a large amount of heat, and the operation of the servo motor 11 also generates heat.

Its two sides are tightly attached to the electronic component board 6 and the servo motor 11, respectively, ensuring rapid heat transfer and laying a solid foundation for the subsequent heat dissipation process.

[0028] In this embodiment, one end of the liquid-cooled pipe 8 is fixedly connected to one side of the heat-conducting plate 7, and the other end of the liquid-cooled pipe 8 is connected to the radiator frame plate 9. As an important component of the heat dissipation system, the liquid-cooled pipe 8 is designed with full consideration of heat transfer and dissipation efficiency. One end is fixedly connected to the heat-conducting plate 7, which can quickly remove the heat absorbed on the heat-conducting plate 7 and circulate the cooling liquid within the pipe for heat dissipation. The other end is connected to the radiator frame plate 9, transferring heat to the radiator blades 10 to prepare for the air-cooling process. This combination of liquid and air cooling design greatly improves heat dissipation efficiency and ensures the stable operation of the combustible gas detector.

[0029] In this embodiment, several heat dissipation blades 13 are provided, and these blades 13 are equidistantly distributed in a ring around the center point of the rotating shaft 12. The heat dissipation blades 13 are one of the key components of the air-cooled heat dissipation system. To maximize heat dissipation efficiency, the heat dissipation blades 13 are designed to be several and equidistantly distributed in a ring around the center point of the rotating shaft 12. This design not only ensures uniform airflow distribution but also improves the coverage area and heat dissipation efficiency of the air cooling system. When the servo motor 11 drives the rotating shaft 12 to rotate, the heat dissipation blades 13 rotate accordingly and generate strong airflow, which rapidly cools the radiator blades 10, effectively reducing the internal temperature of the detector.

The inner wall of the positioning sleeve 3 is provided with an installation groove, while the outer wall of the positioning rod 4 is provided with a threaded groove. This design allows the positioning rod 4 to be easily inserted into the installation groove of the positioning sleeve 3 and secured by the threaded connection. When disassembly is required, simply loosening the positioning rod 4 easily separates the bottom shell 1 from the top cover 2, providing great convenience for maintenance and component replacement.

The mounting rods 15 and nuts 16 serve as fixing components for the heat-conducting plate 7, and their design fully considers the stability of the structure and the convenience of installation.

This design not only improves the overall stability of the heat dissipation system but also provides great convenience for subsequent maintenance and component replacement.

[0033] In use, the electronic component board 6 and the heat-conducting plate 7 can be attached and installed on the positioning plate 5 using the mounting rod 15 and the nut 16. Then, the bottom shell 1 and the top cover 2 can be assembled and installed using the positioning rod 4 and the positioning sleeve 3. During the use of the detector, the heat-conducting plate 7 can absorb the heat generated by the electronic component board 6, and the heat is absorbed by the cooling liquid in the liquid cooling pipe 8 and guided to the cold radiator frame plate 9 and the cold radiator blades 10. The servo motor 11 can drive the rotating shaft 12 and the heat dissipation blades 13 to rotate and generate air force to cool the cold radiator blades 10. The heat is discharged through the heat dissipation mesh 17. The rotating shaft 12 can drive the dust removal brush plate 14 to move and continuously sweep the cold radiator blades 10 to remove dust, thus avoiding dust accumulation and affecting heat dissipation, thereby completing the work.
