Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor protection mechanism. Background Art

[0002] In existing air compressor protection structures, traditional heat dissipation solutions typically rely on simple fans or natural cooling. These solutions typically consist of a fixed housing, basic cooling vents, and a cooling device, relying primarily on a single fan-guided airflow for heat dissipation. While these solutions provide some protection, their relatively simple structure fails to effectively dissipate heat from the equipment's high-temperature components.

[0003] However, this type of traditional heat dissipation structure has obvious shortcomings in actual use. First, due to the lack of effective heat conduction and diversion design between the heat dissipation device and the internal structure of the compressor, the heat dissipation efficiency is low, and the heat cannot be discharged quickly, which can easily cause the equipment temperature to be too high, affecting the normal operation of the air compressor. In addition, due to the lack of effective air guidance in the heat dissipation air hole design, the exhausted hot air is easy to flow back, thereby affecting the cooling effect. The single fan structure in the traditional solution is also difficult to ensure effective heat dissipation under high-load working conditions, and the service life of the equipment is therefore affected. In view of this, research and improvement are carried out on the existing problems, and an air compressor protection mechanism is provided to solve the current problems. The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Utility Model Content

[0004] The utility model aims to solve the technical problems existing in the prior art or related technologies.

[0005] The present invention relates to an air compressor protection mechanism, comprising a plunger compressor unit, a gas compression tank, and a piston compression cylinder fixed inside the plunger compressor unit. The present invention is characterized in that a heat dissipation protection assembly is fixedly mounted on the surface of the plunger compressor unit. The heat dissipation protection assembly comprises a housing, an axial fan blade, and an oil cooling box fixed inside the housing. The oil cooling box is provided with a guide tube connected to the piston compression cylinder on its surface, and a plurality of finned coils are also provided on its surface. A guide tube and a conical air tube are provided inside the housing, and the axial fan blade is rotatably mounted inside the guide tube. Heat dissipation holes and an air intake grille are respectively provided at the upper and lower ends of the housing. A fan motor for driving the axial fan blade is fixedly mounted inside the heat dissipation holes. The finned coils on both sides of the oil cooling box are arranged in a circular pattern and opposite the axial fan blade. By fixing the heat dissipation protection assembly to the surface of the plunger compressor unit, the heat dissipation protection assembly and the plunger compressor unit are integrated into one structure, improving overall stability, effectively protecting the internal structure of the plunger compressor unit, and enhancing the protective effect during operation of the air compressor.

[0006] In a preferred embodiment, the present invention can be further configured such that the piston compression cylinder and the finned coil are provided with a plurality of evenly distributed heat dissipation fins. This evenly distributed fin structure increases the cooling area, further enhancing heat dissipation and preventing equipment failure due to overheating of the piston compression cylinder.

[0007] In a preferred embodiment, the present invention can be further configured such that the top surface of the oil cooling radiator is provided with fins fixed to the inner side of the conical air duct, with the fins being arranged radially. By providing the fins arranged radially on the top surface of the oil cooling radiator, the present invention improves the smoothness of air flow, ensures more uniform airflow during the heat dissipation process, and further enhances heat dissipation efficiency.

[0008] In a preferred embodiment, the present invention can be further configured such that the exhaust direction of the axial fan blades is guided by an air intake grille and then discharged through the heat dissipation holes. The air intake grille is provided on the inner side of the plunger compressor unit, and a filter layer is provided on the inner side of the air intake grille. By providing a reasonable intake and exhaust structure, the present invention effectively guides the air flow, forms a stable airflow channel, prevents external impurities from entering the interior of the plunger compressor unit, and improves the air purification effect.

[0009] In a preferred embodiment, the present invention can be further configured such that the guide tube has a double-layered cavity structure, with the cavity within the piston compression cylinder communicating with the inner cavity of the oil cooling radiator via the guide tube. The oil cooling radiator and the guide tube are filled with refrigerant. This double-layered cavity structure allows the refrigerant to form a circulating cooling path between the piston compression cylinder and the oil cooling radiator, thereby reducing the temperature of the piston compression cylinder and maintaining efficient cooling operation of the equipment.

[0010] In a preferred embodiment, the present invention can be further configured such that a temperature sensor is provided on the top surface of the piston compression cylinder, and the output end of the temperature sensor is electrically connected to a thermostat, which is used to control the power of the fan motor. By combining the temperature sensor and thermostat, the present invention enables real-time monitoring of the piston compression cylinder temperature and automatic adjustment of the fan motor power, effectively ensuring stable operation of the device.

[0012] 1. In the present invention, by arranging a shell, shaft fan blades and an oil cooling heat sink in the heat dissipation protection assembly, the combined structure of the shaft fan blades and the oil cooling heat sink is utilized to accelerate the heat dissipation speed, effectively protect the internal structure of the compressor, and at the same time achieve a good heat dissipation effect, thereby extending the service life of the equipment.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0022] The following is combined with Figures 1-4 An air compressor protection mechanism provided by some embodiments of the present invention is described. Example 1

[0023] The present embodiment provides an air compressor protection mechanism, comprising a plunger compressor unit 100, a gas compression tank 200, and a piston compression cylinder 110 fixed to the inner side of the plunger compressor unit 100. A heat dissipation protection assembly 300 is fixedly mounted on the surface of the plunger compressor unit 100, and the heat dissipation protection assembly 300 comprises a shell 310, an axial fan blade 320, and an oil cooling heat sink 330 fixed to the inner side of the shell 310. The surface of the oil cooling heat sink 330 is provided with a guide tube 120 connected to the piston compression cylinder 110, and a plurality of finned coils 331 are evenly arranged on the surface of the oil cooling heat sink 330 to enhance the cooling effect. A guide tube 311 and a conical wind tube 312 are provided on the inner side of the shell 310, wherein the axial fan blade 320 is rotatably mounted on the inner side of the guide tube 311 through a bearing, and is driven to rotate by a fan motor 321. To facilitate air circulation, heat dissipation holes 313 and air intake grilles 314 are provided at the upper and lower ends of the housing 310. Heat dissipation holes 313 are used to exhaust hot air, while air intake grilles 314 allow cool air to flow in. This design allows air to flow upward through the cooling airflow generated by the shaft fan blades 320, effectively accelerating heat dissipation and ensuring a stable temperature within the plunger compressor unit 100.

[0024] In this embodiment, to further enhance heat dissipation, heat dissipation fins are evenly distributed across the surfaces of the piston compression cylinder 110 and the finned coil 331. This significantly increases the heat dissipation surface area and further optimizes cooling efficiency. Cooled air is discharged to the outside through the heat dissipation vents 313. During intake, the filter layer of the intake grille 314 blocks impurities from entering, protecting the internal structure. Example 2

[0025] This embodiment further improves the structure of embodiment 1 by adding a multi-layer guide structure to achieve a more stable cooling effect. Similar to embodiment 1, the utility model includes a plunger compressor unit 100, a gas compression tank 200, and a piston compression cylinder 110 fixed to the inside of the plunger compressor unit 100. A heat dissipation protection component 300 is fixedly installed on the surface of the plunger compressor unit 100, and the heat dissipation protection component 300 includes a shell 310, an axial fan blade 320, and an oil cooling heat sink 330 fixed to the inside of the shell 310. The guide tube 120 arranged on the surface of the oil cooling heat sink 330 is a double-layer sandwich structure, so that the internal sandwich cavity of the piston compression cylinder 110 is connected to the inner cavity of the oil cooling heat sink 330 through the guide tube 120, and refrigerant is added to the sandwich cavity to make the cooling effect more significant.

[0026] Furthermore, to improve airflow uniformity, radially arranged fins are installed on the top surface of the oil cooling radiator 330. These fins are fixed to the inside of the conical air cylinder 312 to stabilize air flow. Air is introduced through the air intake grille 314 and distributed through the guide tube 311 and conical air cylinder 312 to the finned coils 331 on both sides of the oil cooling radiator 330, thereby evenly cooling the piston compression cylinder 110. The axial fan blades 320, located inside the guide tube 311 and driven by the fan motor 321, form an air discharge channel in the heat dissipation holes 313, ensuring smoother exhaust of hot air.

[0027] This embodiment incorporates a temperature monitoring system. A temperature sensor is mounted on the top surface of the piston compression cylinder 110 to monitor temperature changes in real time. The sensor's output is electrically connected to a thermostat. The thermostat regulates the power of the fan motor 321, allowing the cooling fan to automatically adjust its speed based on actual temperature conditions, effectively ensuring stable operation and temperature control.
