Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 and Figure 4 An embodiment of this utility model provides: a compressor housing that is easy to maintain, including a base 1, a front cover 2 fixedly connected to the top right side of the base 1, a sound insulation bracket 12 fixedly connected to the top right side of the base 1, an air intake duct 11 fixedly connected to the top of the sound insulation bracket 12, a top cover 13 fixedly connected to the top of the front cover 2, a cooler 8 installed at the bottom of the top cover 13, an air guide shroud 9 fixedly connected to the bottom of the cooler 8, an axial fan 10 installed at the bottom of the air guide shroud 9, an organic cover 3 closely attached to the left side of the front cover 2, and a connecting mechanism provided on the front side of the front cover 2;

[0027] The axial fan 10 generates a high-speed axial airflow through the spiral motion of its blades. The air guide shroud 9 constrains the originally divergent radial airflow into a directional laminar flow parallel to the heat exchange surface of the cooler 8, allowing the airflow to vertically scour the cooler fins at a uniform speed. This reduces the local high-pressure zone and energy dissipation caused by turbulence. The chassis, through the axial fan 10 and the air guide shroud 9, forms a directional pressurized airflow control system. The intake duct 11 initially accelerates the intake air through cross-sectional contraction, while the axial fan 10 forms a local high-pressure zone at the front end of the cooler 8. This makes the pressure gradient distribution of the entire intake path more reasonable, thereby improving the intake efficiency of the air filter 14.

[0028] Reference Figure 2 The connecting mechanism includes a fixing member 4, which is fixedly connected to the front cover 2. A rotating shaft 6 is fixedly connected to the left side of the fixing member 4. A connecting plate 5 is rotatably connected to the surface of the rotating shaft 6. The connecting plate 5 is fixedly connected to the machine cover 3.

[0029] By integrating the fastener 4, the pivot 6, and the connecting plate 5 into the assembly gap between the front cover 2 and the chassis 3, only the flat surface of the chassis 3 is visible from the outside, avoiding the jamming problem caused by collisions and corrosion of traditional exposed hinges. When the chassis 3 is opened, the connecting plate 5 rotates along the pivot 6 to fit against the fastener 4, allowing maintenance personnel to directly view the entire interior area of ​​the chassis, thus improving the maintenance efficiency of the chassis.

[0030] Reference Figure 1 A second ventilation filter 19 is provided on the middle surface of the front cover 2. The second ventilation filter 19 is attached to the right side surface of the air intake duct 11. The second ventilation filter 19 serves as the primary filtration unit of the air intake system and forms a double-layer dustproof protection with the first ventilation filter 18 on the surface of the chassis. The second ventilation filter 19 is made of metal mesh. Through the attachment of the second ventilation filter 19 to the air intake duct 11, it can effectively block pollutants such as dust and fibers in the industrial environment and avoid valve plate wear or oil circuit blockage caused by impurities entering the chassis.

[0031] Reference Figure 2 The top cover 13 is equipped with a top heat dissipation mesh 15. The bottom surface of the top heat dissipation mesh 15 is in contact with the top surface of the cooler 8. The bottom of the top heat dissipation mesh 15 is completely in contact with the top plate of the cooler 8 through a thermally conductive strip. The heat of the refrigerant inside the cooler 8 is directly conducted to the top heat dissipation mesh 15 through the fins. Then, a dual heat dissipation path is formed by natural convection and the forced airflow of the axial fan 10, which improves the heat dissipation coefficient of the cooler 8 and effectively avoids the efficiency reduction of the compressor caused by overheating.

[0032] Reference Figure 4 An air filter 14 is rotatably connected to the rear side of the air intake duct 11. The air filter 14 is fixedly connected to the sound insulation bracket 12. The air filter 14 is fixed to the top of the sound insulation bracket 12 through an L-shaped bracket. The foam metal substrate and rubber vibration damping layer of the sound insulation bracket 12 can block the vibration of the compressor 20 from being transmitted to the air filter 14. At the same time, it can evenly distribute the weight of the filter to the base 1, avoiding the loosening of the filter element or deformation of the air duct due to long-term vibration.

[0033] Reference Figure 2 The base 1 has a back cover 17 fixedly connected to the top left side, and a side plate 16 fixedly connected to the back side of the back cover 17. The right side surface of the side plate 16 is in contact with the back side surface of the front cover 2. The ventilation filter 18 on the right side of the back cover 17, the side plate 16 and the front cover 2 forms a three-dimensional dustproof system. External airflow must be filtered through the filter before entering the chassis, thus effectively protecting the precision components inside the chassis.

[0034] Reference Figure 1 and Figure 3The front cover 2, side panel 16 and rear cover 17 are all provided with ventilation filter 18. Ventilation filter 18 is used to prevent external dust from entering the inside of the chassis. Ventilation filter 18, together with ventilation filter 2 19 and air filter 14, form a double dustproof network, which effectively blocks impurities such as sand, metal shavings and fibers in the industrial environment. Ventilation filter 18 is evenly distributed on three sides of the chassis, forming a ring-shaped air intake channel to avoid local negative pressure and airflow deviation caused by single-sided air intake.

[0035] Reference Figure 1 The control panel 7 is installed on the surface of the cover 3, and the compressor body 20 is set on the base 1. The control panel 7 is electrically connected to the compressor body 20. The control panel 7 is embedded in the outer surface of the cover 3. When the cover is opened, the panel rotates to the horizontal operating surface with the cover. The maintenance personnel can directly face the operating interface without bending over or going around, which makes it easier to maintain the compressor body 20.

[0036] Reference Figure 4 and Figure 5 The right side of the sound insulation bracket 12 is fitted with the left side surface of the front cover 2. A thick nitrile rubber sealing layer is embedded in the right side of the sound insulation bracket 12. The sealing layer can provide elastic support in the direction perpendicular to the fitting surface, thereby forming a continuous sound barrier structure, which effectively prevents the mechanical noise of the compressor host 20 from leaking through the gap between the sound insulation bracket 12 and the front cover 2.

[0037] Reference Figure 4 and Figure 5 The soundproof bracket 12 is made of foam metal. The top surface of the soundproof bracket 12 is covered with a rubber vibration isolation layer. The foam metal has a rich pore structure, which can effectively reduce the high-frequency vibration noise generated by the compressor during operation. The rubber vibration isolation layer has good elasticity and damping characteristics, which can absorb and buffer the vibration energy transmitted from the compressor, thereby effectively reducing the transmission of vibration to other parts of the soundproof bracket and the chassis, and reducing noise and structural fatigue caused by vibration.

[0038] Working principle: After the compressor body 20 starts, the airflow enters the intake air duct 11 through the second air filter 19. Since the intake air duct 11 is a gradually narrowing channel, it can guide the airflow to concentrate and accelerate into the air filter 14, thereby increasing the intake volume of the air filter 14 and improving the volumetric efficiency of the compressor main unit.

[0039] Since the intake duct 11 and the air filter 14 are both fixed on the top of the sound insulation bracket 12, and the sound insulation bracket 12 is fixed on the top of the base 1, and the sound insulation bracket 12 adopts a composite structure combining rubber vibration isolation layer and foam metal, it can attenuate the vibration generated when the compressor body 20 is running, thereby improving the intake efficiency of the compressor chassis while reducing the noise of the compressor body 20 during operation.

[0040] In terms of chassis heat dissipation, the axial fan 10 operates and the air guide shroud 9 directs the airflow generated by the axial fan 10 to the cooler 8, forming a forced convection heat dissipation path, improving the chassis cooling efficiency and avoiding performance degradation or shutdown failure due to overheating.

[0041] On the other hand, a fixing plate is installed on the top left side of the base 1, and a buckle is provided on the left side of the cover 3 to connect with the fixing plate. Since the connecting plate 5 is rotatably connected to the rotating shaft 6, and the connecting plate 5 is fixed on the front cover 2, the cover 3 can be rotated outward after being disconnected from the fixing plate. At the same time, since the connecting plate 5 is vertically fixed on the inner surface of the cover 3, the cover 3 can be rotated until its surface is in contact with the left side surface of the fixing part 4, so as to realize the large angle opening of the cover 3, thereby providing sufficient operating space for maintenance personnel and facilitating maintenance personnel to inspect the inside of the chassis.

[0042] In addition, since the fastener 4 is also fixed to the inner surface of the front cover 2, the connecting mechanism is hidden inside the chassis, thus avoiding the risk of the connecting mechanism being damaged by external impacts.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
