Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically, to a cylinder head reinforcing rib mounting structure for a piston compressor. Background Technology

[0002] Nowadays, the noise level of refrigerators has gradually become one of the evaluation criteria for consumers. As a key component of the refrigerator system, the compressor's quality is determined by the refrigerant gas flow rate, ensuring the freshness of chilled foods. During compressor operation, refrigerant gas, due to suction pressure, enters the silencer chamber from the suction pipe. The continuously drawn-in gas enters the cylinder from bottom to top, where it is compressed by the piston driven by the motor, and then discharged as high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power to the refrigeration system and realizing the cycle of suction, compression, exhaust, and expansion. Cylinder head seal failure is one of the common faults of piston-type refrigerator compressors, leading to a series of chain reactions that affect compressor performance, refrigeration system operation, and equipment lifespan.

[0003] Impact 1: Seal failure leads to cylinder pressure leakage, reducing compressor efficiency and resulting in weakened cooling capacity. Because sufficient pressure cannot be formed inside the cylinder, the air-fuel mixture cannot burn completely, causing the compressor to be underpowered and requiring longer operation time to reach the set temperature.

[0004] Impact 2: Poor sealing can lead to gas leaks, requiring the system to consume more than 25% extra energy to compensate for heat loss. The compressor continues to run to maintain cooling performance, directly increasing electricity costs.

[0005] Impact 3: Unstable operation and vibration may occur, and some cylinders may fail to work properly due to insufficient pressure. Therefore, we propose a cylinder head reinforcing rib installation structure for piston compressors. Utility Model Content

[0006] In view of the above-mentioned technical problems in related technologies, this utility model provides a cylinder head reinforcing rib mounting structure for a piston compressor, which can solve the above problems.

[0007] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: A cylinder head reinforcing rib mounting structure for a piston compressor includes a reinforcing rib block A fixed to the top of the cylinder head, reinforcing rib blocks B and C fixed to the left and right sides of the cylinder head, and reinforcing rib blocks E and F fixed to the bottom of the cylinder head. The bottom of the cylinder head has an integrally formed muffler mounting groove, and reinforcing rib blocks E and F are symmetrically arranged about the center line of the muffler mounting groove.

[0008] Furthermore, stiffeners A, B, C, E, and F are all rectangular parallelepipeds with dimensions of 8mm × 2mm × 2mm.

[0009] Furthermore, the top of each of the reinforcing ribs A, B, C, E, and F facing the cylinder head is provided with a sloping surface.

[0010] Furthermore, the tops of reinforcing ribs A, B, C, E, and F, and the side facing away from the inclined plane, are provided with arc surfaces.

[0011] Furthermore, the reinforcing rib A is aligned with the vertical center line of the cylinder head.

[0012] The beneficial effects of this utility model are as follows: The cylinder head of the device of this application is provided with rectangular reinforcing ribs on the front and sides. When the compressor is running at high speed, high temperature and high pressure gas enters the cylinder from bottom to top. The rectangular reinforcing ribs designed in the cylinder head can press the cylinder head tightly and fit it, playing a good sealing role and preventing gas leakage. The cylinder head reinforcing rib structure can increase the strength and rigidity of the compressor cylinder body. When the compressor is running, the pressure will cause a great impact and vibration to the cylinder body. The cylinder head reinforcing ribs can reduce vibration and impact, ensuring stable operation of the cylinder body. The cylinder head reinforcing ribs can prevent the compressor cylinder body from deforming under high temperature and high pressure, making the cylinder body more durable, which helps to improve the combustion efficiency and power output of the engine and extend its service life.

[0017] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] Example 1: As Figure 1-2 As shown, this utility model discloses a cylinder head reinforcing rib mounting structure for a piston compressor. This structure improves the overall performance of the cylinder head and compressor block by rationally setting reinforcing ribs at different positions on the cylinder head. The entire mounting structure mainly includes multiple cuboid reinforcing ribs fixed to different parts of the cylinder head, as well as an integrated muffler mounting groove on the cylinder head.

[0019] Specific settings of each component Cylinder head: As the basic load-bearing component of the entire mounting structure, the cylinder head has an integrally formed muffler mounting groove at its bottom end, which is used to install a muffler to reduce the noise generated during compressor operation.

[0020] Reinforcing ribs Reinforcing rib A1: Fixed to the top of the cylinder head and aligned with the vertical center line of the cylinder head. Reinforcing rib A1 is cuboid in shape, with dimensions of 8mm × 2mm × 2mm. A bevel is formed at the top of the side of reinforcing rib A1 facing the cylinder head, and an arc surface is formed at the top, away from the bevel. This design allows reinforcing rib A1 to fit better with the cylinder head and other components, reducing stress concentration.

[0021] Reinforcing ribs B2 and C3 are fixed to the left and right sides of the cylinder head, respectively. They are also rectangular parallelepipeds with the same dimensions as reinforcing rib A1: 8mm x 2mm x 2mm. A sloping surface is formed at the top of the side facing the cylinder head, with a rounded surface at the top facing away from the sloping surface. The symmetrical placement of reinforcing ribs B2 and C3 on both sides helps to balance the forces acting on the cylinder head in the lateral direction, enhancing structural stability.

[0022] Reinforcing ribs E4 and F5: Fixed to the bottom of the cylinder head, they are symmetrically arranged about the center line of the muffler mounting slot. Their shape and dimensions are the same as the aforementioned reinforcing ribs, both being cuboids with dimensions of 8mm × 2mm × 2mm. They also have a sloping surface at the top edge facing the cylinder head, with an arc surface at the top edge facing away from the sloping surface. This symmetrical arrangement not only ensures the balance of the cylinder head bottom structure but also works in conjunction with the muffler mounting slot, enhancing the strength of the cylinder head bottom without affecting muffler installation.

[0023] The reinforcing rib AE and cylinder head 6 are both fixed by welding.

[0024] When the compressor operates at high speed, high-temperature, high-pressure gas enters the cylinder from bottom to top. At this time, the reinforcing ribs installed on the top, sides, and bottom of the cylinder head, through their rational shape design and stable installation, can press the cylinder head tightly and ensure a close fit between the cylinder head and the cylinder body. The beveled and arc-shaped design of the reinforcing rib tops helps to better contact adjacent components under pressure, forming an effective sealing surface, thereby preventing gas leakage, ensuring stable internal pressure of the compressor, and improving compression efficiency. During compressor operation, pressure causes significant impact and vibration to the cylinder block. This invention incorporates multiple reinforcing ribs evenly distributed across different parts of the cylinder head, forming a stable reinforcing structure. These cuboid reinforcing ribs can withstand and disperse pressure, increasing the strength and rigidity of the compressor cylinder block. When pressure acts on the cylinder block, the reinforcing ribs reduce vibration and deformation, ensuring cylinder stability during operation and guaranteeing normal compressor operation, thus reducing the risk of component damage caused by vibration and impact. Compressors operate under high temperature and high pressure for extended periods, making the cylinder block prone to deformation. The reinforcing ribs on the cylinder head, especially the symmetrically positioned ribs E4 and F5 at the bottom relative to the muffler mounting slot, as well as the ribs on the top and sides, provide support and constraint to the cylinder head and block from different directions. They effectively resist thermal and mechanical stresses caused by high temperature and pressure, preventing cylinder block deformation under these conditions. Reduced cylinder block deformation extends its service life and contributes to improved engine combustion efficiency and power output. A stable cylinder block structure ensures proper combustion within the cylinder, allowing for complete fuel combustion and thus improving energy efficiency.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
