Description

Technical Field

[0001] This utility model relates to the field of air compressor cooler technology, and in particular to a cooler air chamber for uniform cooling. Background Technology

[0002] During operation, an air compressor needs to compress air and store it in a tank. Due to the high pressure, a significant amount of heat is generated. If the air is not cooled in time, overheating can occur, posing a safety hazard. An air compressor cooler is used to cool the air, ensuring it can operate continuously.

[0003] Chinese utility model patent CN217818276U discloses an air chamber for an air compressor cooler, including a cooling air chamber assembly. The assembly comprises multiple cooling pipes, each connected to a tube sheet at both ends. Each cooling pipe includes a straight pipe section, with corrugated pipe sections formed at both ends. A connector pipe section is formed at the end of each corrugated pipe section for connection to the tube sheet. A turbulent mixing element is provided within the straight pipe section to drive the gas passing through it to mix from the outside in. In this invention, when the cooling pipes experience thermal expansion and contraction leading to linear expansion and contraction, the deformation of the two corrugated pipe sections near the connector pipe section can compensate for the normal linear expansion and contraction of the cooling pipes, thereby reducing the damage to the connection between the connector pipe section and the tube sheet caused by linear deformation and improving the stability of the connection between the cooling pipes and the tube sheet.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: The aforementioned device only mixes the gas flowing through the cooling pipe by multiple turbulent mixing elements distributed at equal intervals on the inner wall of the cooling pipe. In actual use, when the gas flows through the cooling pipe rapidly, the gas with a higher temperature in the middle of the straight pipe section is prone to forming an air wall, which blocks the low-temperature gas flowing into the cooling pipe through the turbulent mixing elements. At this time, the gas adhering to the pipe wall of the straight pipe section is difficult to move to the middle of the straight pipe section, resulting in poor cooling effect. Utility Model Content

[0005] To solve the above problems, this utility model provides a cooler air chamber with uniform cooling.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a uniformly cooled cooler air chamber, including a cooler shell, two end caps respectively installed at both ends of the cooler shell, two tube plates symmetrically fixed at both ends of the inner wall of the cooler shell, and a plurality of cooling pipes jointly installed on the two tube plates. The cooling pipe includes two joint pipe sections respectively installed on the two tube plates, two corrugated pipe sections respectively connected to the two joint pipe sections, and a straight pipe section jointly installed on the two corrugated pipe sections. A plurality of turbulent mixing components are provided on the inner wall of the straight pipe section, and a plurality of mixing components for mixing turbulence are provided on the inner wall of the straight pipe section.

[0007] By adopting the above technical solution, when the air compressor is turned on, it easily generates a large amount of heat, requiring the operator to turn on the cooler to cool it down. At this time, the sidewalls of the multiple cooling pipes maintain a low temperature under the action of the coolant, thus keeping the gas temperature close to the inner wall of the cooling pipes low. When the gas passes rapidly through the cooling pipes, the air in the middle of the straight pipe section directly impacts the mixing assembly, causing it to disperse outwards under the action of the mixing assembly. This allows the hotter air to directly impact the cooler inner wall of the straight pipe section, further dissipating heat from the hotter air and improving the cooling effect of the cooling pipes.

[0008] Furthermore, the hybrid assembly includes two symmetrically fixed rods on the inner wall of the straight pipe section and a cylindrical block jointly mounted on the two fixed rods close to each other on their side walls.

[0009] Furthermore, the cylindrical block includes a first fixing block that is jointly mounted on the side walls of the two fixing rods close to each other, and a second fixing block that is fixed to the side wall of the first fixing block.

[0010] Furthermore, a conical surface is formed on the side wall of the second fixing block away from the first fixing block.

[0011] By adopting the above technical solution, when gas rapidly passes through the straight pipe section, the gas adhering closely to the inner wall of the straight pipe section impacts the inner wall of the turbulent mixing component. This causes the lower-temperature gas to move towards the center of the straight pipe section under the action of the turbulent mixing component, thus mixing the lower-temperature gas with the higher-temperature gas, thereby improving the cooling effect of the cooling pipe. Furthermore, when the air in the center of the straight pipe section comes into contact with the cylindrical block, the higher-temperature gas directly impacts the conical surface, causing the higher-temperature gas to dissipate outwards under the action of the conical surface. This increases the probability of the higher-temperature air coming into contact with the inner wall of the straight pipe section, further improving the cooling effect of the cooling pipe.

[0012] Furthermore, multiple ventilation holes are provided on the side wall of the fixing rod.

[0013] By adopting the above technical solution, the difficulty of gas passing through the fixed rod is reduced, which in turn reduces the difficulty of gas closely attached to the inner wall of the cooling pipe passing through the fixed rod, thereby improving the user experience of the device.

[0014] Furthermore, multiple blocking rings are provided on the inner wall of the straight pipe section.

[0015] Furthermore, the inner wall of the blocking ring is provided with multiple connecting holes.

[0016] By adopting the above technical solution, when the gas adhering to the inner wall of the cooling pipe passes through the baffle ring, the gas adhering to the inner wall of the cooling pipe is discharged through the connecting hole under the action of the outer wall of the baffle ring. This causes the gas adhering to the inner wall of the cooling pipe to collide with the gas in the middle of the straight pipe section, thereby increasing the probability of gas mixing and thus improving the cooling effect of the cooling pipe.

[0017] Furthermore, the cylindrical block is made of oxygen-free copper.

[0018] Furthermore, the cross-section of the fixing rod is circular.

[0019] Furthermore, the diameter of the fixing rod is 1 mm.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when the air compressor is turned on, it easily generates a large amount of heat, requiring the operator to turn on the cooler to cool it. At this time, the sidewalls of the multiple cooling pipes maintain a low temperature under the action of the coolant, thus keeping the gas temperature close to the inner wall of the cooling pipes low. When the gas passes rapidly through the cooling pipes, the air in the middle of the straight pipe section directly impacts the mixing assembly, causing the air in the middle of the straight pipe section to disperse outwards under the action of the mixing assembly. This allows the higher-temperature air to directly impact the lower-temperature inner wall of the straight pipe section, thus allowing the inner wall of the straight pipe section to dissipate heat from the higher-temperature air, thereby improving the cooling effect of the cooling pipes.

[0022] 2. In this application, when gas rapidly passes through the straight pipe section, the gas adhering closely to the inner wall of the straight pipe section impacts the inner wall of the turbulent mixing element. This causes the lower-temperature gas to move towards the center of the straight pipe section under the action of the turbulent mixing element, thereby mixing the lower-temperature gas with the higher-temperature gas and improving the cooling effect of the cooling pipe. Furthermore, when the air in the center of the straight pipe section comes into contact with the cylindrical block, the higher-temperature gas directly impacts the conical surface, causing the higher-temperature gas to disperse outwards under the action of the conical surface. This increases the probability of the higher-temperature air coming into contact with the inner wall of the straight pipe section, further improving the cooling effect of the cooling pipe.

[0023] 3. In this application, when the gas adhering to the inner wall of the cooling pipe passes through the baffle ring, the gas adhering to the inner wall of the cooling pipe is discharged through the connecting hole under the action of the outer wall of the baffle ring, thereby causing the gas adhering to the inner wall of the cooling pipe to collide with the gas in the middle of the straight pipe section, thereby increasing the probability of gas mixing and thus improving the cooling effect of the cooling pipe.

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figure 1-7As shown in the embodiment of this application, a uniformly cooled cooler air chamber is disclosed, including a cooler shell 1, a head cover 11, a tube sheet 2, a cooling pipe 3, a turbulent mixing component 4, a mixing assembly 5, and a baffle ring 7. Two head covers 11 are provided and are respectively installed at both ends of the cooler shell 1. The tube sheet 2 is a circular plate structure, and two tube sheets 2 are provided and symmetrically fixed at both ends of the inner wall of the cooler shell 1.

[0034] Multiple cooling pipes 3 are provided and are installed together on two tube sheets 2. The cooling pipes 3 include connector pipe sections 31, corrugated pipe sections 32, and straight pipe sections 33. There are two connector pipe sections 31, which are installed on the two tube sheets 2 respectively. There are two corrugated pipe sections 32, which are connected to the two connector pipe sections 31 respectively. The straight pipe sections 33 are circular tube structures and are installed together on the two corrugated pipe sections 32. Multiple turbulence mixing components 4 are provided and are evenly distributed on the inner wall of the straight pipe sections 33.

[0035] Multiple mixing components 5 are arranged sequentially on the inner wall of the straight pipe section 33 for mixing turbulent flow. The mixing component 5 includes fixed rods 51 and cylindrical blocks 52. The fixed rods 51 are cylindrical rod-shaped structures, and multiple fixed rods 51 are symmetrically fixed in pairs to the inner wall of the straight pipe section 33. The diameter of each fixed rod 51 is 1 mm. Cylindrical blocks 52 are jointly installed on the sidewalls of two fixed rods 51 that are close to each other. Each cylindrical block 52 includes a first fixed block 521 and a second fixed block 522. The first fixed block 521 is a cylindrical block structure and is jointly installed on the sidewalls of two fixed rods 51 that are close to each other. The second fixed block 522 is a cylindrical block structure, fixed to the sidewall of the first fixed block 521, and a conical surface 53 is formed on the sidewall of the second fixed block 522 away from the first fixed block 521.

[0036] When gas rapidly passes through the straight pipe section 33, the gas adhering closely to the inner wall of the straight pipe section 33 impacts the inner wall of the turbulent mixing component 4. This causes the lower-temperature gas to move towards the center of the straight pipe section 33 under the influence of the turbulent mixing component 4, resulting in mixing between the lower-temperature and higher-temperature gases, thus improving the cooling effect of the cooling pipe 3. Furthermore, when the air in the center of the straight pipe section 33 comes into contact with the cylindrical block 52, the higher-temperature gas directly impacts the conical surface 53. This causes the higher-temperature gas to disperse outwards under the influence of the conical surface 53, increasing the probability of the higher-temperature air contacting the inner wall of the straight pipe section 33, further enhancing the cooling effect of the cooling pipe 3.

[0037] To improve the user experience of the device, multiple vent holes 6 are provided on the side wall of the fixing rod 51. This design reduces the difficulty for gas to pass through the fixing rod 51, thereby reducing the difficulty for gas that is close to the inner wall of the cooling pipe 3 to pass through the fixing rod 51, and thus improving the user experience of the device.

[0038] Multiple baffle rings 7 are arranged sequentially on the inner wall of the straight pipe section 33, and multiple connecting holes 8 are opened on the inner wall of the baffle rings 7. When the gas adhering to the inner wall of the cooling pipe 3 passes through the baffle rings 7, the gas adhering to the inner wall of the cooling pipe 3 is discharged through the connecting holes 8 under the action of the outer wall of the baffle rings 7. This causes the gas adhering to the inner wall of the cooling pipe 3 to collide with the gas in the middle of the straight pipe section 33, thereby increasing the probability of gas mixing and thus improving the cooling effect of the cooling pipe 3.

[0039] To extend the service life of cylindrical block 52, cylindrical block 52 is made of oxygen-free copper.

[0040] The principle of the uniformly cooled air chamber in this embodiment is as follows: When the operator turns on the air compressor, the air compressor easily generates a lot of heat, and the operator needs to turn on the cooler to cool the air compressor. At this time, the side walls of the multiple cooling pipes 3 maintain a low temperature under the action of the coolant, thus keeping the gas temperature close to the inner wall of the cooling pipes 3 low. When the gas passes through the cooling pipes 3 quickly, the air in the middle of the straight pipe section 33 directly impacts the mixing component 5, causing the air in the middle of the straight pipe section 33 to dissipate to the surroundings under the action of the mixing component 5. This allows the higher temperature air to directly impact the lower temperature inner wall of the straight pipe section 33, thereby allowing the inner wall of the straight pipe section 33 to dissipate heat from the higher temperature air, thus improving the cooling effect of the cooling pipes 3.

All technical solutions falling within the scope of this utility model's concept are protected.
