Description

Technical Field

[0001] The utility model relates to the field of air compressors, in particular to a radiator for an air compressor. Background Art

[0002] During the compression process of air in the air compressor, the heat generated by the work performed on the air and the mechanical friction during operation is transferred to the compressed air through heat exchange, causing the temperature of the air to rise as it passes through the air compressor. In most compressed air applications, there are strict requirements for the compressed air outlet temperature of the air compressor. If the temperature is too high, it will affect the subsequent compressed air use process. Utility Model Content

[0003] The present application provides an air compressor radiator, which has the effect of reducing the outlet temperature of compressed air.

[0004] The air compressor radiator provided in this application adopts the following technical solution:

[0005] A radiator for an air compressor is characterized in that it includes a casing, an air inlet and an air outlet are provided on the casing, an air flow duct and a water cooling structure are arranged inside the casing; the two ends of the air flow duct are respectively connected to the air inlet and the air outlet, the water cooling structure is used to cool the compressed air in the air flow duct, and multiple heat sinks are installed on the outside of the casing.

[0006] Through the above technical solution, a water-cooling structure is adopted as the main heat dissipation method, supplemented by heat sinks on the outside of the casing for auxiliary heat dissipation, which can quickly reduce the temperature of the compressed air in the air flow duct and avoid affecting the subsequent compressed air usage process.

[0007] Preferably, the air inlet and the air outlet are both arranged at the lower end of the casing and close to the front face; the air flow duct is U-shaped and is divided into a curved section and two straight sections; the water cooling structure is arranged at the upper end of the casing, and the multiple heat sinks are arranged between the lower end of the casing and the water cooling structure.

[0008] Through the above technical solution, the air inlet and outlet are set at the lower end, and the water cooling structure is set at the upper end of the casing, utilizing the natural convection principle of hot air rising and cold air falling to ensure the stability of compressed air circulation; multiple heat sinks are set between the lower end of the casing and the water cooling structure to fully utilize the space of the casing and maximize the heat dissipation area; and the water cooling structure further cools the air after passing through the U-shaped airflow duct to ensure that the outlet temperature of the compressed air meets the requirements.

[0009] Preferably, the water cooling structure includes multiple cooling water pipes and two fixed plates, and water inlet holes and water outlet holes are respectively opened on the left and right sides of the upper end of the casing along the horizontal straight direction. The two fixed plates are respectively threadedly connected to the water inlet holes and the water outlet holes, and multiple mounting ports are opened circumferentially; the multiple mounting ports correspond to multiple cooling water pipes, and the two ends of the cooling water pipes are respectively connected to the mounting ports corresponding to the fixed plates on both sides; the middle end of the cooling water pipe is wrapped around the outer circumference of the bent section of the air flow pipe.

[0010] Through the above technical solution, the cooling water circulates in the pipeline, which can effectively absorb and take away the heat generated by the bent pipe section, thereby significantly reducing the temperature of the air flow pipeline and improving the overall heat dissipation efficiency; since the fixed plate is connected to the water inlet and outlet holes by threads, it can be easily disassembled by the operator when replacement is required.

[0011] Preferably, a plurality of gaskets are installed in the air flow duct, and the plurality of gaskets are sequentially arranged on a straight line section between the air inlet and the water cooling structure.

[0012] Through the above technical solution, when the compressed air flows from the air inlet to the cooling structure in the air flow duct, it collides with the annular gasket every time it passes through it. The collision causes the flow direction of part of the compressed air to change, thereby slowing down the flow rate of the compressed air and giving it more time to cool down.

[0013] Preferably, a cylindrical plug is installed in the air flow duct, and the cylindrical plug is located on the straight section between the water cooling structure and the air outlet; the cylindrical plug is vertically opened with a through hole in the up and down directions, and both ends of the through hole are chamfered.

[0014] Through the above technical solution, compressed air flows from a large-diameter pipe into a small-diameter pipe. In this process, due to the reduction in the cross-sectional area of the pipe, the gas will be hindered by the pipe wall during the contraction process, and part of the kinetic energy will be converted into pressure energy, resulting in an increase in gas pressure, reducing the situation where the compressed air pressure decreases after cooling. Since the compressed air will pass through the heat sink again, the little heat generated will be dissipated to avoid affecting the outlet temperature.

[0015] Preferably, two straight sections of the airflow duct are respectively provided with two pressure relief holes, the two pressure relief holes pass through the casing and are located at the front end surface of the casing.

[0016] Through the above technical solution, the pressure relief hole is usually blocked by a pressure plug. The design of the pressure relief hole can directly release compressed air when the internal pressure of the air compressor rises abnormally, avoiding pipeline rupture due to overpressure or other safety accidents.

[0017] Preferably, mounting seats are respectively installed at the air inlet and the air outlet, and threaded holes that completely penetrate the casing are respectively opened at the left and right ends of the mounting seats, and the threaded holes are located on the left and right sides of the straight section of the airflow duct.

[0018] Through the above technical solution, the design of the mounting base provides a stable support for the air inlet and the air outlet when installed on the air compressor, ensuring that the interface will not loosen or leak under high pressure or high flow rate air flow conditions.

[0019] The technical effects of this utility model are mainly reflected in the following aspects:

[0020] 1. This utility model adopts a water-cooling structure as the main heat dissipation method, supplemented by heat sinks on the outside of the casing for auxiliary heat dissipation, which can quickly reduce the temperature of the compressed air in the air flow pipeline and avoid affecting the subsequent compressed air use process;

[0021] 2. In the process of compressed air flowing from the air inlet to the cooling structure, the compressed air collides with the annular gasket every time it passes through it. The collision changes the direction of part of the compressed air flow, thereby slowing down the flow rate of the compressed air and giving it more time to cool down.

[0022] 3. The utility model uses the design of a cylindrical plug to allow compressed air to flow from a large-diameter pipe into a small-diameter pipe. In this process, due to the reduction in the cross-sectional area of the pipe, the gas will be hindered by the pipe wall during the contraction process, and part of the kinetic energy will be converted into pressure energy, resulting in an increase in gas pressure, thereby reducing the situation where the compressed air pressure decreases after cooling. Since the compressed air will pass through the heat sink again, the little heat generated will be dissipated to avoid affecting the outlet temperature. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-3 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0028] The present application discloses an air compressor radiator:

[0029] Reference Figure 1-2 An air compressor radiator includes a housing 1 having an air inlet 11 and an air outlet 12 formed therein. An airflow duct 2 and a water-cooling structure 3 are fixed within the housing 1. The airflow duct 2 is connected to the air inlet 11 and the air outlet 12 at both ends. The water-cooling structure 3 is used to cool the compressed air within the airflow duct 2. Multiple heat sinks 4 are mounted on the exterior of the housing 1. By using the water-cooling structure 3 as the primary heat dissipation method, supplemented by the heat sinks 4 on the exterior of the housing 1, the compressed air temperature within the airflow duct 2 can be quickly reduced, preventing any impact on subsequent compressed air usage processes.

[0030] Reference Figure 1-2 The air inlet 11 and the air outlet 12 are both located at the lower end of the casing 1 and on the top surface of the casing 1; the air flow duct 2 is U-shaped and is divided into a curved section 21 and two straight sections 22; the water cooling structure 3 is located at the upper end of the casing 1, and multiple heat sinks 4 are fixed between the lower end of the casing 1 and the water cooling structure 3. The air inlet 11 and the air outlet 12 are located at the lower end, while the water cooling structure 3 is located at the upper end of the casing 1, utilizing the natural convection principle of hot air rising and cold air falling to ensure the stability of the compressed air circulation; the multiple heat sinks 4 are fixed between the lower end of the casing 1 and the water cooling structure 3 to fully utilize the space in the casing 1 and maximize the heat dissipation area; and the water cooling structure 3 further cools the air cooled by the U-shaped air flow duct 2 to ensure that the outlet temperature of the compressed air meets the requirements.

[0031] Reference Figure 2-3 The water-cooling structure 3 includes multiple cooling water pipes 31 and two fixed disks 32. A water inlet 13 and a water outlet 14 are respectively provided on the left and right sides of the upper end of the casing 1 along a horizontal straight line. The two fixed disks 32 are respectively threadedly connected to the water inlet 13 and the water outlet 14, and multiple mounting openings 321 are provided in the circumferential direction. The multiple mounting openings 321 correspond to the multiple cooling water pipes 31, and the two ends of the cooling water pipes 31 are respectively connected to the mounting openings 321 corresponding to the fixed disks 32 on both sides; the middle end of the cooling water pipe 31 is wrapped around the outer circumference of the curved pipe section 21 of the airflow pipe 2. The cooling water circulates in the pipe, which can effectively absorb and carry away the heat generated by the curved pipe section 21, thereby significantly reducing the temperature of the airflow pipe 2 and improving the overall heat dissipation efficiency. Since the fixed disk 32 is threadedly connected to the water inlet 13 and the water outlet 14, it can be easily disassembled by the operator when replacement is required.

[0032] Reference Figure 2 Multiple washers 5 are installed in the airflow duct 2 and are fixed in sequence on the straight section 22 between the air inlet 11 and the water-cooling structure 3. As the compressed air flows from the air inlet 11 to the cooling structure in the airflow duct 2, it collides with each annular washer 5 it passes through. This collision causes part of the compressed air to change direction, thereby slowing the flow rate of the compressed air and giving it more time to cool.

[0033] Reference Figure 2 A cylindrical plug 6 is installed in the air flow duct 2. The cylindrical plug 6 is located on the straight section 22 between the water-cooling structure 3 and the air outlet 12. The cylindrical plug 6 is vertically provided with a through hole 61 in the up-down direction, and both ends of the through hole 61 are chamfered. Compressed air flows from a large-diameter pipe into a small-diameter pipe. In this process, due to the reduction in the cross-sectional area of the pipe, the gas will be hindered by the pipe wall during contraction, and part of the kinetic energy will be converted into pressure energy, resulting in an increase in gas pressure, reducing the situation where the compressed air pressure decreases after cooling; and because the compressed air will pass through the heat sink 4 again, the little heat generated will be dissipated to avoid affecting the outlet temperature.

[0034] Reference Figure 1-2 Two pressure relief holes 15 are respectively formed in the two straight sections 22 of the air flow duct 2. The two pressure relief holes 15 penetrate the casing 1 and are located at the front face of the casing 1. The pressure relief holes 15 are usually blocked by pressure plugs. However, the design of the pressure relief holes 15 allows the compressed air to be directly released when the internal pressure of the air compressor rises abnormally, preventing the pipeline from rupturing or other safety accidents due to overpressure.

[0035] Reference Figure 1 Mounting blocks 7 are installed at the air inlet 11 and air outlet 12, respectively. Threaded holes 71 are provided on both ends of the mounting blocks 7, extending completely through the housing 1. The threaded holes 71 are located on either side of the straight section 22 of the air duct 2. The mounting blocks 7 are used to attach to the air compressor. The design of the mounting blocks 7 provides a secure support for bolting the air inlet 11 and air outlet 12 to the air compressor, ensuring that the interfaces will not loosen or leak under high-pressure or high-velocity airflow conditions.

[0036] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
