Description

Technical Field

[0001] The utility model belongs to the technical field of air coolers, in particular to an air cooler which is easy to descale. Background Art

[0002] The abbreviation of air cooler is a heat exchange equipment that is most widely used for condensation and cooling in petrochemical and oil and gas processing production. Air coolers are generally composed of tube bundles, tube boxes, fans, shutters and frames. Air coolers are also called fin fans, which are often used to replace the cooling medium of water-cooled shell-and-tube heat exchangers. Air coolers use ambient air as the cooling medium, sweeping across the outside of the finned tubes to cool or condense the high-temperature process fluid in the tubes. Existing air coolers are more troublesome to clean the internal dirt.

[0003] The publication number is CN220304324U, an air cooler that is easy to descale. The air pump sends outside air into the shell through the air inlet pipe. At this time, the air does not immediately participate in the heat exchange, but first enters the dust washing water. After the dust washing water removes impurities in the air, the air overflows from the dust washing water. Through the design of the water liquid, dirt can be collected. At the same time, the contact of the water liquid also plays a role in improving heat dissipation. However, after long-term use, the water liquid is prone to heat up, which is not conducive to improving heat dissipation. Utility Model Content

[0006] In a further embodiment, the axial flow fan is composed of a circular ring shell and a plurality of axial flow blades, and the plurality of axial flow blades are designed to be fixedly connected to the circular ring.

[0007] In a further embodiment, an outer side of the ring gear is provided with an inclined serration portion, and one end of the rotating rod is designed to penetrate the circular frame and be rotatably connected.

[0008] In a further embodiment, a bevel gear is connected to the through end of the rotating rod, and the outer periphery of the bevel gear is meshed with the outer periphery of the ring gear.

[0009] In a further embodiment, a plurality of annular fins are fixed to the outer periphery of the guide coil, and the air outlet end of the guide coil is located in the upper half of the main shell.

[0010] In a further embodiment, the top of the circular frame is connected to a disc-shaped exhaust plate, and a diffuser plate for uniform exhaust is fixed on the top of the exhaust plate.

[0011] In a further embodiment, the lower half of the inner circumference of the main shell contains water for collecting dirt, and the air pipe is designed to pass through the water.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The water-liquid design in the lower half of the inner periphery of the main shell can collect dirt in a centralized manner, guide the lower half of the coil to contact with the water-liquid, and the cooling and heat dissipation design of the annular fins and fin groups. At the same time, the suction of the fan generates negative pressure to make the sucked external air contact and mix with the cooled air in the upper half of the main shell, and then discharge it to contact with the fin group, which can greatly improve the cooling design;

[0015] The axial fan has a rotating design of an annular shaft ring and a tilting design of multiple axial fan blades. When the fan draws air at high speed, the vortex fan can rotate. The meshing design of the annular gear and the bevel gear and the connection of the rotating rod and the bevel gear are used to stir the water liquid. At the same time, the wind force generated when the air is drawn blows the water liquid, which can further dissipate the temperature of the water liquid efficiently, avoiding the high temperature of the water liquid for a long time and affecting the cooling.

[0016] The air cooler, which is easy to descale, is convenient for collecting dirt through the water-liquid design and is driven by the wind power generated by itself, which cools the water-liquid while not increasing resource consumption. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of annular fins 3 are fixed on the outer periphery of the guide coil 2;

[0031] The bottom of the round frame 4 is connected to a plurality of air pipes 7, which are curved in design. Water passes through the periphery of the air pipe 7, which can cool down the air and collect dirt through the mixing of liquid and impurities. An opening is provided on one side of the main shell 1, through which the water containing dirt can be discharged.

[0032] See also Figures 2 to 4 In order to cool the water, the outer circumference or bottom of the circular frame 4 is fixed by a bracket, a notch is provided on the top of the circular frame 4, an exhaust plate 9 is installed on the inner circumference of the notch, the exhaust plate 9 is a conical structure, and a diffuser plate 10 is installed on the top of the exhaust plate 9;

[0033] The inner wall of the lower half of the inner circumference of the circular frame 4 is provided with a ring shaft ring 8, and the inner ring of the ring shaft ring 8 is connected with an axial flow fan 21, which is composed of a circular ring shell and a plurality of axial flow blades.

[0036] How it works

[0037] When the air cooler is easy to descale, hot air is input into the upper half of the inner circumference of the main shell 1 through the guide coil 2 when it is needed. During the input process, the annular fins 3 on the outer circumference of the guide coil 2 and the contact with the water liquid can further play a role in heat dissipation and temperature reduction.

[0038] At the same time, the fan 5 is started to suck gas through the air pipe 7, further generating negative pressure, so that the external air passes through the fin group 6 and interacts with the hot gas to achieve cooling. At the same time, the gas is sucked into the circular frame 4 again, diffused and discharged through the diffuser plate 10, and heatsinked with the fin group 6;

[0039] When the gas enters the circular frame 4, the axial flow fan 21 is driven to rotate separately, so that the ring gear 22 rotates, and the bevel gear 32 and the rotating rod 31 rotate, and the stirring blades 33 further stir the water, and the water is blown by the wind to achieve heat dissipation.
