Abstract
Description
Technical Field
[0001] This utility model relates to the field of air cooler with staggered finned tubes. Background Technology
[0002] Air coolers, as essential unit equipment in technological processes, are widely used in engineering fields such as petroleum, chemical, power, light industry, machinery, metallurgy, transportation, and pharmaceuticals. Air coolers typically use air as the cooling medium and achieve heat transfer through forced convection heat exchange. Their core working principle is as follows: high-temperature process fluids (such as oil, gas, hot water, etc.) flow within a tube bundle, while external air, driven by a fan, sweeps laterally across the tube bundle fins, carrying away heat from the tube bundle through heat conduction and convection, thereby reducing the fluid temperature.
[0003] Existing air coolers typically exchange heat between the medium inside the tubes using fans and sprayed cooling water. Their finned tube structures are mostly simple, with a single air duct, resulting in low utilization of the sprayed water and low cooling efficiency of the medium inside the tubes. Therefore, improvements to the existing technology are still needed. Utility Model Content
[0004] To address the aforementioned problems, this invention provides an air cooler with staggered finned tubes that offers excellent cooling performance.
[0005] This utility model provides the following solution to the problems mentioned above:
[0006] An air cooler with staggered finned tubes includes a heat dissipation device and a housing. The heat dissipation device is mounted on the side wall of the housing, and a spray pipe is located above the heat dissipation device. Multiple blowers are also located on the top of the housing. The heat dissipation device contains several finned tubes that pass through several heat dissipation plates. Support plates are located at both ends of the finned tubes. A distributor is located at both ends of the heat dissipation device. Heat dissipation fins are evenly arranged on the finned tubes. The heat dissipation fins are inclined, annular, and plate-like structures. The finned tubes are stacked within the heat dissipation device, with the front and rear ends of the stacked finned tubes facing opposite directions. The spray pipe is mounted on the side wall of the housing. The heat dissipation fins are inclined at an angle of 20° to 30°. The angles of the heat dissipation fins within the heat dissipation device are staggered, creating turbulence as air passes between the fins, significantly improving the heat dissipation effect of the heat dissipation device.
[0007] Preferably, the heat sink has an uneven annular heat dissipation pattern; the heat sink is sleeved on the finned tube, and the heat sink and the finned tube are welded together. Both the finned tube and the heat sink are made of high thermal conductivity materials. The heat sink also has heat dissipation pattern, which can prolong the contact time and contact area between the spray water and the heat sink, and greatly improve the cooling efficiency.
[0008] Preferably, the blower is equipped with a dustproof device, the bottom of the housing is provided with a cavity, and the side walls of the bottom of the housing are provided with dustproof windows; the dustproof device and dustproof windows can maintain the cleanliness of the housing, and the cavity can make the air circulation inside the housing smoother.
[0009] Preferably, the spray pipe has a three-branched structure, and the bottom of the spray pipe is also provided with evenly arranged spray nozzles; the branched structure of the spray pipe covers a larger area, and the evenly arranged multiple spray nozzles can spray water evenly onto the heat dissipation device, so as to fully exchange heat with the internal medium of the finned tube.
[0010] The beneficial effects of this utility model are as follows: This utility model is reasonably designed. Through the interlaced heat dissipation fins on the heat dissipation device and the heat dissipation texture on the heat dissipation fins, the contact time and contact area between the spray water and the heat dissipation fins are extended, thereby extending the heat exchange time. The stacked finned tubes can also create a turbulence effect in the air duct, which greatly improves the overall heat dissipation effect. The reasonably designed air duct and drainage save space while ensuring heat dissipation efficiency. The dustproof device on the top blower and the dustproof baffle at the bottom can prevent dust and maintain the cleanliness of the inside of the box. Attached Figure Description

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0021] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.
[0022] like Figure 1-6 The air cooler shown includes a heat dissipation device 2 and a housing 1. The heat dissipation device 2 is mounted on the side wall of the housing 1. A spray pipe 4 is provided above the heat dissipation device 2. Multiple blowers 3 are also provided on the top of the housing 1. Several finned tubes 5 are provided inside the heat dissipation device 2. The finned tubes 5 pass through several heat dissipation plates 8. Support plates 7 are provided at both ends of the finned tubes 5. A liquid distributor 6 is provided at both ends of the heat dissipation device 2. Heat dissipation fins 9 are evenly arranged on the finned tubes 5. The heat dissipation fins 9 are inclined annular plate structures. The finned tubes 5 are stacked in the heat dissipation device 2, and the front and rear ends of the stacked finned tubes 5 face opposite directions. The spray pipe 4 is mounted on the side wall of the housing 1. The heat dissipation fins 9 are in an inclined state. The inclination angle of the heat dissipation fins 9 is 20° to 30°. The angles of the heat dissipation fins 9 in the heat dissipation device 2 are interlaced. The airflow passing through the heat dissipation fins 9 will form turbulence, which will greatly improve the heat dissipation effect of the heat dissipation device 2.
[0023] The heat sink 9 has an uneven annular heat dissipation pattern 10; the heat sink 9 is sleeved on the finned tube 5, and the heat sink 9 and the finned tube 5 are welded together. Both the finned tube 5 and the heat sink 9 are made of high thermal conductivity materials. The heat sink 9 also has heat dissipation pattern 10, which can prolong the contact time and contact area between the spray water and the heat sink 9, and greatly improve the cooling efficiency.
[0024] The blower 3 is equipped with a dustproof device 11, the bottom of the housing 1 is provided with a cavity 12, and the side walls at the bottom of the housing 1 are all provided with dustproof windows 13; the dustproof device 11 and the dustproof windows 13 can maintain the cleanliness inside the housing 1, and the cavity 12 can make the air circulation inside the housing 1 smoother.
[0025] The spray pipe 4 has a three-branched structure, and the bottom of the spray pipe 4 is also provided with evenly arranged spray nozzles. The branched structure of the spray pipe 4 covers a larger area, and the evenly arranged multiple spray nozzles can spray water evenly onto the heat dissipation device 2, so as to fully exchange heat with the internal medium of the finned tube 5.
[0026] The following is the method of using this utility model: The high-temperature medium waiting for heat exchange enters from the inlet end of the heat dissipation device 2, passes through the distributor 6 and enters the finned tube 5. The high-temperature medium exchanges heat with the medium outside the finned tube 5 inside the finned tube 5, and finally achieves cooling. The cooled medium is discharged from the other end of the heat dissipation device 2. The external cooling medium is divided into two paths: spray water and air duct. The air is blown in from the blower 3 at the top, and the spray water is evenly sprayed on the heat dissipation device 2 through the spray pipe 4. After the air and spray water exchange heat through the heat exchange device, the hot air is blown out from the dustproof window 13 at the bottom, and the spray water is discharged from the outlet of the box 1. Both ends of the heat dissipation device 2 are sealed. The tilt angle of the heat dissipation fins 9 is 20° to 30°. The heat dissipation fins 9 and the finned tube 5 are welded together.
[0027] This utility model has a reasonable design. Through the interlaced heat dissipation fins on the heat dissipation device and the heat dissipation texture on the heat dissipation fins, the contact time and contact area between the sprayed water and the heat dissipation fins are extended, thereby extending the heat exchange time. The stacked finned tubes can also create a turbulence effect in the air duct, which greatly improves the overall heat dissipation effect. The reasonable air duct and drainage design saves space while ensuring heat dissipation efficiency. The dustproof device on the top blower and the dustproof baffle at the bottom can prevent dust and keep the inside of the box clean.
