Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to an air-cooled heat exchange device with air guide fins. Background Technology

[0002] Air coolers are commonly used heat exchange devices in industrial and civil fields, relying on air as the cooling medium to reduce fluid temperature. Air coolers with guide fins incorporate a guide fin design into traditional air coolers, enhancing heat transfer through the interaction of airflow and the fins. They are widely used in chemical, power, and refrigeration industries, require no water resources, are adaptable to various environments, and are a common type of equipment for achieving high-efficiency heat exchange and energy saving.

[0003] Utility model patent CN216245694U discloses a tube-and-box type air cooler. This air cooler includes an air cooler body and two cover plates. The air cooler body has an air cooler tube box, finned tubes, and a tube box. The cover plates have mounting grooves and fixing grooves. Multiple positioning rods are connected to both the air cooler tube box and the tube box. Multiple positioning holes matching the positioning rods are provided on the cover plates. Multiple insertion rods are slidably mounted on the cover plates, and the positioning rods have insertion holes matching the insertion rods. A locking assembly is connected to the cover plates. Baffles are connected to the insertion rods, and a limiting assembly is connected to the cover plates. The limiting assembly includes multiple limiting blocks, and multiple limiting grooves matching the limiting blocks are provided on the cover plates. The limiting blocks and limiting grooves are in sliding engagement. A limiting frame is connected to the limiting blocks, and the limiting frame contacts the baffle. A movable assembly is detachably connected to the cover plates, and the movable assembly is connected to a fixing component.

[0004] In this tube-and-box type air cooler, heat exchange only occurs at the contact level between the fluid and the inner wall of the finned tube. It cannot directly exchange heat with the fluid inside, nor does it have a design that actively exchanges heat with the fluid inside. This results in a single heat exchange path, easy temperature difference between the inner and outer layers of the fluid, and insufficient initiative and targeting of heat exchange, making it difficult to achieve a rapid and uniform reduction in the overall temperature of the fluid. In view of this, we propose an air-cooled heat exchange device for air coolers with guide fins. Utility Model Content

[0005] The purpose of this invention is to provide an air-cooled heat exchange device for an air cooler with guide fins, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An air-cooled heat exchange device with guide fins includes an air-cooled body. The air-cooled body includes a pair of liquid collection seats distributed symmetrically on the left and right, several flat flow channels connected between the two liquid collection seats, and a first fan installed between the bottom ends of the two liquid collection seats. The first fan blows air upwards, and the fluid enters one of the liquid collection seats and flows to the other liquid collection seat through the flat flow channels. Several guide fins are provided on the front and rear surfaces of the flat flow channels. The air cooler body is equipped with a heat exchange assembly, which is used to further heat the fluid flowing through the flat flow channel. The heat exchange assembly includes an air inlet fixed to the top of the liquid collection seat at the left end, an air outlet fixed to the top of the liquid collection seat at the right end, and a heat exchange sleeve fitted inside the flat flow channel. The left and right ends of the heat exchange sleeve are connected to the air inlet and air outlet by flat pipes. Several second fans are installed on the outer end face of the air inlet. Under the operation of the second fans, the outside air flows along the air inlet, heat exchange sleeve and air outlet.

[0007] Preferably, a connecting pipe is fixed to the outer end of the liquid collecting base, the connecting pipe is connected to the interior of the liquid collecting base, and the pipe opening is provided with a flange.

[0008] Preferably, the flat flow channel has a flat rectangular tube structure, the side surface of the flat flow channel is vertical, and a number of guide fins are vertically fixed on the side surface of the flat flow channel and arranged at equal intervals along the length of the flat flow channel. In this design, the flat structure increases the contact area between the flat flow channel and the air, the guide fins further expand the heat exchange area and guide the airflow, and the evenly spaced arrangement ensures a balanced heat exchange effect.

[0009] Preferably, the heat exchange sleeve has a hollow cuboid structure, and is centrally fitted inside the flat flow channel. The vertical height of the heat exchange sleeve is less than the height of the internal space of the flat flow channel.

A vertical retaining plate is fixed on the top and bottom end faces of the heat exchange sleeve. The thickness of the retaining plate is less than the thickness of the heat exchange sleeve. The outer ends of the two retaining plates abut against the top and bottom inner walls of the flat flow channel, respectively. In this setup, the hollow structure allows airflow to achieve internal heat exchange, the central placement ensures uniform heating of the fluid, maintains the fixed position of the heat exchange sleeve, and reduces obstruction to fluid flow.

[0010] Preferably, the left and right ends of the front end face of the flat flow channel are provided with openings, and the left and right ends of the front end face of the heat exchanger are provided with connecting holes. The positions of the two connecting holes correspond to the positions of the two openings respectively. The bottom end of the flat tube is connected to a convex tube, which passes through the opening and communicates with the connecting hole. Preferably, the outer diameter of the convex tube is the same as the diameter of the connecting hole, the end of the convex tube is tightly welded to the opening of the connecting hole, the inner diameter of the through is larger than the diameter of the connecting hole, and the diameter difference between the connecting hole and the through forms a step, which is used to form a welding space between the flat flow channel and the flat tube. In these two settings, the through-hole and the connecting hole cooperate to allow the protruding tube to pass through, so as to connect the flat tube and the heat exchanger housing. The step provides welding space to ensure a stable connection and prevent air leakage.

[0011] Preferably, several connection ports are provided on the adjacent end faces of the air inlet seat and the air outlet seat, the first end of the flat tube is sleeved and fixed on the outside of the corresponding connection port, several air vents are provided on the left end face of the air inlet seat, the second fan cover is connected to the outside of the air vents, and several exhaust slots are provided on the right end face of the air outlet seat. In this setup, the flat tube at the connection port ensures stable airflow, the air inlet supplies air into the air inlet seat, and the exhaust duct promptly discharges the air after heat exchange, maintaining smooth airflow circulation.

[0012] Preferably, a pair of connecting rods are fixed between the front ends of the two liquid collecting seats and between the rear ends of the two liquid collecting seats, and the two liquid collecting seats are sleeved in the support frame and fixedly connected to the support frame. In this configuration, the connecting rod enhances the stability of the combined structure of the liquid collection seat and the flat flow channel, and the support frame supports the entire device, ensuring that the device is placed stably and reserving air intake space for the first blower.

Example

[0017] Please see Figures 1-3An air-cooled heat exchange device with guide fins includes an air-cooled body 100. The air-cooled body 100 includes a pair of liquid collection seats 110 symmetrically distributed on the left and right, several flat flow channels 120 connected between the two liquid collection seats 110, and a first fan 130 installed between the bottom ends of the two liquid collection seats 110. The two liquid collection seats 110 can temporarily store and divert the incoming fluid to ensure that the fluid can be evenly distributed into each flat flow channel 120. The flat flow channel 120 adopts a flat structure to increase the contact area with air, which is conducive to heat exchange between the fluid and the outside air. The first fan 130 blows air upward to guide the outside air to the flat flow channel 120 and the guide fins 121, providing active airflow conditions for fluid heat exchange. After entering one of the liquid collection seats 110, the fluid flows through the flat flow channel 120 to the other liquid collection seat 110.

[0018] like Figure 1 and Figure 2 As shown in the present invention, a connecting pipe 111 is fixed to the outer end of the liquid collecting seat 110. The connecting pipe 111 is connected to the interior of the liquid collecting seat 110. The pipe opening of the connecting pipe 111 is provided with a flange. The connecting pipe 111 can serve as a channel for fluid to enter and exit the liquid collecting seat 110, ensuring that the fluid can flow in and out stably. The flange facilitates the connection between the connecting pipe 111 and the external pipe, improves the sealing and stability of the connection, and avoids fluid leakage.

[0019] like Figures 1-3 As shown, specifically, the flat flow channel 120 has a flat rectangular tube structure. The side surface of the flat flow channel 120 is vertical. Several guide fins 121 are provided on both the front and rear sides of the flat flow channel 120. The guide fins 121 are vertically fixed on the side surface of the flat flow channel 120 and are arranged at equal intervals along the length of the flat flow channel 120. The vertically arranged guide fins 121 can further increase the contact area between the flat flow channel 120 and the air, and at the same time, they can guide the air blown by the first fan 130, so that the air flows more evenly across the surface of the flat flow channel 120, improving the heat exchange efficiency. The evenly spaced arrangement can ensure that the heat exchange effect of each guide fin 121 is balanced, avoiding local airflow accumulation or gaps.

[0020] like Figure 1 and Figure 2 As shown, furthermore, a pair of connecting rods 112 are fixed between the front ends of the two liquid collection seats 110 and between the rear ends of the two liquid collection seats 110. The two liquid collection seats 110 are sleeved in the support frame 140 and fixedly connected to the support frame 140. The connecting rods 112 can connect the two liquid collection seats 110 into a whole, enhance the stability of the combination structure of the liquid collection seat 110 and the flat flow channel 120, and prevent the components from shifting due to vibration during use. The support frame 140 can support the entire air cooler body 100, so that the device can be stably placed in the use position, while reserving sufficient air intake space for the first fan 130.

[0021] It is worth noting that the first fan 130 involved in this utility model is existing conventional technology, and will not be described in detail in this utility model.

[0022] In this embodiment, the air-cooled heat exchange device with guide fins is used as follows: First, the device is connected to the external fluid pipeline through the flange of the connecting pipe 111 to ensure that the fluid can smoothly enter the liquid collection seat 110. Then, the fluid flows from the external pipeline into one of the liquid collection seats 110, which evenly distributes the fluid into each flat channel 120. Next, the first fan 130 is started, and the first fan 130 blows air upward. The air flows through the surface of the flat channel 120 and the guide fins 121, and exchanges heat with the fluid in the flat channel 120. Finally, the fluid that has completed the heat exchange flows from the flat channel 120 into another liquid collection seat 110, and then flows out of the device through the connecting pipe 111 of the liquid collection seat 110, thus achieving the cooling treatment of the fluid. Example

[0023] To further exchange heat with the high-temperature fluid flowing through it, such as Figures 1-8 As shown, the air cooler body 100 is provided with a heat exchange assembly 200 for further heat exchange of the fluid flowing through the flat flow channel 120. The heat exchange assembly 200 includes an air inlet seat 210 fixed to the top of the liquid collection seat 110 at the left end, an air outlet seat 220 fixed to the top of the liquid collection seat 110 at the right end, and a heat exchange sleeve 230 sleeved inside the flat flow channel 120. The air inlet seat 210 can collect and distribute the air drawn in by the second fan 250, and the air outlet seat 220 can discharge the air that has completed internal heat exchange. The heat exchange sleeve 230 is sleeved inside the flat flow channel 120 and can directly contact the fluid inside the flat flow channel 120, providing a structural basis for heat exchange from inside the fluid. The left and right ends of the heat exchanger 230 are connected to the air inlet 210 and the air outlet 220 by flat tubes 240. The flat tubes 240 can serve as channels for air to flow between the air inlet 210, the heat exchanger 230 and the air outlet 220, ensuring that the air can circulate stably in the internal heat exchange path. Several second fans 250 are installed on the outer end face of the air inlet 210. The second fans 250 can actively draw in outside air to provide a continuous airflow for the internal heat exchange path and enhance the initiative of heat exchange. Under the operation of the second fans 250, outside air flows along the air inlet 210, the heat exchanger 230 and the air outlet 220.

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, several connection ports 211 are provided on the adjacent end faces of the air inlet seat 210 and the air outlet seat 220. The first end of the flat tube 240 is sleeved and fixed to the outside of the corresponding connection port 211. The connection port 211 can position the flat tube 240, ensuring that the flat tube 240 can accurately communicate with the air inlet seat 210 and the air outlet seat 220. The fixed connection between the first end of the flat tube 240 and the connection port 211 can prevent air leakage at the connection point and ensure that all airflow can enter the flat tube 240. On the left end face of the air inlet seat 210 Several air vents 212 are provided, and a second fan 250 is connected to the outside of the air vents 212. The air vents 212 are the channels for air to enter the air inlet seat 210. The connection of the second fan 250 to the outside of the air vents 212 can ensure that all the outside air can be drawn into the air inlet seat 210, reducing airflow loss. Several exhaust slots 221 are provided on the right end face of the exhaust seat 220. The exhaust slots 221 can quickly discharge the hot air that has completed heat exchange in the heat exchange jacket 230, avoid the accumulation of hot air in the exhaust seat 220, and ensure smooth internal airflow circulation.

[0025] like Figures 6-8 As shown, specifically, the heat exchanger housing 230 has a hollow cuboid structure. The heat exchanger housing 230 is centrally fitted inside the flat flow channel 120. The vertical height of the heat exchanger housing 230 is less than the height of the internal space of the flat flow channel 120. The hollow structure allows air to flow inside the heat exchanger housing 230. Its central placement ensures fluid distribution around the heat exchanger housing 230, achieving uniform heat exchange. The vertical height being less than the height of the internal space of the flat flow channel 120 prevents the heat exchanger housing 230 from obstructing fluid flow within the flat flow channel 120. The front and rear ends of the heat exchanger housing 230... The two retaining plates 232 are respectively abutted against the inner walls of the front and rear sides of the flat flow channel 120. A vertical retaining plate 232 is fixed on the top and bottom side end faces of the heat exchange jacket 230. The thickness of the retaining plate 232 is less than the thickness of the heat exchange jacket 230. The outer ends of the two retaining plates 232 abut against the inner walls of the top and bottom sides of the flat flow channel 120, and the front and rear end faces abut against the inner walls of the flat flow channel 120. With the retaining plates 232 abutting against the inner walls of the top and bottom sides of the flat flow channel 120, the heat exchange jacket 230 can be stably fixed inside the flat flow channel 120. The smaller thickness of the retaining plate 232 can reduce the obstruction to fluid flow.

[0026] like Figures 6-8As shown, furthermore, openings 122 are provided at both ends of the front end face of the flat flow channel 120, and connecting holes 231 are provided at both ends of the front end face of the heat exchange sleeve 230. The positions of the two connecting holes 231 correspond to the positions of the two openings 122 respectively. The bottom end of the flat tube 240 is connected to a convex tube 241. The convex tube 241 passes through the opening 122 and communicates with the connecting hole 231. The opening 122 provides a channel for the convex tube 241 to pass through the flat flow channel 120. The connecting hole 231 can realize the precise docking of the convex tube 241 and the heat exchange sleeve 230, ensuring that air can smoothly enter the heat exchange sleeve 230 from the flat tube 240 through the convex tube 241. The outer diameter of the convex tube 241 is the same as the diameter of the connecting hole 231. The end of the convex tube 241 is tightly welded to the opening of the connecting hole 231. The tight welding of the same diameter ensures the sealing between the convex tube 241 and the connecting hole 231 and avoids air leakage. The inner diameter of the through-hole 122 is larger than the diameter of the connecting hole 231. The diameter difference between the connecting hole 231 and the through-hole 122 forms a step. This step is used to form a welding space between the flat flow channel 120 and the flat tube 240. The welding space provides operating space for the welding and fixing of the flat flow channel 120 and the flat tube 240, ensuring that the two can be firmly connected and further improving the sealing and stability of the overall structure.

[0027] It is worth noting that the second fan 250 involved in this utility model is existing conventional technology, and will not be described in detail here.

[0028] In this embodiment, the air-cooled heat exchange device with guide fins is used as follows: First, the device is connected to an external fluid pipeline as in Embodiment 1. The fluid enters the liquid collection seat 110 and is diverted to the flat flow channel 120. Then, the first fan 130 and the second fan 250 are started. The first fan 130 blows air upwards to exchange heat on the outer surface of the flat flow channel 120, and the second fan 250 draws in outside air through the air inlet 212 of the air inlet seat 210. The air enters the flat tube 240 through the connection port 211 of the air inlet seat 210. Then, the flat tube 240... Air inside the tube 0 passes through the opening 122 of the flat flow channel 120 via the convex tube 241, enters the heat exchanger 230 through the connection hole 231, and exchanges heat with the fluid inside the flat flow channel 120 from the inside. Finally, the air that has completed the internal heat exchange flows out from the heat exchanger 230, enters the exhaust seat 220 through the flat tube 240 on the other side, and is discharged from the exhaust slot 221 of the exhaust seat 220. At the same time, the fluid that has completed the heat exchange flows from the flat flow channel 120 into another liquid collection seat 110 and flows out of the device, realizing dual heat exchange and cooling of the fluid.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
