Description

Technical Field

[0001] The present invention relates to the technical field of fin heat exchangers, and specifically relates to an efficient heat exchanger that enhances the heat conduction area between a fluid and heat dissipation fins. Background Art

[0002] A fin radiator is a heat exchange device that installs heat conduction fins on the outer side of a base tube (steel tube, stainless steel tube, etc.). In the industrial field, a fin heat exchanger is commonly used to cool high-temperature wastewater so that the temperature of the treated wastewater can meet the temperature for biodegradation. When cooling the wastewater, the high-temperature wastewater is pumped into the interior of the base tube, and the fins outside the base tube conduct the heat in the wastewater. At the same time, a blower at one end of the radiator blows air towards the fins to accelerate the air flow, and the air flow can carry away the heat conducted out from the fins, achieving the cooling of the wastewater.

[0003] At present, most fin heat exchangers are not easy to adjust the magnitude of the heat exchange and cooling degree according to the usage requirements. In winter with a relatively low ambient temperature, the wastewater needs to be cooled by a smaller degree compared to the hot summer. At this time, if the heat exchanger continues to maintain multiple base tubes cooperating with the fins to conduct a large degree of heat exchange for the wastewater, the wastewater is prone to overcooling. And microorganisms need an appropriate water temperature to maintain their activity. The overcooled wastewater may reduce the activity of microorganisms, thereby affecting the subsequent biodegradation effect of the wastewater. Moreover, the neatly arranged multi-row base tubes will cause the fins at different positions to block each other. It is not easy for the fins at the back to directly contact the air flow over a large area, which is not conducive to improving the heat exchange efficiency of the fins. Summary of the Invention

[0004] The purpose of the present invention is to provide an efficient heat exchanger that enhances the heat conduction area between a fluid and heat dissipation fins, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An efficient heat exchanger that enhances the heat conduction area between a fluid and heat dissipation fins, comprising:

[0007] A base;

[0008] A heat exchange box, fixed to the base;

[0009] Multiple heat exchange tube groups, all installed inside the heat exchange box and interconnected. Each heat exchange tube group includes four interconnected base tubes. Fins are fixed on the outer side of the base tubes. The multiple heat exchange tube groups in the heat exchange box are sequentially recorded as tube group one and two tube groups two from front to back. A water inlet pipe is connected to the top base tube of tube group one, and a drain pipe is connected to the bottom base tube of one of the tube groups two.

[0010] Two flow direction adjusting members are respectively arranged in communication with the tube group two at corresponding positions. The flow direction adjusting member can adjust the heat exchange and cooling degree of the tube group two. The flow direction adjusting member includes a support tube, and two positioning cylinders are fixed on the support tube. An activity cylinder connected and inserted with the base tube slides inside the positioning cylinder;

[0011] A water bucket is fixed to the base and can control the temperature of the water discharged from the drain pipe;

[0012] Two stirring mechanisms are both arranged inside the water bucket and can stir and mix high-temperature and low-temperature wastewater.

[0013] Furthermore, on both sides of the heat exchange box, a prior art component, a blower, and an exhaust pipe are respectively connected and fixed.

[0014] Furthermore, a first connecting pipe is connected between one ends of two adjacent base tubes on the tube group one and between one ends of two middle base tubes on the tube group two. A second connecting pipe is connected between the bottom base tube of the tube group one and the bottom base tube of the adjacent tube group two. A third connecting pipe is connected between the top base tubes of the two tube groups two.

[0015] Furthermore, both ends of the support tube are connected and communicated with the corresponding base tubes. The flow direction adjusting member further includes an electric push rod fixed to the heat exchange box, and the output end of the electric push rod can drive the two activity cylinders to move inside the positioning cylinders.

[0016] Furthermore, a water tank is fixed to the outside of the water bucket, and two partition plates are fixed inside the water bucket. The two partition plates divide the internal space of the water bucket into a cold water chamber and two detection chambers.

[0017] Furthermore, a first water delivery pipe is connected between the cold water chamber of the water bucket and the two detection chambers, and a water extraction pipe is connected between the two detection chambers of the water bucket.

[0018] Furthermore, a water temperature detector is installed at the middle position of the outside of the water bucket near the detection chamber. Two rectangular holes both communicated with the water tank are opened on the outside of the water bucket, and the drain pipe is connected with the water tank.

[0019] Furthermore, the stirring mechanism is arranged inside the detection chamber of the water bucket at the corresponding position. The stirring mechanism includes:

[0020] A stirring shaft is rotatably connected to the water bucket. A three-pronged bracket is fixed to one end of the stirring shaft. Motors capable of driving the stirring shaft to rotate are fixed to both the top and bottom of the water bucket;

[0021] A plurality of paddle blades are all fixed to the bottom surface of the three-pronged bracket;

[0022] An annular plate is fixed to the plurality of paddle blades, and a notch is opened on the outside of the annular plate.

[0023] Furthermore, the outer side of the drainage pipe is connected and fixed with a water delivery pipe 2, and the top of the water delivery pipe 2 is connected and fixed with the cold water cavity.

[0024] Furthermore, the outer side of the water inlet pipe is connected and fixed with a water delivery pipe 3, and the bottom of the water delivery pipe 3 is connected and fixed with two detection chambers.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. A tube group 1 and two tube groups 2 for heat exchange are fixed inside the heat exchange box, a support tube is connected between the top base tube and the bottom base tube of the tube group 2, a positioning cylinder is fixed in the middle of the support tube, and a movable cylinder is slidably connected inside the positioning cylinder. When the output end of the electric push rod drives the circular hole position of the movable cylinder to move to the inside of the support tube, the two ends of the support tube are respectively connected with the movable cylinders at the corresponding positions, and because the end of the movable cylinder away from the circular hole is connected with the base tube in the middle of the tube group 2, multiple base tubes on the tube group 2 are connected in series end to end, and the base tube of the tube group 1 is connected to the base tube of the adjacent tube group 2 by a fixed connecting tube 2, and the base tubes of the two tube groups 2 are connected by a fixed connecting tube 3, so that the high-temperature wastewater pumped by the water inlet pipe can pass through the base tubes of multiple heat exchange tube groups at the same time, and the fins outside the base tubes conduct the heat of the wastewater to achieve maximum cooling of the wastewater.

[0027] 2. The circular hole of the movable cylinder is driven to leave the support tube through the output end of the electric push rod, so that the sealed end of the movable cylinder moves to the open end of the positioning cylinder. At this time, the circular hole is not connected with the support tube, so that the movable cylinder no longer connects the two base tubes in the middle of the second tube group with the support tube. The two ends of the support tube directly connect the two base tubes at the top and bottom of the second tube group, so that only two heat exchange base tubes in the second tube group perform heat exchange work. Similarly, multiple base tubes in the other second tube group can also stop part of the base tubes from cooling the wastewater through the support tube and the movement of the movable cylinder. In the summer when the temperature is high, multiple base tubes can be made to work with the fins to exchange heat with water. In the winter when the temperature is low, fewer base tubes can be selected to work with the fins to exchange heat with water, so as to realize the selection of a suitable number of base tubes and fins to cool the wastewater according to needs, which is convenient for adjusting the degree of heat exchange cooling and effectively preventing the heat exchanger from over-cooling the wastewater.

[0028] 3. By staggering the distribution of two adjacent base tubes and fins on different heat exchange tube groups, the base tubes and fins at different positions can face the airflow blown from the fan. Compared with the traditional adjacent base tube and fin shielding arrangement, the direct contact area between the fin and the airflow can be increased, which is beneficial to improve the efficiency of fin heat exchange.

[0029] 4. A water bucket is fixed on one side of multiple heat exchange tube groups. The inside of the water bucket is separated into a cold water chamber and two detection chambers by a partition. A water temperature detector is installed and fixed inside the detection chamber. The wastewater cooled by the heat exchange tube groups flows into the detection chamber. The water temperature detector can detect the water temperature. If the water temperature is higher than the biodegradation temperature, the first water delivery pipe transports the low-temperature water in the cold water chamber into the detection chamber to neutralize the water with a temperature higher than the biodegradation temperature. If the water temperature is lower than the biodegradation temperature, the third water delivery pipe transports the unheated high-temperature wastewater into the detection chamber to neutralize the water with a temperature lower than the biodegradation temperature. Thus, in the early stage, the temperature of the wastewater after heat exchange is initially controlled by adjusting the degree of heat exchange and cooling, and in the later stage, the water temperature can be finely regulated by adding hot water or cold water, facilitating the heat exchanger to cool out wastewater at a temperature meeting the requirements for biodegradation.

[0030] 5. By arranging two detection chambers in the water bucket, when detecting and adjusting the water temperature in one detection chamber closed by an annular plate, the other detection chamber can hold the wastewater continuously transported from the heat exchange tube groups. Thus, the two detection chambers can cycle to hold water for detecting and adjusting the water temperature, which is beneficial for the heat exchanger to continuously and efficiently discharge wastewater at an appropriate temperature. The water temperature is detected by the water temperature detector, a component of the prior art, facilitating the user to adjust the degree of heat exchange and cooling water of the heat exchange tube groups according to the water temperature after heat exchange. If the detected water temperature is high, the number of base tubes and fins for heat exchange is increased. If the detected water temperature is low, the number of base tubes and fins for heat exchange is decreased. Description of the Drawings

Specific implementation mode

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1, please refer to Figure 1 - Figure 8 , in the embodiment of the present invention, a high-efficiency heat exchanger for enhancing the heat conduction area between fluid and heat dissipation fins includes a base 100. One end of the top of the base 100 is fixedly provided with a heat exchange box 200. A plurality of interconnected heat exchange tube groups 300 are fixedly installed inside the heat exchange box 200. The heat exchange tube group 300 includes a plurality of interconnected base tubes 310. Fins 320 are fixedly provided on the outer side of each base tube 310. The multiple heat exchange tube groups 300 in the heat exchange box 200 are sequentially recorded as tube group one and two tube groups two from front to back. A water inlet pipe 350 is connected and fixed to the base tube 310 at the top of tube group one. A drain pipe 370 is connected and fixed to the base tube 310 at the bottom of one tube group two.

[0042] Specifically, by arranging the multiple heat exchange tube groups 300 in a staggered manner in height, the base tubes 310 and fins 320 on adjacent heat exchange tube groups 300 can be staggered, so that the heat dissipation air flow can directly blow to the outer sides of the base tubes 310 and fins 320 at different positions, which is beneficial to increasing the direct contact area between the fins 320 and the air flow. Thus, after the high-temperature wastewater passes through multiple series-connected base tubes 310, the fins 320 can efficiently export the heat in the wastewater, which is beneficial to improving the heat exchange efficiency of the heat exchanger.

[0043] An efficient heat exchanger that enhances the heat conduction area between the fluid and the heat dissipation fins further includes two flow direction adjusting members 400. The two flow direction adjusting members 400 are respectively connected and arranged at one end of the corresponding tube group two. The flow direction adjusting member 400 includes a support tube 410 fixed to the inner side of the heat exchange box 200. Two positioning cylinders 420 are embedded and fixed in the middle of the support tube 410. The positioning cylinder 420 is communicated with the support tube 410. An activity cylinder 430 that is communicated and inserted with the base tube 310 is slidably connected inside the positioning cylinder 420.

[0044] Specifically, by adjusting the position of the activity cylinder 430 inside the positioning cylinder 420, the activity cylinder 430 can be communicated with or not communicated with the support tube 410. If the activity cylinder 430 is communicated with the support tube 410, it is convenient to realize the head-to-tail series connection of multiple base tubes 310 on the tube group two to cool the waste water to the greatest extent. If the activity cylinder 430 is not communicated with the support tube 410, the two base tubes 310 at the middle position of the tube group two perform heat exchange work, and only the two base tubes 310 at the top and bottom perform heat exchange work, which is convenient to realize the head-to-tail series connection of a small number of base tubes 310 on the tube group two to cool the waste water to a smaller extent, so as to realize the flexible adjustment of the heat exchange cooling water degree of the heat exchanger.

[0045] Furthermore, a water bucket 500 is fixedly connected to the other end of the top of the base 100. The water bucket 500 can not only temporarily cache the cooled waste water, but also regulate the temperature of the waste water discharged from the drain pipe 370. Two stirring mechanisms 600 are arranged inside the water bucket 500, and the stirring mechanisms 600 can stir and mix waste water at different temperatures.

[0046] Specifically, the waste water discharged from the heat exchange tube group 300 is cached by the water bucket 500. The water bucket 500 can first detect whether the water temperature meets the temperature required for biodegradation, and re-adjust the temperature of the waste water with unqualified water temperature, so that the waste water finally discharged from the heat exchanger can meet the needs of biodegradation.

[0047] Such as Figure 1 and Figure 2 As shown, in this embodiment, an existing technology component, a blower 210, is fixedly connected and communicated with one side of the heat exchange box 200. A fan blade is rotatably installed inside the blower 210. The rotation of the fan blade can blow air to the fins 320, which is convenient for the fins 320 to exchange heat. The structure of the blower 210 is an existing technology component, and the specific working principle will not be elaborated.

[0048] In this embodiment, referring to Figure 2 , an exhaust pipe 220 is fixedly connected and communicated with the other side of the heat exchange box 200. The exhaust pipe 220 can lead out the hot air flow inside the heat exchange box 200 to complete the air flow exchange of the heat exchange box 200. Filter meshes are installed and fixed at the openings of both the blower 210 and the exhaust pipe 220, which can effectively prevent sundries from entering the inside of the heat exchange box 200.

[0049] Such asFigure 4 and Figure 5 As shown in Figure 5 , in this embodiment, a first connecting pipe 330 is fixedly connected and communicated between the ends of two adjacent base pipes 310 on the first pipe group and between the ends of two base pipes 310 in the middle of the second pipe group. A second connecting pipe 340 is fixedly connected and communicated between the base pipe 310 at the bottom of the first pipe group and the adjacent base pipe 310 at the bottom of the second pipe group. A third connecting pipe 360 is fixedly connected and communicated between the top base pipes 310 of the two second pipe groups.

[0050] In this embodiment, when multiple heat exchange pipe groups 300 cool the cooling water to the greatest extent, the waste water is pumped to the position of the water inlet pipe 350 through an external pipeline, and then flows from the water inlet pipe 350 between multiple base pipes 310 connected in series at the head and tail on the first pipe group. Then, the waste water on the first pipe group is transported to the second pipe group in the middle position through the second connecting pipe 340 and flows between multiple base pipes 310 connected in series at the head and tail on this second pipe group. Then, the waste water on this second pipe group is transported to between multiple base pipes 310 connected in series at the head and tail on the last second pipe group through the third connecting pipe 360, realizing the series flow of the waste water between all the base pipes 310. Finally, the heat-exchanged waste water flows into the interior of the water tank 510 along the drain pipe 370.

[0051] In this embodiment, referring to Figure 5 , the dotted lines marked on the second connecting pipe 340 and the third connecting pipe 360 indicate the specific connection and installation of the second connecting pipe 340 and the third connecting pipe 360 with a base pipe 310 at a certain position. Among them, the outer sides of the first connecting pipe 330, the second connecting pipe 340, the third connecting pipe 360, and the support pipe 410 are all fixedly connected to the inner side of the heat exchange box 200, so that the heat exchange pipe group 300 can be stably installed inside the heat exchange box 200.

[0052] As Figure 5 and Figure 6 shown, in this embodiment, both ends of the support pipe 410 are communicated with the corresponding base pipe 310. The flow direction adjusting member 400 further includes an electric push rod 440 fixed to the heat exchange box 200. The output end of the electric push rod 440 is fixed with a cross beam 441. Both ends of the cross beam 441 are fixedly connected to the corresponding movable cylinders 430. A circular hole 431 is opened at one end of the movable cylinder 430. The circular holes 431 on two adjacent movable cylinders 430 are symmetrically opened.

[0053] In this embodiment, when the output end of the electric push rod 440 extends, the cross beam 441 drives the circular holes 431 of the two movable cylinders 430 to move into the positioning cylinder 420, so that the movable cylinders 430 are not communicated with the support pipe 410. At this time, the base pipe 310 at the bottom of the second pipe group is directly communicated with the top base pipe 310 through the support pipe 410, and the wastewater will not flow into the two base pipes 310 in the middle of the second pipe group. When the output end of the electric push rod 440 shortens, the cross beam 441 drives the circular holes 431 of the two movable cylinders 430 to be inserted into the support pipe 410. The base pipes 310 at the bottom and top of the second pipe group are both communicated with the middle base pipe 310 through the support pipe 410 and the movable cylinders 430, so that the multiple base pipes 310 on the second pipe group are connected in series end to end, and the wastewater can flow in all the base pipes 310 on the second pipe group.

[0054] As Figure 7 shown, in this embodiment, a water tank 510 is fixed on the outside of the water bucket 500. One side of the water tank 510 is open. Two partition plates 520 are fixed inside the water bucket 500. The two partition plates 520 divide the internal space of the water bucket 500 into a cold water chamber and two detection chambers. The cold water chamber is used to hold the wastewater with a lower temperature, which can pre - enable multiple heat exchange pipe groups 300 to work to the maximum extent, and then temporarily store the over - cooled wastewater in the cold water chamber for later neutralizing the wastewater with a higher temperature.

[0055] In this embodiment, a first water delivery pipe 530 is communicated between the cold water chamber of the water bucket 500 and the two detection chambers. A water pump, a component of the prior art, is installed and fixed at the top of the first water delivery pipe 530. Two first branch pipes are communicated and fixed on the outside of the first water delivery pipe 530. The two branch pipes are respectively communicated and fixed with the corresponding detection chambers on the water bucket 500. The water pump can transport the low - temperature wastewater to the positions of the two first branch pipes. By opening the valves on different first branch pipes, the low - temperature water can be transported to different detection chambers. In order to make the water temperature in the cold water chamber lower, existing technology equipment (such as a chiller) can also be used to cool the water in the cold water chamber. The specific cooling method is selected according to the required equipment and will not be elaborated here.

[0056] As Figure 1 and Figure 7 shown, in this embodiment, a water extraction pipe 540 is communicated and fixed between the two detection chambers of the water bucket 500. The water extraction pipe 540 is connected and installed with the external water extraction and drainage pipeline. By opening the valves at different positions on the water extraction pipe 540, the temperature - adjusted wastewater in different detection chambers can be successively and continuously transported out.

[0057] In this embodiment, with reference to Figure 7A water temperature detector 550 is installed on the outside of the water bucket 500 near the middle of the detection cavity. The water temperature detector 550 is arranged above the annular plate 630 and will not interfere with the rotation of the annular plate 630. The water temperature detector 550 is mainly used to detect the water temperature inside the detection cavity. The water temperature detector 550 is a prior art component, and the specific temperature measurement principle is not repeated here.

[0058] like Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, two rectangular holes 570 are formed through the outer side of the water bucket 500 and are connected to the water tank 510. The drain pipe 370 is connected and fixed to the water tank 510. A notch 631 is formed on the outer side of the annular plate 630. The water cooled by the heat exchange tube group 300 flows into the water tank 510 through the drain pipe 370, and then the water flows from the open mouth of the water tank 510 through the rectangular holes 570 at different positions to different detection chambers.

[0059] In this embodiment, the annular plate 630 is rotated to connect the notch 631 on its outer side with the rectangular hole 570, thereby allowing the water inside the water tank 510 to flow into the detection chamber. When a suitable amount of water is collected inside the detection chamber, the annular plate 630 is rotated again to stagger the notch 631 with the rectangular hole 570, so that the annular plate 630 blocks the detection chamber, thereby facilitating centralized temperature adjustment of the water in the detection chamber. It should be noted that during the above working process, the detection chamber cannot be filled with water, because it is necessary to continue to pump high-temperature or low-temperature water into the detection chamber to adjust the overall water temperature of the water inside the detection chamber.

[0060] like Figure 7 and Figure 8 As shown, in this embodiment, the stirring mechanism 600 is arranged inside the detection cavity of the water bucket 500 at the corresponding position, and the stirring mechanism 600 includes a stirring shaft 610 rotatably connected to the water bucket 500, and two partitions 520 are respectively rotatably connected to the stirring shaft 610 at the corresponding positions, a tripod 611 is fixed at one end of the stirring shaft 610, and a motor 560 capable of driving the stirring shaft 610 to rotate is fixed at the top and bottom of the water bucket 500, and a plurality of paddles 620 are evenly fixed on the bottom surface of the tripod 611, wherein an annular plate 630 is fixed to the outer side of the plurality of paddles 620.

[0061] In this embodiment, the motor 560 drives the stirring shaft 610 to rotate, so that the notch 631 on the annular plate 630 first rotates to a position communicating with the rectangular hole 570, and then an appropriate amount of water is injected into the detection cavity. Then, the stirring shaft 610 drives the annular plate 630 to continue rotating through the paddle 620, so that the notch 631 is separated from the rectangular hole 570, and the annular plate 630 can block the rectangular hole 570, so that the water in the water tank 510 no longer flows into the detection cavity. On the premise that the annular plate 630 blocks the rectangular hole 570, the motor 560 can be driven to drive the stirring shaft 610 to rotate in a positive and negative cycle, so that the stirring shaft 610 drives a plurality of paddles 620 to rotate back and forth inside the detection cavity through the trident bracket 611, which is convenient for stirring and mixing the water inside the detection cavity, and is convenient for quickly mixing the cold water or hot water added to the detection cavity evenly.

[0062] As Figure 2 and Figure 4 shown, in this embodiment, a second water delivery pipe 700 is fixedly connected and communicated on the outer side of the drain pipe 370. The top of the second water delivery pipe 700 is fixedly connected and communicated with the cold water cavity. Valves are installed on the outer sides of both the drain pipe 370 and the second water delivery pipe 700. When it is necessary to transport the over-cooled standby water into the cooling cavity, the valve on the second water delivery pipe 700 is opened, and the valve on the drain pipe 370 is closed, which is convenient for transporting the over-cooled water to the cold water cavity for standby. During normal use, the valve on the second water delivery pipe 700 is closed, and the valve on the drain pipe 370 is opened, so that the heat-exchanged water directly flows into the water tank 510.

[0063] As Figure 1 and Figure 4 shown, in this embodiment, a third water delivery pipe 800 is fixedly connected and communicated on the outer side of the water inlet pipe 350. The bottom of the third water delivery pipe 800 is fixedly connected and communicated with two detection cavities. Two branch pipes are fixedly connected and communicated on the outer side of the third water delivery pipe 800. The two branch pipes are respectively fixedly connected and communicated with the corresponding detection cavities on the water bucket 500. Valves are installed on the outer sides of the branch pipes.

[0064] In this embodiment, when the valve on the branch pipe is opened, the waste water pumped into the water inlet pipe 350 can be directly transported to different detection cavities, so as to transport high-temperature waste water to different positions of the detection cavities to adjust the overall water temperature of the waste water inside the detection cavities. The above valves and the valves installed on the remaining pipes of this application can all be selected from the solenoid valves in the prior art to achieve automatic control. The valves are existing components, and the specific principle of opening and closing to block the water flow will not be elaborated.

[0065] As Figure 3 shown, in this embodiment, the base 100 is used to support and fix the entire heat exchanger. Among them, a motor 560 is fixedly embedded with the base 100.
