Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange in refrigeration systems, and specifically to a cylindrical finned coil air-cooled high-efficiency heat exchanger and a usage method thereof. Background Art

[0002] In recent years, with the continuous development of refrigeration and heat pump technologies as well as new energy, the efficiency and energy efficiency of refrigeration and heat pump systems have been continuously improved, and the application scope has been continuously expanded. Finned condensers, one of the main current applications, are in the fields of refrigeration and heat pumps. Due to problems such as large volume, large installation floor area, low energy efficiency, uneven air reception (suction) on the finned windward surface, even the existence of heat exchange blind spots, poor condensate water collection during liquid evaporation and easy overflow, which affect the surrounding environment and the service life of the equipment, the use of a cylindrical finned high-efficiency heat exchanger can solve the above technical problems.

[0003] The current traditional styles of finned coil air-cooled heat exchangers are rectangular side air outlet and V-shaped top air outlet. Due to their rectangular structures, both have large installation floor areas and require a lot of space reserved for air suction convection. The air reception (suction) on the finned windward surface is uneven, and the heat exchange efficiency is relatively low. To improve the heat exchange efficiency, it is necessary to increase the finned windward area and make the air volume passing through the fin pitch uniform, without heat exchange blind spots (that is, less or no ventilation in the fin pitch of some coils). The cylindrical finned high-efficiency heat exchanger forms a 360-degree windward contact surface in a circular shape, and then through the middle air guiding cone, under the suction of the top fan exhaust, air uniformly passes through the fin pitch of the coil, effectively increasing the area and air convection, and greatly improving the heat exchange efficiency. Summary of the Invention

There are a total of four groups of support columns. At the bottom ends of the opposite faces of the four groups of support columns, support crossbars are connected. A cleaning mechanism is provided at the top of the support crossbars. Surrounding plates are connected to the outside of the four groups of support columns, and a fan mounting plate is provided at the top of the four groups of support columns.

[0006] By adopting the above technical solution, the cylindrical finned coil heat exchanger is installed at the inner end of the sheet metal support housing, and the cylindrical finned coil heat exchanger can be protected by the sheet metal support housing.

[0007] Preferably, the cleaning mechanism includes a moving plate, a flapping mechanism, a synchronous plate and a driving mechanism. A moving plate is provided at the middle end of the bottom surface of each of the four support crossbars. A first chute is provided at the middle end of the bottom surface of each of the four support crossbars. A first slider corresponding thereto is provided at the bottom end of the moving plate.

And a driving mechanism is connected to the right rear end of the left support crossbar.

[0008] By adopting the above technical solution, the driving mechanism can drive the moving plate to move, and the movement of the moving plate can drive the flapping mechanism to move, so as to flap the enclosure and knock off the dust and impurities on the enclosure, avoiding the influence of dust accumulation on the air flow blockage.

[0009] Preferably, the components of the flapping mechanism are all the same. The flapping mechanism includes a connecting base, a first swing arm, a second swing arm, a flapping member and a linkage plate. Not less than two connecting bases are equidistantly provided at the top ends of the moving plates. A first swing arm is connected to the side of each connecting base close to the support crossbar. A second swing arm is connected to the top end of each first swing arm. A gear is connected to the middle outer side of the second swing arm. A flapping member is provided at the top end. And a linkage plate corresponding to the first swing arm is provided inside the support crossbar.

[0010] By adopting the above technical solution, the rotation of the first swing arm can drive the linkage plate to move up and down, and the rotation of the second swing arm can drive the flapping member to rotate synchronously.

[0011] Preferably, not less than two convex teeth are provided at the top end of the side of the linkage plate close to the second swing arm. The bottom end is connected to the first swing arm through a connecting shaft. Second chutes corresponding to the linkage plate are provided inside the support crossbars. A second slider corresponding to the second chute is provided on the side of the linkage plate close to the support crossbar.

[0012] By adopting the above technical solution, the rotation of the first swing arm drives the linkage plate to move up and down, and drives the gear and the second swing arm to rotate through the convex teeth.

[0013] Preferably, the driving mechanism includes an expansion chamber, a driving motor, a turntable, a first transmission arm, and a second transmission arm.

[0014] By adopting the above technical solution, the driving motor drives the turntable to rotate. The turntable drives the first transmission arm and the second transmission arm to move. Then, the second transmission arm pulls or pushes the moving plate to move, which can effectively improve the overall synchronous linkage.

[0015] Preferably, the cylindrical finned coil heat exchanger includes a cooling fan and a cylindrical finned coil. The cooling fan is connected to the top end of the fan mounting plate. The cylindrical finned coil is provided at the bottom end of the fan mounting plate. There is an opening in the front middle of the cylindrical finned coil. The inlet pipe is connected to the right end inside the opening through an air inlet flow equalizer. A set of outlet pipes are connected to the right end inside the opening. A set of condenser connection sealing plates are connected between the inlet pipe and the outlet pipe. A set of air guiding conical columns are provided at the inner end of the cylindrical finned coil. The bottom end of the air guiding conical column is connected to a set of circular bottom basins.

[0016] By adopting the above technical solution, the cooling fan can drive the air through the cylindrical finned coil. The inlet pipe and the air inlet flow equalizer can send the fluid into the cylindrical finned coil, and heat exchange is carried out on the fluid by the air.

[0017] Preferably, the sheet metal support housing and the cylindrical finned coil heat exchanger have a structure of square outside and round inside, that is, the housing is square and the internal is a cylindrical finned coil.

[0018] By adopting the above technical solution, the sheet metal support housing can protect the cylindrical finned coil and its external components.

[0019] Preferably, the cylindrical finned coil can be used for condensing high-temperature and high-pressure gas or evaporating high-pressure and low-temperature liquid. The inlet pipe sends the gas (or liquid) and the air inlet flow equalizer into the cylindrical finned coil through a multi-way shunt pipe for condensation (or evaporation) evenly. After the gas is condensed (or the liquid is evaporated), it flows out through the outlet pipe.

[0020] Preferably, the cylindrical finned coil is in the shape of a 0-degree cylinder. Forced convection is carried out by the top cooling fan. The air enters through the fin pitch and takes away the heat of the cylindrical finned coil.

[0021] The present application provides a method for using a cylindrical finned coil air-cooled high-efficiency heat exchanger, which includes the following steps: S1: Fluids can uniformly flow into the cylindrical finned coil through the intake pipe and the intake air flow equalizer via the multi-channel shunt pipe; S2: Drive the cooling fan to rotate, drive the air to flow into the cylindrical finned coil through the enclosing plate, and make the air uniformly pass through the coil pitch of the cylindrical finned coil through the air guiding conical column, so as to perform heat exchange on the fluids in the cylindrical finned coil; S3: The fluids that have completed heat exchange flow out through the liquid outlet pipe; S4: Drive the drive motor, the drive shaft rotates in one reverse direction, drive the turntable to rotate, and then drive the first transmission arm and the second transmission arm to rotate, and link the movement of the moving plates at the left end and the rear end; S5: The moving plates at the left end and the rear end drive the moving plates at the right end and the front end to move through the synchronization plate; S6: The movement of the moving plates drives the connection bases to move, and then drives the first swing arm and the second swing arm to rotate; S7: The rotation of the first swing arm drives the linkage plate to move, so that the gear on the outer side of the second swing arm contacts the convex teeth; S8: When the first swing arm and the second swing arm continue to rotate, the convex teeth drive the gear to rotate, and then drive the second swing arm to rotate; S9: The rotation of the second swing arm can drive the flapping member to rotate, flap the enclosing plate, and knock off the impurities on the enclosing plate; S10: The drive shaft of the drive motor rotates in the other direction, and drives components such as the moving plates, the first swing arm, the second swing arm, the flapping member and the linkage plate to reset, completing a cleaning operation.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By adopting a cylindrical top air outlet structure in the present application, different from the traditional rectangular side air outlet condenser, V-shaped top air outlet condenser and L-shaped top air outlet condenser, since the traditional rectangular condenser must reserve the heat dissipation convection distance for air intake and air outlet, the installation area occupied by the traditional heat exchanger is much larger. The cylindrical structure greatly reduces the length compared with the traditional rectangular condenser, and the convective air of the cylindrical finned coil heat exchanger is discharged from the top. Therefore, only the air intake distance around the cylinder (or whether there is space for fresh air replenishment) needs to be considered. Therefore, the installation of the cylindrical finned coil air-cooled high-efficiency heat exchanger greatly saves the installation area; 2. By using a cylindrical finned coil heat exchanger in this application, the cylindrical finned coil air-cooled high-efficiency heat exchanger has a windward surface on all 360 degrees, solving the blind spots and dead corners of convection in traditional heat exchangers. Under the suction of the exhaust of the top cooling fan, the air guide conical column in the middle of the cylindrical finned coil heat exchanger allows the air inhaled by the cooling fan to evenly pass through the coil fin pitch, greatly improving the heat exchange efficiency. 3. Through the cleaning mechanism installed on the support crossbar, the cleaning mechanism includes components such as a moving plate, a flapping mechanism, a synchronous plate, and a driving mechanism. With their mutual cooperation, the driving mechanism can drive the moving plate to move, and the flapping mechanism on the moving plate can be linked to flap the surrounding plate, knocking off the dust and impurities on the surrounding plate, preventing the surrounding plate from blocking the ventilation holes and affecting the air flow.

Detailed Embodiment

[0025] In order to further explain the technical solution of the present invention, it will be elaborated in detail through specific embodiments below.

A cleaning mechanism 13 is provided at the top end of the support crossbar 12. Surrounding plates 14 are installed on the outer sides of the four groups of support columns 11. Ventilation holes are provided on the surface of the surrounding plate 14, which is beneficial to the flow of air through. The fan mounting plate 15 is installed at the top ends of the four groups of support columns 11.

[0027] Specifically, the cylindrical finned coil heat exchanger 2 is installed at the inner end of the sheet metal support housing 1, and their structures are square outside and round inside. The cylindrical finned coil heat exchanger 2 can be protected by the sheet metal support housing 1.

[0028] Please refer to Figures 2 - 4 , the cleaning mechanism 13 includes a moving plate 131, a beating mechanism 132, a synchronous plate 133 and a driving mechanism 134. A moving plate 131 is slidably connected to the middle of the bottom surface of each of the four groups of support crossbars 12. A first chute 1311 is provided in the middle of the bottom surface of each of the four groups of support crossbars 12. A first slider 1312 corresponding to it is fixedly connected to the bottom end of the moving plate 131. The moving plate 131 can reciprocate through the first chute 1311 and the first slider 1312. At least two groups of beating mechanisms 132 are equally spacedly installed at the top ends of the moving plates 131. And the front moving plate 131 and the left moving plate 131, the rear moving plate 131 and the right moving plate 131 are connected by a synchronous plate 133. The movement of the front moving plate 131 and the rear moving plate 131 can drive the movement of the left moving plate 131 and the right moving plate 131, and vice versa. And a driving mechanism 134 is connected to the right rear end of the left support crossbar 12.

[0029] Specifically, the driving mechanism 134 can drive the rear moving plate 131 and the left moving plate 131 to move, and drive the front moving plate 131 and the right moving plate 131 to move through the synchronous plate 133. At the same time, the movement of the moving plate 131 can drive the beating mechanism 132 to move.

[0030] Please refer to Figures 3 - 4, the components of the flapping mechanism 132 are all the same. The flapping mechanism 132 includes a connecting base 1321, a first swing arm 1322, a second swing arm 1323, a flapping member 1324 and a linkage plate 1325. At least two groups of connecting bases 1321 are fixedly connected to the top end of the moving plate 131 at equal intervals. One group of first swing arms 1322 is hinged to the side of each connecting base 1321 close to the support cross bar 12. One group of second swing arms 1323 is rotatably connected to the top end of each first swing arm 1322. A group of gears 13231 is fixedly connected to the outer middle end of each second swing arm 1323, and a group of flapping members 1324 is fixedly connected to the top end. And a linkage plate 1325 corresponding to the first swing arm 1322 is slidably connected to the inner side of the support cross bar 12.

[0031] Specifically, the rotation of the first swing arm 1322 can drive the linkage plate 1325 to move up and down, and the rotation of the second swing arm 1323 can drive the flapping member 1324 to rotate synchronously.

[0032] Please refer to Figures 3 - 5 , on the top end of the side of the linkage plate 1325 close to the second swing arm 1323, there are at least two groups of convex teeth 13251. The convex teeth 13251 are arranged in an arc shape and can be engaged with the gear 13231. Among them, when the top end of the second swing arm 1323 and the flapping member 1324 rotate and extend to the top end of the support cross bar 12, the gear 13231 contacts the convex teeth 13251, which can prevent the flapping member 1324 from rotating in advance and hitting the support cross bar 12, causing damage. The bottom end of the side of the linkage plate 1325 close to the second swing arm 1323 is rotatably connected to the first swing arm 1322 through a connecting shaft 13252. When the first swing arm 1322 rotates, the linkage plate 1325 can be driven to move up and down by the connecting shaft 13252. Slide grooves two 13253 corresponding to the linkage plate 1325 are opened on the inner sides of the support cross bars 12. A slider two 13254 corresponding to the slide groove two 13253 is arranged on the side of the linkage plate 1325 close to the support cross bar 12, which can limit the moving path of the linkage plate 1325 and improve the stability during movement.

[0033] Specifically, the rotation of the first swing arm 1322 drives the linkage plate 1325 to move up and down, and drives the gear 13231 and the second swing arm 1323 to rotate through the convex teeth 13251.

[0034] Please refer to Figure 2 And Figure 6, the drive mechanism 134 includes an expansion chamber 1341, a drive motor 1342, a turntable 1343, a first transmission arm 1344 and a second transmission arm 1345. The right rear end of the left end support cross bar 12 is fixedly connected to the expansion chamber 1341. The back of the expansion chamber 1341 is attached to the front left end of the rear end support cross bar 12, reducing the occupation of space. And a set of drive motors 1342 are installed in the middle of the expansion chamber 1341. The top end of the drive shaft of the drive motor 1342 penetrates and extends to the top of the expansion chamber 1341 and is connected to a set of turntables 1343, which can drive the turntable 1343 to rotate. A set of first transmission arms 1344 are fixedly connected to the rear end and the left end of the turntable 1343. The other ends of the two sets of first transmission arms 1344 are respectively connected to the left end moving plate 131 and the rear end moving plate 131 through a set of second transmission arms 1345. When the turntable 1343 rotates, it can drive the left end moving plate 131 and the rear end moving plate 131 to move respectively through the two sets of first transmission arms 1344 and the second transmission arms 1345.

[0035] Specifically, the drive motor 1342 drives the turntable 1343 to rotate. The turntable 1343 drives the first transmission arm 1344 and the second transmission arm 1345 to move. Then, the second transmission arm 1345 pulls or pushes the moving plate 131 to move, which can effectively improve the overall synchronous linkage.

And multiple small pipes are welded on the air inlet flow equalizer 222, which can send the fluid into the cylindrical finned coil 22. A set of liquid outlet pipes 223 are connected to the right end inside the opening, which can discharge the fluid. Among them, the inlet pipe 221 and the liquid outlet pipe 223 can be interchanged in the left-right direction according to the installation needs. And a set of condenser connection sealing plates 224 are installed between the inlet pipe 221 and the liquid outlet pipe 223 to fill the gap between them. A set of air guiding conical columns 225 are provided in the middle of the cylindrical finned coil 22. The bottom diameter and height of the air guiding conical column 225 are made based on the inner diameter and height of the cylindrical finned coil 22 as the technical basis, which can guide the air to flow evenly through the cylindrical finned coil 22. The bottom end of the air guiding conical column 225 is connected to a set of circular bottom basins 226. The size of the circular bottom basins 226 is made according to the circular outer diameter of the cylindrical finned coil 22, which can meet the collection of the condensed liquid.

[0037] Specifically, the cooling fan 21 can drive air to pass through the cylindrical finned coil 22. The intake pipe 221 and the intake flow equalizer 222 can send the fluid into the cylindrical finned coil 22, and heat exchange is carried out on the fluid through the air.

[0038] Please refer to Figure 2 , the cylindrical finned coil 22 can be used for condensing high-temperature and high-pressure gas or evaporating high-pressure and low-temperature liquid. The intake pipe 221 sends the gas or liquid and the intake flow equalizer 222 into the cylindrical finned coil 22 evenly through the multi-way shunt pipe for condensation or evaporation. After the gas is condensed or the liquid is evaporated, it flows out through the liquid outlet pipe 223.

[0039] Specifically, the applicability of the present application can be improved to meet different usage requirements.

[0041] This application provides a cylindrical finned coil air-cooled high-efficiency heat exchanger and its usage method. By adopting a cylindrical top air outlet structure, it is different from traditional rectangular side air outlet condensers, V-shaped top air outlet condensers, and L-shaped top air outlet condensers. Since the traditional rectangular condenser must reserve the heat dissipation convection distance for air intake and outlet, the installation area occupied by the traditional heat exchanger is much larger. The cylindrical structure significantly reduces the length compared to the traditional rectangular condenser. Moreover, the convective air of the cylindrical finned coil heat exchanger 2 is discharged from the top, so only the air intake distance around the cylinder (or whether there is space for fresh air replenishment) needs to be considered. Therefore, the installation of the cylindrical finned coil air-cooled high-efficiency heat exchanger greatly saves the installation area. By using the cylindrical finned coil heat exchanger 2, the cylindrical finned coil air-cooled high-efficiency heat exchanger has a windward surface on all 360 degrees, solving the blind spots and dead corners of convection in traditional heat exchangers. Under the suction of the exhaust fan at the top, the air guide cone column in the middle of the cylindrical finned coil heat exchanger allows the air inhaled by the cooling fan 21 to evenly pass through the coil fin pitch, greatly improving the heat exchange efficiency. Through the cleaning mechanism 13 installed on the support crossbar 12, the cleaning mechanism 13 includes components such as a moving plate 131, a flapping mechanism 132, a synchronization plate 133, and a driving mechanism 134. With their mutual cooperation, the driving mechanism 134 can drive the moving plate 131 to move, and the flapping mechanism 132 on the moving plate 131 can be linked to flap the enclosure 14, knocking off the dust and impurities on the enclosure 14, preventing the enclosure 14 from blocking the ventilation holes and affecting the air flow.
