Description
Technical Field
[0001] This invention relates to the field of motor cooler technology, specifically to an oxidation fan motor cooler. Background Technology
[0002] In actual operation, the operating temperature of the oxidation blower motor windings can reach 130℃. To prevent overheating, the manhole plate of the oxidation blower motor is removed. At this time, the motor is in a semi-open operation. When the equipment is stopped (on standby), humid air will condense on the iron core and windings, making the insulation susceptible to moisture and reducing its strength. The running equipment will draw dust from the air into the chamber, causing dust accumulation on the winding insulation, which makes the motor more susceptible to moisture. If a short circuit fault occurs in the semi-open motor, the short circuit arc will be ejected from the manhole plate, posing an inherent safety hazard.
[0003] Existing built-in coolers come in two types: air-cooled and water-cooled. Air-cooling has limited heat dissipation and air exchange still occurs between the inside and outside of the motor, making it susceptible to short-circuit faults such as dust accumulation and moisture buildup inside the motor. Furthermore, when conventional water-cooling devices are installed inside the motor, condensation on the surface of the condenser tubes can easily cause water droplets to form, leading to motor corrosion.
[0004] Based on this, the present invention designs an oxidation fan motor cooler to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide an oxidation fan motor cooler that uses negative pressure suction and condensation components to form directional forced convection, quickly removing heat from the motor housing while keeping the motor completely enclosed.
[0006] To achieve the above objectives, the present invention provides the following technical solution: An oxidation blower motor cooler includes a mounting frame, one end of which is a rectangular frame, and the other end is connected to a condenser assembly. The mounting frame can be horizontally mounted across the oxidation blower motor. The rectangular frame and the condenser assembly are located on opposite sides of the motor and are parallel to each other, forming a double-sided convection cooling structure. The condenser assembly includes: The condenser tube and the condenser are connected in series at both ends of the condenser tube via a circulation pipe assembly. Each circulation pipe assembly is fixedly mounted with an mounting plate. The two sets of mounting plates are arranged parallel to each other. Multiple condenser tubes are arranged parallel to each other at equal intervals and are rotatably connected between the two sets of mounting plates. A driving structure is provided inside the mounting plate, which can drive the condenser tube to rotate. The absorbent cloth is disposed between adjacent condenser tubes via a traction structure, which can pull the absorbent cloth to move back and forth between the gaps in the condenser tubes.
[0007] Preferably, the upper mounting plate is fixedly connected to the mounting frame, the mounting plate has multiple sets of mounting chambers, both ends of the condenser tube are fixedly installed with connecting ends, the connecting ends penetrate the mounting chambers longitudinally, and the ends are located on the other side of the mounting plate, the driving structure is disposed in the mounting chambers, and the driving structure can drive the connecting ends to rotate.
[0008] Preferably, the circulation pipe group is provided with multiple sets of branch pipes, and an upper connecting pipe is fixedly installed at the end of each set of branch pipes. The upper connecting pipe is rotatably connected to the connecting end, and multiple sets of support claws are fixedly installed on the outside of the upper connecting pipe. The support claws are fixedly connected to the surface of the mounting plate.
[0009] Preferably, the upper and lower sets of mounting plates are connected by a positioning frame. The side positioning frame is a U-shaped frame and its position corresponds one-to-one with the position of the condenser pipe. The absorbent cloth is located between adjacent condenser pipes, and its two ends are respectively fixed on the adjacent side positioning frame.
[0010] Preferably, the traction structure includes a movable guide rod, an extension rod, a movable plate, and a telescopic cylinder. The telescopic cylinder is fixedly mounted on the mounting plate, and its output end is fixedly connected to the movable plate. The mounting plate has sliding grooves on the side near the condenser pipe, corresponding to the middle position of the gap between the condenser pipes. The upper and lower ends of the movable guide rod are provided with sliders, which are slidably connected in the sliding grooves. The extension rod is fixedly connected between the sliders and the movable plate.
[0011] Preferably, a fan frame is fixedly installed within the rectangular frame by bolts, and a negative pressure fan is fixedly installed on the fan frame. The negative pressure fan can drive air to flow from the condenser assembly toward the negative pressure fan.
[0012] Preferably, the absorbent cloth is elastic, and a temperature sensor and a control module are provided on the crossbeam of the mounting frame. The temperature sensor can detect the temperature of the oxidation fan motor, and the control module can regulate the power of the negative pressure fan and the condenser.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention cools the airflow by passing it through a condenser assembly, where the condenser tubes within the assembly cool the airflow. This allows the low-temperature gas to flow over the surface of the motor housing, exchanging heat with the motor and achieving cooling. During the cooling process, the motor remains completely sealed, thus preventing the possibility of short-circuit faults due to dust accumulation or moisture inside the motor. Furthermore, compared to traditional direct air-cooling equipment, this invention first cools the gas with water before allowing the low-temperature airflow to flow to the motor housing, thereby improving the motor's heat dissipation effect.
[0015] 2. In this invention, an absorbent cloth is installed between the condenser tubes. By moving back and forth between the condenser tubes and combining it with the rotation of the condenser tubes themselves, the absorbent cloth can quickly absorb the water droplets condensed on the surface of the condenser tubes. On the one hand, this prevents water from seeping into the motor housing with the airflow. On the other hand, it prevents the accumulation of condensed water droplets, which would cause corrosion of the condenser tubes and increase their service life. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see Figures 1-5 The present invention provides a technical solution: An oxidation blower motor cooler includes a mounting frame 1. One end of the mounting frame 1 is a rectangular frame, and the other end is connected to a condenser assembly. The mounting frame 1 can be horizontally mounted on the oxidation blower motor. The rectangular frame and the condenser assembly are located on opposite sides of the motor and are parallel to each other, forming a double-sided convection cooling structure. The condenser assembly includes: The condenser 5 and the condenser 3 are connected in series at both ends of the condenser 5 through the circulation pipe group 4. Each of the circulation pipe group 4 is fixedly installed with an installation plate 11. The two sets of installation plates 11 are arranged in parallel vertically. Multiple condenser 5 are arranged in parallel at equal intervals and are rotatably connected between the two sets of installation plates 11. The installation plate 11 is provided with a driving structure that can drive the condenser 5 to rotate. The absorbent cloth 7 is installed between adjacent condenser pipes 5 by a traction structure. The traction structure can pull the absorbent cloth 7 to move back and forth between the gaps of the condenser pipes 5.
[0021] In this invention, a negative pressure fan is bolted into the rectangular frame. The airflow direction is: condenser assembly → motor surface → negative pressure fan. Negative pressure suction creates directional forced convection, quickly removing heat from the motor housing. The airflow passes through the condenser assembly, where the condenser tubes 5 cool it. This allows the low-temperature gas to flow over the motor housing surface, exchanging heat with the motor and completing the cooling process. During cooling, the motor remains completely sealed, preventing potential short-circuit faults due to dust accumulation or moisture inside the motor. Furthermore, compared to traditional direct air-cooling equipment, water cooling is applied first before the low-temperature airflow reaches the motor housing, improving heat dissipation. A water-absorbing cloth 7 is placed between the condenser tubes 5. The cloth 7 moves back and forth between the tubes, and combined with the rotation of the tubes, quickly absorbs condensed water droplets on the surface of the tubes. This prevents water from seeping into the motor housing with the airflow and also prevents condensed water droplets from accumulating and corroding the tubes, increasing their lifespan.
[0022] The upper mounting plate 11 is fixedly connected to the mounting frame 1. Multiple mounting chambers 14 are formed on the mounting plate 11. Connecting ends 13 are fixedly installed at both ends of the condenser pipe 5. The connecting ends 13 longitudinally penetrate the mounting chambers 14, with their ends located on the other side of the mounting plate 11. A driving structure is located inside the mounting chambers 14 and can drive the connecting ends 13 to rotate. In this invention, the condenser pipe 5 is rotatably connected to the mounting plate 11 via the connecting ends 13. The rotation of the connecting ends 13 drives the condenser pipe 5 to rotate. The driving structure is located inside the mounting plate 11 and is not directly exposed to the air, reducing the possibility of wear and tear on the transmission structure due to dust interference and increasing its service life.
[0023] The circulation pipe assembly 4 is provided with multiple sets of branch pipes, and each set of branch pipes is fixedly installed with an upper connecting pipe 8 at its end. The upper connecting pipe 8 is rotatably connected to the connecting end 13. Multiple sets of support brackets are fixedly installed on the outside of the upper connecting pipe 8, and the support brackets are fixedly connected to the surface of the mounting plate 11. In this invention, the multiple sets of branch pipes of the circulation pipe assembly 4 are connected to the connecting end 13, and the main pipe is connected to the condenser 3. The condenser 3 cools the condensate. After cooling, the low-temperature condensate is output through the lower circulation pipe assembly 4 and enters the condenser pipe 5 through the multiple sets of connecting ends 13. After heat exchange with the airflow in the condenser pipe 5, the condensate moves upward and flows back to the condenser 3 from the upper circulation pipe assembly 4 for cooling again.
[0024] The upper and lower mounting plates 11 are connected by positioning frames 6. The side positioning frames 6 are U-shaped and correspond one-to-one with the positions of the condenser pipes 5. The absorbent cloth 7 is located between adjacent condenser pipes 5, and its two ends are fixed to the adjacent side positioning frames 6 respectively. In the normal state of this invention, the absorbent cloth 7 is spread out between the two sets of side positioning frames 6. At this time, when the airflow flows through the condenser assembly to the negative pressure fan on the rectangular frame, the airflow can dry the absorbent cloth 7 to a certain extent, so that the absorbent cloth 7 can be recycled, and also allows the absorbent cloth to exchange heat with the airflow to a certain extent, so as to make full use of energy.
[0025] The traction structure includes a movable guide rod 10, an extension rod 15, a movable plate 9, and a telescopic cylinder. The telescopic cylinder is fixedly mounted on the mounting plate 11, and its output end is fixedly connected to the movable plate 9. The mounting plate 11 has sliding grooves 12 at the midpoint of the gap between the condenser pipes 5 on the side closest to the condenser pipes 5. The movable guide rod 10 has sliders at both its upper and lower ends, which are slidably connected within the sliding grooves 12. The extension rod 15 is fixedly connected between the sliders and the movable plate 9. In this invention, the telescopic cylinder extends, pushing the movable plate 9 away from the mounting plate 11, thereby pulling the movable guide rod 10 to move within the sliding grooves 12 via the extension rod 15. The movable guide rod 10 moves, pulling the absorbent cloth 7 into the gap between the condenser pipes 5. The absorbent cloth 7, under elastic action, covers the surface of the condenser pipes 5.
[0026] Within the rectangular frame, a fan frame 2 is fixedly mounted with bolts. A negative pressure fan is fixedly mounted on the fan frame 2, and the negative pressure fan drives air to flow from the condenser assembly towards the negative pressure fan. In this invention, the airflow is driven by a negative pressure fan.
[0027] The absorbent cloth 7 is elastic, and a temperature sensor and a control module are installed on the crossbeam of the mounting frame 1. The temperature sensor can detect the temperature of the oxidation fan motor, and the control module can regulate the power of the negative pressure fan and the condenser 3. In this invention, the motor temperature is detected by the control module and the temperature sensor, and the working power is increased when the temperature is high.
[0028] The drive structure consists of a micro motor and two sets of transmission gears. The micro motor is fixedly installed inside the mounting chamber 14, and the two sets of transmission gears mesh with each other. One set of transmission gears is fixedly connected to the connecting end 13, and the other set of transmission gears is fixedly connected to the output end of the micro motor. In this invention, the rotation of the micro motor drives the transmission gears to rotate, and the meshing action of the rotating gears drives the connecting end 13 to rotate, thereby driving the condenser tube 5 to rotate.
