Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a rotary evaporative condenser. Background Art

[0002] Evaporative condensers are involved in nearly 30 industries such as HVAC, pressure vessels, reclaimed water treatment equipment, chemicals, and petroleum. They are a commonly used refrigeration equipment. Their principle is to use the temperature difference between the cooling medium and the cooled medium to exchange heat and mass through a heat exchanger to cool or condense the cooled medium.

[0003] The working process of the condenser is an exothermic process, so the condenser temperature is relatively high. Therefore, when the condenser fails, the condenser needs to be ventilated as soon as possible to reduce its temperature to ensure the safety of the equipment.

By mounting the condensing device on the rotating platform and making the rotating platform rotate along the rotating track, when a fire or other emergency occurs, the motor drives the rotating platform to rotate on the rotating track through the transmission mechanism, thereby driving the condensing device to rotate a certain angle to make way for ventilation and smoke exhaust.

[0005] In this structure, the motor drives the rotating platform, which in turn drives the condensing device to rotate. The motor output shaft needs to bear the weight of the rotating platform and the condensing device, and the load on the motor output shaft is relatively high. Excessive load may cause unstable operation of the motor, and long-term operation under heavy load will increase the wear and heat of the motor, resulting in a shortened motor life.

[0016] As a preferred embodiment of the present invention, the power structure is provided with heat dissipation fins.

[0017] Beneficial effects of the utility model:

[0018] 1. In the present application, the condensing device can be rotatably arranged. First, by rotating the condensing device, the blocking area of ​​the ventilation path of the airflow channel by the condensing device can be reduced, and the unobstructed ventilation area in the airflow channel can be increased, which facilitates ventilation between the condensing device and the airflow channel, and can achieve rapid heat discharge in the event of a fire.

[0019] Second, the operating principle of the condensing device is: the water distribution spray parts spray water on the packing, and the airflow takes away the heat of the water film on the surface of the packing, reducing the water temperature; the water with reduced temperature enters the heat exchanger for heat exchange, and the airflow also passes through the surface of the heat exchanger, and the water evaporates and exchanges heat under the forced drive of the airflow; by rotating the condensing device, the heat exchange effect of the airflow on the water film on the surface of the packing can be adjusted, and then the heat exchange effect of the water on the heat exchanger can be adjusted, and the heat exchange effect of the airflow on the heat exchanger can also be adjusted. Based on this, in the season when it is about to freeze, the condensing device can be rotated to reduce the airflow passing through the condensing device itself, thereby increasing the water temperature in the condensing device and avoiding the freezing of water in the condensing device and affecting the realization of the heat exchange function.

[0020] Third, by rotating the condensing device, the surface of the condensing device originally facing the wind forms an angle with the vent of the air flow channel, making it easy to clean the dust and impurities attached to the original windward surface of the condensing device by tools.

[0021] The condenser of the present application can be used in data centers, electrical equipment rooms and other air conditioning fields as well as petrochemical and other fields.

[0022] Among them, the condensing device is rotated and pushed by a driving device, and the driving device applies external force to the condensing device through the linkage action of the guide block and the hinged rod to drive the condensing device which is already movably arranged to rotate; according to the principle of torque, the farther the part where the external force is applied to the condensing device is relative to the rotation center axis of the condensing device, the smaller the applied external force can be; therefore, the condensing device is pushed to rotate without providing a large external force or bearing a large load as in the prior art, and the driving device has a long service life and is simple and effective to use.

[0023] 2. In an optional embodiment of the present application, two condensation devices are arranged in the shell to improve the condensation effect; at the same time, the two condensation devices are symmetrically arranged with the guide part as the center, which can balance the force on the guide part, improve the sliding stability of the guide block, and improve the service life of the pushing drive device.

[0024] 3. In an optional embodiment of the present application, the condensing device is connected to the rotating column and overlapped on the support portion, and the weight of the condensing device is distributed on the rotating column and the support portion; compared with the embodiment in which the condensing device is completely connected to the rotating column, the load on the rotating column is reduced to improve the rotation performance of the rotating column; compared with the embodiment in which the condensing device is completely overlapped on the support portion, the friction between the condensing device and the support portion is reduced to improve the rotation performance of the condensing device.

[0025] 4. In an optional implementation of the present application, a wind device is added. When the condensing device is working normally, it can be used to remove the heat of the filler and the water film on the surface of the heat exchanger to improve the heat exchange efficiency; when the condensing device is rotated for maintenance, the ventilation and heat removal efficiency can be improved.

[0026] 5. In an optional embodiment of the present application, a filter plate is arranged in the air flow channel to prevent debris and reduce dust from entering the air flow channel, thereby reducing scaling problems on the surface of the condensing device; a rotatable filter plate is further arranged to facilitate cleaning of the filter plate and provide a larger ventilation area for the air flow channel, thereby improving ventilation and heat dissipation efficiency.

DETAILED DESCRIPTION

[0031] The following are specific implementations of the present invention, and in conjunction with the accompanying drawings, the technical solution of the present invention is further described, but the present invention is not limited to these embodiments.

[0032] A rotary evaporative condenser, such as Figure 1 and Figure 2 As shown, it includes an air flow channel 1, a condensing device 2 and a driving device 3 arranged in the air flow channel 1.

[0033] The airflow channel 1 refers to a structure having two opposite openings, the two openings being connected so that the airflow can flow from one opening to the other opening. Figure 1 As shown, a hollow shell is provided, and an air inlet and an air outlet are respectively provided on a pair of opposite sides of the shell, and the other pair of opposite sides are closed, so that the airflow can flow from the air inlet through the inner cavity of the shell to the air outlet, so that the shell forms an airflow channel 1. The airflow flows in the airflow channel 1, and the device in the airflow channel 1 can be ventilated and cooled. The bottom surface of the shell is closed, and the top surface of the shell can be closed or provided with an openable and closable opening to improve the heat dissipation efficiency.

[0034] In some embodiments, a filter plate 12 may be provided at the air inlet of the air flow channel 1 alone, or at both the air inlet and the air outlet, to reduce impurities in the air flow entering the air flow channel 1 and reduce scaling of devices in the air flow channel 1 .

[0035] The filter plate 12 may be fixedly installed or movably installed. In some embodiments, the filter plate 12 realizes filtering and separation through fine mesh holes, which may affect the flow efficiency of the airflow. Figure 2 As shown, the filter plate 12 is rotatably installed at the air inlet, that is, the two opposite ends of the filter plate 12 are rotatably connected to the inner wall of the air flow channel 1. The rotational connection method is not limited. In some embodiments, a connecting shaft is set at the end of the filter plate 12, and the connecting shaft is connected to the sleeve through a rotating bearing, and then the sleeve is installed to the inner wall of the air flow channel 1. When the filter plate 12 is rotated to the point where the plate surface is parallel to the plane where the air inlet is located, a number of filter plates 12 cover the air inlet, and the filtering effect is achieved while allowing the air flow to pass through; when the filter plate 12 is rotated to the point where there is an angle between the plate surface and the plane where the air inlet is located, preferably a right angle, an unobstructed channel is formed between two adjacent filter plates 12, thereby improving the ventilation and heat removal efficiency.

[0036] The condensing device 2 is installed in the air flow channel 1. The condensing device 2 is an overall cubic structure with a pair of long side surfaces and a pair of short side surfaces, wherein the pair of long side surfaces respectively form the air inlet surface and the air outlet surface of the condensing device 2.

[0037] When the condensing device 2 is working, the air inlet and air outlet are parallel to the vents of the airflow channel 1, that is, the air inlet and air outlet of the shell. Therefore, the condensing device 2 almost completely blocks the ventilation path of the airflow channel, so that the airflow needs to pass through the air inlet of the airflow channel 1, the air inlet surface of the condensing device 2, the condensing device 2 itself, the air outlet surface of the condensing device 2, and the air outlet of the airflow channel 1 in sequence. The purpose of this setting is also to accelerate the heat exchange of the condensing device 2. Of course, based on the need for the subsequent rotation of the condensing device 2, there will be a gap between the short side of the condensing device 2 and the closed side of the airflow channel 1, and a small part of the airflow will flow directly in the gap.

[0038] When the condensing device 2 is shut down for maintenance or when a fire occurs, although the condensing device 2 and the gap can also allow air to pass through, the ventilation efficiency is relatively low. In order to accelerate ventilation and heat dissipation in this case, it is necessary to drive the condensing device 2 to rotate through the driving device 3 so that the air inlet surface is no longer parallel to the air inlet, reduce the blocking area of ​​the long side of the condensing device 2 facing the air flow channel, increase the area of ​​the gap, and thus improve the ventilation and heat removal efficiency between the condensing device 2 and the shell. It is preferred to rotate the short side of the condensing device 2 to be parallel to the air inlet of the air flow channel 1, so that the blocking area of ​​the ventilation path of the air flow channel 1 is minimized and the ventilation efficiency is maximized. In order to drive the rotation of the condensing device 2, in this application, the condensing device 2 is first rotatably arranged in the air flow channel 1, so that as long as a certain external force is applied to the condensing device 2, the condensing device 2 can be driven to rotate around its rotation center axis.

[0039] The specific setting method of the condensing device 2 is not limited. In some embodiments, a tray can be set in the airflow channel 1, and the bottom surface of the tray is rotatably connected to the bottom of the airflow channel 1 through a rotating bearing. The condensing device 2 is installed on the tray. In this method, the load requirements for the tray and the rotating bearing on the bottom of the tray are relatively high.

[0040] In other embodiments, Figure 2 As shown, a rotating column 5 is arranged in the air flow channel 1, and the two ends of the rotating column 5 are respectively connected to the inner top and the inner bottom of the air flow channel 1 through a rotating bearing, so that the rotating column 5 is rotatable. Then the condensing device 2 is connected to the rotating column 5, and the connection position and connection method of the condensing device 2 and the rotating column 5 are not limited. In some embodiments, in order to avoid damage to the overall structure of the condensing device 2, the condensing device 2 is connected to the rotating column 5 through its long side side, specifically, a mounting plate whose length direction is parallel to the axial direction of the rotating column 5 is fixedly arranged on the long side side of the condensing device 2 by screws or welding; a plurality of connecting members are arranged on the rotating column 5 along the axial direction, and the connecting member includes a connecting plate, and a card plate arranged on the connecting plate, and the card plate is provided with an arc groove, and the arc groove The curvature is consistent with the surface curvature of the rotating column 5, so that the card plate can be clamped on the rotating column 5, and then the card plate and the rotating column 5 are welded together to complete the connection between the connecting member and the rotating column 5; then the connecting plate of the connecting member and the mounting plate are fixedly connected by a plurality of screws, and the connection between the rotating column 5 and the condensing device 2 can be completed, so that the condensing device 2 rotates with the rotating column 5 as the central axis. Among them, the rotating column 5 can be connected to any part of the long side surface of the condensing device 2. In some embodiments, the end edge portion of the long side surface is connected to the rotating column 5; in other embodiments, the central portion of the long side surface is connected to the rotating column 5; considering the area required for the rotation of the condensing device 2, the latter embodiment is preferred.

[0041] On the basis of using the rotating column 5 to realize the rotatable condensing device 2, considering the weight of the condensing device 2, in some embodiments, a support portion 11 for supporting the condensing device 2 may be further provided at the inner bottom of the airflow channel 1, that is, the lower portion of the condensing device 2 includes an overlapping portion overlapped with the support portion 11. The condensing device 2 is doubly supported by the rotating column 5 and the support portion 11, and the weight of the condensing device 2 is dispersed on the rotating column 5 and the support portion 11, thereby reducing the load of the rotating column 5 and ensuring the rotation performance of the rotating column 5.

[0042] After the rotatable condensing device 2 is set, in order to drive the condensing device 2 to rotate, in the present application, an external force is then applied to the condensing device 2 through the driving device 3.

[0043] According to the principle of torque, the farther the force is from the central axis of rotation, the smaller the force is. The central axis of rotation is constant, so the force application point is usually fixed; and because the condensing device 2 is rotatable, the driving device 3 needs to be adjusted with the position of the condensing device 2 to always apply force to the force application point. Therefore, the structure of the driving device 3 is specifically set: Figure 3 As shown, the driving device 3 includes a guide portion 31, a guide block 32, a hinged rod 33, and a power structure 34. The guiding direction of the guide portion 31 is perpendicular to the axial direction of the rotation center axis of the condensing device 2, and the power structure 34 drives the guide block 32 to slide along the guiding direction of the guide portion 31; one end of the hinged rod 33 is hinged to the condensing device 2, and the other end is hinged to the guide block 32. The power structure 34 provides force, and the direction of the force is changed by the hinge action to achieve the pushing of the condensing device 2. Specifically, according to Figure 2 In the direction, the guiding direction of the guide part 31 is the front-to-back direction. When the guide block 32 slides forward, the end of the left hinged rod 33 hinged to the guide block 32 also moves forward, so that the hinged rod 33 rotates counterclockwise, and the end of the hinged rod 33 hinged to the condensing device 2 moves to the left, thereby giving the condensing device 2 a force pushing to the left, driving the condensing device 2 to rotate counterclockwise.

[0044] Based on the above, the condensing device 2 is rotated and the driving device 3 plays a driving role, so that the condensing device 2 can be pushed and rotated, and can be pushed open in time in case of fire to achieve rapid heat discharge.

[0045] In the above structure, the setting of the guide portion 31 is not limited, and the guide portion 31 can only refer to one direction or a specific structure, preferably a specific structure to improve the guiding accuracy. In some embodiments, the guide portion 31 is a bar block fixedly installed on the top of the air flow channel 1, and a slide groove is provided on the side of the bar block along the length direction, and the guide block 32 is slidably set in the slide groove.

[0046] The setting of the power structure 34 is not limited. In some embodiments, the power structure 34 is a cylinder or oil cylinder connected to the piston rod and the guide block 32, and the linear telescopic movement of the piston rod drives the guide block 32 to slide along the guide direction. In other embodiments, the power structure 34 is a ball screw, which is a structure commonly used in the prior art to convert rotary motion into linear motion. When the ball screw is used as the active body, the nut will be converted into linear motion according to the lead of the corresponding specification as the rotation angle of the screw rod, and the passive workpiece can be connected to the nut through the nut seat, thereby realizing the corresponding linear motion. By connecting the guide block 32 with the nut of the ball screw, the guide block 32 can be driven to slide along the guide direction under the rotation of the ball screw. In addition, in some other embodiments, a heat dissipation fin 341 is provided on the power structure 34 to prevent the power structure 34 installed near the condensing device 2 from being overheated and damaged.

[0047] The force application point, i.e., the hinge point of the hinge rod 33 on the condensing device 2 is not restricted, and is preferably a point far from the rotation center. In the embodiment using the rotating column 5, the hinge point is any point on the vertical line on the side of the long side of the condensing device 2 that is farthest horizontally from the vertical line where the rotating column 5 is located. In the embodiment where a support portion 11 is also provided on the basis of the rotating column 5, the hinge point is preferably a point on the vertical line farthest from the bottom end of the condensing device 2 to reduce the force component that needs to overcome the friction between the condensing device 2 and the support portion 11 in the thrust, that is, when the lower portion of the condensing device 2 includes a lapped portion lapped on the support portion 11, the upper portion of the condensing device 2 corresponding to the lower portion includes a pushing portion for connecting with the hinge rod 33.

[0048] The structure of the condensing device 2 is not limited. In some embodiments, Figure 1 As shown, the condensing device 2 includes a water distribution spraying part 21 for spraying cooling water, a filler 22 for dispersing cooling water, and a heat exchanger 23 for receiving cooling water in order from top to bottom. When in use, the refrigerant enters the heat exchanger 23 through a flexible connecting pipe; the cooling water sprayed by the water distribution spraying part 21 is first sprayed on the filler 22, dispersed on the filler 22 and forms a water film, so that the cooling water itself is cooled; the cooled cooling water then falls on the heat exchange surface of the heat exchanger 23 to form a water film for heat exchange. The water on the heat exchanger 23 will fall into the bottom of the air flow channel 1, so a water collection tank for collecting cooling water is also provided at the inner bottom of the air flow channel 1. The water distribution spraying part 21, the filler 22, and the heat exchanger 23 are integrated together through an outer frame, so that the condensing device 2 appears as a vertical whole. In some embodiments, a water pump can also be provided to pump the water in the water collection tank back into the water distribution spraying part 21 for recycling. In addition, the structure of the filler 22 is not limited. In some embodiments, the filler 22 is a honeycomb filler. The structure of the heat exchanger 23 is not limited. In some embodiments, the heat exchanger 23 is a plate heat exchanger.

[0049] In some embodiments, the condenser also includes a wind power device 4 for driving the airflow through the airflow channel 1. When the condensing device 2 is working, the wind power device 4 forces the airflow to pass through the airflow channel 1, and also forces the airflow to pass through the condensing device 2 itself, thereby accelerating the heat dissipation of the cooling water on the filler 22 and also accelerating the heat exchange of the heat exchanger 23.

[0050] When the condensing device 2 is maintained to dissipate heat, after the condensing device 2 is pushed open, the wind device 4 forces the airflow to pass through the airflow channel 1 to accelerate ventilation and heat dissipation between the condensing device 2 and the airflow channel 1 .

[0051] When the condensing device 2 is used in a season when freezing is imminent, the condensing device 2 is rotated so that the air inlet surface of the condensing device 2 is no longer parallel to the air inlet of the airflow channel 1, which can reduce the airflow passing through the condensing device 2 itself and reduce the heat exchange of the airflow to the cooling water, thereby increasing the water temperature in the condensing device 2 and preventing the freezing of the water in the condensing device 2 and affecting the heat exchange function. In the embodiment with the water distribution spraying member 21 and the wind device 4, the high-speed airflow generated by the wind device 4 easily leads the cooling water or the water mist generated by the heat exchange to flow out of the airflow channel 1, so it is preferred to set a water baffle on the air outlet surface of the condensing device 2 to prevent the water mist from drifting out.

[0052] The number of condensing devices 2 is not limited and can be one or more. In some embodiments, one condensing device 2 is provided, the rotation center axis of the condensing device 2 is arranged at the center of the airflow channel 1, and the guide portion 31 of the driving device 3 is arranged at a position near the side edge at the top of the airflow channel 1 to apply force to the side edge of the condensing device 2.

[0053] In other embodiments, Figure 1 and Figure 2 As shown, two condensing devices 2 are provided. The two condensing devices 2 are respectively hinged with guide blocks 32 through hinge rods 33, and the two guide blocks 32 are symmetrically arranged on a guide portion 31, and the two guide blocks 32 are connected to the same power structure 34. At this time, the guide portion 31 is arranged at the center of the top of the airflow channel 1, and the two condensing devices 2 are also symmetrically arranged with the vertical plane where the guide portion 31 is located as the center.

[0054] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
