Description

Technical Field

[0001] The utility model relates to the technical field of surface coolers, in particular to a surface cooler with a high-efficiency drainage mechanism. Background Art

[0002] A surface cooler, also known as a surface cooler, is a device used to cool hot fluids. It usually consists of a series of cooling fins or pipes that are in contact with the fluid to be cooled, transferring heat to the surrounding environment through heat conduction and convection. Surface coolers can be used in various industrial fields, such as power plants, chemical plants, air conditioning and refrigeration systems, etc., to reduce the temperature of the fluid;

[0003] When the cooling medium contacts the surface of the condenser, it may condense into liquid due to the temperature difference. This happens when the temperature of the cooling medium is lower than the saturation temperature of the condenser surface. The condensed liquid will accumulate and flow on the surface of the condenser. Or when the humidity in the ambient air where the condenser is located is high, when the humid air contacts the surface of the condenser, the temperature difference causes water vapor to condense into liquid water.

[0004] Due to the above two main reasons or other factors, the existing surface coolers often retain a lot of liquid water and other liquids on their surfaces. If the water on the surface of the surface cooler is not removed in time, the water film or accumulation on the surface of the surface cooler will form an insulating layer, which will hinder the conduction and convection of heat, thereby reducing the heat dissipation efficiency of the surface cooler; and if the water film or accumulation on the surface of the surface cooler causes the cooling efficiency to decrease, higher energy consumption may be required to achieve the required cooling effect during system operation, which will increase energy consumption and operating costs;

[0005] Existing methods for removing water from coolers are generally gravity drainage, that is, the cooler is installed with an appropriate slope so that the liquid flows in the inclined direction to facilitate drainage; or gas blowing is used for drainage, that is, by spraying air flow onto the surface of the cooler to blow away the liquid. However, this method requires proper control of the gas flow rate and pressure to ensure that the liquid is quickly flushed away without causing damage to the cooler.

[0006] Therefore, the utility model provides a surface cooler with a high-efficiency drainage mechanism to solve the above problems. Utility Model Content

[0014] The utility model provides a surface cooler with a high-efficiency drainage mechanism. Compared with the prior art, it has the following beneficial effects:

[0015] The surface cooler with an efficient drainage mechanism can push the rotating plate to overcome the elastic force of the torsion spring and rotate through the cooperation of structures such as the rotating rod, the fan blades and the air outlet, so that the high-temperature gas between the inner cavity and the sealing shell is pushed out from the air outlet to the cooling pipe and the heat sink, so that the water on the surface of the cooling pipe and the heat sink can be quickly removed, and because the airflow carries a certain amount of heat, it can effectively prevent the surface of the surface cooler from frosting and becoming difficult to remove, thereby greatly increasing the water removal efficiency, and discharging the airflow by means of pressure relief can further ensure the efficiency and effect of water removal, and after the inner cavity and the sealing shell are exhausted once, under the action of the torsion spring, the rotating plate blocks the air outlet again to carry out the next work.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3A surface cooler with an efficient drainage mechanism comprises a shell 1 and three groups of cooling tubes 2 arranged in the shell 1. A plurality of heat sinks 3 are evenly fixed in the shell 1. The cooling tubes 2 are limited by the heat sink 3. An inner cavity 4 is arranged at the upper side wall of the shell 1. A rotary vacuum pump 6 is fixed at the side wall of the inner cavity 4. A driving gear 7 is rotated at the inner side wall of the inner cavity 4. The rotary vacuum pump 6 and the driving gear 7 are driven and connected. Both sides of the lower end of the driving gear 7 are meshed with driven gears 8. Rotating rods 9 are fixed on the side walls of the two driven gears 8. Multiple groups of fan blades 10 are fixed on the side walls of the two rotating rods 9. A plurality of air outlets 11 are evenly opened on the lower wall of the inner cavity 4. Two rotating plates 12 are rotated in the air outlet 11. The two rotating plates 12 A torsion spring 13 is provided between the air outlet 11 and the air outlet hole 11, which can push the rotating piece 12 to overcome the elastic force of the torsion spring 13 to rotate, so that the high-temperature gas between the inner cavity 4 and the sealing shell 5 is pushed out from the air outlet 11 to the cooling tube 2 and the heat sink 3, and the water on the surface of the cooling tube 2 and the heat sink 3 can be quickly removed. Since the airflow carries a certain amount of heat, it can effectively prevent the surface of the surface cooler from frosting and being difficult to remove, which greatly increases the water removal efficiency. The airflow is discharged by pressure relief, which can further ensure the efficiency and effect of water removal. After the inner cavity 4 and the sealing shell 5 are exhausted once, under the action of the torsion spring 13, the rotating piece 12 blocks the air outlet 11 again to carry out the next work.

[0022] In an optional embodiment: a sealing shell 5 is installed in the inner cavity 4 , the inner cavity 4 and the sealing shell 5 are sealed, and the rotating rod 9 and the air outlet 11 are both arranged in the sealing shell 5 .

[0023] It should be noted that the generated heat can be accumulated in the sealed shell 5. As the heat is accumulated and the inflation process proceeds between the inner cavity 4 and the sealed shell 5, when the internal pressure reaches a certain level, the rotating piece 12 can be pushed to rotate to overcome the elastic force of the torsion spring 13.

[0024] In an optional embodiment: a plurality of friction blocks 14 are evenly fixedly disposed on the lower wall of the inner cavity 4 , the friction blocks 14 are disposed on the lower wall of the rotating rod 9 , and the upper walls of the friction blocks 14 and the rotating rod 9 are in contact with each other.

[0025] It should be noted that when the rotating rod 9 and the fan blades 10 rotate, along with the operation of the rotary vacuum pump 6 , friction occurs between the friction blocks 14 during the rotation of the rotating rod 9 , which can generate a large amount of heat between the inner cavity 4 and the sealing shell 5 .

[0026] In an optional embodiment: a plurality of groups of fan blades 10 are evenly spaced apart on the side wall of the rotating rod 9, the fan blades 10 on the side walls of different rotating rods 9 are cross-arranged with each other, and the fan blades 10 and the air outlets 11 correspond to each other.

[0027] It should be noted that when the internal pressure reaches a certain level, the rotating plate 12 can be pushed to overcome the elastic force of the torsion spring 13 to rotate, thereby pushing the high-temperature gas between the inner cavity 4 and the sealing shell 5 out from the air outlet 11 to the cooling pipe 2 and the heat sink 3.

[0028] In an optional embodiment, the torsion spring 13 is made of alloy material and is a lightweight spring.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] When the device is in use, the rotary vacuum pump 6 can be turned on regularly, so that the rotary vacuum pump 6 can drive the driving gear 7 to rotate and inflate air between the inner cavity 4 and the sealed shell 5. When the driving gear 7 rotates, it drives the two driven gears 8 to rotate, and the two driven gears 8 rotate in opposite directions. When the driven gear 8 rotates, it drives the rotating rod 9 and the fan blades 10 to rotate, and the fan blades 10 on the side walls of the two rotating rods 9 rotate in opposite directions. As the rotary vacuum pump 6 works, the rotating rod 9 rotates and friction occurs between the friction block 14 at the same time, and the generated heat accumulates in the sealed shell 5. As the heat accumulates and the inflation process proceeds between the inner cavity 4 and the sealed shell 5, when the internal pressure reaches At a certain time, the rotating piece 12 can be pushed to overcome the elastic force of the torsion spring 13 and rotate, so that the high-temperature gas between the inner cavity 4 and the sealing shell 5 is pushed out from the air outlet 11 to the cooling tube 2 and the heat sink 3, and the water on the surface of the cooling tube 2 and the heat sink 3 can be quickly removed. Moreover, since the airflow carries a certain amount of heat, it can effectively prevent the surface of the surface cooler from frosting and becoming difficult to remove, thereby greatly increasing the water removal efficiency. Moreover, the airflow is discharged by means of pressure relief, which can further ensure the efficiency and effect of water removal. After the inner cavity 4 and the sealing shell 5 are exhausted once, under the action of the torsion spring 13, the rotating piece 12 blocks the air outlet 11 again to carry out the next work.
