Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to an evaporative condenser heat exchange device. Background Art

[0002] With the rapid development of refrigeration, air conditioning, energy and other fields, the market demand for condensing heat exchangers continues to grow. In the future, the research and development focus of condensing heat exchangers will be on improving efficiency, reducing energy consumption, and extending service life. At the same time, condensing heat exchangers will also be closely integrated with new energy, energy conservation and environmental protection and other fields to develop more environmentally friendly and efficient new products.

[0003] Different groups of people have different demands for condensers, so the research and development of condensers have different focuses. For example, a Chinese patent (publication number: CN217636285U) discloses an improved structure of a large-square condenser heat exchange structure, including a core bottom plate, which is a condenser connection device on both sides; a condenser, the condenser is V-shaped and fixedly installed on both sides of the core bottom plate; a sealing cover, the sealing cover is arranged on the top of the condenser and is clamped and fixed with the condenser. The utility model improves the condenser placement structure to make the condenser V-shaped, which can effectively reduce its space and can also be reduced to the effective distance between the core and the motor to increase the heat exchange effect. The structure of the sealing cover ensures that the internal sealing environment of the condenser is based on the structure, which makes it convenient to disassemble and assemble the condenser and facilitates the replacement and maintenance of the internal facilities of the condenser. The elastic telescopic structure and the rotating structure of the hook will not hinder the installation of the sealing cover, while ensuring the connection stability and sealing of the sealing cover.

[0004] In this patent, the condenser is distributed in a V shape and is fixedly installed on the upper sides of the core bottom plate. A sealing gasket is fixedly connected to the outer bottom of the condenser. Slide rails are arranged on the upper sides of the sealing gasket. The slide rails are fixedly connected to the inner walls of the outer ends of the condenser, and the heat in the tube is transferred to the air near the tube in a very fast manner. However, there are still certain problems. The heat exchange efficiency is not high, and the heat exchange method still uses air circulation to take away the heat, which will prolong the heat exchange time of the condenser, resulting in the machine to be cooled cannot be cooled quickly. Multiple condensers are required to work at the same time, which not only increases the cost but also has the risk of machine burnout and even endangers the staff. Therefore, an evaporative condenser heat exchange device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0023] See also Figure 1-2 and Figure 5In this embodiment, an evaporative condenser heat exchange device includes a box body 1, a serpentine condenser tube 2 is fixed to the inner cavity of the box body 1, a fan 3 is fixed to the top of the box body 1, a plurality of heat dissipation holes 4 are opened at the bottom of the box body 1, an evaporation mechanism 5 that can reciprocate up and down and spray water mist is provided in the box body 1, a fixing plate 10 is fixed to the right side of the box body 1, a water pump 8 is fixed to the left side of the box body 1, a water inlet pipe 9 and a bellows 7 are fixed to the water inlet end and the water outlet end of the water pump 8 respectively, and a water outlet pipe 6 that runs through the outside of the box body 1 is connected to the left side of the evaporation mechanism 5, and the bottom of the water outlet pipe 6 is fixed to the bellows 7.

[0024] In addition, both ends of the four condensers 2 pass through the box body 1 and extend to its outside. Both ends of the condensers 2 are threaded with covers. Multiple heat dissipation holes 4 are evenly arranged and are octagonal as a whole. The covers can be covered when not in use to prevent dust in the air from contaminating the condensers 2, which facilitates installation.

[0025] It needs to be further explained that a joint is fixed on the top of the bellows 7, and the top of the joint is fixed to the water outlet pipe 6. The water outlet pipe 6 passes through the vertical through hole in the middle of the left side to the inside of the casing 1. When the water outlet pipe 6 moves with the evaporation mechanism 5, the bellows 7 will be pulled. By fixing the bellows 7 and the water outlet pipe 6, the pulling of the water outlet pipe 6 on the parts below can be offset to avoid damage to the parts during movement.

[0026] In this embodiment, after starting the fan 3, the water pump 8 and the evaporation mechanism 5 are turned on at the same time. The evaporation mechanism 5 moves up and down and sprays water mist. The water mist is evaporated under the action of the fan 3, so that the water mist takes away a large amount of heat on the condenser 2, which can improve the heat exchange efficiency. At the same time, the vertical through holes opened on the left and right sides of the box body 1 can further improve the heat exchange efficiency.

[0027] See also Figure 3-4In order to further improve the heat exchange efficiency, the evaporation mechanism 5 in this embodiment includes a servo motor 501 fixed to the right end of the box body 1, and the output shaft of the servo motor 501 is fixed with a rotating rod 502. The end of the rotating rod 502 away from the servo motor 501 is movably connected with a connecting rod 503. The connecting rod 503 is a long hollow rod. The water outlet pipe 6 is connected to the flat tube 507. The right side of the connecting rod 503 is hinged with a fixed rod 504, and the left side of the connecting rod 503 is movably connected with a connecting rod 505. The outer surface of the connecting rod 505 is hinged with a There are three water spray pipes 506 in the inner cavity of the body 1, and the left side of the water spray pipe 506 is connected to a flat tube 507. The connecting rod 503 swings up and down around the fixed rod 504 under the action of the servo motor 501. The connecting rod 505, which should originally swing up and down with the connecting rod 503, can split the movement into two directions of up and down movement and left and right movement. Since the connecting rod 503 is a long hollow rod, the connecting rod 505 can slide left and right inside the connecting rod 503, so the left and right movement of the connecting rod 505 can be offset, causing it to move up and down.

[0028] It can be known that the left and right side walls of the box body 1 are provided with three vertical through holes for the flat tube 507 and the connecting rod 505 to move respectively, and the vertical through holes are connected to horizontal through holes opened on the box body 1 and for the flat tube 507 and the connecting rod 505 to move respectively. The back side of the fixed plate 10 is fixed to the fixed rod 504, and the connecting rod 503 passes through the vertical through hole in the middle of the right side. The vertical through holes can facilitate the movable connection between the connecting rod 505 and the connecting rod 503, and the horizontal through holes can limit the flat tube 507 and the connecting rod 505 to avoid left and right movement, thereby ensuring smooth up and down reciprocating movement.

[0029] In addition, the water outlet pipe 6 is connected to the flat tube 507, and one end of the water outlet pipe 6 connected to the flat tube 507 is tapered. The outer surfaces of the three water spray pipes 506 are provided with multiple equidistantly arranged water mist outlet holes, and the multiple water mist outlet holes are connected to mist nozzles. The right sides of the three water spray pipes 506 are fixed with hinged joints, and the three hinged joints are hinged to the connecting rod 505. The setting of a cone can further increase the water pressure and make it easier to form water mist. The setting of multiple equidistantly arranged mist nozzles can increase the coverage of the water mist and avoid spray leakage.

[0030] It should be noted that, under the action of the servo motor 501 and the water pump 8, the water spray pipe 506 is prompted to spray water while moving, thereby increasing the water spray coverage area and improving the evaporation efficiency, providing a continuous supply of water mist for evaporation, promoting uninterrupted evaporation, and further improving the heat exchange efficiency.

[0031] It can be understood that after starting the fan 3, the water pump 8 and the servo motor 501 are started at the same time, prompting the water spray pipe 506 to move up and down to spray water to promote the water spraying effect. The water spray pipe 506 continues to move up and down to spray water, so that water mist can continue to be attached to the condenser 2 to ensure continuous evaporation. At the same time, with the cooperation of the fan 3, the evaporation efficiency is further improved, and the water mist attached to the condenser 2 is prompted to evaporate, taking away a large amount of heat, and finally discharged through the heat dissipation hole 4 to achieve efficient heat exchange.

[0032] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0033] The working principle of the above embodiment is:

[0034] Start the fan 3, and start the water pump 8 and the servo motor 501 at the same time. The water pump 8 will let the water flow from the water inlet pipe 9 through the bellows 7 and the water outlet pipe 6 into the flat tube 507. Since the flat tube 507 is connected to the three water spray pipes 506, the water flows through the flat tube 507 into the water spray pipe 506 and finally sprays out water mist through the atomizing nozzle. At the same time, the output shaft of the servo motor 501 rotates to drive the rotating rod 502 fixed thereon to rotate synchronously. Since the connecting rod 503 is connected to the rotating rod 502 and the fixed rod 504 at the same time, the connecting rod 503 swings up and down, driving the connecting rod 505, the water spray pipe 506, the flat tube 507 and the water outlet pipe 6 to move up and down together, so that the water mist is evenly distributed. Attached to the condenser 2, the bellows 7 has a telescopic property, so that when the water outlet pipe 6 moves up and down, the bellows 7 can follow its up and down telescopic movement, and then the fan 3 blows external air into the box body 1 to cause the water mist attached to the condenser 2 to evaporate and take away a large amount of heat. Under the action of the fan 3, the water vapor is discharged from the box body 1 through the heat dissipation holes 4 together with the air, and the above process is repeated continuously to complete the heat exchange. The fan 3, the evaporation mechanism 5 and the water pump 8 cooperate to spray water mist from the atomizing nozzle, and then the fan 3 causes the water mist to evaporate and take away the heat to realize the heat exchange process. This evaporative condenser heat exchange device can quickly take away the heat on the condenser 2, thereby greatly improving the heat exchange efficiency.
