Description

Technical Field

[0001] This utility model relates to the technical field of spraying devices, specifically a spraying device with a finned heat exchange structure. Background Technology

[0002] The principle of artificial fog in space cooling is based on the dual flow of air and mist, and the principle of evaporation and heat absorption. The cooling terminal diffuses fog particles with a diameter of 1-10 micrometers into the cooling area. During the diffusion process, the particles continuously evaporate and absorb a large amount of heat energy from the area. Scientific statistics show that one kilogram of water can be activated into floating artificial fog, which is equivalent to dissolving seven kilograms of ice. Generally, it can achieve a cooling effect of 6℃-10℃, and in extreme cases, the cooling range can reach 14℃.

[0003] The existing Chinese utility model patent with publication number CN220397291U discloses a spraying device. The spraying device includes a first pipe, a spraying assembly, and a fixing assembly. The first pipe is suitable for connection to a water source. The spraying assembly includes a second pipe and a nozzle. One end of the second pipe is connected to the first pipe, and the diameter of the second pipe is smaller than that of the first pipe. The other end of the second pipe is flexibly connected to the nozzle. The nozzle can approach and move away from the carbon dioxide cylinder to spray water onto the outer surface of the carbon dioxide cylinder. The fixing assembly includes a first fixing member and a second fixing member. One end of the first fixing member is connected to the ground, and the other end of the first fixing member is connected to the second fixing member. The second fixing member cooperates with the first pipe to fix the first pipe. This utility model proposes a spraying device that can improve the spraying effect.

[0004] Existing sprinkler systems typically use water pumps to deliver water to the nozzles via pipe structures. Due to the length of the pipes, this method results in insufficient water pressure at the end of the pipes, failing to reach the required water pressure for the nozzles and affecting the sprinkler effect. Furthermore, the water sprayed by existing sprinkler systems is mostly at room temperature, resulting in poor cooling effect. Utility Model Content

[0015] Compared with the prior art, this utility model provides a spray device with a finned heat exchange structure, which has the following beneficial effects:

[0016] 1. This utility model utilizes fins, with the fins evenly spaced above the heat exchange tube, and the lower half of the fins located inside the heat exchange tube. A flow guide is fixedly installed above the heat exchange tube, covering the portion of the fins located above the heat exchange tube. A fan is fixed to the rear end inside the flow guide via a connecting plate. When the fan starts, it can extract the air inside the flow guide, and the external air will enter the flow guide from the front end under the influence of the air pressure difference, forming a backward-moving airflow. As the airflow passes through the space between the fins, it can carry away the heat from the fins, reducing the temperature of the fins. The front end of the heat exchange tube is connected to the outer shell via a flexible hose. Water enters the heat exchange tube through the water inlet pipe and passes through the space between the fins. Because the heat of the fins is carried away by the airflow, a temperature difference is created between the fins and the water flow. The heat of the water is absorbed by the fins, thereby reducing the temperature of the water. This method can cool the water, thereby improving the spray cooling effect.

[0017] 2. This utility model features a housing that is fixed to the rear side of the base. The nozzle penetrates the housing and communicates with its inner cavity.

The gear is fixedly connected to the drive shaft and is also rotatably connected to the limiting shaft via the adapter bearing. The gears mesh with each other. The top of the drive shaft penetrates the housing and is fixedly connected to the shaft of the drive motor via an insertion method. When the drive motor drives the gear to rotate via the drive shaft, the space volume on the disengaged side of the gear increases, creating a vacuum that draws in water from below. Meanwhile, the space volume on the meshing side of the gear decreases, forcing water upwards into the nozzle. This method allows for secondary pressurization of the water at the nozzle's inlet end, ensuring sufficient water pressure when the water enters the nozzle and preventing insufficient water pressure due to pipe length from affecting the spraying effect.

[0028] Specifically, the heat exchange tube 1 restricts water flow through the space between the fins 11, the fins 11 absorb heat from the water flow, the guide shroud 12 restricts airflow through the space between the fins 11, the connecting plate 13 restricts the position of the fan 15, the fixing bolt 14 facilitates the fixed connection between the connecting plate 13 and the guide shroud 12, the fan 15 exhausts air from inside the guide shroud 12, the connecting bolt 16 facilitates the connection between the fan 15 and the connecting plate 13, the water inlet pipe 17 facilitates water entering the heat exchange tube 1, the flexible hose 18 facilitates water entering the housing 19 from inside the heat exchange tube 1, the housing 19 restricts water flow through the space between the gears 117, and the base 110 restricts the position of the drive shaft 114. The limiting block 111 can clamp the support rod 112 with the base 110, thereby restricting the base 110 to the top of the support rod 112. The support rod 112 can raise the position of the base 110. The connecting bearing 113 can facilitate the rotation of the drive shaft 114. The drive shaft 114 can facilitate the drive motor 118 to drive the gear 117 to rotate.

[0029] In use, the fins 11 are equidistantly installed above the heat exchange tube 1, with the lower half of the fins 11 located inside the heat exchange tube 1. A flow guide shroud 12 is fixedly installed above the heat exchange tube 1, covering the portion of the fins 11 located above the heat exchange tube 1. The fan 15 is fixed to the rear end inside the flow guide shroud 12 via a connecting plate 13. When the fan 15 starts, it can draw out the air inside the flow guide shroud 12, and external air will enter the flow guide shroud 12 from the front end under the influence of the air pressure difference, forming... The backward-moving airflow carries away heat from the fins 11 as it passes through the space between them, lowering their temperature. The front end of the heat exchange tube 1 is connected to the outer casing 19 via a flexible hose 18. Water enters the heat exchange tube 1 through the inlet pipe 17 and flows between the fins 11. As the airflow carries away the heat from the fins 11, a temperature difference is created between the fins 11 and the water flow. The heat from the water is absorbed by the fins 11, thus lowering its temperature. This method effectively cools the water, thereby improving the efficiency of the spray cooling. As a result, the outer casing 19 is fixed to the rear side of the base 110, the nozzle 120 penetrates the outer casing 19 and communicates with the inner cavity of the outer casing 19, the outer diameter of the drive shaft 114 is the same as the outer diameter of the transition bearing 116, the drive shaft 114 is rotatably connected to the base 110 through the connecting bearing 113, the gear 117 is fixedly connected to the drive shaft 114, and the gear 117 is rotatably connected to the limiting shaft 115 through the transition bearing 116, the gears 117 mesh with each other, and the top end of the drive shaft 114 penetrates the outer casing 19 through... The gear 117 is fixedly connected to the shaft of the drive motor 118 via the drive shaft 114. When the drive motor 118 drives the gear 117 to rotate, the space volume on the disengaged side of the gear 117 increases, forming a vacuum that draws in water from below. Meanwhile, the space volume on the meshing side of the gear 117 decreases, forcing water upward into the nozzle 120. This method can pressurize the water at the water inlet of the nozzle 120 to ensure the water pressure when entering the nozzle 120, thus avoiding insufficient water pressure due to pipe length, which would affect the spraying effect.
