Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0024] like Figure 1-2 As shown, this embodiment provides an air conditioning unit for a well site electrical control room, including a radiator 11 and a spray cooling device. The radiator 11 is installed inside the air conditioning unit 10. The spray cooling device includes a spray generator 21 and a spray delivery pipeline 22. The spray generator 21 is used to generate fine mist particles and is installed on one side of the air conditioning unit 10. It is understood that the spray generator 21 can be fixed to one side of the air conditioning unit 10 by means of brackets, clamps, or welding. In order to improve the service life of the spray generator 21 and prevent damage from external factors, this embodiment preferably provides a fixing cover (preferably 55cm*50cm*60cm) on the outside of the air conditioning unit 10. The spray generator 21 is installed inside the fixing cover. It should be noted that the fixing cover should have an installation port for replacing and maintaining the spray generator 21. The installation port can be closed by a cover as needed. The fixing cover can be either a frame structure or a closed structure. The spray delivery pipeline 22 includes a main pipeline 221 and multiple branch pipelines 222 connected to the main pipeline 221, such as... Figure 3 As shown, the main pipe 221 is connected to the spray generator 21 to connect the spray generator 21 to multiple branch pipes 222. The number of branch pipes 222 corresponds to the number of sides of the radiator 11. Each branch pipe 222 is equipped with a nozzle 223, and the multiple branch pipes 222 extend to each air inlet side of the radiator 11 to cool the air around the air inlet.

[0025] In use, the spray generator 21 produces fine mist droplets, and the spray delivery pipeline 22 delivers these fine mist droplets to each air inlet of the radiator 11. The fine mist droplets are sprayed at the air inlets to form an effective cooling zone. The air temperature around the air inlets is reduced by rapidly absorbing heat and evaporating the fine mist droplets in the air. Specifically, the air temperature can be reduced by 8-10℃. It can be seen that this solution uses the physical principle of heat absorption by mist droplet evaporation for cooling. This method has low energy consumption and good environmental performance. It will not damage the air conditioning unit 10 and the surrounding environment, and improves the safety and service life of the air conditioning unit 10. Therefore, this solution has certain application and market promotion value for the air conditioning unit 10 in the well site electrical control room.

[0026] The spray generator 21 is preferably a PACIFICII ultrasonic pure water airflow generator manufactured by Pacific Instruments. Its spray visibility range is 2-3m, the median particle size of the mist is concentrated below 5 micrometers, the mist output is 10-65ml / min, the mist output is adjustable in three levels, it can continuously mist for 50-120 minutes, and its size is 37cm*32cm*35cm, which meets the requirements of this embodiment.

[0027] The spray delivery pipeline 22 is made of PVC material. The main pipeline 221 has a diameter of 50mm, and the branch pipeline 222 has a diameter of 25mm. The branch pipeline 222 is connected to the main pipeline 221 by a reducer that changes the diameter from 50mm to 25mm. It can be understood that each branch pipeline 222 is connected to the main pipeline 221 by a reducer, or one branch pipeline 222 is connected to the main pipeline 221 by a reducer, and the remaining branch pipelines 222 are connected to that branch pipeline 222 by a matching connector. In this embodiment, the latter is preferred. The branch pipeline 222 includes three branches, which form a concave structure that can be adapted to the length and width of the radiator 11.

[0028] In this embodiment, the branch pipe 222 can be one or more layers. When it is multiple layers, the multiple branch pipes 222 are equidistantly arranged and connected by a connecting pipe, such as... Figure 8 As shown; using a multi-layer setting can increase the cooling area and achieve the purpose of rapid cooling. Admittedly, while using spray to cool a large area, it will also increase the humidity of the surrounding air. Therefore, in this embodiment, it is preferable to set a manual valve on the connecting pipe so as to flexibly and selectively start one or more branch pipes 222 as needed. It is understood that the manual valve can be a conventional manual shut-off valve.

[0029] The branch pipe 222 can be fixed to the outer edge of the radiator 11 using detachable fasteners such as clamps or cable ties. The nozzle 223 is located at the upper and / or lower end of the branch pipe 222, that is, the spray direction of the nozzle 223 is parallel to the air inlet, ensuring that the spray forms an effective and large cooling area above the air inlet. Understandably, the specific location of the nozzle 223 is determined by the layout of the branch pipe 222 at the air inlet. When the branch pipe 222 is located near the bottom of the air inlet, it is preferable to place the nozzle 223 at the upper end of the branch pipe 222, and vice versa. When the branch pipe 222 is located in the middle of the air inlet, the nozzle is placed at the upper and lower ends of the branch pipe 222 to ensure that the cooling area formed by the fine spray covers the air inlet as much as possible, thereby improving heat dissipation efficiency.

[0030] In a preferred embodiment of this invention, a condensate guiding mechanism is provided on the branch pipe 222, such as... Figure 4-5 As shown, the condensate guiding mechanism includes fins and a water collection tank 225. The condensate fins 224 consist of multiple fins arranged side by side, and these multiple condensate fins 224 are located on the side directly opposite the air inlet. The water collection tank 225 is a groove structure, located directly below the condensate fins 224, and is used to collect condensate. The condensate fins 224 are straight plate structures or corrugated plate structures. On the one hand, the condensate fins 224 can increase the cooling area, improve airflow distribution, and increase cooling efficiency. On the other hand, as a condensate guiding plate, it can accelerate the condensation of excess fine mist particles and guide them to the water collection tank 225, preventing excess water from entering the radiator 11 and causing damage to the radiator 11. The water guided to the water collection tank 225 can evaporate naturally or be automatically discharged when a certain amount is reached.

[0031] The length of the water collection tank 225 is greater than the size of the radiator 11, that is, the water collection tank 225 extends to the outside of the air conditioning unit 10, which is conducive to the drainage of condensate. Understandably, in order to achieve automatic drainage, the height of the end of the water collection tank 225 located outside the air conditioning unit 10 is relatively low, that is, it is set at an angle, and the specific angle of inclination can be in the range of 5-10°.

[0032] The condensation fins 224 are radially inclined relative to the branch pipe 222, with an inclination angle between 15° and 30°. Figure 6-7 As shown, by tilting the device, gravity can be used to help the condensate flow downwards, preventing moisture from accumulating on the surface of the condensation fins 224.

[0033] The condensation fins 224 are fixed to each branch pipe 222 by heat fusion. The width of the condensation fins 224 corresponds to the outer diameter of the branch pipe 222, and the length corresponds to the straight-line distance between the branch pipe 222 and the air inlet. This ensures that the condensation heat sink can be used normally while avoiding interference with the heat sink 11.

[0034] The following is a set of specific experimental data obtained after using the air conditioning unit of the electrical control room in this embodiment:

[0035] On August 3, 2024, our unit installed a set of the air conditioning unit for the electrical control room described above in this embodiment in the electrical control room of the 40920 drilling team in the 21st well area; the installation and test data are shown in Table 1 below:

[0036] Table 1

[0037]

[0038] The test results show that the air conditioning unit in the electrical control room has significant heat dissipation and cooling effects. Continuous operation can reduce the external temperature of the air conditioning unit by about ten degrees. In addition, the spray cooling device uses cold water as a medium and uses a pressurized method to spray fine mist particles, which will make the cooling effect even more significant.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
