Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0035] like Figures 1 to 3 As shown, this utility model provides a radiator blowing structure that uses compressed air to clean the surface of the radiator, including:
[0036] Gas pipeline 1, which is connected to compressed air;
[0037] The purge frame 2 includes a hollow pipe 21 connected to the air supply pipe 1. The hollow pipe 21 has a plurality of air holes 211 arranged toward the radiator. The compressed air flows into the purge frame 2 through the air supply pipe 1 and forms a high-speed airflow toward the radiator through the air holes 211.
[0038] To better illustrate the radiator blowing structure of this utility model, the following specific application will be used as an example: During operation, the compressed air flows into the blowing frame 2 through the air supply pipe 1, forming a high-speed airflow towards the radiator via the air holes 211. During this process, the pressure energy in the compressed air is generated when the compressed air passes through the air holes 211. Due to the small cross-sectional area of the nozzle, according to the principle of fluid continuity and Bernoulli's equation, the compressed air forms a high-speed airflow at the nozzle, gaining significant kinetic energy. This high-speed airflow directly acts on the radiator surface. When the airflow impacts dust particles, it exerts an impact force on the dust particles. This impact force overcomes the adhesion and friction between the dust and the object's surface, causing the dust particles to be ejected from the object's surface. First, during compressed air purging, in addition to the direct impact force, the airflow also generates shear force on the object's surface. When the high-speed airflow flows along the object's surface, a velocity difference exists between the airflow and the surface, generating shear stress. This shear force subjects dust particles to a force along the tangential direction of the object's surface. This force causes the dust particles to slide or roll on the surface, further breaking down the bond between the dust and the surface, making it easier for the dust to peel off. This is especially true for larger, more firmly adhered dust layers, where the shear force can gradually peel the dust layer into smaller pieces, which can then be blown away by the impact force. Finally, during compressed air purging, the high-speed airflow creates an air curtain near the object's surface. This air curtain prevents dust from the surrounding environment from re-adhering to the purged surface, providing a certain degree of isolation and protection.
[0039] In some possible embodiments of this utility model, the radiator blowing structure further includes a plurality of nozzles adapted to the air holes 211. The nozzles are set at the corresponding air holes 211. When the compressed air flows into the blowing frame 2 through the air supply pipe 1, it is ejected from the nozzle through the air holes 211, thereby forming a high-speed airflow blowing towards the radiator. Different types of nozzles are used to control different blowing effects.
[0040] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the purge frame 2 includes multiple hollow pipes 21, which are interconnected to form a closed or semi-closed structure. Multiple hollow pipes 21 form a purge frame 2 that is compatible with the heat exchanger, making it more versatile. The semi-closed structure has lower manufacturing costs and is more convenient to produce, while the closed structure ensures that compressed air flows more smoothly in the purge frame 2.
[0041] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2As shown, the hollow pipe 21 can be in various shapes, including but not limited to square pipe, round pipe, teardrop pipe, patterned pipe, and special-shaped pipe, or one or more of these. The various shapes of hollow pipe 21 correspond to different frame structures, and the different frame structures are adapted to different radiator layouts and sizes, thereby meeting the heat dissipation requirements of different radiators.
[0042] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the hollow pipe 21 consists of two semi-circular pipes and three straight pipes. The two ends of the two straight pipes are connected to the two ends of the two semi-circular pipes, forming a "racetrack" structure. The two ends of the other straight pipe are connected to the middle of the two semi-circular pipes. The resulting purging frame 2 is a symmetrical closed structure. The air supply pipe 1 is connected to the middle of one of the straight pipes. When compressed air is input into the hollow pipe 21 through the air supply pipe 1, the air pressure at any point in the hollow pipe 21 is the same, which facilitates the control of the purging effect.
[0043] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the sum of the areas S1 of the outlet cross sections of all the vents 211 is related to the inlet cross section S2 of the air supply pipe 1 as follows: S1 < 5S2. This ensures that a high-speed airflow is formed through the vents 211 and blown toward the radiator, meeting the minimum requirements for dust removal. Furthermore, the relationship between the sum of the areas S1 of the outlet cross sections of all the vents 211 and the inlet cross section S2 of the air supply pipe 1 can be further limited to: S2 ≤ S1 ≤ 2S2. This ensures that a high-speed airflow is formed through the vents 211 and blown toward the radiator, resulting in a better dust removal effect.
[0044] In some possible embodiments of this utility model, the shape of the pore 211 includes, but is not limited to, one or more of the following: circular, spherical, elliptical, cyclone-shaped, and caterpillar-shaped. The various pore 211 shapes correspond to different purging strategies.
[0045] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the air hole 211 is circular, with a diameter ranging from 1mm to 15mm. Within this range, a suitable purging effect can be ensured.
[0046] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 Figure 1 Figure 2As shown, the air holes 211 are staggered on the hollow pipe 21, and the included angle between the lines connecting adjacent air holes 211 is in the range of 15° to 180°. The staggered distribution of the gas corresponds to different outer contours of the radiator and different dust removal requirements. The blowing effect is optimized by continuously adjusting the distribution of the air holes 211.
[0047] To address the aforementioned problems, this utility model also provides a radiator blowing system, comprising:
[0048] A power pack containing compressed air;
[0049] In the above-mentioned radiator blowing structure, the power pack is connected to the blowing frame 2 through the air supply pipe 1.
[0050] To better illustrate the radiator purging system of this invention, the following specific application will be used as an example: During operation, the radiator purging system of this invention utilizes a power pack containing compressed gas to replace the air compressor, reducing the overall system size and making it possible to install in space-constrained equipment such as heavy trucks. Simultaneously, the power pack and the purging frame 2 are connected via an air supply pipe 1. This separate design allows the power pack and the purging frame 2 to be installed independently, further improving space utilization. It can be seen that the radiator purging structure and system of this invention utilize compressed air to form a high-speed airflow through the air holes 211 to purge the radiator surface, solving the problems of low cleaning efficiency, cumbersome processes, and limited applicability of existing heavy truck radiator cleaning technologies.
[0051] In some possible embodiments of this utility model, the radiator purging system further includes a control unit electrically connected to the power pack. The control unit controls the opening and closing, interval, and duration of compressed air release. By controlling the interval of compressed air release, the frequency of a single purging cycle can be adjusted, thereby achieving a suitable frequency based on the current working environment, ensuring purging effectiveness while reducing losses. Adjusting the duration of a single compressed air release adjusts the purging effect, ensuring the dust removal efficiency of each purging cycle. It should also be noted that in this embodiment, using this pulse effect for intermittent purging greatly reduces compressed air consumption, while the interval time ensures that the power pack compresses the compressed air to the target pressure before releasing it.
[0052] In summary, the radiator blowing structure and system of this utility model have the following advantages:
[0053] 1. Highly efficient dust removal effect:
[0054] Compressed air is used to form a high-speed airflow through the air hole 211, which directly impacts the dust particles, overcomes the adhesion and friction between the dust and the radiator surface, and causes the dust particles to detach from the radiator surface.
[0055] The airflow creates shear force on the radiator surface, further breaking the bond between dust and the radiator surface, which is especially suitable for dust layers with strong adhesion.
[0056] The air curtain formed by the high-speed airflow can prevent dust from re-adhering and protect the surface of the radiator.
[0057] 2. Flexible structural design:
[0058] The blow-through frame 2 can be adjusted according to the layout and size of the radiator, including various shapes of hollow pipes 21 such as square pipes, round pipes, teardrop pipes, etc., and different combination methods such as "racetrack" structure, to meet the needs of different radiators.
[0059] The shape and distribution of the vents 211 can be optimized according to the outer contour of the radiator and the dust removal requirements. For example, the vents 211 can be staggered to further improve the blowing effect.
[0060] 3. Optimized airflow control:
[0061] By rationally designing the relationship between the outlet cross-sectional area of the vent 211 and the inlet cross-sectional area of the gas pipeline 1, such as S1 < 5S2 or S2 ≤ S1 ≤ 2S2, the formation of high-speed airflow is ensured to meet the purging requirements.
[0062] 4. The diameter range of the pores 211 is 1mm to 15mm and the distribution angle is 15° to 180°, which can be adjusted according to different needs to further optimize the purging effect.
[0063] 5. System integration and space optimization:
[0064] The radiator purging system uses a power pack to store compressed air, replacing the traditional air compressor, which reduces the system size and makes it suitable for installation in space-constrained equipment such as heavy trucks.
[0065] The power pack and the purging frame 2 are connected by the air supply pipe 1, and the split design improves space utilization.
[0066] 6. Intelligent control:
[0067] The system is equipped with a control unit that can adjust the opening, closing, interval, and duration of compressed air release to achieve a pulse purging effect, which can both ensure the purging effect and reduce the consumption of compressed air.
[0068] This utility model's radiator cleaning structure and system utilizes compressed air to create a high-speed airflow, achieving efficient and flexible radiator cleaning. Its design not only effectively removes dust but can also be customized to suit different radiator layouts and needs. Furthermore, the system employs a power pack and a split design, optimizing space utilization, and achieves efficient cleaning and resource conservation through an intelligent control unit. This patent solves the problems of low radiator cleaning efficiency, cumbersome processes, and limited applicability in existing technologies, demonstrating significant innovation and practicality. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.
[0069] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
