Description

Technical Field

[0001] The present invention relates to the technical field of internal combustion engine heat dissipation, and specifically to an automatic radiator cleaning device and method. Background Art

[0002] An internal combustion engine radiator mainly consists of components such as a water chamber, a radiator inlet pipe, a radiator core, cooling pipes, radiator fins, a radiator outlet pipe, and a lower water chamber. Radiator fins are provided to increase the heat dissipation area, dissipate the heat in the cooling water pipes, and take away the heat through a fan, thereby achieving the purpose of cooling and heat dissipation. Due to the too small gaps in this radiator fin structure, dust is easily accumulated, causing the gaps to be blocked, which affects the heat dissipation effect and leads to an increase in the temperature of the internal combustion engine, resulting in equipment damage. Therefore, the radiator fins need to be cleaned regularly. Generally, they need to be disassembled and manually rinsed with a high-pressure water gun. The operation process is cumbersome and time-consuming. If the pressure of the high-pressure water gun is too high, the radiator fins are easily impacted and deformed, resulting in damage.

[0003] Publication (Announcement) No.: CN113771804A discloses an automatic cleaning system and method for an off-road vehicle radiator. It judges whether the radiator fins should be cleaned by detecting the wind pressure passing through the radiator fins with a wind pressure sensor, wets the dust and debris on the surface of the radiator fins by using a washing liquid spray head installed on the top of the radiator fins, and blows the radiator fins forward and backward repeatedly by the forward and reverse rotation of the fan to complete the cleaning of the radiator fins.

[0004] This method mainly realizes the cleaning of the radiator fins through the blowing action of the fan, and is only applicable to the case where the radiator is attached with floating dust. For the case where the sludge is tightly attached, the wetting of the washing liquid and the blowing of the fan may not be able to effectively remove it.

[0005] Publication (Announcement) No.: CN209040958U discloses an automobile engine radiator with a cleaning function. It sprays water on the surface of the radiator through arranged spray heads, and then uses a set of rotating cleaning brush rollers to clean the radiator. As the brush rollers move, the cleaning of the radiator is completed.

[0006] This prior art can only achieve the cleaning of the single-sided surface layer of the radiator fins, and it is difficult to achieve in-depth cleaning of the internal dust accumulation and effective cleaning.

[0007] Publication (Announcement) No.: CN215804801U discloses an automatic dust cleaning device for an engine radiator grille. One end face of this device is fixedly connected to the radiator. The output shaft of the internal fan drives a rotating rod to move. There is a cleaning liquid outlet on the rotating rod. The dust on the radiator is cleaned by using the cleaning liquid as a solvent, and the accumulated dust on the radiator is cleaned by the soft hair on the rotating rod.

[0008] This prior art can only clean the single-sided surface of the heat sink, and it is difficult to deeply clean the internal dust accumulation, making it difficult to achieve effective cleaning.

[0009] In summary, the technical solutions, the technical problems to be solved, and the beneficial effects of the above-disclosed technologies are all different from those of the present invention. Regarding more technical features, technical problems to be solved, and beneficial effects of the present invention, there is no technical inspiration in the above-disclosed technical documents.
