In order to solve the problems that it is difficult to conduct continuous heat dissipation during the use of the current radiator, which is likely to affect the working efficiency of the internal combustion engine, it is not easy to protect the internal combustion engine and filter, impurities are easily driven to the surface of the radiator during the heat dissipation process, and the service life of the radiator is easily shortened. Through a low-temperature liquid pump cooperating with a water storage tank and a fan body, low-temperature gas is generated for continuous air-cooling, and during the use process, a filter plate is used to filter dust to prevent the dust from adhering to the radiator and affecting heat dissipation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings, but the embodiments of the present utility model are not limited thereto.

[0024] As Figures 1-4 shown, this embodiment provides a radiator for an internal combustion engine, including a fixed frame 1, water delivery pipes 2 installed at the upper and lower ends of the fixed frame 1, and diversion pipes 3 uniformly installed between the two groups of water delivery pipes 2. The two sides of the fixed frame 1 are installed with a rectangular frame 4 by a clamping method. Heat dissipation fins 5 are uniformly installed between the two sides inside the rectangular frame 4. The heat dissipation fins 5 are perpendicular to the diversion pipes 3. Arc grooves 6 are opened on the side edges of the heat dissipation fins 5 close to the diversion pipes 3. The inner diameter of the arc grooves 6 is the same as the outer diameter of the diversion pipes 3, and the arc grooves 6 are attached to the outer side edges of the diversion pipes 3.

[0025] General working principle: During heat dissipation, the prior art in the comparative document is adopted. A low-temperature liquid pump is used to pump the water inside the water storage tank into the inner part of the top water delivery pipe 2. Then, the low-temperature liquid enters the inner part of the diversion pipe 3 and flows downward into the inner part of another water delivery pipe 2. The bottom water delivery pipe 2 is then connected to the water storage tank to circulate the low-temperature liquid. At the same time, the fan is started to blow air towards the fixed frame 1. The low-temperature liquid cools the heat-conducting fins 5 and the diversion pipe 3 through the way of contact transfer. After the gas passes through the gaps between the heat-conducting fins 5 and the diversion pipe 3, the contact area with the refrigerant is increased, and the cooling rate is accelerated. Then, the cold air is blown towards the internal combustion engine for heat dissipation.

[0026] In this embodiment, slots 12 are opened at the top and bottom on both sides of the fixed frame 1. Plug blocks 11 that cooperate with the slots 12 are fixedly arranged on the outer sides of the rectangular frames 4. The plug blocks 11 are inserted into the inner parts of the slots 12. A positioning hole 13 penetrating through to the inner part of the slot 12 is opened at the top of the fixed frame 1.

[0027] Local working principle: During the assembly process of the device, the plug blocks 11 on the rectangular frames 4 are aligned with the slots 12, then the plug blocks 11 are inserted into the inner parts of the slots 12, and finally the bolts pass through the positioning holes 13 and are tightened on the tops of the plug blocks 11.

[0028] In this embodiment, guide grooves 7 are opened at the top and bottom on the outer sides of the rectangular frames 4. The guide grooves 7 are parallel to the heat-conducting fins 5. A U-shaped plate 8 is slidably arranged between the two groups of guide grooves 7. Scrapers 9 are evenly fixedly arranged on the inner sides of the U-shaped plate 8. The scrapers 9 are located between the two groups of heat-conducting fins 5, and the outer sides of the scrapers 9 are attached to the heat-conducting fins 5. One end of the scraper 9 close to the diversion pipe 3 is provided with a rubber plate. One end of the rubber plate away from the scraper 9 is aligned with the end of the heat-conducting fin 5, and the length of the rubber plate is the same as the radius of the diversion pipe 3.

[0029] Local working principle: After long-term use, some fine dust will adhere to the surfaces of the heat-conducting fins 5 and the outer sides of the diversion pipe 3. To ensure the heat-conducting effect, the U-shaped plate 8 can be directly dragged to slide. The scrapers 9 move while being attached to the heat-conducting fins 5, scraping off the dust on the top and bottom of the heat-conducting fins 5. At the same time, the rubber plate can also slide while being attached to the outer side of the diversion pipe 3 to wipe and clean the diversion pipe 3.

[0030] In this embodiment, rubber strips are fixedly arranged on the top and bottom of the scraper 9, and the rubber strips are attached to the heat-conducting fins 5.

[0031] Local working principle: The setting of the rubber strips on the scraper 9 ensures the contact effect between the scraper 9 and the heat-conducting fins 5, and at the same time avoids damaging the heat-conducting fins 5.

[0032] In this embodiment, a sliding plate 10 is vertically and slidably installed inside the fixed frame 1. The diversion pipe 3 passes through the inside of the sliding plate 10, and the sliding plate 10 is slidably connected to the diversion pipe 3.

[0033] Local working principle: When cleaning stubborn impurities on the surface of the diversion pipe 3, the rectangular frame 4 is removed, and then the sliding plate 10 is controlled to move vertically downward to clean the surface of the diversion pipe 3.

[0034] In this embodiment, smooth coatings are applied to the surfaces of the diversion pipe 3 and the heat-conducting fins 5, and both the diversion pipe 3 and the heat-conducting fins 5 are made of copper-aluminum alloy.

[0035] Local working principle: The surfaces of the diversion pipe 3 and the heat-conducting fins 5 are smooth, which reduces the adhesion effect of dust, and the copper-aluminum alloy material has a high heat-conducting effect.

[0036] In this embodiment, buckling grooves are provided on both sides of the top of the sliding plate 10, and anti-slip patterns are provided on the outer side of the U-shaped plate 8.

[0037] Local working principle: When controlling the up and down movement of the sliding plate 10, it is convenient to slide by pinching the buckling grooves with fingers. At the same time, the anti-slip patterns on the U-shaped plate 8 increase the friction with the hand, so as to stably control the movement of the U-shaped plate 8.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
