Description

Technical Field

[0001] This utility model belongs to the field of radiator core technology, specifically relating to a radiator core with corrugated longitudinal heat dissipation strips. Background Technology

[0002] The corrugated longitudinal heat dissipation strip radiator core is a highly efficient heat dissipation structure. Through its corrugated design and longitudinally arranged heat dissipation strips, it improves heat dissipation efficiency and fluid flow performance. The corrugated shape of the strips increases the heat dissipation area, while the corrugated structure disrupts the fluid boundary layer, promoting turbulence and enhancing heat transfer efficiency. The longitudinal arrangement of the strips allows for smoother fluid flow, reducing flow resistance and improving fluid uniformity and heat transfer efficiency. The heat dissipation strips and heat pipes (or substrate) are connected by welding or brazing to form a stable core structure. The alternating arrangement of corrugated heat dissipation strips and heat pipes creates highly efficient heat exchange channels. The corrugated longitudinal heat dissipation strip radiator core has significant advantages in high-efficiency heat dissipation, low flow resistance, and structural stability, making it suitable for high-heat-dissipation applications such as automobiles and industrial equipment. In the future, through material innovation (such as aluminum alloys and copper alloys) and process optimization (such as vacuum brazing), its performance and reliability can be further improved.

[0003] Currently, in the use of existing corrugated longitudinal heat dissipation strips, although the corrugated heat dissipation strips can disturb the airflow, in some harsh working environments, such as areas with a lot of dust and sandstorms, impurities in the air can easily accumulate in the corrugated gaps and louver holes of the heat dissipation strips, thereby causing blockage of the heat dissipation channels and affecting the heat dissipation effect. Utility Model Content

[0004] The purpose of this invention is to provide a radiator core with a corrugated longitudinal heat dissipation strip, which aims to solve the problem that, in the use of existing radiator cores with corrugated longitudinal heat dissipation strips, although the corrugated heat dissipation strip can disturb the airflow, in some harsh working environments, such as areas with a lot of dust and sandstorms, impurities in the air are easily accumulated in the corrugated gaps and louver holes of the heat dissipation strip, thereby causing blockage of the heat dissipation channel and affecting the heat dissipation effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a radiator core with a corrugated longitudinal heat dissipation strip, comprising corrugated heat dissipation fins, wherein a heat-conducting plate is fixedly connected to the top and bottom of the corrugated heat dissipation fins, four radiator through-tubes penetrate the outer wall of the corrugated heat dissipation fins, and a mounting base is fixedly connected to the outer wall of the heat-conducting plate.

[0006] A return spring is movably connected inside the mounting base. A movable block is fixedly connected to the end of the return spring. A limit pin is fixedly connected to one end of the movable block. A lever is fixedly connected to the outer wall of the movable block. Two mounting brackets are symmetrically distributed on the outer wall of the corrugated heat dissipation fins. Filter screens are installed on the surface of the two mounting brackets. A positioning groove is opened at the end of the mounting bracket. Two fixing blocks are fixedly connected to the inner side of the positioning groove. Limit slots are opened on the outer wall of the two fixing blocks.

[0007] As a preferred embodiment of the radiator core of the corrugated longitudinal heat dissipation strip of this utility model, the mounting bracket can form an elastic engagement structure with the heat-conducting plate through a mounting base, a return spring, a movable block, a limiting pin, a toggle block, a positioning groove, a fixing block, and a limiting groove.

[0008] As a preferred embodiment of the radiator core of the corrugated longitudinal heat dissipation strip of this utility model, the size of the limiting slot is adapted to one end of the limiting pin.

[0009] In a preferred embodiment of the radiator core of the corrugated longitudinal heat dissipation strip of this utility model, the mounting base is located inside the positioning groove.

[0010] As a preferred embodiment of the radiator core of the corrugated longitudinal heat dissipation strip of this utility model, the ends of the mounting base are respectively attached to a fixing block.

[0011] As a preferred embodiment of the radiator core of the corrugated longitudinal heat dissipation strip of this utility model, the outer wall of the mounting base has an opening, and the lever extends to the outside through the opening of the outer wall of the mounting base.

[0012] As a preferred embodiment of the radiator core of the corrugated longitudinal heat dissipation strip of this utility model, the two fixing blocks are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By moving the toggle lever, the movable block retracts the limiting pin, allowing the two mounting brackets to be fitted onto the corrugated heat sink fins from the side. The mounting base then embeds into the positioning groove, with its end fitting against the fixed block. Releasing the toggle lever allows the limiting pin to spring out and insert into the limiting slot under the action of the return spring, thus installing the filter screen on the outer wall of the corrugated heat sink fins. The filter screen prevents sand and debris from entering the gaps in the corrugated heat sink fins. Conversely, moving the toggle lever retracts the limiting pin, allowing one end of the limiting pin to disengage from the limiting slot on the outer wall of the fixed block. Pulling the mounting bracket outwards disengages the mounting base from the positioning groove, making it easy to remove and clean the filter screen. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a heat sink core with a corrugated longitudinal heat dissipation strip, including a corrugated heat dissipation fin 1, a heat conduction plate 2 fixedly connected to the top and bottom of the corrugated heat dissipation fin 1, four heat sink pipes 3 penetrating through the outer wall of the corrugated heat dissipation fin 1, and a mounting base 4 fixedly connected to the outer wall of the heat conduction plate 2.

[0023] A return spring 5 is movably connected inside the mounting base 4. A movable block 6 is fixedly connected to the end of the return spring 5. A limit pin 7 is fixedly connected to one end of the movable block 6. A lever 8 is fixedly connected to the outer wall of the movable block 6. Two mounting brackets 9 are symmetrically distributed on the outer wall of the corrugated heat dissipation fins 1. A filter screen 10 is installed on the surface of the two mounting brackets 9. A positioning groove 11 is opened at the end of the mounting bracket 9. Two fixing blocks 12 are fixedly connected to the inner side of the positioning groove 11. A limit pin 13 is opened on the outer wall of the two fixing blocks 12.

[0024] It is important to note that the corrugated shape of the heat sink fins 1 increases the surface area, allowing heat to come into more complete contact with the air, accelerating heat dissipation. It effectively disturbs the flowing air, breaks down the air adhesion layer, and enhances the heat exchange efficiency between the air and the fins. The corrugated structure provides a certain degree of rigidity and stability, enabling it to withstand certain external forces and vibrations. The material is typically aluminum alloy. Aluminum alloy has low density and light weight, reducing the overall weight of the heat sink. It also has good thermal conductivity, quickly transferring heat from the cooling pipes to the fin surface, and good corrosion resistance, making it suitable for various working environments.

[0025] Among them, the heat conduction plate 2 can quickly conduct heat from the cooling pipe to the heat dissipation fins, reduce heat loss during the conduction process, ensure close contact with the cooling pipe and heat dissipation fins, reduce contact thermal resistance, and improve heat conduction efficiency. While meeting the heat conduction performance, it also has a certain degree of flexibility to adapt to the slight deformation of the heat sink under different working conditions. The material is generally copper or aluminum alloy.

[0026] Finally, the radiator tube 3 has a certain pressure resistance to withstand the pressure in the cooling system, preventing it from breaking due to excessive pressure. It can also resist the corrosion of coolant and the influence of external environmental factors, extending its service life. The material is mostly metal tubes made of copper or aluminum alloy, and there are also cases where engineering plastics are used.

[0027] Preferably, the mounting bracket 9 can form an elastic engagement structure with the heat-conducting plate 2 through the mounting base 4, the return spring 5, the movable block 6, the limit pin 7, the push block 8, the positioning groove 11, the fixing block 12, and the limit groove 13.

[0028] In practical use, by moving the toggle block 8 to move the movable block 6, the limiting pin 7 is retracted. Then, the two mounting brackets 9 are fitted onto the corrugated heat dissipation fins 1 from the side, so that the mounting base 4 can be embedded in the positioning groove 11. At this time, the end of the mounting base 4 will be in contact with the fixing block 12. Then, by releasing the toggle block 8, the limiting pin 7 can be popped out and inserted into the limiting slot 13 under the action of the return spring 5, so that the filter screen 10 is installed on the outer wall of the corrugated heat dissipation fins 1. The filter screen 10 can prevent sand and dust from entering the gaps of the corrugated heat dissipation fins 1.

[0029] Preferably, the size of the limiting slot 13 is adapted to the size of one end of the limiting pin 7, the mounting base 4 is located inside the positioning slot 11, the ends of the mounting base 4 are respectively attached to a fixing block 12, the outer wall of the mounting base 4 has an opening, and the push block 8 extends to the outside through the opening of the outer wall of the mounting base 4, and the two fixing blocks 12 are symmetrically distributed.

[0030] In practical use, by moving the toggle block 8 to move the movable block 6, the limit pin 7 is retracted, so that one end of the limit pin 7 can be disengaged from the limit slot 13 on the outer wall of the fixed block 12. Then, by pulling the mounting bracket 9 outward, the mounting seat 4 is disengaged from the positioning slot 11, so that the filter screen 10 can be easily removed and cleaned.

[0031] Working principle: First, by moving the toggle block 8 to move the movable block 6, the limiting pin 7 is retracted. Then, the two mounting brackets 9 are fitted onto the corrugated heat dissipation fins 1 from the side, allowing the mounting base 4 to be embedded in the positioning groove 11. At this time, the end of the mounting base 4 will be in contact with the fixing block 12. Then, by releasing the toggle block 8, the limiting pin 7 can be ejected under the action of the return spring 5 and inserted into the limiting groove 13, thereby installing the filter screen 10 on the outer wall of the corrugated heat dissipation fins 1. The filter screen 10 can prevent sand and dust from entering the gaps of the corrugated heat dissipation fins 1. Conversely, by moving the toggle block 8 to move the movable block 6, the limiting pin 7 is retracted, allowing one end of the limiting pin 7 to disengage from the limiting groove 13 on the outer wall of the fixing block 12. Then, by pulling the mounting bracket 9 outward, the mounting base 4 is disengaged from the positioning groove 11, thus making it easy to remove the filter screen 10 for cleaning.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
