Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, specifically a high heat transfer automotive radiator heat dissipation structure. Background Technology

[0002] As a key component ensuring the stable operation of a vehicle's power system, the radiator's heat dissipation performance directly affects the reliability and service life of the entire vehicle. Currently, most automotive radiators adopt the traditional structure of flow channels and straight heat dissipation fins. The heat dissipation inside the pipes relies solely on the natural flow of coolant, lacking an effective internal heat conduction enhancement design. This results in uneven heat transfer when the coolant flows within the channels, making it easy for hot spots to form in certain areas. The heat dissipation fins outside the pipes are mostly arranged horizontally or vertically, which easily forms a stable laminar flow when the airflow passes through, resulting in a thicker thermal boundary layer and insufficient heat exchange contact. Even if some products are equipped with convex or gap structures, it is difficult to create multiple turbulence effects.

[0003] Therefore, a high heat transfer automotive radiator heat dissipation structure is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-heat-transfer automotive radiator cooling structure. Through the staggered arrangement of zigzag heat-conducting fins on the inner wall of the flow channel, the coolant flow path is divided, increasing the contact area between the coolant and the heat-conducting structure. This allows for rapid heat transfer from the coolant within the channel to the outer wall of the flow channel, extending into the heat conduction pipes inside the coolant, thus solving the problem of uneven heat conduction within the pipes in traditional structures. Simultaneously, the inclined cooling fins guide airflow to impact and flow along both sides of the fins. The raised bumps on the surface of the cooling fins initially impact the airflow, creating vortices. The elongated slots at the center of the bumps allow some airflow to pass through and form a backflow. Combined with the narrow gaps between adjacent cooling fins, this further disturbs the airflow. These three elements work together to create a multi-layered turbulence effect, thinning the thermal boundary layer as the airflow passes through the fins, allowing for more thorough contact between the airflow and the cooling fins and more complete heat exchange, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a water inlet chamber, a water outlet chamber, a heat dissipation core, and an electronic fan, wherein the water inlet chamber and the water outlet chamber are symmetrically arranged at both ends of the heat dissipation core, and the electronic fan is fixed to the air inlet side of the heat dissipation core for providing airflow to the heat dissipation core;

[0006] The heat dissipation core includes multiple parallel flow channels, a Z-shaped heat-conducting fin, and heat dissipation fins. The water inlet chamber and the water outlet chamber are both connected to the flow channels inside the heat dissipation core to form a coolant circulation loop.

[0007] Preferably, the flow channel is a tubular structure with an internal coolant flow cavity, and the Z-shaped heat-conducting fins are fixed to the inner wall of the flow channel by brazing and are evenly distributed along the length of the flow channel.

[0008] Preferably, the heat dissipation fins are fixed between the outer walls of two adjacent flow channels, the heat dissipation fins are inclined relative to the length direction of the flow channels, and the surface of the heat dissipation fins is integrally formed with a plurality of protrusions.

[0009] Preferably, a slender strip-shaped hole is provided at the center of the protrusion, and a gap for airflow turbulence is formed between two adjacent heat dissipation fins.

[0010] Preferably, the raised bumps, the strip holes, and the gaps between adjacent heat dissipation fins have multiple turbulence effects.

[0011] Preferably, the U-shaped heat-conducting plates are arranged in a staggered pattern within the flow channel, and the top and side surfaces of the U-shaped heat-conducting plates near the flow channel are respectively in close contact with the inner wall of the flow channel.

[0012] Compared with the prior art, this utility model provides a high heat transfer automotive radiator heat dissipation structure, which has the following beneficial effects:

[0013] 1. By using the staggered Z-shaped heat-conducting fins arranged on the inner wall of the flow channel, the coolant flow channel is divided and the contact area between the coolant and the heat-conducting structure is increased. This allows the heat of the coolant in the channel to be quickly transferred to the outer wall of the flow channel and into the heat conduction tube inside the coolant, thus solving the problem of uneven heat conduction inside the tube in the traditional structure.

[0014] 2. The inclined heat dissipation fins, combined with the narrow gaps between adjacent fins, further turbulent the airflow. These three elements work together to create multiple turbulence effects, reducing the thermal boundary layer as the airflow passes through the fins. This allows for more thorough contact between the airflow and the heat dissipation fins, resulting in more complete heat exchange. This solves the problem of insufficient heat exchange contact outside the tube in traditional structures, enhances the turbulence effect and external heat exchange efficiency, and ultimately optimizes the overall heat transfer performance of the radiator by increasing the heat conduction velocity inside the tube and enhancing the external turbulence heat exchange effect.

[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] Example:

[0023] Please see Figure 1 - Figure 4 This embodiment of a high heat transfer automotive radiator cooling structure includes an inlet chamber 1, an outlet chamber 2, a cooling core 3, and an electric fan 4. The inlet chamber 1 and outlet chamber 2 are symmetrically arranged at both ends of the cooling core 3. The electric fan 4 is fixed to the air inlet side of the cooling core 3 to provide airflow to the cooling core 3. The electric fan 4 is bolted to the sealing frame of the cooling core 3 through a bracket, providing airflow for external heat exchange, so that the airflow acts on the cooling fins 7. The cooling core 3 includes multiple parallel flow channels 5, Z-shaped heat-conducting fins 6, and cooling fins 7. Both the inlet chamber 1 and outlet chamber 2 are connected to the air inlet chamber 3. The internal flow channels 5 of the heat dissipation core 3 are connected to form a coolant circulation loop. Both the inlet chamber 1 and the outlet chamber 2 are made of reinforced nylon material, which has both lightweight and corrosion resistance. There is a flow divider inside the inlet chamber 1, which distributes the high-temperature coolant entering the inlet chamber 1 to the flow channels 5. The flow channels 5 are tubular structures that form coolant flow chambers inside. The Z-shaped heat conduction plates 6 are fixed to the inner wall of the flow channels 5 by brazing and are evenly distributed along the length of the flow channels 5. The flow channels 5 are flat tube structures formed by aluminum alloy extrusion. The heat inside the tube is transferred to the outside of the tube through the Z-shaped heat conduction plates 6 and the tube wall.

[0024] The Z-shaped heat-conducting fins 6 are arranged alternately in the flow channel 5. The top and side surfaces of the Z-shaped heat-conducting fins 6 are in close contact with the inner wall of the flow channel 5. The Z-shaped heat-conducting fins 6 are made of aluminum alloy with a thickness of 0.6mm-1.0mm. The spacing between two adjacent Z-shaped heat-conducting fins 6 is 12mm-18mm. Their function is to divide the coolant flow channel, increase the contact area between the coolant and the heat-conducting structure, and directly conduct heat into the coolant, quickly eliminate local hot spots in the pipe, and solve the defect of uneven heat conduction in traditional pipe structures.

[0025] The heat dissipation fins 7 are fixed between the outer walls of two adjacent flow channels 5. The heat dissipation fins 7 are inclined relative to the length direction of the flow channels 5. Several protrusions 8 are integrally formed on the surface of the heat dissipation fins 7. The heat dissipation fins 7 are fixed to the outer walls of the flow channels 5 by brazing. The heat dissipation fins 7 are made of aluminum alloy with a thickness of 0.15mm-0.2mm. The thin design ensures structural strength while reducing airflow resistance. The inclined setting guides the airflow to flow along both sides of the fins after impact, breaking the stable laminar flow that is easily formed by traditional straight fins. A fine protrusion is opened at the center of the protrusion 8. The long strip-shaped hole 9 forms a gap 10 between two adjacent heat dissipation fins 7 for airflow turbulence. The minimum gap 10 between two adjacent heat dissipation fins 7 is 2mm-3mm. The protruding bump 8 can initially impact the airflow to form vortices. The strip-shaped hole 9 allows some airflow to pass through and form a backflow. The narrow gap 10 further enhances the airflow turbulence intensity. The three work together. After the airflow flows in from the direction facing the heat dissipation core 3, it impacts the heat dissipation fins 7 and flows along both sides of them. Multiple turbulences are formed through the protruding bump 8, the strip-shaped hole 9 and the gap 10 between adjacent heat dissipation fins 7, which greatly reduces the thermal boundary layer.

[0026] The heat dissipation core 3 also has end plates at both ends. Multiple flow channels 5 are arranged in parallel and fixed by the end plates. The end plates are brazed to the ends of the flow channels 5 and sealed. The end plates are bolted to the water inlet chamber 1 and the water outlet chamber 2 respectively and are sealed with sealing gaskets.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
