Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a waveform heat dissipation strip and a radiator including the waveform heat dissipation strip. Background Technology

[0002] A radiator is a heat exchange device that reduces the temperature of a heat source through heat exchange. Radiators are widely used in industries such as industry, machinery, electronics, and automobiles. Their main purpose is to dissipate the heat generated by equipment or systems from the heat source to maintain a stable operating temperature and ensure the normal operation of the equipment or system.

[0003] A radiator typically consists of three parts: an inlet chamber, an outlet chamber, and the radiator core. Coolant flows inside the radiator core, while air passes outside the radiator; the hot coolant cools down by dissipating heat to the air, while the cool air warms up by absorbing the heat dissipated by the coolant.

[0004] Most current radiator cores consist of heat pipes and heat fins. Heat pipes are straight tubes located between the inlet and outlet chambers, serving as channels for the coolant. Heat fins provide a larger heat dissipation area. Heat pipes are flat tubes (or channels formed by welding together seals, baffles, and turbulence fins; in this article, "heat pipe" refers to internal fluid channels of various structures) and are welded together with heat fins. This design creates holes in the heat fins that turbulent the airflow, breaking the adhesion layer of flowing air on the surface of the heat fins, thereby increasing the heat dissipation area, improving heat dissipation capacity, and making the radiator low-cost and lightweight. However, current heat fins are usually machined with fin structures. During use, it has been found that although fin structures can improve the heat dissipation capacity of heat fins to some extent, their turbulence effect is still not ideal. This means that the amount of heat carried away by the cool air as it passes through the heat fins is limited, resulting in low heat exchange efficiency, and the heat dissipation effect still needs further improvement. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art as mentioned above, in-depth research was conducted, and after a great deal of creative work, this utility model was completed.

[0006] Specifically, the technical problem to be solved by this utility model is to provide a waveform heat dissipation strip and a heat sink including the waveform heat dissipation strip, so as to solve the technical problem of low heat exchange efficiency and poor heat dissipation effect of the current heat dissipation strip structure.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

The connecting part and the heat dissipation part are provided in a plurality of places, and the plurality of connecting parts and heat dissipation parts are arranged alternately, and an airflow channel is formed between adjacent connecting parts and heat dissipation parts.

[0009] The heat dissipation part is provided with at least one waveform turbulence protrusion along its length direction, and the heat dissipation part is also provided with a waveform groove corresponding to the waveform turbulence protrusion, and the corresponding waveform turbulence protrusion and the waveform groove are respectively provided on both sides of the heat dissipation part.

[0010] As an improved technical solution, the connecting part is located at the top or bottom of the adjacent heat dissipation part, and the connecting parts and the heat dissipation part are in a square wave structure.

[0011] As an improved technical solution, the heat dissipation part is provided with a waveform turbulence protrusion along its length direction, and the peak of the waveform turbulence protrusion is close to the top of the heat dissipation part, and the trough of the waveform turbulence protrusion is close to the bottom of the heat dissipation part.

[0012] As an improved technical solution, the heat dissipation part is provided with two waveform turbulence protrusions along its length direction, both of which are located on one side of the heat dissipation part, and the two waveform grooves are located on the other side of the heat dissipation part.

[0013] As an improved technical solution, the two waveform turbulence protrusions are arranged side by side along the height direction of the heat dissipation part, and the peak of one waveform turbulence protrusion is close to the top of the heat dissipation part, while the trough of the other waveform turbulence protrusion is close to the bottom of the heat dissipation part.

[0014] As an improved technical solution, the two waveform turbulence protrusions are arranged in an intersecting manner, and the peak segment of one waveform turbulence protrusion corresponds to the trough segment of the other waveform turbulence protrusion. The peak segments of both waveform turbulence protrusions are close to the top of the heat dissipation part, and the trough segments of both waveform turbulence protrusions are close to the bottom of the heat dissipation part.

[0015] As an improved technical solution, the heat dissipation part is provided with two waveform turbulence protrusions along its length direction. The two waveform turbulence protrusions are respectively located on both sides of the heat dissipation part, with one waveform turbulence protrusion close to the top of the heat dissipation part and the other waveform turbulence protrusion close to the bottom of the heat dissipation part. The peak segments of the two waveform turbulence protrusions are correspondingly arranged, and the trough segments of the two waveform turbulence protrusions are correspondingly arranged.

[0016] As an improved technical solution, the waveform turbulence protrusion has a sinusoidal structure.

[0017] As an improved technical solution, the waveform turbulence protrusion includes a beveled portion and a flat portion, with two beveled portions and the flat portion located between the two beveled portions, and the beveled portion and the flat portion are integrally formed.

[0018] This utility model also discloses a heat sink, including the waveform heat dissipation strip as described above, and also including heat dissipation pipes. A plurality of heat dissipation pipes and waveform heat dissipation strips are provided, and the plurality of heat dissipation pipes and waveform heat dissipation strips are arranged alternately. The waveform heat dissipation strips are fixedly connected to the heat dissipation pipes through the connecting part.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are:

[0020] The corrugated heat sink has a connecting part for connecting with the heat sink pipe. The heat sink has corrugated turbulence protrusions and corrugated grooves, which increase the heat dissipation area and improve the heat dissipation capacity of the corrugated heat sink. In addition, the corrugated turbulence protrusions have a good turbulence effect. When air passes through the airflow channel, the corrugated turbulence protrusions can disturb the airflow, so that the airflow forms a turbulent layer, thereby greatly improving the heat exchange efficiency of the heat sink. This allows the air to carry away more heat when passing through the corrugated heat sink, thereby further improving the heat dissipation capacity of the corrugated heat sink and greatly improving the heat dissipation effect of the corrugated heat sink.

[0021] This radiator features a corrugated heat dissipation strip that is securely connected to the heat dissipation pipe via a connector, ensuring a strong and reliable connection. The heat dissipation pipe allows for heat conduction between the two components through the connector. Coolant flows through the heat dissipation pipe, transferring heat to the corrugated heat dissipation strip. Air passes through the airflow channel; the hot coolant cools down by dissipating heat through the heat dissipation pipe and the corrugated heat dissipation strip, while the cool air warms up by absorbing the heat dissipated by the coolant. This heat exchange is completed through the corrugated heat dissipation strip, achieving heat dissipation. Furthermore, the structural design of the corrugated heat dissipation strip significantly enhances the radiator's heat dissipation capacity, resulting in excellent heat dissipation performance and high practicality.

[0044] 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.

[0047] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0048] like Figures 1 to 20As shown in the figure, this embodiment provides a waveform heat dissipation strip, including an integrally formed connecting part 1 and a heat dissipation part 2. Both the connecting part 1 and the heat dissipation part 2 are provided in a plurality of places, and the plurality of connecting parts 1 and heat dissipation parts 2 are arranged alternately. An airflow channel is formed between adjacent connecting parts 1 and heat dissipation parts 2, and air passes through the airflow channel and carries away the heat dissipated by the waveform heat dissipation strip.

[0049] like Figures 1 to 20 As shown, the heat dissipation part 2 is provided with at least one wave-shaped turbulence protrusion 3 along its length direction. The heat dissipation part 2 is also provided with a wave-shaped groove 4 corresponding to the wave-shaped turbulence protrusion 3. The corresponding wave-shaped turbulence protrusion 3 and wave-shaped groove 4 are respectively provided on both sides of the heat dissipation part 2. The structural design of the wave-shaped turbulence protrusion 3 and the wave-shaped groove 4 can increase the heat dissipation area of ​​the heat dissipation part 2 and make the wave-shaped heat dissipation strip have a turbulence effect. When the air passes through the airflow channel, a turbulence layer can be formed, thereby greatly improving the heat exchange efficiency of the wave-shaped heat dissipation strip.

[0050] In one embodiment, such as Figures 1 to 4 , Figures 7 to 12 , Figures 15 to 18 As shown, the connecting part 1 is located at the top or bottom of the adjacent heat dissipation part 2, and the connecting parts 1 and heat dissipation parts 2 have a square wave structure. The connecting part 1 is used to weld and fix to the heat dissipation pipe. The heat conduction between the heat dissipation pipe and the wave-shaped heat dissipation strip is realized through the connecting part 1. The square wave structure of the wave-shaped heat dissipation strip increases the contact area between the connecting part 1 and the heat dissipation pipe, making the connection between the heat dissipation pipe and the wave-shaped heat dissipation strip firm and reliable. At the same time, it improves the heat conduction efficiency between the heat dissipation pipe and the wave-shaped heat dissipation strip, facilitates the flow of air in the airflow channel, and provides a reliable guarantee for improving the heat dissipation effect of the radiator.

[0051] In one embodiment, such as Figures 1 to 6 As shown, each heat dissipation section 2 is provided with a wave-shaped turbulence protrusion 3 along its length direction. The crest of the wave-shaped turbulence protrusion 3 is close to the top of the heat dissipation section 2, and the trough of the wave-shaped turbulence protrusion 3 is close to the bottom of the heat dissipation section 2. The wave-shaped turbulence protrusion 3 is located on the same side of the heat dissipation section 2. When the airflow passes through the airflow channel, the wave-shaped turbulence protrusion 3 plays a turbulent role, so that the airflow forms a turbulent layer. The turbulent layer is more conducive to carrying away the heat of the wave-shaped heat dissipation strip, thereby improving the heat dissipation effect of the wave-shaped heat dissipation strip.

[0052] In one embodiment, such as Figures 7 to 14 As shown, each heat dissipation part 2 is provided with two wave-shaped turbulence protrusions 3 along its length direction. Both wave-shaped turbulence protrusions 3 are located on one side of the heat dissipation part 2, and two wave-shaped grooves 4 are located on the other side of the heat dissipation part 2. The design of the two wave-shaped turbulence protrusions 3 increases the heat dissipation area of ​​the wave-shaped heat dissipation strip and improves the turbulence effect on the airflow.

[0053] In one embodiment, such as Figure 7 and Figure 8As shown, two wave-shaped turbulence protrusions 3 are arranged side by side along the height direction of the heat dissipation part 2, and the peak of one wave-shaped turbulence protrusion 3 is close to the top of the heat dissipation part 2, while the trough of the other wave-shaped turbulence protrusion 3 is close to the bottom of the heat dissipation part 2; the two wave-shaped turbulence protrusions 3 are arranged side by side, which has a good turbulence effect on the airflow.

[0054] In one embodiment, such as Figures 9 to 14 As shown, two waveform turbulence protrusions 3 are arranged in an intersecting manner, with the peak of one waveform turbulence protrusion 3 corresponding to the trough of the other waveform turbulence protrusion 3. The peaks of both waveform turbulence protrusions 3 are close to the top of the heat dissipation part 2, and the troughs of both waveform turbulence protrusions 3 are close to the bottom of the heat dissipation part 2. The design of the two waveform turbulence protrusions 3 being arranged in an intersecting manner makes the turbulence effect on the airflow better and the heat dissipation effect better.

[0055] In one embodiment, such as Figures 15 to 20 As shown, each heat dissipation section 2 has two wave-shaped turbulence protrusions 3 along its length. The two wave-shaped turbulence protrusions 3 are located on both sides of the heat dissipation section 2, with one wave-shaped turbulence protrusion 3 near the top of the heat dissipation section 2 and the other wave-shaped turbulence protrusion 3 near the bottom of the heat dissipation section 2. The crests and troughs of the two wave-shaped turbulence protrusions 3 are arranged correspondingly. Compared with the structure where they are arranged on the same side, the two wave-shaped turbulence protrusions 3 are arranged on both sides of the heat dissipation section 2, which has a better turbulence effect on the airflow, higher heat exchange efficiency, and better heat dissipation effect.

[0056] In one embodiment, such as Figures 1 to 20 As shown in the figure, the waveform turbulence protrusion 3 has a sinusoidal structure. The sinusoidal structure of the waveform turbulence protrusion 3 has a good turbulence effect on the airflow when the airflow passes through the airflow channel, which enables the waveform heat dissipation strip to have good heat dissipation performance.

[0057] In one embodiment, such as Figure 6 , Figure 14 and Figure 20 As shown, the waveform turbulence protrusion 3 includes a sloping portion 301 and a flat portion 302. There are two sloping portions 301, and the flat portion 302 is located between the two sloping portions 301. The sloping portions 301 and the flat portion 302 are integrally formed. This waveform turbulence protrusion 3 structure can reduce the impact on the airflow velocity while playing a role in turbulence.

[0058] Based on the above structure, the corrugated heat dissipation strip has a connecting part 1 for connecting with the heat dissipation pipe. The heat dissipation part 2 has corrugated turbulence protrusions 3 and corrugated grooves 4, which increase the heat dissipation area of ​​the heat dissipation part 2 and improve the heat dissipation capacity of the corrugated heat dissipation strip. In addition, the corrugated turbulence protrusions 3 have a good turbulence effect. When air passes through the airflow channel, the corrugated turbulence protrusions 3 can disturb the airflow, so that the airflow forms a turbulent layer, thereby greatly improving the heat exchange efficiency of the heat dissipation part 2. This allows the air to carry away more heat when passing through the corrugated heat dissipation strip, thereby further improving the heat dissipation capacity of the corrugated heat dissipation strip and greatly improving the heat dissipation effect of the corrugated heat dissipation strip.

[0059] This utility model also discloses a radiator, including the corrugated heat dissipation strip as described above, and also including heat dissipation pipes. A plurality of heat dissipation pipes and corrugated heat dissipation strips are provided. The plurality of heat dissipation pipes are evenly arranged and the plurality of heat dissipation pipes and corrugated heat dissipation strips are arranged alternately. The corrugated heat dissipation strips are fixedly connected to the heat dissipation pipes through connecting part 1. The plurality of heat dissipation pipes and corrugated heat dissipation strips arranged alternately form the radiator core.

[0060] The radiator also includes an inlet chamber and an outlet chamber, with the radiator core located between the inlet and outlet chambers. The heat dissipation tubes are flat tubes with both ends connected to the inlet and outlet chambers, respectively.

[0061] Based on the above structure, the corrugated heat dissipation strip is fixedly connected to the heat dissipation pipe through the connecting part 1, making the connection between the corrugated heat dissipation strip and the heat dissipation pipe firm and reliable. The heat dissipation pipe can achieve heat conduction through the connecting part 1. The heat dissipation pipe serves as a channel for the coolant, and the coolant flows through the heat dissipation pipe, conducting heat to the corrugated heat dissipation strip. Air passes through the airflow channel, and the hot coolant becomes cold due to heat dissipation to the air through the heat dissipation pipe and the corrugated heat dissipation strip. The cold air is heated by absorbing the heat dissipated by the coolant, thus completing heat exchange through the corrugated heat dissipation strip and achieving heat dissipation. Moreover, the structural design of the corrugated heat dissipation strip greatly improves the heat dissipation capacity of the radiator, resulting in excellent heat dissipation effect and strong practicality.

[0062] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
