[0002] To meet the growing computing demands, especially in data-intensive and compute-intensive applications, accelerator cards have emerged as a crucial tool for improving the performance of electronic devices. Accelerator cards, also known as computing power cards or AI accelerator cards, are specially designed hardware expansion modules that connect to electronic devices to enhance their processing speed and efficiency.

[0003] In related technologies, accelerator cards use heat sinks and turbo fans for heat dissipation. Due to the turbo fan's airflow characteristics, the air volume and pressure are higher near the outlet, while the air volume and pressure are lower farther away from the outlet. This results in poor heat dissipation from some of the fins, insufficient heat dissipation from some chips in the accelerator card, and thus affects the performance of the entire electronic device. Utility Model Content

[0004] The purpose of the utility model is to provide an accelerator card, aiming to solve the technical problem that the heat dissipation effect of the heat dissipation fins of the accelerator card is poor, the heat dissipation of some chips of the accelerator card is insufficient, and the performance of the electronic equipment is affected.

[0005] In order to achieve the above object, the utility model provides an accelerator card, comprising a heat sink, a turbo fan and a radiator, wherein the turbo fan and the radiator are arranged on the same side of the heat sink along the length direction of the heat sink;

[0006] The radiator includes a first radiating module and a second radiating module, wherein the first radiating module and the second radiating module are adjacently arranged along the width direction of the radiating plate, and the first radiating module and the second radiating module are both composed of a plurality of fins arranged at intervals;

[0007] The radiator is provided with a heat dissipation channel, the heat dissipation channel runs through the first heat dissipation module and the second heat dissipation module, and the heat dissipation channel is at a preset distance from the turbo fan;

[0008] The air outlet of the turbofan faces the first heat dissipation module, and the turbofan is used to generate cooling air so that the cooling air blows toward the first heat dissipation module and from the first heat dissipation module to the second heat dissipation module through the heat dissipation channel.

[0009] In the acceleration card of the present application, the heat dissipation channel penetrates the first heat dissipation module and the second heat dissipation module along the width direction of the heat dissipation plate.

[0010] In the accelerator card of the present application, the heat dissipation channel includes a first channel and a second channel connected to the first channel, the first channel runs through the first heat dissipation module, and the second channel runs through the second heat dissipation module;

[0011] A baffle is provided on a side of the first channel away from the turbofan, and the baffle extends in the direction of the first channel.

[0012] In the acceleration card of the present application, the length of the blocking piece is greater than or equal to the length of the first channel.

[0013] In the acceleration card of the present application, the blocking piece extends from an end away from the second heat dissipation module to an end close to the second heat dissipation module in a direction gradually away from the turbo fan.

[0014] In the acceleration card of the present application, in the length direction of the heat dissipation plate, the width of the second channel is greater than the width of the first channel.

[0015] In the accelerator card of the present application, the width of the second channel is twice the width of the first channel.

[0016] In the acceleration card of the present application, the heat dissipation channel is provided at a middle position of the radiator along the height direction of the heat dissipation plate.

[0017] In the acceleration card of the present application, in the height direction of the heat dissipation plate, the height of the blocking piece is smaller than the height of the first heat dissipation module.

[0019] In the accelerator card of the present application, the first heat dissipation module and the second heat dissipation module are designed as an integral whole.

[0020] In the acceleration card of the present application, the acceleration card includes a guide plate, which surrounds the turbofan and is spaced apart from the turbofan. The first end of the guide plate extends toward the outside of the first heat dissipation module, and the second end of the guide plate extends toward the outside of the second heat dissipation module.

[0021] The utility model provides an accelerator card, which has the following beneficial effects:

[0022] The accelerator card of the present invention includes a heat sink, a turbofan, and a radiator. The radiator includes a first heat sink module and a second heat sink module. A heat sink channel is provided on the radiator, which runs through both the first and second heat sink modules. The cooling air generated by the turbofan is blown from the air outlet to the first heat sink module, wherein most of the cooling air flows through the fins of the first heat sink module, thereby cooling the first heat sink module. At the same time, a portion of the cooling air enters the heat sink channel and blows along the channel to the fins of the second heat sink module, thereby cooling the second heat sink module. In this way, both the first and second heat sink modules can obtain a relatively uniform amount of cooling air, achieving a balanced heat dissipation effect. A certain preset distance is maintained between the heat sink channel and the turbofan, which can prevent the heat sink channel from being too close to the turbofan, thereby increasing wind resistance and reducing heat dissipation efficiency, and also prevent the heat sink channel from being too far from the turbofan, thereby preventing insufficient cooling air from flowing through the second heat sink module.

[0031] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. used in the present invention to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices and elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of this utility model, it should be understood that the terms "first," "second," etc. are used to describe various types of information, but such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information without departing from the scope of this utility model.

[0034] In current technology, accelerator cards are limited by the size of standard cards, limiting the length, width, and height of the heat sink fins. This makes heat dissipation difficult. Currently, the industry generally uses flat turbofans to cool the radiator. However, the air volume and pressure are higher near the air outlet, while those farther away are lower, resulting in poor heat dissipation from the fins farther away.

[0035] Some technologies increase the distance between the turbofan and the heat sink fins so that the turbofan's airflow is directed toward all the heat sink fins as much as possible, ensuring sufficient space for uniform airflow and thus even heat dissipation across all the heat sinks. However, since there are no heat sink fins near the turbofan's air outlet, the heat dissipation area in this area is insufficient, resulting in unsatisfactory heat dissipation in this area.

[0036] Other technologies place cooling fans on top of the heat sink fins, blowing directly over them for cooling. However, this arrangement increases the overall height and thickness of the accelerator card, taking up a correspondingly larger space and making it difficult to meet practical installation requirements. Furthermore, placing the cooling fan on top of the heat sink fins forces airflow to enter from the top and exit from both sides of the fins, which is inconsistent with the airflow direction from the front to the back of the accelerator card server. This can easily cause turbulence and affect the overall heat dissipation performance of the electronic device.

[0037] like Figures 1 to 5As shown, an embodiment of the present invention provides an accelerator card 100, comprising a heat sink 1, a turbofan 2 and a radiator 3, wherein the turbofan 2 and the radiator 3 are arranged on the same side of the heat sink 1 along the length direction of the heat sink 1; the radiator 3 comprises a first heat sink module 31 and a second heat sink module 32, wherein the first heat sink module 31 and the second heat sink module 32 are adjacently arranged along the width direction of the heat sink 1, and the first heat sink module 31 and the second heat sink module 32 are both composed of a plurality of spaced fins; the radiator 3 is provided with a heat dissipation channel 33, which passes through the first heat sink module 31 and the second heat sink module 32, and the heat dissipation channel 33 is at a preset distance from the turbofan 2; wherein the air outlet 20 of the turbofan 2 faces the first heat sink module 31, and the turbofan 2 is used to generate cooling air so that the cooling air is blown toward the first heat sink module 31 and from the first heat sink module 31 to the second heat sink module 32 through the heat dissipation channel 33.

[0038] It should be noted that the length direction of the heat sink 1 (or the accelerator card 100 ) is the X direction, the width direction of the heat sink 1 is the Y direction, and the height direction of the heat sink 1 is the Z direction, and the three directions are perpendicular to each other.

[0039] In this embodiment, if Figure 2 As shown, the bottom surface of the heat sink 1 is equipped with chips, which are heat sources that need to be dissipated. The turbofan 2 and the heat sink 3 are located on the same side of the heat sink 1 along its length (i.e., the X direction). The heat sink 3 is divided into two parts: a first heat sink module 31 on the left and a second heat sink module 32 on the right.

[0040] In actual application, the first heat dissipation module 31 and the second heat dissipation module 32 are integrally designed fin structures, and the multiple fin heat dissipation plates 1 are arranged in a vertical array in the longitudinal direction (i.e., the X direction). Since the air outlet 20 of the turbofan 2 is facing the first heat dissipation module 31 (the left module), most of the cooling air generated by the turbofan 2 is mainly blown toward the first heat dissipation module 31, and only a small amount of cooling air is blown toward the second heat dissipation module 32 (the right module), resulting in uneven heat dissipation between the first heat dissipation module 31 and the second heat dissipation module 32. The heat dissipation effect of the second heat dissipation module 32 is worse than that of the first heat dissipation module 31. Therefore, although the fins of the first heat dissipation module 31 and the second heat dissipation module 32 have the same heat dissipation structure, due to the different heat dissipation performance of the two modules, this embodiment divides them into the first heat dissipation module 31 and the second heat dissipation module 32.

[0041] During production, the fins of the first heat dissipation module 31 and the fins of the second heat dissipation module 32 are arranged together on the heat sink 1 to form an integrated structure. The purpose of providing the fins is to increase the heat dissipation area of ​​the radiator 3 and improve the heat conduction efficiency. The cooling air generated by the turbofan 2 flows through the fins of the radiator 3, forming convection cooling between the fins to cool the radiator 3.

[0042] Based on the above technical solution, this embodiment provides a heat dissipation channel 33 in the radiator 3 that runs through both the first heat dissipation module 31 and the second heat dissipation module 32. The cooling air generated by the turbofan 2 is blown from the air outlet 20 toward the first heat dissipation module 31. Most of the cooling air flows through the fins of the first heat dissipation module 31, cooling the first heat dissipation module 31. At the same time, some of the cooling air enters the heat dissipation channel 33 and flows along it toward the fins of the second heat dissipation module 32, cooling the second heat dissipation module 32. This ensures that both the first heat dissipation module 31 and the second heat dissipation module 32 receive a relatively uniform amount of cooling air, achieving uniform heat dissipation.

[0043] In this embodiment, if Figure 3 and Figure 4 As shown, the preset distance L between the heat dissipation channel 33 and the turbofan 2 is controlled within a certain range according to the actual overall size of the accelerator card 100. The preset distance L is controlled within a certain range to the ratio of the preset distance L to the fin length of the radiator 3. The preset distance L should be neither too large nor too small. This is to avoid the increase in wind resistance and the decrease in heat dissipation efficiency caused by the distance between the heat dissipation channel 33 and the turbofan 2 being too small, and the insufficient cooling air flow through the second heat dissipation module 32 caused by the distance between the heat dissipation channel 33 and the turbofan 2 being too large.

[0044] It should be further explained that the above “the distance between the heat dissipation channel 33 and the turbofan 2 is too large, resulting in insufficient cooling air flow through the second heat dissipation module 32” does not mean that the cooling air flow through the heat dissipation channel 33 to the second heat dissipation module 32 is insufficient, but rather that the cooling air flow through the fins of the second heat dissipation module 32 that does not pass through the heat dissipation channel 33 is insufficient. Figure 4 As shown, the fins of the second heat dissipation module 32 are divided into two sections, front and back, by the heat dissipation channel 33. The front section fins (i.e., the side close to the turbofan 2) are not passed through by the cooling air passing through the heat dissipation channel 33, and the rear section fins (i.e., the side away from the turbofan 2) are passed through by the cooling air passing through the heat dissipation channel 33. If the distance between the heat dissipation channel 33 and the turbofan 2 is too large, the front section fins will occupy a larger area. Since the heat dissipation effect of the front section fins is relatively poor, the overall cooling air volume passing through the second heat dissipation module 32 will be insufficient.

[0045] In this embodiment, the layout of the heat dissipation channel 33 can be flexibly designed. Specifically, the heat dissipation channel 33 can extend between the first heat dissipation module 31 and the second heat dissipation module 32 in a straight line or a broken line, or can extend between the first heat dissipation module 31 and the second heat dissipation module 32 in a curved path. There are no specific restrictions on the specific shape and extension direction of the heat dissipation channel 33. The key is that as long as a portion of the cooling air can be directed from the first heat dissipation module 31 to the second heat dissipation module 32 through the heat dissipation channel 33, uniform cooling of the entire radiator 3 can be achieved, thereby improving the heat dissipation performance of the accelerator card 100.

[0046] It can be understood that in this embodiment, the heat dissipation channel 33 can be set inside the radiator 3 or at the top or bottom of the radiator 3, as long as a part of the cooling air can be guided from the first heat dissipation module 31 to the second heat dissipation module 32 through the heat dissipation channel 33.

[0047] In some embodiments, as Figure 4 As shown, the heat dissipation channel 33 passes through the first heat dissipation module 31 and the second heat dissipation module 32 along the width direction (ie, the Y direction) of the heat dissipation plate 1 .

[0048] Exemplarily, the heat dissipation channel 33 extends in a straight line along the Y direction between the first heat dissipation module 31 and the second heat dissipation module 32 , the flow path of the cooling air is the shortest, and the structure is relatively simple, so as to facilitate mold opening and molding.

[0049] Exemplarily, the heat dissipation channel 33 extends along the Y direction in a curved path between the first heat dissipation module 31 and the second heat dissipation module 32 , so the flow path of the cooling air is relatively long, and the cooling effect is better.

[0050] In some embodiments, as Figure 4 as well as Figure 5 As shown, the heat dissipation channel 33 includes a first channel 331 and a second channel 332 connected to the first channel 331. The first channel 331 passes through the first heat dissipation module 31, and the second channel 332 passes through the second heat dissipation module 32. A baffle 34 is provided on the side of the first channel 331 away from the turbofan 2, and the baffle 34 extends in the direction of the first channel 331.

[0051] Specifically, a baffle 34 is provided inside the first channel 331. The main function of the baffle 34 is to adjust the flow direction of the cooling air and guide part of the cooling air to the second channel 332. When the cooling air blows from the air outlet 20 toward the fins of the first heat dissipation module 31, the cooling air enters the first channel 331. At this time, the cooling air is divided into two main flow paths. One part of the cooling air bypasses the obstruction of the baffle 34 and continues to flow forward along the predetermined path from the upper or lower end of the baffle 34 through the fins of the first heat dissipation module 31. The temperature of the first heat dissipation module 31 is reduced through the heat exchange process, thereby cooling the first heat dissipation module 31. The other part of the cooling air directly hits the baffle 34, is intercepted by the baffle 34, and changes its flow direction, guiding it from the first channel 331 to the second channel 332. In the second channel 332, the cooling air continues to flow forward through the fins of the second heat dissipation module 32, thereby cooling the second heat dissipation module 32. This embodiment adopts the design of the baffle 34 to adjust the flow direction of a portion of the cooling air so that the cooling air can flow evenly between the two heat dissipation modules, thereby maximizing the heat dissipation performance.

[0052] The material of the baffle 34 includes but is not limited to plastic, rubber or metal alloy.

[0053] In some embodiments, the baffle 34 fits against the inner wall of the first channel 331 to form a plate-like structure, and the length and width of the baffle 34 can be adjusted according to the size of the first channel 331. During production, the baffle 34 and the fin can be manufactured through a one-step molding process.

[0054] In some embodiments, the first channel 331 and the second channel 332 are an integrally formed structure. The first channel 331 and the second channel 332 are designed to be connected as an integrally formed structure to ensure that the cooling air flows between the two heat dissipation modules.

[0055] When producing the radiator 3 , the heat dissipation channel 33 can be manufactured through a one-time molding process (such as stamping, casting, etc.), reducing the complexity of manufacturing.

[0056] In some embodiments, as Figure 4 as well as Figure 5 As shown, the length of the blocking piece 34 is greater than or equal to the length of the first channel 331 .

[0057] Exemplarily, the length of the baffle 34 is the same as that of the first channel 331 , so that the cooling air can be completely guided by the baffle 34 when flowing out of the first channel 331 , and the baffle 34 can continuously and uninterruptedly guide the airflow over the entire length.

[0058] Exemplarily, the length of the baffle 34 may be slightly greater than the length of the first channel 331 , further intercepting the cooling air in the first channel 332 and guiding it to the second channel 332 .

[0059] It is understandable that if, on the other hand, the length of the baffle 34 is smaller than the length of the first channel 331, when the cooling air flows through the first channel 331, a portion of the air continues to flow forward through the gap between the baffle 34 and the fins, causing the airflow entering the second channel 332 to be relatively small, affecting the cooling of the second heat dissipation module 32.

[0060] In some embodiments, the blocking piece 34 extends from an end away from the second heat dissipation module 32 to an end close to the second heat dissipation module 32 in a direction gradually away from the turbofan 2 .

[0061] Specifically, if Figure 5 As shown, the baffle 34 gradually deviates from the turbofan 2 from left to right, that is, the length direction of the baffle 34 has a certain angle with the center line direction of the first channel 331, and this angle can be an acute angle of 0-15°, so that the first channel 331 gradually expands from left to right, which is more conducive to reducing the resistance of airflow when passing through, and is conducive to guiding the cooling air from the first channel 332 to the second channel 332. When the cooling air encounters the baffle 34, due to its gradually deviating design, the airflow will naturally be guided to the second channel 332.

[0062] It is understandable that if the baffle 34 is not set in this way, but the baffle 34 is set gradually away from the turbofan 2 from right to left, so that the first channel 331 gradually expands from right to left, this will cause this part of the cooling air to be guided out of the first heat dissipation module 31 from the left outlet of the first channel 332, and the cooling of the second heat dissipation module 32 will not be achieved.

[0063] In some embodiments, as Figure 5 As shown, in the length direction of the heat dissipation plate 1 , the width of the second channel 332 is greater than the width of the first channel 331 .

[0064] Specifically, the width of the first channel 331 is W1, and the width of the second channel 332 is W2. Along the length of the heat sink 1 (i.e., the X-direction), W1 is smaller than W2. The entire heat dissipation channel 33 expands from left to right, allowing the cooling air to flow smoothly from the first channel 331 into the second channel 332 and diffuse into the second channel 332. When the cooling air is directed from the first channel 332 to the second channel 332, a buffer is formed in the second channel 332 area, preventing damage to the fins caused by excessive cooling air flow.

[0065] In one embodiment, the width of the second channel 332 is twice the width of the first channel 331 .

[0066] Specifically, in this embodiment, the width W2 of the second channel 332 is designed to be twice the width W2 of the first channel 331, which ensures that the cooling air is more evenly distributed between the two heat dissipation modules and avoids insufficient cooling air flow of the second heat dissipation module 32 due to an excessively large width ratio.

[0067] In some embodiments, as Figure 1 and Figure 4 As shown, the heat dissipation channel 33 is provided at the middle position of the radiator 3 along the height direction (ie, the Z direction) of the heat dissipation plate 1 .

[0068] It is understandable that if the heat dissipation channel 33 is located at the top of the radiator 3, the cooling air flowing through the fins of the two heat dissipation modules will easily cause poor heat dissipation at the bottom of the fins. Similarly, if the heat dissipation channel 33 is located at the bottom of the radiator 3, the cooling air flowing through the fins of the two heat dissipation modules will cause poor heat dissipation at the top of the fins. In this embodiment, the heat dissipation channel 2 is placed in the middle of the radiator 3 to ensure that the cooling air can maintain a relatively uniform cooling capacity when flowing through the fins. Whether it is the top or the bottom of the fins, sufficient cooling air volume is obtained, thereby achieving uniform heat dissipation of the radiator 3.

[0069] In some embodiments, as Figure 4 and Figure 5 As shown, in the height direction of the heat dissipation plate 1 , the height of the blocking piece 34 is smaller than the height of the first heat dissipation module 31 .

[0070] Specifically, on the basis of placing the heat dissipation channel 2 in the middle position of the radiator 3, the height of the baffle 34 is less than the height of the first heat dissipation module 31, that is, it is not greater than or equal to the height of the first heat dissipation module 31, thereby avoiding the baffle 34 blocking the cooling air flow flowing through the fins of the first heat dissipation module 31, and preventing the baffle 34 from affecting the heat dissipation effect of the first heat dissipation module 31.

[0071] In some embodiments, the height of the blocking piece 34 is greater than one quarter of the height of the first heat dissipation module 31 and less than one half of the height of the first heat dissipation module 31 .

[0072] Specifically, based on the placement of the heat dissipation channel 2 in the middle of the radiator 3, the height of the baffle 34 is proportional to the height of the first heat dissipation module 31. When the height of the baffle 34 is greater than half the height of the first heat dissipation module 31, the baffle 34 is too high, which will reduce the cooling airflow through the fins of the first heat dissipation module 31, affecting the heat dissipation effect of the first heat dissipation module 31. When the height of the baffle 34 is less than one-quarter the height of the first heat dissipation module 31, the baffle 34 is too low, which will reduce the cooling airflow entering the second channel 332 and flowing through the fins of the second heat dissipation module 32, affecting the heat dissipation effect of the second heat dissipation module 32.

[0073] In this embodiment, the height of the baffle 34 is adjusted to be greater than one-fourth of the height of the first heat dissipation module 31 and less than one-half of the height of the first heat dissipation module 31, thereby rationally optimizing the distribution ratio of the airflow between the first heat dissipation module 31 and the second heat dissipation module 32, so that both heat dissipation modules can obtain sufficient cooling air volume, thereby improving the heat dissipation performance of the entire radiator.

[0074] In one embodiment, the height of the blocking piece 34 is equal to one third of the height of the first heat dissipation module 31 .

[0075] Specifically, the height of the baffle 34 is equal to or approximately equal to one-third of the height of the first heat dissipation module 31, so that the cooling air flow is reasonably distributed between the first heat dissipation module 31 and the second heat dissipation module 32. This will not significantly reduce the cooling air volume of the first heat dissipation module 31, but will also ensure that the second heat dissipation module 32 obtains sufficient cooling air volume to achieve uniform heat dissipation.

[0076] In some embodiments, as Figure 4 as well as Figure 5 As shown, the first heat dissipation module 31 and the second heat dissipation module 32 are designed as an integral whole, and the fins of the first heat dissipation module 31 and the fins of the second heat dissipation module 32 are arranged together on the heat dissipation plate 1 to form an integral heat dissipation fin structure.

[0077] In other embodiments, the first heat dissipation module 31 and the second heat dissipation module 32 may also have a certain interval.

[0078] In some embodiments, as Figures 1 to 4 As shown, the radiator 3 includes a guide plate 4, which surrounds the turbofan 2 and is spaced apart from the turbofan 2. The first end of the guide plate 4 extends toward the outside of the first heat dissipation module 31, and the second end of the guide plate 4 extends toward the outside of the second heat dissipation module 32.

[0079] In this embodiment, the deflector 4 can be mounted on the heat sink 1 by bolts, snaps, or other fixing methods, and is located on the same side of the heat sink 1 as the turbofan 2. During installation, an appropriate spacing is maintained between the deflector 4, the turbofan 2, and the heat sink module.

[0080] The deflector 4 is curved to match the shape of the turbofan 2. A portion of the deflector surrounds the outer circumference of the turbofan 2, while the left side extends to and connects to the first heat dissipation module 31. The left side of the deflector 4 encloses the air outlet 20 of the turbofan 2, directing cooling air from the air outlet 20 through the left side of the deflector into the fins of the first heat dissipation module 31. The right side of the deflector 4 extends to and connects to the second heat dissipation module 32, directing another portion of the cooling air through the right side of the deflector into the fins of the second heat dissipation module 32, thereby partially cooling the radiator 3.
