Therefore, a cooling system is required. Currently, the cooling system removes heat through the circulation of coolant. However, this cooling method is slow and inefficient, shortening the service life of the engine or fuel cell stack. Summary of the Invention

[0055] Although the present application can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the application and is not intended to limit the application to what is described herein.

In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations.

These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, the directional indications will also change accordingly.

[0058] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of this application will be more comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The accompanying drawings are merely schematic illustrations of the present application and are not necessarily drawn to scale. Identical reference numerals in the figures indicate identical or similar parts, and thus repeated descriptions thereof will be omitted.

[0059] The preferred embodiments of the present application are further described in detail below in conjunction with the drawings of this specification.

[0060] See Figure 1 and Figure 2 As shown, the present application provides a heat dissipation device 1, which is applied to a vehicle, and is mainly used in the cooling system of the vehicle. After the coolant cools the engine 2 or the electric propulsion, it flows to the heat dissipation device 1 to complete the heat dissipation. In a fuel vehicle, the engine 2 is the power source of the vehicle. In an electric new energy vehicle, the battery stack is the power source of the vehicle. The cooling system can also cool the installed engine 2 and the battery stack at the same time.

[0061] The heat dissipation device 1 comprises a heat dissipation pipe 10, an air inlet pipe 20 and an air outlet pipe 30. The air inlet pipe 20 and the air outlet pipe 30 are both connected to the heat dissipation pipe 10 to take away the heat of the heat dissipation pipe 10.

[0062] Among them, the heat dissipation pipe 10 includes an inner tube 110 and an outer tube 120. The outer tube 120 is sleeved on the inner tube 110. The inner tube 110 is used for the circulation of coolant. An air flow channel 101 is formed between the inner wall surface of the outer tube 120 and the outer wall surface of the inner tube 110. There is a gap between the inner tube 110 and the outer tube 120, and this gap refers to the air flow channel 101. The inlet and outlet of the inner tube 110 are respectively connected to the heat dissipation object, and the heat dissipation object here mainly refers to the engine 2 or the battery stack. The outer tube 120 is partially sleeved on the outer wall surface of the inner tube 110. In order to make the sleeve area of ​​the outer tube 120 and the inner tube 110 larger, the outer tube 120 can be sleeved at the inlet of the inner tube 110 and extend along the outer wall surface of the inner tube 110 to the outlet position of the inner tube 110.

[0063] The air inlet duct 20 is connected to the outer tube 120, and the lumen of the air inlet duct 20 is in communication with the air flow channel 101. The air outlet duct 30 is connected to the outer tube 120, and the lumen of the air outlet duct 30 is in communication with the air flow channel 101. The air inlet duct 20 is used to introduce cooling air, which flows along the air flow channel 101 and is discharged from the air outlet duct 30. The coolant releases heat absorbed from the engine 2 or the fuel cell stack to the inner tube 110. As the cooling air flows in the air flow channel 101, heat exchange occurs between the cooling air and the inner tube 110, transferring heat from the inner tube 110 to the cooling air. As a result, the heat of the coolant is exchanged with the cooling air, which then flows in the air flow channel 101 and carries away the exchanged heat.

[0064] In the technical solution of this embodiment, the inner tube 110 of the heat dissipation pipe 10 is used to circulate the coolant. After completing the heat exchange with the cooling object, the coolant flows to the heat dissipation pipe 10 and dissipates the heat at the heat dissipation pipe 10. An air flow channel 101 is formed between the outer tube 120 and the inner tube 110. The cooling air enters the air flow channel 101 from the air inlet pipe 20, and takes away the heat emitted from the surface of the inner tube 110. The cooling air is discharged from the air outlet pipe 30 after circulating in the air flow channel 101. It can be seen from this that the technical solution, by accelerating the air flow on the outer wall of the inner tube 110, more effectively achieves heat dissipation and ensures the normal use of the engine 2 or the battery stack.

[0065] Furthermore, through the provision of the air flow channel 101, cooling air can flow through smaller gaps. The same volume of air can obtain a higher air pressure due to the smaller space, making the air flow faster.

[0066] In addition, the air flow channel 101 is extended along the outer wall of the inner tube 110, so that the cooling air also flows along the air flow channel 101 of the specified path, so that the cooling air acts more concentratedly around the outer wall of the inner tube 110, thereby fully realizing heat exchange.

[0067] In order to achieve a better heat dissipation effect, multiple air inlet pipes 20 are provided, and the multiple air inlet pipes 20 are spaced apart. In other words, the air flow channel 101 can have multiple air inlets. The multiple air inlet pipes 20 function simultaneously, allowing more air to enter the air flow channel 101, accelerating the flow of air in the air flow channel 101, and removing more heat.

[0068] In addition, it should be noted that when only one inlet pipe and one outlet pipe 30 are provided, the inlet pipe 20 can be placed at the outlet of the inner tube 110, and the outlet pipe 30 can be placed at the inlet of the inner tube 110. As can be seen, the coolant flows through the inner tube 110 from the inlet to the outlet of the inner tube 110, while the airflow in the airflow channel 101 flows from the outlet to the inlet of the inner tube 110. This allows the coolant and cooling air to flow in opposite directions, relative to each other, achieving a better cooling effect than if they flow in the same direction.

[0069] To enhance heat dissipation, the heat pipe 10 includes multiple curved sections 102, each connected end-to-end. The air inlet pipe 20 is connected to one of the curved sections 102, and the air outlet pipe 30 is connected to the curved section 102 further away from the air inlet pipe 20. The provision of multiple curved sections 102 increases the outer surface area of ​​the inner tube 110, allowing the outer surface of the inner tube 110 to have greater contact with air within a limited space. Similarly, the extended length of the airflow channel 101 is also increased, allowing more cooling air to circulate within the channel 101, increasing contact between the cooling air and the outer surface of the inner tube 110, and thus enhancing heat dissipation.

[0070] See Figure 3 As shown, in order to allow more cooling air to enter the air flow channel 101, the heat dissipation device 1 further includes an air-assisting structure 40, which includes an air inlet box 410, a cold air duct 420, and a natural air duct 430. The cold air duct 420 and the natural air duct 430 are both connected to the air inlet box 410, which is used to store some air. The air inlet box 410 acts as a buffer for the airflow in the cold air duct 420 and the natural air duct 430 to enter the air flow channel 101.

[0071] The air intake box 410 is arranged at the air inlet, and the air intake box 410 is provided with an air intake hole, which is arranged facing the air inlet of the air inlet pipe 20; generally speaking, the opening area of ​​the air intake hole is smaller than the opening area of ​​the air inlet, and the opening area of ​​the air intake hole is smaller, which can increase a certain air pressure when the airflow passes through, thereby improving the airflow rate.

[0072] The cold air duct 420 and the natural air duct 430 are respectively provided at both ends of the air intake box 410. The cold air duct 420 is used to provide the vehicle with cold air, which mainly comes from the vehicle's refrigeration system, while the natural air duct 430 is used to provide natural air, which comes from the ambient air. Generally, the temperature of the cold air is lower than that of the natural air.

[0073] The vehicle is provided with a refrigeration system that can provide a cold air flow, and the cold air duct 420 is connected to the vehicle's refrigeration system. Since the temperature of the cold air flow is relatively low, the cold air flow provided by the refrigeration system flows into the air flow channel 101, which can achieve better cooling and heat dissipation effects.

[0074] In addition, the refrigeration system consumes a certain amount of energy during operation. To save energy, cooling can be performed by using the natural airflow provided by the natural air duct 430. For example, when the vehicle is driving, the inlet of the natural air duct 430 is arranged to face the wind, so that the natural airflow will flow along the natural air duct 430 into the air flow channel 101.

[0075] To flexibly adjust the use of cold airflow and natural airflow, the air inlet includes a first air inlet 411a and a second air inlet 411b. The first air inlet 411a and the second air inlet 411b are spaced apart. The first air inlet 411a corresponds to the cold airflow and is used to introduce cold airflow. The second air inlet 411b corresponds to the natural airflow and is used to introduce natural airflow.

[0076] The wind-assisting structure 40 also includes a partition assembly 450, which is arranged in the air intake box 410. The partition assembly 450 divides the air intake box 410 to form a first air chamber 412 and a second air chamber 413. The first air chamber 412 is connected to the cold air duct 420, and the second air chamber 413 is connected to the natural air duct 430. The partition assembly 450 has a first position that blocks the first air intake hole 411a and a second position that blocks the second air intake hole 411b. The partition assembly 450 moves between the first position and the second position.

[0077] By moving the partition assembly 450, in the first position, the partition assembly 450 blocks the first air inlet hole 411a, so that the cold air cannot enter the air flow channel 101 through the first air inlet hole 411a. At this time, the second air inlet hole 411b is open, allowing natural air to enter the air flow channel 101, thereby cooling the inner tube 110 and saving energy.

[0078] When the partition assembly 450 moves to the second position, it blocks the second air inlet hole 411b, preventing natural air from entering the airflow channel 101 through the second air inlet hole 411b. At this time, the first air inlet hole 411a is open, allowing cold air to enter the airflow channel 101, thereby cooling the inner tube 110. Due to the lower temperature of the cold air, a better cooling effect can be achieved.

[0079] It should be noted that the partition assembly 450 can also be positioned anywhere between the first and second positions, allowing the first air inlet 411a and the second air inlet 411b to be both open or partially open. In this case, the cold airflow and the natural airflow simultaneously enter the airflow channel 101, mixing together to reduce the temperature, thereby saving energy and achieving a good cooling effect.

[0080] See Figure 3 and Figure 4As shown, in order to better realize the switching between natural airflow and cold airflow, the wind-assisting structure 40 includes a partition plate 460, which separates the first air chamber 412 and the second air chamber 413; the partition plate 460 is fixed in the air intake box 410, and the position of the partition plate 460 is fixed.

[0081] The partition assembly 450 includes a connecting rod 451, a first movable plate 452, and a second movable plate 453. One end of the connecting rod 451 is connected to the first movable plate 452, and the other end is connected to the second movable plate 453.

[0082] Specifically, the connecting rod 451 is passed through the partition plate 460 and is movably connected to the partition plate 460; the connecting rod 451 can move along the passing direction. The first movable plate 452 is provided in the first air chamber 412, is connected to the connecting rod 451, and abuts against the side wall of the first air chamber 412; the plate surface of the first movable plate 452 is parallel to the plate surface of the partition plate 460, and when the connecting rod 451 moves, the first movable plate 452 also moves therewith. The side of the first movable plate 452 abuts against the side wall of the first air chamber 412. When the connecting rod 451 moves toward the first air chamber 412, the first movable plate 452 moves in a direction away from the partition plate 460. As the first movable plate 452 moves, the connection between the first air inlet 411a and the cold air duct 420 is cut off by the first movable plate 452.

[0083] The second movable plate 453 is located in the second air chamber 413 and is connected to the connecting rod 451. The surface of the second movable plate 453 is parallel to the surface of the partition plate 460. When the connecting rod 451 moves, the second movable plate 453 moves with it. The side of the second movable plate 453 abuts the sidewall of the second air chamber 413. When the connecting rod 451 moves toward the second air chamber 413, the second movable plate 453 moves away from the partition plate 460. As the second movable plate 453 moves, the connection between the second air inlet 411b and the natural air duct 430 is cut off by the second movable plate 453.

[0084] It should be emphasized that, to conserve thrust, the outlet of the cold air duct 420 is positioned directly opposite the first movable plate 452. This allows the cold air flow from the cold air duct 420 to act perpendicularly on the first movable plate 452, thereby pushing the first movable plate 452 to move. Similarly, the natural air duct 430 is also positioned directly opposite the second movable plate 453. This allows the natural air flow from the natural air duct 430 to act perpendicularly on the second movable plate 453, thereby pushing the second movable plate 453 to move.

[0085] To facilitate switching of the partition assembly 450 between the first position and the second position, the partition assembly 450 further includes: a first elastic member 454, a shielding plate 455, and an adjustment plate 456. The first elastic member 454 is disposed between the first movable plate 452 and the partition plate 460; the first position can be understood as the position in a natural state, in which natural airflow is used to cool the inner tube 110. When cold airflow is required to cool the air, the refrigeration system operates, generating a cold airflow that impacts the first air chamber 412. As the pressure in the first air chamber 412 continues to accumulate, the first movable plate 452 is pushed, the first air inlet 411a gradually opens, and the cold airflow flows into the airflow channel 101. The first elastic member 454 can be a spring.

[0086] During this process, the first movable plate 452 moves toward the partition plate 460, causing the partition assembly 450 to switch to the second position. The first elastic member 454 is compressed, generating a restoring force. When the cold airflow is not cooling, the refrigeration system no longer inflates the first air chamber 412. The first elastic member 454 recovers its deformation, driving the first movable plate 452 away from the partition plate 460, and the partition assembly 450 moves to the first position. Thus, the partition assembly 450 completes the switch between the first and second positions.

[0087] In addition, the following solutions can be used to block the second air inlet 411b:

[0088] The shielding plate 455 is movably arranged on the side wall of the second air chamber 413 and is arranged adjacent to the second air inlet hole 411b; the shielding plate 455 can slide along the side wall of the second air chamber 413. As the shielding plate 455 slides, it gradually approaches the second air inlet hole 411b, thereby completing the covering of the second air inlet hole 411b until the second air inlet hole 411b is blocked.

[0089] The adjustment plate 456 is connected to the second movable plate 453 and is arranged facing the baffle plate 455. The opposite surfaces of the adjustment plate 456 and the baffle plate 455 are both arranged with serrations; at this time, there is a gap between the end of the second movable plate 453 away from the baffle plate 455 and the side wall surface of the second air chamber 413, and the gap is for the circulation of natural airflow.

[0090] The air-assisting structure 40 also includes an adjustment wheel 470, which is fixed between the adjustment plate 456 and the shielding plate 455. The adjustment wheel 470 engages with the serrated surfaces of the adjustment plate 456 and the shielding plate 455, respectively. When the first movable plate 452 moves in response to air pressure, the connecting rod 451 also moves synchronously. Driven by the connecting rod 451, the second movable plate 453 moves away from the partition plate 460. The adjustment plate 456 also moves with the second movable plate 453. As the adjustment plate 456 moves downward, the adjustment wheel 470 rotates clockwise. This clockwise rotation of the adjustment wheel 470 drives the shielding plate 455 upward, thereby gradually blocking the second air inlet 411b.

[0091] Similarly, when the second movable plate 453 is impacted by natural airflow, or under the action of the restoring force of the first elastic member 454, the second movable plate 453 moves upward, and the adjusting wheel 470 rotates counterclockwise. When the adjusting wheel 470 rotates counterclockwise, it drives the shielding plate 455 to move downward, and the second air inlet 411b gradually opens.

[0092] It can be seen from the above embodiments that, under the action of the airflow impact force, different forces can be generated on the second movable plate 453 , so that the shielding plate 455 can be adjusted to block different areas of the second air inlet 411 b .

[0093] See Figure 5 As shown, when the coolant in the inner tube 110 is cooled, the coolant may react chemically with the material in the tube wall during the long-term flow process, generating some insoluble solid impurities. The long-term accumulation of these solid impurities will clog the pipeline, causing the cooling system to fail to work effectively. To this end, the heat dissipation device 1 also includes a filter assembly 50, which is used to filter impurities in the coolant. The filter assembly 50 includes: a filter box 510, a drainage pipe 520, a drain pipe 530 and a filter cartridge 540. The drainage pipe 520 drains the coolant to the filter box 510, the filter cartridge 540 filters the coolant, and the filtered coolant is discharged from the drain pipe 530.

[0094] Specifically, one end of the drainage pipe 520 is connected to the inner tube 110, and the other end is connected to the filter box 510; the filter box 510 forms a temporary storage space for the coolant. One end of the drain pipe 530 is connected to the inner tube 110, and the other end is connected to the filter box 510. The drain pipe 530 is located downstream of the inner tube 110; the filter cartridge 540 is disposed within the filter box 510 and is used to filter the coolant in the inner tube 110. The coolant discharged from the drain pipe 530 is filtered by the filter cartridge 540. The surface of the filter cartridge 540 is arranged with filter holes. After the coolant passes through the filter cartridge 540, solid impurities are intercepted, completing the filtration of the coolant and ensuring the long-term and stable operation of the cooling system.

[0095] See Figure 5and Figure 6 As shown, in order to improve the filtering effect, the filter assembly 50 further includes: a rotating shaft 550 , a sealing plate 560 , a pressing plate 570 and a second elastic member 580 .

[0096] One end of the rotating shaft 550 is inserted into the filter box 510, and the other end extends outside the filter box 510. A plurality of filter cartridges 540 are provided, and the plurality of filter cartridges 540 are arranged at intervals on the side wall surface of the rotating shaft 550; during the rotation of the rotating shaft 550, the filter cartridges 540 also rotate therewith, so that the plurality of filter cartridges 540 can filter the coolant in turn.

[0097] A sealing plate 560 is rotatably mounted at the inlet of the drain pipe 530. A pressure plate 570 is mounted corresponding to the sealing plate 560. The filter box 510 is provided with a sliding groove 501 corresponding to the pressure plate 570, and the pressure plate 570 slides along the sliding groove 501. A second elastic member 580 is mounted in the sliding groove 501. At least one outer side surface of the filter cartridge 540 rotates to abut the pressure plate 570, causing the pressure plate 570 to press against the sealing plate 560.

[0098] As the filter cartridges 540 rotate along the rotating shaft 550, the outer side surface of one of the filter cartridges 540 rotates and abuts against the pressure plate 570. Under the pressure, the pressure plate 570 moves along the chute 501 toward the sealing plate 560. The sealing plate 560 rotates open under the pressure of the pressure plate 570, and the channel of the drain pipe 530 is opened, allowing the coolant to flow out through the drain pipe 530. At this time, the second elastic member 580, which can be a spring, is deformed.

[0099] Because the filter cartridges 540 are spaced a certain distance apart, when the position between two adjacent filter cartridges 540 rotates to the position of the pressure plate 570, the filter cartridges 540 cannot act on the pressure plate 570. Under the restoring force of the second elastic member 580, the pressure plate 570 moves along the chute 501 away from the sealing plate 560. The sealing plate 560 is no longer subject to force and automatically closes, blocking the coolant from flowing out of the drain pipe 530.

[0100] As can be seen from the above, when the filter cartridge 540 approaches the pressure plate 570, the sealing plate 560 opens, and when the filter cartridge 540 moves away, the sealing plate 560 closes. The intermittent opening of the sealing plate 560 temporarily seals the coolant in the filter box 510, increasing the filtration time of the filter cartridge 540 and the coolant, thereby improving the filtration effect.

[0101] See Figure 7As shown, to further save energy, the heat dissipation device 1 includes a pneumatic assembly 60. The pneumatic assembly 60 can use the airflow in the airflow channel 101 to drive the rotating shaft 550 to rotate. The pneumatic assembly 60 includes: a bellows 610 and a fan blade 620. The airflow in the airflow channel 101 blows the fan blade 620, which drives the rotating shaft 550 to rotate.

[0102] Specifically, the air box 610 is arranged near the filter box 510, and the rotating shaft 550 extends into the air box 610 at one end away from the filter box 510, and the air box 610 is connected to the air flow channel 101; the fan blades 620 are arranged in the air box 610, and a plurality of fan blades 620 are provided. The plurality of fan blades 620 are spaced apart on the outer wall of the rotating shaft 550, and the fan blades 620 are arranged facing the air flow channel 101. The airflow in the air flow channel 101 blows the fan blades 620 to rotate the rotating shaft 550. For example, the air outlet pipe 30 is arranged corresponding to the fan blades 620, and the airflow flowing out of the air flow channel 101 impacts the fan blades 620. The fan blades 620 are subjected to the blowing force of the air flow and transfer the blowing force to the rotating shaft 550, thereby driving the rotating shaft 550 to rotate. In order to transfer more of the impact force of the air flow into the rotational force of the rotating shaft 550, multiple fan blades 620 can be provided, so that more of the impact force from the air flow can be absorbed.

[0103] The present application also provides a vehicle comprising a frame, a booster fan, and a heat sink 1. The frame forms a support space, and the heat sink 1 is disposed within the support space. The frame protects the heat sink 1 from damage. To further accelerate the flow of natural air, a booster fan 440 is positioned near the inlet of the natural air duct 430. The rotation of the booster fan 440 stirs the surrounding air, redirecting the airflow toward the natural air intake duct. The rotation of the booster fan 440 creates a natural airflow toward the natural air intake duct.

[0104] The heat dissipation device 1 comprises a heat dissipation pipe 10, an air inlet pipe 20 and an air outlet pipe 30. The air inlet pipe 20 and the air outlet pipe 30 are both connected to the heat dissipation pipe 10 to take away the heat of the heat dissipation pipe 10.

[0105] Among them, the heat dissipation pipe 10 includes an inner tube 110 and an outer tube 120. The outer tube 120 is sleeved on the inner tube 110. The inner tube 110 is used for the circulation of coolant. An air flow channel 101 is formed between the inner wall surface of the outer tube 120 and the outer wall surface of the inner tube 110. There is a gap between the inner tube 110 and the outer tube 120, and this gap refers to the air flow channel 101. The inlet and outlet of the inner tube 110 are respectively connected to the heat dissipation object, and the heat dissipation object here mainly refers to the engine 2 or the battery stack. The outer tube 120 is partially sleeved on the outer wall surface of the inner tube 110. In order to make the sleeve area of ​​the outer tube 120 and the inner tube 110 larger, the outer tube 120 can be sleeved at the inlet of the inner tube 110 and extend along the outer wall surface of the inner tube 110 to the outlet position of the inner tube 110.

[0106] The air inlet duct 20 is connected to the outer tube 120, and the lumen of the air inlet duct 20 is in communication with the air flow channel 101. The air outlet duct 30 is connected to the outer tube 120, and the lumen of the air outlet duct 30 is in communication with the air flow channel 101. The air inlet duct 20 is used to introduce cooling air, which flows along the air flow channel 101 and is discharged from the air outlet duct 30. The coolant releases heat absorbed from the engine 2 or the fuel cell stack to the inner tube 110. As the cooling air flows in the air flow channel 101, heat exchange occurs between the cooling air and the inner tube 110, transferring heat from the inner tube 110 to the cooling air. As a result, the heat of the coolant is exchanged with the cooling air, which then flows in the air flow channel 101 and carries away the exchanged heat.

[0107] In the vehicle of this embodiment, the inner tube 110 of the heat dissipation pipe 10 is used to circulate the coolant. After completing the heat exchange with the cooling object, the coolant flows to the heat dissipation pipe 10, and the heat is dissipated at the heat dissipation pipe 10. An air flow channel 101 is formed between the outer tube 120 and the inner tube 110. The cooling air enters the air flow channel 101 from the air inlet pipe 20, and takes away the heat emitted from the surface of the inner tube 110. The cooling air is discharged from the air outlet pipe 30 after circulating in the air flow channel 101. It can be seen from this that the present technical solution achieves heat dissipation more effectively by accelerating the air flow on the outer wall of the inner tube 110, thereby ensuring the normal use of the engine 2 or the battery stack.
