It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

Therefore, it should not be understood as a limitation on the present invention.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate relative importance or the number of technical features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined. The following is a more detailed description of the specific implementation of this utility model in conjunction with specific embodiments:

[0042] like Figures 1 to 3As shown, a heat dissipation device provided by an embodiment of the present invention can be applied to electronic devices with small heat dissipation spaces, such as photographic equipment (such as fill lights), laptop computers, or tablet computers. In order to improve portability, the above-mentioned electronic devices are usually compressed in size, so the space for arranging the heat dissipation device becomes very small. However, the above-mentioned electronic devices generate a large amount of heat when working, and require a heat dissipation device with high heat dissipation efficiency to dissipate heat. Existing electronic devices use traditional heat dissipation fans for heat dissipation, and traditional heat dissipation fans require blades to rotate to generate wind pressure, which makes the heat dissipation fan bulky and difficult to be arranged in electronic devices with small heat dissipation spaces. The heat dissipation device provided by this embodiment is small in size and can be arranged in a small heat dissipation space, taking into account both the portability and heat dissipation performance of the electronic device. The following is an explanation through specific embodiments:

[0043] The heat dissipation device of this embodiment includes:

[0044] The blast pipe 1 is provided with a blast channel 11 and an air inlet 12 and an air outlet 13 connected to the blast channel 11;

[0045] A first one-way valve 2 is provided in the air inlet hole 12 and is used to limit the one-way intake of gas from the outside of the air inlet hole 12 into the blast channel 11;

[0046] A second one-way valve 3 is provided in the air outlet 13 and is used to limit the gas from the blast channel 11 to be discharged out of the air outlet 13 in one direction;

[0047] The driving structure 4 is disposed in the blast channel 11 . The driving structure 4 can drive the gas to be sucked into the blast channel 11 from outside the air inlet hole 12 and then discharged from the blast channel 11 to outside the air outlet hole 13 .

[0048] Here, it can be understood that the blast pipe 1 refers to a tubular structure for forming the blast channel 11; the blast channel 11, an air inlet 12, and an air outlet 13 are provided inside the blast pipe 1; the blast channel 11 refers to a channel for gas to enter or exhaust; the air inlet 12 refers to an opening for gas to enter the blast channel 11 from outside the blast channel 11, and the air inlet 12 is provided throughout the blast pipe 1 and is connected to the blast pipe 1; the air outlet 13 refers to an opening for gas to exit the blast channel 11 from outside the blast channel 11, and is connected to the blast pipe 1;

[0049] The first one-way valve 2 is a valve body used to restrict the unidirectional flow of gas, that is, to prevent the reverse flow of gas. In this embodiment, the first one-way valve 2 is disposed in the air inlet hole 12. The first one-way valve 2 is used to restrict the unidirectional inhalation of gas from outside the air inlet hole 12 into the blast passage 11. That is, gas can only enter the blast passage 11 from outside the blast passage 11 through the air inlet hole 12, but cannot be discharged from the blast passage 11 through the air inlet hole 12 to the outside of the blast passage 11.

[0050] The second one-way valve 3 is a valve body used to restrict the flow of gas in one direction, that is, to prevent the reverse flow of gas. In this embodiment, the second one-way valve 3 is disposed in the air outlet 13. The second one-way valve 3 is used to restrict the gas from being discharged from the blast channel 11 through the air outlet 13 to the outside of the blast channel 11. That is, the gas can only be discharged from the blast channel 11 through the air outlet 13 to the outside of the blast channel 11, but cannot enter the blast channel 11 from the outside through the air inlet 12.

[0051] The driving structure 4 refers to a structure used to drive the flow of gas inside and outside the blast channel 11; the driving structure 4 includes but is not limited to a piston 44 structure or a vibration structure. The driving structure 4 can adjust the volume of the blast channel 11 by moving the piston 44 to change the pressure inside the blast channel 11 to drive the gas to flow. The vibration structure can also adjust the volume inside the blast channel 11 by vibration to change the pressure inside the blast channel 11 to drive the gas to flow; the driving structure 4 is arranged in the blast channel 11, and the driving structure 4 is used to drive the gas outside the blast channel 11 into the blast channel 11 through the air inlet 12, and then drive the gas in the blast channel 11 to be discharged from the blast channel 11 through the air outlet 13, and arrange the heat-generating components outside the air outlet 13 to achieve air cooling and heat dissipation.

[0052] The working principle of the heat dissipation device provided in this embodiment is as follows:

[0053] The heating component is arranged at the air outlet 13, and the driving structure 4 is controlled to form a negative pressure in the blast channel 11, so that the gas enters the blast channel 11 from outside the blast channel 11 through the first one-way valve 2 of the air inlet 12, and then the driving structure 4 is controlled to form a positive pressure in the blast channel 11, so that the gas is discharged from the blast channel 11 through the second one-way valve 3 of the air outlet 13 to the outside of the blast channel 11. Since the heating component is arranged corresponding to the air outlet 13, air cooling and heat dissipation of the heating component are achieved.

[0054] By adopting the above technical solution, the use of traditional cooling fans for heat dissipation is avoided. The heat dissipation device provided in this embodiment is small in size and can be arranged in a small heat dissipation space, taking into account the portability and heat dissipation performance of the electronic device.

[0055] In one embodiment, the driving structure 4 includes a piston 44 and a power rod 45 for driving the piston 44 to move back and forth. The piston 44 is arranged in the blast channel 11. The piston 44 is located on the side of the air inlet hole 12 away from the air outlet hole 13. The power rod 45 is used to drive the piston 44 to move in a direction close to or away from the air inlet hole 12; when the piston 44 moves in a direction away from the air inlet hole 12, the gas outside the air inlet hole 12 enters the blast channel 11; when the piston 44 moves in a direction close to the air inlet hole 12, the gas in the blast channel 11 is discharged out of the air outlet hole 13.

[0056] Here, it can be understood that the driving structure 4 includes a piston 44 and a power rod 45, wherein the inner wall of the blast pipe 1, the first one-way valve 2 and the second one-way valve 3 are enclosed to form a blast channel 11, and the piston 44 is arranged in the blast channel 11. The piston 44 can move in the blast channel 11, and the piston 44 is located on the side of the air inlet 12 away from the air outlet 13. In this way, when the power rod 45 drives the piston 44 to move in the direction away from the air inlet 12, the volume of the blast channel 11 becomes larger, and a negative pressure is formed in the blast channel 11 to drive the gas outside the blast channel 11 into the blast channel 11 from the first one-way valve 2 of the air inlet 12; and when the power rod 45 drives the piston 44 to move in the direction close to the air inlet 12, the volume of the blast channel 11 becomes smaller, and a positive pressure is formed in the blast channel 11 to drive the gas in the blast channel 11 to be discharged from the second one-way valve 3 of the air outlet 13, so that the gas is blown to the heat-generating components to achieve air cooling and heat dissipation.

[0057] By adopting the above technical solution, the technology of the piston 44 is mature, and the reliability of the operation of the heat dissipation device is improved.

[0058] like Figure 4 As shown, in one embodiment, the driving structure 4 includes a vibration membrane 41 and an electromagnet 42. The vibration membrane 41 is magnetic and is arranged in the blast channel 11. The vibration membrane 41 is located on the side of the air inlet 12 away from the air outlet 13. The electromagnet 42 can generate a magnetic field to drive the vibration membrane 41 to vibrate in a direction close to or away from the air inlet 12; when the vibration membrane 41 vibrates in a direction away from the air inlet 12, the gas outside the air inlet 12 enters the blast channel 11; when the vibration membrane 41 vibrates in a direction close to the air inlet 12, the gas in the blast channel 11 is discharged out of the air outlet 13.

[0059] Here, it can be understood that the vibration membrane 41 refers to a membrane that has both elasticity and magnetism. A permanent magnet 43 is provided on the vibration membrane 41, and the vibration membrane 41 can vibrate back and forth under the magnetic force of the magnetic field; when the electromagnet 42 generates a positive magnetic field, the magnetic force of the magnetic field drives the vibration membrane 41 to vibrate in a direction away from the air inlet 12, so that the volume of the blast channel 11 becomes larger, and a negative pressure is formed in the blast channel 11 to drive the gas outside the blast channel 11 into the blast channel 11 from the first one-way valve 2 of the air inlet 12; and when the electromagnet 42 generates a reverse magnetic field, the magnetic force of the magnetic field drives the vibration membrane 41 to vibrate in a direction close to the air inlet 12, so that the volume of the blast channel 11 becomes smaller, and a positive pressure is formed in the blast channel 11 to drive the gas in the blast channel 11 to be discharged from the second one-way valve 3 of the air outlet 13, so that the gas is blown to the heat-generating components to achieve air cooling and heat dissipation.

[0060] By adopting the above technical solution, the volume of the vibration membrane 41 and the electromagnet 42 is smaller, which can further reduce the space occupied by the heat dissipation device.

[0061] In one embodiment, the blast pipe 1 is in the shape of a circular tube, the air outlet 13 is provided at the bottom or top of the blast pipe 1 , and the air inlet 12 is located on the circumferential surface of the blast pipe 1 .

[0062] By adopting the above technical solution, the air outlet 13 is located at the bottom or top of the blast pipe 1, which is conducive to the arrangement of the air outlet 13 when multiple blast pipes 1 are arranged; and the circular tubular blast pipe 1 allows two blast pipes 1 to still have an air inlet gap when they are arranged adjacent to each other; the air inlet hole 12 is located on the circumferential surface of the blast pipe 1, which is conducive to the connection between the air inlet hole 12 and the air inlet gap, and is also conducive to the arrangement of the air inlet hole 12.

[0063] In one embodiment, a plurality of air inlet holes 12 are provided on the circumferential surface of the blast pipe 1 , and the plurality of air inlet holes 12 are sequentially arranged along the circumference of the blast pipe 1 .

[0064] Here, it can be understood that since the air inlet gap of each blast tube 1 is formed along the circumferential direction, multiple air inlet holes 12 are arranged on the circumferential surface of the blast tube 1, so that each air inlet hole 12 can be connected to the air inlet gap, and at the same time it is beneficial for the blast channel 11 to take in air from multiple air inlet holes 12, thereby improving the blast efficiency.

[0065] By adopting the above technical solution, the suction efficiency of the gas in the blast channel 11 is improved.

[0066] like Figure 5 As shown, in one embodiment, the heat dissipation device includes a plurality of blast tubes 1 and a fixing plate 5 for fixing the blast tubes 1 . The plurality of blast tubes 1 are arranged in an array on the fixing plate 5 , and a first air inlet gap 14 is formed between two adjacent blast tubes 1 .

[0067] It is understood that the array of multiple blast tubes 1 on the fixed plate 5 improves the regularity of the arrangement of the blast tubes 1 and the heat dissipation efficiency of the heat dissipation device. A first air inlet gap 14 is formed between two adjacent blast tubes 1. The first air inlet gap 14 communicates with the outside air, allowing air to enter the air inlet hole 12 through the first air inlet gap 14 and then enter the blast channel 11. It should be further explained that each blast tube 1 is correspondingly provided with a first one-way valve 2, a second one-way valve 3, and a drive mechanism 4.

[0068] By adopting the above technical solution, the heat dissipation efficiency of the heat dissipation device is improved.

[0069] In one embodiment, the fixing plate 5 is provided with a heat dissipation surface 50 facing the heat-generating component, and a plurality of air outlet holes 13 are located on the heat dissipation surface 50 .

[0070] Here, it can be understood that the heat dissipation surface 50 is used to face the heat-generating components, and a plurality of air outlet holes 13 are arranged on the heat dissipation surface 50, which is conducive to concentrating the gas discharged from the blast channel 11 and improving the heat dissipation efficiency.

[0071] By adopting the above technical solution, the heat dissipation efficiency is improved.

[0072] In one embodiment, the fixing plate 5 includes at least two fixing plate units 51 arranged in parallel and spaced apart. A second air inlet gap 14 is formed between the two fixing plate units 51 . The two fixing plate units 51 jointly fix the plurality of blast pipes 1 .

[0073] Here, it can be understood that a second air inlet gap is formed between the two fixed plate units 51. Since the two fixed plate units 51 are arranged in parallel and spaced apart, the second air inlet gap extends parallel to the plate surface of the fixed plate unit 51, so that the heat dissipation device can be thinned.

[0074] By adopting the above technical solution, the thinness of the heat dissipation device is improved.

[0075] In one embodiment, the heat dissipation device further includes a control structure for controlling the driving structure 4 , and the control structure is electrically connected to the plurality of driving structures 4 .

[0076] Here, it can be understood that the control structure refers to a structure used to control the drive structure 4. The control structure includes but is not limited to control components such as control chips. The control structure can control multiple drive structures 4 separately, so that the multiple drive structures 4 run synchronously or separately, thereby controlling the heat dissipation efficiency of the heat dissipation device.

[0077] By adopting the above technical solution, the control flexibility of the heat dissipation device is improved.

[0078] In a second aspect, an electronic device is provided, comprising a heat-generating component and the above-mentioned heat dissipation device, wherein the heat dissipation device is used to dissipate heat from the heat-generating component.

[0079] By adopting the above technical solution, on the basis of having the advantages of the heat dissipation device of the above embodiment, the electronic device of this embodiment also has the advantages of small size and good heat dissipation efficiency.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
