Description

Technical Field

[0001] This invention relates to the field of ultrasonic technology, and in particular to an ultrasonic cannon device. Background Technology

[0002] With the widespread application of ultrasound therapy technology in fields such as medical aesthetics and physical rehabilitation, the ultrasonic beam device, as a core treatment equipment, directly affects the treatment effect and safety due to its operational stability and temperature control performance. Current technologies suffer from problems such as the inability to effectively control the temperature of the treatment area using the ultrasonic beam propagation method, leading to a high risk of skin burns and unsatisfactory treatment results.

[0003] To address the aforementioned temperature rise issue, some devices incorporate thermoelectric coolers (TECs) for active cooling, connecting the cold end to the ultrasonic propagation unit to reduce its operating temperature. However, during the cooling process, the TEC generates an equal amount or even more waste heat at the hot end. If heat dissipation at the hot end is inadequate, the temperature at the hot end will continue to rise, which in turn inhibits the cooling capacity of the cold end, creating a vicious cycle of "cooling failure."

[0004] Currently, although most devices are equipped with heat dissipation components consisting of fans and radiators, the airflow path of the fans and the geometric layout of the radiators do not form an effective coordination. The airflow is prone to disordered diffusion, short circuits, and bypasses, resulting in insufficient heat dissipation in local areas and low overall air cooling efficiency, making it difficult to meet the stable temperature control requirements of ultrasonic cannon devices for long-term continuous operation. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing an ultrasonic cannon device. Through structural optimization, it can achieve a directional airflow path, thereby realizing efficient forced air cooling of the hot end of the cooling element and significantly reducing the temperature rise of the hot end.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: an ultrasonic cannon device, including a shell, a heat conductor, a cooling plate, a heat dissipation assembly, and an ultrasonic propagation unit disposed in the shell; the cold end of the cooling plate cooperates with the ultrasonic propagation unit through the heat conductor; the heat dissipation assembly includes a radiator and a fan disposed in the shell, the radiator being fitted to the hot end of the cooling plate; an air supply channel is provided in the shell, and the radiator is disposed in the air supply channel; the air outlet of the fan is connected to the inlet of the air supply channel, the shell has an air outlet at the outlet of the air supply channel, and an air inlet at the air inlet side of the fan.

[0007] In a preferred embodiment, the radiator includes a heat dissipation block, which is attached to the hot end of the cooling fin. The side of the heat dissipation block facing away from the cooling fin has a plurality of heat dissipation fins arranged in parallel along a preset direction, and a heat dissipation gap is formed between adjacent heat dissipation fins. The air supply direction of the air supply channel is perpendicular to the arrangement direction of the plurality of heat dissipation fins and the extension direction of the heat dissipation fins, so that the airflow can pass through the heat dissipation gap when flowing through the radiator.

[0008] In a preferred embodiment, the device further includes a fan shroud, which is disposed inside the housing and covers the outside of the radiator, and the fan shroud and the housing enclose the air supply channel to form the air supply channel; the fan shroud is through at both ends of the air supply channel in the air supply direction.

[0009] In a preferred embodiment, the housing includes an outer shell and a cover. The outer shell has a first opening and a second opening at opposite ends. The fan hood and fan are disposed inside the outer shell and are arranged sequentially and connected along the air delivery direction of the air delivery channel. The fan hood and the outer shell form the air delivery channel. The ultrasonic propagation unit is connected to the first opening of the outer shell, and the cover is connected to the second opening. The air outlet and air inlet are respectively disposed on the outer shell.

[0010] In a preferred embodiment, a first thermally conductive interface material is provided between the heat sink and the hot end of the cooling chip.

[0011] In a preferred embodiment, the heat conductor includes a heat-conducting block and a second heat-conducting interface material. The heat-conducting block is attached to the cold end of the cooling chip through the second heat-conducting interface material, and the heat-conducting block partially extends into the liquid medium in the ultrasonic propagation unit.

[0012] In a preferred embodiment, the heat-conducting block has a plurality of parallel heat-conducting fins or heat-conducting pillars on the side facing away from the cooling chip, and the heat-conducting fins or heat-conducting pillars extend into the liquid medium.

[0013] In a preferred embodiment, the ultrasonic propagation unit includes a liquid storage tank, a sealing membrane, a liquid medium filled in the liquid storage tank, and an ultrasonic transducer disposed in the liquid storage tank; the liquid storage tank has a third opening and a fourth opening at opposite ends, the heat-conducting block is sealed to the third opening of the liquid storage tank, and the sealing membrane is attached to the fourth opening of the liquid storage tank.

[0014] In a preferred embodiment, there are multiple air inlets, which are arranged radially; there are also multiple air outlets, which are arranged radially.

[0015] In a preferred embodiment, a control component is also included, which is disposed within the housing, for controlling the operating status of the ultrasonic propagation unit, the cooling chip, and the fan.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention constructs a directional, restricted airflow structure by setting an air supply channel within the housing and placing the radiator within this channel, connecting the fan outlet to the air supply channel inlet. The housing has an outlet at the air supply channel outlet and an inlet on the fan inlet side. This ensures that airflow can only flow along a predetermined path from the inlet to the outlet via the radiator. This air supply channel effectively avoids the problems of disordered airflow diffusion, short-circuiting, or bypassing in traditional heat dissipation structures, ensuring that all airflow output from the fan is forced to flow across the radiator surface, significantly improving heat exchange efficiency.

[0018] 2. The side of the heat sink facing away from the cooling fins has heat dissipation fins arranged parallel to each other in a predetermined direction. Adjacent heat dissipation fins form heat dissipation gaps. The airflow direction of the air supply channel is perpendicular to the arrangement direction and extension direction of the multiple heat dissipation fins. This structural design significantly increases the heat dissipation area of ​​the radiator by utilizing multiple heat dissipation fins, effectively reduces airflow resistance when air passes through the radiator, improves air cooling efficiency, and enhances the overall heat exchange uniformity of the radiator.

[0019] 3. The present invention also includes a fan shroud, which is disposed inside the housing and covers the outside of the radiator, and the fan shroud and the housing enclose the air supply channel. This fan shroud not only simplifies the forming structure of the air supply channel, but also, through its coordinated enclosure with the housing, confines the airflow within a preset path, effectively preventing bypassing, leakage, or turbulence of the airflow around the radiator, ensuring that all airflow output by the fan is forced to flow across the radiator surface, significantly improving air-cooling efficiency and thermal management stability.

[0020] 4. A first thermally conductive interface material is provided between the hot end of the heat sink and the cooling element. The introduction of this first thermally conductive interface material effectively fills the air gap between the microscopic surfaces of the two, significantly reduces the contact thermal resistance, and enables the heat generated by the cooling element during operation to be quickly and evenly conducted to the heat sink, avoiding the formation of local hot spots, improving the heat dissipation efficiency of the hot end, thereby ensuring that the cold end of the cooling element continuously and stably transfers cold energy to the ultrasonic propagation unit, extending the continuous working time of the equipment and improving the temperature control accuracy.

[0021] 5. The heat-conducting block is bonded to the cold end of the cooling chip through a second thermal interface material. This structure achieves a low thermal resistance connection between the cold end of the cooling chip and the heat-conducting block through the second thermal interface material, overcoming the problem of uneven heat transfer caused by surface roughness in traditional direct bonding.

[0022] 6. The side of the heat-conducting block facing away from the cooling element has multiple parallel heat-conducting fins or pillars that extend into the liquid medium. This structure greatly increases the solid-liquid heat exchange contact area, allowing heat to diffuse rapidly in the liquid and preventing localized overheating. Simultaneously, the parallel arrangement of the heat-conducting fins or pillars guides the liquid to form stable convection, enhancing the convective heat transfer coefficient and achieving uniform, efficient, and continuous cooling of the ultrasound propagation unit. This significantly improves temperature control accuracy and user comfort during treatment, providing reliable protection for long-duration, high-power ultrasound treatment.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] Furthermore, in the description of this invention, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0033] Please see Figures 1-6 As shown, an ultrasonic cannon device of the present invention includes a housing 1, a heat conductor, a cooling element 3, a heat dissipation assembly, and an ultrasonic propagation unit 2 disposed within the housing 1. The cold end of the cooling element 3 cooperates with the ultrasonic propagation unit 2 through the heat conductor to achieve active cooling of the ultrasonic propagation unit 2. The heat dissipation assembly includes a radiator 4 and a fan 5 disposed within the housing 1. The radiator 4 is attached to the hot end of the cooling element 3 to promptly dissipate waste heat generated during the cooling process. An air supply channel 61 is provided inside the housing 1, and the radiator 4 is disposed within the air supply channel 61. The air outlet of the fan 5 is directly connected to the inlet of the air supply channel 61. An air outlet 112 is provided at the outlet of the air supply channel 61, and an air inlet 111 is provided on the air inlet side of the fan 5, thereby forming a complete, directional, forced air-cooling circulation path from the air inlet 111 → fan 5 → air supply channel 61 → radiator 4 → air outlet 112.

[0034] In this embodiment, the radiator 4 includes a heat sink 41, which is attached to the hot end of the cooling fin 3. The side of the heat sink 41 facing away from the cooling fin 3 has multiple heat sink fins 42 arranged parallel to each other in a preset direction, with heat dissipation gaps formed between adjacent fins 42. The heat sink 41 is specifically made of metal, preferably aluminum alloy, and the multiple heat sink fins 42 are integrally formed with the heat sink 41. The airflow direction of the air supply channel 61 is perpendicular to the arrangement direction of the multiple heat sink fins 42 and the extension direction of the heat sink fins 42. This allows the airflow to smoothly pass through the heat dissipation gaps between the heat sink fins 42 after entering the air supply channel 61, effectively reducing airflow resistance, preventing eddies or local pressure drops, and ensuring full contact with the surface of the heat sink fins 42, significantly improving heat exchange efficiency.

[0035] In this embodiment, as Figure 1 As shown, the length direction of the housing 1 is defined as the X-axis, the width direction as the Y-axis, and the height direction as the Z-axis. Multiple heat dissipation fins 42 are arranged parallel to each other along the Y-axis, and their extension direction is set along the Z-axis; the air supply channel 61 extends along the X-axis. Thus, the air supply direction (X-axis) is perpendicular to the arrangement direction (Y-axis) and extension direction (Z-axis) of the heat dissipation fins 42, forming a three-dimensional orthogonal structure. This allows the airflow to sweep laterally across the surface of the heat dissipation fins 42 as it flows through the heat dissipation gap, achieving efficient convective heat transfer.

[0036] Furthermore, the present invention also includes a fan shroud 6, which is disposed inside the housing 1 and covers the outside of the radiator 4, and the fan shroud 6 and the housing 1 enclose an air supply channel 61; the two ends of the fan shroud 6 are through-flow in the air supply direction of the air supply channel 61. The arrangement of the fan shroud 6 confines the airflow within the sealed channel formed by the fan shroud 6 and the inner wall of the housing 1, effectively preventing the airflow from bypassing, leaking or diffusing around the radiator 4, ensuring that all the airflow output by the fan 5 is forced to flow through the heat dissipation fins 42, and greatly improving the air cooling efficiency. At the same time, the through-flow structure at both ends of the fan shroud 6 not only ensures the continuous flow of airflow, but also simplifies the assembly process, achieving good airtightness without the need for additional sealing structures.

[0037] like Figure 1As shown, the housing 1 specifically includes an outer shell 11 and a cover 12, with a first opening and a second opening at opposite ends. A fan shroud 6 and a fan 5 are disposed inside the outer shell 11 and are arranged sequentially and connected along the airflow direction of the airflow channel 61. The fan shroud 6 and the outer shell 11 enclose the airflow channel 61. Specifically, the outer shell 11 is generally elongated, with a first opening at one end along its length and a second opening at its top. This second opening is open, allowing the fan 5, fan shroud 6, etc., to be placed inside the outer shell 11. The ultrasonic propagation unit 2 is connected to the first opening of the outer shell 11, and the cover 12 is connected to the second opening and can be detachable. An air outlet 112 and an air inlet 111 are respectively disposed on the outer shell 11. Specifically, the air outlet 112 is located on the side of the outer shell 11 along its length near the airflow channel 61, and the air inlet 111 is approximately located in the middle region of the bottom of the outer shell 11. The modular design allows the internal components to be arranged linearly, facilitating overall assembly and maintenance.

[0038] like Figure 4 As shown, there are multiple air inlets 111 arranged radially; there are also multiple air outlets 112 arranged radially. This distribution allows external air to enter evenly from multiple locations around the bottom of the casing 11, avoiding uneven heat dissipation caused by insufficient local air intake or concentrated airflow. The air outlets 112 are also arranged radially, allowing hot air to be evenly discharged at the outlet of the air supply channel 61, reducing exhaust noise, improving user comfort, and enhancing the overall stability of thermal management.

[0039] In a preferred embodiment, a first thermally conductive interface material 7 is provided between the heat sink 4 and the hot end of the cooling element 3. This first thermally conductive interface material 7 fills the microscopic gap between the heat sink 4 and the hot end of the cooling element 3, effectively eliminating the thermal resistance caused by the air layer, achieving a low thermal resistance and high thermal conductivity connection between the two, ensuring that the heat generated by the cooling element 3 during operation can be quickly and evenly transferred to the heat sink 4, avoiding local overheating that leads to a decrease in cooling efficiency, and ensuring the long-term stable operation of the cooling element 3.

[0040] In a preferred embodiment, the heat conductor includes a heat-conducting block 8 and a second heat-conducting interface material 9. The heat-conducting block 8 is attached to the cold end of the cooling chip 3 via the second heat-conducting interface material 9, and the heat-conducting block 8 partially extends into the liquid medium in the ultrasonic propagation unit 2. The first heat-conducting interface material 7 and the second heat-conducting interface material 9 can be implemented using one or more combinations of thermally conductive silicone grease, thermally conductive pads, phase change materials, or thermally conductive adhesives. This structure achieves efficient thermal coupling between the cold end of the cooling chip 3 and the heat-conducting block 8 through the second heat-conducting interface material 9, stably transferring cold energy from the cooling chip 3 to the heat-conducting block 8. The heat-conducting block 8 extends into the liquid medium, allowing the cold energy to be directly transferred to the liquid medium of the ultrasonic propagation unit 2, realizing direct solid-liquid heat exchange, significantly shortening the cold energy transfer path, improving the temperature response speed, and avoiding the temperature control delay caused by the lag in thermal conduction of the shell 1 in traditional indirect cooling methods.

[0041] like Figure 5 As shown, the ultrasound propagation unit 2 includes a liquid reservoir 21, a sealing membrane 24, a liquid medium 22 filled in the liquid reservoir 21, and an ultrasound transducer 23 disposed in the liquid reservoir 21. The liquid reservoir 21 has a third opening and a fourth opening at opposite ends. A heat-conducting block 8 is sealed to the third opening of the liquid reservoir 21, and the sealing membrane 24 is affixed to the fourth opening of the liquid reservoir 21. In this structure, the sealed connection between the heat-conducting block 8 and the liquid reservoir 21 ensures that the liquid medium 22 does not leak, while simultaneously achieving physical connectivity for heat conduction. The sealing membrane 24 serves as the sound-transmitting interface for ultrasound, efficiently transmitting ultrasound energy, reducing reflection loss, and improving treatment efficiency.

[0042] Furthermore, the side of the heat-conducting block 8 facing away from the cooling plate 3 is provided with multiple parallel heat-conducting columns 81, which extend into the liquid medium 22. In other embodiments, heat-conducting fins can be used instead of heat-conducting columns 81, which is an equivalent replacement. This structure significantly increases the heat exchange contact area between the heat-conducting block 8 and the liquid medium 22, allowing the cooling energy to diffuse rapidly in the liquid, forming a uniform cooling field and effectively preventing local temperature rise. At the same time, the parallel arrangement of the fins or heat-conducting columns 81 guides the liquid to form stable convection during flow, enhancing the convective heat transfer coefficient and achieving continuous, uniform, and efficient cooling of the ultrasonic propagation unit 2. This ensures that the ultrasonic transducer can maintain a constant operating temperature under high-power continuous operation, avoiding sound field distortion or energy attenuation caused by thermal drift. The heat-conducting block 8 is made of metal, preferably aluminum alloy, and it is integrally formed with the heat-conducting fins or heat-conducting columns 81.

[0043] The present invention also includes a control component 10, which is disposed within the housing 1 and is used to control the operating status of the ultrasonic propagation unit 2, the cooling chip 3, and the fan 5. Specifically, the control component 10 is disposed above the fan cover 6 and the fan 5 and is covered by the cover 12.

[0044] The working principle of the ultrasonic cannon device of the present invention is as follows:

[0045] When the device is working, the ultrasonic transducer 23 generates ultrasonic vibrations when energized, and transmits energy to the treatment area through the liquid medium 22. During this process, the ultrasonic transducer 23 generates a large amount of heat due to insufficient electroacoustic conversion efficiency. If heat is not dissipated in time, the temperature will rise. To achieve stable temperature control, the semiconductor cooling chip 3 starts working: its cold end is tightly attached to the heat-conducting block 8 through the second thermal interface material 9, and the heat-conducting block 8 extends further into the liquid medium 22 inside the ultrasonic propagation unit 2, quickly dissipating heat from the ultrasonic propagation unit 2 to achieve direct cooling of the treatment area; at the same time, the waste heat generated by the hot end of the cooling chip 3 is transferred to the heat sink 4 through the first thermal interface material 7. After the fan 5 starts, external air is drawn in through the air inlet 111 on the bottom surface of the outer casing 11, flows directionally along the air supply channel 61, sweeps horizontally across the surface of each heat dissipation fin 42, carries away the heat from the hot end, and is discharged through the air outlet 112 on the side wall of the outer casing 11, forming a highly efficient, low-resistance forced air cooling cycle. Figure 3 , Figure 6 As shown in the figure, the arrows indicate the direction of airflow.

[0046] This invention integrates a directional forced air cooling structure, a dual-stage thermal interface thermal management system, and intelligent control of the control component 10, achieving efficient, stable, and precise temperature control of the ultrasonic propagation unit 2. Specifically, the invention employs a directional airflow channel 61 formed by the fan shroud 6 and the housing 1, significantly improving heat exchange efficiency; the application of the first thermal interface material 7 and the second thermal interface material 9 optimizes the thermal resistance matching between the hot and cold ends; and the intelligent control component 10 enables closed-loop temperature regulation, ensuring precise temperature control of the ultrasonic propagation unit 2. This invention overcomes the bottlenecks of low heat dissipation efficiency, delayed temperature control, and easy overheating in traditional ultrasonic equipment, combining high heat dissipation performance, high structural integration, and high maintenance convenience, making it particularly suitable for continuous treatment scenarios with stringent safety and stability requirements, such as medical aesthetics and physical rehabilitation.
