Description

Technical Field

[0001] The utility model relates to the technical field of laser hair removal devices, in particular to a high-efficiency radiator for laser hair removal devices. Background Art

[0002] In the design and manufacturing of modern electronic equipment, heat dissipation efficiency is a key factor in ensuring stable operation and extending the lifespan of the equipment. With the continuous advancement of technology, the integration of electronic products has become increasingly higher, and the power density has also increased, which places more stringent requirements on the heat dissipation system. As a common home beauty device, hair removal devices integrate multiple electronic components and light source systems, generating a large amount of heat during operation. However, due to the compact design of hair removal devices, achieving efficient heat dissipation within this limited space has become a pressing issue.

[0003] Currently, most hair removal devices on the market use a heat dissipation method that combines a radiator with a fan. The radiator is usually placed at the air inlet or outlet of the fan to use the airflow of the fan to accelerate the dissipation of heat. However, this design method faces many challenges in space-constrained products such as hair removal devices. First, due to the limited product space, the radiator area is often not large enough, resulting in limited heat dissipation efficiency, and the product is prone to high heat generation during use. Secondly, the layout and position of the radiator are also limited by the product structure, making it difficult to achieve optimal heat dissipation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a high-efficiency radiator for a laser hair removal device, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-efficiency radiator for a laser hair removal device, comprising a frame body installed inside the shell of the laser hair removal device, a fan installed inside the frame body, and a heat dissipation module installed on the upper part of the frame body, the heat dissipation module using a metal heat conducting plate as a carrier, air inlet fins connected to the upper part of the metal heat conducting plate, and air outlet fins connected to the lower part of the metal heat conducting plate, the air inlet fins are located above the air inlet of the fan, and the air outlet fins are located on the side of the air outlet of the fan.

[0006] Furthermore, a bracket is installed at the bottom end of the frame body, and a lamp tube and a reflector are installed inside the bracket respectively. The reflector is a curved structure and can reflect the light diffused backward by the lamp tube to the front.

[0007] Furthermore, sapphire and a cooling plate are installed inside the bracket, the cooling plate is in contact with the sapphire, the metal heat conducting plate is located above the cooling plate, and the metal heat conducting plate and the cooling plate are connected via a heat conducting layer.

[0008] Furthermore, an air duct insulating sheet is connected to the interior of the bracket, and the air duct insulating sheet is located on the opposite side of the reflector with the lamp tube as the center.

[0009] Furthermore, a “T”-shaped heat dissipation fixing frame is installed on the upper portion of the frame body, and the heat dissipation module is installed on the upper portion of the frame body through the heat dissipation fixing frame.

[0010] Furthermore, the air inlet of the fan is arranged at the upper part, and a through hole is reserved at the upper part of the frame body, the position of the through hole corresponds to the air inlet, and the position of the air inlet fins corresponds to the through hole.

[0011] Furthermore, heat pipes are symmetrically arranged between the metal heat conducting plate and the air inlet fins.

[0012] The utility model provides a high-efficiency heat sink for a laser hair removal device. Compared with the prior art, it has the following advantages:

[0013] The laser hair removal device's high-efficiency heat sink features an integrated heat dissipation module consisting of three main components: a metal heat pipe, a metal plate, and metal fins. At the fan's air intake, there are multiple regular or irregular metal fins connected by heat pipes. Similarly, multiple regular or irregular metal fins are arranged in the air duct at the air outlet. This maximizes the heat sink's area within the same product size, while the fan generates airflow convection to remove heat from the heat sink, achieving product cooling.

[0014] The Sapphire Hair Removal Device works by utilizing the photothermal effect. Using special lasers or intense pulsed light to illuminate the deep layers of the skin, it disrupts the growth environment of hair follicles, deactivating their vitality and achieving the desired effect. This technology allows the hair follicles to absorb the heat, causing them to shrink and close, making them unable to provide nutrients for the hair, thus achieving permanent hair removal.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 The utility model provides a technical solution: a high-efficiency radiator for laser hair removal, which consists of a frame body 1, a bracket 2, a fan 3, a heat dissipation module 4, a lamp 5, a sapphire 6, a cooling sheet 7, a heat-conducting layer 8, an air duct insulating sheet 9, a reflector 10 and a heat dissipation fixing frame 11. The frame body 1 is installed inside the shell of the laser hair removal device, the bracket 2 is installed at the bottom end of the frame body 1, the fan 3 is installed inside the frame body 1, the heat dissipation module 4 is installed on the upper part of the frame body 1 through a "T"-shaped heat dissipation fixing frame 11 and screws, the lamp 5, the sapphire 6, the cooling sheet 7, the heat-conducting layer 8, the air duct insulating sheet 9. The reflector 10 is installed inside the bracket 2. The lamp 5 is a xenon lamp (laser lamp). The cooling plate 7 is bonded to the sapphire 6 to cool the sapphire. The temperature of the hot end of the cooling plate 7 is then transferred to the heat conducting layer 8 and then to the heat dissipation module 4. The fan 3 drives the air flow, thereby removing the heat from the heat dissipation module 4. Because the metal fins of the radiator outlet extend deep into the lamp, the product design space is limited. The air duct insulation plate 9 is added to meet the creepage distance and electrical clearance distance requirements required by safety regulations. The reflector 10 has a curved structure and can reflect the light diffused backward from the lamp 5 to the front.

[0024] It's important to note that the principle behind laser hair removal is that the Sapphire Freezing Point Laser Hair Removal Device uses intense pulsed light (typically a laser of a specific wavelength, such as 800nm) to directly target the melanin in hair follicles deep within the skin. Melanin in hair follicles is dense and absorbs laser light of a specific wavelength best. With the continued application of laser energy, the hair regeneration cells within the follicles are destroyed, causing the follicles to gradually shrink and lose their regenerative capacity. Repeated use of the Sapphire Freezing Point Laser Hair Removal Device can significantly reduce the number and activity of hair follicles, achieving long-lasting or even permanent hair removal. The specific process and principles of laser hair removal are well-known and will not be detailed here.

[0025] In addition, in order to cooperate with heat dissipation, the fan 3 has an air inlet and an air outlet. A through hole is reserved at the top of the frame body 1 and corresponds to the position of the air inlet. The heat dissipation module 4 is composed of a metal heat conducting plate 41, air inlet fins 42, air outlet fins 43 and a heat pipe 44. The end of the metal heat conducting plate 41 is in contact with the heat conducting layer 8, the air inlet fins 42 are located above the through hole, and the air outlet fins 43 are located on the side of the air outlet. When the metal heat conducting plate 41 is heated, the heat will be transferred to the air inlet fins 42, the air outlet fins 43 and the heat pipe 44. When the fan 3 is working, the generated air flow will enter from the position of the air inlet fins 42 and be discharged from the air outlet of the fan 3. When discharged, the air flow will blow directly on the air outlet fins 43 and finally be discharged. The specific air flow path is shown in the attached figure. Figure 5 、 6 shown.
