[0015] The beneficial effects of the utility model are:

[0016] Compared with the existing phototherapy device housing, the present invention adopts a die-cast housing formed by a metal die-casting process, which not only ensures the sturdiness and durability of the phototherapy device structure, but also fully utilizes the high thermal conductivity of metal materials. This feature makes the housing itself an efficient heat conduction carrier, which can quickly diffuse the heat generated inside to the outside, effectively reducing the operating temperature of the internal components. The multiple carefully designed placement grooves on the die-cast housing not only provide a stable and reliable installation platform for the light module. Each placement groove is equipped with heat dissipation fins on the inner periphery. These fins increase the heat exchange area, allowing heat to be convectively exchanged with the surrounding air more quickly during the process of conduction through the housing, thereby significantly improving the heat dissipation efficiency. The use of heat dissipation fins also further enhances the active heat dissipation capacity of the heat dissipation structure. When the phototherapy device is working for a long time or under high load, the heat dissipation fins can effectively disperse and carry away the concentrated heat generated by the light module, avoiding the occurrence of local overheating, protecting the light module and other electronic components from high temperature damage, and extending the overall service life of the equipment.

The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0023] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are only for the purpose of describing specific embodiments and are not intended to limit this invention. Figures 1 to 4As shown, one embodiment of the present invention relates to a heat dissipation structure for a phototherapy device. The structure comprises a die-cast housing 10 formed by metal die-casting. The housing 10 is provided with multiple mounting slots 1 for mounting a light module 2. Heat dissipation fins 11 are arranged along the inner circumference of the mounting slots 1 to dissipate heat from the light module 2. This embodiment utilizes a metal die-casting process to form the housing 10, ensuring the structural strength and durability of the phototherapy device while also fully utilizing the high thermal conductivity of metal. This property makes the housing itself an efficient heat transfer medium, rapidly dissipating internally generated heat to the outside, effectively reducing the operating temperature of internal components. The multiple carefully designed mounting slots 1 on the die-cast housing 10 provide a stable and reliable mounting platform for the light module 2. Each mounting slot 1 is also equipped with heat dissipation fins 11 along its inner circumference. These fins increase the heat exchange area, allowing heat to be more rapidly convectively exchanged with the surrounding air during conduction through the housing, significantly improving heat dissipation efficiency. The use of heat dissipation fins 11 further enhances the active heat dissipation capability of the heat dissipation structure. When the phototherapy device is working for a long time or under high load, the heat dissipation fins 11 can effectively disperse and take away the concentrated heat generated by the light module 2, avoiding local overheating, protecting the light module 2 and other electronic components from high temperature damage, and extending the overall service life of the device.

[0025] The edge of the die-cast housing 10 is provided with a mounting edge 3, and connecting ribs 31 are provided between the mounting edge 3 and the mounting groove 1. In this embodiment, the addition of the mounting edge 3 enhances the stability of the housing edge, effectively preventing edge damage or deformation caused by external forces, thereby improving the overall durability and service life of the phototherapy device. Secondly, the connecting ribs 31 serve as a bridge between the mounting edge 3 and the mounting groove 1, not only strengthening the connection strength between the two, but also facilitating heat transfer and improving the heat dissipation effect.

[0026] Connecting posts 4 are provided at the corners of the die-cast housing 10 near the mounting edge 3. These posts are used to secure the die-cast housing 10. In this embodiment, these posts 4 serve as fixed mounting points for the die-cast housing 10, significantly enhancing the stability of the connection between the housing and the main structure of the phototherapy device, ensuring that the housing remains stable and does not shake during use, thereby improving the overall durability and safety of the device.

[0027] A fixing ring 12 is provided on the periphery of the placement groove 1, and a plurality of heat dissipation fins 11 are provided, and the plurality of heat dissipation fins 11 are evenly distributed circumferentially on the inner diameter of the fixing ring 12. In this embodiment, the fixing ring 12 serves as a supporting and positioning component, effectively preventing the heat dissipation component from loosening or shifting, ensuring the accuracy and safety of the phototherapy device during operation. At the same time, the circumferential uniform distribution design of the heat dissipation fins 11 greatly improves the heat dissipation efficiency. By increasing the heat dissipation area, the heat generated during the phototherapy process is quickly dissipated, effectively avoiding overheating of the device and ensuring the stable operation and long life of the electronic components inside the phototherapy device.

[0028] The plurality of placement grooves 1 are arranged in a linear array on the die-cast housing 10. Specifically, a through groove 13 is provided between two adjacent placement grooves 1. The through groove 13 is used to fix the bracket of the lampshade. In this embodiment, the lighting module 2 includes a control board 21 and a plurality of wicks 22 arranged on the control board 21, and the wicks 22 are arranged in the placement groove 1. The wicks 22 are provided with a fixed lampshade 23, and the fixed lampshade 23 is arranged in the placement groove 1. Specifically, a lens 24 is provided on the fixed lampshade 23. In this embodiment, not only is the space utilization optimized, but also a stable fixing point is provided for the lampshade bracket through the through grooves 13 cleverly provided between adjacent placement grooves 1. These through grooves 13 serve as connecting bridges to ensure the accuracy and stability of the lampshade installation, and effectively avoid the problem of loosening caused by vibration or long-term use. The linear array placement groove 1 design facilitates uniform heat distribution and dissipation, which helps to improve the heat dissipation efficiency of the phototherapy device, ensure the stable operation of the light source assembly and extend the service life.

[0029] The die-cast housing 10 is formed by integral die-casting of an aluminum alloy. In this embodiment, the aluminum alloy material has excellent thermal conductivity, which helps dissipate heat from the internal components of the phototherapy device, ensuring that the device maintains a stable operating temperature during long-term use and extending its service life. Secondly, the integral die-casting process ensures the strength and sealing of the housing. The integrated design of the aluminum alloy housing simplifies the production process and reduces assembly steps, thereby reducing production costs and improving production efficiency.

[0030] A panel 5 is provided on the side of the die-cast housing 10 facing away from the receiving slot 1. In this embodiment, the die-cast housing 10, with its excellent density and mechanical strength, provides a stable and durable protective barrier for the phototherapy device, effectively resisting impact and erosion from the external environment and ensuring the stable operation of the device's precision components. The provision of panel 5 not only enhances the phototherapy device's aesthetics but also allows the user to intuitively and conveniently operate the device, adjust treatment parameters, and observe treatment results in real time, improving the accuracy and comfort of the treatment process.

[0031] The above embodiments merely illustrate several implementations of the present invention.
