Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of medical devices, and in particular to a high-end medical aesthetic hair removal handheld laser. Background Technology
[0002] Lasers used for hair removal on the market are relatively large. With the widespread application of high-power laser technology in fields such as medical aesthetics and precision machining, the thermal management of the laser's core component—the laser bar—has become increasingly prominent. During photoelectric conversion, the laser bar, as the core device for energy conversion, generates a significant amount of waste heat during operation. Studies have shown that nearly half of the input electrical energy fails to be effectively converted into light energy, instead accumulating as heat inside the device. This high heat flux density poses a severe challenge to the heat dissipation system. Traditional heat dissipation solutions often struggle to achieve rapid and uniform heat removal within a limited space, leading to a sharp rise in the bar's temperature, which in turn causes wavelength drift, output power attenuation, and even permanent damage to the device.
[0003] In the field of medical aesthetic equipment, the miniaturization of laser modules is particularly urgent. Due to limitations in ergonomics and operational flexibility, handheld hair removal devices, skin treatment devices, and similar equipment typically require highly integrated laser modules, often compressing their internal space to an extremely compact size. However, conventional heat dissipation technologies face a fundamental contradiction: forced air cooling solutions, while simple in structure, struggle to match the heat dissipation efficiency of kilowatt-level heat loads, and the fan noise and size cannot meet the quiet operation requirements of medical devices; while plate-type water cooling structures can improve heat dissipation capacity, their complex flow channel design and size constraints make them unsuitable for miniaturized packaging requirements. This conflict between space constraints and heat dissipation needs forces many designs to reduce laser operating power or sacrifice device reliability, severely hindering the widespread application of high-power laser technology in portable medical devices.
[0004] The limitations of existing heat dissipation architectures are mainly reflected in two aspects:
[0005] Firstly, the traditional straight or serpentine water channel design leads to uneven coolant flow, making it difficult to eliminate local hot spots. The contact thermal resistance between the heat sink substrate and the bar further exacerbates the temperature gradient.
[0006] Secondly, the integration of the heat dissipation module and the electrical system lacks coordinated design, and the physical contact between conductive components and the heat dissipation structure is prone to electromagnetic interference and insulation failure risks. To address these issues, a high-end medical aesthetic hair removal handheld laser is proposed. Utility Model Content
[0007] (a) Technical problems to be solved
[0008] To address the shortcomings of existing technologies, this invention provides a high-end medical aesthetic hair removal handheld laser that solves the technical problem of heat dissipation in a small area.
[0009] (II) Technical Solution
[0010] To achieve the above objectives, this utility model provides the following technical solution:
[0011] A high-end medical aesthetic hair removal handheld laser, including
[0012] The laser's rear shell and front shell are fixedly connected by bolts. The outer side of the laser's front shell is connected to the hair removal handle. During use, a heat dissipation mechanism is installed inside the laser's front shell. Two sets of insulating blocks are installed on the outer side of the laser's rear shell. One end of two sets of conductive copper busbars is installed in the insulating blocks by bolts. A bar is installed inside the laser's front shell. The other end of the conductive copper busbar is fixedly connected to the bar. The bar is the core component for photoelectric conversion.
[0013] Preferably, the bar has a printed circuit inside, and electrical energy is transferred to the printed circuit by the conductive copper busbar and then distributed to the bar module. The conductive copper busbar has no direct contact with the front shell of the laser. The energy that is not effectively utilized in the photoelectric conversion is dissipated in the form of heat and efficiently discharged by the integrated water-cooling circulation module.
[0014] Preferably, a water channel component is fixedly installed inside the rear shell of the laser. The water channel component has a cavity structure to accommodate the core photoelectric conversion device.
[0015] Preferably, a honeycomb mesh water channel is provided between the water channel component and the bar, and the honeycomb mesh water channel is connected to the external water channel to achieve heat dissipation for the water channel component and the bar.
[0016] Preferably, after the laser rear shell and laser front shell are merged, a water outlet channel and a water inlet channel are formed. The water outlet channel and the water inlet channel are respectively connected to both ends of the honeycomb mesh water channel to realize the circulation of water flow. The water inlet channel is connected to the external water supply equipment to realize water supply, and the water outlet channel is connected to the external drainage equipment to realize the discharge of the circulating water flow.
[0017] (III) Beneficial Effects

Overall cooling and heat dissipation process description: The inclined inlet and outlet reduce the volume occupied by the piping; circulating water enters the laser through the inlet channel, circulates into the gaps of the honeycomb mesh water channel to lower the laser temperature, and the warm water is discharged through the outlet channel; by designing the inlet and outlet as inclined water channels and incorporating the honeycomb mesh heat dissipation structure, a small size, high heat dissipation efficiency, and high material utilization are achieved.

The conductive copper busbars 2 have no direct contact with the laser front shell 8. Energy not effectively utilized in photoelectric conversion is dissipated as heat and efficiently discharged by an integrated water-cooling circulation module.
[0029] A water channel component 3 is fixedly installed inside the rear shell 7 of the laser.

[0030] like Figure 4 As shown, after the laser rear shell 7 and the laser front shell 8 are merged, a water outlet channel 9 and a water inlet channel 10 are formed.
