Description

Technical Field

[0001] This utility model relates to the field of water cooling applications, and in particular to a miniature ultraviolet laser device integrated with water cooling components. Background Technology

[0002] Ultraviolet lasers (typically with a wavelength of 355 nm) can directly break molecular bonds in materials ("cold processing") due to their shorter wavelength and higher photon energy, reducing the heat-affected zone and achieving ultra-high precision (micrometer-level) marking. They are particularly suitable for brittle, highly reflective, or heat-sensitive materials (such as glass, ceramics, plastics, and semiconductors). With advancements in semiconductor pumping technology (DPSS) and compact optical design, ultraviolet lasers have become smaller and more energy-efficient, facilitating integration into automated production lines or portable devices. Furthermore, the development of high-precision galvanometers, high-speed control cards, and software algorithms (such as real-time path optimization) has enabled small ultraviolet devices to achieve complex patterns and dynamic marking, meeting personalized customization needs.

[0003] Laser marking generates a significant amount of heat, which can affect marking accuracy. Existing cooling methods involve cooling systems, such as large air-cooled or water-cooled equipment. However, these additional cooling systems, when integrated with the laser equipment, result in an overly bulky device that is difficult to move and requires cumbersome assembly and maintenance.

[0004] In view of this, this technical solution proposes a miniature ultraviolet laser device with integrated water-cooling components. The ultraviolet laser device and water-cooling components are integrated into a single device, and instant cooling is achieved through an internal liquid cooling heat exchange structure. This solves the problem of large space occupation in traditional methods and is easy to carry, assemble, and maintain. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide a miniature ultraviolet laser device integrated with a water-cooling component, thereby addressing the problems of existing ultraviolet laser devices lacking an integrated water-cooling structure, having a large overall structure, being difficult to carry and transport, and being difficult to assemble and maintain.

[0006] To achieve the above objectives, this utility model provides a miniature ultraviolet laser device integrated with a water-cooling component, including an outer housing assembly, and a laser body and a liquid-cooling component disposed within the outer housing assembly.

[0007] The external housing assembly is formed by a top cover, a front panel, a rear panel, a bottom plate, and side panels on both sides.

[0008] The laser body is positioned above the top cover, and a temperature-conducting plate is located at the bottom of the laser body, with the bottom of the temperature-conducting plate in contact with the cooling coal plate. A heat exchange plate is located on one side of the cooling coal plate.

[0009] The liquid cooling assembly includes a water tank, a water inlet and a water pump disposed on the water tank, and the water tank is also connected to a compressor with a condenser via a pipeline. The compressor is connected to the heat exchange plate via a pipeline.

[0010] As a further embodiment of this utility model, the rear panel is provided with a laser interface panel corresponding to the position of the laser body, as well as a water outlet and a water return port that are respectively connected to the water tank and the heat exchange plate. A power interface, an air outlet, and a data interface are also provided on one side of the rear panel.

[0011] As a further improvement of this utility model, an air inlet is provided on the side plate.

[0012] As a further improvement of this utility model, the front panel is provided with a water-cooling switch, a laser switch, a laser indicator light, and a plug.

[0013] As a further improvement of this utility model, the top cover is provided with a handle for easy carrying of the device.

[0014] As a further improvement of this utility model, a power filter is provided on one side of the cooling coal plate.

[0015] As a further embodiment of this invention, the liquid cooling assembly also includes a filter connected between the water pump and the water tank.

[0016] The beneficial effects of this utility model are as follows:

[0017] This technical solution addresses the problems of bulky size, difficult handling, and cumbersome assembly and maintenance caused by external cooling systems in traditional ultraviolet laser equipment. It achieves a breakthrough improvement through highly integrated design. Traditional equipment relies on independent air-cooling or water-cooling systems, requiring complex piping connections, occupying additional space, and prone to issues such as loose interfaces and uneven heat dissipation. This solution integrates the laser body and liquid cooling components into a single housing. The bottom heat-conducting plate of the laser is directly attached to the refrigerant plate. A water pump in the liquid cooling component drives the coolant circulation. The low-temperature coolant is cooled by the compressor and condenser, and then the refrigerant plate absorbs the heat transferred from the heat-conducting plate. The heated liquid flows back to the water tank for recooling via a heat exchange plate, forming a closed-loop, highly efficient heat dissipation system that significantly reduces the impact of heat accumulation on accuracy. The housing structure further optimizes integration capabilities. The rear panel centrally houses the laser interface panel, water outlet, water return, power interface, air outlet, and data interface, simplifying external wiring and supporting rapid coolant release and recycling. The side panel air inlets and outlets create air convection to aid in the removal of excess heat. The front panel integrates a water-cooling switch, laser switch, and indicator lights, enabling one-button operation and status monitoring. The top cover handle facilitates one-handed carrying, meeting mobility needs. A power filter on the refrigerant plate side eliminates electromagnetic interference, and a filter between the water pump and water tank intercepts impurities, preventing pipe blockage or component wear. Through this modular and standardized design, this solution reduces size to a portable level while maintaining efficient heat dissipation and ease of operation, significantly reducing assembly complexity and maintenance costs. It is particularly suitable for automated production lines or scenarios requiring frequent relocation. Attached Figure Description

[0029] as follows:

[0030] Please see the appendix Figure 1-8 ,

[0031] The main structure includes an outer shell assembly (1), a laser body (2) and a liquid cooling assembly (4) set inside the outer shell assembly (1). The outer shell assembly (1) is formed by a top cover (10), a front panel (11), a rear panel (12), a bottom plate (14) and side panels (13) on both sides. The laser body (2) is located above the top cover (10). A temperature guide plate (20) is provided at the bottom of the laser body (2). The bottom of the temperature guide plate (20) is in contact with the cooling plate (3). A heat exchange plate (30) is provided on one side of the cooling plate (3). The liquid cooling assembly (4) includes a water tank (40), a water inlet (42) and a water pump (41) provided on the water tank (40). The water tank (40) is also connected to a compressor (44) connected to a condenser (45) through a pipeline. The compressor (44) is connected to the heat exchange plate (30) through a pipeline.

[0032] The working principle is as follows:

[0033] This technical solution, through its highly integrated design, effectively solves the problems of large size, difficult handling, complex assembly, and inconvenient maintenance caused by the external cooling system in traditional ultraviolet laser equipment.

[0034] In existing technologies, ultraviolet lasers typically rely on independent air-cooling or water-cooling systems for heat dissipation. These external cooling devices not only occupy extra space but also require complex piping connections to the laser equipment, resulting in a bulky overall structure that is difficult to meet portability requirements. Furthermore, the split design increases assembly steps and maintenance difficulty, leading to frequent problems such as loose piping interfaces and poor compatibility between the cooling system and the laser equipment, thus affecting efficiency. This technical solution achieves a compact layout by integrating the liquid cooling component (4) and the laser body (2) into the same housing. Specifically, the laser body (2) is located below the top cover (10) of the housing, with its bottom heat-conducting plate (20) directly attached to the refrigerant plate (3), which is connected to the liquid cooling component (4) via a heat exchange plate (30). The water pump (41) of the liquid cooling component (4) drives the coolant from the water tank (40) through the compressor (44) and condenser (45) to form a low-temperature circulation. The cooling plate (3) transfers the low temperature to the heat-conducting plate (20), which quickly absorbs the heat generated by the laser. Then, the heat exchange plate (30) sends the heated coolant back to the water tank (40) through the return port (122) for recooling. This closed-loop design not only saves the space of external cooling equipment, but also achieves instant heat dissipation through efficient internal heat exchange, significantly reducing the impact of heat accumulation on laser accuracy.

[0035] The shell structure further optimizes the advantages of the integrated design. The rear panel (12) integrates the water outlet (121) and the water return (122), which can directly release the cooled liquid and recover the heated liquid, avoiding the cumbersome external piping. The side panel (13) has an air inlet (130) to assist air circulation, which, together with the air outlet (124), forms a natural heat dissipation supplement. The front panel (11) centrally arranges the water-cooled switch (110), the laser switch (111), and the indicator light (112), simplifying the operation process. The top cover (10) has a handle (100) for easy overall equipment handling, meeting the needs of mobility. In addition, the filter (43) added to the liquid cooling component (4) can prevent impurities from clogging the pipeline, and the power filter (31) reduces the impact of electromagnetic interference on laser stability. All functional modules are installed with standardized interfaces and embedded structures, which greatly simplifies the assembly process. Later maintenance only requires component replacement or cleaning for a single device, significantly reducing maintenance costs. Through the above integrated and modular design, this technical solution reduces the size of the equipment to a portable level while ensuring efficient cooling performance, taking into account both industrial-grade precision and flexible deployment capabilities, making it particularly suitable for automated production lines or on-site operation scenarios.

A power interface (125), an air outlet (124), and a data interface (123) are also provided on one side of the rear panel (12).

[0037] The rear panel (12) of this solution is designed with highly integrated multiple functional interfaces, significantly improving the ease of use of the equipment. The laser interface panel (120) corresponds to the position of the upper laser body (2), which facilitates quick connection to external laser output devices or optical fibers, ensuring stable signal transmission. The water outlet (121) and the water return port (122) are respectively connected to the water tank (40) and the heat exchange plate (30) to form a coolant circulation channel. The water outlet (121) can directly release the cooled coolant, while the water return port (122) recovers the heated liquid to the water tank (40) for recooling, eliminating the trouble of connecting complex external pipelines. The power interface (125) provides stable power supply to the equipment. The air outlet (124) works with the air inlet (130) of the side panel (13) to form air convection, which helps to exhaust internal waste heat. The data interface (123) supports the access of external control devices or software to realize remote operation or parameter adjustment. By centrally arranging the core functional interfaces, the external wiring of the equipment is simplified, and it is also convenient to quickly locate the problematic parts during maintenance.

[0039] An air inlet (130) is provided on the side panel (13), forming an air convection channel with the air outlet (124) on the rear panel (12). External cold air flows into the equipment from the air inlet (130), assisting the liquid cooling system in dissipating the waste heat generated by the laser and electronic components, thus preventing heat accumulation from affecting performance. This design enhances the overall heat dissipation efficiency through natural airflow circulation without increasing the size, ensuring stable operation of the equipment for a long time.

Users can start and stop the cooling system with one button via the water-cooling switch (110), and control the laser output via the laser switch (111). The indicator light (112) displays the laser's working status in real time (such as running or malfunctioning), facilitating quick identification of the equipment status. The plug (113) is used to seal unused interfaces or reserved holes to prevent dust from entering or liquid from leaking, ensuring the cleanliness and sealing of internal components.

[0043] This design incorporates a handle (100) on the top cover (10), which, through ergonomic design, allows users to easily hold and move the equipment with one hand, making it particularly suitable for scenarios requiring frequent movement or on-site operations. The handle (100) is integrally molded with the housing, maintaining structural stability while avoiding additional protrusions that occupy space, ensuring portability without compromising the overall compactness of the equipment.

[0044] Reference Appendix Figure 6 In a preferred embodiment of this utility model, a power filter (31) is provided on one side of the cooling plate (3).

[0045] The power filter (31) is used to eliminate electromagnetic noise interference in the power supply line, prevent power fluctuations from affecting the stability of the laser and cooling system, thereby improving the operating accuracy of the equipment and extending the life of the core components.

[0046] Reference Appendix Figure 8 In a preferred embodiment of the present invention, the liquid cooling assembly (4) further includes a filter (43) connected between the water pump (41) and the water tank (40).

[0047] A filter (43) is installed between the water pump (41) and the water tank (40) of the liquid cooling assembly (4) to intercept impurities or tiny particles in the coolant, preventing them from entering precision components such as the water pump (41) and compressor (44) during circulation and causing blockage or abnormal wear, thereby ensuring the long-term stable operation of the cooling system. The filter (43) also prevents impurities from depositing in the heat exchange plate (30) or pipelines, affecting heat dissipation efficiency, reducing maintenance needs caused by contamination, and further improving the overall reliability and service life of the equipment.
