Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ultraviolet curing light source module, especially relates to a water cooling heat dissipation type ultraviolet curing light source module. BACKGROUND

[0002] For optical articles, such as lenses, one or more surfaces can be treated to enhance the overall performance and functionality of the optical article. Examples of such treatments include forming one or more coatings on the surface of the optical substrate. To manufacture coated optical articles from uncoated optical substrates, various manufacturing techniques have been developed. In some treatments, the uncoated optical substrate is first washed and dried, and then a coating is applied on at least one surface of the substrate. For coatings that need to be cured with ultraviolet light, the coated substrate is passed through a curing device having a source of ultraviolet radiation.

[0003] In high-intensity ultraviolet light applications, conventional heat dissipation techniques often cannot effectively solve the problem of overheating of light sources, affecting the efficiency and service life of the equipment. Especially in space-limited environments, it is difficult to provide a more efficient and compact layout of heat dissipation technology for efficient heat dissipation of the equipment, resulting in reduced use efficiency and service life.

[0004] Chinese patent publication No. CN203565309U discloses a UVLED curing device, the curing device contains several curing light source modules, the curing device includes a main body, an ice water machine connected with the main body and a power box connected with the main body, the main body is internally provided with a step part and an intermediate part supporting the curing light source modules, the step part is in a concave shape and is provided with a groove, the intermediate part is arranged in the groove, and a protective cover is further arranged above the curing light source modules. The main body is connected with the ice water machine through the water inlet pipe and the water outlet pipe, the water inlet pipe and the water outlet pipe extend into the groove, and the main body is connected with the power box through the power line. Such a curing device is small in size, saves space, does not affect the heat dissipation effect, and is conducive to the installation and use of the cooling device. Although the patent discloses water cooling, the heat dissipation structure is inconvenient to use, and water leakage and other phenomena are prone to occur.

[0005] Chinese Patent Publication No. CN221122140U relates to the field of UV curing light source technology, and more particularly, to a UV curing light source module for printing light guide plates, comprising a housing, a lamp bead, and a circuit board. The housing has a through hole on the lower end surface for the lamp bead to pass through. The lamp bead is mounted on the lower end of the circuit board, and the lower end of the lamp bead extends to the outside of the housing. The housing has a cover plate mounted on the upper end. A metal plate is disposed between the housing and the cover plate, and the end of the metal plate extends to the outside of the housing. The metal plates include a first metal plate and a second metal plate. When the device is in use, the UV curing light source modules are connected to each other by the first metal plate and the second metal plate to form a whole. Heat generated by the circuit board can be transferred between the first metal plate and the second metal plate. The second metal plate, located on the outermost side, has a large contact area with the air, resulting in good heat dissipation for the entire device, allowing the device to operate normally. Although the patent achieves an effective heat dissipation area by transferring heat between the metal plates, the heat dissipation effect still cannot meet the requirements of use.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] A water-cooled ultraviolet curing light source module according to a preferred embodiment of the present invention; Figure 1-2 As shown, the frame pressure plate 20 is provided with optical glass 70 and a light source aluminum substrate 60. A heat exchanger body 10 is connected to one side of the frame pressure plate. The heat exchanger body and the frame pressure plate are connected by fasteners 50, thereby fixing the light source aluminum substrate between the frame pressure plate and the heat exchanger body. The heat exchanger body is connected to the light source drive terminal 30, which is used to power the light source aluminum substrate so that the light source aluminum substrate is energized and emits light for ultraviolet curing.

[0031] Specifically, such as Figure 1-5As shown, to enhance heat dissipation within the heat exchanger body 10, a water-cooling channel 100 and heat-dissipating wings 101 are provided. The water-cooling channel is located near the aluminum substrate of the light source and includes a water-cooling pipe 1000. Water inlets and outlets 1001 are located on either side of the water-cooling pipe. The water-cooling pipe runs through both sides of the heat exchanger body, and recessed cavities 103 are provided at the inlets and outlets. Cover plates 40 are placed over the recessed cavities to seal the water inlets and outlets, facilitating operation. The heat-dissipating wings 100 are located on the side away from the aluminum substrate of the light source, and a hollowed-out groove 104 is provided in the middle of the wings. This hollowed-out groove gives the upper portion of the heat exchanger body an X-shape, which not only provides a visually striking appearance for the module but also enhances overall mechanical stability through its structural characteristics. The X-shaped structure, through its intersecting design, increases internal space, facilitating the placement of more heat-dissipating wings. The heat dissipation wings utilize a multi-layered, sheet-like heat dissipation structure, arranged like fins. This significantly increases the heat dissipation surface area, optimizes the coolant flow path, and achieves efficient heat exchange. The heat dissipation system utilizes water-cooling channels and heat dissipation wings, consisting of precisely designed water pipes and heat sinks that work closely with the sheet-like heat dissipation structure, ensuring effective control of light source temperature even under continuous operation.

[0032] Furthermore, if Figure 5-6 As shown, the heat exchanger body is provided with a terminal fixing cavity 105, which is provided with a through hole 102 that penetrates the heat exchanger body. The light source drive terminal 30 is placed in the terminal fixing cavity, and the light terminal terminal fixing cavity includes a fixing plate 301 provided in the terminal fixing cavity. The fixing plate is connected to the heat exchanger body via a locking member. The lower end of the fixing plate is provided with an output terminal 300 that is placed in the through hole. The upper end of the fixing plate is provided with an input terminal 304. The input terminal is provided with an outer ring 302. An inner groove 303 is formed between the outer ring and the input terminal. The upper end surface of the input terminal is higher than the upper end surface of the heat exchanger body, so that the input terminal forms a socket-like power interface, achieving fast and secure connection with the power supply and facilitating maintenance and replacement. After the power supply enters and exits the inner groove, it contacts the input terminal, and the electrical signal is transmitted to the light source aluminum substrate 60 through the output terminal, causing the light source aluminum substrate to be powered and illuminated.

[0033] Furthermore, if Figure 7-9As shown, the frame pressure plate 20 is formed by two sets of horizontal side panels 200 and two sets of vertical side panels 201, forming a hollow cavity 202. The lower end of the hollow cavity is provided with a reshaping groove 204. The optical glass 70 is placed in the annular groove. The upper end of the annular groove is provided with a step 203. The light source aluminum substrate 60 is placed on the step, and multiple groups of light source beads 600 are arranged in an array toward the optical glass. Locking holes 205 are provided on both the horizontal and vertical side panels. Locking members are placed in the locking holes to connect and fix the heat exchanger body to the frame pressure plate, thereby fixing the light source aluminum substrate. The locking members can be easily removed by means of locking screws, etc.

[0034] Furthermore, the heat exchanger body 10 is constructed from a highly thermally conductive aluminum alloy and machined to ensure the precision of its X-shaped design and overall heat dissipation efficiency. The heat dissipation structure is designed as a multi-layered structure, each connected by delicate water channels to form an effective heat exchange network, thereby providing a more efficient and compact heat dissipation solution in space-constrained environments.

[0035] It should be understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
