Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display modules, and more specifically, to a heat dissipation structure for a liquid crystal display module. Background Technology

[0002] A liquid crystal display (LCD) module is the core component of liquid crystal display technology. It is assembled from a complex system of components including liquid crystal display devices, connectors, peripheral control and driving circuits, printed circuit boards (PCBs), backlights, structural components, and polarizers. The working principle of an LCD module is based on the physical properties of liquid crystal molecules. When a voltage is applied to the electrodes, the liquid crystal molecules change, thereby altering the light transmittance of the liquid crystal and achieving the display effect.

[0003] The prior art disclosed in patent publication (announcement) number CN222322073U is a heat dissipation structure for a liquid crystal display module, including a liquid crystal display screen. A back cover is provided on the back of the liquid crystal display screen. A heat dissipation groove is formed on the upper end of the surface of the back cover. A cooling box is installed on the lower end of the surface of the back cover. Cooling fans are installed on both the left and right sides of the surface of the cooling box. A semiconductor cooling chip is installed on the back of the cooling box. A heat exchange plate is provided on the inner side of the cooling box. A filter screen is provided on the inner side of the cooling box at the edge of the heat exchange plate.

[0004] The aforementioned patent document discloses a heat dissipation structure for a liquid crystal display module, which can solve the problems of poor heat dissipation and susceptibility to environmental influences in the prior art. However, the water-cooling structure in the patent has many components, which not only increases the processing difficulty but also increases the overall cost. Its shortcomings are:

[0005] In the liquid crystal display module heat dissipation structure disclosed in the above patent documents, although the combination of water cooling and heat dissipation fan effectively improves the heat dissipation performance, after long-term use, dust easily accumulates on the surface of the heat exchange plate. This dust will hinder the effective transfer of heat and thus affect the efficiency of the entire heat dissipation system.

[0006] Furthermore, while the device achieves good heat dissipation, its complex structure also brings inconvenience in disassembly and maintenance. The high degree of integration of components such as the semiconductor cooling chip, cooling fan, and heat exchanger makes it difficult to disassemble when internal maintenance or replacement of parts is required, often requiring a lot of time and effort.

[0007] Therefore, we have made improvements and proposed a heat dissipation structure for liquid crystal display modules. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

This not only improves heat dissipation efficiency but also greatly simplifies the cleaning process.

[0022] 2. The sliding connection design between the fixed cylinder and the fixed rod, achieved through the use of a connecting mechanism, not only ensures the flexibility and precision of the heat dissipation module during installation but also enables the entire structure to maintain good stability under external forces. Furthermore, the threaded connection of the screws inside the fixed rod further enhances the tightness between the heat dissipation structure and the base plate, effectively preventing loosening due to vibration or long-term use. This connecting mechanism makes maintenance or disassembly exceptionally simple, significantly saving time and reducing maintenance costs. Attached Figure Description
