Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for communication modules, specifically a heat dissipation device for foldable communication modules. Background Technology

[0002] A foldable communication module heat dissipation device is a device that optimizes size and heat dissipation efficiency through folding or movable structures, primarily used for thermal management of communication modules (such as optical modules and wireless communication modules). Size reduction is achieved through hinges, rotating structures, or elastic materials, facilitating storage and transportation. Existing heat dissipation devices combine cooling fins, finned heat sinks, and cooling fans to achieve better heat dissipation.

[0003] Existing cooling fans are thermally fixed to finned heatsinks, tightly adhering to the fins. This compresses the airflow through the fins, increasing airflow resistance, reducing heat dissipation efficiency, and causing localized overheating of the heatsink. Furthermore, when the fan blades are too close to the heatsink fins, resonance can occur due to airflow turbulence or mechanical vibration, significantly increasing noise. Therefore, a foldable communication module cooling device is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation device for a foldable communication module, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution: This utility model is a heat dissipation device for a foldable communication module, comprising: A heat dissipation assembly, comprising a cooling plate, a finned heat sink, and a cooling fan, wherein there are two cooling plates connected by a hinge, the finned heat sink is fixed on the cooling plate, and the cooling fan is fixed on the finned heat sink; The current amplification assembly includes an L-shaped mounting plate, a first threaded hole, a fixing plate, a through hole, a bolt, a limiting nut, and a fastening nut. The L-shaped mounting plate is fixed to the middle of both ends of the finned heat sink. The first threaded hole is opened in the middle of one side of the L-shaped mounting plate. The fixing plate is fixed to the middle of both ends of the cooling fan. The through hole is opened in the middle of the fixing plate. The bolt is screwed into the first threaded hole. The limiting nut and the fastening nut are screwed into the end of the bolt near the fixing plate.

[0005] Furthermore, the inner diameter of the first threaded hole is smaller than the inner diameter of the through hole, and one end of the bolt is inserted into the through hole.

[0006] Furthermore, the limiting nut and the fastening nut are located on both sides of the fixing plate, and the limiting nut is located between the L-shaped mounting plate and the fixing plate.

[0007] Furthermore, the heat dissipation assembly also includes an L-shaped slot, which is fixed on the cooling plate, and the finned heat sink is inserted into the L-shaped slot and fastened with screws.

[0008] Furthermore, the cooling chip and the cooling fan are connected to an external power source via a power cord.

[0009] Furthermore, it also includes a stabilizing component, which includes a second threaded hole, an adjusting screw, a bearing, and a U-shaped locking block. The second threaded hole is opened at both ends of the middle part of the cooling fan. The adjusting screw is screwed into the second threaded hole. The inner ring of the bearing is fixed to one end of the adjusting screw, and the outer ring is fixed to the side of the U-shaped locking block. The other side of the U-shaped locking block away from the adjusting screw is locked onto the finned heat sink.

[0010] Furthermore, the stabilizing component also includes a shock-absorbing pad, which is fixed to the inside of the U-shaped block and attached to the finned heat sink.

[0011] Compared with the prior art, the foldable communication module heat dissipation device of this utility model has the following advantages: This invention, through its airflow-expanding component, allows for efficient installation of the heat dissipation assembly. First, the cooling fins are unfolded and fixed to the communication module. Bolts are screwed into the first threaded hole of the L-shaped mounting plate, and the upper limit nut is tightened. Then, the bolts are passed through the through hole of the fixing plate, and the fastening nut is tightened. The finned heat sink is inserted into the L-shaped slot, and the screws are tightened. Rotating the bolts by both hands moves the upper limit nut and the fastening nut, thereby moving the fixing plate and the cooling fan. Once adjusted to a suitable space for the communication module installation, the movement stops, and the fastening nut is tightened again. This design maximizes the airflow between the finned heat sink and the cooling fan, preventing airflow obstruction. Attached Figure Description
