Description

CROSS-REFERENCE TO RELATED APPLICATIONS This non-provisional application claims priority under 35 U.S.C. § 119(a) to U.S. Provisional Application No. 63/525,581, filed on Jul. 7, 2023, the entire contents of which are hereby incorporated by reference. TECHNICAL FIELD This disclosure relates to a communication device, more particularly to a communication device where a communication main unit is in good thermal contact with a heat dissipation module. BACKGROUND In general, a suspension bracket inside a casing of a communication device is typically used with wall-mounting holes (e.g., keyhole slots) in conjunction with hooks to suspend the main unit. The process of fixing the main unit involves hanging the main unit on hooks through the wall-mounting holes and then pushing the main unit downward to secure it in place. On the other hand, the communication device usually includes a heat sink to dissipate the heat generated by the main unit to the exterior of the casing, and a heat transfer pad is placed between the main unit and the heat sink to serve as a heat transfer medium. However, if the main unit is fixed using the aforementioned wall-mounting method, shear forces may occur between the main unit and the heat transfer pad on the wall, potentially preventing the heat transfer pad from achieving good thermal contact with the main unit, which can affect the heat dissipation efficiency of the heat sink. Therefore, ensuring good thermal contact between the main unit and the heat transfer pad is a challenge for researchers in this field. SUMMARY The present disclosure is to provide a communication device capable of addressing the problem in conventional communication devices where the main unit cannot be in good thermal contact with the heat transfer pad. One embodiment of the present disclosure provides a communication device including a housing assembly, a heat dissipation module and a communication main unit. The housing assembly includes a bottom cover, a mounting bracket and at least one positioning component. The mounting bracket is movably disposed on the bottom cover, and the mounting bracket is movable relative to the bottom cover between an installation position and a pre-installation position via a guiding structure. The positioning component is connected to the bottom cover, and the positioning component is configured to fix the mounting bracket in the installation position in a detachable manner. The heat dissipation module is fixed to the bottom cover, and the heat dissipation module has a heat-absorbing surface. The mounting bracket is located farther away from the heat-absorbing surface when in the pre-installation position than in the installation position. The communication main unit is detachably disposed on the mounting bracket. In addition, when the mounting bracket is in the installation position, the communication main unit is in physical contact with the heat-absorbing surface of the heat dissipation module. According to the communication device as described above, if maintenance personnel want to install the communication main unit within the housing assembly, they may first position the mounting bracket in the pre-installation position, and then, assemble and secure the communication main unit onto the mounting bracket. Subsequently, the maintenance personnel may move both the mounting bracket and the communication main unit to the installation position, ensuring that the communication main unit is in physical contact with the heat-absorbing surface of the heat dissipation module. Therefore, it prevents the communication main unit from coming into direct contact with the heat dissipation module when the communication main unit is pre-assembled on the housing assembly, thereby preventing shear forces between the communication main unit and the heat dissipation module, which ensures that there is good thermal contact between the communication main unit and the heat dissipation module.
