Method for making heat radiation treating of device with radiation structure in communication equipment

Abstract

This invention discloses a method for radiation by a radiating device in communication equipment including: setting a device with a radiation structure on a PCB and making the other face opposite to the validation face match with the PCB, designing a radiator on the said radiation structure and fixing it at the PCB circuit to suppress the device to effectively contact with the PCB. This invention unitizes the internal space of the device and air counterflow and PCB for radiation.

Description

technical field [0001] The invention relates to a heat dissipation treatment method for a device with a heat dissipation structure in a communication device. Background technique [0002] With the continuous emergence of low-voltage devices in communication equipment, various devices with heat dissipation structures are widely used, such as a typical voltage regulator (Voltage Regulator). In equipment with complex power supplies, the voltage regulator has become one of the key components for the reliable operation of the system. During the development process, designers need to consider various methods to ensure long-term stable and reliable operation of the voltage regulator. [0003] One type of voltage regulator is a linear voltage regulator (Linear Voltage Regulator), which can flexibly implement various voltage regulation designs. The working mode of the linear voltage regulator is shown in Figure 1. When this type of voltage regulator is working, the voltage differe...

AI Technical Summary

Problems solved by technology

[0010] 1. Inconvenient structural design

If the linear voltage regulator is upright on the PCB, the height of the voltage regulator itself, plus the height of the heat sink, needs to occupy a large space, which has certain requirements for the internal structure design of communication equipment.

Moreover, when the voltage regulator is located on a single board that needs to be moved frequently, such as a plug-in board, the voltage regulator may interfere with the equipment shell and other components

[0011] 2. Poor security

During severe vibration or transportation, the bolts are easy to come off, causing a short circuit on the board

[0012] 3. Poor cooling effect

The voltage regulator uses the PCB to dissipate heat. Due to the limited ability of the PCB to conduct heat dissipation, the current passing through the voltage regulator is also limited accordingly.
