Miniaturized efficient heat dissipation wavelength division multiplexer

Abstract

The invention provides a miniaturized efficient heat dissipation wavelength division multiplexer, relates to the technical field of wavelength division multiplexers, and solves the problem of low heat dissipation efficiency, the miniaturized efficient heat dissipation wavelength division multiplexer comprises a bottom plate and a heat dissipation cover arranged on the bottom plate, one end of the heat dissipation cover is provided with a leading-in terminal, the other end of the heat dissipation cover is provided with a leading-out terminal, and a supporting frame fixed on the bottom plate is arranged in the heat dissipation cover. Component fixing seats which are symmetrically arranged on the two sides of the supporting frame are arranged on the bottom plate, a motor is arranged at one end of the supporting frame, a rotating shaft which penetrates from one end of the supporting frame to the other end of the supporting frame is arranged on a transmission shaft of the motor through a bearing, and a first cooling fan which is correspondingly arranged between the two component fixing seats is arranged in the middle of the rotating shaft; when the cooling fan rotates, the component is driven to move up and down through a gear linkage mode and a lifting rod, so that when the high temperature of the component occurs, the purpose of receiving heat dissipation treatment in a swinging mode is achieved, and due to the fact that the component also swings during heat dissipation, air circulation can be accelerated, and the heat dissipation efficiency of the component can be improved.

Description

technical field [0001] The invention relates to the technical field of wavelength division multiplexers, in particular to a wavelength division multiplexer with miniaturization and efficient heat dissipation. Background technique [0002] A wavelength division multiplexer is a communication that combines a series of optical signals carrying information but with different wavelengths into one bundle, transmits them along a single optical fiber, and then uses a certain method at the receiving end to separate the optical signals of different wavelengths. technology, this technology can transmit multiple signals on one optical fiber at the same time, in order to make the existing wavelength division multiplexer easy to install, the Chinese patent of patent No. CN202110770248.6 discloses a wavelength division multiplexer The utility model comprises: a wall fixing plate, a transfer box and a split box, the transfer box and the split box are connected to the wall fixing plate throu...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from the above-mentioned patent that although the disclosed WDM is easy to install and dismantle, the WDM will generate relatively high heat during operation, and the above-mentioned WDM is radiated and cooled by a cooling fan. However, when the components assembled in the box are affected by high temperature, the gas discharged by the cooling fan can only act on the local parts of the components. Through the way of dissipating heat at the local positions first, it will slowly dissipate heat, resulting in its overall cooling time Longer, lower cooling efficiency
