The embodiment of the utility model as shown in fig. 1 and 2 provides a heat dissipation device 100 of a erbium-doped fiber amplifier, which comprises a heat conduction frame 110, a heat pipe 120 and heat dissipation fins 130, wherein one side surface of the heat conduction frame 110 is used for arranging the erbium-doped fiber amplifier, the heat pipe 120 is arranged on the other side surface of the heat conduction frame 110, the heat pipe 120 and the erbium-doped fiber amplifier have overlapping areas on the orthographic projection of the heat conduction frame 110, the heat dissipation fins 130 are arranged on the heat conduction frame 110, and the heat pipe 120 is clamped between the heat conduction frame 110 and the heat dissipation fins 130.
Specifically, the heat conducting frame 110 is used as a base for installing the erbium-doped fiber amplifier, not only plays a role in supporting and fixing the erbium-doped fiber amplifier, but also plays a role in conducting heat, so that heat generated by the erbium-doped fiber amplifier can be timely conducted to the heat conducting frame 110 and transferred to the heat pipe 120 through the heat conducting frame 110, and finally, the heat is dissipated from the heat radiating fins 130 to the external environment, so that the purpose of inhibiting the temperature rise of the erbium-doped fiber amplifier is achieved.
The heat pipe 120 is a device for transferring heat by liquid circulation, and is generally composed of a sealed metal pipe and an internally filled working fluid (generally in a liquid state). The working fluid corresponding to the erbium-doped fiber amplifier in the heat pipe 120 is partially evaporated into a gaseous state after being heated, and then is condensed again into a liquid state at the cold end of the heat pipe 120, and then flows back to the initial position. In this process, the heat pipe 120 transfers heat from one place to another to achieve uniform distribution of heat or efficient heat dissipation. So that heat generated at the heat source is rapidly transferred to the entire area of the heat radiation fins 130 to enhance heat radiation efficiency.
It should be noted that, the heat pipe 120 and the erbium-doped fiber amplifier have overlapping areas on the front projection of the heat conducting frame 110, which is favorable for reducing the heat transfer path between the erbium-doped fiber amplifier and the heat pipe 120, so that the heat generated by the erbium-doped fiber amplifier is timely conducted to the heat pipe 120, avoiding the aggregation of the heat, and being favorable for improving the heat dissipation efficiency.
According to the heat dissipation device 100 of the erbium-doped fiber amplifier provided by the embodiment of the application, the erbium-doped fiber amplifier and the heat pipe 120 are arranged on the opposite side surfaces of the heat conduction frame 110, heat generated when the erbium-doped fiber amplifier works can be timely conducted to the heat conduction frame 110, and then the heat is conducted to other areas through the heat pipe 120 arranged on the heat conduction frame 110, so that the heat dissipation of the heat pipe 120 is realized by fully utilizing the heat dissipation fins 130 matched with the heat pipe 120, the continuous evaporation and condensation state conversion of working fluid in the heat pipe 120 is realized, the continuous high-efficiency heat conduction of the heat pipe 120 is ensured, the heat generated by the erbium-doped fiber amplifier is prevented from being concentrated at a certain place under the matching of the heat pipe 120 and the heat dissipation fins 130, and the heat is dissipated through the heat dissipation fins 130 while being dispersed by the heat pipe 120.

Specifically, a side of the heat pipe 120 is connected with the heat conducting frame 110 through soldering, which is favorable for improving the compactness of contact between the side of the heat pipe 120 and the heat conducting frame 110, avoiding the existence of a gap between the heat pipe 120 and the heat conducting frame 110, and being favorable for ensuring the stability and the heat conduction efficiency of heat conduction. Similarly, the connection between the other side of the heat pipe 120 and the heat dissipation fins 130 through soldering is beneficial to improving the contact tightness between the other side of the heat pipe 120 and the heat dissipation fins 130, avoiding the gap between the heat pipe 120 and the heat dissipation fins 130, and ensuring the stability and the heat conduction efficiency of heat conduction. In addition, through tin welded connection, when guaranteeing heat transfer efficiency, can also play the effect of connection, need not to additionally adopt the fastener to connect, be favorable to saving the cost, reduce process flow, promote assembly efficiency.
As shown in fig. 2 and 3, the heat dissipation fins 130 include a limiting bar 132 and a plurality of L-shaped heat dissipation plates 134, wherein one side of each of the L-shaped heat dissipation plates 134 is arranged side by side to form a heat dissipation surface, and the other side of each of the L-shaped heat dissipation plates 134 is engaged with the limiting bar 132.

Specifically, by arranging the limit bars 132 in plurality side by side, it is advantageous to ensure the stability of the connection between the L-shaped heat dissipation plate 134 and the limit bars 132. In connection, only a limit groove is formed on the side corresponding to the L-shaped heat dissipation plate 134, and the limit groove is engaged with the limit bar 132.
