Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, in particular to a cooling device for producing optical modules. Background Art

[0002] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving. Simply put, the function of the optical module is to convert electrical signals into optical signals at the transmitting end. After being transmitted through optical fibers, the receiving end converts the optical signals into electrical signals.

[0003] Application No. 202121370431.9 discloses a cooling device for optical module production testing, specifically related to the field of optical modules, including a box body, the inner cavity of the box body is provided with a cooling mechanism, the cooling mechanism includes an air compressor, the air outlet of the air compressor is connected to an air outlet pipe, the end of the air outlet pipe away from the air compressor is connected to a vortex tube, the cold air output end of the vortex tube is connected to an air guide tube, the hot air output end of the vortex tube is connected to an L-shaped tube, and the end of the L-shaped tube away from the vortex tube passes through the front side of the box body. The utility model is provided with a cooling mechanism to transport cold air in multiple directions, and at the same time, the speed of cooling is accelerated by blades, so that multi-directional cooling can be achieved, the speed of cooling is accelerated, the energy consumption is small, the cost is low, the cooling effect is obvious, and the loss of cold air during transportation is reduced.

[0004] The above scheme has some shortcomings during use. The air compressor is used to compress air for cooling to remove the heat from the surface of the optical module, so that the temperature of the optical module is reduced. However, in the process of compressing air, the air compressor will generate noise due to the up and down movement of the piston. In addition, due to the movement and collision of the internal parts of the compressor, vibration will also be generated. These noises and vibrations will cause the radiator surface of the optical module to vibrate and resonate, thereby affecting the heat dissipation effect. For this reason, we propose an optical module production cooling device to solve the above problems. Utility Model Content
