Description

Technical Field

[0001] This utility model relates to the field of TEC temperature control integration technology, and in particular to a TEC temperature control integration device and a rapid heat dissipation structure for a QCL laser module. Background Technology

[0002] In many fields such as optical communication, laser processing, and scientific research, QCL (specific wavelength band depends on the application scenario, such as the O-band 1260-1360nm often involved in optical communication) laser modules play a crucial role. When a laser is working, its performance is extremely sensitive to temperature. Even a small temperature fluctuation can cause wavelength drift and unstable output power, thus affecting the operating accuracy and reliability of the entire system. For example, in high-precision optical communication systems, slight wavelength drift can cause signal crosstalk and reduce communication quality. TEC (thermal cooler) has become a common solution for temperature control of QCL laser modules due to its precise temperature control, rapid response, and ease of control. However, traditional TEC temperature control integrated devices are insufficient in terms of integration and temperature control accuracy, making it difficult to meet the current stringent requirements for miniaturization and high performance of laser modules. At the same time, lasers generate a lot of heat when working. If this heat cannot be dissipated in time, it will not only exacerbate the negative impact of temperature on laser performance but may also shorten the lifespan of the laser.

[0003] Existing rapid heat dissipation structures have difficulty dissipating heat from the bottom to the outside during prolonged use, which affects their lifespan.

[0004] To address this, a TEC temperature control integrated device and a rapid heat dissipation structure for QCL laser modules are proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a TEC temperature control integrated device and a rapid heat dissipation structure for QCL laser modules to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this utility model embodiment is implemented as follows: a rapid heat dissipation structure includes a heat dissipation mechanism, which includes: a mounting sleeve, a copper sheet disposed inside the mounting sleeve, a cold conductive plate disposed on one side of the copper sheet, a cooling chip disposed inside the mounting sleeve, an alloy plate disposed on one side of the mounting sleeve, an alloy heat dissipation column disposed on one side of the alloy plate, a mounting cylinder disposed on one side of the mounting sleeve, a fan disposed inside the mounting cylinder, and an air outlet plate disposed on one side of the mounting cylinder.

[0007] In some embodiments, the main body includes: a device body, a support leg disposed at the bottom of the device body, a base plate disposed at the bottom of the support leg, and reinforcing plates disposed on both sides of the top of the base plate.

[0008] In some embodiments, the outer wall of the device body is provided with a mating ring, and the four corners of the mating ring are provided with openings.

[0009] In some embodiments, a mating plate is provided on one side of the mating ring, threaded holes are provided at the four corners of the mating plate, a mounting plate is provided on one side of the mating plate, and a heat dissipation box is provided on one side of the mounting plate.

[0010] In some embodiments, a heat dissipation cylinder is provided on one side of the heat dissipation box, and a mounting groove is provided inside the heat dissipation cylinder, and a cooling fan is provided inside the mounting groove.

[0011] The present invention has the following advantages due to the adoption of the above technical solution:

[0012] 1. The QCL laser module's TEC temperature control integrated device and rapid heat dissipation structure achieve efficient heat dissipation through multi-layer synergy during use. Copper sheets and cold conductive plates form a high thermal conductivity path, quickly absorbing and conducting heat from the heat source. Combined with the active Peltier cooling effect of the cooling chip, a dual mechanism of "heat conduction + active cooling" is formed, precisely reducing the temperature of the core area. Alloy heat sinks, together with fans and exhaust plates, construct a three-dimensional air-heat exchange system, increasing the heat dissipation area and accelerating heat dissipation through forced convection, significantly improving heat dissipation efficiency.
