[0025] The utility model is further described below in conjunction with the accompanying drawings and implementation methods. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the laser packaging fixture provided by the utility model from a first viewing angle; Figure 2 A second perspective structural diagram of a preferred embodiment of the laser packaging fixture provided by the utility model Figure 3 A schematic diagram of a detachable connection structure of heat dissipation fins and coolant pipes; Figure 4 A schematic diagram of a detachable installation structure of heat dissipation fins and coolant pipes; Figure 5 A schematic diagram of another detachable connection structure of the heat dissipation fins and the coolant pipe; Figure 6 for Figure 5 An enlarged schematic diagram of part A is shown.
[0026] The laser packaging fixture includes: a fixed operating table 1, a movable operating table 2, a heat dissipation fin 3 and a coolant pipe 4; the fixed operating table 1 and the movable operating table 2 form a fixture, and a plurality of heat dissipation fins 3 are fixedly connected to the bottom of the fixed operating table 1 to increase the heat dissipation area at the bottom of the fixed operating table 1; the plurality of heat dissipation fins 3 are fixedly connected to the coolant pipe 4 and the heat dissipation fins 3 penetrate the coolant pipe 4 to penetrate into the coolant pipe 4, and the heat dissipation fins 3 extend to the bottom of the coolant pipe 4. The coolant pipe 4 is provided with a liquid inlet pipe 19 and a liquid outlet pipe 20 for the coolant to enter and flow out respectively. The coolant flows through the coolant pipe 4, and the heat dissipation fins 3 are partially immersed in the coolant, and the heat on the heat dissipation fins 3 is taken away by the coolant to increase the cooling rate. The heat dissipation fins 3 extend to the two sides of the fixed operating table 1 and are clamped on the two sides. The fixed operating table 1 can dissipate heat from the bottom and two sides at the same time through the heat dissipation fins 3, and further improve the heat dissipation efficiency and rate by increasing the heat dissipation area. An observation window 5 is provided on the coolant pipe 4, and a scale line 6 is provided on the observation window 5 to display the depth of the heat dissipation fin 3 immersed in the coolant. The depth of the heat dissipation fin 3 immersed in the coolant is proportional to the heat exchange area between the heat dissipation fin 3 and the coolant, so the heat exchange rate between the heat dissipation fin 3 and the coolant can be adjusted by adjusting the depth of the heat dissipation fin 3 immersed in the coolant, so as to further achieve accurate control of the cooling rate and meet the aging requirements. The observation window 5 can be made of organic glass. Preferably, there is a pair of observation windows 5, and a pair of observation windows 5 are respectively arranged on two opposite sides of the coolant pipe 4. When observing the water level from one side of the observation window 5, the light transmitted through the other observation window 5 can realize easy observation of the water level, which is more convenient for accurately and clearly reading the corresponding scale line 6 of the liquid level.
[0027] The heat dissipation fin 3 is provided with a plurality of through holes 7 on the sheet portion of the coolant tube 4. The shape of the through hole 7 is not limited, and a circular through hole 7 is taken as an example. The circular through hole 7 can increase the contact area between the heat dissipation fin 3 and the coolant to improve the heat dissipation efficiency of the coolant; at the same time, the circular through hole 7 is also the turbulence generating point of the coolant to increase the uniform distribution effect of the heat in the coolant, which is also conducive to improving the heat dissipation efficiency. Preferably, the plurality of through holes 7 are evenly distributed on the heat dissipation fin 3, which is conducive to ensuring uniform heat dissipation on the heat dissipation fin 3 and uniform distribution of heat in the coolant.
[0028] Specifically, the heat sink 3 is detachably fixedly connected to the coolant pipe 4. When scale accumulates on the heat sink 3, the heat sink 3 can be removed from the coolant pipe 4 for cleaning to avoid excessive thermal resistance caused by the scale layer and reduce the heat dissipation rate.
[0029] The coolant pipe 4 is provided with a socket 8 for inserting the heat sink fin 3, and the heat sink fin 3 is provided with a first threaded through hole 11; a connecting plate 9 is fixedly connected to the coolant pipe 4, and a second threaded through hole 12 is provided on the connecting plate 9; when the heat sink fin 3 is inserted into the socket 8, the bolt 10 is inserted into the first threaded through hole 11 and the second threaded through hole 12 in sequence, and the heat sink fin 3 is detachably fixedly connected to the connecting plate 9 by the bolt 10.
[0030] The cooling liquid pipe 4 is provided with an insertion hole 8 for inserting the heat dissipation fin 3. A pair of thinner side surfaces on the heat dissipation fin 3 are respectively provided with a V-shaped self-locking groove 13.
[0031] A pair of guide sleeves 14 are fixedly connected to the coolant pipe 4, and each guide sleeve 14 is slidably sleeved on a connecting rod 15; a V-shaped self-locking block 16 is fixedly connected to one end of the connecting rod 15 facing the heat sink 3. The other end of the connecting rod 15 slides through the guide sleeve 14 and is fixedly connected to the baffle 17. A compression spring 18 is sleeved on the connecting rod 15, one end of the compression spring 18 abuts on the V-shaped self-locking block 16, and the other end of the compression spring 18 abuts on the guide sleeve 14. When the heat sink 3 plug hole 8 is inserted into the plug hole 8, the pair of V-shaped self-locking blocks 16 will automatically snap into the pair of V-shaped self-locking grooves 13 under the action of the compression spring 18, thereby fixing the heat sink 3 on the coolant pipe 4. When disassembling, it is only necessary to pull out the pair of V-shaped self-locking blocks 16 to both ends to pull out the pair of V-shaped self-locking blocks 16 from the V-shaped self-locking grooves 13, and the heat sink 3 can be smoothly pulled out from the coolant pipe 4. The baffle 17 can prevent the connecting rod 15 from slipping out of the guide sleeve 14 .
[0032] The working principle of the laser packaging fixture provided by the utility model is as follows:
[0033] The utility model provides a laser packaging fixture, wherein a heat dissipation fin 3 is partially exposed to the air, and this part improves the heat dissipation rate by increasing the heat dissipation area of the bottom of the fixed operating table 1; the heat dissipation fin 3 is partially immersed in liquid cooling, and the heat exchange rate between the heat dissipation fin 3 and the coolant is faster than that of the air, so this part simultaneously improves the heat dissipation rate by increasing the heat dissipation area and the heat exchange rate of the bottom of the fixed operating table 1.
