Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.Laser crystal support as shown in Figure 1, comprise rectangular base 1, base 1 is provided with crystal tray 2, crystal tray 2 upper surface is horizontally disposed with can the low groove 3 of holding portion crystal, upper surface is removably connected with crystal fixed block 4 with crystal tray 2, this crystal fixed block 4 covers above low groove 3, crystal fixed block 4 with the face that crystal tray 2 contacts is provided with the upper groove 5 relative with low groove 3, described low groove 3 and upper groove 5 coordinate formation one to hold the installing hole 6 of laser crystal, and the hole wall of described installing hole 6 is provided with some grooves 7.
The hole wall of installing hole 6 is provided with some after the axially extended groove 7 of installing hole 6, when heat-conducting layer expanded by heating, part heat-conducting layer can be squeezed in groove 7, alleviate the pressure of heat-conducting layer to laser crystal with this, thus realize the function of the heat-conducting layer attrition crushing preventing laser crystal to be inflated.
Described groove 7 axially extends along installing hole 6.
The bearing of trend of groove 7 and the axial consistent of installing hole 6, facilitate the installation of laser crystal.
The upper surface of described crystal tray 2 is inclined plane, and the longitudinal section of described low groove 3 is V-arrangement, and two cell wall angles of low groove 3 are 90 degree; Correspondingly, the longitudinal section of described upper groove 5 is also V-arrangement, two cell wall angles are 90 degree, upper and lower groove 5,3 cooperation formation longitudinal section is the installing hole 6 of rectangle, the bottom of described upper groove 5 and low groove 3 is respectively arranged with one along the axially extended groove 7 of installing hole 6, described crystal tray 2 upper surface is provided with some screwed holes 8, on crystal fixed block 4, correspondence is provided with some bolt fixing hole 9, the diameter of described bolt fixing hole 9 is slightly larger than the diameter of screwed hole 8, and described crystal fixed block 4 is fixed on crystal tray 2 by bolt 10.
Said structure is not when bolt 10 is tightened, because bolt fixing hole 9 diameter is slightly larger than bolt 10 diameter, therefore crystal fixed block 4 can do appropriate slippage relative to crystal tray 2 along the face contacted with each other, thus the fine setting realized installing hole 6, to meet the clamping to the slightly discrepant laser crystal of size, the scope of application of expansion of laser light crystal cartridge.
As shown in Figure 2, in described crystal tray 2 and crystal fixed block 4, be provided with the cooling duct 11 communicated, described base 1 be provided with the cooling duct entrance 12 that is connected with two ends, cooling duct 11 respectively and cooling duct exports 13.
Because heat is conducted to crystal tray 2 and crystal fixed block 4 by heat-conducting layer by laser crystal, therefore after cooling duct is set, recirculated water is utilized to cool crystal tray 2 and crystal fixed block 4, just the working temperature of laser crystal can effectively be reduced, extend the useful life of laser crystal, guarantee the work safety of whole laser generating system.
As shown in Figure 2 and Figure 3, described cooling duct 11 forms mutually corresponding passway 14 respectively on the face that crystal tray 2 and crystal fixed block 4 be combined with each other, passway 14 surrounding be positioned on crystal tray 2 and/or crystal fixed block 4 is provided with recessed sealing ring positioning pit 15, is provided with sealing ring 16 in the sealing ring positioning pit 15 on described crystal tray 2 or crystal fixed block 4.
Can effectively prevent cooling fluid from the contact-making surface of crystal tray 2 and crystal fixed block 4, seepage occurring after sealing ring 16 is set, in passway 14 surrounding, recessed sealing ring positioning pit 15 is set, can the effective position of fixed seal ring 16 on the contact-making surface of crystal tray 2 and crystal fixed block 4.
As shown in Figure 4, cooling duct entrance 12 and cooling duct outlet 13 are arranged on the facade of base 1, and the quantity of cooling duct entrance 12 and cooling duct outlet 13 is respectively two, two cooling duct entrances 12 are arranged on two adjacent facades respectively, and two cooling duct outlets 13 are arranged on two other adjacent facade respectively.
Two pairs of cooling duct entrances 12 and cooling duct outlet 13 and be separately positioned on different facades are set, are conducive to the flexibility when mounted of laser crystal support.Such as when laser crystal support installing is when narrow space, its both sides are stopped cannot install cooling water pipe by other electronic components, so can select that cooling water pipe is not exported 13 by the cooling duct entrance 12 that other electronic components stop with cooling duct with other both sides to be connected, for the cooling duct entrance 12 and cooling duct outlet 13 that prevent from not connecting cooling water pipe leak, rubber stopper can be used to be blocked.
The course of work of the present utility model is: as shown in Figure 1, is first given away by bolt 10, and then by the laser crystal that matches with installing hole 6, (longitudinal section of installing hole 6 is as shown in Figure 1 rectangle, then laser crystal longitudinal section is also rectangle.) surrounding superscribes heat-conducting layer, and insert in installing hole 6 from one end of installing hole 6, next 10 are tighted a bolt, laser crystal is fixed by crystal tray 2 and crystal fixed block 4, just operating state can be entered, when laser is irradiated on laser crystal, laser crystal is heated, and by heat-conducting layer to crystal tray 2 and crystal fixed block 4 transferring heat, heat-conducting layer is expanded by heating in the process of transferring heat, the heat-conducting layer of demi-inflation is clamp-oned in groove 7 by pressure, to reduce heat-conducting layer because of the pressure to laser crystal brought that expands, cooling duct 11 internal circulation flow cooling fluid, reduce the temperature of crystal tray 2 and crystal fixed block 4.
