Description

Gas or solid state laser heat abstractor

Technical field

The present invention relates to a kind of gas or Solid State Laser heat abstractor, belong to the photoelectron technology field.

Background technology

Gas or solid state laser are lasers at present very commonly used, and well-known is that the efficient of laser is all very low, and the direct result that causes is not only to have wasted lot of energy; And brought great amount of heat for laser itself; If these heats can not in time shed, can bring fatal harm for laser, so present laser generally all is provided with various heat abstractors; Such as water-cooled, air-cooled or the like.But the applicant finds; These present heat abstractor ubiquity radiating efficiencys are low; Be exactly that heat abstractor is very big, or be exactly that radiating effect is bad, the present invention proposes to this problem; A kind of heat abstractor of high efficiency small size is provided, and has realized and the fine compatibility of laser itself.

Summary of the invention

The invention provides a kind of solid or gas laser heat abstractor; Comprise: solid laser rod or Gas LASER Tube (1); Arc cavity (2); Radiating fin (3); Heat-conductive bonding agent (4), urceolus (5), and fluid passage (6); Said solid laser rod or Gas LASER Tube (1) are positioned at central authorities; Certain thickness heat-conductive bonding agent (4) be arranged on solid laser rod or Gas LASER Tube (1) around, said radiating fin (3) is made up of orthogonal heatsink transverse plate and vertical heating panel, said vertical heating panel is positioned on the center line of heatsink transverse plate; Form the radiating fin that the cross section is an inverted T-shape (3) therefrom; The thickness that said heat-conductive bonding agent (4) is had can cover the heatsink transverse plate of said radiating fin (3) when can radiating fin (3) and solid laser rod or Gas LASER Tube (1) being bonded together, said radiating fin (3) is provided with a plurality of with nonoverlapping mode round the circumference of solid laser rod or Gas LASER Tube, and wherein each all is that axis direction along solid laser rod or Gas LASER Tube (1) extends; And the vertical heating panel of said radiating fin (3) is provided with a plurality of through holes that penetrate said vertical heating panel; Described radiating fin (3) with the heatsink transverse plate of said radiating fin (3) carried out according to the bending curvature of solid laser rod or Gas LASER Tube (1) when solid laser rod or Gas LASER Tube (1) make up that crooked said heat-conductive bonding agent (4) is the center with the vertical heating panel of said radiating fin (3) so that the heatsink transverse plate of said radiating fin (3) engages with solid laser rod or Gas LASER Tube (1), thickness diminishes gradually in away from the process of vertical heating panel; Thereby between adjacent two radiating fins (3), form said arc cavity (2); Said urceolus (5) is sleeved on to engage to be had on the solid laser rod or Gas LASER Tube (1) of radiating fin (3), thereby at the inner a plurality of fluid passages (6) that form of urceolus, liquid entrance is reserved at the two ends of said urceolus (5).

Use above-mentioned heat abstractor can effectively improve the radiating efficiency of laser, thereby realize big radiating effect, can realize the laser low-power consumption, integrated demand with the heat abstractor of small volume low watt consumption.

Description of drawings

Accompanying drawing 1 is the cross-sectional view of laser heat abstractor of the present invention;

Accompanying drawing 2 is perspective views of the radiating fin in the laser heat abstractor among the present invention;

Accompanying drawing 3 is enlarged diagrams of the base section after being assembled on the heat abstractor of the radiating fin in the laser heat abstractor among the present invention.

In three above-mentioned figure, 1 expression solid laser rod or Gas LASER Tube, arc cavity between 2 expressions, two radiating fins; 3 expression radiating fins; 4 expressions are arranged on the heat-conductive bonding agent around solid laser rod or the Gas LASER Tube, 5 expression urceolus, the fluid passage between the 6 expression radiating fins.

Embodiment

To combine to describe device of the present invention on the basis of accompanying drawing in detail below; Accompanying drawing 1 shows the cross sectional representation of heat abstractor of the present invention; What wherein be positioned at central authorities is solid laser rod or Gas LASER Tube 1; Around solid laser rod or Gas LASER Tube, be provided with one deck and have certain thickness heat-conductive bonding agent 4; The thickness that this heat-conductive bonding agent had can cover the bottom of inverted T-shaped radiating fin 3 when the radiating fin 3 that with cross section is inverted T-shaped is bonded together with solid laser rod or Gas LASER Tube 1, the lateral part that also is about to T shape fin covers, and only the vertical part of T font is exposed to the outside; The radiating fin 3 of said cross section T font is by along laterally forming with vertically disposed two blocks of heating panels vertically and each other; The heating panel of said vertical direction is positioned on the center line of heatsink transverse plate, and forming the cross section therefrom is the radiating fin 3 of inverted T-shape, and this radiating fin 3 is provided with a plurality of round the circumference of solid laser rod or Gas LASER Tube with nonoverlapping mode; Wherein each all is the axis direction extensions along solid laser rod or Gas LASER Tube; And include the vertical part 32 of horizontal component 31 and T font at T font radiating fin 3, wherein the vertical part 32 of T font is provided with a plurality of through holes 33 that penetrate said vertical heating panel, as attaches shown in Fig. 1 and 2.Radiating fin 3 wherein with the heatsink transverse sheet of radiating fin 3 is carried out bending so that the heatsink transverse plate of radiating fin 3 better engages with solid laser rod or Gas LASER Tube according to the bending curvature of solid laser rod or Gas LASER Tube when solid laser rod or Gas LASER Tube engage; And heat-conductive bonding agent wherein is the center at the vertical heating panel with radiating fin 3; Thickness diminishes gradually in away from the process of the vertically both sides extension of heating panel; Thereby between two adjacent radiating fins 3, form the cavity of arc; Shown in accompanying drawing 3, has only a cross sectional representation that is bonded with the radiating fin 3 of heat-conductive bonding agent 4 shown in the accompanying drawing 3.After having set radiating fin 3 and heat-conductive bonding agent, urceolus 5 is sleeved on joint to be had on the solid laser rod or Gas LASER Tube of radiating fin, and reserves liquid entrance at two ends, has promptly formed this heat abstractor.

Use the heat abstractor of above-mentioned setting can effectively improve radiating efficiency, thereby realize big radiating effect, solved the existing many disadvantages of heat abstractor of the prior art with the heat abstractor of small size.
