Abstract
The utility model discloses a water cooling heat exchanger for a solid laser with large power. The utility model comprises a heat exchanger with cavities of double layers and an inlet and an outlet for cooling and cooled medium thereof. Especially, both ends of the inner cavity body of the heat exchanger are inlet for cooling water and outlet for cooling water and the surface is provided with a spiral radiating fin. The outer cavity body of the heat exchanger is sheathed and packed outside the spiral radiating fin and both ends are connected with an inlet for cooled liquid and outlet for cooled liquid. The utility model obtains high heat exchanger effectiveness with a smaller volume and has the advantages of compact structure and easy modularization and assembly so as to be suitable for being used at heat-exchange situations with different grades.
Description
The utility model relates to a kind of great-power solid laser water-cooled heat-exchange device.
Great-power solid laser has purposes more widely in welding industry and some scientific research field, in its course of work owing to be subjected to the influence of conversion efficiency, most of electric flux of input is converted into heat energy and discharges, these heat energy are as can not in time taking away, the efficient of laser will greatly be influenced, when serious even can damage laser, vitals for high power laser so heat exchanger is absolutely necessary.The a large amount of bend pipe of the general employing of the heat exchanger of existing great-power solid laser is immersed in and carries out heat exchange in the mobile running water, the two ends of its bend pipe are respectively going into, exporting of the liquid that is cooled, the container of dress running water is circumscribed with running water pipe and sewer pipe, as using in the laser welding industry at present.But the heat radiation contact area of this heat exchanger is little, needs do bend pipe very longly for improving heat exchanger effectiveness, caused one be many with material, volume is big, the 2nd, strengthened the use amount of the liquid that is cooled, thereby made the overall price of Optical Maser System improve many.
The purpose of this utility model provides a kind of heat exchanger effectiveness height, great-power solid laser water-cooled heat-exchange device that volume is little.
For achieving the above object, the utility model comprise double-layer cavity heat exchanger and on cooling go into, export with the medium that is cooled, the two ends of the inner chamber body of described heat exchanger are cooling water inlet, coolant outlet, its outer surface is the spiral heat dissipation sheet, the outer chamber cover of described heat exchanger is enclosed in outside the spiral heat dissipation sheet, and its two ends are connected with the liquid inlet that is cooled, the liquid that is cooled outlet.
As further improvement of the utility model, described inner chamber body, outer chamber are tubular body; Described spiral heat dissipation sheet is the multiple tracks helicoid; Per pass spacing in the described multiple tracks helicoid is 1～3 millimeter; The described liquid inlet that is cooled, the opposing two ends that are arranged at outer chamber of the liquid that is cooled outlet.
After adopting such structure, owing to cooling water rapid percolation from inner chamber is crossed, so the whole cavity that comprises the spiral heat dissipation sheet is maintained at and the essentially identical temperature of cooling water.Again owing to the liquid that is cooled in outer chamber can only flow through between the spiral heat dissipation sheet, and the spiral heat dissipation sheet is multiple tracks and mutual spacing and less, so the feasible liquid that is cooled is divided into the multiple flow kinetoplast by force, relative contact thereby unit volume is cooled between liquid and the cooling water increases greatly, heat exchanger effectiveness is greatly improved, has only realized just reaching the purpose of high heat exchanger effectiveness with smaller volume.Because this apparatus structure compactness, be convenient to the modularization assembling again, thus its many can be gone here and there or are connected in parallel, to adapt to the heat exchange occasion use of different brackets.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of basic structure schematic diagram of the present utility model.
As shown in Figure 1, inner chamber body 5 is a straight pipe, and its two ends are respectively cooling water inlet 1 and coolant outlet 6, outer surface are multiple tracks spiral heat dissipation sheet 4.The two ends that cover is enclosed in the tubulose outer chamber 3 outside the multiple tracks spiral heat dissipation sheet 4 have opposing and the liquid inlet 2 that is cooled, the liquid that is cooled outlet 9 that establish.
During use, only needing cooling water 7 and circulation be cooled, liquid 8 inserts of the present utility modelly correspondingly to go into, outlet gets final product.If one can not be satisfied the cooling requirement, many serial or parallel connections can be coupled together use.
