The laser member heat radiation device comprises a supporting seat, an installing plate and a plurality of pressing blocks. The top face of the supporting seat is provided with a pit. The inner side wall of the pit is provided with at least three grooves. Two first steel balls are respectively placed inside each groove. The two first steel balls are horizontally arranged side by side. The shape of the installing plate matches that of the pit. The side surface of the installing plate is provided with pins corresponding to the grooves. The installing plate is arranged inside the pit but is a certain distance away from the side walls and the bottom wall of the pit. Each pin is placed inside the corresponding groove and supported between the corresponding two first steel balls. The pressing blocks corresponding to the pins one by one respectively make the corresponding pins fixed on the top face of the supporting seat. The installing plate and the supporting seat achieve point contact through the first steel balls. The contact area is thus small. Therefore, the installing plate for installing a laser member achieves thermal isolation with external connection parts. The cooling efficiency of the laser member is thus increased.

Embodiment
Below in conjunction with specification drawings and specific embodiments the utility model is made detailed explanation.
As shown in Figure 1, the solid state laser that the utility model provides and Laser Devices heat abstractor thereof comprise supporting seat 1, mounting panel 2 and a plurality of briquetting 3.Mounting panel 2 is used for Laser Devices are installed, and the effect of supporting seat 1 is support mounting plate 2, and being connected of realization and solid state laser miscellaneous part, and the effect of briquetting 3 is that mounting panel 2 is fixed on the end face of supporting seat 1.
See also Fig. 2 again, have a pit 11 on the end face of supporting seat 1, the madial wall of pit 11 is provided with three grooves 12, and each groove 12 all communicates with the end face of supporting seat 1, and placing 13, two first steel balls of two first steel balls, 13 horizontal Tiles in each groove 12 respectively arranges.In the present embodiment, pit 11 is the rectangle pit, and three grooves 12 are separately positioned on three madial walls of pit 11.
See also Fig. 1 again, the profile of mounting panel 2 and pit 11 are suitable, and be provided with a fixed gap between the side of the side of mounting panel 2 and pit 11, also be provided with certain space between the bottom surface of mounting panel 2 and the pit 11, thereby guarantee that mounting panel 2 does not all contact with each inwall of pit 11.The side of mounting panel 2 is provided with the bearing pin 21 corresponding with groove 12.Mounting panel 2 is arranged in the pit 11, bearing pin 21 is placed in the corresponding groove and is supported between two first steel balls 13, gap between two first steel balls 13 that are arranged side by side is less than the diameter of bearing pin 21, the diameter of the diameter of bearing pin 21 and first steel ball 13 is similar, thereby guarantees that bearing pin 21 forms point and contacts respectively with between two first steel balls 13.
