Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 As shown, an instrument cooling device includes a fixing frame 1. A water tank 2 is fixed to the bottom of the fixing frame 1. A position adjustment structure 3 is movably connected inside the fixing frame 1. The middle of the top of the water tank 2 is fixed with an instrument placement table 4. An air pump 5 is fixed to the front side of the water tank 2, and a ventilation pipe 6 is connected to the rear side of the air pump 5. Through holes 7 are formed on the top surface of the instrument placement table 4. Mounting frames 8 are fixed to the left and right sides above the position adjustment structure 3, and a cooling plate 9 is fixed to one side of the mounting frame 8. A two-way water pump 10 is fixed to the back of the water tank 2, and the two-way water pump 10 is communicated with the water tank 2. A water pipe 11 is connected to the front side of the two-way water pump 10.

[0023] The position - adjusting structure 3 includes a motor 31, a threaded rod 32 and a moving table 33. The motor 31 is fixed on the left side of the fixed frame 1. The threaded rod 32 is rotatably connected inside the fixed frame 1, and the output shaft of the motor 31 penetrates into the inside of the fixed frame 1 and is fixedly connected to the left end of the threaded rod 32. The moving table 33 is slidably connected to the left and right sides inside the fixed frame 1. The thread directions on the left and right sides of the surface of the threaded rod 32 are oppositely arranged, and the threaded rod 32 penetrates through the moving table 33 and is threadedly connected to the moving tables 33 on both sides. The bottom of the mounting frame 8 is bolted to the top of the moving table 33. Guide bars 12 are fixed on both the front and rear sides of the top of the fixed frame 1. Guide blocks 13 are fixed on both the front and rear sides of the bottom of the moving table 33, and the guide bars 12 penetrate through the guide blocks 13 and are slidably connected to the inner walls of the guide blocks 13. When the motor 31 is turned on, the output shaft of the motor 31 drives the threaded rod 32 to rotate, and the moving tables 33 on both sides of the surface of the threaded rod 32 move towards each other or in opposite directions, thereby adjusting the position of the cooling plate 9 according to the size of the instrument. When the moving table 33 moves, the guide block 13 also slides above the guide bar 12, thereby guiding the moving table 33 and improving the stability of the moving table 33 during movement.

[0024] The inside of the instrument placement table 4 is hollow, and the end of the ventilation pipe 6 far from the air pump 5 penetrates into the inside of the instrument placement table 4 and is fixedly connected to the instrument placement table 4. The number of through - holes 7 is several, and the through - holes 7 are evenly distributed on the surface of the top of the instrument placement table 4. When the instrument is placed above the instrument placement table 4, by turning on the air pump 5, the air pump 5 inflates the inside of the instrument placement table 4 through the ventilation pipe 6, and then the air blows onto the instrument above through the through - holes 7, performing air - cooling on the surface of the instrument from bottom to top.

[0025] The material of the cooling plate 9 is copper - aluminum alloy, and fans 15 are fixed on the surfaces of the opposite sides of the cooling plate 9. A number of anti - slip strips 14 are bonded to the surfaces of the opposite sides of the cooling plate 9, and the anti - slip strips 14 are thermally conductive silicone sheets. When the surface of the cooling plate 9 contacts the instrument, the anti - slip strips 14 can not only dissipate heat from the instrument but also improve the fixing effect on the instrument. Through the setting of the fans 15, when water enters the inside of the cooling plate 9, the fans 15 will also discharge the heat on the surface of the cooling plate 9 to one side, further improving the heat dissipation effect on the instrument.

[0026] Heat - conducting sheets 16 are fixed on both the left and right sides of the water tank 2. The number of heat - conducting sheets 16 is several, and one side of the heat - conducting sheets 16 penetrates through the water tank 2 and extends into the inside of the water tank 2. When the water inside the cooling plate 9 flows back into the inside of the water tank 2 again, the heat - conducting sheets 16 can dissipate the heat inside the water tank 2 to the outside, thereby cooling the water inside the water tank 2 for subsequent heat - dissipation and cooling treatment of the instrument above.

[0027] The water pipe 11 is integrally arranged in a T shape, and both the left and right ends above the water pipe 11 are communicated with the cooling plate 9. The upper half of the water pipe 11 is a telescopic hose. When the cooling plate 9 moves back and forth, the water pipe 11 can also be stretched or contracted to inject cooling water into the inside of the cooling plate 9 to cool the instrument.

[0028] Working principle: When it is necessary to fix the instrument and this device, the staff takes out the instrument and places it on the top of the instrument placement table 4. Then the staff turns on the left motor 31, which makes the threaded rod 32 rotate, and the moving platforms 33 on the left and right move towards each other. According to the size of the instrument, the position of the cooling plate 9 is adjusted so that the cooling plate 9 fits on both sides of the instrument and clamps and fixes the instrument, thus completing the installation operation. When the instrument is running, the staff can turn on the air pump 5 and the two-way water pump 10 at the back. The air pump 5 pumps air into the inside of the instrument placement table 4, and the air blows out from the through holes 7 to cool the surface of the upper instrument by air cooling. The two-way water pump 10 pumps the water in the water tank 2 into the inside of the water pipe 11, and the water enters the inside of the cooling plate 9. The heat on the surface of the instrument is transferred to the surface of the cooling plate 9, and then the instrument is cooled by water. Then the two-way water pump 10 pumps the water in the cooling plate 9 back into the inside of the water tank 2 and pumps the water in the water tank 2 into the inside of the cooling plate 9 again. The fan 15 on one side of the surface of the cooling plate 9 is also turned on to further cool the surface of the instrument, so that the temperature of the instrument is maintained at a suitable working temperature.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
