The thickness of the heat dissipation ring 23 is equal to the thickness of the heat dissipation fin 11.
The difference between the inner diameter of the heat dissipating ring 23 and the outer diameter of the print head 1 is greater than twice the thickness of the heat dissipating ring 23 and less than four times the thickness of the heat dissipating ring.
The difference between the outer diameter of the heat sink 11 and the diameter of the inner wall of the heat dissipation chamber 22 is greater than twice the thickness of the heat sink 11 and less than four times the thickness of the heat sink.
The connecting hole 21 is connected with a welding groove 24, the printing head 1 is arranged in the connecting hole 21 by welding, and a welding seam 5 between the printing head 1 and the connecting hole 21 is arranged in the welding groove 24.
The heat dissipation shell 2 comprises a left half side and a right half side, and the left half side and the right half side are connected into a whole through welding; and the left half side and the right half side are respectively provided with a liquid inlet pipe 3 in a sealing way.
The feed liquor pipe 3 is located the outer end of heat dissipation shell is provided with threaded connection end 32, connection end 32 is connected with sealed step 31, connection end 32 is used for connecting external water pipe, sealed step 31 is right the tip of external water pipe is sealed.
The drain pipe 4 is provided with a step ring 41, the step ring 41 is hermetically installed on the heat dissipation shell 2, and the end part of the drain pipe 4 is provided with a quick-connection plug 42.
The temperature detector 13 of the device detects the temperature of the head 11, and if the temperature exceeds a target value, the temperature needs to be reduced. The reason why the temperature detector is provided in the head 11 is that the temperature detector is closest to the ejection hole and can most represent the actual temperature of the material to be subjected to the printing operation.
The heat sink 11 of the present device is directly connected to the outer wall of the print head 1, and therefore can directly conduct heat from the print head 1. The heat dissipation ring 23 of the device is matched with the heat dissipation fins 11 to be arranged at intervals, so that a flow channel is formed in the heat dissipation cavity 22, cooling water flowing inside can fully dissipate heat of the heat dissipation fins, and a large amount of heat can be taken away.
In order to obtain a good heat dissipation effect, the size of the flow channel needs to be controlled. In addition, cost considerations are also required. Therefore, the device is arranged such that the gap between the heat dissipating ring 23 and the upper and lower portions of the heat dissipating fin 11 is the thickness of the heat dissipating fin 11. The difference between the inner diameter of the heat dissipating ring 23 and the outer diameter of the print head 1 is greater than twice the thickness of the heat dissipating ring 23 and less than four times the thickness of the heat dissipating ring. The difference between the outer diameter of the heat sink 11 and the diameter of the inner wall of the heat dissipation chamber 22 is greater than twice the thickness of the heat sink 11 and less than four times the thickness of the heat sink. This arrangement enables the cooling water to sufficiently exchange heat with the fins 11,
this device can cool down printer head: the temperature of the print head is monitored by the temperature detector 13, and if the temperature is high, the temperature reduction operation is started. The two inlet pipes 3 are fed with cooling water which enters the heat dissipation chamber 22 and exchanges heat with the fins 11, thereby taking away heat therefrom. Finally, the cooling water leaves from the upper outlet pipe 4, carrying away a large amount of heat.
If the temperature detector 13 detects that the temperature of the head 12 meets the requirement after heat dissipation, the temperature of the print head 1 is not reduced.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
