Heat sink for electromechanical device

The invention relates to the technical field of electromechanical devices, in particular to a heat sink for an electromechanical device. The technical problem to be solved by the invention is that theelectromechanical machine tool is only provided with heat dissipation holes for heat dissipation, a the heat dissipation effect is not obvious, and the internal temperature of the electromechanical machine tool is easily increased, which causes the internal circuit wire of the numerical control machine tool to be blown due to the temperature rise. In order to solve the above technical problem, the invention provides a heat sink for an electromechanical device, which comprises a box body; one side of the box body is fixedly connected to a machine body; an inner wall of the bottom of the machine body is fixedly connected to an electromechanical driving body; the inner wall of the bottom of the box body is fixedly connected to a water tank body; the water tank body is fixedly connected to aninput end of a refrigerating machine body through a connecting pipe. The heat sink of the electromechanical device can enlarge the water flow dissipating efficiency through a wet curtain, and can convert the heat from one side of the wet curtain into the cold air to be discharged into the interior of the machine body, and can achieve the daily heat dissipation effect required by the electromechanical machine tool.
