Description

TECHNICAL FIELD

[0001] The utility model relates to a heat dissipation device technical field, specifically, relate to a kind of heat dissipation magnet device for metal liquid drop injection. BACKGROUND

[0002] The existing heat dissipation magnet is mainly divided into two ways of air cooling and liquid cooling. Liquid cooling has high efficiency, but occupies large space, and the winding of liquid cooling pipe can easily make the surface of the magnet irregular, which reduces the magnet adaptation degree. In order to ensure the flatness of the surface, the magnet can only be wrapped in the liquid cooling tank, and the tank body is composed of multiple parts. With the passage of time, the sealing ability of the tank body will decrease, which may cause liquid leakage and other situations, affecting the working environment nearby and causing circuit failure and other accidents. The air cooling device is too large and mostly blows air, which can easily cause the liquid droplets to deviate. For example, patent CN107240476A cools the magnet by winding a water cooling pipe, which makes the surface of the magnet uneven and makes it difficult to install. CN115346761A uses cooling liquid to wrap the magnet, but does not ensure that water and electricity are separated. The subsequent sealing ability may decrease, causing the circuit to fail due to water ingress. CN116313405A separates water and electricity to achieve the purpose of heat dissipation, but the internal structure is complex, the space utilization is low, and the cooling effect is not obvious in a small space. CN118896076A uses air cooling method, but the volume is too large and the structure is not compact enough, which is not suitable for small devices. In the existing structure for metal liquid drop injection, the temperature of the metal liquid drop is high, so the heat dissipation requirement of the magnet is high. However, the existing structure has the problems of poor adaptability, large vibration and air cooling device that can easily cause the liquid droplets to deviate. SUMMARY

[0003] The utility model discloses a kind of heat dissipation magnet devices for metal liquid drop injection, simple structure, convenient operation, to improve the problem mentioned above.

[0004] The utility model adopts the following scheme:

[0005] A kind of heat dissipation magnet device for metal liquid drop injection, comprising: nozzle body, magnet, heat sink, heat dissipation fan, wherein the magnet is arranged between the nozzle body and the heat sink, the heat dissipation fan is arranged on the side of the heat sink away from the magnet, and the heat dissipation fan is adapted to adopt the way of air suction to dissipate heat to the heat sink.

[0006] Further, the magnet and the heat sink are connected by flexible connection.

[0007] Further, the heat dissipation fan and the heat sink are connected by nano double-sided tape.

[0008] Further, the magnet and the heat sink are connected by using a heat-conducting silicone paste patch.

[0009] Further, the magnet is in a strip shape.

[0010] Further, the heat sink comprises closely arranged heat dissipation fins, and gaps are arranged between adjacent heat dissipation fins and face the heat dissipation fan.

[0011] Advantages:

[0012] The wind cooling technology is used in the scheme, which can effectively prevent the problem of water entering the surrounding circuit caused by liquid cooling; the magnet can be designed in a strip shape, which is better adapted to different working environments, has a complete plane for adhering to the nozzle, and ensures the magnetic field strength. The heat dissipation fan, the heat sink and the magnet are connected by using a soft connection, which can effectively filter the vibration of the fan, and the fan adopts a suction mode, which greatly reduces the influence of the wind on the nozzle and the metal liquid drops. The scheme has simple structure, convenient maintenance and low maintenance cost. BRIEF DESCRIPTION OF DRAWINGS
