Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal cutting equipment, and particularly relates to a laser cutting equipment for water-cooled plate processing with efficient cooling. BACKGROUND

[0002] The water-cooled plate is a key component of the automobile cooling system, and is mainly used for efficient heat dissipation and temperature control, and is widely applied in new energy vehicles, and is suitable for precise temperature control of high-power devices such as power batteries and motors in new energy vehicles.

[0003] The brazed water-cooled plate is usually composed of two metal plates (such as aluminum plates), one of which is formed into an internal flow channel structure through stamping processing, and the other is a cover plate, which is sealed and connected through a brazing process.

[0004] In the processing of aluminum plate raw materials of the brazed water-cooled plate, cutting is required through laser cutting to ensure the processing precision of the plate. In the process of continuous cutting of the plate by the laser cutting equipment, a large amount of heat is generated by the laser cutting head, so that the working temperature of the laser is maintained below 45 DEG C, so as to avoid output power fluctuation or optical element damage, and at the same time avoid reducing the power after exceeding 45 DEG C. Therefore, the laser cutting machine needs to be cooled in time to ensure the cutting quality.

[0005] The existing laser cutting head is cooled through an externally arranged cooling pipeline, and heat exchange is realized by using a cooling medium in the cooling pipeline. However, the cooling system can only adjust the cooling capacity by adjusting the flow of the cooling medium, and cannot quickly adjust the cooling capacity to respond to the rapid temperature rise and other emergency states of the laser cutting head, resulting in that the laser cutting head is not cooled in time.
