Deep Drilling Cold Plate
The simple straight channel makes cold plate processing convenient.
Which is the choice for your design with small demand and cost advantage.
Deep Drilling Cold Plate
Process introduction:
Several direct current channels are processed on the aluminum substrate by deep hole drilling technology, and the side drilling or end surface machining methods are used to connect the direct current channels to form a complete flow channel. Except for the inlet and outlet, other openings can be sealed by friction stir welding, argon arc welding, laser welding, etc., and then processed into a liquid cooling plate after mechanical processing and surface treatment.
Design Reference:
Common tool diameters for deep hole drilling of liquid cooling plates:
Φ5mm, Φ6mm, Φ7mm, Φ8mm, Φ9mm, Φ10mm, Φ11mm, Φ12mm, Φ13mm, Φ14mm, Φ15mm, Φ16mm, Φ17mm, Φ18mm, Φ20mm
Deep hole drilling channel depth can be up to 1600mm
Application Status:
The deep hole drilling liquid cooling plate has a simple flow channel structure that is easy to process, has good product stability, can be installed on both sides of the liquid cooling plate for heat dissipation, and has a large flow channel depth, which is very suitable for making long flow channel liquid cooling plates; at the same time, due to the processing characteristics, the flow channel is a simple straight structure, and the design flexibility is relatively low.
It is particularly important to improve the radiator cutting and processing efficiency and shorten the production cycle.
Deep drilling process can meet the shorten production delivery very well,It is easy and convenient for operating.
FSW machining the insert block for the deep drilling cold plate.
Deep drilling the straight channels + insert block , After FSW process and CNC machining, To be a cold plate!
Or use laser welding plugging method, laser welding has the characteristics of high processing efficiency, smooth weld, low welding follow-up workload, stable penetration, and can achieve precision welding. How about the firmness and airtightness of laser welding? After the workpiece is welded, airtightness test and pressure resistance test are carried out. Generally, there is no problem in withstanding pressure of about 2Mpa.
