Problems solved by technology
[0002] Based on the liquid-cooled modularized integrated rack, in the current structural technical scheme, the liquid-cooled plate module of the rack is generally welded with traditional aluminum alloy materials, and it is difficult to carry out anti-corrosion treatment for the internal flow channel, and more depends on the strength of the material itself. Corrosion resistance to ensure the protective ability of the cold plate, at the same time, the flux brought during the welding process is more likely to be corroded by the coolant
On the one hand, the corrosion products of the cold plate material and flux are easy to form adhesion and deposit in the flow channel of the rack, reducing the liquid flow and heat dissipation capacity of the cold plate. On the other hand, long-term corrosion will cause serious consequences of cold plate leakage
[0003] In the current structural technical scheme, the method of sealing the flow channel between the liquid cooling components of the rack is a self-sealing liquid flow joint or a radial sealing method directly using an O-ring seal. This sealing method has a positive effect on the processing of related structures. High precision requirements, easy to cause leakage due to scratches of the sealing ring during installation and operation
Chinese Patent Publication No. CN104244682A (published on December 24, 2014) discloses a liquid-cooled sub-box suitable for radar antennas. Corrosion has serious consequences
This method of liquid cooling subracks is only for the liquid cooling method of single-layer racks, and does not involve the method of splitting and converging liquid cooling of multi-layer racks

The invention provides a corrosion-resistant modular integrated frame and aims to provide a modular integrated frame, wherein the modular integrated frame is reliable in sealing performance and resistant to the corrosion of various liquid cooling working media, and enables the shunting and the confluence of multilayer liquid-cooling board modules. According to the technical scheme of the invention, at least one side of each liquid-cooling board module (1) is provided with a module installation radiating groove. A titanium alloy seamless metal tube that is pre-bent to be molded in the U shape is embedded inside the substrate of each liquid-cooling board module, and the two ends of the seamless metal tube are in flush with the end surface of a liquid-cooling board to form a coolant influx port and a coolant outflux port of the liquid-cooling board. The coolant influx port and the coolant outflux port of the liquid-cooling board module are respectively communicated with two external connection branch confluence tubes (2) fixed on the side plates of the main body of the frame so as to form a shunting pathway and a confluence pathway among liquid-cooling board modules. The two branch confluence tubes are respectively led out to be connected with an external liquid-cooling source external interface and a self-sealing liquid flow joint (6) arranged on the external interface. According to the technical scheme of the invention, the sealing performance and the reliability of the flow channel are improved.
Description
technical field [0001] The invention relates to a modularized comprehensive rack, in particular to a corrosion-resistant multi-layer modularized comprehensive rack which adopts a liquid cooling method to realize conduction and heat dissipation of on-site replaceable modules. Background technique [0002] Based on the liquid-cooled modularized integrated rack, in the current structural technical scheme, the liquid-cooled plate module of the rack is generally welded with traditional aluminum alloy materials, and it is difficult to carry out anti-corrosion treatment for the internal flow channel, and more depends on the strength of the material itself. Corrosion resistance is used to ensure the protective ability of the cold plate. At the same time, the flux brought during the welding process is more likely to be corroded by the coolant. On the one hand, the corrosion products of the cold plate material and flux are easy to form adhesions and deposit in the flow channel of the ...
