Antibacterial filter cartridge and ai server liquid cooling system including the same

Abstract

This invention proposes an antibacterial filter element suitable for filtering coolant in an AI server liquid cooling system, comprising an outer frame, a filter media layer, and a composite antibacterial layer. The outer frame includes a plurality of openings. The filter media layer is disposed within the outer frame, and the filter media layer forms multiple filtration channels with a folded structure. The composite antibacterial layer is disposed on one surface of the filter media layer, and the composite antibacterial layer comprises two or three materials selected from silver, copper, zinc, and titanium. This invention also proposes an AI server liquid cooling system, including a coolant circulation loop and the aforementioned antibacterial filter element. Therefore, this invention can inhibit microbial growth and extend system life.

Claims

1. An antibacterial filter element suitable for filtering coolant in an AI server liquid cooling system, comprising: an outer frame having a plurality of openings; a filter media layer disposed within the outer frame, the filter media layer forming multiple filtration channels in a folded structure; and a composite antibacterial layer disposed on one surface of the filter media layer, the composite antibacterial layer comprising two or three materials selected from silver, copper, zinc and titanium.

2. The antibacterial filter cartridge as described in claim 1, wherein, The filter media layer is made of stainless steel sintered felt, stainless steel sintered mesh, chain mesh, or edge knot mesh.

3. The antibacterial filter cartridge as described in claim 1, wherein, These openings are circular openings with a diameter of 6mm, and they cover one of the exterior surfaces of the exoskeleton.

4. The antibacterial filter cartridge as described in claim 1, wherein, The filter media layer is made of SS316L grade stainless steel, and the outer frame is made of SS304 grade stainless steel.

5. The antibacterial filter element as described in claim 1, wherein, The filter media layer has a 36-fold structure, with each fold being 7.5 mm high.

6. The antibacterial filter cartridge as described in claim 1, wherein, The composite antibacterial layer achieved a 5B adhesion rating in the ASTM D3359 adhesion test.

7. The antibacterial filter cartridge as described in claim 1, wherein, The filtration accuracy of this filter media layer is 25 μm.

8. An AI server liquid cooling system comprising: a coolant circulation loop containing coolant; and an antibacterial filter element as described in claim 1, disposed in the coolant circulation loop to filter impurities and inhibit microbial growth, thereby extending the lifespan of the liquid cooling system.
