Crypto compute blade

The circuit board.
The fluid partition.
The replaceable blade.

A proposed ColdBoard application for dense ASIC arrays, with a vertical circuit board inside a sealed, replaceable module and reusable surrounding infrastructure.

Full-length cutaway of an upright ASIC blade with transparent liquid covering and wetting the board components, a curved integrated handle and all fluid and electrical connections on its narrow rear end face
VERTICAL ASIC BLADE CONCEPT · Full-length cutaway with the broad side cover removed. Transparent blue shading shows liquid covering and wetting the board and components. Sweeping arrows indicate flow from the lower distribution channel up across the board to the upper collection channel. The narrow rear end face carries the lengthwise rounded-rectangle upper fluid port, central electrical connector and matching lower fluid port; a sculpted handle is integrated into the opposite end. Internal construction and connector geometry are illustrative. Download image.

INSIDE THE BLADE

The board participates
in the enclosure.

The double-sided circuit board stands vertically within the blade, supporting and connecting the ASICs while separating the fluid regions on its two faces. Dielectric coolant wets the electronics; thermal-core regions can also contribute to heat spreading and transfer.

Flow distribution must serve the full active area. The inlet manifold, collection path, perimeter seals and board geometry must be evaluated together, rather than inferred from the rendered image.

A MODULAR SYSTEM

Separate the compute generation
from its support infrastructure.

01

Compute blade

ASICs, a vertical circuit-bearing partition, fluid regions on both faces and a sealed module enclosure. A smoothly contoured handle forms part of the front case, supporting insertion and removal.

02

Rack interfaces

Low-profile rounded-rectangle fluid ports sit near the top and bottom edges, with their long axes aligned along the height of the narrow rear end face, with power/I/O between them. All connections face along the blade insertion axis. Rack guides support alignment; blind-mate connections are a design objective.

03

Cooling sidecar

Pumps, heat exchangers, filtration and serviceable plumbing outside the compute blade.

WHAT MUST BE PROVEN

Serviceability is
a system property.

A replaceable blade needs defined isolation, drainage or dry-disconnect behavior, safe electrical disconnection and leak checking. Swappability does not by itself establish live hot-swap operation.

Platform reuse depends on compatible electrical, hydraulic, mechanical and control interfaces across generations. Flow uniformity, pressure loss, temperatures and long-term reliability require analysis and testing.
