Detailed description of the invention
Particular content of the present utility model is described in detail in conjunction with accompanying drawing.A kind of groove-type liquid cold plate, including base plate 1 and lid
Plate 2, between base plate 1 and cover plate 2, by filling, solder foil is integral braze-welded to be formed, and base plate 1 is provided with two serpentine-like adverse current arrangements
Hot fluid conduit 3 and cold fluid channels 4, the base plate 1 at hot fluid conduit 3 two ends is respectively equipped with and is connected with hot fluid conduit 3
Logical hot fluid liquid inlet joint 5 and hot fluid go out liquid joint 6, and the base plate 1 at cold fluid channels 4 two ends is respectively equipped with and cold flow body
Cold flow body liquid inlet joint 7 and cold flow body that conduit 4 is connected go out liquid joint 8, and described hot fluid liquid inlet joint 5, hot fluid go out
It is all one-body molded with base plate 1 that liquid joint 6, cold flow body liquid inlet joint 7 and cold flow body go out liquid joint 8, this hot fluid liquid inlet joint 5,
Hot fluid goes out liquid joint 6, cold flow body liquid inlet joint 7 and cold flow body and goes out the bottom of liquid joint 8 and increase the fillet of R2-R5, institute respectively
The hot fluid conduit 3 stated is or/and be respectively equipped with in cold fluid channels 4 and corresponding channel width and the flat tube 9 that highly matches, flat tube
9 length directions are consistent with the direction of corresponding conduit, and flat tube 9 thickness direction is consistent with the depth direction of corresponding conduit, conduit deep
Degree is 5mm, and channel width determines according to coolant rate.
Two snakelike conduits of processing adverse current arrangement in described base plate, two snakelike conduit density degree can be according to heat exchange
Requirement size is adjusted, if heat transfer requirements is higher, then needs to properly increase the density degree of snakelike conduit.Between conduit
The wall thickness soldering width not less than 5mm.Connector interface form can be processed according to actual operation requirements, and joint sealing form can
Employing end-face seal ring seals, it is possible to use the forms such as conical surface seal.
