[specific embodiment]
The present invention can be explained in more detail by the following examples, the invention is not limited to the following examples, open
The purpose of the present invention is intended to protect all changes and improvements in the scope of the invention；
The hollow liquid cooling cabinet board structure of microchannel, including plate 4,7 and of annular micro-channel tubes are had in conjunction with described in attached drawing 1~5
Cover board item 8, is equipped with oblong slots 6 on the plate face A5 of plate 4, and annular micro-channel tubes 7 are placed in oblong slots 6, are placed in oblong slots 6
7 small part of annular micro-channel tubes be placed in the outsides of oblong slots 6, be equipped with cavity 11 in the tubular body of annular micro-channel tubes 7,
The centre of cavity 11 is equipped with central tube 13, centre bore 14 is equipped in the centre of central tube 13, in central tube 13 and ring
Several partitions 12 arranged in the shape of a spiral around central tube 13 are equipped at intervals in cavity 11 between shape micro-channel tubes 7, by center
Cavity 11 between pipe 13 and annular micro-channel tubes 7 is separated into several fan-shaped microchannels arranged in the shape of a spiral, in the plate of plate 4
The face back side A5 i.e. plate face B9 are equipped with liquid cooling slot 3, and liquid cooling slot 3 is that multiple "u"-shaped grooves join end to end the composite structure to be formed,
It is equipped with the inlet opening 1 of perforation 4 outer wall of plate in one end of liquid cooling slot 3, is equipped with perforation 4 outer wall of plate in the other end of liquid cooling slot 3
Fluid hole 2, be respectively equipped with casting lug thereon 10 in the slot bottom two sides of liquid cooling slot 3, cover board item 8 is that multiple " u "-shaped items join end to end shape
At composite structure, cover board item 8 is placed in liquid cooling slot 3 and carries on a shoulder pole on casting lug thereon 10, and oblong slots 6 are multiple and are alternatively arranged,
Annular micro-channel tubes 7 are equipped in each oblong slots 6, the side that liquid cooling slot 3 is located at plate 4 is less than the area of half plate 4
In domain, vertical area that each oblong slots 6 cover on plate 4 some hanging down of falling into that liquid cooling slot 3 covers on plate 4
Straight region.
Implement the hollow liquid cooling cabinet board structure of the present invention with microchannel, cover board item 8 is placed in liquid cooling slot 3 simultaneously
Cover board item 8 and liquid cooling slot 3 are carried out welding encapsulation with vacuum brazing, in annular 7 profile of micro-channel tubes on casting lug thereon 10 by load
Suitable refrigerant and end to end formation oblong are injected, the annular micro-channel tubes 7 for forming oblong are placed in oblong slots 6
It is interior, in use, plate 4, which is placed in 4 top of plate according to liquid cooling slot 3, holds up setting, by the lower part of 4 plate face A5 of plate close to needs
Inlet opening 1 and fluid hole 2 are separately connected radiator by the precision instrument of cooling, and coolant liquid, accurate instrument are filled in liquid cooling slot 3
Heat is conducted to annular micro-channel tubes 7 after fever by device, and the refrigerant heat being equipped in annular micro-channel tubes 7 is made to distil upwards
(refrigerant that several fan-shaped microchannels arranged in the shape of a spiral play in each fan-shaped microchannel can absorb the work of heat
With), the coolant liquid in liquid cooling slot 3 that the refrigerant after distillation is arranged on encountering plate face B9 is conducted low by 4 plate body of plate
It is liquefied as liquid again after temperature radiation and flows downward, refrigerant repeats above-mentioned step after encountering the heat that precision instrument distributes again
Suddenly to achieve the purpose that reduce precision instrument temperature, since liquid cooling slot 3 of the invention is located at outside cabinet, so even if liquid cooling slot
The coolant liquid that leakage leaks out, which occurs, for the coolant liquid in 3 will not contact precision instrument and precision instrument is made to be damaged, and due to
The interface very little of annular micro-channel tubes 7, refrigerant are not easy to leak out, and reduce to minimum to the injury of precision instrument so can realize.
Part not in the detailed description of the invention is the prior art.
