Plate is difficult to the needs of meeting different spaces many places heat source while radiating；B) runner integral structure is difficult to meet various heating sources difference
The radiating requirements of heat flow density；C) the attainable highest heat dissipation heat flow density of relatively efficient corrugated board structures is about at present
5W/cm2, it is difficult to meet part heat flow density and is up to 30W/cm2The radiating requirements of the above heat source.
Summary of the invention
The purpose of this utility model is: a kind of large-scale integrated micro-channels abnormity cold plate is provided, to solve different spaces many places
The technical issues of heat source difference heat flow density radiating requirements.
To solve this technical problem, the technical solution of the utility model is:
A kind of integrated micro-channels abnormity cold plate, the cold plate are divided into front-end and back-end two parts, and cold plate front end portion is

Frame strip of paper used for sealing 2 and inlet-outlet connector 3；Described front-end and back-end two parts are fixed together, and inner flow passage is integrated；Cold plate
Inside is disposed with flat tube 8, corrugated plating 6, microchannel 7, and flat tube 8 is arranged in cold plate front end portion, and corrugated plating 6, microchannel 7 are arranged in
Cold plate rear end part.
Preferably, the corrugated plating 6, the height of the microchannel 7 and the back-end box strip of paper used for sealing 2 height
Match, deviation is not more than 0.05mm.
Preferably, the matched of the height of the flat tube 8 and front end frame strip of paper used for sealing 5, deviation are not more than 0.05mm.
It is welded inside the cold plate using vacuum brazing mode.
The fixed mode of front-end and back-end two parts is vacuum brazing.
The microchannel 7 is used for high heat flux density radiating area.
The beneficial effects of the utility model are:
1, radiate while the heat source of different spaces many places: cold plate is divided into front-end and back-end two parts, and front end portion is to sink
Structure meets the cooling heat source of down space distribution, and rear end part is slab construction, the cooling heat source of spatial distribution in satisfaction.
2, the heat dissipation of different heat flow densities: being disposed with a variety of heat-sink units such as flat tube, corrugated plating, microchannel inside cold plate,
Meet the radiating requirements of different heat flow densities.
3, the heat dissipation of superelevation heat flow density: the microchannel heat-sink unit arranged in cold plate can be such that local heat-sinking capability reaches
30W/ square centimeters or more.
