Description
Technical field
The utility model is related to a kind of micro-channel cold plates.
Background technology
Cold plate is a kind of common liquid-cooling heat radiation equipment, high power, big heat consumption module or equipment cooling is used for, since its is heavy
Amount is light, and heat exchange efficiency is high, simple in structure, the multiple fields such as extensive use and space flight, aviation, ship, automobile, electronics.For height
Heat flow density device, module and equipment cannot solve heat dissipation problem using common flow passage or finned cold plate, need to use and change
The hot higher micro-channel cold plate of coefficient.
Existing micro-channel cold plate structure as shown in Figure 1, micro-channel 1, encapsulating structure 2 including Precision Machining or etching,
Pipe fitting 3, micro-channel 1 are welded with encapsulating structure 2, and pipe fitting 3 is welded with encapsulating structure again.Therefore it is existing
Micro-channel cold plate, micro-channel processing is complicated, and cost is higher, and micro-channel cold plate encapsulating structure is complicated, and weld seam is more, is unfavorable for close
Envelope.
Invention content
The technical problem to be solved by the present invention is to provide a kind of micro-channel cold plates, and processing is simple, at low cost, sealing
Property it is good, compact-sized, heat exchange efficiency is high.
The utility model is described to solve above-mentioned technical problem and the technical solution adopted is that provide a kind of micro-channel cold plate
Micro-channel cold plate welds butt welding by bottom surface shell and seal nipple shell, by argon arc welding or electron beam and forms, seal nipple position
In micro-channel cold plate both ends, heat dissipation is realized by the coolant liquid of fluid in micro-channel cold plate.
Above-mentioned micro-channel cold plate, wherein the seal nipple is integrally machined with seal nipple shell, the bottom surface
Micro-channel on shell and the seal nipple shell can pass through hot investment casting, small tool sharpening, laser processing, fine electrical fire
Flower processing or lithography are made.
Above-mentioned micro-channel cold plate, wherein the seal nipple is using double O-shaped rubber ring radial seals.
The utility model comparison prior art has following advantageous effect：It is provided by the utility model to be used for module to be cooled
Or the micro-channel cold plate of equipment cooling to be cooled, cold plate is not used and produces common soldering processes, only with argon arc welding or electronics
The flat welding process of beam weldering, has prevented brazing process parameter and has groped the disadvantage that the time is long, of high cost, yield rate is relatively low, has processing
Simply, at low cost, good airproof performance is compact-sized, the high feature of heat exchange efficiency.
