Abstract
The utility model discloses a novel heat sink plate for experiment. The heat sink plate comprises a copper sheet, wherein heat radiation holes are formed on the copper sheet; and heating wires are arranged among the heat radiation holes; Harbin bearing (HRB) aviation black paint is arranged on the copper sheet; the wall thickness of the copper sheet is 1.5mm; and the heat sink plate is welded by using silver-copper solders. The heat sink plate with the design has the advantages that the heat radiation holes are formed on the copper sheet, so that the heat radiation effect of the heat sink plate is enhanced; and the heat sink plate is obvious in heat radiation effect and is easy to implement; the heating wires are arranged among the heat radiation holes, and are uniformly paved, so that heating is easily realized by the heat sink plate, and high heating uniformity can be achieved; the HRB aviation blank paint is sprayed to the copper sheet, so that a heat radiation function of the heat sink plate is improved; and heat sink plate is welded by using silver-copper solders, so that welding spots are smooth and clean, air output is reduced, and vacuum performance of equipment is effectively improved.
Description
Technical field
The utility model relates to a kind of device of simulating cosmic experiment, especially a kind of experimental installation of simulating the cold darkness environment in universe.
Background technology
Heat sink promptly is the device that refers to simulate with liquid nitrogen wallboard inside face japanning the cold darkness environment in universe on the space engineering.
Present cosmic experiment requires more and more accurate, and also can be extremely more and more harsher to the requirement of experiment environment many times, especially to the temperature of simulation environment, is the major issue that the cosmic experiment device will solve always.An important indicator of heat sink quality is exactly heat sink in-to-in heat radiation and thermal radiation capability.Traditional is heat sink because all there is apparent in view defective in the restriction of the manufacture craft of heat sink plate in heat radiation and thermal radiation link, thereby has directly influenced the effect of whole cosmic experiment.Also have at present enterprise to select to carry out cosmic experiment, but the expense of operation and maintenance is all higher from the heat sink of external import the whole series.
So, need badly at present and a kind ofly can either realize that uniform and stable heat radiation and comprehensive even thermal-radiating experiment use heat sink plate.
The utility model content
The utility model purpose: to the deficiency of prior art, we grope through long-term practice, have created a kind of novel experiment and have used heat sink plate.
Technical scheme: in order to realize above-mentioned utility model purpose, the technical scheme that the utility model adopted is: heat sink plate is used in a kind of novel experiment, comprises that copper plate, said copper plate are provided with louvre, are provided with heater strip between the said louvre.It is pitch-dark that said copper plate is provided with the HRB aviation.
Said copper plate wall thickness 1.5mm is welded into and uses silver-copper brazing alloy when heat sink.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, copper plate is provided with louvre, has strengthened heat sink radiating effect, not only effect obviously and be easy to realize; 2, be provided with heater strip between the louvre, heater strip is evenly laid, and make that heat sink heating ratio is easier to realize, and heating is more even; 3, it is pitch-dark that copper plate is provided with the HRB aviation, increases considerably heat sink thermal radiation function; 4, be welded into and use silver-copper brazing alloy when heat sink, make solder joint bright and clean, reduce and tolerance, effectively improve the vacuum performance of equipment.
Description of drawings
Accompanying drawing is the structural representation of a kind of novel experiment of the utility model with heat sink plate.
The specific embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, the present technique scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.
As shown in the figure, heat sink plate is used in a kind of novel experiment, comprises that copper plate 1, said copper plate 1 are provided with louvre 2, are provided with heater strip 3 between the said louvre 2.It is pitch-dark that said copper plate 1 is provided with the HRB aviation, the copper plate 1 wall thickness 1.5mm that is used for making.
In the time of practical implementation, said copper plate 1 is welded into uses silver-copper brazing alloy when heat sink.
