It is relatively better that copper, aluminium section bar install the finned cooler structural reliability of heat pipe additional, but be subject to the restriction of metal heat-conducting character, and thermal resistance is larger, due to blocking of temperature-uniforming plate, air can not be on radiating fin Rational flow, temperature-uniforming plate and radiating fin thermograde are obvious, heat-sinking capability is limited; The screen type condenser structure of carbon steel material is a kind of condenser structure of good heat dispersion performance, yet the coefficient of heat conduction of carbon steel material is lower, and owing to being iron material, weight is larger, simultaneously the evaporation tube of carbon steel material and being connected of aluminium material evaporimeter with higher thermal conducting power, need use transition metal connector, not only increases cost, and weld bond increases, the reliability of heat abstractor reduces; With " U " type pipe box, wear the fin-tube type cooler concretio of pressing the type that is expanded into after fin, radiating efficiency is higher, but the mouth of pipe of " U " used type pipe is more, need could form the whole evaporation pipeline being communicated with the sealing of little " U " type elbow welding, a large amount of " U " type elbow sealing ports reduces the reliability of the whole cooling system being communicated with, the life-span of phase-change heat radiating device is easily caused risk, and welding difficulty is larger, and manufacturing process is complicated.
Summary of the invention
Condenser structure for phase-change heat radiating device provided by the invention, comprising: evaporation coil 1, radiating fin 2, fixed dam 3, the air inlet mouth of pipe 4, liquid back pipe mouth 5; At least by two continuous tubing of whole piece, through multiple tracks loop, parallel bending is made described evaporation coil 1, and amount of thermal conduction and heat transfer area obviously increase, and uniform temperature strengthens, and heat dispersion obviously improves and improves.
Condenser structure for phase-change heat radiating device provided by the invention, the admission mouth of pipe 4 and liquid back pipe mouth 5 on the continuous evaporation coil 1 of described whole piece, all do not use transition metal connector, evaporimeter direct and heat abstractor welds together, the connection of evaporation coil 1 does not have " U " type elbow to connect, reduced a large amount of weld bonds, can effectively reduce material cost and welding difficulty, the security reliability of heat abstractor obviously strengthens.
Described fixed dam 3 when condenser structure moulding, the centre-to-centre spacing L of adjacent evaporation coil between each perforate
1all be greater than the centre-to-centre spacing L that is arranged on evaporation coil adjacent in each perforate
2the axis of evaporation coil forms an angle with horizontal direction shape at grade, can produce gravity structure, reduces the resistance that vapour, liquid two-phase working substance flow and produce in opposite directions in evaporation tube, accelerate condensation working medium automatic back flow, effectively reduce the heat transfer resistance of phase-change heat radiating device.
The little fin that described radiating fin 2 is regular geometric shapes, dispersed arrangement is arranged, is closely fixed on described evaporation coil 1, there is polygon effect, can effectively increase the area of dissipation of unit volume, shorten lamina air flow passage, strengthen air permeability, improve heat-sinking capability.
The lateral opening arranging on described fixed dam 3 and longitudinally perforate, correspondence is arranged on the curved end of evaporation coil, can make the moulding of phase-change heat radiating device rapid-assembling, improves assembling production efficiency.
Described evaporation coil 1 is that through multiple tracks loop, parallel crooked making forms the continuous tubing of whole piece, evaporation coil can extend with the variation expansion of heat flow density, area of dissipation can change arbitrarily, can rationally meet heat radiation requirement, can realize again the reasonably optimizing of heat dispersion and economic performance.
