Description
Technical field
The utility model relates to a kind of radiator, especially relates to a kind of anti-corrosion and high strength heat dissipating pipe.
Background technique
The radiator that current car, truck, passenger vehicle, engineering machinery, farming equipment etc. mate, most employing single hole tubular construction or hourglass tubular construction, the former bears, and system pressure is lower, radiating efficiency is lower, and the latter is due to the restriction of its processing technology, and decay resistance is poor.Along with the develop rapidly of the development particularly automotive industry of science and technology, the automobile produced is more and more high-grade, and power also progressively promotes, and in system, pressure is also more and more higher, more and more higher to the requirement of endurance quality, decay resistance, traditional heat sinks does not catch up with the speed of development of automobile far away yet.
Summary of the invention
The purpose of this utility model is: provide the anti-corrosion and high strength heat dissipating pipe that a kind of corrosion resistance and good, radiating efficiency and bearing strength are high.
For achieving the above object, the utility model adopts following technological scheme: a kind of anti-corrosion and high strength heat dissipating pipe, heat dissipating pipe forms through high frequency welding by being with two-sided composite material, has utilizingthebrazing material layer, have the preserving timber bed of material inside tube wall outside the tube wall of heat dissipating pipe; The side wall of heat dissipating pipe has the interior bending that one or more caves inward into dual-layer wall thick structure, what interior bending top longitudinal direction has interruption is convenient to many slits that solder passes through, the length L1 of slit is 1mm ~ 20mm, the width L2 of slit is less than 5.0mm, distance L3 between the edge of adjacent slots is that 2mm ~ 12mm, distance L3/ length L1 is less than 0.6; Bending I top I and bending II top II close contact in opposite side tube wall or opposite side in side, heat dissipating pipe internal layout is become separately independently upper and lower pore by interior bending, the both sides forming surface contact of interior bending.
Further, bending I top I and bending II top II close contact in opposite side in side, the slit on corresponding interior bending top is interlaced.
Further, many interior bendings are arranged on the both sides tube wall of heat dissipating pipe, have the adjacent interior bending adjoining outer walls close contact forming surface contact in a place at least.
The beneficial effects of the utility model are: because heat dissipating pipe forms through high frequency welding by being with two-sided composite material, be compounded with utilizingthebrazing material layer outside tube wall, tube wall internal layer is compounded with the preserving timber bed of material, improve decay resistance.The side wall of heat dissipating pipe has the one or more interior bending caved inward, and bending top close contact in interior bending top and opposite side tube wall or opposite side, heat dissipating pipe is divided into upper and lower two-tube hole or multitube hole by interior bending, improves radiating efficiency.Both sides due to interior bending abut against forming surface contact together, become dual-layer wall thick structure, substantially increase bearing strength.
Adopt the radiator of the utility model heat dissipating pipe, the coefficient of heat transfer of radiator is greatly increased, and while meeting relatively high power engine radiating Capability Requirement, also add structural strength and bearing strength, pressure-bearing can reach 350KPa, improves 1 times than traditional intercooler; Use the radiator decay resistance of the utility model heat dissipating pipe to be greatly improved simultaneously, be conducive to the clean of engine water jacket, without brazing flux in pipe, while extending product working life, also extend the working life of motor.The utility model can be widely used in car, truck, passenger vehicle, engineering machinery, farming equipment radiator etc.
