Abstract
The invention discloses a bidirectional internal bend heat radiating pipe. One or a plurality of inwardly recessed internal bend is respectively formed in large face pipe walls on two sides of the heat radiating pipe; the top ends of the internal bends on two sides have close contact; the interior of the heat radiating pipe is spaced into an upper pipe hole and a lower pipe hole independent to the upper pipe hole; and the upper and lower sides of the internal bend form a double-layered composite structure formed by surface contact, so heat radiating efficiency and bearing strength are improved.
Description
Technical field
The present invention relates to a kind of radiator, especially relate to a kind of two-way interior bending radiating tube.
Background technology
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 auto 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 object of the invention is: a kind of radiating efficiency and the high two-way interior bending radiating tube of bearing strength are provided.
For achieving the above object, the present invention adopts following technical scheme: a kind of two-way interior bending radiating tube, the both sides large facial canal wall of radiating tube respectively has the one or more interior bending simultaneously caved inward, the top close contact of bending in the top of bending in a and b, in bending in a, b, radiating tube inside is partitioned into separately independently upper and lower pore by bending, and in a, bending contacts composition two-layer composite with the forming surface of both sides up and down of bending in b.
Further, radiating tube width h1 be 26mm ~ 50mm, thickness h 2 for 1.6mm ~ 2.0mm, tube wall thickness t be 0.25mm ~ 0.35mm.
In described a, in bending and b, the close contact place, top of bending scribbles soldering paste.
Described radiating tube is formed by high-frequency welding, and weld seam is in radiating tube one end.
The invention has the beneficial effects as follows: due to the large facial canal wall in both sides of radiating tube respectively have one or more cave inward in bending, in both sides, radiating tube is divided into upper and lower two-tube hole or multitube hole by bending top close contact, improve radiating efficiency, the both sides up and down of interior bending abut against forming surface contact together and constitute two-layer composite, substantially increase bearing strength.Adopt the radiator of radiating tube of the present invention, the coefficient of heat transfer of radiator is greatly increased, and while meeting relatively high power engine radiating Capability Requirement, adds structural strength and bearing strength, pressure-bearing can reach 350KPa, improves nearly 1 times than traditional charge air cooler; Use the radiator decay resistance of radiating tube of the present invention to be greatly improved, this invention heat radiation is conducive to the clean of engine water jacket simultaneously, without brazing flux in pipe, while prolongation product service life, also extends the service life of engine.The present invention can be widely used in car, truck, passenger vehicle, engineering machinery, farming equipment radiator etc.

Detailed description of the invention
The present invention is a kind of New structure heat radiator radiating tube, and it is the two-tube hole of a kind of ratio-frequency welding or multitube hole radiating tube, and aluminum foil material forms by carrying out high-frequency welding after shaping.As can be seen from the first embodiment of the present invention shown in Fig. 1, in the middle part of the both sides large facial canal wall of radiating tube, respectively there is an interior bending caved inward, the top also close contact relative to the top of bending 4 in the b on the large facial canal wall of right side of bending 3 in a on the large facial canal wall of left side.From cross sectional shape, at two middle side parts of radiating tube, respectively there is bending 4 in bending 3 and right side b in left side a that a place caves inward simultaneously, the top close contact of bending 4 in the top of bending 3 in a and b, is partitioned into separately independently upper and lower two pores by radiating tube inside.Fig. 3 is the partial schematic diagram marking A place in Fig. 1 and Fig. 2, and as seen from the figure, upper hem 1 and the lower hem 2 of bending 4 in bending 3 and b in a abut against forming surface together and contact composition two-layer composite.Fig. 4 is the partial schematic diagram marking B place in Fig. 1 and Fig. 2, and radiating tube is formed by high-frequency welding, and weld seam 5 is in radiating tube one end, and in a, in bending 3 and b, the close contact place, top of bending 4 scribbles soldering paste, the top high-frequency welding of bending 4 in bending 3 and b in a.The present embodiment, radiating tube width h1 is 26mm ~ 50mm, thickness h 2 for 1.6mm ~ 2.0mm, tube wall thickness t be 0.25mm ~ 0.35mm.Prove by experiment, said structure size makes structural strength and bearing strength obtain optimal effectiveness, and decay resistance obtains large increase simultaneously.
From the second embodiment of the present invention shown in Fig. 2, the partial schematic diagram that composition graphs 3 marks the partial schematic diagram at A place, Fig. 4 marks B place can be found out, the both sides large facial canal wall of radiating tube respectively has two interior bendings simultaneously caved inward, and the top of bending 3 in two a on the large facial canal wall of left side and the top of bending 4 in two b on the large facial canal wall of right side be relative also close contact respectively.Radiating tube inside is partitioned into separately independently upper and lower three pores by interior bending, and upper hem 1 and the lower hem 2 of bending 4 in bending 3 and b in a abut against forming surface together and contact and form two-layer composite.Equally, radiating tube is formed by high-frequency welding, and weld seam 5 is in radiating tube one end.
The present invention can also take other embodiment, the large facial canal wall in the both sides as radiating tube respectively have three cave inward simultaneously in bending, the corresponding close contact in the top of bending in both sides, radiating tube inside is partitioned into separately independently four pores by interior bending.
Above-described embodiment is several way of realization provided by the present invention, and the present invention is not limited to above-mentioned detailed description of the invention, and the improvement that all those skilled in the art carry out without creative work and distortion, all belong to protection scope of the present invention.
