Embodiment Construction
[0024] The present invention is described in further detail below in conjunction with accompanying drawing (embodiment):
[0025] Refer to attached Figure 3-6 , the present invention is composed of a circular hollow inner and outer tubes 21, 22 and an oil cooling tube 20 interposed therebetween with a cooling fin 23. The inner and outer tubes 21, 22 are an aluminum tube that is processed and formed by cutting and punching , and the top of the outer tube 22 is provided with through-holes 221 relatively at both ends, and the heat sink 23 is formed by processing and forming a plurality of cooling holes 231 from an aluminum coil to form a vortex surface to improve heat dissipation. The screw seat 24 matched with the through holes 221 at both ends above, the two screw seats 24 are made of aluminum rods processed by a lathe to form a ⊥ stereotype, and the bottom of the screw seat 24 is provided with a concave welding part 241 and a protruding one that is hollow. Threaded assembly ...

The invention belongs to oil cooling tube technique field, specially relates to a method for manufacturing oil cooling tube. According to the invention, an internal tube, a external tube made of aluminum, and heat radiating fin made of aluminum with a plurality of heat radiation holes, are integrated into a light oil cooling tube in manner that the internal tube expands, and a plurality of snail bases and end caps are process with aluminum, a soldering section and a convex hollow group connection end are arranged on snail base bottom end, such that the snail base soldering sections are respectively soldered above the both ends of the external tube, the through holes are communicated, such that the hollow group connection end and the through holes form an oil inlet-outlet communicated with the oil tube. The invention has advantages of simple production process, low cost; low material cost, light products; high heat radiation efficiency, sufficient cooling-down of engine oil, enough engine force of attraction. The invention has reasonable design, easy accomplishment, high practice property.
Description
technical field [0001] The invention belongs to the technical field of oil cooling pipes, is an improvement on the prior art, and in particular relates to a method for making an oil cooling pipe. Background technique [0002] Traditional oil cooling tube production method: refer to the attached Figure 1-2 , two red copper tubes with different diameters are processed into an outer tube (11) by cutting and punching, and an inner tube (12) is formed by expanding the tube at the end of the cutting, and then a heat dissipation tube formed by brass coils is assembled together. The sheet (13) is tightly bonded therein, and through-holes (111) are provided at both ends near the top of the outer tube (11), so that the two ends of the inner and outer tubes (11, 12) are joined together and welded together. The two screw seats (14) processed by brass rods are then turned into two screw seats (14), so that the two screw seats (14) are respectively coated with flux and welded to the thro...
