What the purpose of this utility model was such to reach, a kind of ripple oil duct gilled radiator, including an oil inlet pipe, one
Flowline and one group of cooling fin for being arranged between oil inlet pipe and flowline and being connected to respectively with oil inlet pipe and flowline, it is described
Cooling fin is formed by welding by a pair of of heat sink by edge, it is characterised in that: the heat sink is spaced compacting in the width direction
There are several waveform areas, has respectively constituted a Welding Area, phase between the opposite Welding Area of a pair of of heat sink again between several waveform areas
It is mutually welded and fixed and by several interruption-like separations in waveform area, a pair of of heat sink has complemented each other to form between opposite waveform area
The section of one ripple oil duct, the ripple oil duct is wavy and the distance between two sides heat sink is identical.
In a specific embodiment of the utility model, distinguished at the cooling fin upper and lower ends by heat sink
It is formed with an opening, the opening is connected to the oil inlet pipe of upper and lower ends and flowline respectively.
In another specific embodiment of the utility model, described oil inlet pipe one end is formed with an oil inlet, institute
The one end for the flowline stated is formed with an oil outlet.
