1. an oil cooler for transmission:

  • Comprise multiple heat-exchange tubes stacked along the vertical direction;

    Between above-mentioned multiple heat-exchange tube, form the cooling water passage that Cooling Water passes through, and above-mentioned each heat-exchange tube is formed by the edge section manufacture of be combined with each other upper board and lower panel, and above-mentioned each heat-exchange tube possesses the oil passageway passed through for machine oil therein;

    Respectively form multiple groove at above-mentioned upper board and the relative part of lower panel, and mutually intersected to form by the groove of the groove and lower panel that make above-mentioned upper board, to form the oil passageway of interleaved structure;

    On above-mentioned upper board and the bottom surface of above-mentioned lower panel, form multiple ridge and multiple valley continuously, and above-mentioned multiple ridge and multiple valley are parallel to each other and extend along oblique line directions;

    Above-mentioned each heat-exchange tube, respectively form the flow channel flowed into for machine oil and the flow pass flowed out for machine oil, and each oil passageway of above-mentioned heat-exchange tube is interconnected at its two ends by above-mentioned flow channel and flow pass;

    Above-mentioned upper board, on the top of above-mentioned flow channel and flow pass, possess the upper flange projected upwards, and above-mentioned lower panel is in above-mentioned flow channel and flow pass bottom, possesses outstanding lower flange downwards;

    In above-mentioned top and lower panel, the continuous or discontinuous formation protuberance along above-mentioned ridge;

    The upper flange of adjacent heat-exchange tube and lower flange are mutually blocked and are established, and at least one flange in above-mentioned upper flange and lower flange, its end tilts to internal diameter direction.
