本考案は、主としてアルミニューム製の熱交換器用タンクにオイルクーラを内 装し、そのオイルクーラのボス部をタンクの貫通孔に液密に接続するオイルクー ラの取付構造に関する。 The present invention mainly relates to an oil cooler mounting structure in which an oil cooler is provided in a heat exchanger tank made of aluminum, and a boss portion of the oil cooler is connected to a through hole of the tank in a liquid-tight manner.
【０００２】[0002]
従来、アルミニューム製熱交換器用タンクにアルミニューム製のオイルクーラ を内装するには、タンクの外周面に穿設された貫通孔にオイルクーラのボス部を その内面側から突出させ、その突出部とタンクの貫通孔との間をティグ溶接によ り接合していた。 Conventionally, to install an aluminum oil cooler in an aluminum heat exchanger tank, the oil cooler boss protrudes from the inner surface of the oil cooler boss through a through hole formed in the outer peripheral surface of the tank. And the tank through hole were joined by TIG welding.
【０００３】[0003]
アルミニューム製熱交換器用タンクとアルミニューム製のオイルクーラとの接 合をティグ溶接により行うことは、量産性に欠ける欠点があった。 そこで本考案は、そのティグ溶接をなくすために、次の構成をとる。 Connecting the aluminum heat exchanger tank to the aluminum oil cooler by TIG welding had the disadvantage of lacking mass productivity. Therefore, the present invention employs the following configuration in order to eliminate the TIG welding.
