Uncovered engine oil cooler

无盖机油冷却器

Abstract

本实用新型涉及车用无盖机油冷却器,包括底板和由多片芯片重叠而成的散热芯子,每片芯片都具有进油口和出油口,其内设有翅片,相邻芯片之间设有隔圈;所述的底板焊接在顶层芯片上方,其上开设有进油孔、中间进油孔、中间出油孔和出油孔;所述进油孔和中间进油孔之间通过进油油道连通;所述的中间出油孔和出油孔之间通过出油油道连通。本实用新型的机油冷却器,在所述底板上直接设置油道使油孔之间连通,可省去盖板,大大简化了产品结构,由于只存在底板上的进油孔和出油孔与减速箱或发动机缸体相连的一个密封面,降低了产品的渗漏几率。同时,由于零件的减小,可降低产品的体积、重量和制作成本。
The utility model relates to an uncovered engine oil cooler used for a vehicle, comprising a lower plate and a heat radiation core composed of multiple overlapping chips, each of which is provided with an oil inlet and an oil outlet. A fin is arranged in the chips, a space ring is arranged between the contiguous chips, and the lower plate is welded above the chip at the top layer. The oil inlet, an intermediate oil inlet, an intermediate oil outlet and the oil outlet are equipped on the lower plate, the oil inlet and the intermediate oil inlet are connected through an oil channel, and the intermediate oil outlet and the oil outlet are connected through an oil outlet channel. The oil channel directly arranged on lower plate of the engine oil cooler of the utility model makes the oil inlet and the oil outlet are communicated, a cover plate is saved, and the structure of the product is greatly simplified. Since only one sealing surface that the oil inlet and the oil outlet are communicated with a reducer casing or an engine cylinder exists on the lower plate, the leakage rate of the product is decreased. Meanwhile, since the elements are decreased, the volume, the weight and the manufacture cost can be decreased.
