The invention provides a vehicle-mounted heat exchanger. The vehicle-mounted heat exchanger comprises a first shell, a second shell and an oil cooler core, the oil cooler core comprises a top plate and a bottom plate, a plurality of stacked oil channel chips are arranged between the top plate and the bottom plate, the first shell and the second shell serve as side walls, the top plate and the bottom plate define a space for containing the oil channel chips with the side walls, a connecting device for connecting the first shell and the second shell is arranged in the space. According to the connecting device, a front sheet metal shell and a rear sheet metal shell can be connected in a welding mode and the like, it is ensured that when the pressure of a water path of the heat exchanger is high, the sheet metal shells only slightly deform, and weld joints are prevented from cracking. According to actual measurement, the water side bearing pressure of the heat exchanger with the structure can be increased to 1.0-1.5 MPa and is far higher than that of most heat exchangers on the market at present.
本发明提供一种车载换热器,包括第一壳体、第二壳体、油冷器芯子,所述油冷器芯子包括顶板和底板,所述顶板和底板间设有堆叠的若干油通道芯片,所述第一壳体、第二壳体作为侧壁与所述顶板、底板围合成收容油通道芯片的空间,所述空间内设有用于连接第一壳体、第二壳体的连接装置。本发明提供的连接装置可以将前后两块钣金壳体通过焊接等方式连接起来,确保换热器在水路压力较高时,钣金壳体只发生轻微的变形避免焊缝开裂。经过实测,使用本发明结构的换热器水侧承受压力可以提高到1.0‑1.5MPa,远超目前市面上的大部分换热器。
