  • Patent number: 10207376
    Abstract: An oil cooler has a core portion (1) formed of stacked core plates (5), a bottom plate (2), a second bottom plate (3) and a top plate (4), and these are brazed in a furnace. The core plate (5) has oil communication ports (13), cooling water communication ports (14) and an oil outlet port (15). The lower end core plate (5) has a boss portion (16) surrounding the cooling water communication port (14) and a boss portion (17) surrounding the oil outlet port (15). Opening portions (32, 33) opposite to the boss portions (16, 17) are formed through the bottom plate (2). Therefore, at the time of the brazing, a melted brazing material is not excessively gathered in the boss portion (16, 17) because the melted brazing material is absorbed in the opening portions (32, 33).

  • Patent number: 10180289
    Abstract: A heat exchanger for cooling batteries in hybrid or electric vehicles includes a plurality of spaced apart, discrete heat exchanger panels, each having a coolant inlet manifold section, a coolant outlet manifold section, and a plurality of coolant flow passages extending between the inlet and outlet manifold sections. The inlet and outlet manifold sections of the discrete panels are connected by tubes to define continuous coolant inlet and outlet manifolds, each having a coolant opening. The flow of coolant through discrete panels may be balanced by providing the fluid flow passages of the panels with various cross-sectional areas and/or hydraulic diameters, depending partly on the proximity of each panel to the coolant opening. In an embodiment, where the panels are formed from pairs of stamped plates, variation of the cross-sectional area and/or hydraulic diameter of the coolant flow passages may be achieved by deliberately offsetting the plates during assembly.

  • Patent number: 10017073
    Abstract: A vehicle power module assembly is provided. The assembly may include a first frame, a second frame, and power stages. The first frame may define a first pair of coolant cavities. The second frame may define a second pair of coolant cavities in communication with the first pair of cavities to define a serial coolant path. Each of the frames may house one of the power stages disposed between the respective pairs of cavities such that coolant flowing through the cavities is in thermal communication with the power stages. The assembly may further include a pair of endplates, one of which defines a channel to divert coolant from a last of the pair of coolant cavities to the outlet cutouts in substantial registration with one another. Each of the first frame and second frame may further define a pass-through fluidly connecting the pair of coolant cavities.
