Gas-liquid-double-medium cooler capable of being applied to motor cooling

The invention provides a gas-liquid-double-medium cooler capable of being applied to motor cooling. The gas-liquid-double-medium cooler is characterized in that the cooler is mainly composed of a liquid flow cavity, a gas flow cavity and a heat exchange plate; the liquid flow cavity and the gas flow cavity are formed in the opposite side faces of the heat exchange plates respectively; the surface of the heat exchange plate is provided with a plurality of concave and convex points, the concave faces of the concave and convex points are located in the liquid flow cavity, and the convex faces of the concave and convex points are located in the gas flow cavity; the transverse cavity section of the liquid flow cavity is of a closed structure, and the two ends of the liquid flow cavity are of closed structures; the transverse cavity section of the gas flow cavity is of a semi-open structure, and the two ends of the gas flow cavity are in an open state; the two ends of the cavity wall of the liquid flow cavity are provided with liquid flow inlet holes and liquid flow outlet holes; the liquid flow direction in the liquid flow cavity is opposite to the gas flow direction in the gas flow cavity. The gas-liquid-double-medium cooler is simple in structure, easy to machine and high in heat dissipation efficiency.
