Abstract:
An electric power-steering control device has a substrate, a heat-generating component, and a heat-storing body. The heat-generating component is disposed on one surface of the substrate and generates heat when activated. The heat-storing body is capable of storing the heat from the heat-generating components. The heat-storing body has a main body having a rectangular plate shape and disposed on the one surface of the substrate. The heat-storing body has a notch section or a recess section.
Abstract:
An electronic control unit includes a board, a high-heat-generating device, a controller, a heat-dissipating member, and a heat-conducting member. The high-heat-generating device is mounted on a surface of the board. The heat-dissipating member has a surface located facing the surface of the board. The surface of the heat-dissipating member is recessed to form a recess capable of holding the high-heat-generating device. The heat-conducting member is located between the board and the heat-dissipating member and in contact with both the high-heat-generating device and the recess to transfer the heat of the high-heat-generating device to the heat-dissipating member. The recess is shaped to match a shape of the high-heat-generating device.
Abstract:
An electronic control unit includes: a substrate; a plurality of heat generating components that are provided on one surface of the substrate and generate heat during operation; a heat conducting component that is formed of a material having a heat conductivity equal to or higher than a predetermined value and is provided on the one surface of the substrate such that at least a part of the heat conducting component is located between the plurality of heat generating components; and a controller that is provided on the substrate and controls the operation of each of the plurality of heat generating components to control the object to be controlled.
