An electronic control unit includes a plurality of heating elements, a substrate, a heat sink, and a housing. The substrate includes a heating region on which the plurality of heating elements are collectively mounted. The heat sink is provided to be opposed to one surface of the substrate, and includes a radiating part, which is disposed in correspondence to the heating region of the substrate and receives heat generated by the plurality of heating elements.

The heat sink includes a fixation part, which is disposed separately from the radiating part and to which an outer edge part of the housing is fixed.

In some embodiments, a cooling system for an induction charger includes a thermal conditioning module in fluid communication with an induction charging assembly, which includes a dock and an induction charging module. The dock can be configured to receive a portable electronic device, such as a cell phone, that is configured to accept inductive charging from the induction charging module. The thermal conditioning module can include a fan or other fluid encouraging assembly, ducting, and a thermoelectric device (e.g., a Peltier device). A fluid, such as air, can flow from the fan and across and/or through the thermoelectric device, thereby conditioning the fluid. The conditioned fluid can be provided to the dock to at least partially offset the heat generated by the inductive charging and/or the portable electronic device.

A power conversion device such that heat dissipation can be improved is obtained. The power conversion device includes a power conversion circuit unit that converts direct current into alternating current using a semiconductor switching element, a heatsink on which the power conversion circuit unit is mounted, and which has a first passage through which a cooling medium is caused to pass, and a frame body that houses the power conversion circuit unit, seals the power conversion circuit unit between the frame body and the heatsink, and has a second passage through which a cooling medium is caused to pass, wherein the first passage and second passage are connected at an interface between the heatsink and frame body, thereby configuring a cooling passage.

Method and systems for determining when to cancel coolant stop. An initial coolant temperature value is measured. The initial coolant temperature value is used to create Multiple Control Valve (MCV) opening thresholds. A first threshold is generated for MCV opening threshold for engine speed. A second threshold is generated for MCV opening for intake air mass flow. A comparison is made between the first threshold and the currently measured engine speed and/or a comparison is made between the second threshold and the currently measured intake air mass flow. The comparison(s) are then used to determine when to cancel coolant stop and open the MCV.

Effectively control the temperature of a control unit of a railway equipment inspecting and measuring apparatus, and install the control unit of the railway equipment inspecting and measuring on the roof of the passenger car. The first space is formed between the control unit and the heat insulating case. The second space is formed between the heat insulating case and the cover. In the first space, heat is conducted between the air in the first space and the heat exchange element by the first heat conducting member, and the first fan causes circulation of the air in the first space. In the second space, heat is conducted between the air in the second space and the heat exchange element by the second heat conducting member, and the air inside the second space is diffused by blowing the air from a suction port into the second space with the second fan.
