A battery cooling device for a vehicle is provided to cool a battery cell. The device includes a phase change material (PCM) that cools the battery cell and is disposed to exchange heat with the battery cell and cooling water for cooling the phase change material is disposed to exchange heat with the phase change material. Thus, the phase change material is heated by heat generation of the batterycell and at the same time the phase change material is cooled by heat absorption of the cooling water thereby facilitating continuous phase change of the phase change material.

A solenoid section of a solenoid three-way valve includes a yoke attached to a valve housing and formed from a bottomed cylindrical main yoke and an auxiliary yoke closing an open end of the main yoke, a coil assembly inside the yoke, a fixed core slidably fitted into a hollow portion of a bobbin and abutted against a ceiling wall of the main yoke, a movable core facing the fixed core and passing through the auxiliary yoke, and a coil spring compressed between the cores. The fixed core is abutted against the wall by a predetermined spring load and by electromagnetic attraction force between the core and wall based on coil energization. A valve rod is slidably supported in a housing hole, having one end separably abutted against an outer end of the movable core and an opposite end abutted against a valve body.

An airbag equipped with a sub-chamber may include a main chamber expanding by being injected with gas in a collision, and a sub-chamber formed by folding a panel-shaped chamber to be combined with themain chamber and have self-supporting force, the sub-chamber assisting supporting force of the main chamber by expanding with the main chamber.

An air conditioner consists of condenser for carrying out heat exchange and water drainage plate for collecting condensed water. It features that supplying unit is set at one side of condenser for providing condensed water generated in heat exchange to condenser and supplying unit is used to spray condensed water on condenser.

The invention relates to the technical field of an inversion power supply, and discloses a high-performance inversion power supply having a single-phase asynchronous motor soft starting function. The high-performance inversion power supply mainly comprises a current limiting ring and a soft starting control module, wherein the inversion power supply acquires an error amount between an AC output current effective value and a current limiting given value, an output control factor is obtained by the current limiting ring, output voltage amplitude given quantity is obtained by subtracting the output control factor and AC output voltage effective value feedback quantity from AC output voltage amplitude quantity, the output voltage value is reduced after the output voltage amplitude given quantity is subjected to three-loop control, the soft starting control module is used for detecting an input signal of the inversion power supply and sending a control signal to a controller of the inversion power supply when the input voltage signal reaches a set value, and the controller is used for controlling amplitude of a sine wave signal according to the control signal so that the fundamental wave of the sine wave is continuously risen to 1 from 0 and the output AC voltage is gradually risen. The high-performance inversion power supply has the advantages that a circuit structure is simple and reliable.
