    • An inlet header of a microchannel heat exchanger is provided with a first insert disposed within the inlet header and extending substantially the length thereof, and having a plurality of openings for the flow of refrigerant into the internal confines of the inlet header and then to the channels. A second insert, disposed within the first insert, extends substantially the length of the first insert and is of increasing cross sectional area toward its downstream end such that annular cavity is formed between the first and second insert. The annular cavity of decreasing cross sectional area provides for the maintenance of a substantially constant mass flux of the refrigerant along the length of the annulus so as to thereby maintain an annular flow regime of the liquid and thereby promote uniform flow distribution to the channels.
    • 微通道热交换器的入口集管设置有设置在入口集管内并基本上延伸的第一插入件,并且具有多个开口用于使制冷剂流入入口集管的内部区域,然后到通道 。 设置在第一插入件内的第二插入件基本上延伸第一插入件的长度,并且朝向其下游端具有增大的横截面积,使得在第一和第二插入件之间形成环形空腔。 横截面积减小的环形空腔提供沿着环形空间的长度维持制冷剂基本恒定的质量通量,从而保持液体的环形流动状态,从而促进流向均匀的通道。

    • A cooling system includes a compressor for compressing a refrigerant from a subcritical state to a supercritical state, a cooler for transferring heat from the refrigerant, an expander for expanding the refrigerant in the supercritical state, an expansion valve for expanding the refrigerant from the supercritical state to the subcritical state and an evaporator for transferring heat from a cooling fluid to the refrigerant in the subcritical state. Work extracted by the expander provides power to the compressor. A method for cooling a vehicle includes compressing a refrigerant from a subcritical state to a supercritical state, cooling the refrigerant, expanding the refrigerant in the supercritical state where work produced by expanding the refrigerant is used to compress the refrigerant, expanding the refrigerant from the supercritical state to the subcritical state, cooling a cooling fluid with the refrigerant in the subcritical state and cooling vehicle components with the cooling fluid.

    • A motion conversion mechanism for use between a rotating motion and a reciprocating motion, and an internal combustion engine adopting the said motion conversion mechanism are disclosed, in which the motion conversion mechanism is constituted such that a reciprocator having racks along the opposite inner sides thereof is combined with a pinion having teeth along a part of the circumference thereof. When the reciprocator performs reciprocating motions, the teeth of the pinion are meshed with either one of the racks, thereby letting the pinion continuously revolve. The internal combustion engine according to the present invention uses the said motion conversion mechanism in place of the crank and the connecting rod. Further, in this engine, the deceleration and acceleration of the reciprocator in the vicinity of the dead points is adjustable, and therefore, the internal combustion engine according to the present invention can be expected to attain to a state close to the constant pressure cycle which is an ideal state for an internal combustion engine. The internal combustion engine of the present invention will drastically increase the engine efficiency and the engine power.
