    • A method for manufacturing an aluminum heat exchanger includes the steps of: obtaining a heat exchanger tube 2 by forming a Zn thermally sprayed layer on a surface of an aluminum flat tube core so as to adjust Zn adhesion amount to 1 to 10 g/m2; obtaining a heat exchanger core by alternatively arranging the heat exchanger tube 2 and an aluminum fin 3 and brazing the heat exchanger tube and the fin with end portions of the heat exchanger tube connected to aluminum headers in fluid communication; and forming a chemical conversion treatment coat (corrosion resistance coat) on a surface of the heat exchanger core by subjecting the surface of the heat exchanger core to chemical conversion treatment using at least one chemical conversion treatment agent selected from the group consisting of phosphoric acid chromate, chromic acid chromate, phosphoric acid zirconium series, phosphoric acid titanium series, fluoridation zirconium series, and fluoridation titanium series. The obtained heat exchanger has a long last good corrosion resistance and can prevent occurrence of fin detachment and pit corrosion.

    • An air conditioner for air conditioning the interior of a compartment includes a compressor and an electric motor. The compressor compresses refrigerant gas and changes the displacement. The electric motor drives the compressor. A motor controller rotates the motor at a constant reference speed. A detection device detects information related to the thermal load on the air conditioner. A current sensor detects the value of current supplied to the electric motor. A controller controls the compressor based on the detected thermal load information and the detected current value. The controller computes a target torque of the compressor based on the thermal load information. In accordance with the computed target torque, the controller computes a target current value to be supplied to the electric motor. The controller further controls the displacement of the compressor such that the detected current value matches the target current value.

    • A heater containing viscous fluid, which is sheared to generate heat. The heater is provided with an electromagnetic solenoid that includes a case, a solenoid coil housed in the case, and a core extending through the case. The heater further has a heating chamber and a sub-oil chamber. Viscous fluid is moved between the heating chamber and the sub-oil chamber through a communication bore. The core extends toward the communication bore. A coil spring urges the core toward the communication bore. Excitation of the electromagnetic solenoid moves the core away from the communication bore. The core opens and closes the communication bore and pumps the viscous fluid into the communication bore when the solenoid is cycled on and off. As a result, the heat output is accelerated.
    • 含有粘性流体的加热器,其被剪切以产生热量。 加热器设置有电磁螺线管,其包括壳体,容纳在壳体中的螺线管线圈和延伸穿过壳体的芯部。 加热器还具有加热室和副油室。 粘性流体通过连通孔在加热室和副油室之间移动。 核心向通信孔延伸。 螺旋弹簧将核心推向连通孔。 电磁螺线管的激励使芯离开通信孔。 当螺线管开启和关闭时,核心打开和关闭通信孔,并将粘性流体泵入连通孔。 结果,加速了热输出。
