    • A fin-tube type heat exchanger has parallel heat transfer tubes and a stack of a plurality of plate fins mounted on the tubes. Heat exchange is conducted between a first fluid flowing through the tubes and a second fluid flowing through the stack across each of the fins. Each fin has flat tube-mounting portions spaced in the longitudinal direction of the fin and formed with tube-mounting holes and a louver section disposed between each adjacent pair of tube-mounting portions. The louver section has elongated slats extending longitudinally of the fin and having side edges each spaced from an adjacent side edge of an adjacent slat. The slats are classified into two groups in respect of the cross-sectional shape. The slats of one group have generally flat cross-sections to reduce the resistance of the fin to the flow of the second fluid through the stack and are disposed in planes offset from the plane of the tube-mounting portions. The slats of the other group have V-shaped or inverted V-shaped cross-sections to increase stiffness of the fin in the longitudinal direction thereof.
    • 翅片管型热交换器具有平行的传热管和安装在管上的多个板翅片的堆叠。 在流过管的第一流体和跨过每个翅片流过堆叠的第二流体之间进行热交换。 每个翅片具有在翅片的纵向间隔开的扁平管安装部分,并且形成有管安装孔和布置在每个相邻的一对管安装部分之间的百叶窗部分。 百叶窗部分具有从翅片纵向延伸的细长板条,并且具有与相邻板条的相邻侧边缘间隔开的侧边缘。 板条在横截面形状上分为两组。 一组的板条具有大致平坦的横截面,以减小翅片对通过堆叠的第二流体的流动的阻力,并且设置在从管安装部分的平面偏移的平面中。 另一组的板条具有V形或倒V形横截面,以增加翅片在其纵向上的刚度。

    • An ammonia gas analyzer and a sulfuric acid converter utilized in the ammonia gas analyzer in which a sample gas is maintained at a relatively high temperature prior to entering the sulfuric acid converter to thereby prevent acidic sulfuric acid sulfates and/or ammonia sulfates from crystallizing and being deposited on the walls of the device. The ammonia gas analyzer includes gas sampling means, a gas measuring channel connected to the gas sampling means, a comparison gas channel connected parallel to the measuring gas channel with the measuring gas channel including an NH.sub.3 /NO converter for converting NH.sub.3 in a sample gas into NO and means for measuring a concentration of NH.sub.3 on the basis of variations of an amount of NO in the measuring gas channel with respect to that in the comparison gas channel. A first sulfuric acid converter has an inlet connected to the sampling means and an outlet connected to an inlet portion of the comparison gas channel for converting sulfuric acid, sulfate and sulfur trioxide in the sample gas into sulfur dioxide. A second sulfuric acid converter has an inlet connected to the outlet of the NH.sub.3 /NO converter and an outlet connected to an inlet of the measuring means.

    • A flat shaped header having a heat receiving side is attached to a semiconductor element mounted on a circuit board. The header having the heat receiving side is connected to another header having a heat receiving side attached to a plurality of heat radiating fins so as to form a heat exchanging radiator which heat radiating fins are installed at a peripheral portion of a body of electronic equipment. The heat generated by the semiconductor element is transmitted by liquid moving between the headers via flexible tubes and then to the heat radiating fins, which heat is discharged outside of the body of equipment. Since the flat shaped header and the flexible tubes are employed, a high heat generating semiconductor element and the heat radiating fins are thermally connected with ease without being influenced by the configurational condition in the equipment even when many semiconductor elements are mounted inside a small space.
    • 具有热接收侧的扁平头部安装在安装在电路板上的半导体元件上。 具有热接收侧的集管连接到具有附接到多个散热片的热接收侧的另一个集管,以形成散热片安装在电子设备主体的周边部分的散热片。 由半导体元件产生的热量通过液体通过柔性管在集管之间移动,然后传递到散热片,热量被排放到设备本体外部。 由于使用扁平形的集管和柔性管,因此即使在许多半导体元件安装在小空间内的情况下,高发热半导体元件和散热片也容易热连接而不受设备的结构条件的影响。
