    • The multi-tube heat exchanger includes a bundle of tubes which form fluid passages of first heat exchanging fluid, an outer shell which covers the bundle of tubes and form a fluid passage of second heat exchanging fluid, and a baffle plate which is arranged inside the outer shell in a direction intersecting an axial direction of the bundle of tubes and provided with a plurality of through holes through which respective tubes of the bundle are passed. Each of the through holes has such a shape that a portion of an outer peripheral face of the tube comes into contact with a portion of an inner peripheral face of the through hole, and a gap for passing the second heat exchanging fluid is formed between the other portion of the inner peripheral face and the outer peripheral face of the tube. It is possible to support the tubes with high dimensional accuracy, and to enhance heat exchanging efficiency by decreasing fluid resistance. It is also possible to make pitch of the through holes smaller and to make the heat exchanger compact.
    • 多管式热交换器包括形成第一热交换流体的流体通道的管束,覆盖管束并形成第二热交换流体的流体通道的外壳,以及布置在内部的挡板 外壳沿与所述管束的轴向相交的方向设置有多个通孔,所述束的各个管通过所述通孔。 每个通孔具有这样的形状:管的外周面的一部分与通孔的内周面的一部分接触,并且在第二热交换流体之间形成用于使第二热交换流体通过的间隙 内周面的另一部分和管的外周面。 可以以高尺寸精度支撑管,并通过降低流体阻力来提高热交换效率。 也可以使贯通孔的间距变小,使热交换器紧凑化。

    • An image data processing apparatus capable of performing processing at a high speed comprising a DRAM for storing display data including a plurality of first pixel data respectively indicating colors of a plurality of pixels arranged in a matrix and able to be simultaneously written with a plurality of first pixel data. Memory controllers are provided with a plurality of pixel data generation circuits provided corresponding to the plurality of first pixel data to be simultaneously written for performing color blending using the second pixel data and the third pixel data for blending a color indicated by corresponding second pixel data and a color indicated by third pixel data stored in the write address by a predetermined blending ratio to generate a new color so as to generate the first pixel data indicating the new color.
    • 一种能够进行高速处理的图像数据处理装置,包括DRAM,用于存储显示数据,该显示数据包括分别表示以矩阵排列的多个像素的颜色的多个第一像素数据,并且能够同时写入多个第一 像素数据。 存储器控制器设置有与要同时写入的多个第一像素数据相对应地设置的多个像素数据生成电路,用于使用第二像素数据和第三像素数据混合由相应的第二像素数据指示的颜色,以及 由存储在写地址中的预定混合比例的第三像素数据指示的颜色,以产生新颜色,以便产生指示新颜色的第一像素数据。
