    • A heat exchange tube for a heat exchanger is provided to obtain an optimum equilibrium point between a flow rate and a flow amount of EGR(Exhaust Gas Recirculation) gas passing through the heat exchange tube, thereby keeping high heat exchange efficiency in a path and limiting pressure loss to a minimum. A heat exchange tube(1) for a heat exchanger includes a fin structure(2) incorporated inside, wherein the fin structure has a sectional shape in an approximately rectangular channel type waveform with a curved surface formed with waveform corrugation by a predetermined wavelength in the lengthwise direction. When assuming a width of the channel shaped waveform is H and a wavelength of the waveform corrugation is L, a value of H/L is controlled in the range of 0.17-0.20.
    • 提供一种用于热交换器的热交换管,以获得通过热交换管的EGR(排气再循环)气体的流量和流量之间的最佳平衡点,从而在路径中保持高热交换效率和限制 压力损失最小。 一种用于热交换器的热交换管(1)包括内部结合的翅片结构(2),其中翅片结构具有大致矩形通道型波形的截面形状,在波形波形中形成波形波形预定波长 纵向。 当假设通道形状波形的宽度为H且波形波形的波长为L时,H / L的值被控制在0.17-0.20的范围内。
