摘要： A heat transfer tube with internal grooves, wherein multiple rows of V-shaped streaky grooves (3), (3) --- are formed in the inner peripheral surface (2) of a tube main body (1a) symmetrically with respect to the axial direction of the tube and secondary grooves (6), (6), ---, (7), (7) --- of a specified depth are formed in a part of projected streaky parts (5), (5), --- formed between the V-shaped streaky grooves to reduce a pressure loss, and the width of the multiple rows of the V-shaped streaky grooves (3), (3), --- in circumferential direction is differentiated from each other to produce a swirl component in spiral direction, whereby the flow of refrigerant in the tube can be controlled properly even when a refrigerant flow rate is small to increase a heat transfer performance as large as possible.
摘要翻译：通过在管体（1a）的内表面上设置多排排列为V形图案的多排凹槽（3），使得排排相对于管轴方向对称，减小了压力损失并且通过在其间形成的突出部分（5）的一部分中形成规定深度的辅助槽（6），（7）。此外，即使制冷剂流量低，也可以通过使排列成V字形状的多个槽（3）的宽度在圆周方向上不相等而适当地控制管道内的制冷剂流动，产生涡流在螺旋方向上，尽可能地提高传热性能。

摘要： A heat exchanger capable of improving the heat exchanging performance while suppressing the increase in the pressure loss is provided. A heat exchanger (1), in which a large number of plate-shaped fins (21) are attached to outer peripheries of heat transfer tubes (20) through which a refrigerant flows, the heat exchanger (1) being for performing heat exchange with the air. Three rows of heat transfer tubes (20a, 20b, 20c) are arranged along an air flow direction. Among the three rows of the heat transfer tubes (20a, 20b, 20c), an inlet side heat transfer tube in a case of using as an evaporator or an outlet side heat transfer tube in a case of using as a condenser has the smallest diameter. In a case where the most windward side heat transfer tube has the smallest diameter, a tube diameter of the most windward side heat transfer tube is D1, a tube diameter of the middle heat transfer tube is D2, and a tube diameter of the most leeward side is D3, D1

摘要： Provided is a heat exchanger (10) for carrying out heat exchange between a refrigerant that undergoes a phase change during heat exchange, and another heating medium, the heat exchanger being provided with refrigerant headers (50), a plurality of multi-hole flat tubes (40), and a plurality of flat tubes (20). The refrigerant flows through the interior of the refrigerant headers (50). The multi-hole flat tubes (40) extend in a direction intersecting a lengthwise direction of the refrigerant headers (50). Within the multi-hole flat tubes (40) are formed a plurality of refrigerant flow channels through the interior of which the refrigerant flows. The flat tubes (20) are stacked in alternating fashion with respect to the plurality of multi-hole flat tubes (40). The other heating medium flows through the interior of the flat tubes (20). Additionally, the refrigerant headers (50) are arranged in such a way as to extend along a horizontal direction.
