    • PROBLEM TO BE SOLVED: To provide a heat exchanger for improving cooling performance by distributing a liquid-phase refrigerant separated from gas in a header tank evenly to a plurality of flat tube inlet end parts.
      SOLUTION: When the refrigerant is flowed in from one end of an upper header tank 134 in a width direction and is flowed out to the other end of the upper header tank 134 in the width direction, the upper header tank 134 is connected with the inlet end part of an outgoing flat tube group 131 having an insertion allowance h within a predetermined range with respect to a height dimension H1 of an inner space of the upper header tank 134, and a lower header tank 136 includes an adjusting member 137, with a hole diameter d within a predetermined range opened with respect to a height dimension H2 of the inner space of the lower header tank 136, which is provided so as to divide the inlet end part of a return flat tube group 132 on a downstream side into two with respect to the width direction from a boundary section of an outlet end part of the outgoing flat tube group 131 and the inlet end part of the return flat tube group 132. Thereby the cooling performance is improved.

      SOLUTION: The heat exchanger comprises a plurality of flat tubes 3 provided between an upper side header 5 and a lower side header 2 arranged horizontally and fins 4 fixed between the flat tubes 3. A connection tube 1 into which refrigerant flows is arranged at one end of the lower side header 2 and a connection tube 6 out of which the refrigerant flows is arranged at the other end. The refrigerant flowing into a flow-in tube passes through the flat tubes 3 and flows out of the connection tube 6. An extension portion 7 is arranged on at least one header pipe with its length once or more the inner diameter of the header pipe. The flow of the refrigerant is stabilized by the extension portion 7.

    • PURPOSE:To maximize a heat-exchange rate by reducing the sectional areas of the opening ends of each path in succession in the leeward direction from the windward direction in the heat exchanger in which corrugated fins are arranged between each of the meandering multipass flat heat transfer pipe sections. CONSTITUTION:A meandering flat heat transfer pipe 16 has multipaths 16a- 16n of a uniform sectional area, and a meandering pipe end member 17 with opening sectional-areas 17a-17n of which path sectional-areas reduce in succession in welded to the end sections through braze, etc. Refrigerant inlet ends are arranged so that the sectional areas of the opening ends of each path are reduced in succession in the leeward direction 5 on an evaporator and refrigerant outlet ends are arranged so on a condenser. Accordingly, since the quantity of a refrigerant is changed in response to the temperature difference of air, there exists no unequal refrigerant superheating region, and the heat-exchange rate can be increased without decreasing temperature difference between air and the refrigerant.
    • 目的:通过在每个蜿蜒多通道平面传热之间布置波纹状散热片的热交换器中,从沿逆风方向依次减小每个路径的开口端的截面面积来最大化热交换率 管段。 构成:蜿蜒平坦的传热管16具有均匀截面积的多路径16a-16n,以及曲折的管端部件17,其开口截面面积17a-17n的路径截面面积连续地减少焊接到端部 通过钎焊等。制冷剂入口端被布置成使得每个路径的开口端的截面积在蒸发器上的背风方向5上连续地减小,并且制冷剂出口端被布置在冷凝器上。 因此,由于制冷剂的量随着空气的温度差而变化,所以不存在不均匀的制冷剂过热区域,并且可以在不降低空气和制冷剂之间的温差的情况下提高热交换率。
