【図面の簡単な説明】[Brief explanation of drawings]

第１図に水冷却器ユニット用熱交換器の横断面図、第２
図、第３図に従来より使用している伝熱管（インナーフ
ィンチューブと内面溝付管）を示す。第４図に本考案で
ある溝付電縫伝熱管の帯状鋼板に溝の成形展開図、第５
図はその断面における溝形状の例を示す。第６図に帯状
銅板を丸め、長手方向に連続的に溶接した（電縫）管の
断面形状の例を示す。 １２・・・帯状の平板、１３・・・溝、１４・・・電縫
部、１５・・・フラット部分。Figure 1 is a cross-sectional view of the heat exchanger for the water cooler unit, Figure 2
Figures 3 and 3 show conventionally used heat transfer tubes (inner fin tubes and inner grooved tubes). Figure 4 is a developed view of forming grooves on a band-shaped steel plate of the grooved electric resistance welded heat exchanger tube of the present invention, and Figure 5.
The figure shows an example of the groove shape in the cross section. FIG. 6 shows an example of the cross-sectional shape of a tube made by rolling a strip of copper plate and welding it continuously in the longitudinal direction (ERW). 12... Belt-shaped flat plate, 13... Groove, 14... Electric resistance stitching part, 15... Flat part.
