Title
(EN) NEW HEAT EXCHANGE TUBE
(FR) NOUVEAU TUBE D’ÉCHANGE DE CHALEUR
(ZH) 新型热交换管
Abstract
(EN)
Provided is a heat exchange tube, comprising a spiral tube body (1), wherein two ends of the tube body (1) are respectively a water inlet end (2) and a water outlet end (3); the tube body (1) is a flat tube; two sides of a cross section of the tube body (1) are both arc-shaped; and upper and lower side walls of the tube body (1) are both evenly provided with protruding first bosses (4) and second bosses (5), with adjacent first bosses (4) and second bosses (5) abutting against each other.
(FR)
L'invention concerne un tube d'échange de chaleur, comprenant un corps de tube en spirale (1), deux extrémités du corps de tube (1) étant respectivement une extrémité d'entrée d'eau (2) et une extrémité de sortie d'eau (3) ; le corps de tube (1) est un tube plat ; deux côtés d'une section transversale du corps de tube (1) sont tous deux en forme d'arc ; et des parois latérales supérieure et inférieure du corps de tube (1) sont toutes deux pourvues de premiers bossages (4) et de seconds bossages (5) saillants, les premiers bossages (4) et des seconds bossages (5) adjacents venant en butée les uns contre les autres.
(ZH)
一种热交换管,包括呈螺旋状的管体(1),管体(1)的两端分别为进水端(2)以及出水端(3),管体(1)为扁平管,管体(1)的截面的两侧均为圆弧形,管体(1)的上下两侧壁均匀设有凸出的凸台一(4)以及凸台二(5)且相邻的凸台一(4)与凸台二(5)相贴靠。
