En variante, un tube d'évacuation est disposé de façon à être éloigné d'une ligne droite virtuelle qui coupe en deux parties égales la distance entre les centres des tubes supérieur et inférieur desdits tubes en communication avec ladite région évacuation. Selon ledit mode de réalisation de la présente invention, l'efficacité d'échange thermique de l'échangeur thermique peut être fortement améliorée.
