Diff\u00e9rence de temp\u00e9rature<\/h2>\n

La diff\u00e9rence de temp\u00e9rature entre le fluide chaud et le fluide r\u00e9frig\u00e9rant est tr\u00e8s importante lors de la conception d’un \u00e9changeur de chaleur.<\/p>\n

Les temp\u00e9ratures plus basses du liquide de refroidissement absorbent plus de chaleur du fluide chaud que les temp\u00e9ratures plus chaudes du liquide de refroidissement. Par exemple, si vous avez bu un verre d’eau potable \u00e0 temp\u00e9rature ambiante, il est beaucoup plus efficace de le refroidir avec des gla\u00e7ons qu’avec de l’eau froide seule. Le m\u00eame principe s’applique aux \u00e9changeurs de chaleur.<\/p>\n

D\u00e9bit<\/h2>\n

Un autre facteur important est le d\u00e9bit des fluides dans les parties primaire et secondaire de l’\u00e9changeur de chaleur.<\/p>\n

Un d\u00e9bit plus important augmente la capacit\u00e9 de l’\u00e9changeur \u00e0 transf\u00e9rer la chaleur, mais un d\u00e9bit plus important signifie \u00e9galement une masse plus importante, ce qui peut rendre plus difficile la dissipation de l’\u00e9nergie.[\/et_pb_text][et_pb_text _builder_version=\u00a0\u00bb4.14.7″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb]<\/p>\n

Installation<\/h2>\n

En g\u00e9n\u00e9ral, la mani\u00e8re la plus efficace d’installer un \u00e9changeur de chaleur est de laisser les fluides circuler \u00e0 contre-courant (c’est-\u00e0-dire que si le liquide de refroidissement se d\u00e9place de gauche \u00e0 droite, le fluide chaud se d\u00e9place de droite \u00e0 gauche).<\/p>\n

Pour les \u00e9changeurs de chaleur \u00e0 faisceau tubulaire, le liquide de refroidissement doit entrer par la position d’entr\u00e9e la plus basse afin de garantir que l’\u00e9changeur de chaleur est toujours rempli d’eau.<\/p>\n

Avec les \u00e9changeurs de chaleur refroidis par air, il est important de prendre en compte le flux d’air lors de l’installation d’un refroidisseur. Toute partie obstru\u00e9e du noyau compromet la capacit\u00e9 de refroidissement.[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"
