Abstract

L’invention concerne un système d’empilement de refroidisseurs portables, dans lequel des refroidisseurs portables de formes et de tailles différentes peuvent être empilés de façon optimale et stable. Le système de refroidisseurs comprend un premier refroidisseur ayant une première taille et un second refroidisseur ayant une seconde taille, les première et seconde tailles étant différentes. Une paire de seconds refroidisseurs peut être empilée sur le premier refroidisseur, les seconds refroidisseurs étant disposés dans le sens de la largeur le long de la longueur du couvercle du premier refroidisseur. De cette manière, la longueur interne de la surface supérieure du couvercle du premier refroidisseur est légèrement supérieure à la largeur d’une partie inférieure des seconds refroidisseurs, et la largeur interne de la surface supérieure du couvercle du premier refroidisseur est plus de deux fois supérieure à la largeur de la partie inférieure des seconds refroidisseurs. Ainsi, deux seconds refroidisseurs peuvent être disposés dans le sens de la largeur le long de la longueur du couvercle du premier refroidisseur. La position adjacente des seconds refroidisseurs et des surfaces de verrouillage réciproque limite sensiblement le mouvement horizontal de la paire de seconds refroidisseurs sur le couvercle du premier refroidisseur.
