Le dissipateur thermique (10) comprend une première partie de conduction de chaleur (11) et au moins une ailette de dissipation de chaleur (12). Une première surface (111) de la première partie de conduction thermique (11) est utilisée pour ajuster une première carte de circuit imprimé (300) du dispositif de commande à distance. Lesdites ailettes de dissipation de chaleur (12) sont formées sur une seconde surface (112) de la première partie de conduction de chaleur (11) opposée à la première surface (111). Lesdites ailettes de dissipation de chaleur (12) forment un conduit d'air de dissipation de chaleur (121). Le ventilateur (20) comprend un support (22) et un ventilateur (21), et le ventilateur (21) est monté sur le dissipateur thermique (10) au moyen du support (22), de telle sorte que la direction de sortie d'air du ventilateur (21) coïncide avec la direction d'extension du conduit d'air de dissipation de chaleur (121). Les modes de réalisation de la présente invention concernent également un dispositif de commande à distance (1000). Comme le ventilateur (21) est monté sur le dissipateur thermique (10) au moyen du support (22), en choisissant un support approprié (22), le plan de montage du ventilateur (21) peut être rendue sensiblement à fleur du plan où se trouve le conduit d'air de dissipation de chaleur (121), la direction de sortie d'air du ventilateur (21) coïncide avec la direction d'extension du conduit d'air de dissipation de chaleur (121), et moins de flux d'air formé par le ventilateur (21) s'échappe lors de l'entrée dans le conduit d'air de dissipation de chaleur (121) et moins de flux d'air dans le conduit d'air de dissipation de chaleur (121) est perdu.
