Abstract: A temperature regulation device includes an upper plate and lower plate assembled together to form multiple circulation channels for a heat-transfer fluid to circulate in. The multiple circulation channels are grouped together in groups of channels running parallel to one another with a spacing between the channels referred to as an intra-group spacing. Two groups of channels with the same direction of circulation are separated from each other by an intermediate group of channels with an opposite circulation direction. The device also includes a connector assembled on the upper or lower plate that creates a fluid path for connecting two outlet collecting zones. The connector includes an external fluid inlet orifice and an external fluid outlet orifice.
