Embodiment Construction

[0037] The present invention can be applied in such as figure 1 Shown in heat exchanger 1. This may for example be a radiator for cooling a battery in a motor vehicle, operating in particular in a circuit containing known coolants, refrigerants or refrigerating fluids such as R134a or R744 (carbon dioxide) for short Those ones. It comprises a bundle of parallel tubes 2 . The tubes 2 are of the same length and each have a first longitudinal end 2A connected in a fixed and hermetic manner to the figure 1 The manifold 10 at the top of the is called the first manifold 10 . The tubes 2 are for example brazed to the first manifold 10 . Said manifold serves to collect the fluid arriving from the pipe 2, in other words it comprises an area in which the fluid is forced into the first manifold. Said manifold also serves to distribute the fluid through the pipe 2 , in other words it comprises a zone in which the fluid is forced to leave the first manifold 10 . The tube 2 is for exa...

Abstract

The invention relates to a manifold (10) for a heat exchanger (1), comprising a cover (31), an intermediate plate (41) and a header plate (51), said manifold (10) being used to collect and distribute fluids . According to the invention, the intermediate plate (41) defines together with the cover (31) a first fluid chamber (11) and together with the header plate (51) defines a second fluid chamber (12), said second chamber being independent of First chamber (11). The invention also relates to a heat exchanger comprising such a manifold (1) (10), and a method for manufacturing such a manifold (10).

Description

technical field [0001] The invention applies in the field of heat exchangers, such as battery coolers, and in particular batteries in vehicles with electric and / or hybrid motors. The object of the invention is an exchanger of this type and a manifold comprising said exchanger. Background technique [0002] Vehicles with electric and / or hybrid motors are powered by one or more batteries. One problem is that batteries tend to heat up and are therefore vulnerable to damage during operation. It is therefore necessary to use battery coolers to keep them at acceptable temperatures. Such coolers comprise a tube bundle which connects at least two manifolds to one another, in which manifolds the respective ends of the tubes are connected in a fixed and hermetic manner. Coolant then flows through tubes and headers to ensure heat exchange with the battery. [0003] One difficulty that needs to be overcome is the problem of cooling the batteries in an efficient, regulated and consis...
