Embodiment Construction
[0030] The present invention is applied, for example, to figure 1 shown in the heat exchanger. The heat exchanger is intended in particular to be located in a motor vehicle heating, ventilation and / or air conditioning system. Such a heat exchanger 1 is, for example, an evaporator of a cabin air-conditioning circuit of a motor vehicle.
[0031] The heat exchanger 1 may comprise a core bundle 10 of parallel tubes 2 . Such a heat exchanger 1 comprises nozzles, respectively inlet nozzles 3 and outlet nozzles 4 , in the direction of circulation F of a first fluid, in particular refrigerant, which circulates through the tubes 2 . The first fluid thus circulates through the tubes 2 of the heat exchanger 1 , forming a circulation loop from the inlet nozzle 3 to the outlet nozzle 4 . The second fluid sweeps the core bundle 10 from the inlet face 11 of the core bundle 10 to the outlet face (not visible) of the core bundle 10 . This second fluid is in particular outside air intended ...

The invention relates to a tube (2) of a heat exchanger (1) intended to allow an exchange of heat between a first fluid and a second fluid flowing in contact with the tube (2), said tube (2) comprising an upper plate (22) and a lower plate (21) positioned facing one another and defining an internal space (25) in the tube (2) in which the first fluid is able to circulate, each of the plates (21, 22) comprising a bottom (23) and at least one edge (24), said plates (21, 22) being in contact with one another at said edge (24), characterized in that said tube (2) comprises a deflection screen (30) secured to the edge (24), the deflection screen (30) comprising a first wall (31) extending transversely to the bottoms (23) and arranged to deflect the second fluid toward said bottoms (23). The invention also relates to a bundle of such tubes and to a heat exchanger comprising such a bundle. The invention also relates to a method for producing a heat exchanger tube plate.
Description
technical field [0001] The invention is in the field of heat exchangers, such as motor vehicle heat exchangers, in particular heat exchangers located in heating, ventilation and / or air-conditioning systems of motor vehicles. In a preferred application, the heat exchanger in question corresponds to an evaporator arranged in a vehicle air conditioning circuit or circuit. However, other applications for these heat exchangers are also envisioned without departing from the scope of the present invention. Background technique [0002] Evaporators comprising core tube bundles are known. A first fluid circulates within each tube from the inlet to the outlet of the core bundle and exchanges heat with a second fluid, such as air flow, across the tube from the inlet face of the core bundle to the outlet face of the core bundle. Sweep through the tubes as they pass through the core tube bundle. [0003] The tube includes a lower plate and an upper plate, each provided with a base and...
