Embodiment Construction

[0062] figure 1 A device for thermal regulation is shown, for example an electric heating device for a fluid of the motor vehicle 1 for a heating and / or air-conditioning system.

[0063] The electric heating device 1 is, for example, an additional heating device that allows heating the fluid before it enters the circuit, for heating the fluid intended for heating the interior of the electric vehicle.

[0064] According to another example, the electric heating device 1 is arranged upstream of the evaporator of an air conditioning circuit which can be configured in heat pump mode in order to heat the refrigerant fluid.

[0065] According to yet another example, the electric heating device 1 is arranged upstream of a heat exchanger using the coolant of the internal combustion engine as heat transfer medium.

[0066] Such an electric heating device 1 may also be arranged upstream of a heat exchanger intended to thermally condition an electrical energy storage device, sometimes ca...

Abstract

The invention relates to a device for thermally conditioning a fluid for a motor vehicle, comprising: at least one heat module comprising a core and a shell defining a circuit for guiding the fluid that is to be heated or cooled between the core and the shell, a fluid inlet box (209a) and a fluid outlet box, the inlet box (209a) having at least one fluid inlet canal (225a, 225b) communicating with the fluid guiding circuit. According to the invention, the fluid inlet canal (225a, 225b) has at least one substantially curved portion which is configured to generate a swirling movement in the fluid. The invention also relates to a heating and / or air conditioning apparatus comprising such a device.

Description

technical field [0001] The invention relates to a device for the thermal conditioning of a fluid, for example an electric heating device for a fluid of a motor vehicle. The invention also applies more particularly to a heating and / or air-conditioning installation for a motor vehicle comprising such a heating device. Background technique [0002] The reheating of the air intended to heat the interior is generally ensured by the air flow passing through the heat exchanger, more specifically by the heat exchange between the air flow and the fluid. In the case of internal combustion engines, the fluid is usually coolant. [0003] Such heating methods may prove to be unsuitable or insufficient to ensure heating and defogging and defrosting of the motor vehicle interior. [0004] However, a method is desired for rapidly and efficiently heating the vehicle interior in very cold environments, or also when the temperature increases very rapidly, in particular to ensure reheating of...
