Problems solved by technology

However, such vents often only partially vent the heat exchanger.
Furthermore, such an air outlet generates noise, which has a detrimental effect on heat exchangers arranged in or adjacent to the passenger compartment of the vehicle (eg for heaters)

Embodiment Construction

[0036] In FIG. 1 is a known heater 1 for heating the air which is fed into the passenger compartment of the motor vehicle here. The direction of flow of air is marked by arrow A in FIG. 1 . The air flow can flow downstream or upstream of the vehicle in any way. The illustrated heater 1 is a vertically arranged, so-called UT heater. At its upper end 2 and its lower end 3 , the heater 1 has a coolant tank 4 , 5 each, which at the same time serve as collectors for the coolant flowing through. The upper coolant tank 4 is divided by a schematically shown intermediate wall 6 into a front region 7 situated at the front and adjacent to the inflow section 9 and a rear region 8 located at the rear with the return section 10 .

[0037] A number of coolant pipes, here flat pipes 11 , are formed between the upper coolant tank 4 and the lower coolant tank 5 . Between the flat tubes 11 there are in each case corrugated fins 12 which improve the heat exchange with the air A flowing through...

Abstract

The invention relates to a heat exchanger, in particular for a stationary UT heating body (1) of a motor vehicle heater. According to the invention, said heat exchanger comprises a ventilation device which is embodied as a ventilation bore (22, 36) which is, in particular, embodied in the separating wall of the upper coolant tank (4) of the heating body and is located at a distance from the feed and return section (10).

Description

technical field [0001] The invention relates to a heat exchanger for at least one heat transfer medium, for example a heater for heating air entering the passenger compartment of a motor vehicle. Using such a heat exchanger, the invention also relates to a cooling circuit and an air treatment unit for a motor vehicle. Background technique [0002] Furthermore, heat exchangers are used for different purposes in automobiles. For example, heat exchangers are used in a broad sense for engine cooling, for example as coolant coolers, oil coolers, exhaust gas coolers and charge air coolers. Another common application area for heat exchangers in automobiles is to temper the air entering the vehicle cabin. Here, heat exchangers are used, for example, in the form of evaporators, condensers (or gas coolers), internal heat exchangers and heaters. [0003] At present, such heat exchangers have various structures and installation forms. When using at least one heat transfer medium tha...
