Heat Exchanger with Ventilation

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 ).

1 . A heat exchanger for at least one heat transport medium, with at least one feed, at least one return and at least one ventilation device, wherein the ventilation device is arranged at a distance from at least one return opening in the heat exchanger. 
   
   
       2 . The heat exchanger as claimed in  claim 1 , wherein the ventilation device is formed at a distance from at least one feed opening in the heat exchanger. 
   
   
       3 . The heat exchanger as claimed in  claim 1 , characterized by a distance of at least 10 mm, preferably at least 15 mm, particularly preferably at least 20 mm, in particular at least 25 mm, between at least one ventilation device and at least one feed opening and/or between at least one ventilation device and at least one return opening. 
   
   
       4 . The heat exchanger as claimed in  claim 1 , wherein at least one feed opening and at least one return opening are arranged adjacent to each other. 
   
   
       5 . The heat exchanger as claimed in  claim 1 , wherein at least one ventilation device is arranged at a distance from the direct connecting section between at least one feed opening and at least one return opening. 
   
   
       6 . The heat exchanger as claimed in  claim 1 , which heat exchanger is designed as a heat exchanger which is arranged upright and has, advantageously, at least one coolant tank preferably located at the top. 
   
   
       7 . The heat exchanger as claimed in  claim 1 , which heat exchanger has a bottom depth deflection and/or is designed as a radiator. 
   
   
       8 . The heat exchanger as claimed in  claim 1 , wherein at least one ventilation device is designed in the form of one or more openings. 
   
   
       9 . The heat exchanger as claimed in  claim 1 , wherein at least one ventilation device is formed in a partition, preferably in an upper region of a partition of the heat exchanger. 
   
   
       10 . The heat exchanger as claimed in  claim 1 , wherein at least one ventilation device is formed in a coolant tank, preferably in a coolant tank located at the top of the heat exchanger. 
   
   
       11 . The heat exchanger as claimed in  claim 1 , in which at least one ventilation device has a flow limiting means which is designed, in particular, as a baffle, as a tube, as an integrally formed flange and/or as a hydrodynamic flow limiting means. 
   
   
       12 . The heat exchanger as claimed in  claim 1 , wherein at least one ventilation device is designed as an external ventilation device outside the heat exchanger body and/or the coolant tank. 
   
   
       13 . The heat exchanger as claimed in  claim 12 , wherein at least one external ventilation device is formed in a flange region which is optionally formed separately. 
   
   
       14 . A coolant circuit with at least one heat exchanger as claimed in  claim 1 . 
   
   
       15 . An air treatment device for motor vehicles, having at least one heat exchanger as claimed in  claim 1 . 
   
   
       16 . The heat exchanger, coolant circuit or air treatment device as claimed in  claim 1 , wherein at least one ventilation device is formed with respect to at least one subassembly of the heat transport medium circuit and/or with respect to the entire heat transport medium circuit in the region of a location mounted at a geodetically locally high point and/or essentially in the region of the location mounted at the geodetically highest point.
