Definitions

  • the invention relates to a method for heating at least a vehicle driven by a combustion engine, such as a bus, a van, a truck, a motorcar, a working machine or like, whereby a resistance arrangement or like is being used, that exploits during use of the vehicle electric energy produced by the electric system of the vehicle, such as a generator and/or an accumulator belonging to the same, and that has been built into the vehicle's upholstery, such as to the bottom, the walls/doors, the ceiling and/or like of the vehicle and, by which at least one or several internal surfaces of the vehicle are being warmed up.
  • a combustion engine such as a bus, a van, a truck, a motorcar, a working machine or like
  • seat heaters for heating the vehicle during driving the same.
  • This kind of electric seat heaters that are built into the seat upholstery belong gene- rally to the vehicle's original equipment, but such may also be acquired as supplementary accessories to be installed afterwards either inside the seat upholstery or on top of the same .
  • a usual seat heater operates usually so, that it may be switched on by a separate operating switch, whereafter it automatically gets switched off when the temperature of the seat has risen above a certain limit temperature.
  • the relatively short warming period of the seat heater is not, however, able to improve significantly the driving circumstan- ces either, in case the basic heating of the vehicle, that is traditionally carried out by blowing air, that has been warmed up by cooling the motor, does not work satisfactorily.
  • the application document DE 30 26 122 and patent GB 1 085 535 there has been presented heating solutions, that are in principle based on electric resistance heating.
  • the former is intended to warm up the interiors of particularly caravans, camping vans, travelling vans or cars or the like, by placing an electric resistance arrangement, that is advantageously built-in with a glass fiber reinforced polyester material into the upholstery of the vehicle in questi- on.
  • the basic heating of the vehicle according to the solutions offered by this application must be furthermore based essentially on traditional techniques in other words on that, that heat being transferred from the motor cooling system is being blown to the vehicle's interior by nozzles, that have been placed at suitable points, because the power of the resistors presented in the application in question are dimensioned only with a view to occasional supplementary heating in order to compensate the defective power of the vehicle's basic heating or bad thermal insulation.
  • the method according to the invention is primarily characterized in, chat basic heating of the vehi- cle's interior, such as of the cab, the cabin, the trunk and/or like, at least during driving the vehicle is being produced continuously by means of an electric heat exchange arrangement, that is placed into the vehicle's floor, walls/doors, ceiling and/or correspondingly.
  • the method according to the invention gives first of all "free hands" for development of techniques particularly in order to improve the efficiency of motors, because significantly less waste energy from the motor is needed for basic heating of the vehicle's interiors. This waste energy may be needed in the future only e.g. for blowing heat for the wind screen or windows particularly in order to prevent them from getting frosted, the meaning of which is very minimal with respect to usual basic heating of the vehicle.
  • the most important fact is, that the method according to the invention enables significantly more comfortable or in other words more homogeneous and "draughtless" indoor air for the vehicle than presently.
  • the invention enables on the other hand that, that it is possible to exploit the electric heat exchange arrangement above for preheating of the vehicle in a way, that usual seat heaters need not be used at all, because heat reflecting e.g. from the ceiling warms up also the corresponding surfaces by radiation.
  • the invention relates to a heat exchange apparatus functioning according to the method, also, that is represented in more detail in the preamble of the independent claim directed to the same.
  • the primary characteristics of the heat exchange apparatus are represented in the characterizing part of the corresponding claim.
  • the heat exchange apparatus gives on the other hand also a great liberty to development of motor techniques, because waste energy from the motor is needed in the future only e.g. for frost removal of the wind screen and the windows.
  • the heat exchange apparatus according to the invention is first of all very easy to install and maintain with a view to the vehicle's original composition and retrofit of the same as well e.g. by changing only the damaged elect- ric resistors or like while the reparation measures of traditional heating systems based on water circulation are known to be very laborious.
  • the heat exchange apparatus according to the invention may be easy retrofitted as well e.g. by adding e.g. one additional generator and accumulator to the control center connected to the electric system, by means of which the total power of the electric resistors being used may be produced. It is furthermore possible to use elements based on peltier-phenomen in the electric heat exchange arrangement, by means of which also cooling of the vehicle's indoor air may be carried out in addition to heating of the same simply by changing the polarity of the elements.
  • the heat exchange apparatus according to the invention enables also, that the interior of the vehicle, that is equipped with e.g. a block heater, is being preheated by the heat exchange apparatus according to the invention, the control center of which is connected also to the current feed of the block heater, in which case it is not anymore needed to exploit traditional seat heaters at all.
  • Fig 2 shows a principle of coupling of an advanta- geous heat exchange apparatus exploiting the method according to the invention with the vehicle's electric system and
  • Fig 3 shows an example of placement of an electric resistor or like belonging to the heat exchange apparatus according to the invention into the internal structures of the vehicle.
