Definitions

• the invention relates to a heater for vehicles in particular according to the preamble of claim 1.
• Such a device known from practice should be reduced in size and more economically producible.
• a bladed guide device is provided axially in front of the combustion chamber of the burner. This is structurally complex and also leads to a relatively large volume. The complicated structure of the device is further increased by a conventional radial engagement of the glow plug in the previous burners to ignite the fuel to be fed into the burner of the heat exchanger.
• the invention provides that the central opening of the heat exchanger be closed by a part of the blower forming the first and an approximately right-angled second leg containing one-piece angle flange.
• This one-piece angular flange practically fulfills the function of a housing part, in which in particular the blower can be integrated.
• the first leg of this angular flange ve runs in a plane running approximately parallel to the axis of the heat exchanger and the second leg in a plane oriented vertically there.
• the two legs cover the opening of the heat exchanger with the burner located therein.
• blower as a side channel blower with an axially divided in half side channel i that half with the air inlet and outlet in the only parallel to the axis of the heat exchanger aligned Sche angle of the angled flange.
• the combustion air a can be introduced in a structurally extremely simple manner in a twist-like manner into the open face of a tubular combustion comb.
• a radially tangential air supply duct leading the end face of the combustion chamber is openly formed in the front end of the second leg of the angle flange covering the heat exchanger opening.
• This duct is directly connected to the outlet of the side duct of the fan installed in the same angle flange.
• the air supply duct is closed to the circumference within the second leg of the angle flange when the angle flange is placed on the opening of the heat exchanger, in that it is covered by the heat exchanger and / or the combustion chamber.
• the glow plug can be mounted in a very advantageous, structurally simple manner in the second leg of the angular flange and can engage in the burner parallel to the axis of the heat exchanger and thus also to the axis of the burner.
• This arrangement leads to the further advantage that in the end face of the second leg of the angled flange a simple connection channel open to the end face of this leg can be formed between the glow plug and the feed channel for the combustion air.
• the circumferential closure of this connecting channel is again ensured by placing the angle flange on the opening of the heat exchanger, as a result of which parts of the heat exchanger or the burner bring about the necessary closing of the connecting channel.
• the connecting channel serves to effect a known ventilation of the glow plug in a secondary flow to the combustion air flow.
• the glow plug is located in a glow plug chamber, which is open on the radially outside of the combustion chamber wall.
• the glow plug chamber is separated from the inside of the combustion chamber only by a fuel-absorbing lining of the combustion chamber. Because the glow plug is directly adjacent to the fuel-absorbing combustion chamber lining, the glow plug chamber does not require its own fuel supply.
• Combustion chamber In the area where the glow plug chamber is only facing the interior of the combustion chamber lining Combustion chamber is separated, there is an ignition hole connecting the two chambers in the lining. The air flowing around the glow plug can flow out of the glow plug chamber into the combustion chamber through this ignition hole.
• a conventional flame sensor in gat devices according to gat can be structurally extremely simple to run coaxia to the heat exchanger axis in the second leg of the angle flange.
• the burner of the heat exchanger is arranged in the design of the heater according to the invention only within the heat exchanger and at most protrudes slightly with its connection area into the second leg of the angular flange.
• the end face of the burner lies directly against the overall flat end face of the second leg of the angle flange.
• the attachment of the heat exchanger can be achieved only by ei clamping between the opening edge of the heat exchanger and the angle flange, so that no special mounting devices for the burner are required.
