Abstract

The present invention relates to an auxiliary heater using the exhaust gas of a vehicle, and collects the air flowing through the engine room of the vehicle to be in contact with the exhaust pipe to increase the temperature, while increasing the space utilization of the engine room to the existing heating device. In addition, it can be used as an auxiliary heating system.

Characteristic implementation means for this is the exhaust pipe (1 ') wrapped around the outer diameter of the exhaust pipe (1') for discharging the exhaust gas generated in the engine 1 is heated means for heating the air flowing into the engine room (1) Heat transfer takes place through the high temperature exhaust gas flowing through the) is heated.

Description

Auxiliary heater using exhaust gas of vehicle {SUPPORT HEATER USING WASTE GAS OF VEHICLE}

The present invention relates to an auxiliary heater using exhaust gas of a vehicle, and more particularly, to an auxiliary heater using exhaust gas of a vehicle to be supplied to a vehicle interior by heating an outside temperature by using exhaust gas discharged at a high temperature from an engine after combustion. It is about.

In general, the air-conditioning system of the vehicle is to provide a comfortable environment for people who ride in the vehicle under all weather and conditions, and to prevent driver's glass windows from becoming cloudy or frost to secure the driver's watch for safe and comfortable driving. In particular, the heating system warms the air in the cabin and also serves as a defroster to prevent the front glass from becoming cloudy due to moisture.

In addition, the heating device uses heat generated from the engine and heat other than the engine, and the exhaust heater using the double exhaust gas has a structure in which a heat exchanger is installed in the exhaust pipe to warm air and send it to the vehicle interior. It is.

However, such an exhaust heater has to be provided with a heat exchanger in the middle of the exhaust pipe, and an air circulation pipe must be installed. There is a problem.

Therefore, the present invention has been invented to solve the above-mentioned problems in view of the above-mentioned conventional problems, and collects the air flowing through the engine room of the vehicle and makes contact with the exhaust pipe to increase the temperature to increase the space utilization of the engine room In addition to the existing heating system, it can be used as an auxiliary heating system.

Characteristic implementation means for this is that the heating means for heating the air flowing into the engine room is heated by heat transfer through the hot exhaust gas flowing through the exhaust pipe wrapped around the outer diameter of the exhaust pipe for exhausting the exhaust gas generated from the engine It becomes a structure.

1 is a schematic configuration diagram of an auxiliary heater using exhaust gas of a vehicle according to the present invention;

<Explanation of symbols for the main parts of the drawings>

1: Engine 1 ': Exhaust pipe

2: Dashboard

3: heating means 3a: inlet

3b: heating pipe 3c: discharge part

Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a schematic configuration diagram of the auxiliary heater using the exhaust gas of the vehicle according to the present invention, the heating means 3 for heating the air flowing into the engine room is generated by the exhaust gas from the engine 1 It is provided in the exhaust pipe (1 ') for discharging, the inlet (3a) for collecting the air flowing into the engine room from the heating means (3), and the air introduced from the inlet (3a) The heating pipe 3b surrounding the exhaust pipe 1 'and the high temperature air discharged through the heating pipe 3b are configured to provide heat transfer through the high temperature exhaust gas flowing through the exhaust pipe 1'. It is composed of a discharge portion (3c) to be collected to flow toward).

Here, the inlet part 3a, the heating pipe 3b, and the outlet part 3c constituting the heating device 3 are integrally formed as one pipe or separated from each other, and then relatively adjacent to each site. Of course, it forms a wide inlet to effectively introduce air.

In addition, the front part of the inlet part 3a constituting the heating device 3 may be formed along the width of the front part of the engine room in order to collect as much air as possible.

Therefore, when the outside air flowing into the front of the engine room is collected through the inlet portion 3a of the heating device 3 and introduced into the heating pipe 3b, the external cold air passing through the heating pipe 3b is exhausted. The hot exhaust gas and heat transfer in the pipe 1 'are heated.

Subsequently, the air heated while passing through the exhaust pipe 1 'is introduced into the discharge portion 3c connected to the dashboard 2, and is introduced into the room as the driver of the room operates the switch.

As described in detail above, the present invention collects the air flowing through the engine room of the vehicle and contacts the exhaust pipe to increase the temperature, thereby increasing the space utilization of the engine room and using it as an auxiliary heating device in addition to the existing heating device. In this case, it is possible to reduce fuel consumption.

Claims (1)

Heating means (3) for heating the air flowing into the engine room is provided in the exhaust pipe (1 ') for discharging the exhaust gas generated from the engine 1, the heating means (3) from the outside to the engine room The inlet part 3a which collects the inflowing air, the heating pipe 3b which heat-transmits the air which flowed in from this inlet part 3a through high temperature exhaust gas, and discharges it through this heating pipe 3b. In the configuration consisting of a discharge portion (3c) for collecting the hot air to be introduced into the dashboard (2), The heating pipe (3b) is the auxiliary heater using the exhaust gas of the vehicle, characterized in that is installed wound around the exhaust pipe (1 ').
