    Heat exchanger for gas heaters
    The present invention relates to a heat exchanger of an auxiliary heater for a gas-use vehicle, and more particularly, to a heat exchanger of an auxiliary heater for a gas-use vehicle to improve the efficiency of the auxiliary heater by expanding the heating portion of the water flowing into the auxiliary heater from the engine.
    3 shows a conventional auxiliary heater, the configuration of which includes a gas tank 4 for supplying gas to the engine 2, a heat exchanger 20 connected to the gas tank 4, and raising a temperature of water; , A pump 8 for circulating and simultaneously circulating the cooling water of the engine 2 to the heat exchanger 20, and a heater core 10 into which water whose temperature is raised in the heat exchanger 20 is introduced, and the heater core ( It consists of a fan 12 for introducing the heat generated in 10) into the room.
    However, although the heat exchanger using the gas is installed in a manner of heating the pipe in which water is circulated with a gas burner, there is a problem in that the efficiency of the heat transfer surface of the pipe is small.
    Accordingly, the present invention is invented to solve the above problems, the object of the present invention is to provide a heat exchanger of a secondary heater for a gas use vehicle that maximizes the combustion efficiency during the combustion of gas by expanding the heating portion of the water flowing into the auxiliary heater from the engine. There is this.
    The present invention to achieve the above object, the gas tank 4 for supplying gas to the engine 2, the heat exchanger 20 connected to the gas tank 4 to increase the temperature of the water, the engine (2) Pump 8 for circulating and circulating cooling water at the same time as the heat exchanger 20, and a heater core 10 into which water whose temperature is raised in the heat exchanger 20 is introduced, and generated in the heater core 10 In a vehicle heating apparatus consisting of a fan 12 for introducing heat into the room; The heat exchanger (20) is a gas injection nozzle (34) therein, a spark plug (36) in front of the gas injection nozzle (34) and the heat exchanger housing (22) is drilled in the mixed air for introducing mixed air A gas combustion unit 30 having an injection hole 38 therein; A water input part 40 provided with a water input pipe 41 and a water discharge pipe 42, respectively; The heat transfer tube 50 is installed between the gas combustion unit 30 and the water input unit 40.

    Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
    1 is a schematic view showing a conventional auxiliary heater, Figure 2 is a cross-sectional view showing a heat exchanger of the present invention, Figure 3 is a cross-sectional view taken along line A-A of FIG.
    As shown in FIG. 1, a conventional auxiliary heater includes a gas tank 4 for supplying gas to the engine 2, and a heat exchanger 20 connected with the gas tank 4 to increase the temperature of water. And a pump 8 which circulates and simultaneously circulates the cooling water of the engine 2 to the heat exchanger 20, and a heater core 10 into which water whose temperature is raised in the heat exchanger 20 is introduced. It is composed of a fan 12 for introducing the heat generated in the (10) into the room.
    The heat exchanger 20 has a gas combustion unit 30 and a water input unit 40 formed therein, and a heat transfer tube 50 is installed between the gas combustion unit 30 and the water input unit 40. .
    The gas combustion unit 30 has a gas injection nozzle 34 connected to the gas tank 32 on one side, a spark plug 36 connected to an ignite part (not shown) in front of the gas injection nozzle 34, and A mixed air inlet 38 is drilled in the heat exchanger housing 22 to introduce the mixed air.
    In addition, the water inlet 40 is provided with a water inlet tube 41 installed in the heat exchanger housing 22 and a water discharge tube 42 for supplying hot water to the heater core 10.
    In addition, the heat transfer pipe 50 installed between the gas combustion unit 30 and the water input unit 40 includes a plurality of protrusion plates 52 and protrusion pins 54 on the outer diameter in order to maximize heat transfer to the inner diameter. It is formed respectively.
    Referring to the operation relationship of the heat exchanger 20 configured as described above are as follows.
    The gas is injected from the gas injection nozzle 34 connected to the gas tank 32, and the injected gas is ignited by the ignition plug 36 and combusted. Therefore, a flame is generated in the gas combustion unit 30 as described above, and the flame collides with the protruding plate 52 provided at the inner diameter of the heat transfer tube 50. Thereafter, the heat generated in the flame is discharged to the water inlet 40 through the protruding pins 54 of the heat transfer tube 50.
    Therefore, the water introduced from the engine 2 becomes hot while passing through the heat exchanger 20, and then flows into the heater core 10 so that warmth flows into the vehicle interior due to the operation of the fan 12.
    As described above, the present invention has an effect of expanding the heating portion of the water flowing into the auxiliary heater from the engine to improve the efficiency of the auxiliary heater.
    Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.
    Therefore, the true technical protection scope of the present invention should be determined only by the scope of the attached utility model registration request.
