    Evaporator attachment / detachment structure of automobile cooling and heating system
    The present invention relates to a detachable structure of an evaporator of a car cooling and heating device, and in particular, by changing a detachable structure of an evaporator interposed between a heater and a blower of a car cooling and heating device to improve the A / S (After Service) property of the evaporator. It relates to an evaporator detachable structure of an automobile cooling and heating device.
    In general, an air conditioner / heater system of a vehicle refers to a device for providing a comfortable feeling to a person on board by maintaining an appropriate environment of temperature, humidity, and air according to various changes of surroundings. It is divided into a heater that maintains high temperature and an air-conditioner that maintains low temperature.
    Automobile heating devices are classified as follows according to their heat sources.
    ① Hot water type uses the engine's cooling water as a heat source. Most of small and medium-sized cars, including passenger cars, use this method, and a blower is installed in a small heater core, and a control device is installed therein. As a simple structure, the engine coolant circulates the heater core through a water valve installed in the pipe system, and the indoor cold air is circulated to the space of the heater core fin by a blower, and heat exchange is performed at that part, and the control panel is operated. Blower motor changeover switch, water valve opening / closing lever, internal / external air switching, defroster adjustment lever, and the like. Blower motor adjustment mainly controls the speed using a resistor.
    ② Exhaust type uses engine exhaust heat when cooling water cannot be used like an air-cooled engine and is rarely used at present.
    ③ Combustion type uses independent combustor and is mainly used in bus, microbus, special vehicle for extreme regions, and fuel is kerosene or diesel. There are two types of air heaters, one for heating the air directly, and one for heating the engine coolant and using a hot water heater. The hot water heating type requires a pre-heater device that preheats the engine coolant before starting the engine, so that the device is complicated, but the engine is excellent in startability and durability.
    On the other hand, the automotive air conditioner has its main functional parts distributed and assembled in a position suitable for operation, respectively, and connected therebetween by a rubber hose or a metal pipe to form a refrigerant circulation circuit. As a condenser and an evaporator, a compressor is usually driven by a V belt by an engine crankshaft pulley and intermittently driven by a magnetic clutch inside the compressor.
    ② The condenser is installed in front of the radiator. It cools the refrigerant by cooling fan and running wind to liquefy it.
    ③ The evaporator is installed in the cabin together with the expansion valve, and it is the part that causes the cooling action by absorbing the surrounding heat when the refrigerant evaporates. The parts of the insulation case, the duct, etc. surrounding the evaporator are collectively called a cooling unit.
    In addition, in the configuration of a vehicle cooling system, the air conditioning system is a thermal expansion valve system and a clutch cycling orifice tube system according to the type of valve for converting a liquid refrigerant of high temperature and high pressure into a gas refrigerant of low temperature and low pressure and a refrigerant amount control method of an evaporator. The thermal expansion valve (TXV) system is a thermal expansion device that senses the temperature of the evaporator outlet and adjusts the amount of refrigerant entering the evaporator from the expansion valve according to the temperature. The clutch cycling orifice tube (CCOT) system uses a fixed orifice tube instead of a thermal expansion valve type expansion valve, and the accumulator's clutch cycling pressure switch Reduces the refrigerant pressure in the accumulator It is a system to prevent the freezing of the evaporator by turning on and off the operation of the magnetic clutch of the compressor according to the height of this pressure.
    R-12, which is used in automotive air conditioners, is the most ideal material for refrigerants, but only Cl (chlorine) in the molecule of CFC (fluorinated carbon) destroys the ozone layer, destroying the ecosystem by introducing a large amount of ultraviolet light to the surface of the earth. As it turns out to be a material that causes global warming, it has come to regulate its use.
    Therefore, HFC-134a (Hydro Fluro Carbon) is currently being used as an alternative material.
