Description

다중 증발기를 가진 열교환기의 솔레노이드밸브 {SOLENOID VALVE OF HEAT EXCHANGER WITH MULTI EVAPORATOR}Solenoid valve of heat exchanger with multiple evaporators {SOLENOID VALVE OF HEAT EXCHANGER WITH MULTI EVAPORATOR}

본 발명은 하나의 압축기에 콘덴서를 연결설치하고 이에 다중의 증발기를 연결설치하며, 상기 콘덴서와 증발기들의 사이에 냉매 공급을 위하여 솔레노이드밸브를구비하도록 한 열교환기에 있어서, 상기 솔레노이드밸브의 작동시 솔레노이드밸브의 실린더내에서 작동하는 플런저의 접촉 소음과 진동을 방지할 수 있도록 방음,방진수단을 구비하고 상기 솔레노이드밸브의 작동을 원활하게 할 수 있도록 한 다중 증발기를 가진 열교환기의 솔레노이드밸브에 관한 것이다.The present invention connects and installs a condenser in one compressor, and connects a plurality of evaporators, and in the heat exchanger having a solenoid valve for supply of refrigerant between the condenser and the evaporators, the solenoid valve during operation of the solenoid valve. The present invention relates to a solenoid valve of a heat exchanger having multiple evaporators provided with soundproofing and dustproof means to prevent contact noise and vibration of a plunger operating in a cylinder of the pump and to facilitate operation of the solenoid valve.

종래 일반적인 차량의 내부에는 냉방을 위하여 냉방장치인 에어컨 시스템을 구비하고 있으며, 이 에어컨 시스템은 증발기와 콘덴서 및 압축기로 구성되어 있고 상기 콘덴서는 응축작용을 하면서 외부로 열을 방출하도록 하고, 압축기에 의하여 압축된 냉매가 상기 콘덴서를 거쳐 증발기 유닛내로 흡인되며 이 흡인된 냉매가 외부 공기의 열을 흡수하면서 증발작용을 하여 공기를 저온화시키고 이 저온화된 공기를 블로어를 이용하여 차량의 실내로 공급하도록 구성되어 있었다.Conventionally, the inside of a vehicle is provided with an air conditioning system that is a cooling device for cooling, the air conditioning system is composed of an evaporator, a condenser and a compressor, the condenser is to discharge heat to the outside while condensing, by a compressor Compressed refrigerant is sucked into the evaporator unit through the condenser, and the sucked refrigerant absorbs heat from the outside air to evaporate to lower the air and supply the lowered air to the interior of the vehicle by using a blower. It was composed.

또한, 상기 냉방효율을 향상시키기 위하여 하나의 압축기에 하나의 콘덴서나 2중의 콘덴서를 설치하고 이 콘덴서들에는 리시버 드라이어와 솔레노이드밸브를 연결하며 이 솔레노이드밸브에는 전후방용으로 구성된 다중의 증발기들을 연결설치하고, 상기 압축기에서 압축된 냉매가 상기 콘덴서와, 리시버 드라이어 및 솔레노이드밸브를 거쳐 상기 다중으로 구성된 증발기들에 선택적으로 공급되면서 열교환작용을 하도록 구성하고 있었다.In addition, in order to improve the cooling efficiency, a single condenser or a double condenser is installed in one compressor, and a receiver dryer and a solenoid valve are connected to the condenser, and a plurality of evaporators configured for front and rear are connected to the condenser. The refrigerant compressed in the compressor was selectively supplied to the multiple evaporators via the condenser, the receiver dryer, and the solenoid valve, thereby performing heat exchange.

그러나, 상기와 같은 냉방사이클에 있어서, 상기 증발기들은 필요에 따라 어느 한쪽의 증발기만 작동하게 되는데, 상기 어느 한쪽의 증발기가 작동할 경우 나머지 증발기에서는 상기 고온,고압의 냉매가 그대로 있기 때문에 이 증발기에서 어는현상인 아이싱현상이 발생되고 있으며, 이 아이싱현상에 의하여 압축기로 복귀되는냉매가 원활하게 복귀되지 못하게 되고 상기 압축기에서 액압현상이 발생되어 이 액압에 의한 냉매관이나 상기 압축기의 파손등이 발생되기 때문에 상기 증발기들로 냉매를 선택적으로 공급하는 솔레노이드밸브의 작동은 매우 중요하게 된다.However, in the cooling cycle as described above, the evaporators operate only one of the evaporators as needed. When the one of the evaporators is operated, the high-temperature, high-pressure refrigerant is left in the other evaporators. The icing phenomenon, which is a freezing phenomenon, is generated, and the refrigerant returned to the compressor cannot be smoothly returned, and a hydraulic phenomenon occurs in the compressor, causing damage to the refrigerant pipe or the compressor due to the hydraulic pressure. Therefore, the operation of the solenoid valve for selectively supplying the refrigerant to the evaporators is very important.

한편, 상기와 같이 작동되는 종래의 솔레노이드밸브는 도 1에서와 같이 입구(102)와 출구(103)가 형성된 밸브몸체(101)에 코일(105)이 권선된 실린더(104)를 설치하고 상기 실린더(104)의 내부에는 스프링(107)이 개재되는 상태로 플런저(106)를 설치하여 구성되어 있었으며, 상기 코일(105)에 전원이 인가되면, 자기력이 발생되어 상기 플런저(106)가 스프링(107)을 누르면서 작동갭(108)내로 이동하여 상기 입구(102)와 출구(103)를 개방시키게 되고 상기 코일(105)에 인가되는 전원을 차단시키게 되면, 상기 스프링(107)의 탄발력에 의하여 플런저(106)가 복귀되면서 상기 입구(102)와 출구(103)를 폐쇄시켜 냉매의 흐름을 차단하도록 구성되어 있었다.On the other hand, the conventional solenoid valve operated as described above is installed in the valve body 101, the coil 104 is wound on the valve body 101, the inlet 102 and the outlet 103 is formed as shown in Figure 1 and the cylinder Inside the 104, a plunger 106 was provided with a spring 107 interposed therebetween. When power is applied to the coil 105, a magnetic force is generated to cause the plunger 106 to spring 107. When moving into the working gap 108 to open the inlet 102 and the outlet 103 to cut off the power applied to the coil 105 while pressing the plunger by the spring force of the spring 107 As 106 is returned, the inlet 102 and the outlet 103 are closed to block the flow of the refrigerant.

그러나, 상기와 같은 종래의 솔레노이드밸브는 상기 플런저(106)가 실린더(104)내에서 작동될 때 상기 스프링(107)의 탄발력과 코일(105)의 자기력에 의하여 충격을 받게 되며, 이 충격에 의하여 진동과 함께 소음이 발생하게 되는 점 등의 문제점이 있었다.However, the conventional solenoid valve as described above is shocked by the elastic force of the spring 107 and the magnetic force of the coil 105 when the plunger 106 is operated in the cylinder 104. There was a problem such that noise is generated along with the vibration.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 본 발명은 하나의 압축기에 콘덴서를 연결설치하고 이에 다중의 증발기를 연결설치하며, 상기 콘덴서와 증발기들의 사이에 냉매 공급을 위하여 솔레노이드밸브를 구비하도록 한 열교환기에 있어서, 상기 솔레노이드밸브의 작동시 솔레노이드밸브의 실린더내에서 작동하는 플런저의 접촉 소음과 진동을 방지할 수 있도록 방음,방진수단을 구비하고 상기 솔레노이드밸브의 작동을 원활하게 할 수 있도록 한 다중 증발기를 가진 열교환기의 솔레노이드밸브를 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned problems in the related art. The present invention provides a condenser connected to one compressor and a plurality of evaporators connected thereto, and a solenoid valve for supplying a refrigerant between the condenser and the evaporators. In the heat exchanger having a, the soundproof, dustproof means to prevent the contact noise and vibration of the plunger operating in the cylinder of the solenoid valve during operation of the solenoid valve can be smooth and the operation of the solenoid valve It is intended to provide a solenoid valve of a heat exchanger having a multiple evaporator so that it will be described in detail below based on the accompanying drawings.
