Description
본 고안은 차량의 엔진냉각용 라디에이터와 공조시스템의 응축기를 일체형으로 구성한 열교환기에 관한 것으로, 차량의 엔진냉각용 라디에이터와 공조시스템의 응축 열교환기에 각각 설치되는 열교환기 튜브시트를 일체형으로 제작하여 단일의 열교환기에 적용함으로써 차량의 엔진냉각용 열교환 작용과 공조시스템의 응축 열교환 작용 기능을 동시에 수행 할 수 있어 경량화에 따른 차량연비 향상과 제조원가 절감을 도모할 수 있는 차량의 엔진냉각용 라디에이터와 공조시스템의 응축기를 일체형으로 구성한 열교환기에 관한 것이다.The present invention relates to a heat exchanger composed of an engine cooling radiator of a vehicle and a condenser of an air conditioning system in one unit, and a heat exchanger tube sheet installed respectively for an engine cooling radiator of the vehicle and a condensation heat exchanger of an air conditioning system is manufactured in a single unit. Applied to the heat exchanger, the engine cooling heat exchanger of the vehicle and the condensation heat exchanger function of the air conditioning system can be performed at the same time, thereby improving the vehicle fuel efficiency and manufacturing cost due to light weight, and the engine cooling radiator of the vehicle and the condenser of the air conditioning system It relates to a heat exchanger that is integrally configured with.
최근 자동차 산업분야에서 연비절감과 대기환경오염 문제 등의 개선을 목적으로 범정부차원에서 차량부품의 경량화를 통한 에너지 절감운동이 시도되고 있는 바, 이러한 추세에 부흥하기 위해 차량의 핵심부품인 엔진성능의 향상과 차량의 전체부품의 고효율화 및 경량화 방안이 중점적으로 논의·연구되고 있다.Recently, in the automobile industry, energy-saving movements have been attempted by reducing the weight of vehicle parts at the government level for the purpose of reducing fuel consumption and air pollution. Improvement and weight reduction of all parts of the vehicle are being discussed and researched.
종래의 일반적인 차량의 엔진냉각용 라디에이터의 열교환기와 공조시스템의 평행순환형 응축 열교환기는 서로 독립된 기술 구성 및 기능을 담당하고 있었다.The heat exchanger of an engine cooling radiator of a conventional general vehicle and the parallel circulation type condensation heat exchanger of an air conditioning system were in charge of independent technology configurations and functions.
엔진냉각용 라디에이터는 차량 엔진의 실린더 주위에 냉각수를 흐르게 하여 고온의 엔진을 냉각시켜 피스톤, 밸브 등의 과열로 인한 고착을 방지하고 윤활유의 온도를 일정하게 유지시켜 실린더 내부의 마찰 및 마모를 방지하기 위한 장치이며, 차량의 공조시스템의 구성요소인 응축열교환기는 압축기에서 토출된 고온고압의 냉매를 외기와의 강제대류를 통하여 응축 열교환 시키는 장치로서, 이 두 장치는 차량의 엔진실 내부에 각각 분리되어 장착되어 있으므로 장착공간의 확보가 어렵고동일 공간상에 중복 장착되므로써 생산성 저하 및 제조공정의 증가, 엔진냉각용 라디에이터용 팬과 응축열교환기용 팬간의 상호 유동방해로 인한 열전달 성능 저하와 소음발생 등의 문제점이 있어왔다.Engine cooling radiator cools high temperature engine by flowing coolant around cylinder of vehicle engine to prevent seizure due to overheating of piston, valve, etc., and keeps temperature of lubricating oil to prevent friction and wear inside cylinder The condensation heat exchanger, which is a component of the vehicle air conditioning system, is a device for condensation heat exchange between the high temperature and high pressure refrigerant discharged from the compressor through forced convection with the outside air. It is difficult to secure the installation space because it is installed in the same space, and the problems such as reduced productivity and increase of manufacturing process, deterioration of heat transfer performance and noise generation due to mutual flow disturbance between fan for engine cooling radiator and fan for condensation heat exchanger. This has been.
이러한 단점을 해결하기 위한 방편으로 고정구를 이용하여 응축기와 라디에이터를 단순히 하나로 결합시키는 모듈화를 통하여 제조공정의 단축과 작업성 향상 및 엔진실 내부의 장착공간의 최소화를 꾀한 구조도 있었으나, 이는 체결용 고정구 수의 증가로 인하여 모듈화된 총 중량이 증가되어 연비가 좋지 않은 단점이 있었고, 이 모듈화를 통하여 장착된 응축기용 팬과 라디에이터용 팬 상호간의 유동간섭문제는 여전히 잔존해 있어 성능의 저하를 초래하는 문제점이 있었다.As a way to solve these shortcomings, there was also a structure that shortened the manufacturing process, improved workability, and minimized the mounting space inside the engine compartment by modularizing the condenser and the radiator by simply using a fastener to combine them into one. Due to the increase in the number of modules, the total weight of the module was increased, leading to poor fuel economy.The problem of flow interference between the condenser fan and the radiator fan still remained due to this modularization, resulting in a decrease in performance. There was this.
본 고안은 상기와 같은 제반 문제점들을 해결하기 위하여 안출된 것으로, 차량의 엔진냉각용 라디에이터와 공조시스템의 응축 열교환기에 각각 설치되는 열교환기 튜브시트를 일체형으로 제작하여 단일의 열교환기에 적용함으로써 차량의 엔진냉각용 열교환 작용과 공조시스템의 응축 열교환 작용 기능을 동시에 수행 할 수 있어 경량화에 따른 차량연비 향상과 제조원가 절감을 도모할 수 있는 차량의 엔진냉각용 라디에이터와 공조시스템의 응축기를 일체형으로 구성한 열교환기를 제공함을 그 목적으로 하고 있다.The present invention has been devised to solve the above problems, the heat exchanger tube sheets respectively installed in the engine cooling radiator of the vehicle and the condensation heat exchanger of the air conditioning system integrally manufactured and applied to a single heat exchanger engine of the vehicle It can perform heat exchange action for cooling and condensation heat exchange function of air conditioning system at the same time, thus providing heat exchanger that is integrated with engine cooling radiator of car and condenser of air conditioning system that can improve vehicle fuel efficiency and reduce manufacturing cost due to light weight. For that purpose.

After mounting between the fins (5a) (5b) or the integral fins (5c) by mounting the reinforcing bar (8) by the integral heat exchanger is made.
상기에서 도 2a 에 도시한 바와 같이 응축 열교환부(1)와 엔진냉각용 라디에이터부(2)에 각각 장착되어 열교환 기능을 담당하도록 분리형 핀(5a)(5b)을 구성할 수도 있고, 다른 실시예로서 도 2b 에 도시한 바와 같이 일체로 장착되어 열교환 기능을 동시에 수행할 수 있도록 일체형 핀(5c)을 구성할 수 도 있다.As shown in FIG. 2A, separate fins 5a and 5b may be configured to be mounted on the condensation heat exchanger 1 and the radiator 2 for engine cooling, respectively, and to perform a heat exchange function. As shown in FIG. 2B, the integrated fins 5c may be integrally mounted so that the heat exchange function may be simultaneously performed.
일체형 튜브시트(6)는 냉각수가 유입(화살표 A 방향)되어 엔진을 냉각시키는 라디에이터부(2) 기능을 수행하는 튜브와 냉매가 유입(화살표 B 방향)되어 응축 열교환시키는 응축 열교환부(1) 기능을 담당하는 튜브로 이루어지며, 도 3a 는 응축 열교환부(1)는 짧게 라디에이터부(2)는 길게 구성한 것이며, 도 3b 는 응축 열교환부(1)와 라디에이터부(1)의 전체길이를 동일하게 구성시킨 것이다.The integrated tube sheet 6 has a condensation heat exchanger 1 functioning to condense and heat exchange a tube having a radiator portion 2 functioning as a coolant flows in the arrow A direction to cool the engine and a refrigerant flows in the arrow B direction. 3a is a condensation heat exchange part 1 is short, the radiator part 2 is configured long, Figure 3b is the same as the overall length of the condensation heat exchange part 1 and the radiator part 1 It is made up.
