자동차용 냉풍발생장치{Cold wind apparatus for the car}Cold wind apparatus for the car

본 발명은 자동차용 냉풍발생장치에 관한 것으로서, 더욱 상세하게는 자동차의 주행시 발생되는 바람으로 열교환기를 냉각시키고 또한 열전소자의 냉각부로 열교환기를 냉각시켜 상기 열교환기를 순환하는 냉매체의 온도를 외기보다 낮춰 줌으로써, 자동차 실내공기가 상기 열교환기에서 공냉되어 실내가 상온 20℃ 내외로 쾌적하게 유지되고 과냉방에 따른 연료소모를 줄일 수 있는 에너지 절약형의 자동차용 냉풍발생장치에 관한 것이다.The present invention relates to a cold air generating device for automobiles, and more particularly, to cool the heat exchanger with the wind generated during driving of the vehicle, and to cool the heat exchanger with the cooling unit of the thermoelectric element to lower the temperature of the refrigerant body circulating the heat exchanger than outside air. By providing air, the indoor air of the automobile is air-cooled in the heat exchanger, and the room is comfortably maintained at about 20 ° C at room temperature, and relates to an energy-saving automotive cold wind generator that can reduce fuel consumption due to overcooling.

일반적으로 자동차는 냉동사이클장치를 이용하여 실내를 냉방하고 있는데, 냉동사이클장치란 냉매를 압축, 응축, 팽창 및 증발시키고 증발과정에서 실내 온도를 낮춰 실내가 냉방되도록 하는 장치이다.In general, a vehicle uses a refrigeration cycle device to cool an interior. A refrigeration cycle device is a device that compresses, condenses, expands, and evaporates a refrigerant and lowers the indoor temperature in an evaporation process so that the interior is cooled.

그러나 이러한 냉동사이클은 장치의 구성이 복잡하여 제작 및 구입비가 증가되며, 에너지를 많이 필요로하므로 자동차의 연료소모량이 증가되는 단점이 있었다. 그리고 냉풍 온도가 낮기 때문에 자동차 실내를 밀폐상태에서 장시간 가동할 경우 냉방병에 걸릴 위험이 있는 등의 문제점이 있었다.However, such a refrigeration cycle has a disadvantage in that the composition of the device is complicated, the production and purchase cost is increased, and the energy consumption of the vehicle is increased because it requires a lot of energy. In addition, since the cold wind temperature is low, there is a problem that there is a risk of getting a cooling bottle if the car interior is operated for a long time in a sealed state.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 자동차의 주행시 발생되는 바람으로 열교환기를 냉각시키고 또한 열전소자의 냉각부로 열교환기를 냉각시켜 상기 열교환기를 순환하는 냉매체의 온도를 외기보다 낮춰 줌으로써, 자동차 실내공기가 상기 열교환기에서 공냉되어 실내가 상온 20℃ 내외로 쾌적하게 유지되고 과냉방에 따른 연료소모를 줄일 수 있는 에너지 절약형의 자동차용 냉풍발생장치에 관한 것이다.The present invention was developed in view of the conventional problems, and an object of the present invention is to cool the heat exchanger with the wind generated during driving of the vehicle, and also to cool the heat exchanger with the cooling unit of the thermoelectric element to circulate the temperature of the refrigerant body circulating the heat exchanger. By lowering, the indoor air of the automobile is air-cooled in the heat exchanger, and the room is comfortably maintained at around 20 ° C at room temperature, and relates to an energy-saving automotive cold wind generator that can reduce fuel consumption due to overcooling.

이를 위하여 본 발명은 자동차 지붕의 외부에는 외기가 통과하는 외기입구 및 외기출구가 형성된 케이스가 구비되고, 상기 자동차 지붕에는 상기 케이스에 덮이도록 실내 공기가 순환되는 입,출구가 형성되며, 상기 케이스 내부에는 상기 입,출구 및 상기 외기입,출구를 구획하여 냉매체가 순환되는 실내,외 열교환기가 각각 다른 공간에 설치되도록 실내 연통부 및 실외 연통부를 만드는 분리판이 구비되고, 상기 분리판에는 상기 냉매체가 순환되는 냉매체관을 냉각시키는 열전소자가 구비되며, 상기 분리판의 전방에는 자동차의 주행시 상기 외기입구로 유입되어 상기 실외 열교환기 및 열전소자를 냉각시키는 바람의 일부를 상기 실내 연통부로 유도하여 상기 열전소자 및 실내 열교환기에서 공냉되고 실내로 순환되면서 냉풍이 발생되도록 하는 통로가 형성된 특징이 있다.To this end, the present invention is provided with a case formed with an outside air inlet and an outside air outlet through which outside air passes, and an inlet and an outlet through which indoor air is circulated so as to be covered by the case. The separator is provided with a partition plate which divides the inlet, the outlet, and the external inlet and the outlet to form an indoor communication part and an outdoor communication part so that the indoor and outdoor heat exchangers, through which the refrigerant body is circulated, are installed in different spaces. The thermoelectric element is provided to cool the refrigerant body tube, and the front of the separator plate is introduced into the outside air inlet when the vehicle is driven to guide a part of the wind to cool the outdoor heat exchanger and the thermoelectric element to the indoor communication unit. And air to cool the air in the room heat exchanger and circulate to the room to generate cold air It is characterized in that formed.

본 발명에 따르면 자동차의 주행시 발생되는 바람을 열교환기로 유도하여 상 기 열교환기 내부로 순환되는 냉매체를 냉각시킴으로써, 공냉팬을 가동하지 않아도 되므로 에너지를 절약할 수 있다. 또한 열교환기의 부족한 냉열원은 열전소자의 냉각부에서 취득하면 되므로 상기 열교환기를 순환하는 냉매체를 실외보다 낮출 수 있다.According to the present invention, by driving the wind generated during the driving of the car to the heat exchanger to cool the refrigerant circulated into the heat exchanger, it is not necessary to operate the air cooling fan can save energy. In addition, since the insufficient heat source of the heat exchanger may be obtained from the cooling unit of the thermoelectric element, the refrigerant body circulating the heat exchanger may be lower than that of the outdoor.

열전소자(熱電素子, thermoeletric element)는 전기저항의 온도변화를 이용한 소자로써, 온도차에 의해 기전력이 발생하는 현상을 이용한 소자와, 전류에 의해 열의 흡수가 생기는 현상을 이용한 소자로써, 반도체를 이용한 방식이므로 전력소모를 줄일 수 있는 이점이 있으며, 냉매체관이 열전소자의 냉각부에 밀착되어 빠르게 냉각되므로 열교환효율이 향상되는 이점이 있다.A thermoeletric element is a device using a temperature change of an electrical resistance, a device using a phenomenon in which electromotive force is generated by a temperature difference, and a device using a phenomenon in which heat is absorbed by a current. Therefore, there is an advantage that can reduce the power consumption, the refrigerant pipe is in close contact with the cooling portion of the thermoelectric element is cooled quickly, there is an advantage that the heat exchange efficiency is improved.

또한 상기 열교환기는 실외 및 실내 열교환기로 분리 구성한 뒤 실외 열교환기는 자동차의 주행시 발생되는 외기를 유도하여 자연풍으로 냉각시키고, 일부 외기를 상기 실내 열교환기로 유도하여 실내공기와 함께 공냉되도록 하면 밀폐된 실내 공기를 쾌적하게 만들 수 있다.In addition, the heat exchanger is configured to separate the outdoor and indoor heat exchanger and then the outdoor heat exchanger guides the outdoor air generated during driving of the car to cool the natural wind, and guides some outdoor air to the indoor heat exchanger to allow air to be cooled together with the indoor air. I can make it comfortable.

그리고 상기 실외 및 실내 열교환기의 사이에 열전소자를 설치하여 이들을 연결하는 냉매체관이 열전소자에서 적극적으로 냉각되도록 하면 냉매체의 온도를 항상 낮게 유지시킬 수 있으므로 자동차가 정차되어 외기를 도입할 수 없더라도 실내온도를 상온 20℃ 내외로 유지시킬 수 있으므로 종래 냉동사이클장치를 가동시킬 때 보다 연료를 절약할 수 있으며, 과냉방에 따른 부작용도 해소할 수 있는 이점이 있다.In addition, if a thermoelectric element is installed between the outdoor and indoor heat exchanger to actively cool the refrigerant body tube connecting the thermoelectric element, the temperature of the refrigerant body can always be kept low, so even if the vehicle is stopped and the outside air cannot be introduced. Since the indoor temperature can be maintained at or below room temperature 20 ℃, it is possible to save fuel than when operating the conventional refrigeration cycle apparatus, there is an advantage that can eliminate the side effects due to overcooling.

The indoor air circulated to the outlets 11 and 12 is heat-exchanged, and the outdoor communication unit 21 is provided with an outdoor heat exchanger 31. The outside air inlet 24 is formed in front of the case 20, and the outside air outlet 25 is formed in the rear to cool the outdoor air while passing through the outdoor heat exchanger 31 while the vehicle is running.

상기 실내,외 열교환기(30)(31)에는 냉매체가 순환되는 냉매체관(33)으로 연결되며, 이들 열교환기(30)(31)는 팬코일유니트 형태로 얇은 알루미늄 박판이 무수히 많이 형성되어 열교환효율을 높이는 구조로 일반화된 것이다.The indoor and outdoor heat exchangers 30 and 31 are connected to a refrigerant body tube 33 through which a refrigerant body is circulated, and these heat exchangers 30 and 31 are formed of a myriad of thin aluminum sheets in the form of a fan coil unit to exchange heat. The structure is generalized to increase efficiency.

상기 분리판(23)에는 열전소자(40)가 설치된다. 상기 열전소자(40)는 방열핀(43)을 갖는 방열부(41) 및 냉각핀(44)을 갖는 냉각부(42)가 서로 맞대어진 구조로써, 일반화된 것이다. 이러한 열전소자(40)의 냉각부(42)는 실내 연통부(22)로 노출시키고, 방열부(41)는 실외 연통부(21)로 노출시킨다.The separator 23 is provided with a thermoelectric element 40. The thermoelectric element 40 has a structure in which the heat dissipation part 41 having the heat dissipation fins 43 and the cooling part 42 having the cooling fins 44 are opposed to each other. The cooling part 42 of the thermoelectric element 40 is exposed to the indoor communication part 22, and the heat dissipation part 41 is exposed to the outdoor communication part 21.

그리고 상기 분리판(23)의 전방에는 통로(26)가 형성되어 상기 실외 연통부(21)로 유입되는 외기의 일부가 상기 실내 연통부(22)로 유도되도록 한다. 상기 통로(26)로 유도되는 일부 외기는 상기 실내 열교환기(30) 및 열전소자(40)의 냉각 부(42)에서 실외보다 온도가 떨어진 뒤 출구(22)를 거처 실내로 순환되고 다시 입구(11)로 흡입되면서 상기 실내 열교환기(30)로 순환되는 구조이며, 이때 실내 공기는 대류작용으로 자연스럽게 순환되어 냉풍이 발생되고 자동차 실내는 상온 20℃ 내외로 외기가 일부 유입되어 쾌적한 상태로 된다.In addition, a passage 26 is formed in front of the separating plate 23 so that a part of the outside air flowing into the outdoor communication unit 21 is guided to the indoor communication unit 22. Some outside air guided to the passage 26 is circulated through the outlet 22 after the temperature is lower than the outside in the cooling unit 42 of the indoor heat exchanger 30 and the thermoelectric element 40, and then the inlet ( 11) is sucked into the indoor heat exchanger 30, the indoor air is naturally circulated by the convection action to generate cold air, and the interior of the car is in a pleasant state due to the inflow of some outside air at room temperature 20 ℃.

도 3은 본 발명 한 실시예의 냉풍발생장치용 열전소자의 사시도로써, 상기 열전소자(40)의 방열부(41) 및 냉각부(42)에 형성된 방열핀(43)과 냉각핀(44)은 바람의 방향과 나란하게 일렬로 다수개 세워진 박판의 형태이며, 특히 상기 냉각부(42)에는 상기 냉매체관(33)의 일부가 상기 냉각핀(44)을 피해 지그재그 형태로 배관되어 밀착된 구조를 갖는다. 따라서 상기 실내,외 열교환기(30)(31)로 순환되는 냉매체가 상기 냉각부(42)를 지나면서 냉각된다. 미설명부호 13 및 14는 입,출구(11)(12)에 설치된 필터이고, 32는 냉매체를 순환시키는 순환펌프이며, 50 및 51은 자동차의 정차시 실외 열교환기(31)의 방열 및 실내 열교환기(30)의 공냉을 위한 팬 및 모터이다.3 is a perspective view of a thermoelectric element for a cold air generating device according to an embodiment of the present invention, wherein the radiating fins 43 and the cooling fins 44 formed on the radiating portion 41 and the cooling portion 42 of the thermoelectric element 40 are winded. It is in the form of a plurality of thin plates lined up in parallel with the direction of, in particular, the cooling portion 42 has a structure in which a part of the coolant body pipe 33 is piped in a zigzag form avoiding the cooling fin 44 and in close contact. . Therefore, the refrigerant body circulated to the indoor and outdoor heat exchangers 30 and 31 is cooled while passing through the cooling unit 42. Reference numerals 13 and 14 are filters installed at the inlet and outlet 11 and 12, 32 are circulation pumps for circulating the refrigerant body, and 50 and 51 are heat dissipation and indoors of the outdoor heat exchanger 31 when the vehicle is stopped. Fan and motor for air cooling of the heat exchanger (30).

이처럼 구성된 본 발명 한 실시예의 동작과정은 다음과 같다.The operation process of the embodiment of the present invention configured as described above is as follows.

먼저 열전소자(40) 및 순환펌프(32)를 작동시키면 실내,외 열교환기(30)(31) 내부로 냉매체가 순환되고 이 과정에서 열전소자(40)를 거치면서 냉각된다. 이 상태에서 자동차가 주행되면 외기가 외기입구(24)를 거쳐 케이스(20) 내부로 유입된 뒤 실외 연통부(21)에 설치된 실외 열교환기(31)를 통과하는데, 상기 실외 열교환기(31)에는 냉매체관(33)이 배관되어 있으므로 냉매체는 바람에 의해 방열되어 냉각되고 상기 실내 열교환기로(30)로 향한다. 그리고 열전소자(40)의 방열부(41)는 외기에 의해 방열된다.First, when the thermoelectric element 40 and the circulation pump 32 are operated, the refrigerant body is circulated inside the heat exchanger 30 and 31 inside and outside, and is cooled while passing through the thermoelectric element 40 in this process. When the vehicle is driven in this state, the outside air flows into the case 20 through the outside air inlet 24 and then passes through the outdoor heat exchanger 31 installed in the outdoor communication unit 21. The outdoor heat exchanger 31 Since the refrigerant body pipe 33 is piped, the refrigerant body is radiated and cooled by the wind, and is directed to the indoor heat exchanger 30. The heat radiating portion 41 of the thermoelectric element 40 is radiated by outside air.

또한 상기 케이스(20) 내부로 유입된 외기의 일부는 통로(26)를 따라 실내 연통부(22)로 유도된 뒤 상기 열전소자(40)의 냉각부(42) 에서 냉각되고, 상기 실내 열교환기(30)에 배관된 냉매체관(33)을 순환하는 냉매체에 의해 추가로 냉각되어 냉풍으로 된 뒤 출구(12)를 따라 실내로 방출된다. 실내로 토출되는 냉풍은 대류작용에 의해 상기 입구(11)를 거쳐 상기 실내 연통부(22)로 순환되면서 외기와 혼합된 뒤 순환되는 과정을 반복한다. 따라서 실내공기는 외기가 도입되어 냉풍으로 변한 뒤 실내로 순환되는 구조로서 약 20℃ 내외로 선풍기 바람보다 시원하고 에어컨 바람보단 약하므로 과냉방이 방지되고 외기가 도입되므로 밀폐된 실내를 쾌적하게 유지시킨다.In addition, a portion of the outside air introduced into the case 20 is guided to the indoor communication unit 22 along the passage 26 and then cooled in the cooling unit 42 of the thermoelectric element 40, and the indoor heat exchanger. The refrigerant is further cooled by the refrigerant body circulating through the refrigerant body pipe 33 piped to 30 to become cold air and then discharged into the room along the outlet 12. Cold air discharged into the room is circulated through the inlet 11 through the inlet 11 to the indoor communication unit 22 by mixing with the outside air, and then circulated. Therefore, indoor air is circulated into the room after the outdoor air is introduced into the cold wind, which is cooler than the wind of the fan at around 20 ° C and weaker than the air conditioner wind, thus preventing overcooling and introducing the outdoor air to keep the airtight room comfortable.

또한 자동차가 정차중일 때는 상기 모터(51)로 팬(50)을 가동시켜 상기 실외 열교환기(31)를 강제로 냉각시키고 외기 일부를 상기 실내 열교환기(30)로 보내 실내 공기가 계속 순환되면서 냉풍이 발생되도록 한다.In addition, when the vehicle is stopped, the fan 50 is operated by the motor 51 to forcibly cool the outdoor heat exchanger 31 and send a part of the outside air to the indoor heat exchanger 30 to continuously circulate the indoor air. Let this occur.

도 4는 본 발명 다른 실시예의 냉풍발생장치의 단면도로써, 본 발명 한 실시예와 동일 구성을 갖는다. 단지 상기 케이스(20) 내부가 분리판(23)에 의해 실외 연통부(21)와 실내 연통부(22)로 완전 분리되어 외기가 실내 연통부(22)에 유입되지 않도록 차단한 것이다. 그리고 실내 연통부(22)에는 실내 공기를 순환시키는 순환팬(60) 및 모터(61)를 설치하여 실내 열교환기(30) 및 냉각부(42)에서 실내 공기가 냉각되어 냉풍으로 만들어 지도록 한 차이가 있다.4 is a cross-sectional view of a cold wind generating device according to another embodiment of the present invention, and has the same configuration as the embodiment of the present invention. Only the inside of the case 20 is completely separated into the outdoor communication unit 21 and the indoor communication unit 22 by the separator 23 to block outside air from entering the indoor communication unit 22. In addition, the indoor communication unit 22 is provided with a circulating fan 60 and a motor 61 for circulating the indoor air so that the indoor air is cooled in the indoor heat exchanger 30 and the cooling unit 42 to make cold air. There is.

또한 선택적으로 외기를 실내에 도입하여 쾌적하게 하기 위해 상기 분리 판(23)의 일부에 외기도입구멍(71)을 천공하고 이를 개폐기(70)로 개폐시키는 구성이 추가된다.In addition, in order to selectively introduce the outside air into the room and make it comfortable, a portion of the separation plate 23 is drilled into the air inlet hole 71 and is opened and closed by the switch 70.

이처럼 구성된 본 발명 다른 실시예의 냉풍발생장치는 외기를 이용하여 실내 공기를 순환시키는 구조가 아니고 송풍팬(60)을 이용하여 실내 공기를 강제적으로 순환시키는 구조이다. 따라서 외기 온도가 높은 지역에서 사용하면 효과적이다. 즉 외기를 실내로 순환시키다 보면 온도를 낮추기 위해 열전소자(40)를 계속 가동시켜야 되므로 필요열량이 많이 소모되는 본 발명 한 실시예의 단점을 보완할 수 있다.The cold wind generator according to another embodiment of the present invention configured as described above is not configured to circulate indoor air using external air, but to circulate forced indoor air using the blower fan 60. Therefore, it is effective to use in the area with high outside temperature. That is, when circulating the outside air indoors, the thermoelectric element 40 needs to be continuously operated to reduce the temperature, thereby compensating for the disadvantages of the embodiment of the present invention in which much heat is required.

또한 밀폐된 실내의 환기 목적으로 상기 개폐기(70)를 모터로 작동시키면 외기도입구멍(71)이 열리면서 외기가 제한적으로 실내 연통부(22)로 유도되어 실내로 순환되므로 필요에 따라 실내를 쾌적하게 만들 수 있다.In addition, when the switch 70 is operated by a motor for the purpose of enclosed indoor ventilation, the outdoor air inlet 71 is opened and the outdoor air is circulated to the indoor communication unit 22 and is circulated to the room to make the room comfortable as needed. I can make it.
