열교환기용 필터 유닛{FILTER UNIT FOR HEAT EXCHANGER}Filter unit for heat exchanger {FILTER UNIT FOR HEAT EXCHANGER}

본 발명은 열교환기용 필터 유닛에 관한 것이다.The present invention relates to a filter unit for a heat exchanger.

종래의 열교환기용 필터 유닛으로서, 예를 들면 특허문헌1에 기재되어 있는 열교환기용 필터 유닛이 알려져 있다. 이 특허문헌1에 기재되어 있는 열교환기용 필터 유닛은 통기성 및 투습성이 있는 재료로 만들어진 평평한 라이너와 마찬가지로 통기성 및 투습성이 있는 재료로 만들어진 파형판(corrugated sheet)을 접착제를 이용하여 접합한 한쪽면이 골판지(corrugated board)형상인 필터를 상하 방향으로 인접하는 필터의 골 방향이 서로 직교하는 방향을 향하도록 다수매 적층해서 이루어지는 것이다.As a conventional heat exchanger filter unit, the heat exchanger filter unit described in patent document 1 is known, for example. The filter unit for heat exchanger described in this patent document 1 is a corrugated sheet bonded to a corrugated sheet made of a breathable and moisture-permeable material with an adhesive like a flat liner made of a breathable and moisture-permeable material. A corrugated board is formed by stacking a plurality of filters so that the valleys of adjacent filters in the vertical direction face the direction perpendicular to each other.

(특허문헌1) 일본 특허공개 2005-201502호 공보(Patent Document 1) Japanese Patent Application Laid-Open No. 2005-201502

상기 특허문헌1에 기재된 열교환기용 필터 유닛의 경우, 일반적으로는 라이너나 파형판은 평평한 재료로 만들어져 있으며, 특히 공기와의 접촉이 많은 파형판의 표면이 평활하면 공기가 라이너와 파형판으로 형성되는 유로내를 거의 스트레이트 상태로 흐르게 되어 열교환 효율을 향상시키는 데에 한계가 있었다.In the case of the filter unit for heat exchanger described in Patent Document 1, generally, the liner or corrugated plate is made of a flat material, and in particular, when the surface of the corrugated plate having a lot of contact with air is smooth, air is formed into the liner and corrugated plate. There was a limit in improving heat exchange efficiency because the passage flowed almost straight.

본 발명의 목적은, 이러한 과제를 해결하는 것으로, 라이너와 파형판으로 형성되는 유로내에 있어서의 공기의 통과 시간을 길게 할 수 있어 열교환 효율의 향상을 꾀할 수 있는 열교환기용 필터 유닛을 제공하는 데에 있다.SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem, and to provide a filter unit for a heat exchanger capable of lengthening the passage time of air in a flow path formed of a liner and a corrugated plate and improving heat exchange efficiency. have.

본 발명의 청구항1에 기재된 열교환기용 필터 유닛은 투습성이 있는 종이로 만들어진 라이너와, 투습성이 있는 크레이프 페이퍼(crepe paper)로 만들어진 파형판을 접착제를 이용하여 접합한 한쪽면이 골판지형상인 필터를 상하 방향으로 인접하는 필터의 골 방향이 서로 직교하는 방향을 향하도록 다수매 적층하고 접착해서 이루어지는 것을 특징으로 한다.The filter unit for a heat exchanger according to claim 1 of the present invention has a filter having a corrugated cardboard shape on one side of which a liner made of moisture-permeable paper and a corrugated plate made of moisture-permeable crepe paper are bonded with an adhesive. A plurality of sheets are laminated and bonded so that the valley directions of the filters adjacent to each other face in a direction orthogonal to each other.

청구항2에 기재된 열교환기용 필터 유닛은 라이너도 크레이프 페이퍼로 만들어져 있는 것을 특징으로 한다.The filter unit for heat exchangers of Claim 2 is also a liner also made from crepe paper, It is characterized by the above-mentioned.

(발명의 효과)(Effects of the Invention)

이상과 같이, 본 발명의 열교환기용 필터 유닛은 크레이프 페이퍼로 만들어진 파형판의 주름의 요철에 의해 라이너와 파형판으로 형성되는 유로내의 기류가 층류(層流)가 아니라 난류(亂流)로 되고, 또 파형판의 주름의 요철에 의해 파형판과의 공기의 접촉 면적이 커져 인접하는 필터 사이에 존재하는 라이너를 사이에 두 고 행해지는 유체간의 열교환 효율을 향상시킬 수 있다. 또한 라이너도 크레이프 페이퍼로 만들어져 있으면 열교환 효율을 더욱 향상시킬 수 있다.As described above, in the heat exchanger filter unit of the present invention, the air flow in the flow path formed by the liner and the corrugated plate is turbulent rather than the laminar flow due to the unevenness of the corrugated plate made of the crepe paper. In addition, the corrugation of the corrugated plate causes an increase in the contact area of air with the corrugated plate, thereby improving the heat exchange efficiency between the fluids performed between liners existing between adjacent filters. The liner can also be made of crepe paper to further improve heat exchange efficiency.

이하, 본 발명의 일실시형태를 도 1∼도 4를 이용하여 구체적으로 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described concretely using FIGS.

도면에 있어서, 1은 투습성이 있는 평평한 종이로 만들어진 라이너(2)와, 마찬가지로 투습성이 있는 크레이프 페이퍼(주름이 있는 종이)로 만들어진 파형판(3)을 접착제를 이용하여 접합한 한쪽면이 골판지형상인 필터이며, 상기 라이너(2)를 하측에 위치시킨 필터(1)를 상하 방향으로 인접하는 필터(1)의 골 방향이 서로 직교하는 방향을 향하도록 다수매 적층하고 접착해서 열교환기용 필터 유닛을 제작하고 있다. 또, 최하부에 위치하는 필터(1)의 하측에는 그 필터(1)의 상기 라이너(2)가 존재하는 것이지만, 최상부에 위치하는 필터(1)의 파형판(3)의 상측에는 라이너가 존재하지 않으므로, 상기 라이너(2)와 같은 재료로 만들어진 라이너(4)를 접합시키고 있다.In the drawing, 1 is a liner 2 made of a moisture-permeable flat paper, and a corrugated sheet 3 made of a moisture-permeable crepe paper (wrinkled paper) is bonded to one side using an adhesive. The filter 1 for the heat exchanger is formed by stacking and adhering a plurality of filters 1 having the liner 2 positioned at the lower side thereof so that the valleys of the adjacent filters 1 are perpendicular to each other in a direction perpendicular to each other. I produce it. Moreover, although the said liner 2 of the filter 1 exists in the lower side of the filter 1 located in the lowest part, the liner does not exist in the upper side of the corrugated plate 3 of the filter 1 located in the upper part. Therefore, the liner 4 made of the same material as the liner 2 is bonded.

상기 구성에 있어서, 크레이프 페이퍼로 만들어진 파형판(3)의 주름의 요철에 의해 라이너(2)와 파형판(3)으로 형성되는 유로내의 기류가 층류가 아니라 난류로 되고, 또 파형판(3)의 주름의 요철에 의해 파형판(3)와의 공기의 접촉 면적이 커져 인접하는 필터(1) 사이에 존재하는 라이너(2)를 사이에 두고 행해지는 유체간의 열교환 효율을 향상시킬 수 있다.In the above configuration, the airflow in the flow path formed by the liner 2 and the corrugated plate 3 becomes turbulent rather than laminar by the unevenness of the corrugated plate 3 made of crepe paper, and the corrugated plate 3 Due to the unevenness of the wrinkles, the contact area of the air with the corrugated plate 3 is increased, and the heat exchange efficiency between the fluids performed between the liners 2 existing between the adjacent filters 1 can be improved.

또, 도면에 나타내는 실시형태에서는 라이너(2,4)는 평평한 종이로 만들어져 있지만, 이 라이너(2,4)를 파형판(3)과 마찬가지로 크레이프 페이퍼로 만들도록 해 도 좋다.In the embodiment shown in the drawing, the liners 2 and 4 are made of flat paper, but the liners 2 and 4 may be made of crepe paper similarly to the corrugated plate 3.
