Description

냉동창고용 방열 문틀구조{The doorframe of protection against heat for cold storage warehouse}Heat Resistant Door Frame Structure for Freezers {The doorframe of protection against heat for cold storage warehouse}

본 발명은 냉동창고용 방열 문틀구조에 관한 것으로서, 더욱 상세히는 외부의 열이 냉동실내로 전도되거나 영하의 실내온도가 외부로 발산되는 것을 방지하기 위한 냉동창고용 방열 문틀구조에 관한 것이다.The present invention relates to a heat dissipation door frame structure for the freezer, and more particularly to a heat dissipation door frame structure for the freezer for preventing the outside heat is conducted into the freezer compartment or the room temperature below zero is released to the outside.

종래에는 도 1에서 도시된 바와 같이 방열문틀을 제작함에 있어 단열 패킹과 제상(除霜)열선(10)을 각각 필요한 부위에 이들을 내설 할 수 있도록 압출성형 된 합성수지제의 문틀(100) 일측에 내설홈(11)을 형성시키고 제상열선(10)을 구비시킨 다음 금속제의 커버(12)로 마감되게 하였다.Conventionally, in manufacturing the heat dissipation door frame as shown in FIG. 1, the heat-insulated packing and the defrost heating wire 10 are respectively formed on one side of the door frame 100 made of an extruded synthetic resin so as to be embedded in the required parts. The grooves 11 were formed and the defrost heating wires 10 were provided and then finished with a metal cover 12.

이렇게 제상열선을 구성시키는 것은 단열을 하기 위함인데 단열효과를 극대화시키려면 온도를 상승시켜야만 한다. 그러나 상기와 같이 구성을 시켰을 경우 열에 약한 합성수지제가 화재를 유발시키기 때문에 고온으로 유지시킬 수가 없어 방열 기능을 발휘하지 못했다.The defrost heating wire is configured to insulate, but the temperature must be raised to maximize the insulation effect. However, when the above configuration is made, synthetic resins, which are weak in heat, cause a fire and thus cannot be maintained at a high temperature, thereby failing to exhibit a heat dissipation function.

또한 현재까지 국내외에 사용되고 있는 방열문에는 패킹부분으로만 냉기를 차단하는 방식을 사용해 오고 있는 실정으로 실내온도와 실외온도차이가 많으면 많을수록 패킹부분에 단열효과가 떨어짐은 물론 방열문 패킹이 얼어붙어 방열문 외부에 물방울이 생기면서 물이 창고외부로 흘러내려 위생상 불결함을 가져오고 있다.In addition, heat dissipation doors that have been used at home and abroad have been used to block the cold air only by the packing part. As water droplets form on the outside of the doors, water flows out of the warehouse, bringing sanitary imperfections.

이에 본 발명에서는 상기와 같은 제반 문제점을 일소하기 위해 안출한 것으로서, 제상열선의 온도를 놓여 문틀 자체에서 수분을 증발시키고 패킹의 얼어붙는 상태를 방지하여 고온을 유지하면서도 화재발생이 없어 단열효과가 우수한 방열문틀 구조를 제공함에 주안점을 두고 그 기술적 과제로서 완성한 것이다.Therefore, the present invention has been devised to eliminate all the problems described above, by placing the temperature of the defrost heating wire to evaporate moisture in the door frame itself and prevent the freezing state of the packing to maintain a high temperature, but without the occurrence of fire excellent heat insulation effect The main objective is to provide a heat dissipation door frame structure, and the technical task was completed.

위 기술적 과제를 달성하기 위하여 본원에서는 첨부된 각 도면에 의거 상세히 설명하면 하기와 같다.In order to achieve the above technical problem, the present invention will be described in detail with reference to the accompanying drawings.

즉, 도 1은 종래 방열문틀의 내부구조를 도시한 단면도이고, 도 2는 본 발명의 바람직한 일실시예를 보인 단면도이며, 도 3은 본 발명의 바람직한 일실시예를 보인 일부 절개 사시도이고, 도 4는 본 발명의 요지가 적용된 문틀구조의 사용상태 예시도로서 본 발명의 냉동창고용 방열문틀구조에 대해 이하 구체적으로 살펴보면,That is, Figure 1 is a cross-sectional view showing the internal structure of a conventional heat dissipation door frame, Figure 2 is a cross-sectional view showing a preferred embodiment of the present invention, Figure 3 is a partially cut perspective view showing a preferred embodiment of the present invention, Figure 4 is an exemplary view illustrating a state of use of the door frame structure to which the gist of the present invention is applied.

도 2와 3에서 도시된 바와 같이 냉동창고용 방열문틀은 "⊂"형으로 구성된 문틀(100)의 외곽일측에 열전도도가 높고 주위 전체에 열을 발생시킬 수 있는 별도의 불연성재질의 단열수단(101)을 끼움 구성시킨 것이다.As shown in FIGS. 2 and 3, the heat dissipation door frame for a freezer warehouse has a high thermal conductivity on the outer side of the door frame 100 configured as a “⊂” type, and a separate non-combustible heat insulating means capable of generating heat in the entire surrounding ( 101) is fitted.

상기와 같이 구성되는 방열문틀의 문틀(100)은 전체가 "⊂"형으로 구성되고 일측에는 복수개의 걸림턱(21)이 구성됨과 동시에 그 내측에는 체결홈(22a)이 일측방향으로 형성된다.The door frame 100 of the heat dissipation door frame is configured as a "전체" type and a plurality of engaging jaw 21 on one side and at the same time the fastening groove 22a is formed in one side.

그리고 상기 단열수단(101)은 일측방에 문틀의 체결홈(22a)과 대응되는 체결홈(22)이 복수개 형성됨과 동시에 그 홈(22)의 내측으로 걸림돌기(20)가 형성되며, 이와 대칭이 되는 일측에는 복수개의 열선내설홈(11)이 마련되고 그 외측으로 커버삽입홈(23)이 형성된다.In addition, the heat insulating means 101 is formed with a plurality of fastening grooves 22 corresponding to the fastening grooves 22a of the door frame at one side, and at the same time, the locking projections 20 are formed in the inside of the grooves 22, and symmetrical thereto. A plurality of hot wire inner grooves 11 are provided at one side thereof, and a cover insertion groove 23 is formed at an outer side thereof.

상기와 같이 구성되는 본 발명의 냉동창고용 방열문틀 구조는 단열수단(101)을 알루미늄이나 동등의 비철금속제로 구성시킴으로서 제상열선의 온도를 높여 문틀자체에서 수분을 증발시켜 고무패킹(미도시)이 얼어붙는 것을 방지함으로서 그 단열효과는 극대화하고 열전도율을 향상시킴으로서 문틀(100)전체에 골고루 열을 발생하게 하여 완벽한 방열 상태를 유지할 수 있다. 방열문(102)의 기능이 우수하다고 하더라도 그와 밀착이 되는 문틀(100)이 제 기능을 발휘하지 못하게 되면 사용자가 원하는 최대의 방열 상태는 얻을 수가 없는 것이다.The heat dissipation door frame structure of the freezer warehouse of the present invention configured as described above is made of aluminum or equivalent non-ferrous metal to increase the temperature of the defrost heating wire to evaporate moisture in the door frame itself to freeze the rubber packing (not shown) By preventing the adhesion to maximize the thermal insulation effect and improve the thermal conductivity by generating heat evenly throughout the door frame 100 can maintain a complete heat dissipation state. Even though the function of the heat dissipation door 102 is excellent, if the door frame 100 which is in close contact with the heat dissipation function does not function properly, the maximum heat dissipation state desired by the user may not be obtained.

이상에서 상세히 살펴본 바와 같이 본 발명의 냉동창고용 방열문틀 구조는 그 구조가 간단하면서도 화재 발생이 없고 단열 상태를 최대한 유지할 수 있어 완벽한 방열문틀을 제공함은 물론 고품질의 방열문틀을 생산할 수 있는 등 그 기대되는 바가 다대한 발명이다.As described in detail above, the structure of the freezing warehouse heat dissipation door frame of the present invention is simple, yet does not cause a fire and can maintain the insulation state as possible to provide a perfect heat dissipation door frame, as well as to produce a high-quality heat dissipation door frame, etc. It is a great invention.
