Description

대류에 의한 열전달에 의해 제품의 온도를 유지하기 위한 온도유지팩{TEMPERATURE MAINTAINING PACK}TEMPERATURE MAINTAINING PACK for maintaining the temperature of the product by heat transfer by convection

본 발명은 대류에 의한 열전달에 의해 제품의 온도를 유지하기 위한 온도유지팩에 관한 것이다. The present invention relates to a temperature holding pack for maintaining the temperature of the product by heat transfer by convection.

본 발명은 냉각팩에 관한 것으로서 자세하게는 식자재를 배송할 때 사용하는 냉동팩/냉장팩에 관한 것이다. 종래에 식자재를 소포/등기/택배등의 서비스를 이용하여 배송하게 되는 경우에 온도유지팩(이하, ‘냉동팩, 냉장팩‘을 통틀어 온도유지팩이라 한다)을 제품포장상자의 바닥이나 뚜껑쪽에 부착하여 제품의 신선도가 유지되도록 한다. 그런데 이러한 경우는 열의 전도에 의하여 냉각을 시키는 것이 아니라 대류에 의하여 냉각을 시키도록 하는데 온도유지팩과 제품 사이에 공간이 많이 있으며 제품은 충격으로부터 보호하기 위하여 비닐과 같은 것으로 쌓여 있기 때문에 온도유지팩을 이용하여 온도를 유지하기 에는 효율이 떨어진다. The present invention relates to a cooling pack, and more particularly, to a refrigeration pack / refrigeration pack for use when delivering food materials. Conventionally, when food materials are delivered using services such as parcel / registration / courier service, a temperature preservation pack (hereinafter referred to as a temperature preservation pack, referred to as a “frozen pack, a refrigerated pack”) is placed on the bottom or lid side of a product packaging box. To maintain the freshness of the product. However, in this case, it is not cooled by conduction of heat, but by convection. There is a lot of space between the temperature holding pack and the product. It is not efficient to maintain temperature.

때문에 배송에 있어서는 대류보다는 전도를 이용하여 냉각을 하는 방법이 많이 사용되어 왔는데 전도는 물체와 물체가 닿아서 열이 전달되는 형태이기 때문에 딱딱한 용기에 넣을 수 있는 것이나 어느 정도의 경도를 갖고 있는 것에 사용되어 왔다. Therefore, in the delivery, the method of cooling by using conduction rather than convection has been used a lot.The conduction is a form in which heat is transferred by contacting an object with an object, so it can be put in a rigid container or used to have a certain degree of hardness. Has been.

그런데, 육류나 채소와 같은 경우 온도 유지팩이 직접 닿게 되면 물러버리는 경우가 생겨 사용하지 못하고 효율이 낮더라도 비닐과 같은 것으로 둘둘 말아 싼 이후에 대류를 이용한 방법으로 온도를 유지하여 배송을 하였다. However, in the case of meat or vegetables, if the temperature maintenance pack is in direct contact, the case may be thrown back, and even if the efficiency is low, it is wrapped like a vinyl even though the efficiency is low.

이와 관련하여 대한민국 실용신안 등록번호 제200440614호 '용기 냉장팩'이나 대한민국 실용신안 등록번호 제20-035923호 ‘소형냉매팩’의 경우 이러한 문제점을 해결하기 위해서 나온 것이지만 특히 낮은 온도를 유지하기 위한 경우나 플라스틱용기에 담긴 제품등을 보관 하는데는 크게 도움이 되지 못하였다In this regard, the Korean Utility Model Registration No. 200440614 'Container Refrigeration Pack' or the Korean Utility Model Registration No. 20-035923 'Small Refrigerant Pack' are intended to solve this problem, but especially to maintain a low temperature. B. It was not very helpful to store the products in plastic containers.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된것으로서, 채소나 육류를 포장하는 경우에도 비닐로 싼 후에 냉동팩과 포장하지 않아도 대류에 의한 냉각에 의하여 신선함을 유지시킬 수 있도록 하는 냉각매트를 제공하는 것을 목적으로한다. The present invention has been made in order to solve the problems described above, even when packaging vegetables or meat, even if the packaging is wrapped in plastic, without the freezing pack and packaging, cooling mat to maintain the freshness by cooling by convection The purpose is to provide.

상기한 바와 같은 목적을달성하기 위하여 대류에 의한 열전달에 의해 제품의 온도를 유지하기 위한 온도유지팩을 제공하는데 바닥부(11)위에 반원형상의 단면을 갖는 돌기(12)가 형성이 되는데 바닥부(11)는 미리 정해진 부분까지 기계적인 지지를 위한 지지층(13)이 형성되며 돌기의 내부와 바닥부(11)에서 지지층(13)을 제외한 부분은 냉매와 공기층이 형성될 수 있다. In order to achieve the object as described above, to provide a temperature maintaining pack for maintaining the temperature of the product by heat transfer by convection, the projection 12 having a semi-circular cross-section is formed on the bottom 11, the bottom ( 11, the support layer 13 for mechanical support is formed up to a predetermined portion, and the refrigerant and the air layer may be formed in portions of the protrusions and the bottom 11 except for the support layer 13.

상기한 바와 같은 온도유지팩에 의하여 채소, 배추, 육류도 손상되지 않은 상태로 배송, 보관이 가능하게 하는 효과가 있다By the temperature maintenance pack as described above, vegetables, cabbages, meat are also intact and can be shipped and stored.

도1,2는 본발명에 따른 일실시예를 도시하는 도면1 and 2 show an embodiment according to the present invention.

이하, 첨부한 도면을 참고로 하여 본 발명을 상세하게 설명한다. 도1은 본 발명에 따른 일실시예를 도시하는 도면이다. 도1에서 본 발명에 따른 매트는 바닥부(11)위로 돌기(12)가 형성된 형태로서 돌기의 내부는 냉매가 채워져 있다. 그러나 냉매는 돌기(12)내부를 전부 채우는 것이 아니라 냉매와 공기가 함께 있는 형태로 되어 매트를 똑바로 놓았을 때 냉매가 아래쪽으로 가면서 위쪽에는 공기가 있는 부분이 닿게 되도록 한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is a diagram showing an embodiment according to the present invention. In FIG. 1, the mat according to the present invention has a protrusion 12 formed on the bottom 11, and the inside of the protrusion is filled with a refrigerant. However, the refrigerant is not filled with the inside of the projections 12, but the form of the refrigerant and the air together so that when the mat is placed upright, the refrigerant is directed to the bottom and the upper part is in contact with the air.

즉, 돌기(12)위에 놓이게 되는 채소와 고기는 돌기(12)에 의해서 매트로부터 일정높이만큼 들여올려지게 되어 냉매에 직접 닿게 되지는 않게 된다. 또한, 돌기(12)의 내부의 상단부분에는 냉매가 채워지는 것이 아니라 공기가 채워져 있기 때문에 돌기(12)에 닿는 부분도 냉매에 직접 닿게 되지는 않게 된다. In other words, the vegetables and meat to be placed on the projection 12 is lifted by a certain height from the mat by the projection 12 is not directly in contact with the refrigerant. In addition, since the upper end portion of the inside of the protrusion 12 is filled with air rather than a refrigerant, the part touching the protrusion 12 does not directly touch the refrigerant.

온도에 민감한 김치와 같은 발효제품은 기존의 방식으로는 아이스 팩을 통한 온도제어가 어려운데 흔히 마트의 가격할인 김치의 경우는 유통되는 중간에 발효가 진행되어 비닐포장이 빵빵하게 부풀어 올라 조금 더 있으면 터질 수도 있는 지경의 김치들이 할인으로 소진되고 있다. 그렇다고 발효를 늦추기 위해서 냉각팩을 사용하여 김치포장에 접촉시키게 되면 접촉되는 부분의 배추가 손상되는 경우가 많기 때문에 종래의 냉각팩은 사용하지 못하는 경우가 많았다. Fermentation products such as temperature-sensitive kimchi are difficult to control the temperature through ice packs in the conventional method. In the case of kimchi, the price discount of kimchi is often fermented in the middle of distribution, and the plastic packaging swells up and bursts. Capital Kimchi is running out of discounts. However, in order to slow the fermentation, when contacting the kimchi packaging using a cooling pack, the cabbage of the contacted parts are often damaged, so the conventional cooling packs were often not used.

그런데 본원 발명의 경우는 돌기(12)에 의해서 제품이 들어올려져서 매트와 분리될 뿐 아니라 직접닿게 되는 돌기부분의 상층은 기체로 채워지기 때문에 냉매가 직접닿지 않게 된다. 냉매로는 기존에 사용되는 액상, 기체상의 것이 사용될 수 있으며 에탄올이나 탄화수소 화합물 액체등이 사용될 수 있다. 따라서, 제품이 닿게 되는 부분은 냉매가 있는 부분이 아니라 기체가 있는 부분이며 냉매에 의한 열전달은 전도가 아니라 대류에 의해 이루어지게 된다. 즉, 냉매가 직접 닿지 않음으로 해서 종래에는 쉽게 손상되던 배추, 채소, 육류와 같은 제품들도 보관이 가능하게 된다.By the way, in the case of the present invention, the product is lifted by the projections 12 and separated from the mat, and the upper layer of the projections directly contacting is filled with gas so that the refrigerant does not directly contact. The refrigerant may be a liquid or gaseous phase used in the existing, and ethanol or a hydrocarbon compound liquid may be used. Therefore, the part where the product comes in contact is not the part with the refrigerant but the part with the gas and the heat transfer by the refrigerant is made by convection rather than conduction. In other words, it is possible to store products such as Chinese cabbage, vegetables, and meat, which are easily damaged by not directly contacting the refrigerant.

돌기(12)의 내부는 냉매와 기체로 채워지는데 냉매의 무게 때문에 바닥에 올려놓게 되면 냉매가 아래쪽으로 내려오게 된다. 도1에는 이러한 형태가 도시되어 있는데 지지판의 하단부는 매트의 기계적지지를 위한 고체부(13)가 형성이 되며 매트의 상단부와 돌기(12)의 하단부는 냉매(14)로 채워지며 돌기(15)의 상단은 공기층(15)이 형성된다The inside of the protrusion 12 is filled with a refrigerant and gas, but when placed on the floor due to the weight of the refrigerant, the refrigerant comes down. Figure 1 shows this form, the lower end of the support plate is formed with a solid portion 13 for the mechanical support of the mat, the upper end of the mat and the lower end of the projection 12 is filled with the refrigerant 14 and the projection 15 The top of the air layer 15 is formed

공기층은 대기압보다 높도록 하여 팽창된상태를 유지하도록 하여 제품에 의하여 눌린다고 하여도 냉매에 직접닿지 않게 할 수 있다. The air layer may be kept above the atmospheric pressure to maintain an expanded state, so that the air layer may not directly contact the refrigerant even when pressed by the product.

공기층은 격막을 따로 두어 아예 공기층과 냉매가 섞이지 않도록 할 수도 있으나 중력에 의하여 냉매가 아래쪽으로 가기 때문에 격만을 따로 둘 필요는 없는 경우가 많다. The air layer may have a diaphragm to prevent the air layer and the refrigerant from being mixed at all, but since the refrigerant goes downward by gravity, it is not necessary to separate the space alone.

또한 공기층과 냉매의 비율을 조절하여 공기층의 두께를 더 두껍게 하여 매트에서 전도가 일어나는 영역과 대류가 일어나는 영역을 넓이를 조절 할 수 있다. In addition, by adjusting the ratio of the air layer and the refrigerant, the thickness of the air layer can be made thicker to control the area where conduction and convection occur in the mat.

공기층의 비율이 높아질수록 대류에 의한 영향이 더 커지게 되며 대신 냉각시간은 길어지게 된다. The higher the proportion of the air layer, the greater the effect of convection and the longer the cooling time.

도2는 또다른 실시예를 도시한다. 도2는 돌기(12)의 또다른 예를 도시한것으로서 돌기(12)는 공기층(15)이 형성되어 있다. 위쪽으로 갈수록 폭이 좁아지고 서로 마주보고 휘어지는 형상을 하고 있으며 돌기(12)를 촘촘하게 할수록 하단의 바닥부(11)에 닿기 힘들게 되면서도 바닥부에 직접닿지는 않기 때문에 대류에 의한 열전달이 쉽게 일어나게 된다. 2 shows another embodiment. 2 shows another example of the projection 12, in which the projection 12 has an air layer 15 formed thereon. As the width is narrowed toward the upper side and curved to face each other, the denser the projections 12, the harder it is to reach the bottom part 11 at the bottom, but the heat transfer by convection occurs easily because it does not directly contact the bottom part.
