Description

本発明は、保冷ウイング車両におけるセンタービーム近傍の保冷構造に関するものである。 The present invention relates to a cold insulation structure near a center beam in a cold insulation wing vehicle.

まず、保冷ウイング車両の構成について説明する。図３に示すように、保冷ウイング車の左右一対のＬ型屋根１は、天井部１ａと側壁部１ｂとで形成され、その基端部が、荷台の前壁２と後壁３の上部中央に架設されたセンタービーム４に蝶番５（図１）を介して枢支されることにより、上下に開閉自在になっている。そして、Ｌ型屋根１の天井部１ａや側壁部１ｂあるいは床等は、保冷材を充填して保冷構造となっている。しかし、センタービーム４の両側部には空間が生じている。 First, the configuration of the cold insulation wing vehicle will be described. As shown in FIG. 3, a pair of left and right L-shaped roofs 1 of the cold insulated wing vehicle are formed by a ceiling portion 1 a and a side wall portion 1 b, and the base ends thereof are the upper center of the front wall 2 and the rear wall 3 of the loading platform By being pivotally supported by a center beam 4 erected through a hinge 5 (FIG. 1), it can be opened and closed up and down. And the ceiling part 1a, the side wall part 1b, the floor, etc. of the L-shaped roof 1 are filled with a cold insulating material and have a cold insulating structure. However, there is a space on both sides of the center beam 4.

このような構造であるから、図４に示す如く、冷却時にセンタービーム４の側面に結露６が生じ、これが保冷庫内に水滴となって落ち、庫内の貨物を濡らしてしまう恐れが大であった。また、ボデー全長に渡ってセンタービーム４の左右空間に熱い空間７が存在するので、ここでの対流現象によって、折角保冷されている庫内の温度が上昇する原因となっていた。 Because of this structure, as shown in FIG. 4, condensation 6 occurs on the side surface of the center beam 4 during cooling, and this is likely to drop as water droplets in the cool box and wet the cargo in the box. there were. In addition, since the hot space 7 exists in the left and right spaces of the center beam 4 over the entire length of the body, the convection phenomenon here has caused the temperature inside the storage chamber to be kept at an angle.

本発明は、センタービームに生ずる結露の防止、さらにはセンタービーム両側部にある空間に熱い空気層が生ずるのを防ぎ、保冷ウイング車の熱効率の増大を図ることを課題とする。   It is an object of the present invention to prevent condensation that occurs in the center beam, and also to prevent the formation of a hot air layer in the space on both sides of the center beam, thereby increasing the thermal efficiency of the cold insulated wing vehicle.

本発明は、保冷ウイング車両におけるセンタービームの両側部に存在する空間に断熱材を充填し、前記センタービームの両側部に存在する空間は、センタービームと、センタービームの底部に取付けられ、端部に保冷用ガスケットを取付け断熱樹脂板よりなるスペーサを介して連結した左右一対の保冷カバーと、センタービーム頂部を覆うキャンバスシートと、端面に保冷シートを取付けたウイングの基端部とで囲繞されていることを特徴とする。
本発明において、前記断熱材は、前記空間内に突出するヒンジ等の部材との干渉を避けるべく、切欠加工を加えて前記空間に充填されることが好ましい。 The present invention, a heat insulating material filled in a space existing on both sides of the definitive center beam in cold wing vehicle, space existing on both sides of the center beam has a center beam, attached to the bottom of the center beam, the end Surrounded by a pair of left and right cold insulation covers, which are connected to each other through a spacer made of a heat insulating resin plate, a canvas sheet covering the top of the center beam, and a base end portion of a wing with a cold insulation sheet attached to the end face It is characterized by.
In the present invention, the insulation, to avoid interference with the member such as a hinge which projects into the space, it is preferably filled in the space by adding the notch machining.

センタービームの両側部空間を断熱構造で囲繞して断熱空間とし、この中に断熱材を充填したことにより、この部分での空気の対流を防ぐことができ、対流による熱の伝導を抑えることができ、庫内の保冷性能を一段と向上させることができる。この構造により、センタービームの周面での結露の発生を抑えることができ、熱効率の向上を図ると共に、水に弱い商品の保冷輸送に好適である。また、たとえ少量の結露の発生があったとしても、空間の周囲を断熱構造で囲繞したので、結露が庫内に落下するのを完全に防止することができる。 By surrounding the space on both sides of the center beam with a heat insulating structure to make a heat insulating space and filling this with heat insulating material, air convection in this part can be prevented and heat conduction by convection can be suppressed. It is possible to further improve the cold storage performance in the cabinet. With this structure, it is possible to suppress the occurrence of dew condensation on the peripheral surface of the center beam, and to improve the thermal efficiency, it is suitable for cold transport of goods that are vulnerable to water. Further, even if a small amount of condensation occurs, the space is surrounded by a heat insulating structure, so that it is possible to completely prevent the condensation from falling into the cabinet.

図１は、本発明に係る保冷ウイング車両のセンタービーム部の縦断面図である。センタービーム４の両側に生じた空間７には、断熱材（たとえば、ポリエチレンブロック）８が嵌装されている。断熱材８は、予め成形された成型体からなり、これでセンタービーム４の両側の空間７を埋めることにより、空間７内の空気層を少なくして空間７内での空気の対流を防ぎ、対流による熱伝導を抑えることができる。 FIG. 1 is a longitudinal sectional view of a center beam portion of a cold insulated wing vehicle according to the present invention. The space 7 caused on both sides of the center beam 4, insulation (e.g., polyethylene block) 8 is fitted. Heat insulating material 8 is made of preformed molded, this more to fill both sides of the space 7 of the center beam 4, to prevent convection of air in the space 7 with less air layer in the space 7 The heat conduction by convection can be suppressed.

図２は、図１のセンタービーム４近傍の詳細図である。図２（ａ）は部分斜視図、（ｂ）は分解図である。図示のように、センタービーム４の両側部空間７には断熱材８を嵌挿して、熱風の対流空間を除去している。 FIG. 2 is a detailed view of the vicinity of the center beam 4 of FIG. 2A is a partial perspective view, and FIG. 2B is an exploded view. As shown in the drawing, a heat insulating material 8 is fitted into both side spaces 7 of the center beam 4 to remove a convection space for hot air.

図１に示すように、空間７の上部はキャンバスシート９で覆われ、空間７の下部両側は保冷ガスケット１０でシールされている。保冷ガスケット１０は、センタービーム４の下部を覆うアルミ型材製の保冷カバー１１、１２の端部に取付けられている。図２（ｂ）に示すように左右一対の保冷カバー１１、１２は、センタービーム４に対し、断熱効果を有する樹脂板よりなるスペーサ１４を介して、リベット１３で連結されている。ウイングの基端部には、保冷シート１５が取付けられている。 As shown in FIG. 1, the upper portion of the space 7 is covered with a canvas sheet 9, and both lower sides of the space 7 are sealed with a cold insulation gasket 10. The cold insulation gasket 10 is attached to the end portions of the cold insulation covers 11 and 12 made of an aluminum material that covers the lower portion of the center beam 4. As shown in FIG. 2B, the pair of left and right cold insulation covers 11 and 12 are connected to the center beam 4 by rivets 13 via spacers 14 made of a resin plate having a heat insulating effect. A cold insulation sheet 15 is attached to the base end of the wing.

かくして、センタービーム４の両側部の空間７においては、上部はキャンバスシート９よりなる上部のカバーで、両側部は保冷シート１５を取付けたウイングの基端部で、下部は、両側に保冷ガスケット１０を備え断熱樹脂板製のスペーサ１４を介して連結された保冷カバー１１と１２で、それぞれ覆われる。そして、この保冷空間内に嵌装された断熱材８によって空間７の殆どが充たされ、対流空間をなくしている。
また、空間７内では、前記ウイングのヒンジ（蝶番）５がセンタービーム４にリベット結合されており、該ヒンジ５の出張り等幾つかの突出部があるが、断熱材８は、このような突出部分との干渉を避けるべく切欠加工を施して充填される。 Thus, in the space 7 on both sides of the center beam 4 , the upper part is the upper cover made of the canvas sheet 9, the both side parts are the base ends of the wings to which the cold insulation sheet 15 is attached, and the lower part is the cold insulation gasket 10 on both sides. Are provided with cold insulation covers 11 and 12 connected via spacers 14 made of a heat insulating resin plate . And most of the space 7 is filled with the heat insulating material 8 fitted in this cold insulation space, and the convection space is eliminated.
Also, within the space 7, the wings of the hinges 5 are riveted to the center beam 4, but there are several protrusions such lugs of the hinge 5, the heat insulating material 8 is, like this In order to avoid interference with the projecting portion, it is filled with a notch.
