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、図３に基いて保冷ウイング車両の構成について説明する。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、その基端部は荷台の前壁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）を介し枢支されて、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 structure of the cold insulated wing vehicle will be described with reference to FIG. A pair of left and right L-shaped roofs 1 of the cold insulation wing car are formed by a ceiling part 1a and a side wall part 1b, and the base end part thereof is hinged to a center beam 4 erected at the upper center of the front wall 2 and the rear wall 3 of the cargo bed. It is pivotally supported via 5 (FIG. 1) and can be opened and closed up and down. And the ceiling part 1a, the side wall part 1b, or the floor of the L-shaped roof 1 is filled with a cold insulation material to form a cold insulation 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危険が大であった。又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温
度上昇の原因となっていた。 Because of this structure, as shown in FIG. 4, condensation 6 is generated on the side surface of the center beam 4 during cooling, and it drops as water droplets in the cool box, and there is a great risk of wetting the cargo in the box. It was. 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, it has been a cause of the rise in the internal temperature that is kept cold by the convection phenomenon here.

そこで、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。   Therefore, an object of the present invention is to prevent condensation that occurs in the center beam, and also to prevent a hot air layer from being generated in the spaces on both sides of the center beam, thereby increasing the thermal efficiency of the cold insulated wing vehicle.

保冷ウイング車両において、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た。
また、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おり、該空間内に充填する断熱材はヒンジ等の空間内に突出する部材との干渉を避けるべく、断熱材に切欠加工を加えて充填した。 In a cold insulated wing vehicle, a space existing on both sides of the center beam was filled with a heat insulating material.
Further, the space existing on both sides of the center beam has a center beam, a pair of left and right cold insulation covers attached to the bottom of the center beam, and attached with a cold insulation gasket at the end and connected via a spacer made of a heat insulating resin plate. The thermal insulation material enclosed in the canvas sheet covering the top of the center beam and the base end portion of the wing with the cold insulation sheet attached to the end face interferes with a member projecting into the space such as a hinge. In order to avoid this, the insulating material was filled with a notch.

センタービーム４の両側部空間７を断熱空間とし、さらにこの中に断熱材８を埋め込んだことにより、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。又この構造により、センタービーム４周面での結露の発生を抑えることができ、熱効率の向上とともに水に弱い商品の保冷輸送に好適である。又たとえ少量の結露の発生があったとしても、空間７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 making the both-side space 7 of the center beam 4 into a heat insulating space and further embedding the heat insulating material 8 in this space, it is possible to prevent air convection in this portion, and to suppress heat conduction by convection, The cold storage performance in the refrigerator can be further improved. Moreover, this structure can suppress the occurrence of dew condensation on the circumferential surface of the center beam 4 and is suitable for cold transport of merchandise that is vulnerable to water with improved thermal efficiency. Even if a small amount of condensation occurs, the space 7 is surrounded by a heat insulating structure, so that it is possible to completely prevent the condensation from falling into the cabinet.

図１は本発明の要部即ちセンタービーム部の縦断面図である。符号８はセンタービーム４の両側に生じた空間７に嵌装した断熱材たとえばポリエチレンブロックである。断熱材８は予め成形された成型体で、これでセンタービーム４の両側の空間７を埋めることによって、空間７内の空気層をなるべく少なくすることにより空間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 main portion of the present invention, that is, a center beam portion. Reference numeral 8 denotes a heat insulating material such as a polyethylene block fitted in the space 7 formed on both sides of the center beam 4. The heat insulating material 8 is a pre-molded molded body. By filling the space 7 on both sides of the center beam 4 with this, the air layer in the space 7 is reduced as much as possible to prevent convection of air in the space 7, Heat conduction by convection can be suppressed.

図１及び図２・ｂで明らかなごとく、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 the cold-storage vehicle embodying the present invention. 2a is a partial perspective view, and b is an exploded view.
As apparent from FIG. 1 and FIG. 2B, a heat insulating material 8 is inserted into both side spaces 7 of the center beam 4 to remove the convection space of hot air.

空間７の上部はキャンバスシート９で覆われ（図１）、又空間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と１２の端部に取付けられている。保冷カバー１１と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。   The upper portion of the space 7 is covered with a canvas sheet 9 (FIG. 1), 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 ends of the cold insulation covers 11 and 12 made of an aluminum material that covers the lower part of the center beam 4. The cold insulation covers 11 and 12 are connected to the center beam 4 by a rivet 13 via a spacer 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は上部はキャンバスシート９よりなる上部のカバーと、両側部は保冷シート１５を取付けたウイングの基端部と、そして下部は両側に保冷ガスケット１０を備え、断熱樹脂板装のスペーサ１４を介して連結された保冷カバー１１と１２で覆われ、この保冷空間内に嵌装された断熱材８によって空間７のほとんどが充たされ、対流空間をなくしている。前記ウイングのヒンジ５は、センタービーム４にリベット結合されており、空間７内にヒンジ５の出張り等幾つかの突出部があるが、この部分は断熱材８に適宜切欠加工を施して充填している。   Thus, the space 7 on both sides of the center beam 4 has an upper cover made of a canvas sheet 9 on the upper side, a base end portion of a wing to which the cold insulation sheet 15 is attached on both sides, and a cold insulation gasket 10 on both sides on the lower side. The space 7 is covered with the heat insulating covers 11 and 12 connected via the spacer 14 of the heat insulating resin plate, and the space 7 is filled with the heat insulating material 8 fitted in the cold space, thereby eliminating the convection space. Yes. The hinge 5 of the wing is rivet-coupled to the center beam 4, and there are some protrusions such as a protrusion of the hinge 5 in the space 7, but this part is filled by applying appropriate notches to the heat insulating material 8. is doing.
