【発明の詳細な説明】 産業上の利用分野 この発明は、冷凍・冷蔵庫用蒸発器に関する。[Detailed description of the invention] Industrial applications The present invention relates to an evaporator for freezers and refrigerators.
従来の技術
従来、冷凍・冷蔵庫の冷凍室と、これの下側の冷蔵室と
に、アルミニウム中ロールボンド材によりつくられた蒸
発器を配置することは既に知られている。BACKGROUND OF THE INVENTION It has been known in the past to arrange an evaporator made of roll bonded aluminum material in the freezing compartment of a refrigerator/freezer and in the refrigerating compartment below the compartment.
ここで、ロールボンド材は、上下一対のアルミニウム板
のいずれか一方の面に、接着防止材が所要形状に印刷さ

着部に導入せられて、これが管状に膨出せしめられるこ
とにより形成されたものである。Here, in the roll bond material, an anti-adhesive material is printed in the desired shape on one surface of a pair of upper and lower aluminum plates, and after the other surface is pressed onto this surface, fluid pressure is applied to the non-bonded areas. It is formed by introducing the tube into a tube and expanding it into a tubular shape.

したものが形成された。Problems to be Solved by the Invention However, in the manufacturing process of such roll-bonded materials, the outer surface of one of the upper and lower aluminum plates is pressed with a mold, and fluid is press-fitted into the non-bonded portion of both plates. The swelling tube part was formed to protrude only on one side that was not pressed by the mold.

なく、性能が低下するという問題があった。Then, the evaporator section on the side of the freezer compartment of the freezer/refrigerator, the evaporator section on the side of the refrigerator compartment below the freezer compartment, and the connecting section that connects the two,
When forming a single-sided expansion tube using a single roll bond material as described above, the expansion tube-shaped refrigerant passage in the evaporation section of the freezer compartment, especially in the bottom wall portion, is arranged to face the outside (lower side) of the freezer compartment. In this case, the refrigerant passage of the evaporation section on the rear wall of the refrigerator compartment is on the same side as this, so in the refrigerator compartment, this is on the inside (
If the evaporator is directly visible from the refrigerator compartment, the appearance will deteriorate due to the presence of the expanded tube-shaped refrigerant passage, or the evaporator will be located behind the rear wall of the refrigerator compartment. If the evaporation section is not visible from the refrigerator compartment, there is no problem with the appearance.11 Since the expanded tube-shaped refrigerant passage is in contact with the rear wall of the refrigerator compartment, the contact area of the evaporation section is small, and performance is affected. There was a problem that the value decreased.

冷蔵庫用蒸発器を提供しようとするにある。An object of the present invention is to solve the above-mentioned problems of the prior art, and in a freezer/refrigerator, an evaporator section on the side of the freezer compartment, an evaporator section on the side of the refrigerator compartment, and a connecting section connecting the two are integrated into a single piece of a single-sided expansion tube. Even when formed using a roll bond material, both the refrigerant passage part of the evaporation part on the freezer compartment side and the refrigerant passage part of the evaporation part on the refrigerator compartment side can be arranged facing outward, Therefore, if the evaporation part is directly visible from inside the refrigerator,
Since there is no expanded tube-shaped refrigerant passage and it is flat, it has an excellent appearance.Also, if the evaporation part is placed behind the rear wall of the refrigerator compartment and the evaporation part is not visible from inside the refrigerator compartment,
Since the flat side comes into contact with the rear wall of the refrigerator compartment, the contact area of the evaporator is extremely wide, greatly increasing performance.
We are trying to provide an evaporator for refrigerators.

It is formed using a single sheet of roll-bonded material with a single-sided expansion tube, and the strip-shaped connection part is twisted at the middle part of the height, so that it can be used for the expansion tube-shaped refrigerant passage part of the evaporation part on the freezer compartment side, and on the refrigerator compartment side. The expanding tube-shaped refrigerant passages of the evaporator can all be placed facing outward, and the flat side of the evaporator is located inside the refrigerator compartment, so the evaporator can be seen directly from inside the refrigerator compartment. If the evaporator is located behind the rear wall of the refrigerator, the flat surface of the evaporator will come into contact with the rear wall of the refrigerator, so the contact area of the evaporator will be wide. Performance increases significantly.
